    We adapted the English International Index of Erectile Function (IIEF) into Malay. This was difficult as many sex-related terms do not exist in colloquial Malay. In the pretest, there was no difficulty with comprehension and all subjects judged the Malay IIEF equivalent to the English IIEF. After slight modification, a final instrument was evaluated in two studies. Study A included 136 subjects. It showed that the instrument had good reliability and discriminant validity. The factor structure of the English IIEF was not reproducible. Study B included 26 ED subjects who underwent oral sildenafil therapy. The Malay IIEF was sensitive to treatment response. The area under the ROC curve of the Malay IIEF-5 was 0.86; the optimal cutoff score has a sensitivity of 85% and specificity of 75%. The results suggest that the Malay IIEF requires more work, but the Malay IIEF-5 has acceptable measurement properties to recommend its use in clinical practice and research.

    Full Text Available Male sexual dysfunction is an increasing problem across a variety of general and clinical populations, such as cancer populations; especially among prostate cancer patients who tend to receive treatments that often result in erectile dysfunction (ED and/or premature ejaculation (PE. Therefore, in order to diagnose ED and PE in these populations, adequate and efficient instruments such as the International Index of Erectile Function 5-item version (IIEF-5 and the Premature Ejaculation Diagnostic Tool (PEDT are needed. However, since this is an important topic additional evidence of psychometric properties of the IIEF-5 and the PEDT in such samples are required. Thus the aim of the present study was to use Rasch models to investigate the construct validity, local dependency, score order, and differential item functioning (DIF of both questionnaires in a sample of prostate cancer patients.Prostate cancer patients (n = 1058, mean±SD age = 64.07±6.84 years who visited urology clinics were invited to fill out the IIEF-5 and the PEDT. Construct validity was examined using infit and outfit mean square (MnSq and local dependency using correlations between each two residual Rasch scores. Score order was investigated using step and average measures of difficulty and DIF using DIF contrast.All IIEF-5 and PEDT items had acceptable infit and outfit MnSq. Step measures revealed that all but two items had disordered categories in terms of scores 1 to 3. Only one local dependency was found, and no items displayed DIF across age, educational level, and help seeking.The results showed that both the IIEF-5 and the PEDT had sound psychometric properties in the Rasch analyses, although some score disordering could be detected in both instruments. The results of no DIF items in both instruments suggest using them to compare ED and PE across age and educational level is adequate.

    To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach's α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, pPortuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients' psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well-being feeling.

    Purpose: To evaluate erectile function after permanent prostate brachytherapy using a validated patient-administered questionnaire and to determine the effect of multiple clinical, treatment, and dosimetric parameters on penile erectile function. Methods and materials: A total of 226 patients with preimplant erectile function determined by the International Index of Erectile Function (IIEF) questionnaire underwent permanent prostate brachytherapy in two prospective randomized trials between February 2001 and January 2003 for clinical Stage T1c-T2c (2002 American Joint Committee on Cancer) prostate cancer. Of the 226 patients, 132 were potent before treatment and, of those, 128 (97%) completed and returned the IIEF questionnaire after brachytherapy. The median follow-up was 29.1 months. Potency was defined as an IIEF score of ≥13. The clinical, treatment, and dosimetric parameters evaluated included patient age; preimplant IIEF score; clinical T stage; pretreatment prostate-specific antigen level; Gleason score; elapsed time after implantation; preimplant nocturnal erections; body mass index; presence of hypertension or diabetes mellitus; tobacco consumption; the volume of the prostate gland receiving 100%, 150%, and 200% of the prescribed dose (V 100/150/200 ); the dose delivered to 90% of the prostate gland (D 90 ); androgen deprivation therapy; supplemental external beam radiotherapy (EBRT); isotope; prostate volume; planning volume; and radiation dose to the proximal penis. Results: The 3-year actuarial rate of potency preservation was 50.5%. For patients who maintained adequate posttreatment erectile function, the preimplant IIEF score was 29, and in patients with brachytherapy-related ED, the preimplant IIEF score was 25. The median time to the onset of ED was 5.4 months. After brachytherapy, the median IIEF score was 20 in potent patients and 3 in impotent patients. On univariate analysis, the preimplant IIEF score, patient age, presence of nocturnal

    Purpose: To evaluate long-term changes in erectile function following prostate brachytherapy. Methods and Materials: This study included 226 patients with prostate cancer and preimplant erectile function assessed by the International Index of Erectile Function-6 (IIEF-6) who underwent brachytherapy in two prospective randomized trials between February 2001 and January 2003. Median follow-up was 6.4 years. Pre- and postbrachytherapy potency was defined as IIEF-6 ≥ 13 without pharmacologic or mechanical support. The relationship among clinical, treatment, and dosimetric parameters and erectile function was examined. Results: The 7-year actuarial rate of potency preservation was 55.6% with median postimplant IIEF of 22 in potent patients. Potent patients were statistically younger (p = 0.014), had a higher preimplant IIEF (p < 0.001), were less likely to be diabetic (p = 0.002), and were more likely to report nocturnal erections (p = 0.008). Potency preservation in men with baseline IIEF scores of 29-30, 24-28, 18-23, and 13-17 were 75.5% vs. 73.6%, 51.7% vs. 44.8%, 48.0% vs. 40.0%, and 23.5% vs. 23.5% in 2004 vs. 2008. In multivariate Cox regression analysis, preimplant IIEF, hypertension, diabetes, prostate size, and brachytherapy dose to proximal penis strongly predicted for potency preservation. Impact of proximal penile dose was most pronounced for men with IIEF of 18-23 and aged 60-69. A significant minority of men who developed postimplant impotence ultimately regained erectile function. Conclusion: Potency preservation and median IIEF scores following brachytherapy are durable. Thoughtful dose sparing of proximal penile structures and early penile rehabilitation may further improve these results.

    Purpose: To determine the incidence of potency preservation after permanent prostate brachytherapy using a validated patient-administered questionnaire and to evaluate the effect of multiple clinical and treatment parameters on penile erectile function. Methods and Materials: Four hundred twenty-five patients underwent permanent prostate brachytherapy from April 1995 to October 1999. Two hundred nine patients who were potent before brachytherapy and who at the time of the survey were not receiving hormonal therapy were mailed the specific erectile questions of the International Index of Erectile Function (IIEF) questionnaire with a self-addressed stamped envelope. The questionnaire consisted of 5 questions, with a maximal score of 25. Of the 209 patients, 181 (87%) completed and returned the questionnaire. The mean and median follow-up was 40.4±14.9 and 40.6 months, respectively (range 19-75). Preimplant erectile function was assigned using a three-tiered scoring system (2 = erections always or nearly always sufficient for vaginal penetration; 1 = erections sufficient for vaginal penetration but considered suboptimal; 0 = the inability to obtain erections and/or erections inadequate for vaginal penetration). Postimplant potency was defined as an IIEF score ≥11. The clinical parameters evaluated for erectile function included patient age, preimplant potency, clinical T-stage, pretreatment prostate-specific antigen level, Gleason score, elapsed time after implantation, hypertension, diabetes mellitus, and tobacco consumption. Treatment parameters included radiation dose to the prostate gland, use of hormonal manipulation, use of supplemental external beam radiotherapy (EBRT), choice of isotope, prostate volume, and planning volume. The efficacy of sildenafil citrate in brachytherapy-induced erectile dysfunction (ED) was also evaluated. Results: Pretreatment erectile function scores of 2 and 1 were assigned to 125 and 56 patients, respectively. With a 6-year follow

    For localized prostate cancer, treatment options include external beam radiotherapy (EBRT), radical prostatectomy (RP), and brachytherapy (BT). Erectile dysfunction (ED) is a common side-effect. Our aim was to evaluate penile erectile function (EF) before and after BT, EBRT, or RP using a validated self-administered quality-of-life survey from a prospective registry. Analysis included 478 patients undergoing RP (n = 252), EBRT (n = 91), and BT (n = 135) with at least 1 year of follow-up and EF documented using IIEF-5 scores at baseline, 6 weeks, 6 months, 1 year, and annually thereafter. Differences among treatments were most pronounced among patients with no or mild initial ED (IIEF-5 ≥ 17). Overall, corrected for baseline EF and age, BT was associated with higher IIEF-5 scores than RP (+ 7.8 IIEF-5 score) or EBRT (+ 3.1 IIEF-5 score). EBRT was associated with better IIEF-5 scores than RP (+ 4.7 IIEF-5 score). In patients undergoing EBRT or RP with bilateral nerve sparing (NS), recovery of EF was observed and during follow-up, the differences to BT were not statistically significant. Overall age had a negative impact on EF preservation (corrected for baseline IIEF). In our series, EF was adversely affected by each treatment modality. Considered overall, BT provided the best EF preservation in comparison to EBRT or RP. (orig.) [de

    To assess sexual function in young men with spina bifida and myelomeningocele. Between November 2003 and February 2004, a cross-sectional study was performed in 55 men older than 18 years of age who had been regularly followed up for myelomeningocele since childhood, between 1961 and 1985, in the Pediatric Internal Surgery Department. The International Index of Erectile Function (IIEF) questionnaire was mailed to each man. The response rate was 72.7%. Of the 40 men who replied, 16 (40%) had had sexual intercourse at least once during the previous month. These were the older men (age 31.9 +/- 5.7 years versus 27.7 +/- 5.5 years, P = 0.027). The IIEF scores for the whole group were erectile function 11.61 +/- 9.44, orgasmic function 3.53 +/- 3.86, sexual desire 6.94 +/- 2.4, intercourse satisfaction 3.7 +/- 4.81, and overall satisfaction 4.7 +/- 3.34. According to the classification of Cappelleri, of the 16 men who had had sexual intercourse during the previous month, 4 had no erectile dysfunction, 3 had mild, 4 mild to moderate, and 5 severe dysfunction. Erectile function was statistically related to the ability to maintain erections (mean IIEF score 4 and 5 for men with no erectile dysfunction versus a mean IIEF score of 4 and 5 for men with erectile dysfunction: 4.75 +/- 0.5 versus 2.00 +/- 1.32, P = 0.011 for IIEF score of 4 and 4.50 +/- 1.5 versus 3 +/- 2, P = 0.040 for IIEF score of 5). Young adult men with spina bifida and myelomeningocele begin sexual activity late. Moreover, 75% have erectile dysfunction that is related to difficulty in maintaining erections.

    Erectile dysfunction (ED) is highly prevalent in obstructive sleep apnea (OSA), however, the effect of continuous positive airway pressure (CPAP) therapy on erectile function has not yet been thoroughly investigated in these patients. Ninety-four men with severe OSA (ie, with an apnea-hypopnea-index ≥ 30/h of sleep) were prospectively evaluated for the presence and severity of ED before and after 6-12 months of CPAP therapy. The abbreviated version of the International Index of Erectile Function, (the IIEF-5) was used to rate erectile function. Furthermore, all study participants responded to standard questionnaires of daytime sleepiness (Epworth Sleepiness Scale), quality of life (WHO Wellbeing 5 questionnaire) and depression (Major Depression Inventory). ED as defined by an IIEF-5 score of ≤21 was present in 64 patients (68.1%). CPAP treatment significantly improved erectile function in those patients suffering from moderate and severe ED. Additionally, a trend for a correlation between the improvement of erectile function under CPAP and the hours of its use was observed. Finally, this effect was associated with larger improvements of quality of life in affected patients. ED is very frequent in men with severe OSA and can at least partly be reversed by long-term CPAP therapy in most seriously affected patients. The beneficial effect on erectile function may depend on CPAP compliance and is accompanied by improvements of quality of life. Randomized controlled trials are needed to confirm these findings.

    Full Text Available The aim of this study was to evaluate erectile function in patients with panurethral stricture after urethral reconstruction. Totally, 65 patients were enrolled. Different urethral reconstructions were performed according to the details of urethral strictures. The erectile function was evaluated before and after surgery. The length and location of stricture and duration from initial diagnosis to operation were recorded. The International Index of Erectile Function-5 (IIEF-5 scores, the quality of life (QoL scores and the maximal flow rate were obtained before and 3, 6, and 12 months after surgery. A significant improvement in QoL and maximal flow rate was observed 3, 6, and 12 months after surgery compared with those observed before surgery (P < 0.05. An impairment of erectile function was observed in patients with multi-site stricture 3 months after surgery (P < 0.05. Subsequently, these patients recovered 6 and 12 months after surgery. Three months after surgery, the IIEF-5 scores in patients with anterior urethral stricture were higher than those with multi-site stricture. Similar results were observed 6 and 12 months after surgery. No significant difference in age or duration from initial diagnosis to final operation was observed between patients with erectile dysfunction after surgery and patients with normal erectile function. However, a linear regressive relationship was detected between IIEF-5 scores and location of urethral stricture. Surgical reconstruction for treating panurethral strictures has limited effects on erectile function. The location of the stricture, particularly when extended to posterior urethra, was found to be associated with erectile function after surgery.

    Full Text Available INTRODUCTION: The present study aims to prospectively compare the sexual function in males before and after vasectomy surgery using the international index of erectile function (IIEF. MATERIALS AND METHODS: From October to December 2002, sixty-four patients who were candidates for male sterilization in the vasectomy program of the Urology Section at the General Hospital of the University of São Paulo were included. The same investigator applied the IIEF before and 90 days after the surgery. The mean scores obtained on pre and postoperative visits for all domains of sexual function were analyzed and compared with the Wilcoxon test. RESULTS: The mean patient age was 35 years (range from 25 to 48 years and the mean number of children per man was 3. The total mean score of the IIEF was 64.06 before surgery and 65.64 after the procedure, with this difference considered statistically significant (p < 0.001. Sixty-seven per cent of the patients improved their scores, versus 17% and 16% who showed worsening or no change at all in IIEF scores following surgery, respectively. Of the 5 sexual function domains, desire and sexual satisfaction presented statistically significant improvement. CONCLUSION: This study showed that vasectomy caused a positive impact on sexual function, especially on desire and sexual satisfaction, in the majority of men undergoing surgery. There was no case of surgery-related erectile dysfunction.

    Full Text Available Background: Patients with Chronic Heart Failure (CHF have been shown to have enhanced risk of Erectile Dysfunction (ED due to low cardiac output, endothelial dysfunction, medications, co-morbid conditions, and psychogenic factors. Objectives: The present study aimed to evaluate the effects of sildenafil on erectile function of patients with stable CHF using the abridged 5-item version of the International Index of Erectile Function (IIEF-5. Patients and Methods: Using convenience sampling, 222 sexually-active adult males with NYHA class I-III stable CHF were included in this cross-sectional study. All the patients filled out the IIEF-5 questionnaire, in which they were required to score the five domains of male sexual function, including erectile function, orgasm function, sexual desire, intercourse satisfaction, and overall satisfaction. All the analyses were performed using the SPSS statistical software (v. 19 and P < 0.05 was considered as statistically significant. Results: In our sample, the patients’ mean age was 47.14 ± 11.86 years, their mean left ventricular ejection fraction was 20% (15% - 25%, and the prevalence of ED was 70.3%. In addition, severe, moderate, mild to moderate, and mild ED were seen in 57%, 17%, 7%, and 19% of the patients with ED, respectively. ED was significantly more prevalent in the patients with ischemic heart failure compared to those with idiopathic dilated cardiomyopathy (84.68% vs. 55.85%, P < 0.001. Moreover, the prevalence of ED was significantly lower in the patients taking sildenafil compared to the other group (42.85% vs. 82.89%, P < 0.001. Conclusions: Sildenafil appears to provide satisfactory results toward improving sexual function in patients with CHF.

    For localized prostate cancer, treatment options include external beam radiotherapy (EBRT), radical prostatectomy (RP), and brachytherapy (BT). Erectile dysfunction (ED) is a common side-effect. Our aim was to evaluate penile erectile function (EF) before and after BT, EBRT, or RP using a validated self-administered quality-of-life survey from a prospective registry. Analysis included 478 patients undergoing RP (n = 252), EBRT (n = 91), and BT (n = 135) with at least 1 year of follow-up and EF documented using IIEF-5 scores at baseline, 6 weeks, 6 months, 1 year, and annually thereafter. Differences among treatments were most pronounced among patients with no or mild initial ED (IIEF-5 ≥ 17). Overall, corrected for baseline EF and age, BT was associated with higher IIEF-5 scores than RP (+ 7.8 IIEF-5 score) or EBRT (+ 3.1 IIEF-5 score). EBRT was associated with better IIEF-5 scores than RP (+ 4.7 IIEF-5 score). In patients undergoing EBRT or RP with bilateral nerve sparing (NS), recovery of EF was observed and during follow-up, the differences to BT were not statistically significant. Overall age had a negative impact on EF preservation (corrected for baseline IIEF). In our series, EF was adversely affected by each treatment modality. Considered overall, BT provided the best EF preservation in comparison to EBRT or RP. (orig.)

    The relation between Erection Hardness Score (EHS) and The International Erectile Function Index (IIEF) Questionnaire- Erectile Function Domain Score (IIEF-EF score) used in erectile dysfunction (ED) evaluation and the prevalence of priapism after penile Doppler ultrasonography (PDU) was examined in this study. A total of 62 patients who had PDU were included in the study. Patients were divided into two groups; there were 33 patients in IIEF-EF score ≤10, EHS 10, EHS ≥2 group (Group 2). The two groups separated according to their scores were compared for age, body mass index (BMI), prevalence of priapism, vascular comorbidities and duration of erection. When compared to Group 2, median age, rate of vascular comorbidities rate and BMI were detected to be higher in Group 1 with IIEF-EF score ≤10 and EHS 10 and EHS ≥2 (p<0.001, p=0.027, p=0.049 respectively). High IIEF-EF and EHS scores, younger ages and lower rates of vascular comorbidities in patients from whom PDU was demanded increase the prevalence of priapism.

    We conducted this prospective comparative study to examine the hypothesis that varicocele was associated with hypogonadism and impaired erectile function as reflected in International Index of Erectile Function-5 (IIEF-5) scores as well as nocturnal penile tumescence and rigidity (NPTR) parameters. From December 2014 to December 2015, a total of 130 males with varicocele complaining of infertility or scrotal discomfort and 130 age-matched healthy males chosen from volunteer healthy hospital staff as controls were recruited in this study. Serum testosterone (TT) levels and IIEF-5 scores as well as NPTR parameters were evaluated and compared between varicocele and control subjects. All participants were further grouped into hypogonadism based on the cut-off value 300 ng/dL. A total of 45 of 130 patients were identified as hypogonadism, while it was not found in control subjects. A multivariate logistic regression with likelihood ratio test revealed that TT levels as well as grade III and II varicocele posed significant indicators for hypogonadism occurrence (chi-square of likelihood ratio = 12.40, df = 3, p hypogonadism was confirmed in this study and an impaired erectile function correlated with TT levels and infertility duration was also observed. © 2016 Blackwell Verlag GmbH.

    Erectile dysfunction (ED) is a common adverse event associated with treatment for prostate cancer. This study aimed to identify whether early, regular use of sildenafil after radiation treatment for prostate cancer is effective at reducing the rate of ED at 2 years. A randomised controlled trial with 27 men planned for radiation treatment for localised prostate cancer recruited from a single radiotherapy centre in Australia. Men were randomised to receive daily sildenafil, or a placebo tablet, for 6 months. The primary end-point was erectile function, as measured by the International Index of Erectile Function (IIEF) score, at 2-year follow-up. The abridged IIEF-5 survey was also used during the treatment period, and could be derived from the full IIEF at other time-points. Two-sided Student's t-tests and Mann–Whitney U-tests were used for the analysis of continuous outcomes, with Fisher's exact test for dichotomous outcomes. No difference was seen at 2 years in the primary end-point, and IIEF scores did not differ significantly between groups during the study. Men in the sildenafil group exhibited significantly better IIEF-5 scores at 4 weeks (P=0.02) and 6 months (P=0.02). There was no difference in erectile function scores between the two groups throughout the treatment period. No significant difference in adverse events was identified between the two groups. There was no evidence from this trial that sildenafil provides long-term erectile function for patients while on medication. Regular use of sildenafil may improve short-term sexual function for patients while on medication. Larger trials are required to examine the effectiveness of implementing sildenafil for prostate cancer patients undergoing radiation treatment.

    Full Text Available ABSTRACT Objective To investigate the effect of a 5mg daily tadalafil treatment on the ejaculation time, erectile function and lower urinary tract symptoms (LUTS in patients with erectile dysfunction. Materials and Methods A total of 60 patients diagnosed with erectile dysfunction were retrospectively evaluated using the international index of erectile function questionnaire-5 (IIEF-5, intravaginal ejaculatory latency time (IELT and international prostate symptoms scores (IPSS. After the patients were treated with 5mg tadalafil once a day for three months, their erection, ejaculation and LUTS were assessed again. The fasting levels of blood glucose, total testosterone, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and total cholesterol were measured. The independent-samples t-test was used to compare the pre- and post-treatment scores of the patients. Results The mean age of the 60 participants was 50.4±7.9 and the mean baseline serum total testosterone, total cholesterol, and fasting blood sugar were 444.6±178.6ng dL-1, 188.7±29.6mg/dL-1,104 (80-360 mg dL-1, respectively. The mean baseline scores were 2.2±1.4 min for IELT, 9.5±3.7 for IIEF-5 and 14.1±4.5 for IPSS. Following the three-month daily 5mg tadalafil treatment, the scores were found to be 3.4±1.9 min, 16.1±4.7, and 10.4±3.8 for IELT, IIEF and IPSS, respectively. When the baseline and post-treatment scores were compared, a statistically significant increase was observed in the IELTs and IIEF-5 values whereas there was a significant decrease in IPSS (p<0.01. Conclusion A daily dose of 5mg tadalafil can be safely used in the treatment of erectile dysfunction and LUTS, that prolongs the ejaculatory latency time.

    We aimed to determine whether erectile function (EF) and assessments of erection hardness correlate positively with measures of psychosocial outcomes (ie, emotional well-being, sexual satisfaction, and satisfaction with erectile dysfunction [ED] treatment) in men treated with sildenafil citrate (Viagra; Pfizer Inc, New York, NY). Data were collected from 33 worldwide phase 2, 3, and 4 sildenafil clinical trials, which included almost 10,000 men with ED. Most of these trials were randomized, double-blind, and placebo-controlled (n = 27) and were undertaken to assess doses of 50 mg adjustable to 25 mg or 100 mg, depending on efficacy and tolerability (n = 32). Doses were taken approximately 1 hour before anticipated sexual activity but not more often than once daily. EF was assessed with use of the EF domain of the International Index of Erectile Function (IIEF) and with assessments of erection hardness (Erection Hardness Grading Scale [EHGS] and IIEF Q2 [the frequency of erections hard enough for penetration]). Change (baseline to end point) in emotional well-being in men treated for ED was assessed with the Self-Esteem and Relationship (SEAR) questionnaire, which consisted of the Confidence domain (ie, the Self-Esteem subscale and Overall Relationship subscale) and the Sexual Relationship domain. End point treatment satisfaction (overall, speed of onset, and duration of action) was assessed with the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS). The IIEF was used to assess change and end point sexual satisfaction by means of the Intercourse Satisfaction domain, Q7 (frequency of satisfactory sexual intercourse), and the Overall Satisfaction domain (ie, Q13, satisfaction with sex life, and Q14, satisfaction with sexual relationship). In men treated with sildenafil for ED, scores for measures of EF (IIEF EF domain, IIEF Q2) and the percentage of erections graded completely hard and fully rigid (EHGS grade 4) correlated positively with scores for

    Full Text Available ABSTRACT Purpose The study aims to assess the influence of the stage of chronic kidney disease and glomerular filtration rate on prevalence and degree of erectile dysfunction. Materials and Methods This transversal study, conducted from May 2013 to December 2015, included patients with chronic kidney disease in conservative treatment, stages III/IV/V. Erectile dysfunction was evaluated by the International Index of Erectile Function. Data classically associated with erectile dysfunction were obtained by medical record review. Erectile dysfunction, degree of erectile dysfunction, and other main variables associated with erectile dysfunction were compared between patients with chronic kidney disease on conservative treatment stages III versus IV/V using the Chi-square test. The relationship between score of the International Index of Erectile Dysfunction and glomerular filtration rate was established by Pearson correlation coefficient. Results Two hundred and forty five patients with chronic kidney disease in conservative treatment participated of the study. The prevalence of erectile dysfunction in patients with chronic kidney disease in stages IV/V was greater than in stage III. Glomerular filtration rate positively correlated with score of the International Index of Erectile Dysfunction. Conclusions The study suggests that chronic kidney disease progression (glomerular filtration rate decrease and advance in chronic kidney disease stages worsen erectile function. Hypothetically, diagnosis and treatment of erectile dysfunction may be anticipated with the analysis of chronic kidney disease progression.

    To investigate erectile function and sexuality before/after implantation of the ATOMS device including continence outcome, pain perception and co-morbidities. We collected data from 34 patients (2010-2014) who were provided with an ATOMS implant due to mild or moderate stress urinary incontinence (SUI) after radical prostatectomy (RPE), transurethral resection (TURP) or radiotherapy. Previous failed implants were no contraindication. Sexuality was evaluated with the International Index of Erectile Function (IIEF-5). The Visual Analog Scale (VAS) and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) were used to analyse pain perception. Results regarding continence, influence of co-morbidities and drug intake were interpreted. IIEF-5 score increased 6 months after ATOMS implantation with a mean difference of 2.18 (Cl: 1.22, 3.14), p < 0,001). Non-sexually active patients had the greatest benefit. However, 50% of patients achieved a mean IIEF-5 of 10.1 and 38% of patients reported a new onset of sexual activity at follow up (mean IIEF-5 score of 12.9). This is in accordance with reduced SUI and absence of persistent pain syndrome. Overall success rate regarding 24h pad-use was 88% (no pad rate 38%). Previous failed implants did not influence results but diabetes, obesity and drug intake (beta-blockers, antidepressants) led to poorer outcomes. Sexuality and erectile function improves significantly 6 months after ATOMS implantation. We postulate that reduced SUI (also during sexual activity) and absence of chronic pain are the improving factors. ATOMS should be offered to men with mild to moderate SUI who are interested in regaining their erectile function and sexual activity.

    Brody, Stuart; Weiss, Petr

    2013-10-01

    Previous research has indicated that men generally rate slimmer women as more sexually attractive, consistent with the increased morbidity risks associated with even mild abdominal adiposity. To assess the association of women's waist size with a more tangible measure of perceived sexual attractiveness (as well as reward value for both sexes), we examined the association of women's age and waist circumference with an index of men's erectile function (IIEF-5 scores), frequency of penile-vaginal intercourse (PVI), and sexual satisfaction in a representative sample of Czechs (699 men and 715 women) aged 35-65 years. Multivariate analyses indicated that better erectile function scores were independently associated with younger age of self and partner and women's slimmer waist. PVI frequency was independently associated with women's younger age and women's slimmer waist. Sexual satisfaction was independently associated with men's younger age and slimmer waist for both sexes. Better erectile function, greater PVI frequency, and greater sexual satisfaction were associated with women's slimmer waist, independently of both sexes' ages. Possible reasons for the waist effects were discussed, including women's abdominal body fat decreasing their own desire through neurohormonal mechanisms and decreasing their partner's desire through evolutionarily-related decreased sexual attractiveness.

    We prospectively evaluated the effect of external beam radiotherapy on erectile function in patients with localized or locally advanced prostate cancer using the Japanese version of the International Index of Erectile Function (IIEF) survey. From 2000 to 2007, we identified 55 patients who underwent external beam radiotherapy at our institution for localized or locally advanced prostate cancer and could respond to the IIEF survey. The patients did not receive neo- and/or adjuvant hormone therapy and they were followed-up for at least 12 months after radiotherapy. Mean patient age was 69 years and the mean prostate specific antigen (PSA) level before radiotherapy was 24.9 ng/ml. First we evaluated the change of the erectile function domain score over time before and after radiotherapy. The population of severe erectile dysfunction (ED) increased while those with no or mild ED decreased after radiotherapy. The erectile function and intercourse satisfaction domain score of the IIEF declined significantly after radiotherapy, however, the orgasmic function, sexual desire, and overall satisfaction domain scores did not change after external beam radiation. Of the 34 patients who had erectile function at baseline, 10 patients could maintain erectile function 12 months after radiotherapy. Though there were no significant differences in clinical features between patients who could maintain erectile function and those who had worsening erectile function 12 months after radiotherapy, the sexual desire domain score before radiotherapy was significantly higher in patients who could maintain erectile function than their counterparts. Using the IIEF survey, external beam radiation was found to affect erectile function in patients with localized or locally advanced prostate cancer. (author)

    To determine the effect of Ramadan intermittent fasting on erectile function (EF), sexual desire and serum hormone levels. Eligible male participants completed the two domains of International Index of Erectile Function (IIEF) questionnaire for EF and sexual desire. They also provided information on any known disease, treatment taking, smoking habits and frequency of sexual intercourse. Frequency of sexual intercourse, two domains of IIEF questionnaire, serum hormone levels, body weight before and four-weeks after the end of month of Ramadan were also recorded. Overall, 45 men, with a mean age of 37 ± 7.2 years, participated in the study. Frequency of sexual intercourse (P = .046), sexual desire (P = .002), body weight (P = .009) and serum follicle stimulating hormone (FSH) level (P = .016) decreased significantly at the end of month of Ramadan compared to baseline. No statistically significant differences were found on EF (P = .714), serum testosterone (P = .847), luteinizing hormone (P = .876), estradiol (P = .098) and dehydroepiandrosterone sulfate levels (P = .290). Ramadan intermittent fasting might be associated with decrease in sexual desire, frequency of sexual intercourse and serum FSH level.

    As a novel therapeutic method for erectile dysfunction (ED), low-intensity extracorporeal shock wave treatment (LI-ESWT) has been applied recently in the clinical setting. We feel that a summary of the current literature and a systematic review to evaluate the therapeutic efficacy of LI-ESWT for ED would be helpful for physicians who are interested in using this modality to treat patients with ED. A systematic review of the evidence regarding LI-ESWT for patients with ED was undertaken with a meta-analysis to identify the efficacy of the treatment modality. A comprehensive search of the PubMed and Embase databases to November 2015 was performed. Studies reporting on patients with ED treated with LI-ESWT were included. The International Index of Erectile Function (IIEF) and the Erection Hardness Score (EHS) were the most commonly used tools to evaluate the therapeutic efficacy of LI-ESWT. There were 14 studies including 833 patients from 2005 to 2015. Seven studies were randomized controlled trials (RCTs); however, in these studies, the setup parameters of LI-ESWT and the protocols of treatment were variable. The meta-analysis revealed that LI-ESWT could significantly improve IIEF (mean difference: 2.00; 95% confidence interval [CI], 0.99-3.00; pwaves per treatment, and duration of LI-ESWT treatment were closely related to clinical outcome, especially regarding IIEF improvement. The number of studies of LI-ESWT for ED have increased dramatically in recent years. Most of these studies presented encouraging results, regardless of variation in LI-ESWT setup parameters or treatment protocols. These studies suggest that LI-ESWT could significantly improve the IIEF and EHS of ED patients. The publication of robust evidence from additional RCTs and longer-term follow-up would provide more confidence regarding use of LI-ESWT for ED patients. We reviewed 14 studies of men who received low-intensity extracorporeal shock wave treatment (LI-ESWT) for erectile dysfunction (ED

    Background and purpose: Erectile function (EF) is commonly affected following prostate cancer treatment. We aim to evaluate the long-term EF following seed brachytherapy (BT) treatment. Materials and methods: The study consisted of 366 patients treated with BT at our institution, who completed the IIEF-5 questionnaire and reported no or mild erectile dysfunction (ED) pre-BT. The probability of EF preservation post-BT was estimated using the Kaplan–Meier methods. The difference in EF preservation by patient-, tumour- and treatment-related factors was assessed using the log-rank test. Multivariate Cox regression was used to estimate the effect of each factor on EF preservation. Results: Of the 366 patients, 277 (76%) reported normal EF, and 89 (24%) reported mild ED. The patients were followed-up for a median of 41 months (range: 3–124), and the 5-year actuarial rate of EF preservation was 59%. Age at BT seed implant, presence of medical comorbidities, Gleason score and the biologically effective dose (BED) are associated with EF preservation (P < 0.005). The association for these four factors remains statistically significant in multivariate analysis, with Gleason score having the strongest effect (HR = 3.7; 95% CI = 2.6–5.4). Conclusion: The 5-year actuarial rate of EF preservation post-BT in our cohort is 59%, and is influenced by multiple factors

    Understanding predictors for the recovery of erectile function (EF) after nerve-sparing radical prostatectomy (nsRP) might help clinicians and patients in preoperative counseling and expectation management of EF rehabilitation strategies. To describe the effect of potential predictors on EF recovery after nsRP by post hoc decision-tree modeling of data from A Study of Tadalafil After Radical Prostatectomy (REACTT). Randomized double-blind double-dummy placebo-controlled trial in 423 men aged decision-tree models, using the International Index of Erectile Function-Erectile Function (IIEF-EF) domain score at the end of double-blind treatment, washout, and open-label treatment as response variable. Each model evaluated the association between potential predictors: presurgery IIEF domain and IIEF single-item scores, surgical approach, nerve-sparing score (NSS), and postsurgery randomized treatment group. The first decision-tree model (n=422, intention-to-treat population) identified high presurgery sexual desire (IIEF item 12: ≥3.5 and decision-tree analyses identified high presurgery sexual desire, confidence, and intercourse satisfaction as key predictors for EF recovery. Patients meeting these criteria might benefit the most from conserving surgery and early postsurgery EF rehabilitation. Strategies for improving EF after surgery should be discussed preoperatively with all patients; this information may support expectation management for functional recovery on an individual patient level. Understanding how patient characteristics and different treatment options affect the recovery of erectile function (EF) after radical surgery for prostate cancer might help physicians select the optimal treatment for their patients. This analysis of data from a clinical trial suggested that high presurgery sexual desire, sexual confidence, and intercourse satisfaction are key factors predicting EF recovery. Patients meeting these criteria might benefit the most from conserving

    Both erectile dysfunction (ED) and premature ejaculation (PE) impair the quality of sexual intercourse for both men and their female partners. This study aims to examine with a large representative sample the interrelationships of measures of ED, PE, typical intravaginal ejaculatory latency time (IELT), men's perceived relationship quality with their mother, and age of first being in love. In this cross-sectional study, a nationally representative sample of 960 Czech coitally experienced men (aged 15-84), provided age, International Index of Erectile Function 5-item (IIEF-5), Index of Premature Ejaculation (IPE) scores, IELT, rating of relationship with their mother, and age at first being in love. Correlations, partial correlations adjusting for age, analysis of covariance (ANCOVA), and multiple regression statistical methods were used. IIEF-5, IPE, and IELT were significantly intercorrelated (IIEF-5 and IPE: r=0.64). Better IIEF-5 scores were associated with younger age at first (and ever) being in love. Poorer IPE score, shorter IELT, and mild-moderate ED were associated with poorer perceived mother relationship (which was also associated with first being in love at an older age). Multiple regression analyses revealed that: (i) greater IELT was associated with better erectile function and better mother relationship, but not with age; and (ii) IELT of mother relationship and poorer IIEF-5, but marginally with age. History of homosexual activity was unrelated to IIEF-5, IPE, IELT, and perceived mother relationship scores. The findings suggest that degrees of ED and PE are often comorbid, and both ED and PE are associated with less favorable early experiences with women. Brody S and Weiss P.

    Full Text Available Erectile dysfunction (ED is a major complication after radical prostatectomy (RP; however, debate continues regarding the efficacy of penile rehabilitation in the recovery of the postoperative erectile function (EF. This study included a total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing RP, and analyzed the postoperative EF, focusing on the significance of penile rehabilitation. In this series, 24 and 79 patients underwent bilateral and unilateral nerve-sparing RPs, respectively, and 10 or 20 mg of vardenafil was administered to 35 patients at least once weekly, who agreed to undergo penile rehabilitation. Twelve months after RP, 48 (46.6% of the 103 patients were judged to have recovered EF sufficient for sexual intercourse without any assistance. The proportion of patients who recovered EF in those undergoing penile rehabilitation (60.0% was significantly greater than that in those without penile rehabilitation (38.2%. Of several parameters examined, the preoperative International Index of Erectile Function-5 (IIEF-5 score and nerve-sparing procedure were significantly associated with the postoperative EF recovery rates in patients with and without management by penile rehabilitation, respectively. Furthermore, univariate analysis identified the preoperative IIEF-5 score, nerve-sparing procedure and penile rehabilitation as significant predictors of EF recovery, among which the preoperative IIEF-5 score and nerve-sparing procedure appeared to be independently associated with EF recovery. Considering these findings, despite the lack of independent significance, penile rehabilitation with low-dose vardenafil could exert a beneficial effect on EF recovery in Japanese men following nerve-sparing RP.

    To review the role of various factors influencing vascular nitric oxide (NO) and cyclic GMP, and consequently, erectile function and vascular health. Pertinent publications are reviewed. Daily moderate exercise stimulates vascular NO production. Maintenance of normal body weight and waist/hip ratio allows NO stimulation by insulin. Decreased intake of fat, sugar, and simple carbohydrates rapidly converted to sugar reduces the adverse effects of fatty acids and sugar on endothelial NO production. Omega-3 fatty acids stimulate endothelial NO release. Antioxidants boost NO production and prevent NO breakdown. Folic acid, calcium, vitamin C, and vitamin E support the biochemical pathways leading to NO release. Cessation of smoking and avoidance of excessive alcohol preserve normal endothelial function. Moderate use of alcohol and certain proprietary supplements may favorably influence erectile and vascular function. Treatment of any remaining testosterone deficit will both increase erectile function and reduce any associated metabolic syndrome. After production of NO and cyclic GMP are improved, use of phosphodiesterase-5 inhibitors should result in greater success in treating remaining erectile dysfunction. Recent studies have also suggested positive effects of phosphodiesterase-5 inhibitors on vascular function. A multifaceted approach will maximize both erectile function and vascular health.

    Objective: The determine the frequency of erectile dysfunction in males on hemodialysis. Study Design: Descriptive study. Place and duration: Hemodialysis unit, Combined Military Hospital Kharian from October 2011 to April 2012. Patients and Methods: A total of 150 married male patients of end stage renal disease (ESRD) on hemodialysis were included in the study. Patients with cognitive and/or communication deficits and on hemodialysis for less than 06 months were excluded from the study. Erectile dysfunction (ED) was assessed using International Index of Erectile Function-5 (IIEF-5). Frequency of erectile dysfunction (ED) was analyzed using Statistical Package for Social Sciences (SPSS) version 17. Results: Mean age of the patients were 52.89 = 8.25 years. Mean duration of hemodialysis was 34 +- 9.62 months. The underlying etiology of end stage renal disease were diabetic nephropathy 69(46%), hypertensive nephropathy 51(34%), obstructive nephropathy 18(12%), glomerulonephritis 9(6%), autosomal polycystic kidney disease 3(2%). Mean IIEF-5 score was 13.29 +- 6.38. The frequency of erectile dysfunction was 74%. The majority of the patients, 73(48.7%) had moderate erectile dysfunction, while 24 (16%) had severe and 14 (9.3%) had mild erectile dysfunction. Out of total 150 patients enrolled, 39 (26%) patients had no erectile dysfunction. Conclusion: ED is a highly prevalent problem in men with ESRD. Physicians are urged to recognize the high prevalence of erection problems in men with ESRD and proactively question all patients regarding their sexual function. This will not only improve the recognition of this condition among these patients but also improve the quality of life after adequate treatment. (author)

    The recent human and animal studies indicate that the central supraspinal systems controlling penile erection, which are localized predominantly in the parts of the frontal lobe and limbic system, are reported to be involved in erection. The purpose of this study was to elucidate the correlation of the erectile dysfunction (ED) with lesions of cerebrovascular accidents (CVA). Forty-four men were selected among the CVA patients who had visited our hospital between March and July 2006. The audiovisual sexual stimulation (AVSS) test was conducted using Rigiscan device on the patients, whose erectile domain score of the International Index of Erectile Function Questionnaire (IIEF) was less than 22. The criteria for adequate erectile function was the erectile events of > 60% rigidity for > or = 5 minutes. The CVA lesions were classified into frontal lobe, cortex except frontal lobe, basal ganglia, thalamus, and other area. Each CVA lesions of ED group and non-ED group were compared. IIEF, AVSS using Rigiscan. Thirty-eight patients' erectile domain score of IIEF were less than 22, and the AVSS test was conducted on them. Eighteen patients showed no ED, and 20 patients showed ED. The mean age of the ED group was 60.40 +/- 2.2, and the mean age of non-ED group was 55.29 +/- 1.85. There was no statistically significant difference between the mean age of both groups (P = 0.081). As each CVA lesions of both groups were compared, the CVA lesions of the thalamic area in the ED group were significantly more than in the non-ED group (P = 0.010). Patients (47.4%) who were suggestive of ED in the IIEF has no ED in the AVSS test. The patients who had CVA lesions in the thalamic area more commonly showed ED than the patients with CVA lesions of any other areas.

    Erectile function is important for life satisfaction and is often impaired in men with obstructive sleep apnea (OSA). Uncontrolled studies show that treating OSA with continuous positive airway pressure (CPAP) improves erectile function. Phosphodiesterase type 5 inhibitors (e.g. vardenafil) are the first-line therapy for erectile dysfunction (ED), but may worsen OSA. To assess the effects of CPAP and vardenafil on ED. Sixty one men with moderate-to-severe OSA and ED were randomised to 12 weeks of CPAP or sham CPAP, and 10mg daily vardenafil or placebo, in a 2x2 factorial design. International Index of Erectile Function (primary endpoint), treatment and relationship satisfaction, sleep related erections, sexual function, endothelial function, arterial stiffness, quality of life, and sleep-disordered breathing. CPAP increased the frequency of sleep-related-erections, overall sexual satisfaction, and arterial stiffness but did not change erectile function or treatment satisfaction or relationship satisfaction. Vardenafil did not alter erectile function, endothelial function, arterial stiffness or sleep disordered breathing, but did improve overall self-esteem and relationship satisfaction, other aspects of sexual function and treatment satisfaction. Adherent CPAP improved erectile function, sexual desire, overall sexual, self-esteem and relationship, and treatment satisfaction, as well as sleepiness, and quality of life. Adherent vardenafil use did not consistently change nocturnal erection quality. CPAP improves overall sexual satisfaction, sleep related erections, and arterial stiffness. Low dose daily vardenafil improves certain aspects of sexual function, and did not worsen OSA. Adherent CPAP or vardenafil use further improves ED and quality of life.

    To assess whether the translated Korean version of the International Index of Erectile Function (IIEF-5) developed by Rosen et al. (RIIEF-5) may be adapted for a Korean population to have cross-cultural equivalency to the original version. A total of 151 patients with erectile dysfunction (ED) and 156 controls were prospectively studied. All the patients and controls had had sexual activity or attempted sexual intercourse within the 4-week period before completing the questionnaire. The Classification and Regression Trees program was used to select an optimal set of five items from the IIEF-15 (KIIEF-5) to discriminate between men with and without ED. Then, the optimal cutoff score for the diagnosis of ED was determined using the receiver operating characteristic curve. The optimal cutoff score, sensitivity, and specificity were also calculated using the RIIEF-5. The KIIEF-5 consisted, in order of importance, of items 15, 5, 13, 4, and 2 from the IIEF-15. Item 7 in the original RIIEF-5 was replaced with item 13 in the new KIIEF-5. The optimal cutoff score proved to be 21, with a corresponding sensitivity and specificity of 0.97 and 0.91, respectively. For the original RIIEF-5, the optimal cutoff score was 21 and the corresponding sensitivity and specificity was 0.94 and 0.90, respectively. Although the RIIEF-5 may be adapted for a Korean population, the KIIEF-5 can aid in decreasing the incidence of an incorrect diagnosis of ED and decreasing the number of undiagnosed cases of ED in this population. In addition, our findings suggest that the equivalence of psychometric properties does not imply cross-cultural equivalence.

    Most men seeking penile enhancement techniques have a normal penile size. They are either misinformed or suffer from penile dysmorphophobia and should be discouraged from undergoing invasive procedures. Less invasive techniques including penile extenders are not associated with major complications and may be beneficial from a psychological perspective. We conducted this study to assess the efficacy and safety of AndroPenis (Andromedical, Madrid, Spain) penile extender. Between December 2010 and December 2013, 163 men presented to our institution complaining of small penile length and/or girth. All patients received structured psychosexual counseling. Fifty-four patients were willing to use the AndroPenis penile extender after counseling. Patients with major psychiatric disorders were excluded from enrollment. The patients were instructed to wear the device between 4 and 6 hours per day for 6 months. Penile dimensions including flaccid stretched and erected lengths were measured at baseline and after 1, 3, 6, and 9 months. Erectile function was assessed at baseline and 9 months after treatment using the simplified International Index of Erectile Function (IIEF-5). An institutional nonstandardized questionnaire was used to evaluate patient satisfaction at the end of study. Penile length and girth enhancement as well as satisfaction rate and improvement in erectile function were assessed during follow-up. At 6-month follow-up, a mean gain of 1.7 ± 0.8, 1.3 ± 0.4, and 1.2 ± 0.4 cm was noted for the flaccid, stretched, and erected penile lengths, respectively (all P values < 0.001). During the off treatment period, there were no significant changes in penile lengths. No effect on penile girth was observed. Patient satisfaction survey revealed modest satisfaction. From 13 patients with mild baseline erectile dysfunction, nine patients reported normal erectile function after 9 months. Penile extender as a minimally invasive technique is safe and

    Erectile dysfunction can be defined as the persistent inability of man to achieve penile erection and maintain it sufficient for satisfactory coitus. The objectives of this study were to find out the impact of successful renal transplantation on the degree and frequency of erectile dysfunction. Thirty patients of end stage renal disease that were on regular haemodialysis and candidates of renal transplantation of age range 20-55 years were included in the study after getting informed consent. Erectile functions were assessed by history, examination, investigations and international index of erectile function (IIEF) before and 3 and 6 months after renal transplantation, other information regarding disease and patient were collected in the performa. Out of thirty patients 14 (46.6%) patients had sever erectile dysfunction while 16 (53.3%) patients had moderate erectile dysfunction in the pre renal transplantation period. After three months of renal transplantation 15 (50%) had severe erectile dysfunction, 6 (20%) patients moderate erectile dysfunction and 9 (30%) patients mild erectile dysfunction. After six months 11 (36.6%), 10 (33.3%) and 8 (26.6%) patients had severe, moderate and mild erectile dysfunction respectively. There was improvement in 40%, no change in 53.3% and deterioration in 6.6% patients in the erectile functions after getting renal transplantation for end stage renal disease. (author)

    There is a very high prevalence of Erectile Dysfunction (ED) in dialysis patients. There is no as such available data on ED and factors affecting it in our patients. Analytical, cross-sectional, hospital based study conducted from January to March 2008, Haemodialysis unit of Shalimar and Mayo Hospital, Lahore. All male patients of end stage renal disease (ESRD) on maintenance haemodialysis therapy, whose spouses are alive and able to perform intercourse, were included in the study. Patient with cognitive and communication deficits were excluded from study. International index of erectile function-5 (IIEF-5), adopted in Urdu was used for the determination of prevalence of erectile function. Categorization of erectile dysfunction was done as mild, moderate and severe. Demographic data were collected and certain laboratory parameters (haemoglobin, haematocrit, urea, HBsAg and Anti HCV) were sent. Total numbers of patient were fifty. Major cause of ESRD was diabetes mellitus 28 (56%). Most of the patients 33 (66%) have passed 10th grade or they were under 10th grade. Prevalence of ED was 86% with mean IIEF-5 score of 10.36+-7.13. Majority of patients 33 (64.7%) were suffering from severe degree of ED. Factors responsible for ED are diabetes mellitus, age more than 50 year, high pre dialysis urea and Anti HCV positive patients. In this study, smoking, duration of dialysis and monthly spending is not related with ED. Majority of the patients suffering from ESRD, on maintenance haemodialysis are having ED. None of the patients suffering from ED were taking any treatment for it. Haemodialysis does not improve sexual dysfunction. Major factors responsible for ED are diabetes mellitus, age more than 50 years, high pre dialysis urea and Anti HCV positive patients. (author)

    Management of adult acquired buried penis is a troublesome situation for both patient and surgeon. The buried penis has been associated with significant erectile and voiding dysfunction, depression, and overall poor quality of life (QOL). To identify outcomes following reconstructive surgery with release of buried penis, escutcheonectomy, and circumcision with or without skin grafting. We retrospectively identified 11 patients treated by a single surgeon between 2007 and 2011, patient ages were 44-69; complete data review was available on all 11. Validated European Organisation for Research and Treatment of Cancer 15 QOL, Center for Epidemiologic Studies Depression Scale (CES-D), and International Index of Erectile Function (IIEF) surveys assessed patient QOL, depression, and erectile function pre- and postoperatively. Mean body mass index (BMI) was 48.8 (42.4-64.6). Mean operative time was 191 minutes (139-272). Mean length of stay was 2.1 days. Ten of 11 patients required phallic skin grafting. There was one perioperative complication resulting in respiratory failure and overnight stay in the intensive care unit. Wound complications were seen in 2/11 patients, and 1 needed surgical debridement for superficial wound infection. Skin graft take was seen in 100% of the patients. Ninety-one percent of patients noted significant improvement in voiding postoperatively. Ninety-one percent of patients reported significant erectile dysfunction preoperatively. Subsequently, IIEF scores improved post surgery by an average of 7.7 points. Clinical depression was noted to be present in 7/11 patients preoperatively and 2/11 postoperatively based on CES-D surveys. QOL improved significantly in 10/11 compared with preoperative baseline; however, many patients noted significant difficulties based on their weight and other comorbidities. Management of adult acquired buried penis is a challenging, yet correctable problem. In our series it appears that by using established surgical

    Much attention has recently been focused on therapeutic angiogenesis as a treatment for erectile dysfunction (ED). The apelin and apelin receptor (APJ) system is known to cause endothelium-dependent vasodilatation and to be involved in angiogenesis. To examine the differential expression of apelin and APJ in animal models of vasculogenic ED and to determine whether and how enhancement of apelin-APJ signaling restores erectile function in hypercholesterolemic mice. Acute cavernous ischemia was induced in C57BL/6J mice by bilateral occlusion of internal iliac arteries, and chronic vasculogenic ED was induced by feeding a high-cholesterol diet or by intraperitoneal injection of streptozotocin. Messenger RNA (mRNA) levels of apelin and APJ were determined in cavernous tissue of each vasculogenic ED model by semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR). We evaluated erectile function by electrical stimulation of the cavernous nerve in hypercholesterolemic mice 1, 3, 7, and 14 days after a single intracavernous injection of apelin protein (5 μg/20 μL). The penis was harvested for histologic examinations and Western blot analysis. The cavernous mRNA expression of apelin and APJ was up-regulated in acute ischemia model and down-regulated in chronic vasculogenic ED models. A significant restoration of erectile function was noted 1 day after injection of apelin protein into the penis of hypercholesterolemic mice; however, erectile function returned to baseline values thereafter. The beneficial effects of apelin on erectile function resulted mainly from an activation of endothelial nitric oxide synthase and increase in nitric oxide bioavailability through reduction in reactive oxygen species-mediated endothelial apoptosis rather than through direct endothelial cell proliferation. These findings suggest that apelin-APJ signaling is a potential therapeutic target in the treatment of vasculogenic ED. Further studies are needed to develop a potent

    We evaluated the safety and efficacy of 100 and 200 mg avanafil for the treatment of adult males with erectile dysfunction after bilateral nerve sparing radical prostatectomy. This was a double-blind, placebo controlled, parallel group, phase 3 study in males age 18 to 70 years with a history of erectile dysfunction of 6 months or more after bilateral nerve sparing radical prostatectomy. Patients were randomized to 100 or 200 mg avanafil or placebo (taken 30 minutes before sexual activity) for 12 weeks. Primary end points included successful vaginal insertion (Sexual Encounter Profile [SEP] question 2), successful intercourse (SEP3) and change in score on the erectile function domain of the International Index of Erectile Function (IIEF-EF) questionnaire. A total of 298 patients were randomized and 84.6% completed the study. At baseline 16.1% were age 65 years or older and 71.5% had severe erectile dysfunction (mean overall IIEF-EF domain score 9.2). After 12 weeks there were significantly greater increases in SEP2 and SEP3 and change in mean IIEF-EF domain score with 100 and 200 mg avanafil vs placebo (p erectile function after prostatectomy. Results suggest a rapid onset of action and sustained duration of effect, with all 3 primary end points being achieved at both dose levels.

    To determine the incidence of erectile dysfunction in patients with common iliac artery (CIA) occlusive disease and the effect of revascularization on erectile function using the sexual health inventory for males (SHIM) questionnaire. All patients (35 men; mean age 57 ± 5 years; range 42–67 years) were asked to recall their sexual function before and 1 month after iliac recanalization. Univariate and multivariate analyses were performed to determine variables effecting improvement of impotence. The incidence of impotence in patients with CIA occlusion was 74% (26 of 35) preoperatively. Overall 16 (46%) of 35 patients reported improved erectile function after iliac recanalization. The rate of improvement of impotence was 61.5% (16 of 26 impotent patients). Sixteen patients (46%), including seven with normal erectile function before the procedure, had no change. Three patients (8%) reported deterioration of their sexual function, two of whom (6%) had normal erectile function before the procedure. The median SHIM score increased from 14 (range 4–25) before the procedure to 20 (range 1–25) after the procedure (P = 0.005). The type of recanalization, the age of the patients, and the length of occlusion were related to erectile function improvement in univariate analysis. However, these factors were not independent factors for improvement of erectile dysfunction in multivariate analysis (P > 0.05). Endovascular recanalization of CIA occlusions clearly improves sexual function. More than half of the patients with erectile dysfunction who underwent endovascular recanalization of the CIA experienced improvement.

    Recent studies have suggested that a relationship could exist between 25-hydroxyvitamin D [25(OH)D] deficiency and erectile dysfunction (ED). The present study evaluated the relationship between 25(OH)D levels and ED in male patients with type 2 diabetes mellitus (DM). The study included 98 patients with type 2 DM aged between 18-80 years. The International Index of Erectile Function (IIEF-5) Questionnaire was administered. The patients were divided into three groups according to IIEF-5 scoring: IIEF-5 score between 5-10, severe ED; IIEF-5 score between 11-20, moderate ED; IIEF-5 score between 21-25, no ED. Biochemical parameters, 25(OH)D and hormonal analysis tests were obtained in all patients. All parameters were compared between these three groups. Of 98 patients included in the study, 32 had severe ED, 45 had moderate ED and 21 had no ED. The mean age was 55.12 ± 9.39 years and the mean 25(OH)D level was 13.69 ± 8.15 ng/ml. When the three groups were compared, 25(OH)D levels were significantly lower in patients with the IIEF-5 score between 5-10 (p = 0.020). There was a moderate positive relationship between IIEF-5 score and 25(OH)D level (r = 0.21, p = 0.038). The patients with severe ED have considerably lower 25(OH)D levels.

    Heart rate variability (HRV) is a marker of sympathovagal balance; it has been implicated in erectile function and is also altered by tobacco use. Furthermore, smoking and erectile health are strongly related, given that smokers are at increased risk for erectile dysfunction. Few studies have explored the interrelationships between smoking, HRV, and erectile function concurrently. The aim of this study was to examine potential mechanisms underlying tobacco's effects on penile hemodynamics by exploring the mediating role of HRV. The sample comprised 119 men (smokers = 64; nonsmokers = 55) (mean age 28.90 years; standard deviation (SD) 11.68; range 18-58) selected from the control conditions of three previously published experiments. Participants were free from a history of cardiovascular disease, myocardial infarct, and/or cardiac/cardiovascular medication use. During a laboratory visit, self-report, anthropometric, cardiovascular, and electrocardiographic data were assessed, as well as sexual arousal responses elicited from viewing an erotic film. Objective sexual arousal indices (circumferential change via penile plethysmography), self-reported erectile function (per the erectile function domain score of the International Index of Erectile Function [IIEF-EF]), and time- (SD of beat-to-beat intervals) and frequency-domain parameters of HRV (ratio of low-frequency [LF] power to high-frequency [HF] power [LF/HF ratio]) were assessed. Being a current long-term cigarette smoker was associated with dysregulated sympathovagal balance (higher LF/HF ratios, indicative of sympathetic nervous system dominance), which in turn showed inverse relations with magnitude of erectile tumescence. HRV did not mediate relations between tobacco use and either IIEF-EF scores or resting penile circumference. Findings suggest that dysfunctional cardiac autonomic tone may be an underlying mechanism by which tobacco exerts its deleterious effects on erectile health. Further research

    We studied the long-term efficacy of penile low intensity shock wave treatment 2 years after an initially successful outcome. Men with a successful outcome of low intensity shock wave treatment according to the minimal clinically important difference on the IIEF-EF (International Index of Erectile Function-Erectile Function) questionnaire were followed at 6, 12, 18 and 24 months. Efficacy was assessed by the IIEF-EF. Failure during followup was defined as a decrease in the IIEF-EF below the minimal clinically important difference. We screened a total of 156 patients who underwent the same treatment protocol but participated in different clinical studies. At 1 month treatment was successful in 99 patients (63.5%). During followup a gradual decrease in efficacy was observed. The beneficial effect was maintained after 2 years in only 53 of the 99 patients (53.5%) in whom success was initially achieved. Patients with severe erectile dysfunction were prone to earlier failure than those with nonsevere erectile dysfunction. During the 2-year followup the effect of low intensity shock wave treatment was lost in all patients with diabetes who had severe erectile dysfunction at baseline. On the other hand, patients with milder forms of erectile dysfunction without diabetes had a 76% chance that the beneficial effect of low intensity shock wave treatment would be preserved after 2 years. Low intensity shock wave treatment is effective in the short term but treatment efficacy was maintained after 2 years in only half of the patients. In patients with milder forms of erectile dysfunction the beneficial effect is more likely to be preserved. Copyright © 2018 American Urological Association Education and Research, Inc.

    Tadalafil (Cialis) is an inhibitor of phosphodiesterase type 5, which mediates relaxation of vascular smooth muscle in the corpus cavernosum thus facilitating erection. The purpose of this multicentre, randomized, double-blind, parallel group, placebo-controlled study was to evaluate efficacy and treatment satisfaction of on-demand Cialis in men with mild-to-severe erectile dysfunction (ED). Following a 4-week treatment-free run in period, patients stratified into three severity groups by the International Index of Erectile Function (IIEF) Erectile Function (EF) domain score were randomized to receive either placebo or Cialis 20 mg taken on demand over a 12-week period. Efficacy endpoints were change from baseline in IIEF EF domain scores, responses to Sexual Encounter Profile diary (SEP) questions, and responses to the Global Assessment Questions (GAQ). Treatment satisfaction was evaluated using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire in two of seven participating countries where validated translations were available. Of the 443 men who entered the trial, 409 (mean age, 52 years) formed the intent-to-treat population. Mean baseline demographics and ED severity measures were balanced between treatment groups except for a higher percentage of patients naïve to sildenafil in the tadalafil group compared to placebo (50% versus 36%). The percentage of patients in each IIEF EF severity class (mild, moderate and severe) was 47%, 30% and 23% for placebo patients and 48%, 29% and 23% for tadalafil patients, respectively. Tadalafil was significantly superior to placebo on all primary efficacy measures (IIEF EF domain scores, SEP15, GAQ1; p satisfaction relative to placebo, and is well tolerated. This is the first study to yield efficacy data on tadalafil in an Eastern European population of men with erectile dysfunction, and the first to measure satisfaction with the EDITS questionnaire in any study population of men with this

    The Authors try to show the possibility to combine radical excision with minimal invasiveness in the surgery of penile cancer. The focal point of every therapeutic decision is correct clinical staging. Unfortunately there's some confusion in the two international staging systems (TNM and Jackson's classification). In fact it's not clear the anatomical difference between epithelioma of the glans infiltrating corpus spongiosum and subcoronary epithelioma of the shaft infiltrating the corpora cavernosa. It's obvious that the infiltration of the corpora cavernosa is a far more aggressive oncological manifestation than that of tumour infiltrating the corpus spongiosum. So we consider Jackson's classification more congenial. In terms of surgery this anatomical independence makes it easy to consider the corpora cavernosa as a distinct entity, so they remain perfectly functional when separated from the glandulo-spongio-urethral unit with its vasculo-nervous bundle. This makes conservation of the erectile function, when clinical staging show us that the tumour is not infiltrating the corpora cavernosa. The Authors show their results, which seem to be rather good.

    An epidemiological association between lower urinary tract symptoms and erectile dysfunction is well established. However, interactions among multiple risk factors and the role of each in pathological mechanisms are not fully elucidated We enrolled 898 men undergoing prostate cancer screening for evaluation with the International Prostate Symptom Score (I-PSS) and simplified International Index of Erectile Function-5 (IIEF-5) questionnaires. Age, race, hypertension, diabetes, dyslipidemia, metabolic syndrome, cardiovascular disease, serum hormones and anthropometric parameters were also evaluated. Risk factors for erectile dysfunction were identified by logistic regression. The 333 men with at least mild to moderate erectile dysfunction (IIEF 16 or less) were included in a latent class model to identify relationships across erectile dysfunction risk factors. Age, hypertension, diabetes, lower urinary tract symptoms and cardiovascular event were independent predictors of erectile dysfunction (pclasses of patients with erectile dysfunction (R2 entropy=0.82). Latent class 1 had younger men at low cardiovascular risk and a moderate/high prevalence of lower urinary tract symptoms. Latent class 2 had the oldest patients at moderate cardiovascular risk with an increased prevalence of lower urinary tract symptoms. Latent class 3 had men of intermediate age with the highest prevalence of cardiovascular risk factors and lower urinary tract symptoms. Erectile dysfunction severity and lower urinary tract symptoms increased from latent class 1 to 3. Risk factor interactions determined different severities of lower urinary tract symptoms and erectile dysfunction. The effect of lower urinary tract symptoms and cardiovascular risk outweighed that of age. While in the youngest patients lower urinary tract symptoms acted as a single risk factor for erectile dysfunction, the contribution of vascular disease resulted in significantly more severe dysfunction.

Prospective, randomized, double-blind and placebo-controlled study including thirty healthy men selected from 100 patients who presented themselves spontaneously complaining of erectile dysfunction, ≥ 40 years of age, nonsmokers, not undergoing treatment for prostate cancer or erectile dysfunction, no dyslipidemia, no phosphodiesterase inhibitor use, no hormonal manipulation and, if present hypertension and/or diabetes mellitus should be controlled. International Index of Erectile Function (IIEF-5) and serum testosterone were obtained before randomization and after 30 days of study. Patients were randomized into two groups of fifteen subjects each. The study group received 800 mg of Tribulus terrestris, divided into two doses per day for thirty days and the control group received placebo administered in the same way. The groups were statistically equivalent in all aspects evaluated. The mean (SD) age was 60 (9.4) and 62.9 (7.9), P = .36 for intervention and placebo groups, respectively. Before treatment, the intervention group showed mean IIEF-5 of 13.2 (5-21) and mean total testosterone 417.1 ng/dl (270.7-548.4 ng/dl); the placebo group showed mean IIEF-5 of 11.6 (6-21) and mean total testosterone 442.7 ng/dl (301-609.1 ng/dl). After treatment, the intervention group showed mean IIEF-5 of 15.3 (5-21) and mean total testosterone 409.3 ng/dl (216.9-760.8 ng/dl); the placebo group showed mean IIEF-5 of 13.7 (6-21) and mean total testosterone 466.3 ng/dl (264.3-934.3 ng/dl). The time factor caused statistically significant changes in both groups for IIEF-5 only (P = .0004), however, there was no difference between the two groups (P = .7914).

    The relationship between erectile dysfunction (ED) and chronic renal failure (CRF) has been reported in several studies. This study aimed to investigate whether the chronic use of sildenafil could enhance the erectile capacity in CRF-induced rats. In addition, we assessed the effect of that treatment on certain molecules, which have been suggested to play crucial roles in erectile physiology and CRF-related ED as well. Three groups of animals were utilized: (1) age-matched control rats, (2) CRF-induced rats, (3) CRF-induced rats treated with chronic administration of sildenafil (5 mg kg−1 p.o. for 6 weeks [treatment started after 6 weeks of CRF induction]). At 3 months, all animals underwent cavernosal nerve stimulation (CNS) to assess erectile function. Penile tissue advanced glycation end products (AGE's)/5-hydroxymethyl-2-furaldehyde, malondialdehyde (MDA), cGMP (ELISA), inducible nitric oxide synthase (iNOS) and neuronal NOS (nNOS) (Western blot) analyses were performed in all rat groups.

    Full Text Available Erectile dysfunction (ED is considered a condition with a broad range of etiologies. Obstructive sleep apnea (OSA syndrome is one of the lesser studied risk factors for ED. We intend to summarize the current evidence on the relationship between OSA and sexual impairment, focusing on the results in terms of erectile function of the different therapies offered to OSA patients. A systematic review was conducted, selecting articles related to the physiology of OSA and ED, and to the treatments of OSA syndrome and their reported outcomes in erectile and sexual function. Higher prevalences of ED in the OSA groups have been published. However, whether this effect on the erectile function occurs in the entire range of OSA severities remains unclear. Several hypotheses were proposed to explain the physiology of this association. Continuous Positive Airway Pressure as a treatment for OSA patients with ED has achieved a significative improvement in the sexual parameters in most of the studies. Phosphodiesterase type 5 inhibitors (iPDE5 on demand are useful as a treatment for ED in this subgroup of patients, with high satisfaction rates. The surgical treatment for the OSA evidenced benefits over the erectile function, and the effect on the sexual satisfaction of the therapy using Mandibular Advancement Devices is still undefined.

    Short-term data on the effect of low-intensity extracorporeal shockwave therapy (Li-ESWT) on erectile dysfunction (ED) have been inconsistent. The suggested mechanisms of action of Li-ESWT on ED include stimulation of cell proliferation, tissue regeneration, and angiogenesis, which can be processes with a long generation time. Therefore, long-term data on the effect of Li-ESWT on ED are strongly warranted. To assess the outcome at 6 and 12 months of linear Li-ESWT on ED from a previously published randomized, double-blinded, sham-controlled trial. Subjects with ED (N = 126) who scored lower than 25 points in the erectile function domain of the International Index of Erectile Function (IIEF-EF) were eligible for the study. They were allocated to 1 of 2 groups: 5 weekly sessions of sham treatment (group A) or linear Li-ESWT (group B). After a 4-week break, the 2 groups received active treatment once a week for 5 weeks. At baseline and 6 and 12 months, subjects were evaluated by the IIEF-EF, the Erectile Hardness Scale (EHS), and the Sexual Quality of Life in Men. The primary outcome measure was an increase of at least 5 points in the IIEF-EF (ΔIIEF-EF score). The secondary outcome measure was an increase in the EHS score to at least 3 in men with a score no higher than 2 at baseline. Data were analyzed by linear and logistic regressions. Linear regression of the ΔIIEF-EF score from baseline to 12 months included 95 patients (dropout rate = 25%). Adjusted for the IIEF-EF score at baseline, the difference between groups B and A was -1.30 (95% CI = -4.37 to 1.77, P = .4). The success rate based on the main outcome parameter (ΔIIEF-EF score ≥ 5) was 54% in group A vs 47% in group B (odds ratio = 0.67, P = .28). Improvement based on changes in the EHS score in groups A and B was 34% and 24%, respectively (odds ratio = 0.47, P = .82). Exposure to 2 cycles of linear Li-ESWT for ED is not superior to 1 cycle at 6- and 12-month follow-ups. Fojecki GL, Tiessen S

    Sexual dysfunction is frequent in the diabetic population. In Africa, medical care for erectile dysfunction is underprovided, profoundly altering the quality of life of the patients. We report the prevalence of erectile dysfunction in 187 diabetic patients followed in the department of Endocrinology of the Conakry teaching hospital. Prevalence was estimated from the French version of the International Index of Erectile Function (IIEF). Erectile dysfunction concerned 90 patients (48%) of whom a severe form was observed in 54%, a moderate form in 35% and a mild form in 12%. The patients who presented erectile dysfunction were significantly older, displayed longer duration of diabetes with more complications (sensorial neuropathy and macroangiopathy) and often took drugs for associated cardiovascular diseases. In 28% of the cases, erectile dysfunction was associated with a decline in libido and in 26% with ejaculation disorders. In conclusion, erectile dysfunction is frequent and severe among diabetic patients in Guinea. The medical staff plays an essential role to initiate early diagnosis, promote psychological support and provide medication, if possible.

    To estimate the prevalence of erectile dysfunction (ED) and the level of psychological distress and to assess the inter-associations of them among type 2 diabetic men, a cross-sectional observational study of 335 men with type 2 diabetes and 284 men without diabetes from a hospital in Hefei city, Anhui province, China, was conducted. The erectile function was assessed using the five-item version of the International Index of Erectile Function scale (IIEF-5). The evaluation of psychological distress was completed using a self-administered questionnaire, the Symptom Checklist 90-Revised (SCL-90-R). In this study, ED was more prevalent in type 2 diabetic men than that in the control group (58.51% vs 26.76%, Ppsychological distress were strongly correlated in type 2 diabetic patients. Clinicians should be aware of the association between ED and psychological distress when treating men with type 2 diabetes.

    Erectile dysfunction (ED) has been associated with several comorbidities and can cause significant loss of quality of life and self-esteem. In men with ED, to use the validated Self-Esteem and Relationship (SEAR) questionnaire to evaluate changes in self-esteem associated with sildenafil treatment of ED and to assess changes dependent on concomitant comorbid conditions. This was a 14-week, international, randomized, parallel-group, double-blind, flexible-dose (25, 50, or 100 mg), placebo-controlled study of sildenafil in men aged >or=18 years with a clinical diagnosis of ED (score Erectile Function (IIEF) domain scores and in the intercourse success rate, and the response to the global efficacy assessment and to the global satisfaction assessment. A total of 841 patients were included in the intent-to-treat efficacy analysis (559 sildenafil, 282 placebo). Patients randomized to sildenafil had significantly greater change scores from baseline to the end of treatment on all components of the SEAR and all domains of the IIEF (P Erectile Function domain score (r = 0.6338, P emotional benefits of sildenafil in the treatment of ED were confirmed, overall and in men with comorbid hypertension, hyperlipidemia, benign prostatic hypertrophy, and/or depression. Using both the IIEF and the SEAR questionnaires provides a more complete assessment of ED.

    2009-09-01

    Full Text Available To examine the effect of sildenafil on erectile dysfunction (ED and psychosocial outcomes in alcohol-dependent (AD men, 108 men with these diagnoses were randomly assigned to either take sildenafil (50 mg as add-on to standard treatment for AD, or the same treatment without sildenafil, for 12 weeks. Only 50 patients in sildenafil group and 51 in control group twice completed the International Index of Erectile Function (IIEF and a battery of self-report questionnaires. IIEF scores and psychosocial functioning, self-esteem and support from friends improved only for sildenafil-treated patients (P < 0.001. The high effect sizes suggest that the observed benefits are unlikely to be a placebo effect, although their unspecific nature could not be ruled out. In men with ED associated with AD, sildenafil improves both ED and psychosocial outcomes. Further placebo-controlled clinical trial is warranted.

    Full Text Available Background: This study investigated the correlation between epicardial adipose tissue (EAT, a measure of central obesity, and sexual function in males with vasculogenic erectile dysfunction (ED. Materials and Methods: The study was a cross-sectional study of selected males with ED aged <75 years who attended the Urology Outpatient Department of Tri-Service General Hospital. Sixty subjects were included in the study, which employed biochemical data, anthropometric indexes, echocardiography, and questionnaires. Biochemical lipid profiles and associated inflammation markers were recorded. The anthropometric indexes included general and central obesity and bioelectrical impedance analysis. Echocardiography results were assessed by a single experienced cardiologist and included epicardial and pericardial fat thickness measurements. Sexual function was evaluated using the International Index of Erectile Function-5 (IIEF-5 score. Results: According to the analysis of variance and multivariate logistic regression, only the erectile hardness score (EHS was statistically positively correlated with the IIEF-5 score. All other anthropometric indexes and echocardiography parameters, including EAT thickness, pericardial adipose tissue thickness, and ejection fraction (EF, were not significantly associated with sexual function. Conclusions: Only EHS was statistically associated with sexual function in the male subjects with ED. The anthropometric indexes and EAT thickness, a measure of central obesity, were not significantly correlated with sexual function in the male patients with ED.

    Purpose: The results of a 1997 meta-analysis of the rates of erectile function after external beam radiotherapy (EBRT) and radical prostatectomy have been widely used in patient and professional education materials and as a reference against which new findings are compared. With a number of recent publications, it is now possible to update this analysis and compare brachytherapy with or without EBRT with EBRT alone, standard and nerve-sparing radical prostatectomy, and cryotherapy. Methods: A comprehensive literature review and subsequent meta-analysis of the rates of erectile dysfunction associated with the treatments of localized prostate carcinoma was conducted. A simple logistic regression analysis was used to combine the data from the 54 articles that met the selection criteria. Results: The predicted probability of maintaining erectile function after brachytherapy was 0.76, after brachytherapy plus EBRT 0.60, after EBRT 0.55, after nerve-sparing radical prostatectomy 0.34, after standard radical prostatectomy 0.25, and after cryotherapy 0.13. When only studies reporting ≥2 years follow-up were considered, the only significant change was a decline in the probability for nerve-sparing radical prostatectomy. No brachytherapy studies had a follow-up of ≥2 years. When the probabilities were adjusted for age, the spread between the RT methods and surgical approaches was greater. Conclusion: The differences in the probability of maintaining erectile function after different treatments of localized prostate cancer are significant

    Purpose: To determine the efficacy of sildenafil citrate (Viagra) in patients with erectile dysfunction after three-dimensional conformal external beam radiotherapy (3D-CRT) for prostate cancer. Methods and Materials: 406 patients with complaints of erectile dysfunction and who completed radiation at least 6 months before the study were approached by mail. 3D-CRT had been delivered (mean dose 68 Gy). Sixty patients were included and entered a double-blind, placebo-controlled, cross-over study lasting 12 weeks. They received during 2 weeks 50 mg of sildenafil or placebo; at Week 2 the dose was increased to 100 mg in case of unsatisfactory erectile response. At Week 6, patients crossed over to the alternative treatment. Data were collected using the International Index of Erectile Function (IIEF) questionnaire, and side effects were recorded. Results: Mean age was 68 years. All patients completed the study. For most questions of the IIEF questionnaire there was a significant increase in mean scores from baseline with sildenafil, but not with placebo. Ninety percent of the patients needed a dose adjustment to 100 mg sildenafil. Side effects were mild or moderate. Conclusion: Sildenafil is well tolerated and effective in improving erectile function of patients with ED after 3D-CRT for prostate cancer

    Erectile dysfunction is a common disease characterized by endothelial dysfunction. The aetiology of ED is often multifactorial but evidence is being accumulated in favor of the proper function of the vascular endothelium that is essential to achieving and maintaining penile erection. Uric acid itself causes endothelial dysfunction via decreased nitric oxide production. This study aims to evaluate the serum uric acid (SUA) levels in 180 ED patients, diagnosed with the International Index of Erectile Function-5 (IIEF-5) and 30 non-ED control. Serum uric acid was analyzed with a commercially available kit using ModularEVO (Roche, Monza, Italy). Within-assay and between-assay variations were 3.0% and 6.0%, respectively. Out of the ED patients, 85 were classified as arteriogenic (A-ED) and 95 as non-arteriogenic (NA-ED) with penile-echo-color-Doppler. Uric acid levels (median and range in mg/dL) in A-ED patients (5.8, 4.3-7.5) were significantly higher (p uric acid levels in patients with mild A-ED (IIEF-5 16-20) and severe/complete A-ED (IIEF-5 ≤ 10) that were 5.4 (range 4.3-6.5) mg/dL and 6.8 (range 6.4-7.2) mg/dL, respectively. There was no difference between the levels of uric acid in patients with different degree of NA-ED. Our findings reveal that SUA is a marker of ED but only of ED of arteriogenic aetiology.

    To measure the impact of psychotherapy associated to the use of Tadalafil in the improvement of erectile function after radical prostatectomy. From 132 patients surgically treated for prostate cancer, thirty sequential patients with bilateral nerve sparing, low risk controlled disease and post-surgery erectile dysfunction (ED) took Tadalafil 20mg and underwent psychotherapy sessions, both weekly for three months. Patients were interviewed to establish the quality of erection using the instrument IIEF-5 and to measure psychological features impacting erectile function, aspects related to function, dysfunction, physical and emotional discomfort were evaluated with the help of an intensity scale. The average age was 62.5 (46 to 77 years), 96.7% had a stable relationship, 56.6% of the patients accepted the diagnosis and 43.2% exhibited defense mechanisms (3.3% negation, 6.6% revulsion, 33.3% concern). A positive correlation was observed between erectile function and time exposed to treatment (IIEF-5 - 9.7 to 13.3, p=0.0006), with increased satisfaction with life in general (2.1 to 2.7, P=.028) and sexual life (3.1 to 3.7, P=.028), added to facilitation of expressing feelings/emotions (1.8 to 3.0, P=.0008). Satisfaction with relationship and intimacy with partner did not present significant improve (P=.12 and P=.61, respectively). A holistic patient care with more complete ED rehabilitation includes psychotherapy with a positive correlation between erectile function and treatment exposition. Psychotherapy allowed the identification of important spouse related factors in this scenario. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Evidence is lacking for multi-ingredient herbal supplements claiming therapeutic effect in sexual dysfunction in men. We examined the safety and efficacy of VigRX Plus (VXP) - a proprietary polyherbal preparation for improving male sexual function, in a double blind, randomized placebo-controlled, parallel groups, multi-centre study. 78 men aged 25-50 years of age; suffering from mild to moderate erectile dysfunction (ED), participated in this study. Subjects were randomized to receive VXP or placebo at a dose of two capsules twice daily for 12 weeks. The international index of erectile function (IIEF) was the primary outcome measure of efficacy. Other efficacy measures were: Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), Serum testosterone, Semen analysis, Investigator's Global assessment and Subjects' opinion. In subjects receiving VXP, the IIEF-Erectile Function (EF) scores improved significantly as compared to placebo. After 12 weeks of treatment, the mean (sd) IIEF-EF score at baseline increased from 16.08 (2.87) to 25.08 (4.56) in the VXP group versus 15.86 (3.24) to 16.47 (4.25) in the placebo group (P sexual desire, intercourse satisfaction, and overall satisfaction).There was a significant difference for VXP versus placebo comparison of mean (sd) EDITS scores of patients: 82.31(20.23) vs 36.78(22.53) and partners :(82.75(9.8) vs 18.50(9.44);P global assessment rated VXP therapy as very good to excellent in more than 50% patients and placebo therapy as fair to good in about 25% of patients. Incidence of side effects and subject's rating for tolerability of treatment was similar in both groups. VigRX Plus was well tolerated and more effective than placebo in improving sexual function in men. Clinical Trial Registry India, CTRI/2009/091/000099, 31-03-2009.

    Treating cancer patients, sexual issues should not be forgotten. With increasing survival from urologic cancer, quality of life and quality of sexuality have became very important targets in treating those patients. Fertility to those patients who desire fatherhood is sometimes more important than cancer morbidity, especially young patients in the rural areas in our country, to the extent that they may refuse the operation. We describe a new technique to preserve the erectile function and antegrade ejaculation after radical cystectomy. Patients and Methods: Seven potent men with a median age of 40 years (range 35-50) presented with invasive transitional cell carcinoma (TCC) of the lateral or the anterior bladder wall. All patients wished to preserve the ejaculatory function and fertility potential. We described the surgical technique of nerve sparing radical cystectomy with preservation of the vas deferens, seminal vesicles, whole prostate and neurovascular bundles. The follow up period ranged from six months to three years (mean 20 months) to assess recurrence, erectile function and ejaculatory function. Erectile function is normal in all patients with satisfactory sexual intercourse. Antegrade ejaculation was documented in six cases. One of them fathered a child. No local or distant recurrence was detected in the seven patients at the last follow-up. The technique of radical cystectomy (with preservation of the vas deferens, whole prostate and seminal vesicle) is a good option in selected young men with bladder carcinoma in whom preservation of fertility is desirable

    Dissection of the cavernous nerves eliminates spontaneous erections. We evaluated the ability of Schwann cell seeded nerve guidance tubes to restore erections after bilateral cavernous nerve resection in rats. Sections (5 mm) of the cavernous nerve were excised bilaterally, followed by immediate bilateral microsurgical reconstruction. In 10 animals per group (20 study nerves) reconstruction was performed by genitofemoral nerve interposition, interposition of silicone tubes or interposition of silicone tubes seeded with homologous Schwann cells. As the control 10 animals (20 study nerves) underwent sham operation (positive control) and bilateral nerve ablation (without reconstruction) was performed in a further 10 (negative control). Erectile function was evaluated 3 months postoperatively by relaparotomy, electrical nerve stimulation and intracavernous pressure recording. After 3 months neurostimulation resulted in an intact erectile response in 90% (18 of 20) of Schwann cell grafts, while treatment with autologous nerves (30% or 6 of 20) or tubes only (50% or 10 of 20) was less successful (p Schwann cell grafts compared to results in the other treatment groups (p Schwann cell grafts. Schwann cell seeded guidance tubes restore erectile function after the ablation of cavernous nerves in rats and they are superior to autologous nerve grafts.

    Full Text Available Testosterone is overwhelmingly important in regulating erectile physiology. However, the associated molecular mechanisms are poorly understood. The purpose of this study was to explore the effects and mechanisms of testosterone in erectile dysfunction (ED in castrated rats. Forty male Sprague-Dawley rats were randomized to four groups (control, sham-operated, castration and castration-with-testosterone-replacement. Reactive oxygen species (ROS production was measured by dihydroethidium (DHE staining. Erectile function was assessed by the recording of intracavernous pressure (ICP and mean arterial blood pressure (MAP. Protein expression levels were examined by western blotting. We found that castration reduced erectile function and that testosterone restored it. Nitric oxide synthase (NOS activity was decrease in the castrated rats, and testosterone administration attenuated this decrease (each p < 0.05. The testosterone, dihydrotestosterone, cyclic guanosine monophosphate (cGMP and cyclic adenosine monophosphate (cAMP concentrations were lower in the castrated rats, and testosterone restored these levels (each p < 0.05. Furthermore, the cyclooxygenase-2 (COX-2 and prostacyclin synthase (PTGIS expression levels and phospho-endothelial nitric oxide synthase (p-eNOS, Ser1177/endothelial nitric oxide synthase (eNOS ratio were reduced in the castrated rats compared with the controls (each p < 0.05. In addition, the p40phox and p67phox expression levels were increased in the castrated rats, and testosterone reversed these changes (each p < 0.05. Overall, our results demonstrate that testosterone ameliorates ED after castration by reducing ROS production and increasing the activity of the eNOS/cGMP and COX-2/PTGIS/cAMP signaling pathways.

    Full Text Available Background/Aim. During the first 10 years over 50% of diabetes patients develop erectile dysfunction (ED. It is more severe and resistant to therapy than in male patients with normal glucoregulation. The purpose of this pilot study was to estimate the tadalafil (Cialis efficacy and safety in male patients with diabetes mellitus (DM, together with moderate to severe ED. Methods. The study included 30 male patients with diagnozed type 1 or type 2 DM together with ED. ED was estimated through the International Index of Erectile Function (IIEF-6, Sexual Encounter Profile (SEP questionnaire and prostaglandin test, at the beginning of the research and three months after the 20 mg tadalafil therapy initiation, once a week (on Fridays. Glycosylated haemoglobin in blood (HbA1c values were also monitored. According to the ED severity (IIEF values at the beginning of the therapy the patients were divided into 2 groups. The previous experience with sildenafil citrate (Viagra and prostaglandin E1 intracavernous therapy was recorded. Results. Tadalafil significantly improved ED (p < 0.001 for 7.40 points of the IIEF score, i.e. for 58% and 60% towards SEP2 and SEP3 questionnaire, respectively. Compared to the previous ED therapy subjectively better tadalafil experience was recorded. Each group experienced a significant improvement in IIEF score (p < 0.001, more significantly in the group 2 (8.26±1.49 points compared with the medium improvement in the group 1 (6.27±1.35 points. After three months HbA1c values decreased for 2.26±1.62 (p < 0.001. Conclusion. Tadalafil is an effective tool for treating ED in diabetes patients. In some situations tadalafil application could replace prostaglandin test. The sexual sphere motivation leads to the improvement of glucoregulation in DM patients. .

    2015-01-01

    Background: Among diabetic patients autonomic neuropathy (AN) is one of the most frequent complications. This affects peripheral nervous system and thus results into erectile dysfunction (ED). The main objectives of the study were to determine the frequency of autonomic neuropathy (AN) in diabetic patients with ED and to find out the associated risk factors. Method: In this descriptive case series, a total 200 consecutive patients of Diabetes Mellitus with erectile dysfunction attended the Department of Endocrinology and Metabolism (DEM), Services Hospital Lahore during three months (from June to August 2013), were included. For assessing erectile dysfunction (ED) and autonomic neuropathy (AN) International Index of Erectile Function (IIEF) and Composite Autonomic Scoring System (CASS) were used respectively. Other factors impacting the autonomic functions in diabetes like duration of diabetes, age of patient, body mass index (BMI), and glycaemic control (HbAlc), hypertension and smoking status were recorded. Results: Average age of the patients was 57.58±9.53 years (95 percentage C.I. 55.54-59.63). Frequency of autonomic neuropathy (AN) in ED patients was 86 (43 percentage). Duration of diabetes Mellitus and BMI were statistically significantly different among patients with severe, moderate and mild autonomic neuropathy. Conclusions: Autonomic neuropathy was very frequent in diabetic patients with erectile dysfunction. The associated risk factors are duration of disease and body mass index. (author)

    2002-01-01

    Purpose: The advent of widespread prostate-specific antigen screening has resulted in more younger, potent men being diagnosed with early-stage, organ-confined prostate cancer amenable to definitive surgery. Nerve-sparing prostatectomy is a relatively new surgical advance in the treatment of prostate cancer. Very few data exist on the effect of postoperative radiotherapy (RT) on erectile function after nerve-sparing prostatectomy. They are based on conventional techniques using moderate doses of radiation, 45-54 Gy. Intensity-modulated RT (IMRT) is becoming more widespread because it allows dose escalation with increased sparing of the surrounding normal tissue. We investigated the effect of postprostatectomy, high-dose IMRT on patients' erectile function. Methods and Materials: A review of patient records found 51 patients treated between April 1998 and December 2000 with IMRT after unilateral or bilateral nerve-sparing prostatectomy. The pathologic disease stage in these patients was T2 in 47.4% and T3 in 52.6%. Postoperatively, 4 patients received hormonal ablation consisting of one injection of Lupron Depot (30 mg) 2 months before RT. The median age was 65 years (range 46-77) at the time of RT. The prescribed dose was 64 Gy (range 60-66). The mean dose was 69.6 Gy (range 64.0-72.3). Erectile function was assessed before and after RT by questionnaires. Sexual potency was defined as erectile rigidity adequate for vaginal penetration. Results: Of the 51 patients, 18 (35.3%) maintained their potency and 33 (64.7%) became impotent after nerve-sparing prostatectomy. Patients who underwent bilateral nerve-sparing prostatectomy had higher rates of postoperative potency than did those who underwent unilateral nerve-sparing surgery (72.2% vs. 27.8%; p=0.025). The follow-up for the entire group was 19.5 months. All 18 patients (100%) who were potent postoperatively remained potent after RT. The median follow-up for the 18 potent patients was 27.2 months, significantly

    Full Text Available We aim to investigate the correlations between hemodynamic parameters, penile rigidity grading, and the therapeutic effects of phosphodiesterase type 5 inhibitors using color Doppler flow imaging after intracavernosal injection in patients with erectile dysfunction. This study involved 164 patients. After intracavernosal injection with a mixture of papaverine (60 mg, prostaglandin E 1 (10 mg, and lidocaine (2%, 0.5-1 ml, the penile vessels were assessed using color Doppler flow imaging. Penile rigidity was classified based on the Erection Hardness Score system as Grades 4, 3, 2 or 1 (corresponding to Schramek Grades V to II. Then, the patients were given oral sildenafil (50-100 mg and scored according to the International Index of Erectile Function (IIEF-5 questionnaire. The number of patients with penile rigidities of Schramek Grades II to V was 14, 18, 21, and 111, respectively. The IIEF-5 score was positively correlated with the refilling index of the penile cavernosal artery (r = 0.79, P< 0.05, the peak systolic velocity (r = 0.45, P< 0.05, and penile rigidity (r = 0.75, P< 0.05, and was negatively correlated with the end diastolic velocity (r = −0.74, P< 0.05. For patients with erectile dysfunction, both the IIEF-5 score after sildenafil administration, which is correlated with penile rigidity, and the hemodynamic parameters detected using color Doppler flow imaging may predict the effects of phosphodiesterase type 5 inhibitor treatment and could provide a reasonable model for the targeted-treatment of erectile dysfunction.

    Full Text Available Objectives: In recent years, it has been shown that there is association between metabolic syndrome and urinary stone disease. Stone disease and erectile dysfunction (ED are considered as systemic diseases which are associated with hormonal and metabolic disorders. Therefore we investigated the relationship between ED and urinary tract calculi. Material and methods: 98 male patients with urolithiasis and 59 randomly selected male patients without stone disease were included in the study. Serum testosterone (T levels were measured and International Index of Erectile Function (IIEF-15 questionnaire forms were used to assess ED. Results: The prevalence of ED was found 29% (29 patients in the urolithiasis group. Sixty-nine patients (71% had no ED; 16 (16.3% had mild, 5 (5.1% had moderate and 8 (8.2% had severe ED. None of the patients in the control group had severe or modarete ED, six patients (10.2% had mild ED. Serum T levels were detected at the level of biochemical hypogonadism on 13 patients with stones (13.3% and T levels were detected at the lower limit in 18 (18.3% patients. Conclusion: In our study we have shown that ED and low T levels are significantly associated with urolithiasis. We propose that the patients with urolitiasis should be evaluated for ED and hypogonadism.

    Full Text Available Background: Methadone is considered a long-acting opioid agonist which is widely used in the treatment of drug addiction. It is believed that opioids can cause erectile dysfunction (ED by inhibiting gonadotropin and testosterone release. This study is aimed at defining the possible effects of conservative treatment with methadone on erectile dysfunction in the addicts. Methods: A total of 382 male addicts visiting methadone maintenance therapy (MMT centers in Rasht, Iran, during 2010 were enrolled in this study. International Index of Erectile Function (IIEF questionnaire and patients' profiles were the main means of collecting data on demographic information, methadone dose intake, and erectile function status before and after the two months of therapy with methadone. Erectile function status was defined by the total score from questions 1, 2, 3, 4, 5, and 15 of the questionnaire. The data was analyzed by X2, McNemer’s test, and paired t-test using SPSS software 18. Results: The mean age of patients was 37.6 ± 8.9 years (range: 18-72 years. Most of the patients were married (79.3% and they were citizens of Rasht (72.3%. The most frequent substances were opium (188 patients, 49.2% and crack (129 patients, 33.8%, respectively. Most of the patients received low dose methadone (286 patients, 74.9%. No significant relationship was indicated comparing the average scores of erectile function before and after taking methadone (18.53±6.978 vs. 19.03±5.819 (P=0.138. However, the severity of erectile dysfunction was significantly related to the methadone intake dose (P<0.001. Conclusion: Although MMT increases the frequency of erectile dysfunction, appropriate doses of methadone minimize this effect.

    Full Text Available This study is aimed to determine the correlation between fasting glucose level, erectile dysfunction,and lower urinary tract symptoms (LUTS in patients diagnosed with benign prostatic hyperplasia (BPH. Weenrolled patients with BPH-related LUTS aged over 50 years old. LUTS and erectile dysfunction (ED wereevaluated using International Prostate Symptom Score (IPSS and International Index of Erectile Function-5(IIEF-5. Diabetes mellitus was established if fasting glucose level was above 126mg/dL. Forty-two patientswere enrolled in this study from outpatient clinic in Kardinah Hospital, Tegal during January–March 2015.Patients’ mean age was 68.8±8.6 years old with most of them suffered from ED (83.3% and also suffered fromsevere LUTS (80.96%. Mean fasting glucose level was 108.3 + 21.1 mg/dl. However, diabetes mellitus wasobserved in 26.2% subjects with mean fasting glucose level was 136.8+7.8mg/dl. IPSS score was correlatedwith fasting glucose level (r=0.879, p<0.001 and IIEF-5 score (r= -0.346, p=0.025. IIEF-5 score showednegative correlation with age (r=-0.31, p=0.046 and fasting glucose level (r=-0.305, p=0.049. Higher fastingglucose level in a man older than 50 years with BPH would increase severity of LUTS and ED.

    Chronic prostatitis (CP) significantly worsens a patient's quality of life (QOL), but its etiology is heterogeneous. Although the inflammatory process must be associated with CP symptoms, not all patients with benign prostatic hyperplasia and histological prostatitis complain of CP symptoms. The relation between the severity of histological inflammation and lower urinary tract symptoms (LUTS) and erectile function is not fully understood. This study comprised 26 men with suspected prostate cancer but with no malignant lesion by pathological examination of prostate biopsy specimens. LUTS were assessed by several questionnaires including the International Prostate Symptom Score (IPSS), QOL index, Overactive Bladder Symptom Score (OABSS), and the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and erectile function was assessed by the Sexual Health Inventory for Men. Prostate volume (PV) measured by transabdominal ultrasound, maximum flow rate by uroflowmetry, and serum concentration of prostate-specific antigen were also evaluated. All data collections were performed before prostate biopsy. Histological prostatitis was assessed by immunohistochemical staining with anti-CD45 antibody as the Quick score. The relation between the Quick score and several factors was assessed by Pearson correlation coefficient and a multivariate linear regression model after adjustment for PV. The Pearson correlation coefficient showed a correlation between the Quick score and several factors including PV, IPSS, QOL index, OABSS, and NIH-CPSI. A multivariate linear regression model after adjustment for PV showed only the NIH-CPSI to be associated with the Quick score. The relation between the Quick score and each domain score of the NIH-CPSI showed only the subscore of urinary symptoms to be an associated factor. We found a correlation only between histological prostatitis and LUTS, but not erectile dysfunction. Especially, the subscore of urinary symptoms

    Erectile dysfunction (ED) affects about 50% of males aged 40-70 years old. ED shares with atherosclerotic disease several common risk factors; therefore, it may be considered a surrogate marker of atherosclerosis. Since phosphodiesterase-5 inhibitors are well known pharmacologic agents capable of significant improvement in ED, we designed this study to evaluate whether exercise training is of added value in patients with ED who are already on PDE-5 inhibitors. We recruited 20 male patients affected by ED with metabolic syndrome. At baseline, all patients underwent Cardio-Pulmonary Exercise Testing (CPET) and the International Index of Erectile Function (IIEF) test. After the initial evaluation, patients were subdivided into two groups: tadalafil group (group T, n = 10), who were maintained only on tadalafil therapy, and a tadalafil/exercise training group (T/E group, n = 10) who continued tadalafil but in addition underwent a2-month structured exercise training program. Basal anthropometric characteristics of study population showed no significant differences. Although both-groups showed at 2 months an improvement of the IIEF score, this was more evident in the T/E group (T group: 11.2 vs 14.2, P = 0.02; T/E group: 10.8 vs 20.1, P exercise (VO(2peak)) only in the T/E group patients (T group: 13.63 +/- 2.03 vs 14.24 +/- 2.98 mL/kg/min; P = 0.521; T/E group: 13.41 +/- 2.97 vs 16.58 +/- 3.17 mL/kg/min; P = 0.006). A significant correlation was found between the changes in VO(2peak) and the modifications in IIEF score (r = 0.575; P = 0.001). Exercise training in ED patients treated with PDE-5 inhibitors is of added value since further improves ED, as evaluated by IIEF score, and increases functional capacity.

    Full Text Available Androgen deficiency is strongly associated with erectile dysfunction (ED. Inadequate penile arterial blood flow is one of the major causes of ED. The blood flow to the corpus cavernosum is mainly derived from the internal pudendal arteries (IPAs; however, no study has evaluated the effects of androgen deprivation on IPA′s function. We hypothesized that castration impairs IPAs reactivity and structure, contributing to ED. In our study, Wistar male rats, 8-week-old, were castrated and studied 30 days after orchiectomy. Functional and structural properties of rat IPAs were determined using wire and pressure myograph systems, respectively. Protein expression was determined by Western blot and immunohistochemistry. Plasma testosterone levels were determined using the IMMULITE 1000 Immunoassay System. Castrated rats exhibited impaired erectile function, represented by decreased intracavernosal pressure/mean arterial pressure ratio. IPAs from castrated rats exhibited decreased phenylephrine- and electrical field stimulation (EFS-induced contraction and decreased acetylcholine- and EFS-induced vasodilatation. IPAs from castrated rats exhibited decreased internal diameter, external diameter, thickness of the arterial wall, and cross-sectional area. Castration decreased nNOS and α-actin expression and increased collagen expression, p38 (Thr180/Tyr182 phosphorylation, as well as caspase 3 cleavage. In conclusion, androgen deficiency is associated with impairment of IPA reactivity and structure and increased apoptosis signaling markers. Our findings suggest that androgen deficiency-induced vascular dysfunction is an event involving hypotrophic vascular remodeling of IPAs.

    Full Text Available Background. The end point of this study was to investigate the prevalence of MS in patients with ED in comparison with control subjects and to analyse the association with acute phase reactants (CRP, ESR and hormone levels. Methods. This case-control study included 65 patients, 37 with erectile dysfunction, according to the International Index of Erectile Function (IIEF from the Urology Department of San Cecilio University Hospital, Granada (Spain and 28 healthy controls. The prevalence of metabolic syndrome was calculated according to ATP-III criteria. Hormone levels and acute phase parameters were studied in samples drawn. Results. The ATP-III criteria for MS were met by 64.9% of the patients with ED and only 9.5% of the controls (P<0.0001, OR = 17.53, 95% CI: 3.52–87.37. Binary logistic regression analysis showed a strong association between patients with ED and MS, even after additional adjustment for confounding factors (OR = 20.05, 95% CI: 1.24–32.82, P<0.034. Patients with hypogonadism presented a significantly higher prevalence of metabolic syndrome. Multiple linear regression analysis showed that systolic BP and CRP predicted 0.46 (model R2 of IIEF changes. Conclusion. Chronic inflammation found in patients with ED might explain the association between ED and metabolic syndrome.

    To evaluate the time-course of functional recovery after cavernous nerve injury using glial cell line-derived neurotrophic factor-transduced Schwann cell-seeded silicon tubes. Sections of the cavernous nerves were excised bilaterally (5 mm), followed by immediate bilateral surgical repair. A total of 20 study nerves per group were reconstructed by interposition of empty silicon tubes and silicon tubes seeded with either glial cell line-derived neurotrophic factor-overexpressing or green fluorescent protein-expressing Schwann cells. Control groups were either sham-operated or received bilateral nerve transection without nerve reconstruction. Erectile function was evaluated by relaparotomy, electrical nerve stimulation and intracavernous pressure recording after 2, 4, 6, 8 and 10 weeks. The animals underwent re-exploration only once, and were killed afterwards. The nerve grafts were investigated for the maturation state of regenerating nerve fibers and the fascular composition. Recovery of erectile function took at least 4 weeks in the current model. Glial cell line-derived neurotrophic factor-transduced Schwann cell grafts restored erectile function better than green fluorescent protein-transduced controls and unseeded conduits. Glial cell line-derived neurotrophic factor-transduced grafts promoted an intact erectile response (4/4) at 4, 6, 8 and 10 weeks that was overall significantly superior to negative controls (P cell line-derived neurotrophic factor-transduced grafts compared with negative controls (P = 0.018) and unseeded tubes (P = 0.034). Return of function was associated with the electron microscopic evidence of preganglionic myelinated nerve fibers and postganglionic unmyelinated axons. Schwann cell-mediated delivery of glial cell line-derived neurotrophic factor presents a viable approach for the treatment of erectile dysfunction after cavernous nerve injury. © 2013 The Japanese Urological Association.

    Purpose: Erectile dysfunction is associated with all the common treatment options for prostate cancer. The aim of this research was to evaluate the relationship between erectile function and radiation dose to the penile bulb (PB) and other proximal penile structures in men receiving conformal radiotherapy (CRT) without hormonal therapy (HT) for prostate cancer, whose sexual function was known before treatment. Patients and methods: The study included 19 patients treated with 3D-CRT for localized prostate cancer at our department, who were self-reported to be potent before treatment, had not received HT, and had complete follow-up data available. Our evaluation was based on the International Index of Erectile Function (IIEF-5). Dose-volume histograms (DVHs) were used to evaluate the dose to the PB. Statistical analysis was performed with an unconditional logistic regression model. Results: All patients reported change in potency after radiation. Eight patients (42%) remained potent but showed a decrease of 1 or 2 levels of potency, as defined by the IIEF-5 questionnaire (reduced potency group), while 11 patients (58%) reported a change of higher levels and revealed a severe erectile dysfunction after 2 years (impotence group). Multivariate analysis of morphological and dosimetric variables yielded significance for the mean dose (p = 0.05 with an odds ratio of 1.14 and 95% CI 1-1.30). Patients receiving a mean dose of less than 50 Gy to the PB appear to have a much greater likelihood of maintaining potency. Conclusion: Our data suggest a possible existence of a dose-volume correlation between the dose applied to the PB and radiation-induced impotence. (orig.)

    Alexithymia is a multidimensional construct that describes a constellation of personality features characterised by difficulties in differentiating, identifying and communicating emotions. The purpose of the present study was to investigate prevalence of alexithymia in outpatients with erectile dysfunction (ED), both in the psychogenic lifelong type (PLED) and in the acquired one (PAED). ED severity was evaluated with the International Index of Erectile Function (IIEF) and alexithymia was measured using the Italian version of the 20-item Toronto Alexithymia Scale (TAS-20). The results suggest a high incidence of alexithymic characteristics in patients with psychogenic ED, a positive correlation between the alexithymia level and ED severity in patients with PAED and statistically significant differences in the alexithymia level between the two subgroups PLED and PAED. We assumed that alexithymia contributes to the origin of the PLED, and to a more severe manifestation of ED, once it appears in the acquired form.

    Full Text Available We investigated serum folic acid (FA levels in patients with erectile dysfunction (ED and/or premature ejaculation (PE. Fasting serum samples were obtained from 42 patients with ED, 36 with PE, 25 ED patients with PE, and 30 healthy men; the mean intravaginal ejaculation latency time (IELT was measured during a 4 weeks baseline period. Levels of sex hormones (follicle-stimulating hormone, luteinizing hormone, total testosterone, homocysteine (Hcys, and FA were measured using chemiluminescent immunoassays. The sexual functions of PE patients and normal control men were evaluated using the Chinese Index of Premature Ejaculation (CIPE. The abridged International Index of Erectile Function-5 (IIEF-5 questionnaire was used to gauge erectile quality for ED patients and for normal controls. Serum FA concentrations were lower in ED (7.61 ± 3.97 ng ml -1, PE (9.37 ± 3.40 ng ml -1, and ED/PE (8.84 ± 4.28 ng ml -1 patients than in healthy men (12.23 ± 5.76 ng ml -1 , P 0.05. There were positive correlations between serum FA concentrations and CIPE scores (r = 0.530, P < 0.01, IIEF-5 scores (r = 0.589, P < 0.01, and IELT (r = 0.445, P < 0.01; negative correlations with Hcys concentrations (r = −0.487, P < 0.01 were found in all participants. These findings showed a strong relationship between serum FA levels and sexual dysfunction, possibly due to an effect of FA on the metabolism of nitric oxide, Hcys, and 5-hydroxytryptamine.

This was a prospective study of consecutive patients with CP/CPPS seen at 11 tertiary hospitals during January-July 2014. ED was diagnosed as a score of<21 on the International Index of Erectile Function (IIEF-5. Patients from one center were evaluated by the UPOINT system and NIH-CPSI. Each patient was assessed using clinical examination, asocio-demographic questionnaire, the Patient Health Questionnaire (PHQ, the Pain Catastrophizing Scale (PCS, NIH-CPSI and IIEF-5.1406 patients from 11 centers (mean age, 32.18 years; range 18-60 years were enrolled. ED was found in 638/1406 patients (45.4%, and was categorized as mild in 291(45.6%, moderate in 297(46.6% and severe in50(7.7%. 192 patients from one center(mean age,31.3 years; range 18-57 years were further studied.IIEF-5 score correlated negatively with NIH-CPSI(r = 0.251, PHQ (r = 0.355 and PCS (r = 0.322scores (P<0.001.PHQ score correlated positively with NIH-CPSI (r = 0.586 and PCS(r = 0.662 scores (P<0.001.NIH-CPSI, PHQ, PCS and IIEF-5 scores did not differ significantly between class IIIA and IIIB CP/CPPS. Multivariate logistic regression showed that UPOINT psychological (P domain and NIH-CPSI symptom severity were independent risk factors for ED in CP/CPPS. It is concluded that psychological factors and symptom severity are independent risk factors for ED in CP/CPPS.

    To analyse the proportion of men taking tadalafil 5 mg once daily who experience a combined improvement in symptoms of both erectile dysfunction (ED) and lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). The data from men aged ≥45 years randomized to tadalafil 5 mg once daily or placebo enrolled in one of four randomized, placebo-controlled LUTS/BPH clinical trials were analysed (N = 927). A novel classification of 'combined responders' to ED and LUTS/BPH treatment was defined, based on published criteria for men who showed improvement in both International Index of Erectile Function - Erectile Function domain (IIEF-EF) score and total International Prostate Symptom Score (IPSS). Descriptive analyses assessed the covariate distribution by responder status. Unadjusted and adjusted logistic regressions provided odds ratios with 95% confidence intervals comparing combined responders with all others (partial and non-responders). Among men randomized to tadalafil 5 mg, 40.5% were combined responders (n = 189). Among placebo randomized men, 18.3% were combined responders (n = 84). Combined responders, in the total population, had the highest baseline IPSS and lowest baseline IIEF-EF scores, corresponding to the highest level of dysfunction. The majority of men were aged ≤65 years, white, non-obese, non-smokers, and regular alcohol consumers. Only treatment, baseline IPSS, baseline IIEF-EF, obesity and psychoactive medication use were significantly associated with responder status (P ≤ 0.05). Tadalafil-treated men had 2.8 times significantly increased adjusted odds of being combined responders vs non-responders (P BPH after treatment with tadalafil 5 mg once daily vs placebo. This combined responder measure may be useful in future assessment of treatment benefits across patient groups after various types of treatment intervention (e.g. surgical vs pharmacotherapy vs non-pharmacological intervention). © 2016 The Authors BJU

    INTRODUCTION.: Evidence is accumulating to support the presence of erectile dysfunction in patients with schizophrenia. This dysregulation may be amenable to therapeutic intervention to improve adherence and quality of life of patients who suffer from schizophrenia and schizoaffective disorders. AIM.: We aimed to evaluate the use of adjunctive medication lodenafil for the treatment of erectile dysfunction in outpatients with schizophrenia and spectrum. METHODS.: The design was a randomized, double-blind, crossover, placebo-controlled trial with lodenafil and it was carried at the Schizophrenia Outpatients Program. MAIN OUTCOME MEASURES.: The measures used to assess sexual dysfunction were Arizona Sexual Experiences Scale (ASEX) and International Index of Erectile Function (IIEF). The Positive and Negative Syndrome Scale (PANSS) and the Quality of Life Scale (QLS) were also used. The measures included the levels of prolactin, estradiol, luteinizing hormone, sex hormone-binding globulin, free testosterone, and total testosterone at baseline and end point. Lodenafil and placebo pills were used by the patients for 16 weeks. RESULTS.: Fifty male outpatients fulfilled the criteria and 94% of the participants completed the study. Lodenafil and placebo produced improvement in ASEX, IIEF scale, PANSS, and QLS, and there was no statistical difference between lodenafil and placebo groups in all sexual domains in the results of PANSS and QLS and in the results of hormone levels. CONCLUSION.: These results indicate that both lodenafil and placebo were effective in the treatment of erectile dysfunction for schizophrenia. Placebo effect is very important in patients with schizophrenia and this study showed the importance of discussing sexuality and trying to treat these patients. Further studies designed to test treatments of erectile dysfunction in patients who suffer from schizophrenia are necessary. © 2013 International Society for Sexual Medicine.

    Chronic pain is associated with comorbidities that have an impact on the quality of life of patients and, among others, affect their sexual functioning. One of the most relevant side effects of opioid analgesics is erectile dysfunction (ED), due in part to the inhibition of the gonadal-pituitary-hypothalamic axis and the decline in testosterone levels. To evaluate ED and effectiveness of treatment in men with chronic pain treated with long-term opioids. Prospective observational study lasting 3 years, where the intensity of pain (visual analogue scale, 0-10cm), erectile function (IIEF-EF, range 1-30 points), quality of life (EQ-VAS, 0-100mm), quality of sexual life (MSLQ-QOL, 0-100 points), anxiety/depression (HAD, 0-21 points) and testosterone levels, was assessed in patients who reported sexual dysfunction (ED or libido modification). A 6-month follow-up was applied to each patient after administering the usual treatment in the Andrology Unit. The study was approved by the Clinical Research Ethics Committee and data were statistically analyzed with the GraphPad Prism 5 software. ED was observed in 27.6% of patients (n=105, 57±12.2 years, mean dose of morphine equivalent=107.1±107.9mg/day, 84.3% adjuvant analgesics). After 6 months, 42% of patients showed a significant improvement after being treated with iPDE5 (48.5%) and/or testosterone gel (81.8%), with a resolution rate of 31% (p=0.000). A positive correlation was observed between the improvement of IIEF and quality of sexual life (55.5±25.7 points, p=0.000), as well as anxiety (7.4±4.3 points, p=0.048). No significant changes were observed in the levels of testosterone, in the levels of pain nor in the quality of life, which remained moderate. Erectile function and quality of sexual life, as well as anxiety, improved in patients treated chronically with opioids after administering andrological treatment. The management of patients with pain should include a review of their sexual health history given the

    Objective To assess the prevalence and risk factors of erectile dysfunction (ED) in HIV patients from the HIV clinic of a tertiary referral center in Mexico City. Design Prevalence was obtained from cross-sectional studies, and the International Index of Erectile Function (IIEF), a standardized method, was used to assess ED. Methods A cross-sectional study was performed in the HIV clinic. Participants completed the IIEF to allow ED assessment. Information on demographics, clinical and HIV-related variables was retrieved from their medical records. Results One hundred and nine patients were included, with a mean age of 39.9 ± 8.8 years. ED was present in 65.1% of the individuals. Patients had been diagnosed with HIV for a mean of 92.7 ± 70.3 months and had undergone a mean 56.4 ± 45.5 months of HAART. The only variable associated with ED in the univariate analysis was dyslipidemia, and this association was also found in the multivariate analysis (P = 0.01). Conclusions ED is highly prevalent in HIV patients. Dyslipidemia should be considered as a risk factor for ED in HIV patients.

    Full Text Available The purpose of this study was to determine the influence of metabolic syndrome (MS and serum testosterone in patients with erectile dysfunction (ED and their possible association. A total of 103 men with ED were enrolled. The International Index of Erectile Function (IIEF questionnaire was used to assess erectile condition. MS was defined according to the criteria formulated by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III and the International Diabetes Federation (IDF. The mean age of the study population was 57.5 ± 10.7 years, with an average IIEF of 14.7 ± 6.7. The age and prevalence of MS using the NCEP ATP III criteria, but not the IDF criteria, were significantly different between mild and moderate/severe ED patients (p = 0.031 and 0.009, respectively. The percentage of hypertension (78.6% vs. 36.2%; p < 0.001 and raised fasting glucose levels (46.4% vs. 19.1%; p = 0.004 were significantly higher in the moderate/severe ED group, and both differences remained significant in multivariate analysis (p = 0.001 and 0.042, respectively. In addition, serum testosterone levels were significantly lower in ED patients with MS (p = 0.002. In summary, the presence of MS is associated with more severe ED. Among the components of MS, elevated blood pressure and fasting blood glucose were independent risk factors. NCEP ATP III criteria seem to correlate better with the degree of ED than the IDF definition. Our results also indicate that MS is associated with a lower testosterone level in patients with ED.

    To compare sexual function and hormone profile in male patients with gynecomastia with matched controls. Forty-seven male subjects with gynecomastia and thirty healthy controls were enrolled in this study. Serum free T3, free T4, TSH, FSH, prolactin, estradiol, total testosterone, free testosterone, DHEA-SO4, LH and total PSA were measured in the patients and controls. Sexual function of the patients and controls were evaluated using International Index of Erectile Function (IIEF). The hormone values and IIEF scores of the patients were statistically compared with the controls'. The mean of age, body mass index, right and left testicular volume in the patient and control group were similar. The mean FSH and free T3 values of the patients were significantly lower than the controls (p = 0.007 and p = 0.03, respectively). The mean of the other hormone values in the both groups were found to be statistically similar (p > 0.05). The mean ±SD of total IIEF scores in the patient and control group were 60.14 ± 8.78 and 65.24 ± 5.52, respectively (p = 0.007). Although the mean IIEF-erectile function, orgasmic function and intercourse satisfaction scores in the patient group were significantly lower than the control group (p gynecomastia were similar with the controls. However, gynecomastia adversely affected male sexual function.

    There is a growing recognition of the association between chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and erectile dysfunction (ED); however, most of the reports are based on questionnaires which cannot distinguish between organic and functional ED. The purpose of this study was to determine the exact relationship between CP/CPPS and ED, and to investigate the changes in erectile organ structure and function in a rat model of CP/CPPS. We established a rat model of experimental autoimmune prostatitis (EAP), which is a valid model for CP/CPPS. Erectile function in EAP and normal rats was comparable after cavernous nerve electrostimulation. The serum testosterone and oestradiol levels, ultrastructure of the corpus cavernosum and expression of endothelial nitric oxide synthase and neuronal nitric oxide synthase in the two groups were similar; however, there was a decrease in smooth muscle-to-collagen ratio and alpha-smooth muscle actin expression and an increase in transforming growth factor-beta 1 expression was observed in EAP rats. Thus, organic ED may not exist in EAP rats. We speculate that ED complained by patients with CP/CPPS may be psychological, which could be caused by impairment in the quality of life; however, further studies are needed to fully understand the potential mechanisms underlying the penile fibrosis in EAP rats. © 2015 Blackwell Verlag GmbH.

    The aim of this study was to investigate the relation between lower urinary tract symptoms (LUTS), erectile dysfunction (ED) and depression in Japanese patients with late-onset hypogonadism (LOH) symptoms. The study comprised 87 Japanese patients with LOH symptoms (>27 points on the Aging Males Symptoms Scale). Thirty-four patients were diagnosed as having depression and the remaining 53 patients were diagnosed as not having depression by the Mini International Neuropsychiatric Interview. We compared the International Index of Erectile Function (IIEF) 5, International Prostate Symptom Score (IPSS), IPSS quality-of-life (QOL) index, King's Health Questionnaire (KHQ), endocrinological data, and free uroflow study between depression and non-depression patients and performed multiple logistic regression analysis. IIEF5 scores of depression patients were significantly lower than those of non-depression patients. In KHQ, only the category of general health perceptions was significantly higher in depression patients than non-depression patients. However, IPSS, QOL index, and endocrinological and uroflowmetric data showed no significant difference between the groups. Multiple logistic regression analysis revealed moderate and severe ED to be risk factors for depression. However, LUTS are not related to depression. Moderate and severe ED is correlated with depression, whereas LUTS are not related to depression in Japanese LOH patients.

    The aim of the present study was to evaluate the prevalence of lifetime posttraumatic stress disorder (PTSD) in Turkish male alcohol-dependent inpatients, and to investigate the relationship of lifetime PTSD diagnosis with anxiety, depression, hopelessness, erectile dysfunction and psychosocial problems related with alcohol dependency. Eighty-two male inpatients who met DSM-IV criteria for alcohol dependence and 48 subjects without substance use disorder as a control group were included in the study. Subjects were applied the Hamilton Depression Rating Scale (HAM-D), the Hamilton Anxiety Rating Scale (HAM-A), the Michigan Alcoholism Screening Test (MAST), the Beck Hopelessness Scale (BHS) and the International Index of Erectile Function (IIEF). Rate of lifetime PTSD diagnosis was found to be 26.8% among alcohol-dependent inpatients. The mean age of patients with lifetime PTSD was lower than in patients without this diagnosis, while there were no significant differences between these two groups in terms of age of first alcohol use, lifetime major depression, current depression, presence and severity of erectile dysfunction. Mean scores of HAM-D, HAM-A, BHS and MAST in the group with lifetime PTSD were significantly higher than the group without this diagnosis. There was a positive relationship between lifetime PTSD diagnosis and depression, anxiety, hopelessness and severity of psychosocial problems related to alcohol dependency, while there was no relationship between lifetime PTSD comorbidity and erectile dysfunction in alcohol-dependent patients.

    The quality of life consequences of erectile dysfunction (ED) include depression, anxiety, and loss of self-esteem. The Self-Esteem And Relationship (SEAR) questionnaire is a validated, patient-administered, psychometric instrument specific to ED. To determine correlations between erectile function (EF), intercourse success, and emotional well-being measured with the SEAR questionnaire in men treated with sildenafil citrate for ED and stratified by age ( 65 years). This was an open-label, flexible-dose trial of sildenafil (25, 50 and 100 mg) administered for 10 weeks to 382 men with ED (mean +/- SD age, 55 +/- 13 years; mean ED duration, 4 years), which was conducted at 62 centers in the United States. Analysis (by intent-to-treat, n = 368) of the change from baseline to the week-10 endpoint in the SEAR questionnaire Self-Esteem subscale, the intercourse success rate (percent of occasions at which an erection that lasted long enough for successful intercourse was achieved), and their correlation. For the overall population, there was mean +/- SD improvement (p Erectile Function; event log frequency of erection hard enough for sexual intercourse and of ejaculation/orgasm) also improved (p 65 years, and six were positive in men aged erectile function and an increased intercourse success rate, which correlated positively with improvement in SEAR measures of self-esteem and sexual relationship.

  4. Radiation therapy for prostate cancer and erectile (dys)function: The role of imaging

    Incidence of erectile dysfunction (ED) after radiotherapy reported in the literature varies from 7 to 72% after external-beam radiotherapy to 5-51% after brachytherapy. Most of these studies are retrospective, the definition of ED is variable and sexual functioning is frequently assessed by asking only one question. Already in the 1980's it was suggested that post-radiation ED was attributable to vascular damage. The most reliable method to assess vasculogenic ED is the use of the Doppler ultrasound. More recently, many studies have assessed the relationship between radiation dose and volume of the penile bulb and post-radiation ED, though the outcome is controversial. The penile structures and the neurovascular bundles are best seen on magnetic resonance imaging (MRI). Therefore the use of a computer tomography scan/MRI image fusion can result in reducing the planning target volume and consequently the radiation dose to the penile bulb and bodies. If radiation induces vascular damage that causes ED, any means of reducing the dose to the pelvic vascular structures would likely decrease ED, therefore new radiation techniques such as the intensity modulated radiation therapy or the implant of fiducial markers can help decrease the margins and therefore ED.

    Erectile dysfunction is highly prevalent in type II diabetes mellitus. Low intensity extracorporeal shock wave therapy improves erectile function in patients with erectile dysfunction of vasculogenic origin, including diabetes. However, its mode of action remains unknown. We investigated the effects of low intensity extracorporeal shock wave therapy compared to or combined with sildenafil on erectile dysfunction in a type II diabetes mellitus model. Our purpose was to test our hypothesis of a mode of action targeting the cavernous nitric oxide/cyclic guanosine monophosphate pathway. GK rats, a validated model of type II diabetes mellitus, and age matched Wistar rats were treated with low intensity extracorporeal shock wave therapy twice weekly for 3 weeks. Treatment was repeated after a 3-week no-treatment interval. The penis was stretched and dipped in a specifically designed water-filled cage. Shock waves were delivered by a calibrated probe yielding a controlled energy flux density (0.09 mJ/mm(2)). The probe was attached to an electrohydraulic unit with a focused shock wave source, allowing for accurate extrapolation to humans. Following a 4-week washout period erectile function was assessed as well as endothelium dependent and independent, and nitrergic relaxations of the corpus cavernosum of GK rats. Low intensity extracorporeal shock wave therapy significantly improved erectile function in GK rats to the same extent as sildenafil. Treatment effects were potentiated when combined with sildenafil. Shock wave effects were not associated with improved cavernous endothelium dependent or independent, or nitrergic reactivity. Low intensity extracorporeal shock wave therapy improved erectile function in GK rats. Unexpectedly, this was not mediated by a nitric oxide/cyclic guanosine monophosphate dependent mechanism. Sildenafil increased shock wave efficacy. This preclinical paradigm to deliver low intensity extracorporeal shock wave therapy to the rat penis should

    Tiger nut tubers have been reportedly used for the treatment of erectile dysfunction (ED) in folk medicine without scientific basis. Hence, this study evaluated the effect of tiger nut on erectile dysfunction by assessing biochemical parameters relevant to ED in male rats by nitric oxide synthase (NOS) inhibitor, Nω-nitro-l-arginine methyl ester hydrochloride (l-NAME) treatment. Rats were divided into five groups (n = 10) each: Control group; l-NAME plus basal diet; l-NAME plus Sildenafil citrate; diet supplemented processed tiger nut (20%) plus l-NAME;diet supplemented raw tiger nut (20%) plus l-NAME. l-NAME pre-treatment (40 mg/kg/day) lasted for 14 days. Arginase, acetycholinesterase (AChE) and adenosine deaminase (ADA) activities as well as nitric oxide levels (NO) in serum, brain and penile tissue were measured. l-NAME increased the activity of arginase, AChE and ADA and reduced NO levels. However, dietary supplementation with tiger nut caused a reduction on the activities of the above enzymes and up regulated nitric oxide levels when compared to the control group. The effect of tiger nut supplemented diet may be said to prevent alterations of the activities of the enzymes relevant in erectile function. Quercetin was revealed to be the most active component of tiger nut tuber by HPLC finger printing. Copyright © 2018. Published by Elsevier Ltd.

    The objective of this work is to evaluate the impact of 120-W 2-μm continuous wave (cw) laser vapoenucleation of the prostate in patients with benign prostatic hyperplasia (BPH) on sexual function. One hundred twenty-two consecutive patients with BPH were retrospectively collected in this study and were classified into two groups for surgical treatment with 2-μm cw laser vapoenucleation or transurethral resection of the prostate (TURP). International Index of Erectile Function (IIEF) and general assessment questions were completed before and 12 months after treatment to determine the impact on sexual function. A total of 33 patients (52.4%) in group 1 and 31 (52.5%) in group 2 reported various degrees of erectile dysfunction before surgery. Interestingly, an increase in IIEF-EF score by 2 points was reported by 16 (25.4%) and 14 (23.7%) patients, respectively, and mean EF score did show a marginal but not significant increase postoperatively in both group. Differences about orgasmic intercourse satisfaction, sexual desire domain, and overall satisfaction scores in each group were not significant between preoperative and postoperative, but there was a significant decrease in the orgasmic function domain score at 12 months postoperation in both groups (p function. No significant erectile function improvement was observed after surgery, but these two techniques significantly lowered the IIEF orgasmic function domain and this was mainly caused by retrograde ejaculation.

    Full Text Available BackgroundSexuality is an essential part of life; however, erectile dysfunction (ED has been one of the most common complaints among men with sexual health issues all over the world. ED includes dysfunction in erection and penile erectile pain. In Vietnam, ED is a subject a not readily discussed. Thus, relatively little is known about ED among Vietnamese men.AimsTo identify the prevalence of ED and its associated variables and the need for treatment of ED among married men in Vietnam.MethodsThis was a cross-sectional study. A total sample size included 746 married men, aged 20–60 years, living in four representative wards of the Hue City and randomly selected by systematic sampling methods. Respondents completed a self-reported questionnaire. The International Index of Erectile Function (IIEF-5 scale was used to determine ED severity, and the Depression Anxiety Stress Scales (DASS-21 was used to measure depression, anxiety, and stress. Quality of life was assessed using the WHO Quality of Life score (WHOQoL. A multivariate logistic regression model was used to determine the relationships between independent variables and ED.ResultsMean age of married men was 44.3 ± 8.7. Two-thirds (66.9% of respondents experienced ED symptoms. In terms of severity, 40.8% reported mild ED; 20.3% mild–moderate ED; 5.0% moderate ED; and 0.8% severe ED. Depression, anxiety, and stress problems were 5.0, 3.6, and 2.8%, respectively. One-third (33.1% of the respondents reported having low quality of life, and 32.6% reported having medium quality of life. The vast majority (86.9% had consensual sex with their wives/partners. Variables associated with increased IIEF-5 score were increased WHOQoL score, increased body mass index (BMI, religion, and no consumption of alcohol. Increasing age, disease history, increased anxiety, and no consensual sex with their wife/partner were associated with a lower IIEF-5 score. If experiencing ED, 55.5% would seek help from

    Purpose To evaluate how much the improvement of lower urinary tract symptoms (LUTS) affects sexual function and which storage symptoms or voiding symptoms have the greatest effect on sexual function. Materials and Methods A total of 187 patients were enrolled in this study. Patients were randomly assigned to receive either tamsulosin 0.2 mg (group A) or tamsulosin 0.2 mg and solifenacin 5 mg (group B). At 4 weeks and 12 weeks, the LUTS and sexual function of the patients were evaluated by use of the International Index of Erectile Function-5 (IIEF5), International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS) questionnaire, uroflowmetry, and bladder scan. Results Both groups A and B showed statistically significant improvements in IPSS, OABSS, and quality of life (QoL). Group A showed improved maximum flow rate, mean flow rate, and residual urine volume by time. Group B did not show an improvement in flow rate or residual urine volume but total voiding volume increased with time. The IIEF5 score was not improved in either group. In group A, the IIEF5 score dropped from 13.66±4.97 to 11.93±6.14 after 12 weeks (p=0.072). Group B showed a decline in the IIEF5 score from 13.19±5.91 to 12.45±6.38 (p=0.299). Although group B showed a relatively smaller decrease in the IIEF5 score, the difference between the two groups was not significant (p=0.696). Conclusions Tamsulosin monotherapy and combination therapy with solifenacin did not improve erectile function despite improvements in voiding symptoms and QoL. The improvement in storage symptoms did not affect erectile function. PMID:25237463

    This is a phase III, prospective, randomized, double-blind, placebo-controlled clinical trial on lodenafil carbonate (LC), a novel phosphodiesterase 5 inhibitor developed in Brazil. Expanding information on LC efficacy and safety. International Index of Erectile Function (IIEF) erectile domain, positive answers to the sexual encounter profile (SEP)-2 and SEP-3 questions and incidence of adverse events (AEs). A total of 350 men with erectile dysfunction (ED) of all degrees were randomized to placebo, LC 40 mg or LC 80 mg and followed for 4 weeks. They completed the IIEF and answered the SEP questions 2 and 3 after each intercourse without and with the use of LC. IIEF Erectile Domain scores without and with the use of medication were the following (mean [M] +/- standard deviation [SD]): placebo = 13.9 +/- 5.2 and 14.8 +/- 7.8; LC 40 mg = 13.6 +/- 5.3 and 18.6 +/- 8.0; LC 80 mg = 13.4 +/- 4.9 and 20.6 +/- 7.7 (analysis of variance [ANOVA] P < 0.01). Positive answers to SEP-2 without and with the use of medication were the following (M +/- SD): placebo = 55.3 +/- 43.2% and 52.1 +/- 41.4%; LC 40 mg = 46.4 +/- 44.3% and 63.5 +/- 42.0%; LC 80 mg = 50.2 +/- 40.9% and 80.8 +/- 32.3% (ANOVA P < 0.01). Positive answers to SEP-3 were the following: placebo = 20.2 +/- 32.3% and 29.7 +/- 38.1%; LC 40 mg = 19.6 +/- 34.3% and 50.8 +/- 44.4%; LC 80 mg = 20.8 +/- 33.2% and 66.0 +/- 39.3% (ANOVA P < 0.01). The patients with at least one AE were placebo = 28.7%, LC 40 mg = 40.9%, and LC 80 mg = 49.5%. AEs whose incidence was significantly higher with LC than with placebo included rhinitis, headache, flushing, visual disorder, and dizziness. LC showed a satisfactory efficacy-safety profile for oral therapy of ED.

    Erectile dysfunction (ED) is common among men taking antihypertensive agents to control blood pressure. We evaluated the efficacy and safety of sildenafil citrate in men with ED taking antihypertensive agents. A total of 198 male subjects, aged 20 years and older were enrolled. This study was conducted for 10 weeks as an open-label, multicenter and flexible dose trial with a 2-week screening period and an 8-week treatment phase. Subjects were asked to complete Event Log Worksheets, as well as the International Index of Erectile Function (IIEF) and the Global Efficacy Assessment Questions (GEAQ) questionnaires during the study period. The average age among the 167 subjects who completed the study was 55.8 (31.7 to 77.1). The scores for questions 3 and 4 of IIEF improved from 2.3 and 1.8 at baseline to 3.7 and 3.4 at week 4 and 3.8 and 3.4 at week 8, respectively. There were 86.3% of the patients reported improved erectile function at week 8; 88.3% of the patients reported improved ability to achieve sexual intercourse at week 8. There were no significant differences observed in the responses to questions 3 and 4 of IIEF and GEAQ by the number of antihypertensive agents taken. The adverse events were facial flushing (20.1%), headache (11.7%), palpitation (5.0%), rhinitis (2.8%), URI (2.8%), dizziness (2.2%), dyspnea (2.2%), and nausea (1.7%). Sildenafil citrate is an effective treatment for ED; it is safe and well tolerated by patients with ED taking multiple antihypertensive agents for arterial hypertension.

    The effects of vitamin D on sexual function are very unclear. Therefore, we aimed at evaluating the possible association between vitamin D and sexual function and at assessing the influence of vitamin D administration on sexual function. We retrospectively studied 114 men by evaluating clinical, biochemical, and sexual parameters. A subsample ( n = 41) was also studied longitudinally before and after vitamin D replacement therapy. In the whole sample, after performing logistic regression models, higher levels of 25(OH) vitamin D were significantly associated with high values of total testosterone and of all the International Index of Erectile Function (IIEF) questionnaire parameters. On the other hand, higher levels of total testosterone were positively and significantly associated with high levels of erectile function and IIEF total score. After vitamin D replacement therapy, total and free testosterone increased and erectile function improved, whereas other sexual parameters did not change significantly. At logistic regression analysis, higher levels of vitamin D increase (Δ-) were significantly associated with high values of Δ-erectile function after adjustment for Δ-testosterone. Vitamin D is important for the wellness of male sexual function, and vitamin D administration improves sexual function.

    Full Text Available Introduction. There is an increasing interest in the association between erectile dysfunction (ED and cardiovascular risk factor. Epicardial adipose tissue (EAT is associated with insulin resistance, increased cardiometabolic risk, and coronary artery disease. Our aim was to investigate relationships between epicardial fat thickness (EFT as a cardiometabolic risk factor and erectile dysfunction. Method. We selected 30 erectile dysfunction patients without comorbidities and 30 healthy individuals. IIEF-5 score was applied to all patients, and IIEF-5 score below 22 was considered as erectile dysfunction. EFT was measured by echocardiography. Results. Body mass index (BMI was higher in ED patients than those without ED (28.19 ± 4.45 kg/m2 versus 23.84±2.36 kg/m2, P = 0.001, resp.. Waist circumstance (WC was higher in ED patients than those without ED (106.60±5.90 versus 87.86 ± 14.51, P = 0.001, resp.. EFT was higher in ED patients compared to non-ED patients (0.49 ± 0.09 cm versus 0.45 ± 0.03 cm, P = 0.016, resp.. There was positive correlation among BMI, WC, and EFT. There was negative correlation between EFT and IIEF-5 score (r : -0.632, P = 0.001. Conclusion. EAT, BMI, and WC as cardiometabolic risk factors were higher in erectile dysfunction patients.

    For patients with diabetes, erectile dysfunction (ED) is common and greatly affects quality of life. However, these patients often exhibit a poor response to first-line oral phosphodiesterase type 5 inhibitors. To investigate whether taurine, a sulfur-containing amino acid, affects diabetic ED (DED). Type 1 diabetes mellitus was induced in male rats by using streptozotocin. After 12 weeks, an apomorphine test was conducted to confirm DED. Only rats with DED were administered taurine or vehicle for 4 weeks. Age-matched nondiabetic rats were administered saline intraperitoneally for 4 weeks. Erectile function was evaluated by electrical stimulation of the cavernous nerve. Histologic and molecular alterations of the corpus cavernosum also were analyzed. Erectile function was significantly reduced in the diabetic rats compared with in the nondiabetic rats, and was improved in the diabetic rats treated with taurine. The corpus cavernosum of the rats with DED exhibited severe fibrosis and decreased smooth muscle content. Deposition of extracellular matrix proteins was increased in the diabetic rats, while expression of endothelial nitric oxide synthase/cyclic guanosine monophosphate/nitric oxide pathway-related proteins was reduced. Taurine supplementation ameliorated erectile response as well as histologic and molecular alterations. Taurine supplementation improves erectile function in rats with DED probably by potential antifibrotic activity. This finding provides evidence for a potential new therapy for DED.

    Stem cell transplantation and low-energy shock-wave therapy (LESWT) have emerged as potential and effective treatment protocols for diabetic erectile dysfunction. During the tracking of transplanted stem cells in diabetic erectile dysfunction models, the number of visible stem cells was rather low and decreased quickly. LESWT could recruit endogenous stem cells to the cavernous body and improve the microenvironment in diabetic cavernous tissue. Thus, we deduced that LESWT might benefit transplanted stem cell survival and improve the effects of stem cell transplantation. In this research, 42 streptozotocin-induced diabetic rats were randomized into four groups: the diabetic group (n = 6), the LESWT group (n = 6), the bone marrow-derived mesenchymal stem cell (BMSC) transplantation group (n = 15), and the combination of LESWT and BMSC transplantation group (n = 15). One and three days after BMSC transplantation, three rats were randomly chosen to observe the survival numbers of BMSCs in the cavernous body. Four weeks after BMSC transplantation, the following parameters were assessed: the surviving number of transplanted BMSCs in the cavernous tissue, erectile function, real-time polymerase chain reaction, and penile immunohistochemical assessment. Our research found that LESWT favored the survival of transplanted BMSCs in the cavernous body, which might be related to increased stromal cell-derived factor-1 expression and the enhancement of angiogenesis in the diabetic cavernous tissue. The combination of LESWT and BMSC transplantation could improve the erectile function of diabetic erectile function rats more effectively than LESWT or BMSC transplantation performed alone.

    Lepidium meyenii (Maca) is a cultivated root belonging to the brassica family used in the Andean region for its supposed aphrodisiac properties. We carried out a double-blind clinical trial on 50 Caucasian men affected by mild erectile dysfunction (ED), randomised to treatment with Maca dry extract, 2400 mg, or placebo. The treatment effect on ED and subjective well-being was tested administrating before and after 12 weeks the International Index of Erectile Function (IIEF-5) and the Satisfaction Profile (SAT-P). After 12 weeks of treatment, both Maca- and placebo-treated patients experienced a significant increase in IIEF-5 score (P Maca experienced a more significant increase than those taking placebo (1.6 +/- 1.1 versus 0.5 +/- 0.6, P Maca- and placebo-treated subjects experienced a significant improvement in psychological performance-related SAT-P score, but the Maca group higher than that of placebo group (+9 +/- 6 versus +6 +/- 5, P Maca-treated patients experienced a significant improvement in physical and social performance-related SAT-P score compared with the baseline (+7 +/- 6 and +7 +/- 6, both P Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED.

    Current treatments for erectile dysfunction (ED) have some limitations. This study evaluated the efficacy and tolerability of MED2005, a 0.2% glyceryl trinitrate topical gel, formulated into an enhanced absorption topical delivery system (DermaSys), administered on demand, in the treatment of ED. This randomized, double-blinded, placebo-controlled, phase II crossover trial involved 232 men with ED (231 treated, 230 assessed for efficacy) and their partners. After a 4-week run-in period, patients were randomized to 1 of 2 treatment sequences, MED2005-placebo or placebo-MED2005. Each treatment was given for 4 weeks, separated by a 1-week washout interval. Efficacy was assessed by the International Index of Erectile Function (IIEF), the Sexual Encounter Profile, a Global Assessment Questionnaire (GAQ), and specific questions about the onset and offset of action and treatment preferences (patients and partners). The primary outcome measure was the IIEF erectile function domain (IIEF-EF) score. Other efficacy assessments were secondary outcomes. The mean baseline IIEF-EF score was 17.1 (SD = 5.7), and this increased to 19.6 (SD = 7.5) after MED2005 treatment and 18.5 (SD = 6.7) after placebo (P = .0132). Overall, 23.1% of patients showed a clinically relevant (≥4-point) increase in IIEF-EF scores after treatment with MED2005 only compared with 14.5% who responded after MED2005 and placebo, 14.0% who responded after placebo only, and 48.4% who did not respond after either treatment (P = .0272). MED2005 also was associated with significant improvements compared with placebo in the other IIEF domains, and this was consistent with patients' and partners' responses to the GAQ. For all assessments, significant effects of MED2005 were seen primarily in patients with mild ED. The start of erection was noticed within 5 and 10 minutes in 44.2% and 69.5%, respectively, of all intercourse attempts with MED2005. Patients and partners showed significant preferences for MED2005

    Phosphodiesterase type-5 inhibitors (PDE5Is) are first-line therapies for erectile dysfunction (ED). Sildenafil (SIL) and vardenafil (VAR) are approved for as-needed (PRN) dosing; tadalafil (TAD) is approved for both PRN and once-a-day (OaD) dosing for ED. Recent evidence suggests that TAD-OaD may be effective as therapy in men with an incomplete response to PRN-PDE5I therapy. This study evaluated whether TAD-OaD provides similar efficacy in men with ED who had previously demonstrated a partial response to PRN-PDE5I therapy. In this randomized, double-blind, placebo-controlled trial, men with a ≥3 month ED history received SIL 100 mg, TAD 20 mg, or VAR 20 mg during a 4 week open-label lead-in period. Those with International Index of Erectile Function - Erectile Function (IIEF-EF) domain scores TAD 2.5 mg up-titrated to 5 mg, TAD 5 mg, or placebo (PBO) OaD for 12 weeks. MAIN OUTCOME MEASURES obtained from patients treated with TAD-OaD were compared to PBO-treated patients. Additionally, results of treatment with TAD-OaD were compared to results obtained from 4 week PRN-PDE5I therapy to determine whether OaD and PRN regimens provided comparable efficacy. NCT01130532. International Index of Erectile Function (IIEF) domain scores; Sexual Encounter Profile (SEP) questions 2-5. Endpoint data was obtained from 590 men (391 TAD; 199 PBO). RESULTS for all IIEF and SEP measures were significantly better for TAD-OaD (p TAD 2.5 mg and TAD 5 mg OaD therapy were safe and generally well tolerated. Tadalafil once daily is a viable alternative to as-needed PDE5I therapy in men with ED. Key limitations include the lack of a PRN PDE5I study group during the double-blind period, and that many more patients took tadalafil than sildenafil or vardenafil during the PRN period.

    Erectile dysfunction (ED) is a major health problem. We have shown that adrenomedullin (AM) restores erectile function in diabetic rats. The aim of this study is to explore a better treatment for ED, we examined whether combination of AM and angiopoietin-1 (Ang-1) was more effective to treat ED than treatment with AM alone or Ang-1 alone. We also compared the effect of the combination therapy with that of treatment with vascular endothelial growth factor-A (VEGF-A). Male Wistar rats were injected with streptozotocin (STZ) to induce diabetes. Adenoviruses expressing AM (AdAM), Ang-1 (AdAng-1), and VEGF-A (AdVEGF-A) were injected into the penis 6 weeks after STZ administration. Erectile function, penile histology, and protein expression were analyzed 4 weeks after the injection of the adenoviruses. Intracavernous pressure and mean arterial pressure were measured to evaluate erectile function. The morphology of the penis was analyzed by Elastica van Gieson stain and immunohistochemistry. The expression of α-smooth muscle actin (SMA), VE-cadherin and type I collagen was assessed by Western blot analysis. Infection with AdAM plus AdAng-1 more effectively restored erectile function than infection with AdAM alone or AdAng-1 alone. This combination therapy restored erectile function to a level similar to that observed in the age-matched Wistar rats. Expression of SMA and VE-cadherin increased more significantly in the AdAM plus AdAng-1-treated group than in the AdAM- or AdAng-1-treated group. Although AdVEGF-A infection restored erectile function significantly, it also caused enlargement of the trabeculae of the cavernous body, aberrant angiogenesis, and overproduction of type I collagen. These results suggested that combination therapy with AM and Ang-1 potently restored erectile function and normal morphology of the cavernous body compared with VEGF-A administration. This combination therapy will be useful to treat ED patients with a severely damaged cavernous body.

    We evaluated the effectiveness of tamsulosin monotherapy versus tamsulosin plus sildenafil combination therapy on erectile dysfunction (ED) in young patients with type III chronic prostatitis and ED by using symptom score scales. 44 male patients were divided into 2 groups: the first group (20 patients) was treated with tamsulosin 0,4 mg monotherapy and the second one 24 patients) was treated with tamsulosin 0,4 mg plus sildenafil 50 mg combination therapy. “International Prostate Symptom Score, “National Institute of Health Chronic Prostatitis Symptom Index" (NIH-CPSI) and “International Index of Erectile Function" (IIEF-5) were investigated in each group of patients, and scores calculated during the first medical examination. Both groups were treated with tamsulosin once daily for 60 days, while sildenafil 50 mg was given on demand (at least 2 times per week) for 60 days. During the second medical examination IPSS, NIH-CPSI and IIEF-5 scores were analyzed once more. Afterwards, the alterations of scores among medical examinations in each group and between both groups were statistically compared. The age average of the 44 cases included was 32.04 3.15 years. Both groups present a statistically significant decrease, between the first and the second medical examination, in IPSS, NIH-CPSI scores and statistically significant increase in IIEF-5 score. In addition, there is no statistically significant difference, in all scores, between mono and combination therapy. tamsulosin monotherapy, as well as a combination therapy (tamsulosin plus sildenafil) has an improving effect on symptoms and on ED in patients with type III prostatitis. In the near future alpha-blockers monotherapy could be used in the treatment of chronic prostatitis and ED cases instead of phosphodiesterase type 5 (PDE-5) inhibitors combination therapy.

    This study aimed to elucidate the relationships between erectile dysfunction (ED) and depression or anxiety. Subjects were 1,419 Japanese men aged 40-64 years. ED was assessed by the International Index of Erectile Function 5 (IIEF-5) score (Japanese version), and depression and anxiety symptoms were assessed by the Hospital Anxiety and Depression Scale (HADS). In this study ED cases were defined as those whose IIEF-5 value was less than 12, and a score of 8 or higher was used to classify a subject as suffering from depression or anxiety, respectively. The prevalence odds ratio (OR) of ED was calculated with confidence interval (CI) estimated by the Woolf's method by five age groups (40-44, 45-49, 50-54, 55-59, 60-64 years). To control for age, body mass index, smoking, and alcohol drinking factors, we conducted the multivariate logistic regression analysis for calculating adjusted ORs and 99% CIs. ED was significantly associated with depression in age groups 45-49 (OR 3.42, 99% CI 1.51-7.76) and 50-54 years (OR 2.43, 99% CI 1.11-5.35). After using multivariate analysis, adjusted OR also showed statistical significance. (OR 2.02, 99% CI 1.32-3.08). ED was significantly associated with anxiety in the 50-55-year-old age group (OR 2.48, 99% CI 1.12-5.47). After using multivariate analysis, adjusted OR also showed statistical significance (OR 1.77, 99% CI 1.15-2.72). The concomitant depression and anxiety group (A+D+) had significantly higher prevalence of ED than the control group (A-D-) in both the 45-49 and 50-54 age groups. (P < 0.01) ED associated significantly with depression and anxiety status only in late 40s to early 50s (45-55 years) in male Japanese. Furthermore, comorbidities of depression and anxiety strengthen this association. Our results might be useful in furthering understanding of ED etiology and determining a target population for prevention in ED subjects.

    To study a novel penile reinnervation technique using four sural nerve grafts and end-to-side neurorraphies connecting bilaterally the femoral nerve and the cavernous corpus and the femoral nerve and the dorsal penile nerves. Ten patients (mean [± sd; range] age 60.3 [± 4.8; 54-68] years), who had undergone radical prostatectomy (RP) at least 2 years previously, underwent penile reinnervation in the present study. Four patients had undergone radiotherapy after RP. All patients reported satisfactory sexual activity prior to RP. The surgery involved bridging of the femoral nerve to the dorsal nerve of the penis and the inner part of the corpus cavernosum with sural nerve grafts and end-to-side neurorraphies. Patients were evaluated using the International Index of Erectile Function (IIEF) questionnaire and pharmaco-penile Doppler ultrasonography (PPDU) preoperatively and at 6, 12 and 18 months postoperatively, and using a Clinical Evolution of Erectile Function (CEEF) questionnaire, administered after 36 months. The IIEF scores showed improvements with regard to erectile dysfunction (ED), satisfaction with intercourse and general satisfaction. Evaluation of PPDU velocities did not reveal any difference between the right and left sides or among the different time points. The introduction of nerve grafts neither caused fibrosis of the corpus cavernosum, nor reduced penile vascular flow. CEEF results showed that sexual intercourse began after a mean of 13.7 months with frequency of sexual intercourse varying from once daily to once monthly. Acute complications were minimal. The study was limited by the small number of cases. A total of 60% of patients were able to achieve full penetration, on average, 13 months after reinnervation surgery. Patients previously submitted to radiotherapy had slower return of erectile function. We conclude that penile reinnervation surgery is a viable technique, with effective results, and could offer a new treatment method for ED after

    Chronic periodontitis (CP) is characterized with inflammation of the gingival tissues, which causes endothelial dysfunction in different organs. In this study, we investigated the association of CP with the erectile dysfunction (ED). The study group included 80 male patients with ED and 82 male patients without ED (control), aged between 30 and 40 years. The International Index of Erectile Function (IIEF) questionnaire was used to assess male sexual function, particularly the presence or absence of ED. The patients in the study and control groups were statistically compared according to their plaque index (PI), bleeding on probing (BoP), probing depth (PD), and clinical attachment level (CAL). In the non-ED and the ED groups, the mean age was 35.7 ± 4.8 and 34.9 ± 4.9 years, respectively. Patients' characteristics including body mass index, household income, and education status were similar in both groups (P > 0.05). Nineteen patients (23%) had severe CP in the non-ED group; 42 patients (53%) had severe CP in the ED group. Logistic regression analysis showed a significantly high association between ED and the severity of CP (odds ratio: 3.29, 95% confidence interval: 1.36-9.55, P 4 mm and sites with CAL >4 mm were significantly higher in the ED group than in the control group (P 0.05).

    Oral treatment with phosphodiesterase type 5 inhibitor (PDE5) is considered the first-line treatment for patients with erectile dysfunction (ED). Lodenafil carbonate (LC) is a novel PDE5. This is a phase II, prospective, randomized, double-blind, and placebo controlled clinical trial of LC. Efficacy end points were International Index of Sexual Function (IIEF) erectile domain, IIEF questions 3 and 4, and Sexual Encounter Profile (SEP) questions 2 and 3, before and after the use of LC or placebo. Seventy-two men older than 18 years, with ED for at least 6 months with stable sexual relationship were enrolled. Patients were randomized to placebo or LC 80 mg, 40 mg, or 20 mg and followed for 4 weeks. IIEF erectile domain scores before and after the use of medications were (mean +/- standard deviation [SD]): placebo: 11.9 +/- 3.4 and 12.6 +/- 5.5; LC 20 mg: 15.8 +/- 4.1 and 18.9 +/- 6.6; LC 40 mg: 11.9 +/- 4.4 and 15.4 +/- 8.1; LC 80 mg: 14.2 +/- 4.7 and 22.8 +/- 6.0 (ANOVA P < 0.01). The SEP-2 scores before and after the use of medications were (Mean +/- SD): placebo: 71.0 +/- 33.1 and 51.2 +/- 43.1; LC 20 mg 70.3 +/- 34.2 and 75.5 +/- 31.5; LC 40 mg: 48.4 +/- 42.1 and 60.8 +/- 42.5; LC 80 mg: 68.6 +/- 33.5 and 89.6 +/- 26.0. The SEP-3 scores were: placebo 23.3 +/- 27.6 and 33.6 +/- 42.3; LC 20 mg: 32.3 +/- 38.9 and 51.2 +/- 41.7; LC 40 mg: 39.7 +/- 44.7 and 46.7 +/- 41.1; LC 80 mg* 17.2 +/- 29.5 and 74.3 +/- 36.4 (*P < 0.05 for difference to placebo). The drug was well tolerated. Adverse reactions were mild and self-limited and included headache, rhinitis, flushing, color visual disorders, and dyspepsia. This study showed that the dosage of 80 mg of LC was significantly more efficacious than placebo and well tolerated.

    Self-concept consists of self-perceptions and is influenced by the life course of the person. This study investigated associations between self-concept and erectile dysfunction (ED) in 45-year-old German men. Forty-five-year-old, heterosexual men who had participated in the PROBASE-study were included. Erectile Function was evaluated using the International Index of Erectile Function (IIEF-6). The presence of ED was defined by IIEF-6 score ≤ 25. Self-concept was assessed using the facets "body image" (three items from the Dresden Body Image Inventory, DKB-35), "perception of masculinity" (three items from the Male Role Norms Scale, MRNS), "perceived social pressure with regard to sexual performance" (four newly constructed items), and "sexual self-esteem" (three newly constructed items). Scores for these facets of self-concept can range from 1 to 5. Higher scores indicate a more positive body image, higher sexual self-esteem, a more modern understanding of masculinity, and greater perceived social pressure. Differences in self-concept between men with ED and without ED were analyzed using the Mann-Whitney-U-test. Furthermore, Cohen's d effect sizes (ES d) were calculated. The responses of 3143 men were analyzed. Men with ED (16.2 %) have significantly lower scores regarding body image (mean 3.6 ± 0.6 vs 3.8 ± 0.5; p self-esteem (mean 3.6 ± 0.6 vs 3.9 ± 0.5; p self-esteem, and greater perceived social pressure with regard to sexual performance than men without ED.

Aim of the present study was to investigate impact of metabolic syndrome (MetS) on association between psoriasis and ED as well as to improve our understanding of this association via studying other possible causes of ED such as psychological factors and disease effects. The patient group included 37 male psoriasis patients and control group 28 healthy men. Severity of psoriasis was determined using Psoriasis Area and Severity Index (PASI), and ED was evaluated using International Index of Erectile Function (IIEF) Scale. Psychiatric state of the patients were determined using Beck Depression Inventory (BDI). MetS was diagnosed using the National Cholesterol Education Program Adult Treatment Panel III criteria. MetS, ED prevalence and BDI score were significantly higher in psoriasis patient group (p = 0.032, p = 0.018 and p old age and smoking (but not MetS) were found to be independent predictors of ED. ED, MetS and depression frequencies were significantly higher in psoriasis patient group. In addition, psoriasis severity and ED parameters were closely associated. Depression, old age and smoking were found to be independent risk factors for ED.

    Full Text Available ABSTRACT Erectile dysfunction (ED is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5 questionnaire. Nocturnal penile tumescence (NPT testing confirmed the occurrence of ED in 96 (80% patients on whom penile duplex ultrasound and neurophysiological testing were further performed. Of these ED patients 29 (30% were demonstrated only with vascular abnormality, 41 (42.7% were detected only with neural abnormality, 26 (27.1% revealed mixed abnormalities. Of the 55 patients (29+26 with vascular problems, 7 patients (12.7% with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine, 31 (56.4% with corporal veno-occlusive dysfunction and 17 (30.9% had both problems. Of the 67 (41+26 patients with abnormal neurophysiological outcomes, 51 (76.1% with abnormal bulbocavernosus reflex (BCR, 20 (29.9% with pathological pudendal nerve evoked potentials (PDEPs and 25 (37.3% with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs. Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED.

    Despite the advent of effective oral therapies for erectile dysfunction (ED), many patients are not successfully treated, and side effects have been documented. To further evaluate the potential utility of naked DNA-based gene transfer as an attractive treatment option for ED. The effects of gene transfer on erectile function and sexual behavior were evaluated in eight male cynomolgus monkeys with ED secondary to moderately severe, diet-induced atherosclerosis. Following establishment of baseline characteristics, animals were subjected to intracavernous injection of a smooth-muscle-specific gene transfer vector (pSMAA-hSlo) encoding the pore-forming subunit of the human large-conductance, calcium-sensitive potassium channel (Maxi-K). For the sexual behavior studies, 2 wk of baseline data were obtained, and then animals were placed in the presence of estrogen-implanted females (n=2) three times per week for 30 min, and sexual behavior was recorded. The intracavernous pressure response to papaverine injection was also monitored. Dramatic changes in erectile function and sexual behavior were observed after intracorporal gene transfer. The frequency of partial (6±2 to 10±2) and full (2±1.5 to 5±1.4) erections were significantly increased, with a parallel 2-3-fold increase in the duration of the observed erections. The frequency and latency of ejaculation were increased and decreased, respectively. Frequency and duration of grooming by the female were increased, and the latency decreased. Increased latency and decreased frequency of body contact was also observed, and this is characteristic of the typical drop in consort intimacy that occurs after mating in most macaque species. In addition, an increased responsiveness to intracavernous papaverine injection was observed. The data indicate that intracorporal Maxi-K-channel gene transfer enhances erectile capacity and sexual behavior; the data imply that increased erectile function per se may lead to increased sexual

    Full Text Available Objectives: To review the cases of patients with suspected penile fracture and asses erectile and sexological outcomes. Materials and methods: from 1987 to 2013 presented to the Urology Clinic of Trieste and at the AIED of Pordenone a total of 41 cases that were divided into two groups according to the timing of treatment: 18 patients with anamnestic diagnosis of penile fracture treated nonimmediately and 23 patients treated immediately after the trauma. For all patients we evaluated the type of treatment adopted, the occurrence of complications and reoperations and the follow-up. The erectile function was also evaluated through the IIEF, as well as the psychological impact of the trauma on social and sex life, using a psycho- sexological questionnaire. Results: Among patients treated immediately after the trauma 14 were subjected to surgery. About a year after surgery, penile curvature was reported in 1 patient, pain in 3 patients, urinary disorders in 1 patient, while none reported erectile dysfunction (ED. Out of these, only 3 patients underwent reoperation. Among those treated conservatively 1 patient reported curvature, 1 patient reported pain and none reported ED. Among patients who were admitted at a later date, 14 reported curvature and 4 reported pain whereas urinary disorders were reported in 1 and ED in 4 patients. From a psychological point of view, the trauma caused in most cases a fear of new trauma and of repercussions on erectile function and sensitivity. Conclusions: The diagnosis is mainly clinical; however, radiological investigation is essential to confirm the diagnosis, assess the site and extent of the trauma and possible urethral involvement, so as to plan the most appropriate treatment. In addition, immediate treatment leads to better long-term results, with a lower incidence of ED and penile curvature. Psychologically, penile trauma intensifies the fear of reoccurrence; it decreases, however, with the passage of time.

    -free and subdivided into two arms according to treatment modality, either tadalafil three times/week or penile prosthesis implantation. All patients were evaluated using the International Index of Erectile Function (IIEF) questionnaire preoperatively and at 6, 12 and 24 month postoperatively. Repeated measurements analysis of variance was conducted to evaluate the effect of time and group on IIEF total score. There was a significant reduction in IIEF score from preoperative values to the first measurement after surgery in both treatment groups. The overall degree of change from the first time point immediately after surgery to 2 years was greater in the penile prosthesis group than the tadalafil group (20.4 ± 1.3 vs 8.1 ± 2.4, P < 0.001). The efficacy and satisfaction results of both treatment types are considered acceptable. However, regarding the erection frequency, firmness, penetration ability, maintenance and erection confidence it seems that penile prosthesis implantation is superior to oral treatment. The concept of early penile intervention should be considered and is promising for all patients with post-RRP erectile dysfunction. © 2012 BJU International.

    Globally, erectile dysfunction burden (ED) is rising appreciably and it is projected to affect about 332 million men by the year 2025. This rise is attributable to the rising incidence of conditions associated with ED including obesity, diabetes, hypertension, coronary artery disease and depression. We conducted this community-based screening to elucidate on the prevalence of ED and its associated factors among men residing in an urban community in Tanzania. We conducted a cross-sectional community-based study and interviewed 441 men aged at least 18 years. Diabetes and hypertension were defined as per the International Diabetes Federation (IDF) and the 7th Report of the Joint National Committee (JNC 7) respectively. The 5-item version of the International Index of Erectile Function (IIEF-5) Scale was used to assess for erectile dysfunction. Multivariate logistic regression analyses were performed to explore the factors associated with ED. The mean age was 47.1 years, 57.6 % had excess body weight, 8.2 % had diabetes and 61.5 % had high blood pressure. Overall, 24 % (106/441) of men in this study had some form of ED. Participants with age ≥55, positive smoking history, obesity, diabetes and hypertension displayed highest rates of ED in their respective subgroups. However, age ≥40 and diabetes were ultimately the strongest factors for ED after multivariate logistic regression analyses, (OR 5.0, 95 % CI 2.2-11.2, p Erectile dysfunction affects about a quarter of adult men living in Kinondoni district. Old age, obesity, smoking, hypertension and diabetes have the potential to increase the odds of ED up-to 5 times. In view of this, men with diabetes and hypertension should be offered screening services and treatment of ED as an integral component in their management.

    OBJECTIVE Patients with diabetic erectile dysfunction often have severe endothelial dysfunction and respond poorly to oral phosphodiesterase-5 inhibitors. We examined the effectiveness of the potent angiopoietin-1 (Ang1) variant, cartilage oligomeric matrix protein (COMP)-Ang1, in promoting cavernous endothelial regeneration and restoring erectile function in diabetic animals. RESEARCH DESIGN AND METHODS Four groups of mice were used: controls; streptozotocin (STZ)-induced diabetic mice; STZ-induced diabetic mice treated with repeated intracavernous injections of PBS; and STZ-induced diabetic mice treated with COMP-Ang1 protein (days −3 and 0). Two and 4 weeks after treatment, we measured erectile function by electrical stimulation of the cavernous nerve. The penis was harvested for histologic examinations, Western blot analysis, and cGMP quantification. We also performed a vascular permeability test. RESULTS Local delivery of the COMP-Ang1 protein significantly increased cavernous endothelial proliferation, endothelial nitric oxide (NO) synthase (NOS) phosphorylation, and cGMP expression compared with that in the untreated or PBS-treated STZ-induced diabetic group. The changes in the group that received COMP-Ang1 restored erectile function up to 4 weeks after treatment. Endothelial protective effects, such as marked decreases in the expression of p47phox and inducible NOS, in the generation of superoxide anion and nitrotyrosine, and in the number of apoptotic cells in the corpus cavernosum tissue, were noted in COMP-Ang1–treated STZ-induced diabetic mice. An intracavernous injection of COMP-Ang1 completely restored endothelial cell-cell junction proteins and decreased cavernous endothelial permeability. COMP-Ang1–induced promotion of cavernous angiogenesis and erectile function was abolished by the NOS inhibitor, N-nitro-L-arginine methyl ester, but not by the NADPH oxidase inhibitor, apocynin. CONCLUSIONS These findings support the concept of cavernous

    Type 2 diabetes mellitus (T2DM) is associated with endothelial dysfunction, characterized by a reduction of nitric oxide (NO)-mediated relaxation. Phosphodiesterase type 5 inhibitors (PDE5i) improve NO levels. The aim of the study was to investigate whether long-term, chronic treatment with the PDE5i vardenafil improves systemic endothelial function in diabetic men. A prospective, investigator-initiated, randomized, placebo-controlled, double-blind, clinical trial was conducted. In total, 54 male patients affected by T2DM, diagnosed within the last 5 years, and erectile dysfunction were enrolled, regardless of testosterone levels. In all, 26 and 28 patients were assigned to verum and placebo groups respectively. The study consisted of an enrollment phase, a treatment phase (24 weeks) (vardenafil/placebo 10  mg twice in a day) and a follow-up phase (24 weeks). Parameters evaluated were as follows: International Index of Erectile Function 15 (IIEF-15), flow-mediated dilation (FMD), serum interleukin 6 (IL6), endothelin 1 (ET-1), gonadotropins and testosterone (measured by liquid chromatography/tandem mass spectrometry). IIEF-15 erectile function improved during the treatment (Ptreatment both FMD (P=0.040) and IL6 (P=0.019) significantly improved. FMD correlated with serum testosterone levels (R(2)=0.299; Ptreatment and returned in the eugonadal range only in hypogonadal men (n=13), without changes in gonadotropins. Chronic vardenafil treatment did not result in relevant side effects. This is the first double-blind, placebo-controlled clinical trial designed to evaluate the effects of chronic treatment of vardenafil on endothelial health-related parameters and sexual hormones in patients affected by a chronic disease. Chronically administered vardenafil is effective and improves endothelial parameters in T2DM patient. Moreover, chronic vardenafil therapy improves hypogonadism in diabetic, hypogonadal men. © 2016 European Society of Endocrinology.

    To evaluate the prospective use of the thermography diagnostic system in assessing sexual function in patients with erectile dysfunction (ED). Thermographs were taken on 14 subjects in a clinical trial conducted at Tan Tock Seng Hospital. After a thorough clinical interview with a standardized questionnaire, patients were scanned for baseline temperature profile before being given an oral dose of sildenafil 100 mg. Subjects were scanned again in the same setting an hour later. If so desired, subjects were given visual stimulation and were allowed minimum direct stimulation, excluding the penis, to elicit erection. Temperature profiles were analyzed using the thermography analysis software in the VarioCAM camera. Three representative cases are presented to illustrate the potential for using the Infrared thermography (IR) diagnostic system in differentiating psychogenic ED. IR was able to capture a significant difference in blood flow to the corpus cavernosum. Subjects with psychogenic ED have higher surface temperatures (34.3 degrees C +/- 0.71 in the flaccid state and 35.3 degrees C +/- 0.2 during erection) compared to subjects with organic ED (33.64 degrees C +/- 0.4 in flaccid and 33.55 degrees C +/- 0.91 during erection). The difference in surface temperature between flaccid and erected states in subjects with organic ED was not significant. The proposed diagnostic test based on IR has tremendous clinical potential in differentiating psychogenic ED from organic ED. IR could potentially be a portable, noninvasive and convenient adjunct in the diagnosis and management of ED.

    Full Text Available To investigate the therapeutic effect of different doses of low energy shock wave therapy (LESWT on the erectile dysfunction (ED in streptozotocin (STZ induced diabetic rats. SD rats (n = 75 were randomly divided into 5 groups (normal control, diabetic control, 3 different dose LESWT treated diabetic groups. Diabetic rats were induced by intra-peritoneal injection of STZ (60 mg/kg and rats with fasting blood glucose ≥ 300 mg/dL were selected as diabetic models. Twelve weeks later, different doses of LESWT (100, 200 and 300 shocks each time treatment on penises were used to treat ED (7.33 MPa, 2 shocks/s three times a week for two weeks. The erectile function was evaluated by intracavernous pressure (ICP after 1 week washout period. Then the penises were harvested for histological study. The results showed LESWT could significantly improve the erectile function of diabetic rats, increase smooth muscle and endothelial contents, up-regulate the expression of α-SMA, vWF, nNOS and VEGF, and down- regulate the expression of RAGE in corpus cavernosum. The therapeutic effect might relate to treatment dose positively, and the maximal therapeutic effect was noted in the LESWT300 group. Consequently, 300 shocks each time might be the ideal LESWT dose for diabetic ED treatment.

    Satisfaction with the sexual experience is considered important when evaluating the impact of treatments for erectile dysfunction, yet enhanced satisfaction has been infrequently assessed in the sexual trials. We evaluated the efficacy of sildenafil vs. tadalafil, in Saudi men with erectile dysfunction and determined the self-based rating of medicinal preference. Sildenafil citrate (Viagra) is a potent inhibitor of the electrolytic enzyme type V phosphodiesterase (PDE5), in the corpus cavernosum and therefore increases the penile response to sexual stimulation. Tadalafil (Cialis) is also a PDE5 inhibitor that increases the level of cyclic guanosine monophosphate (cGMP) in cavernous smooth muscle cells. Whereas cGMP is a second messenger for the vasodilator effects of nitric oxide causing smooth muscle relaxation, which in turn leads to penile erection; however the mechanism by which cGMP stimulates relaxation of the smooth muscles remains to be elucidated. Both sildenafil and tadalafil have a rapid onset with the effectiveness up to 4 hours and 36 hours respectively. In this study subjects treated with 100 mg oral dose of sildenafil / 20 mg tadalafil were found to be associated with higher mean scores for the questions of the International Index of Erectile Function (IIEF). Frequency of penetration and maintenance of erection after sexual penetration and/or during masturbation were found to be enhanced significantly (p<0.001) in both sildenafil/tadalafil treated men. Similarly mean domain of erectile function, orgasmic function, and intercourse satisfaction also showed a significantly positive improvement (p/0.001) in both the treated groups in comparison with their age matched untreated controls. Interestingly in all the cases, tadalafil group showed considerably greater positive responses than the sildenafil group but within the same significant levels. Strikingly the sexual-desire domain in sildenafil treated men with respect to their aged matched controls

    Given the paucity of literature on the time course of recovery of erectile function (EF) after radical prostatectomy (RP), many publications have led patients and clinicians to believe that erections are unlikely to recover beyond 2 years after RP. We sought to determine the time course of recovery of EF beyond 2 years after bilateral nerve sparing (BNS) RP and to determine factors predictive of continued improved recovery beyond 2 years. EF was assessed prospectively on a 5-point scale: (i) full erections; (ii) diminished erections routinely sufficient for intercourse; (iii) partial erections occasionally satisfactory for intercourse; (iv) partial erections unsatisfactory for intercourse; and (v) no erections. From 01/1999 to 01/2007, 136 preoperatively potent (levels 1-2) men who underwent BNS RP without prior treatment and who had not recovered consistently functional erections (levels 1-2) at 24 months had further follow-up regarding EF. Median follow-up after the 2-year visit was 36.0 months. Recovery of improved erections at a later date: recovery of EF level 1-2 in those with level 3 EF at 2 years and recovery of EF level 1-3 in those with level 4-5 EF at 2 years. The actuarial rates of further improved recovery of EF to level 1-2 in those with level 3 EF at 2 years and to level 1-3 in those with level 4-5 EF at 2 years were 8%, 20%, and 23% at 3, 4, and 5 years postoperatively, and 5%, 17%, and 21% at 3, 4, and 5 years postoperatively, respectively. Younger age was predictive of greater likelihood of recovery beyond 2 years. There is continued improvement in EF beyond 2 years after BNS RP. Discussion of this prolonged time course of recovery may allow patients to have a more realistic expectation. © 2010 International Society for Sexual Medicine.

    Erectile dysfunction (ED) is especially common in men with cardiovascular diseases (CVDs). However, the data are scarce concerning populations without manifested CVD. The aim of this study was to describe factors associated with ED, especially those associated with decreasing risk of ED, in men with cardiovascular risk factors but without CVD, diabetes, or chronic renal disease. In 2004 to 2007, a cross-sectional population-based sample of men 45 to 70 years old in two rural towns in Finland was collected. Men with previously diagnosed CVD, diabetes, or kidney disease were not invited to the study. In total 1,000 eligible men with cardiovascular risk factors, i.e., central obesity, high scores in the Finnish Diabetes Risk Score, high blood pressure, antihypertensive medication, or family history of coronary heart disease, myocardial infarction, or stroke, were included in the analysis. Questionnaires, clinical measurements, and laboratory tests were obtained. The prevalence of ED was studied comparing the means, and risk factors were studied using multivariate logistic regression analysis. The rate of ED was defined by the International Index of Erectile Function short form (IIEF-5) and by two questions (2Q) about the ability to achieve and to maintain an erection. The prevalence of ED was 57% or 68% using IIEF-5 or 2Q, respectively. Age (odds ratio [OR]: up to 9.16; 95% confidence interval [CI], 5.00-16.79; P physical activity (OR: 0.50; 95% CI, 0.29-0.86; P = 0.045), high education (OR: 0.52; 95% CI, 0.33-0.83; P = 0.013), and stable relationship (OR: 0.43; 95% CI, 0.21-0.88; P = 0.046) were associated with ED. In apparently healthy men with cardiovascular risk factors, decreasing risk of ED is associated with high-intensity physical activity, stable relationship, and high education level. © 2014 International Society for Sexual Medicine.

    Obesity has been receiving an increasing amount of attention recently, but investigations regarding the potential impact of obesity, sexual behaviors, and sex hormones on erectile dysfunction (ED) in men have not completely clarified the association. To identify the relationship between ED, sexual behavior, sexual satisfaction, sex hormones, and obesity in older adult males in Taiwan. Data were obtained from a baseline survey of 476 older adult males (≧40 years old). Their demographic data, body mass index (BMI), sex hormones, sexual desire, sexual satisfaction, and ED status were assessed. The International Index of Erectile Function-5 (IIEF-5), Sexual Desire Inventory (SDI), and Sexual Satisfaction Scale (SSS) were used to assess ED, sexual desire, and sexual satisfaction. In all, 476 men were available for analysis. The mean age of the sample was 51.34 ± 7.84 years (range 40 to 70 years). The IIEF total score had a mean of 19.44 ± 4.98; 264 (55.5%) subjects had ED, 250 (52.9%) were currently obese (BMI ≧27), and 297 (62.4%) had metabolic syndrome. The results showed an increased risk of ED among obese men and subjects with lower levels of sex hormones and lower sexual desire. Testosterone levels were lower in subjects with obesity (P < 0.001). Among the predictors of ED, obesity (odds ratio [OR] = 1.62, 95% CI = 1.07-2.44, P = 0.021), abnormal high sensitivity C-reactive protein (hs-CRP) (OR = 10.59, 95% CI = 4.70-23.87, P < 0.001), and lower serum full testosterone (OR = 3.27, 95% CI = 2.16-4.93, P < 0.001) were significantly independent factors. This study supports the idea of a close relationship between low levels of sex hormones, sexual desire, sexual satisfaction, obesity, and ED, and also shows that low free testosterone and hs-CRP may predict ED, even in obese populations. © 2013 International Society for Sexual Medicine.

    Full Text Available In this study, we present a biofeedback method for the strengthening of perineal muscles during the preoperative procedures for radical prostatectomy, and we evaluate this technique as a prevention measure against complications such as urinary incontinence (UI and erectile dysfunction (ED, which affect prostatectomy patients after surgery. In the experimental protocol, the patients performed specific exercises with the help of a device that provided the patient with visual biofeedback, based on a plot of the anal pressure. For the experimental protocol, we selected 20 male patients, with an average age of 64.0 years, and submitted them to ten therapeutic sessions each. A control group consisting of 32 men with an average age of 66.3 years, who were treated with the same surgical procedure but not with the preoperative procedures, also took part in the experiment. To evaluate UI and ED after the surgery in both control and experimental groups, we used two validated questionnaires—to assess UI, we used the King’s Health Questionnaire (KHQ and, for ED, we used the International Index of Erectile Function (IIEF-5 Questionnaire. We compared the variables associated with UI and ED after the surgery for the control and experimental groups. The occurrence of UI after radical prostatectomy in the control group (100% of the patients was higher than that for the experimental group (5% of the patients, with p < 0.0001. Likewise, the occurrence of erectile dysfunction after prostatectomy in the control group (48.6% of the patients was higher than that for the experimental group (5% of the patients, with p < 0.0001. The number of nocturia events also decreased as a consequence of the intervention (p < 0.0001, as did the number of disposable underwear units for urinary incontinence (p < 0.0001. Furthermore, we compared, only for the experimental group, the anal pressure before the biofeedback intervention and after the surgery, and we

    Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is an independent risk factor for the development of erectile dysfunction (ED). But the molecular mechanisms underlying the relationship between CP/CPPS and ED are still unclear. The aim of this study was to investigate the effect of CP/CPPS on erectile function in a rat model and the possible mechanisms. A rat model of experimental autoimmune prostatitis (EAP) was established to mimic human CP⁄CPPS. Then twenty 2-month-old male Sprague-Dawley rats were divided into EAP group and control group. Intracavernosal pressure (ICP) and mean arterial pressure (MAP) were measured during cavernous nerve electrostimulation, the ratio of max ICP/MAP was calculated. Blood was collected to measure the levels of serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and testosterone, respectively. The expression of endothelial nitric oxide synthase (eNOS), cyclic guanosine monophosphate (cGMP) levels, superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels in corpus cavernosum were detected. We also evaluated the smooth muscle/collagen ratio and apoptotic index (AI). The ratio of max ICP/MAP in EAP group were significantly lower than that in control group. The levels of serum CRP, TNF-α, IL-1β, and IL-6 in EAP group were all significantly higher than these in control group. The expression of eNOS and cGMP levels in corpus cavernosum of EAP rats were significantly downregulated. Furthermore, decreased SOD activity and smooth muscle/collagen ratio, increased MDA levels and AI were found in corpus cavernosum of EAP rats. In conclusion, CP/CPPS impaired penile erectile function in a rat model. The declines of eNOS expression and cGMP levels in corpus cavernosum may be an important mechanism of CP/CPPS-induced ED. CP/CPPS also increased oxidative stress, cell apoptosis and decreased smooth muscle/collagen ratio in corpus cavernosum of rats, which were

    Full Text Available The premature ejaculation diagnostic tool (PEDT is a brief diagnostic measure to assess premature ejaculation (PE. However, there is insufficient evidence regarding its validity in the new evidence-based-defined PE. This study was performed to evaluate the validity of PEDT and its association with IIEF-15 in different types of evidence-based-defined PE. From June 2015 to January 2016, a total of 260 men complaining of PE and defined as lifelong PE (LPE/acquired PE (APE according to the evidence-based definition from Andrology Clinic of the First Affiliated Hospital of Anhui Medical University, along with 104 male healthy controls without PE from a medical examination center, were enrolled in this study. All individuals completed questionnaires including demographics, medical and sexual history, as well as PEDT and IIEF-15. After statistical analysis, it was found that men with PE reported higher PEDT scores (14.28 ± 3.05 and lower IIEF-15 (41.26 ± 8.20 than men without PE (PEDT: 5.32 ± 3.42, IIEF-15: 52.66 ± 6.86, P < 0.001 for both. It was suggested that a score of ≥9 indicated PE in both LPE and APE by sensitivity and specificity analyses (sensitivity: 0.875, 0.913; specificity: 0.865, 0.865, respectively. In addition, IIEF-15 were higher in men with LPE (42.64 ± 8.11 than APE (39.43 ± 7.84, P < 0.001. After adjusting for age, IIEF-15 was negatively related to PEDT in men with LPE (adjust r = −0.225, P < 0.001 and APE (adjust r = −0.378, P < 0.001. In this study, we concluded that PEDT was valid in the diagnosis of evidenced-based-defined PE. Furthermore, IIEF-15 was negatively related to PEDT in men with different types of PE.

    Background Intracavernous (IC) injection of stem cells has been shown to ameliorate cavernous-nerve (CN) injury-induced erectile dysfunction (ED). However, the mechanisms of action of adipose-derived stem cells (ADSC) remain unclear. Objectives To investigate the mechanism of action and fate of IC injected ADSC in a rat model of CN crush injury. Design, setting, and participants Sprague-Dawley rats (n = 110) were randomly divided into five groups. Thirty-five rats underwent sham surgery and IC injection of ADSC (n = 25) or vehicle (n = 10). Another 75 rats underwent bilateral CN crush injury and were treated with vehicle or ADSC injected either IC or in the dorsal penile perineural space. At 1, 3, 7 (n = 5), and 28 d (n = 10) postsurgery, penile tissues and major pelvic ganglia (MPG) were harvested for histology. ADSC were labeled with 5-ethynyl-2-deoxyuridine (EdU) before treatment. Rats in the 28-d groups were examined for erectile function prior to tissue harvest. Measurements IC pressure recording on CN electrostimulation, immunohistochemistry of the penis and the MPG, and number of EdU-positive (EdU+) cells in the injection site and the MPG. Results and limitations IC, but not perineural, injection of ADSC resulted in significantly improved erectile function. Significantly more EdU+ ADSC appeared in the MPG of animals with CN injury and IC injection of ADSC compared with those injected perineurally and those in the sham group. One day after crush injury, stromal cell-derived factor-1 (SDF-1) was upregulated in the MPG, providing an incentive for ADSC recruitment toward the MPG. Neuroregeneration was observed in the group that underwent IC injection of ADSC, and IC ADSC treatment had beneficial effects on the smooth muscle/collagen ratio in the corpus cavernosum. Conclusions CN injury upregulates SDF-1 expression in the MPG and thereby attracts intracavernously injected ADSC. At the MPG, ADSC exert neuroregenerative effects on the cell bodies of injured nerves

    Erectile dysfunction (ED) is a serious burden globally that affects men as well as their partners. Therefore, the aim of this study was to determine the prevalence and predictors of ED among male outpatient clinic attendees in Johor, Malaysia. A cross-sectional study of Malaysian men aged 18 and older attending two major outpatient clinics in Johor Bahru and Segamat between 1 January and 31 March 2016 was undertaken. Subjects were chosen via simple random sampling and a sample size of 400 was recruited. The study instrument was a survey form that consisted of three sections: sociodemographic and comorbid profile, validated English and Malay version of the 15-item International Index of Erectile Function (IIEF-15) and 21-item Depression Anxiety and Stress Scale (DASS-21). The overall prevalence of self-reported ED was 81.5%. The prevalence of ED according to severity was as follows: mild (17%), mild to moderate (23.8%), moderate (11.3%), and severe (29.5%). Multivariate analysis showed that ED was associated with increasing age (odds ratio [OR] 4.023, 95% confidence interval [CI] 1.633-9.913), Indians as compared to Malays (OR 3.252, 95% CI 1.280-8.262), secondary as compared to tertiary education (OR 2.171, 95% CI 1.203-3.919), single as compared to married status (OR 6.119, 95% CI 2.542-14.734), and stress (OR 4.259, 95% CI 1.793-10.114). There is significant prevalence and severity of ED among adult male outpatient clinic attendees in Johor. Increasing age, Indian ethnicity, lower educational level, being single, and stress were significant predictors of ED.

    Full Text Available The behavior of Chinese patients seeking help for erectile dysfunction (ED has not been described in detail. This was an observational study conducted using an outpatient clinic-based questionnaire survey of ED patients. From 2008 to 2009, physicians in 10 medical centers in China enrolled 2693 men (aged 25-70 years diagnosed with ED. The diagnosis was based on the International Index of Erectile Function 5 (IIEF-5 Questionnaire. The men completed a survey that asked questions about demographics, marital status, education level and household income as well as help-seeking behavior and awareness of medical therapy. The mean age of the 2693 men was 43.4 ± 5.3 years; 73% were <50-years-old and 49% had a high household income. The mean time between noticing ED and taking the first treatment was 4.3 ± 2.1 months. Of the 2577 respondents, physicians (54% and the internet (52% were most frequently consulted sources for information about ED. Young ED patients preferred using the internet and older patients preferred consulting with physicians. Western medicine (19% and traditional Chinese medicine (16% were most frequently used for treatment. Young ED patients preferred to first search the internet for information, whereas older patients first asked physicians for help. Side effects of treatment were the greatest concern, especially for older patients. Physicians and the internet are frequently consulted for ED information and therapy. On the basis of these survey results, we believe that physicians in China should enhance health education about ED, especially via the internet.

    In this paper, we describe the development and clinical application of the Rejuvenator and report the result of our study on its mechanism for the treatment of functional erectile dysfunction (FED). The Rejuvenator, which can be used both at home and in hospitals to treat patients with FED, was developed on the basis of our clinical practice in the light of the modern theory of traditional Chinese medicine and by integrating multiple techniques of engineering science. It works by means of the paraoral use of the special herbal medicine, electro-magnetic effects, thermal moxibustion and drug-ingression. 2250 patients with FED received the treatment. Using combined electro-neurophysiological techniques, pulsed ultrasound Doppler and microcomputer image-scanning, we further studied the mechanism of the Rejuvenator for the treatment of FED. The total effective rate was 92%. The clinical data and result of study indicate that the Rejuvenator for the patients with functional erectile dysfunction is a safe, effective and scientific new method.

    Full Text Available Abstract Introduction Sildenafil (Viagra® is one of the drugs used in the first line therapy of male erectile dysfunction (MED. We have recorded outcomes, adverse events and acceptability of Sildenafil (Viagra therapy in an unselected group of men presenting with ED to a British district general hospital. Methods In this prospective observational study, 147 men with ED were seen since Oct 1999. Study patients were reviewed at 4, 12 and 52 weeks. All the patients filled the International Index of Erectile Function (IIEF questionnaire and were asked about their willingness to pay (WTP for treatment. Results All suitable men accepted Viagra as first line therapy. 91% of our patients found sildenafil treatment successful. 80% of these patients were willing to continue with sildenafil therapy. Side effect profile of sildenafil was different in this study with much higher incidence of headache, dyspepsia, flushing and abnormal vision. 92% of men with ED expect to be treated by the NHS. Of those men eligible for treatment in the NHS, 30% qualify under the clinical categories and 18% under the 'distress' category. Only 55% of those with cardiovascular risk factors qualify for NHS treatment. Conclusions Sildenafil is widely accepted as first line therapy among British men with ED and has a success rate of 91%. Nearly half of men with ED qualify for NHS treatment. Nearly half of those with vascular risk factors do not qualify for NHS treatment. Most men with ED could possibly be managed in primary care.

    Erectile dysfunction (ED) is observed frequently in patients with end-stage renal disease, hemodialysis patients, and renal allograft recipients. There are few studies of sildenafil use in renal allograft recipients. The study is designed as a randomized, double-blind, placebo-controlled, crossover trial. Efficacy was assessed by using the self-administered International Index of Erectile Function (IIEF), a 15-question validated measure of ED, and a global efficacy question (Did the treatment improve your erection?). Thirty-two eligible renal transplant recipients were included in this study. After treatment with sildenafil citrate, patients had significantly better scores in 13 of 15 questions, except for questions 11 (desire frequency; P = 0.39) and 12 (desire level; P = 0.61). Treatment efficacy assessed through questions 3 (penetration ability; P satisfaction). Patients treated with sildenafil had significantly better scores in 4 domains compared with baseline, but a difference was not observed in the sexual desire domain (P = 0.32). There were no significant differences in scores between placebo and baseline in any domain. On the global efficacy question, 81.3% of patients showed improvement compared with 18.7% with placebo. There were no differences in areas under the curve and maximum cyclosporine concentrations before and after sildenafil therapy. No patient discontinued the drug because of side effects except for 1 patient with visual hallucination. Treatment with sildenafil in renal transplant recipients is a valid option with an effective response.

    Erectile dysfunction (ED) can significantly impact a man's relationships and well-being. We assessed changes in self-esteem, confidence, sexual relationship satisfaction, and overall relationship satisfaction in men with ED using the validated Self-Esteem And Relationship questionnaire (SEAR). This was a 12-week, double-blind, placebo-controlled, flexible-dose (25, 50, 100 mg, as needed) international study of sildenafil in men > or =18 years of age in Mexico, Brazil, Australia, and Japan. The primary study outcome was change in self-esteem from baseline to the end of treatment. Secondary study measures were changes in other SEAR components, International Index of Erectile Function (IIEF) domains, percentage of intercourse attempts that were successful, and the response to a global efficacy question at the end of treatment. Patients were well balanced for age and duration of ED (placebo = 149 and sildenafil = 151). Compared with placebo, sildenafil significantly improved self-esteem, confidence, sexual relationship satisfaction, and overall relationship satisfaction (P relationship satisfaction, and overall relationship satisfaction after treatment of ED with sildenafil were consistent among countries. These data suggest a substantial cross-cultural improvement in well-being after successful treatment of ED with sildenafil.

    The prevalence of erectile dysfunction (ED) is substantial and continues to rise. Current therapeutics for ED consist of oral medications, intracavernosal injections, vacuum erection devices, and penile implants. While such options may manage the disease state, none of these modalities, however, restore function. Stem cell therapy has been evaluated for erectile restoration in animal models. These cells have been derived from multiple tissues, have varied potential, and may function via local engraftment or paracrine signaling. Bone marrow-derived stem cells (BMSC) and adipose-derived stem cells (ASC) have both been used in these models with noteworthy effects. Herein, we will review the pathophysiology of ED, animal models, current and novel stem-cell based therapeutics, clinical trials and areas for future research. The relevant literature and contemporary data using keywords, "stem cells and erectile dysfunction" was reviewed. Examination of evidence supporting the association between erectile dysfunction and adipose derived stem cells, bone marrow derived stem cells, placental stem cells, urine stem cells and stem cell therapy respectively. Placental-derived stem cells and urine-derived stem cells possess many similar properties as BMSC and ASC, but the methods of acquisition are favorable. Human clinical trials have already demonstrated successful use of stem cells for improvement of erectile function. The future of stem cell research is constantly being evaluated, although, the evidence suggests a place for stem cells in erectile dysfunction therapeutics. Matz EL, Terlecki R, Zhang Y, et al.

    Erectile dysfunction (ED) continues to be a significant problem for men following radical prostatectomy. We hypothesize that intracavernous injection of BDNF-hypersecreting human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) can ameliorate ED in a rat model of cavernous nerve electrocautery injury (CNEI). Forty-two male Sprague-Dawley rats were randomly divided into four groups: sham + PBS (n = 6), CNEI + PBS (n = 12), CNEI + hUCB-MSCs (n = 12) and CNEI + BDNF-hUCB-MSCs (n = 12). At day 28 post-surgery, erectile function was examined and specimens were harvested for histology. Immunofluorescence staining, Masson's trichrome staining and transmission electron microscopy were performed to determine the structural changes in corpus cavernosum. Cells that are injected into penis were labeled by BrdU and tracked by immunofluorescence staining. Three days post-surgery, the concentration of BDNF protein in penile tissues was measured by Western blotting. Rats intracavernosally injected with BDNF-hUCB-MSCs showed the most significant improvement in the ratio of maximal ICP to MAP (ICP/MAP). Histological examinations showed moderate recovery of nNOS-positive nerve fibers, ratio of smooth muscle to collagen and smooth muscle content in the CNEI + hUCB-MSCs group and remarkable recovery in the CNEI + BDNF-hUCB-MSCs group compared to the CNEI + PBS group. By TEM examination, atrophy of myelinated and non-myelinated nerve fibers was noted in CNEI + PBS group and significant recovery was observed in two treated groups. There were more BrdU-positive cells in the BDNF-hUCB-MSCs group than in the hUCB-MSCs group both in the penis and in the MPG. Three days post-surgery, the concentration of BDNF protein in penile tissues in BDNF-hUCB-MSCs group was much higher than in other groups. Intracavernous injection of BDNF-hypersecreting hUCB-MSCs can enhance the recovery of erectile function, promote the CNs regeneration and inhibit corpus cavernosum fibrosis after CNEI in a rat

    To assess the long-term effect of Mediterranean diet, as compared with low-fat diet, on sexual function in patients with newly diagnosed type 2 diabetes. In a randomized clinical trial, with a total follow-up of 8.1years, 215 men and women with newly diagnosed type 2 diabetes were assigned to Mediterranean diet (n=108) or a low-fat diet (n=107). The primary outcome measures were changes of erectile function (IIEF) in diabetic men and of female sexual function (FSFI) in diabetic women. There was no difference in baseline sexual function in men (n=54 vs 52) or women (n=54 vs 55) randomized to Mediterranean diet or low-fat diet, respectively (P=0.287, P=0.815). Over the entire follow-up, the changes of the primary outcomes were significantly lower in the Mediterranean diet group compared with the low-fat group: IIEF and FSFI showed a significantly lesser decrease (1.22 and 1.18, respectively, P=0.024 and 0.019) with the Mediterranean diet. Baseline C-reactive protein levels predicted erectile dysfunction in men but not female sexual dysfunction in women. Among persons with newly diagnosed type 2 diabetes, a Mediterranean diet reduced the deterioration of sexual function over time in both sexes. Copyright © 2016 Elsevier Inc. All rights reserved.

    In Australia, four formal F-111 fuel tank deseal/reseal (DSRS) repair programs were implemented over more than two decades, each involving different processes and using a range of hazardous substances. However, health concerns were raised by a number of workers. The "Study of Health Outcomes in Aircraft Maintenance Personnel" was commissioned by the Australian Department of Defence to investigate potential adverse health outcomes as a result of being involved in the deseal/reseal processes. To compare measures of sexual function in F-111 aircraft fuel tank DSRS maintenance workers, against two appropriate comparison groups. Exposed and comparison participants completed a postal questionnaire which included general questions of health and health behavior, and two specific questions on sexual functioning. They also completed the International Index of Erectile Function (IIEF) questionnaire. Logistic regression was used to explore exposure status and outcome while adjusting for potential confounders. The three outcomes of interest for this study were the proportion of participants with erectile dysfunction (ED) according to the IIEF, the proportion with self-reported loss of interest in sex, and the proportion with self-reported problems with sexual functioning. Compared with each of the comparison groups, a larger proportion of the exposed group reported sexual problems and were classified as having ED according to the IIEF. In logistic regression, the odds of all three outcomes were higher for exposed participants relative to each comparison group and after adjustment for potentially confounding variables including anxiety and depression. There was a consistent problem with sexual functioning in the exposed group that is not explained by anxiety and depression, and it appears related to DSRS activities.

METHODS—Twenty four patients with erectile disease were recruited, 12 with Parkinson's disease and 12 with multiple system atrophy, into a randomised, double blind, placebo controlled, crossover study of sildenafil citrate. The starting dose was 50 mg active or placebo medication with the opportunity for dose adjustment depending on efficacy and tolerability. The international index of erectile function questionnaire (IIEF) was used to assess treatment efficacy and a quality of life questionnaire to assess the effect of treatment on sex life and whole life. Criteria for entry included a definite neurological diagnosis and a standing systolic blood pressure of 90-180 mm Hg and diastolic blood pressure of 50-110 mm Hg, on treatment if necessary. Blood pressure was taken at randomisation (visit 2) and crossover (visit 5) lying, sitting, and standing, before and 1 hour after taking the study medication in hospital.
RESULTS—Sidenafil citrate was efficacious in men with parkinsonism with a significant improvement, as demonstrated in questionnaire responses, in ability to achieve and maintain an erection and improvement in quality of sex life. In Parkinson's disease there was minimal change in blood pressure between active and placebo medication. In multiple system atrophy, six patients were studied before recruitment was stopped because three men showed a severe drop in blood pressure 1 hour after taking the active medication. Two were already known to have orthostatic hypotension and were receiving treatment with ephedrine and midodrine but the third had asymptomatic hypotension. However, the blood pressures in all three had been within the inclusion criterion for the study protocol. Despite a significant postural fall in blood pressure after sildenafil, all patients with

    Purpose: To determine the incidence of potency preservation following permanent prostate brachytherapy and to evaluate the effect of multiple clinical and treatment parameters on penile erectile function. Materials and Methods: 425 patients underwent permanent prostate brachytherapy from April 1995 to October 1999. 209 patients who were potent prior to brachytherapy and currently not receiving hormonal manipulation were mailed an International Index of Erectile Function (IIEF) questionnaire with a pre-addressed stamped envelope. 180 patients completed and returned the questionnaire. Median patient follow-up was 39 months (range 18-74 months). Pre-implant erectile function was assigned using a three-tiered scoring system (2 = erections always or nearly always sufficient for vaginal penetration; 1 = erections sufficient for vaginal penetration but considered suboptimal; 0 = the inability to obtain erections and/or erections inadequate for vaginal penetration). Post-implant potency was defined as an IIEF score >11. Clinical parameters evaluated for sexual function included patient age, clinical T stage, elapsed time since implantation, hypertension, diabetes mellitus, and tobacco consumption. Evaluated treatment parameters included the utilization of neoadjuvant hormonal manipulation and the choice of isotope. The efficacy of sildenafil citrate in brachytherapy induced erectile dysfunction (ED) was also evaluated. Results: A pre-treatment erectile function score of 2 and 1 were assigned to 126 and 54 patients respectively. With 6 year follow up, 39% of patients maintained potency following prostate brachytherapy with a plateau on the curve. Post-implant preservation of potency (IIEF>11) correlated with pre-implant erectile function (50% versus 14% for pre-implant scores of 2 and 1 respectively, p≤0.0001), patient age (56%, 38%, and 23% for patients <60 years of age, 60-69 years of age, and ≥70 years of age respectively, p=0.012) and a history of diabetes mellitus

    Men with alcohol dependence (AD) commonly suffer from alcohol-induced sexual (erectile) dysfunction (ED) and have poor quality of life (Qol). Knowledge about the factors associated with Qol in such patients is lacking. To identify in men who sought medical help for both AD and ED the variables that best predicted feelings of satisfaction with life and with specific life domains. The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q). Secondary study measures were the International Index of Erectile Function (IIEF), Beck Depression Inventory (BDI-13), General Health Questionnaire (GHQ-12), Rosenberg's General Self-Esteem Scale (RGSES), and the Multidimensional Scale of Perceived Social Support (MSPSS). Within an open-label sildenafil trial, 101 men aged 18-50 years with an International Classification of Diseases, Tenth Edition diagnosis of AD and concomitant ED were interviewed and completed the questionnaires. Multivariate analyses were applied to establish predictors of life satisfaction and factors mediating the relation between ED and life satisfaction. ED and self-rated depressive symptoms, emotional distress, self-esteem, and perceived social support were found to be significantly associated with Qol and its component domains. Altogether they explained 18-38% of the variance in the Qol ratings. Depressive symptomatology, distress, and self-esteem, individually, demonstrated a mediating effect on the relation between ED and Qol. Finally, self-esteem was shown to be the primary mediator in this relationship. The results of the study show that self-esteem is the primary factor, and depressive symptoms and severe emotional distress are secondary factors mediating the effects of ED on Qol in male patients seeking medical help for both AD and ED. An integrated pharmacopsychosocial approach targeting the underlying ED as well as the mediating emotional conditions could improve Qol of these patients and thus help them to stop using alcohol.

    Full Text Available In the current era of the early diagnosis of prostate cancer (PCa and the development of minimally invasive surgical techniques, erectile dysfunction (ED represents an important issue, with up to 68% of patients who undergo radical prostatectomy (RP complaining of postoperative erectile function (EF impairment. In this context, it is crucial to comprehensively consider all factors possibly associated with the prevention of post-RP ED throughout the entire clinical management of PCa patients. A careful assessment of both oncological and functional baseline characteristics should be carried out for each patient preoperatively. Baseline EF, together with age and the overall burden of comorbidities, has been strongly associated with the chance of post-RP EF recovery. With this goal in mind, internationally validated psychometric instruments are preferable for ensuring proper baseline EF evaluations, and questionnaires should be administered at the proper time before surgery. Careful preoperative counselling is also required, both to respect the patient’s wishes and to avoid false expectations regarding eventual recovery of baseline EF. The advent of robotic surgery has led to improvements in the knowledge of prostate surgical anatomy, as reflected by the formal redefinition of nerve-sparing techniques. Overall, comparative studies have shown significantly better EF outcomes for robotic RP than for open techniques, although data from prospective trials have not always been consistent. Preclinical data and several prospective randomized trials have demonstrated the value of treating patients with oral phosphodiesterase 5 inhibitors (PDE5is after surgery, with the concomitant potential benefit of early re-oxygenation of the erectile tissue, which appears to be crucial for avoiding the eventual penile structural changes that are associated with postoperative neuropraxia and ultimately result in severe ED. For patients who do not properly respond to

    To evaluate the serial changes in sexual function in the short-term period after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH) and to investigate whether a change in each domain of the International Index of Erectile Function (IIEF) is associated with improvement of micturition. Thirty-eight potent men who underwent HoLEP and in whom complete 12-month follow-up data on the IIEF were available were included in this retrospective study. All patients underwent a baseline evaluation for BPH. The surgical outcome was evaluated at 1, 3, 6, and 12 months postoperatively by use of the International Prostate Symptom Score, IIEF, and uroflowmetry. The mean age and body mass index of the patients was 64.5±6.2 years and 24.2±2.6 kg/m(2), respectively. Mean total prostate volume and transitional zone volume were 48.8±18.8 ml and 24.2±16.1 ml, respectively. Most IIEF domain scores showed a slight decrease at 1, 3, and 6 months after surgery but recovered to the baseline or showed a marginal but nonsignificant increase at 12 months postoperatively compared with baseline. Orgasmic function and the overall sexual satisfaction domain score remained slightly reduced up to 12 months postoperatively. There was no significant correlation between improvement of micturition and change in sexual function throughout the follow-up period after surgery. Although HoLEP achieves significant improvements in micturition, overall sexual function decreases slightly in the early postoperative period, but recovers to the baseline at 12 months postoperatively. Our data suggest that changes in sexual function after HoLEP are not associated with improvement of micturition.

    The aim of this study was to investigate sexual function and the presence of lower urinary tract symptoms (LUTS) in male patients with rectal cancer following short-term radiotherapy and laparoscopic total mesorectal excision (LTME) by physical and psychological measurements. Sexual function and LUTS were assessed by the use of questionnaires [International Index of Erectile Function (IIEF), International Prostate Symptom Score]. Sexual function was further assessed by the use of pharmaco duplex ultrasonography of the cavernous arterial blood flow and nocturnal penile tumescence and rigidity monitoring (NPTR). All investigations were performed prior to the start of preoperative radiotherapy and 15 months after surgery. Nine patients (mean age 60 years) participated. Erectile function was maintained in 71% and ejaculation function in 89%. Compared with pre-operative scores on the IIEF, a significant deterioration in intercourse satisfaction was seen following radiotherapy and LTME (7.9 vs 10.3, p = 0.042), but overall satisfaction remained unchanged (8.0 vs 7.0, p = 0.246). NPTR parameters (duration of erectile episodes, duration of tip rigidity > or =60%) decreased following radiotherapy and LTME. Patients reported a deterioration in micturition frequency (2.0 vs 1.0, p = 0.034) and quality of life due to urinary symptoms (8.0 vs 1.8, p = 0.018). Based on these first preliminary findings, data suggest that 15 months after short-term radiotherapy and LTME in men with rectal cancer, objectively assessed sexual dysfunction was considerable, but overall sexual satisfaction had not changed.

    Full Text Available The purpose of the study is to evaluate the relationship between NIH-CPSI and IIEF-5 in Chinese men with CP/CPPS. A large cross-sectional and multicenter survey was conducted from July 2012 to January 2014. Men were recruited from urology clinics which were located at the five cities in China. All men participated in the survey by completing a verbal questionnaire (consisted of sociodemographics, past medical history, sexual history, and self-estimated scales. The results showed that 1,280 men completed the survey. Based on the CP/CPPS definition, a total of 801 men were diagnosed as having CP/CPPS. Men with CP/CPPS reported higher scores of NIH-CPSI and lower scores of IIEF-5 than men without CP/CPPS. NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. The total scores of NIH-CPSI were significantly more strongly correlated with question 5 than other questions of IIEF-5. The total scores of IIEF-5 were significantly more strongly correlated with pain symptoms scores of NIH-CPSI. Strongest correlation was found between QoL impact and question 5 of IIEF-5. The findings suggested that NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. Strongest correlation was found between QoL impact and question 5 of IIEF-5.

    To report the results from a prospective multicentric study of patients with Peyronie's disease (PD) treated with the 'sliding' technique (ST). From June 2010 to January 2014, 28 consecutive patients affected by stable PD with severe penile shortening and end-stage erectile dysfunction (ED) were enrolled in three European PD tertiary referral centres. The validated International Index of Erectile Function (IIEF) questionnaire, the Sexual Encounter Profile (SEP) Questions 2 and 3, and the Peyronie's disease questionnaire (PDQ) were completed preoperatively by all patients. At the follow-up visits (at 3, 6 and 12 months), the IIEF, the SEP Questions 2 and 3, the PDQ, and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) were completed. The outcome analysis was focused on penile length restoration, and intra- and postoperative complications classified according the Clavien-Dindo Classification. The mean (range) follow-up was 37 (9-60) months. A malleable penile prosthesis (PP) was implanted in seven patients, while an inflatable three-pieces PP was placed in the remainder. In the case of inflatable PP implantation, porcine small intestinal submucosa and acellular porcine dermal matrix were used to cover the tunical defects. While in patients undergoing malleable PP implantation, collagen-fibrin sponge was used. The mean operative time was 145 min in the inflatable PP group and 115 min in the malleable PP group. There were no intraoperative complications. Postoperative complications included profuse bleeding requiring a blood transfusion in one patient (3.5%) on anticoagulation therapy for a mechanical heart valve (Grade II) and PP infection requiring the removal of the device (7%) (Grade III). There were no late recurrences of the shaft deformation. The postoperative functional data showed a progressive improvement in the score of all questionnaires, peaking at 12 months postoperatively. The mean (range) penile lengthening was 3.2 (2.5-4) cm and no

    To evaluate the safety and efficacy of sildenafil citrate for treating erectile dysfunction (ED) in patients with combat-related post-traumatic stress disorder (PTSD). In all, 266 combat-exposed war veterans with ED (aged 37-59 years) were recruited. They met the Diagnostic and Statistical Manual of Mental Disorders-IV criteria for PTSD according to the Structured Clinical Interview for Patients, Investigator Version. The patients were also evaluated with the Clinician-Administered PTSD Scale, both to establish the diagnosis of PTSD and to measure symptom severity. Only patients with psychogenic ED were included in the study. Patients with comorbid conditions (diabetes mellitus, hypercholesterolaemia, hypertension, Peyronie's disease) and smokers of more than five cigarettes daily were excluded. The patients were randomly divided into a group of 133 who received 100 mg of on-demand sildenafil 0.75-2 h before sexual stimulation, and 133 who received placebo. Patients were asked to use > or =16 doses or attempts at home. The efficacy of the treatments was assessed every four attempts during treatment, and at the end of the study, using responses to the 15-question International Index of Erectile Function (IIEF), Sexual Encounter Profile diary questions 2 and 3, Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire, patients' event logs of sexual activity, and a Global Assessment Question about erections. Sildenafil did not produce significantly and substantially greater improvement than placebo in each of the primary and secondary outcome measures (P = 0.08). A normal EF domain score (> or =26) at endpoint was reported by 13 (9.8%), and 11 (8.3%) of patients on the sildenafil and placebo regimens, respectively (P = 0.09). Patients treated with sildenafil had no statistically significantly greater improvement in the five sexual function domains of the IIEF questionnaire than those treated with placebo (P = 0.08).

  18. Stress affects a gastrin-releasing peptide system in the spinal cord that mediates sexual function: implications for psychogenic erectile dysfunction.

    Directory of Open Access Journals (Sweden)

    Hirotaka Sakamoto

    Full Text Available Many men suffering from stress, including post-traumatic stress disorder (PTSD, report sexual dysfunction, which is traditionally treated via psychological counseling. Recently, we identified a gastrin-releasing peptide (GRP system in the lumbar spinal cord that is a primary mediator for male reproductive functions.To ask whether an acute severe stress could alter the male specific GRP system, we used a single-prolonged stress (SPS, a putative rat model for PTSD in the present study. Exposure of SPS to male rats decreases both the local content and axonal distribution of GRP in the lower lumbar spinal cord and results in an attenuation of penile reflexes in vivo. Remarkably, pharmacological stimulation of GRP receptors restores penile reflexes in SPS-exposed males, and induces spontaneous ejaculation in a dose-dependent manner. Furthermore, although the level of plasma testosterone is normal 7 days after SPS exposure, we found a significant decrease in the expression of androgen receptor protein in this spinal center.We conclude that the spinal GRP system appears to be a stress-vulnerable center for male reproductive functions, which may provide new insight into a clinical target for the treatment of erectile dysfunction triggered by stress and psychiatric disorders.

    Full Text Available Background. One of the most frequent complications of diabetes in men is erectile dysfunction. Phosphodiesterase-5 inhibitors (IPDE-5: sildenafil, vardenafil and tadalafil are the drugs of choice for the treatment of erectile dysfunction. Objective. To study the effectiveness and safety of treatment of erectile dysfunction with inhibitor of phosphodiesterase 5 in type 2 diabetic men. Material and methods. The study involved 89 men aged 39–69 years old. Рatients with type 2 diabetes mellitus and erectile dysfunction with diabetes duration of 1–12 years were examined in a state of diabetes mellitus compensation (average glycated hemoglobin 7.3 ± 1.1 %. Sildenafil 100 mg on demand before coitus during 12 weeks led to the significant growth rate of domain of «Erectile function» on 10.54 score. Sildenafil was effective in 76.2 % of patients. Increment of such parameter as erectile function during tadalafil treatment was 9.81 scores. Efficacy of tadalafil was 73.1 %. Application of vardenafil led to the improvement of erectile function to an average of 25.22 ± 1.80 scores. Efficacy of vardenafil in our patients was 76.2 %. Conclusions. The study confirmed the high efficiency of three IPDE-5 as the first-line drugs for the treatment of erectile dysfunction in men with diabetes. All three drugs were used in maximum doses, as lower doses are not always effective enough. All patients with reduced blood levels of total testosterone should receive replacement therapy to achieve levels of testosterone within the normal hormone fluctuations. Further study of the effects IPDE-5 in type 2 diabetic men are necessary to improve their effectiveness.

    Although increasing evidences emphasize the importance of early cardiovascular evaluation in men with erectile dysfunction (ED) of unexplained aetiology, impaired masturbation-induced erections in young men are usually overlooked and habitually presumed to be psychological origin. To evaluate the young men presenting weaker masturbatory erection with no sexual intercourse (WME-NS) and verify if this cohort have early cardiovascular risks associated with ED. Male subjects aged 18-40 years with WME-NS were screened by analyzing detailed sexual intercourse and masturbatory history. The age-matched ED and non-ED population were identified by using International Index of Erectile Function-5 (IIEF-5). All subjects with acute and/or chronic diseases (including diagnosed hypertension and diabetes) and long-term pharmacotherapy were excluded. Nocturnal penile tumescence and rigidity (NPTR), systemic vascular parameters and biochemical indicators related to metabolism were assessed. Comparison analysis and logistic regression analysis were conducted among WME-NS, ED and non-ED population. In total, 78 WME-NS cases (mean 28.99 ± 5.92 years), 179 ED cases (mean 30.69 ± 5.21 years) and 43 non-ED cases (mean 28.65 ± 4.30 years) were screened for analysis. Compared with non-ED group, WME-NS group had higher prevalence of early ED risk factors including endothelial dysfunction, insulin resistance, high level of glycosylated serum protein and abnormal NPTR. Multivariable-adjusted logistic regression analysis showed endothelia dysfunction (odds ratio: 8.83 vs. 17.11, both P benefits by targeting these formulated strategies. © 2014 International Society for Sexual Medicine.

    Recent studies have shown that atherosclerosis is associated with erectile dysfunction and the serum bilirubin level. In this study, the serum total bilirubin levels of patients with erectile dysfunction were measured to investigate the relationship between the levels of erectile dysfunction and total bilirubin. A total of 94 patients with erectile dysfunction were divided into three groups; severe erectile dysfunction (33 patients), moderate erectile dysfunction (31 patients), and mild erectile dysfunction (30 patients). In addition, a control group was formed with 31 healthy men. The International Index of Erectile Function-5 Questionnaire was used to measure the quality of erection in all the groups. The body mass index was calculated for all the participants. The serum glucose, low-density lipoprotein and high-density lipoprotein, cholesterol, triglyceride, total bilirubin, and total testosterone levels were also determined. No statistically significant difference was observed between the groups in terms of the mean age, hypertension, smoking status, alcohol use, cardiovascular diseases, hepatobiliary disease, diabetes mellitus, and levels of total testosterone, low-density lipoprotein-cholesterol, and triglyceride. However, high-density lipoprotein, body mass index, and total bilirubin were significantly lower compared to the control group (p < 0.001). The serum total bilirubin level was found to be 0.41 ± 0.21 ng/dL in the severe erectile dysfunction, 0.43 ± 0.19 ng/dL in the moderate erectile dysfunction, and 0.48 ± 0.11 ng/dL in the mild erectile dysfunction groups (p < 0.001). Considering the significant differences between the erectile dysfunction and control groups in terms of serum total bilirubin levels, a low level of bilirubin may have a role in the etiology of erectile dysfunction.

    Full Text Available Whether sexual function is affected by circumcision is a subject of considerable debate among advocate and opponent opinions. We analyzed the sexual function of young men, and the differences between those who were uncircumcised and circumcised, in Taiwan. A total of 506 patients who received circumcision between January 2009 and March 2011 at the urology department in our center were enrolled. Before circumcision, the patients' sexual performances were evaluated using the International Index of Erectile Function-5 (IIEF-5, and the Brief Male Sexual Function Inventory (BMSFI questionnaires. They were evaluated using the questionnaires again, after a postoperative interval of 90 days. Furthermore, intravaginal ejaculation latency times (IELT of the patients were also measured. The IELT and scores in five main domains of the BMSFI, and IIEF, before and after circumcision, were analyzed. A total of 442 patients were available for follow up. The mean age was 25.14 ± 4.46 years (range = 19–35 years. The differences in the BMSFI scores were statistically significant (p < 0.001, especially in increasing sex drive after circumcision (p < 0.001. The IIEF-5 score showed no statistically difference before and after circumcision (p = 0.141. However, after the circumcision, the participants had more erection confidence (p < 0.001, more difficulty in maintaining erections in completing intercourse (p = 0.01, and showed lower IELT scores (p = 0.06. The sexual performance, especially with regards to sex drive and mental erection confidence, seemed to have improved among the patients after circumcision. Our findings may help urologists to better counsel young men receiving circumcisions.

    The radical surgical option we propose for Peyronie's disease consists in removing the sclero-hyalinotic focus of disease and replacing it by an autologous dermal graft taken from the upper outer thigh area. Between 1981 and 1991, we operated 335 patients with IPP, 152 of whom underwent plaque excision and dermal graft. All could be assessed at two-year follow-up. Two main complications were observed: mild penile flexure due to scar retraction of the graft (35% of cases), and partial erectile deficit with decreased corporal rigidity (17% of cases). The degree of the graft retraction is linked to the individual's histologic response. A mild deviation of the penis can occur some months after surgery and is not a relapse flexure due to disease progression (as it should have evolutive characteristics) but is mere scar retraction and will spontaneously regress. As the patient will date the onset of a postoperative erectile deficit from the time of the operation, it is advisable to assess preoperatively the erectile ability of all patients. Furthermore, an impaired erectile response could result from hypoaesthesia of the glans, post-surgical stress, and fibrosis of the erectile tissue. A retrospective assessment of radical surgery cases involving plaque excision and dermal graft lead us to propose this option where precise indications apply, providing the presence of other alterations of the erectile function are pre-operatively assessed.

    Collagenase Clostridium histolyticum (CCH; Xiapex) injections represent the only licensed medical treatment for Peyronie's disease (PD). To evaluate the efficacy and safety of CCH injections in men with stable PD, using a modified treatment protocol and to assess partners' bother improvement in a large cohort of White-European sexually active heterosexual men treated in a single tertiary-referral center. All the 135 patients enrolled underwent a thorough assessment, which included history taking, physical examination, and pharmacologically induced artificial erection test (intra-cavernous injection) to assess the degree of penile curvature (PC) at baseline and after the completion of the treatment. Patients with calcified plaque and/or ventral curvature were excluded. All patients underwent a modified treatment protocol, which consisted of 3 intra-lesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum curvature. After each injection, patients were instructed to follow a strict routine involving daily penile stretching in the intervals between injections. International Index of Erectile Function (IIEF)-15, Global Assessment of PD, PD questionnaires (PDQ), and Female Sexual Function Index (FSFI) questionnaire were performed at baseline and at the end of treatment. Overall, 135 patients completed the study protocol. Before treatment, 18 (13.33%) partners showed a degree of sexual dysfunction. Baseline median IIEF-15, FSFI, and PDQ scores were, respectively, 59.0, 35.0, and 23.0. Overall, both IIEF-total and all domains significantly improved after treatment (all P < .01). A PC mean change of 19.07 (P = .00) was measured. At the univariate linear regression analysis, IIEF-15, IIEF-erectile function, IIEF-sexual desire, and IIEF-intercourse satisfaction were positively associated with FSFI (all P ≤ .03); conversely, PDQ-penile pain, PDQ-symptom bother, and post-treament penile curvature (P ≤ .04) were associated with a decreased

    Full Text Available Introduction: OSAS (obstructive sleep apnea syndrome is defined by recurrent episodes of upper airway obstruction during sleep, causing multiple clinical consequences. Literature review suggests that OSAS induces a spectrum of abnormalities in neural, hormonal and vascular regulation that contribute to the development of ED (erectile dysfunction.The aims of this study were to estimate the prevalence of ED in OSAS patients and evaluate its determinants. Methods: 62 patients from Hospital S. João Sleep Laboratory with newly diagnosed OSAS were included in the study and answered the IIEF-5 (international index erectile function 5 item version questionnaire. Results: The prevalence of ED in OSAS patients was 64.4%. Age and diabetes constituted themselves as independent risk factors for more severe degrees of ED: OR = 1.226 (95% CI: 1.062–1.415 and OR = 31.205 (95% CI: 1.222–796.557, respectively.

    In this study, the prevalence of erectile dysfunction (ED) and serum sexual hormone levels were evaluated in men with obstructive sleep apnea (OSA). In these patients, the efficacy of continuous positive airway pressure (CPAP) was determined. The 207 men (mean age 44.0 ± 11.1 years) enrolled in the study were stratified within four groups based on their apnea-hypopnea index score: simple snoring (n = 32), mild OSA (n = 29), moderate OSA (n = 38), and severe OSA (n = 108). The International Index of Erectile Dysfunction-5 (IIEF-5) score was obtained from each patient, and blood samples for the analysis of sexual hormones (prolactin, luteotropin, follicle-stimulating hormone, estradiol, progestin, and testosterone) were drawn in the morning after polysomnography. The IIEF-5 test and serum sexual hormone measurements were repeated after 3 months of CPAP treatment in 53 men with severe OSA. The prevalence of ED was 60.6 % in OSA patients overall and 72.2 % in those with severe OSA. Compared with the simple snoring group, patients with severe OSA had significantly lower testosterone levels (14.06 ± 5.62 vs. 17.02 ± 4.68, p = .018) and lower IIEF-5 scores (16.33 ± 6.50 vs. 24.09 ± 1.94, p = .001). The differences in the other sexual hormones between groups were not significant. After 3 months of CPAP treatment, there were no significant changes in sexual hormone levels, but the IIEF-5 score had improved significantly (18.21 ± 4.05 vs. 19.21 ± 3.86, p = .001). Severe OSA patients have low testosterone concentration and high ED prevalence. IIEF-5 scores increased significantly after CPAP treatment, but there was no effect on serum testosterone levels.

  11. Pharmacotherapy of erectile dysfunction: Current standards

    Full Text Available Pharmacotherapy is currently the therapeutic option of choice for erectile dysfunction. Comprising mainly intracavernosal injection therapy using alprostadil or alprostadil combined with phentolamine and/or papaverine and oral phosphodiesterase-5 inhibitors, it is safe and effective if appropriately prescribed and administered. The medications in current use produce satisfactory erectile responses by enhancing cavernosal vasodilatation mainly through their ability to promote relaxation of the smooth muscle cells in the corpora cavernosa involving the synthesis and activity of nitric oxide via the cyclic guanosine monophosphate and cyclic adenosine monophosphate biochemical pathways. The main side-effects and complications of intracavernosal injections are postinjection pain, prolonged erections, priapism and penile fibrosis. There may be a variety of side-effects with phosphodiesterase-5 inhibition but these are usually inconsequential. Recent serious ill health and the need for ongoing long-acting nitrate therapy or frequent use of short-acting nitrates for angina are absolute contraindications to the use of phosphodiesterase-5 inhibitors. Caution has to be exercised in prescribing phosphodiesterase-5 inhibitors for patients with impaired renal or hepatic functions or receiving multi-drug therapy for any systemic disease. All patients presenting with erectile dysfunction should be investigated and treated for cardiovascular risk factors. They should also be counseled regarding lifestyle factors particularly healthy balanced diet, regular physical exercise and inappropriate social habits.

    Erectile dysfunction is a highly publicized and prevalent condition with marked adverse effects on men's social, emotional, and quality of life. Although several instruments have emerged for assessing erectile dysfunction and its impact on men's quality of life, none of the existing instruments provide a specific assessment of men's erectile performance anxiety. This article reports on the development and psychometric evaluation of the Erectile Performance Anxiety Index (EPAI)--a 10-item self-report scale designed to fill an important gap in the assessment of male erectile dysfunction. A total of 207 men ranging in age from 18 to 79 took part in the study. All subjects completed an online battery consisting of the EPAI, along with measures of related sexual functioning, social anxiety, state anxiety, and depressive symptoms. A small subset of study participants (N = 42) completed the EPAI a second time for determining test-retest reliability. Test-retest reliability was determined by Pearson's product-moment correlations. Internal reliability was assessed using Cronbach's alpha. Factor validity was evaluated by a maximum likelihood factor analysis with oblique rotation. Convergent and discriminant validity was assessed by comparing the strength of association between the EPAI and measures varying in their hypothesized shared variance with the construct of erectile performance anxiety. The EPAI demonstrated excellent internal consistency, with Cronbach's alpha = 0.93 and excellent test-retest reliability (r = 0.85) over an average period of 3.5 weeks. Results of an exploratory factor analysis revealed a one-factor solution that accounted for 63% of the total variance. Preliminary evidence supports the convergent and discriminant validity of the EPAI. Results support the use of the EPAI as a reliable, valid, and efficient instrument for the assessment of erectile performance anxiety. Potential research and clinical applications are discussed. © 2013 International

    Full Text Available Objectives: The aim of this study was to assess the prevalence of patients with Erectile Dysfunction (ED receiving psychotropic drugs, the impact of these drugs on hormonal profile, and the efficacy of PDE5-i in these patients. Materials and methods: We recruited 1872 patients referring for ED to our Andrology Unit. Assessment included serum testosterone, gonadotropins, TSH, prolactin, and PSA, and the IIEF-5 questionnaire for ED diagnosis. Inclusion criteria were age 21-75 years and IIEF-5 total score ≤ 21; exclusion criteria included hypogonadism, diabetes mellitus, previous prostatectomy, other medication intake, and ED diagnosis prior to psychotropic drug treatment. Efficacy was rated with the IIEF-5 (remission: total score ≥ 22. Results: The prevalence of ED patients treated with psychotropic drugs since ≥ 3 months was 9.5% (178/1872, subdivided according to the drugs used into: Group A, 16 patients treated with atypical antipsychotics (9.0%; Group B, 55 patients with benzodiazepines (30.9%; Group C, 33 patients with antidepressant drugs (18.5%; and Group D, 74 patients with multiple psychotropic drugs (41.6%. Patients in Group A were significantly younger than other groups (p < 0.05. The hormonal profile presented only higher prolactin level in patients treated with antipsychotics, alone or in combination (p < 0.05. Overall, 146 patients received PDE5-i. Remission rate, after three months of treatment, was significantly higher in Group B compared to C and D groups (p < 0.05. Conclusions: A substantial portion of patients receiving psychotropic drugs show ED. Sexual performance in these patients benefits from PDE5-i. Age, effects of psychiatric disorders, psychotropic drugs, and PDE5-i treatment modality accounted for variability of response in this sample.

    Phosphodiesterase type 5 inhibitors and α-adrenergic blocking agents (α-blockers) are widely used for the treatment of erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). To assess the efficacy and safety of fixed-dose combinations (FDCs) of tamsulosin and tadalafil compared with tadalafil monotherapy in patients with comorbid BPH-associated LUTS and ED. A randomized, double-blinded, active-controlled trial was conducted of 510 men with BPH-associated LUTS and ED. Patients were treated with FDCs of tamsulosin 0.4 mg plus tadalafil 5 mg (FDC 0.4/5 mg), tamsulosin 0.2 mg plus tadalafil 5 mg (FDC 0.2/5 mg), or tadalafil 5 mg for a 12-week treatment period. For a subsequent 12-week extension period, the patients were administered FDC 0.4/5 mg. The primary outcomes were changes from baseline in total International Prostate Symptom Score (IPSS) and International Index of Erectile Function erectile function domain (IIEF-EF) score at week 12 to prove superiority and non-inferiority of FDCs compared with tadalafil 5 mg. The safety assessments were adverse reactions, laboratory test results, and vital signs at week 24. The mean changes in total IPSS and IIEF-EF scores were -9.46 and 9.17 for FDC 0.4/5 mg and -8.14 and 9.49 for tadalafil 5 mg, respectively, which indicated superiority in LUTS improvement (P = .0320) and non-inferiority in ED treatment with FDC 0.4/5 mg compared with tadalafil 5 mg. However, the results from FDC 0.2/5 mg failed to demonstrate superiority in LUTS improvement. No clinically significant adverse events regarding the investigational products were observed during the 24-week period. The FDC 0.4/5 mg is the first combined formulation of an α-blocker and a phosphodiesterase type 5 inhibitor that offers benefits in patient compliance and as add-on therapy in patients with comorbid BPH-associated LUTS and ED. The study clearly demonstrated the advantage of FDC 0.4/5 mg. The main

    Erectile dysfunction (ED) is one of many consequences of spinal trauma. Its extent is influenced by several factors, depending mainly on the height of spinal injuries as well as the premorbid state. The incidence of spinal cord injuries in the Czech Republic and around the world has a slightly upward trend. Epidemiological statistics include mostly young people for whom sexual activity has a reproductive function. Disorders in the intimate area seriously and significantly reduce the quality of life. The article presents current theoretical knowledge of erectile dysfunction, according to epidemiological data on spinal cord injuries in the Czech Republic, and an overview of up-to-date therapeutic modalities for erectile dysfunction in men after spinal trauma.

    Although many studies about penile prosthesis implantation (PPI) have been published so far, only a small amount of them take into account patients and partners outcome in terms of satisfaction and erotic function. The aim of this study is to explore the value of psycosexual counselling in and the sexual and erotic function of penile prosthesis recipients. Thirty patients and their partners were randomised into two groups. In arm A (case group) patients and their partners underwent a multistep psychosexual counselling before and after surgery. In arm B (control group) surgery was performed without the specific psychosexual counselling scheme. Specific questionnaires (International Index of Erectile Function (IIEF) and the Sexual Daydreaming Scale (SDS)) were administered before surgery and 12 months afterwards. Twenty-four months postoperatively patients were asked to complete the Global Assessment Questions (GAQ) and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), while their partners were asked to answer to the EDITS partner's section. Between January 2009 and October 2011, we enrolled 30 patients undergoing PPI in our institution (15 in each arm). Twenty-four months postoperative follow-up is available for all of them. No significant differences between the two groups in terms of baseline questionnaires scores were observed. Mean IIEF score was significantly higher in case group (arm A 68.3, arm B 53.4, P-valueerotic function according to SDS was significantly higher in the study group for both patients and their partners. Improvement in satisfaction rates were confirmed at 24 months, with statistically significant scores for EDITS in arm A patients and partners as compared with arm B. PPI with a pre- and postoperative psychosexual counselling scheme resulted in better postoperative sexual activity and erotic function for both patients and partners than PPI alone.

    Sexual limitations play an important role in the quality of life of patients with chronic diseases. Very limited information is available on the impact of asthma on the sexual functioning of these individuals. Cross-sectional, observational, multicenter study. Asthma patients and healthy individuals were recruited. All subjects participated in an interview in which demographic and clinical data were recorded, and completed the Goldberg Anxiety-Depression Scale (GADS) to evaluate the presence of concomitant psychiatric disease. Men also completed the International Index of Erectile Function (IIEF), and women, the Female Sexual Function Index (FSFI). A total of 276cases were included, comprising 172asthma patients (63 men and 109 women) with a mean age of 42 (±14) years, and 104 controls (52men and 51women) with a mean age of 39 (±12) years. Time since onset of asthma was 15 years and severity distribution was: 6.4% intermittent, 17.9% mild persistent, 47.4% moderate, and 28.2% severe. Disease was considered controlled in 57.7%, partially controlled in 28.2%, and uncontrolled in 14.1%. Women with asthma had greater sexual limitations than women in the control group, with a total FSFI score of 22.1 (±9) compared to 26.5 (±6.8), respectively (P<.005). Men with asthma had significantly more severe erectile dysfunction with a total IIEF score of 59.5 (±12.5) compared to 64.3 (±8.2) in male controls (P<.05). An association was also observed between sexual problems and poorer asthma control. Asthma is associated with a poorer sexual quality of life among patients. These results should arouse the interest of healthcare professionals in detecting and alleviating possible sexual limitations among their asthma patients in routine clinical practice.

    Lifestyle and nutrition have been increasingly recognized as central factors influencing vascular nitric oxide (NO) production and erectile function. This review underscores the importance of NO as the principal mediator influencing cardiovascular health and erectile function. Erectile dysfunction (ED) is associated with smoking, excessive alcohol intake, physical inactivity, abdominal obesity, diabetes, hypertension, and decreased antioxidant defenses, all of which reduce NO production. Better lifestyle choices; physical exercise; improved nutrition and weight control; adequate intake of or supplementation with omega-3 fatty acids, antioxidants, calcium, and folic acid; and replacement of any testosterone deficiency will all improve vascular and erectile function and the response to phosphodiesterase-5 inhibitors, which also increase vascular NO production. More frequent penile-specific exercise improves local endothelial NO production. Excessive intake of vitamin E, calcium, l-arginine, or l-citrulline may impart significant cardiovascular risks. Interventions discussed also lower blood pressure or prevent hypertension. Certain angiotensin II receptor blockers improve erectile function and reduce oxidative stress. In men aged acids may be particularly crucial for these men at greatest risk for sudden death. In conclusion, by better understanding the complex factors influencing erectile and overall vascular health, physicians can help their patients prevent vascular disease and improve erectile function, which provides more immediate motivation for men to improve their lifestyle habits and cardiovascular health.

    The first double-blind, placebo controlled trial in the United States of the Self-Esteem And Relationship questionnaire revealed that treatment with sildenafil citrate improves erectile function and measures of quality of life in men with erectile dysfunction. We investigated long-term improvement, and correlations between improved erectile function and confidence, self-esteem and sexual relationship satisfaction in men with erectile dysfunction. This was a 36-week open label extension of the double-blind, placebo controlled trial. The blind was not broken. Patients were 18 years or older with clinically diagnosed erectile dysfunction. Erectile function was assessed using the International Index of Erectile Function. Self-esteem, confidence and relationship satisfaction were assessed using the Self-Esteem And Relationship questionnaire. Correlations were determined using Pearson's product moment coefficients. A total of 204 participants were enrolled in the open label extension, including 108 on placebo and 96 on sildenafil. In men who received placebo in the double-blind, placebo controlled phase mean erectile function scores and self-esteem, confidence and relationship satisfaction scores were increased significantly at week 36 of the open label extension (p self-esteem, confidence and relationship satisfaction were strong and positive (p self-esteem, confidence and relationship satisfaction. Following an initial 12 weeks of double-blind, placebo controlled sildenafil therapy for erectile dysfunction improvements were sustained an additional 9 months. Positive correlations between erectile function, and self-esteem, confidence and relationship satisfaction suggest that improved erectile quality can improve long-term psychosocial quality of life.

  1. Male erectile dysfunction: integrating psychopharmacology and psychotherapy.

    2013-01-01

    Erectile dysfunction (ED), defined as the inability to achieve or maintain an erection sufficient for satisfactory sexual performance, is the most common sexual problem in men. ED arises when there is disruption of the complex interplay between vascular, neurologic, hormonal and psychologic factors necessary for normal erectile function. It may have a significant effect on quality of life and portend undetected cardiovascular disease. Risk factors for development of ED include advancing age, tobacco use, a history of pelvic irradiation or surgery and antipsychotic use (Table 1) [1]. Treatment guidelines continue to evolve for optimal management of ED. In this article, we review diagnostic and treatment strategies for ED relevant to psychiatrists. We present an integrative approach to the treatment of ED based on a review of the urologic and psychiatric literature. ED is multifactorial in origin and responsive to a variety of therapeutic interventions, including psychopharmacology and psychotherapy in which cognitive underpinnings of poor sexual performance, including diminished self-esteem, lack of confidence and perceived failures in the male role, are examined. Psychiatrists can readily perform a basic workup for ED as they integrate both a medical and therapeutic model when confronted with such patients. Copyright © 2013 Elsevier Inc. All rights reserved.

  2. Modifying Risk Factors in the Management of Erectile Dysfunction: A Review

    Directory of Open Access Journals (Sweden)

    Kenneth J DeLay

    2016-08-01

    Full Text Available Erectile dysfunction (ED is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM, tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient’s overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process.

    Full Text Available Alan Saleh, Hamid Abboudi, MB Ghazal-Aswad, Erik K Mayer, Justin A Vale Division of Surgery and Cancer, Imperial College Healthcare NHS Trust, St Mary's Hospital, London, UK Abstract: Radical prostatectomy is a commonly performed procedure for the treatment of localized prostate cancer. One of the long-term complications is erectile dysfunction. There is little consensus on the optimal management; however, it is agreed that treatment must be prompt to prevent fibrosis and increase oxygenation of penile tissue. It is vital that patient expectations are discussed, a realistic time frame of treatment provided, and treatment started as close to the prostatectomy as possible. Current treatment regimens rely on phosphodiesterase 5 inhibitors as a first-line therapy, with vacuum erection devices and intraurethral suppositories of alprostadil as possible treatment combination options. With nonresponders to these therapies, intracavernosal injections are resorted to. As a final measure, patients undergo the highly invasive penile prosthesis implantation. There is no uniform, objective treatment program for erectile dysfunction post-radical prostatectomy. Management plans are based on poorly conducted and often underpowered studies in combination with physician and patient preferences. They involve the aforementioned drugs and treatment methods in different sequences and doses. Prospective treatments include dietary supplements and gene therapy, which have shown promise with there proposed mechanisms of improving erectile function but are yet to be applied successfully in human patients.

    Penile erection is a complex phenomenon that includes coordinated intraaction of the nervous, arterial, venous, and sinusoidal systems. A defect in any of these systems may result in erectile dysfunction. Erectile dysfunction is defined as the consistent inability to generate or maintain an erection of sufficient rigidity for sexual intercourse. Although the introduction of sildenafil citrate made the information from imaging studies less critical in the management of the patients with erectile dysfunction, still the imaging studies such as Doppler US, penile arteriography, and cavemosonetry/cavemosography remain the major modalities in the evaluation of erectile dysfunction.

    Today cycling is considered a useful form of exercise for reducing cardiovascular risk, but it may also represent a risk factor for erectile dysfunction and perineal-genital paresthesia. These disorders are attributed to the local reduction of oxygen in the perineal-genital area, secondary to the perineal compression. Numerous studies have been carried out measuring the penile oxygen pressure or penile blood flow by echo-colour-Doppler: a reduced inflow of blood and oxygen to the cavernous tissue was demonstrated. The attention of the specialist is therefore concentrated on the compression of the perineum on the bicycle saddle and how to reduce this through the position of the cyclist on the bicycle (i.e. height and tilt of the saddle), the different shapes of saddle available (i.e. noseless, grooved, wide, etc.) and the padding materials of the saddle. In order to reduce perineal compression, the posterior part of the saddle should be as wide as the distance between the two ischiatic tuberosities. In addition, the saddle should be studied on the basis of the biotype of the cyclist: ectomorphic, mesomorphic or endomorphic. However, in the genesis of the erectile dysfunction of the cyclist, apart from the above-mentioned factors, an "individual predisposition to developing erectile dysfunction" linked to the perineal-genital anatomy (i.e. type of insertion of the perineum into the root of the penis, number of layers of the tunica albuginea of the corpus cavernosum) cannot be excluded.

    Erectile dysfunction is a major complication of radical prostatectomy, commonly associated with penile neuropathy. In animal models of peripheral nerve injury, glial growth factor-2 (GGF2), a member of the neuregulin family of growth factors, has neuroprotective and neurorestorative properties, but this potential has not been established after cavernous nerve (CN) injury. The effectiveness of GGF2 in preserving axonal integrity and recovering erectile function in a rat model of radical prostatectomy-associated CN injury. Adult male Sprague-Dawley rats underwent bilateral CN crush injury (BCNI) or sham surgery. Rats were administered GGF2 (0.5, 5, or 15 mg/kg) or vehicle subcutaneously 24 hour pre and 24-hour post-BCNI, and once weekly for 5 weeks. Erectile function was assessed in response to electrical stimulation of the CN. CN survival was assessed by fluorogold retrograde axonal tracing in major pelvic ganglia (MPG). Unmyelinated axons in the CNs were quantitated by electron microscopy. Erectile function recovery, CN survival, and unmyelinated CN axon preservation in response to GGF2 treatment following BCNI. Erectile function was decreased (P cells in the MPG was reduced (P Schwann cells in the BCNI group was higher (P Schwann cell compared with the BCNI group. GGF2 promotes erectile function recovery following CN injury in conjunction with preserving unmyelinated CN fibers. Our findings suggest the clinical opportunity to develop GGF2 as a neuroprotective therapy for radical prostatectomy. © 2015 International Society for Sexual Medicine.

    Full Text Available Today the problem of better life quality of patients with end stage renal disease and after renal transplantation and their sexual adaptation is considered to be more impotent. The clinical part of the investigation is the obser- vation of 205 patients – men with terminal stage renal disease. Erectile dysfunction is represented in 91,4% (64 of patients getting haemodialysis, 92,3% (24 of patients getting peritoneal dialysis, 61,5% (67 of patients after renal transplantation. According to International Index of Erectile Function the mean score of erectile function is 16,7 ± 5,2 in haemodialysis patients, 19,46 ± 3,6 in peritoneal dialysis patients, 21,9 ± 5,6 in patients after renal transplantation. The analysis revealed great prevalence of erectile dysfunction and interest in improvement among the patients with end stage renal disease and after renal transplantation.

    ED and LUTS affect a high proportion of male population. Although Hispanics are suspected to have a higher risk of experiencing LUTS, detailed information on its frequency and association with ED in this population is scarce. To determine the frequency of LUTS and ED, and its correlation in Mexican males. A cross-sectional analytical survey was answered by 1041 men. It included the International Prostate Symptom Score and the quality of life question (IPSS/QoL); International Index of Erectile Function (IIEF-5); the short form of the International Consultation of Incontinence Questionnaire (ICIQ-SF); and demographic data. For the analysis, we divided our population into 2 groups (18-39 and 40 and older), and then an exploratory correlation analysis was performed to search for significant differences among IPSS severity groups, and finally a multivariate regression model was applied. Mean age was 48.6 ± 14.5 years. One hundred twenty-three individuals (11.8 %) were asymptomatic, and 611 (58.7 %) had mild, 226 (21.7 %) had moderate, and 81 (7.8 %) had severe IPSS score. The most common symptoms were nocturia (72.4 %), increased urinary frequency (58.3 %), and slow urinary stream (42.6 %). Two hundred fifty-eight (24.7 %) complained of incontinence. Of 765 individuals, 484(63.2 %) reported some degree of ED. Severe LUTS, DM, and age were independent risk factors for ED severity. LUTS and ED may represent one of the largest sources of morbidity in our population, and their association was demonstrated. Awareness on these entities should be raised, and further research is required to determine the higher frequency of LUTS and ED in Hispanics.

    To assess persistence/adherence rates of phosphodiesterase type-5 inhibitor (PDE5I) on-demand dosing in Latin American men with erectile dysfunction (ED), and explore patient characteristics and treatment factors that may be predictive for PDE5I persistence and adherence. Men from Brazil, Mexico, and Venezuela with ED who were naïve to PDE5Is were prescribed sildenafil, tadalafil, vardenafil, or lodenafil on-demand dosing and asked to provide information about PDE5I use at baseline and at 1, 3, and 6 months. Patients were persistent if they used ≥1 dose during the 4 week period prior to each evaluation. Patients were adherent if they complied with dosing instructions during most recent dose. Main outcome measures included Persistence and Adherence Questionnaire (PAQ), Partner Relationship Questionnaire (PRQ), Self-Esteem and Relationship (SEAR) Questionnaire, and International Index of Erectile Function (IIEF). Multivariate logistic regression was used to identify factors associated with persistence and adherence. A total of 511 men were enrolled; most had mild to moderate ED (77.1%); 317 patients (62.0%) were prescribed tadalafil, 116 (22.7%) sildenafil, 75 (14.7%) vardenafil, and 3 (0.6%) lodenafil (not further analyzed). A total of 340 patients (66.5%) were 'persistent' at 6 months; 345 (67.5%) were 'adherent'. Persistence and adherence were associated with age, education level, and ED duration. Reasons for non-persistence included medication cost and lack of efficacy. Study limitations included its design, brief observation period, its bias observed toward tadalafil selection; its dependence on patient self-reporting, limited number of factors that were analyzed for persistence/adherence association, its small number of participating patients and Latin American countries, and inherent differences in PDE5I preference and medical practices. Approximately two-thirds of PDE5I-naïve, Latin American men with ED were persistent and adherent after 6 months of

    Erectile dysfunction (ED) is often associated with a wide array of psychiatric symptoms, although few studies systematically address their specific association with ED determinants. The aim of this study is to explore the relationship between ED (as assessed by SIEDY Structured Interview, a 13-item tool which identifies and quantifies the contribution of organic, relational, and intrapsychic domains of ED) and different psychopathological symptoms (as assessed by the Middlesex Hospital Questionnaire, a self-reported test for the screening of mental disorders in a nonpsychiatric setting). A consecutive series of 1,388 (mean age 51 +/- 13 years) male patients with ED was studied. Several hormonal and biochemical parameters were investigated, along with SIEDY Interview and the Middlesex Hospital Questionnaire. Psychiatric symptoms resulted differentially associated with SIEDY domains. Depressive and phobic-anxiety symptoms were associated with the relational domain, somatization with the organic one, while free-floating anxiety, obsessive-compulsive, and phobic symptoms were significantly related with higher intrapsychic SIEDY scores. In addition, relevant depressive symptomatology was associated with hypogonadism, the presence of low frequency of intercourse, hypoactive sexual desire (HSD), and conflictual relationships within the couple and the family. Patients with high free-floating anxiety symptoms were younger, and complained of an unsatisfactory work and a conflictual relationship within family. Conversely, subjects with higher phobic anxious symptoms displayed a more robust relational functioning. Similar results were observed in subjects with obsessive-compulsive symptoms, who also reported a lower prevalence of HSD. Finally, subjects with somatization symptoms showed the worst erectile function. The main value of this study is that it alters various clinicians' belief that many psychiatric symptoms can be found among ED patients. Systematic testing of

    We retrospectively evaluated the clinical outcome of penile prosthesis implantation (PPI) in Chinese patients with severe erectile dysfunction (SED). From July 2000 to December 2011, 224 patients (mean age: 35.9±11.8 years, range: 20–75 years) with SED underwent PPI by experienced surgeon according to standard PPI procedure at our centre. A malleable prosthesis (AMS 650) was implanted in 45 cases (20.1%), and a three-piece inflatable prosthesis (AMS 700 CXM or AMS 700 CXR) was implanted in 179 cases (79.9%). Surgical outcomes, including postoperative complications, clinical efficacy and couple satisfaction, were evaluated over than 6 months postoperatively using medical record abstraction, IIEF-5, quality of life (QoL) scores, and the patient/partner sexual satisfaction score proposed by Bhojwani et al. Of the 224 patients eligible for the study, 201 subjects (89.7%) completed follow-up. All of patients could perform sexual intercourse post PPI with the mean postoperative IIEF-5 and QoL scores were 20.02±2.32 and 5.28±0.76, respectively, which were significantly improved compared with the preoperative scores (6.29±1.5 and 2.13±0.84, Preported by 178 men (88.6%), and overall satisfaction with the PPI surgery was reported by 89.0% of men and 82.5% of partners. Patient satisfaction in the three-piece inflatable prosthesis group was higher than in the malleable prosthesis group (P<0.05). Satisfaction, however, between the types of prostheses, did not differ in the partner survey. PPI is a safe and effective treatment option for Chinese patients with SED and experienced surgeon perform PPI according to standard PPI procedure could reduce the postoperative complications of PPI and could improve patient satisfaction ratio and QoL.

    Erectile dysfunction is a common consequence of external beam radiotherapy (EBRT) for prostate cancer. The addition of neo-adjuvant androgen deprivation (NAD) has an indeterminate additive effect. We examined the long-term effect on erectile function (EF) of two durations (4 months: arm 1 and 8 months: arm 2) of NAD prior to radiation (RT) for patients with localised prostate cancer from the Irish Clinical Oncology Research Group (ICORG 97-01) 4- versus 8-month trial. In this study we aimed to (1) analyse the overall effect on EF of NAD in an EBRT population, (2) compare the probability of retained EF over time in an EBRT population treated with either 4 or 8 months of NAD and (3) identify any variables such as risk group and age which may have an additive detrimental effect. This analysis provides unique long term follow up data.

    Full Text Available Erectile dysfunction (ED is a disorder, which basically can have organic nature, psychological or mixed. ED is not a rarity, and data on its prevalence vary, depending on the areas in which the survey was conducted, followed by a period of research and the definition of the disorder. Most of the men associate ED problem with using drugs, especially cardiac. Even though there is some truth in it, mainly the real causes of ED are not well known even to professionals. Contemporary studies of risk factors for cardiovascular disease, particularly coronary heart disease, have shown the clear link between erectile dysfunction and coronary heart disease, wherein ED first manifests. While, ED precedes the onset of symptoms of coronary heart disease and show to the patient and the physician a clear signal of the direction for conducting diagnostic tests and further treatment in the interest of the health of patients. Endocrine, and neurological disorders, as well as bad habits in addition to the cardiac and kidney disease, lead to ED. It is known also, that the use of cardiac medicines may contribute to ED occurrence. Better knowledge of adverse reactions to medicines, a better understanding of the nature of the disease and the implementation of necessary diagnostic procedures, with a good choice of medication, contribute to solving problems related to ED. If all mentioned do not help, there is the possibility of using new drugs to correct ED.

    Full Text Available Objectives: Hypotestosteronemia has been reported in approximately half of type 2 diabetic men in general. This study aims to assess serum total testosterone levels in type 2 diabetics with erectile dysfunction and to correlate the degree of improvement between sildenafil citrate and testosterone levels. Methods: A cross sectional and prospective comparative interventional study was conducted at the Diabetic Clinic of Assalam Teaching Hospital in Mosul, during the period from January 1, 2009 through to December 31, 2011. The study enrolled 120 type 2 diabetic males with erectile dysfunction who were analyzed with regard to age, duration of diabetes, duration and severity of erectile dysfunction, serum total testosteron levels and the degree of response to sildenafil citrate in terms of testosterone levels. The data were statistically analyzed using the independent two-sample Student t test, χ2 test and Pearson correlation test. A p-value of <0.05 was considered statistically significant. Results: Thirty six percent of type 2 diabetic males with erectile dysfunction were found to have low serum testosterone levels. The hypotestosteronemic and normotestosteronemic subgroups were not significantly different in terms of mean age, duration of diabetes, reduction of libido, and reduction in erectile function. The rate and the degree of improvement of erection by sildenafil in the normo-and-hypotestosteronemic respondents were not significantly different, but the degree of improvement by sildenafil was significantly correlated to testosterone levels among the hypotestosteronemic group. Conclusion: Hypotestosteronemia was found in 36% of type 2 diabetic males with erectile dysfunction. The degree of improvement of erectile dysfunction by sildenafil was directly proportional to the serum testosterone levels among the hypotestosteronemic group.

Both the diseases share common risk factors. Various studies conducted in different parts of the world in recent years reported the evidence linking this relationship as well as improvement in ED with periodontal treatment. Systemic exposure to the periodontal pathogen and periodontal infection-induced systemic inflammation was thought to associate with these conditions.

    2010-04-01

    Recent studies have shown the impact of sexual dysfunctional beliefs, negative cognitive schemas, negative automatic thoughts, and depressed affect on male erectile dysfunction. Despite this fact, there are only few conceptual models that try to integrate these findings, and more importantly, there is a lack of studies that test the validity of those conceptual models. The aim of the present article was to test a cognitive-emotional model for erectile dysfunction. Taking previous research findings into account, we developed a cognitive-emotional model for erectile disorder (ED) and used path analysis to test it. A total of 352 men (303 participants from the general population and 49 participants with a DSM-IV diagnosis of sexual dysfunction) answered a set of questionnaires assessing cognitive and emotional variables. Erectile Function measured by the EF subscale of the International Index of Erectile Function, cognitive schemas measured by the Questionnaire of Cognitive Schema Activation in Sexual Context, sexual beliefs measured by the Sexual Dysfunctional Beliefs Questionnaire, thoughts and emotions measured by the Sexual Modes Questionnaire. The effects of the main proposed direct predictors explained 55% of the erectile function variance (R = 0.74). Most remaining direct effects proposed in the model were also statistically significant. The analysis of the absolute residuals showed that most of the implied correlations were close to the observed zero order correlations, indicated the adjustment of the model to the observed data. These findings support the role played by cognitive and emotional factors on the predisposition and maintenance of male erectile dysfunction and suggest important implications for assessment and treatment of ED.

    The aim of this study was to determine the demographic features of erectile dysfunction patients attending different specialized clinics in Jeddah city, and to identify possible risk factors associated with erectile dysfunction problem. All newly erectile dysfunction patients (n=388) who attended 6 andrology and urology clinics within a period of 3 months were subjected to a modified structural interview questionnaire to collect demographic data and risk factors for erectile dysfunction. The study revealed the following results among erectile dysfunction patients; Saudi patients constituted (81%). The age ranged from 20-86 years with mean age of 43.23+12.56 years, 73% were married with one wife, 23.5% married with two wives, and 8% were single. About one-half (43%) were less than secondary education level. Retired patients constituted (13%) of all patients. Lack of exercise was the most frequent risk factor among 82% of patients, followed by smoking (56%), use of regular medication (44%), diabetes (30%), hypertension (15%), history of pelvic surgery (14%) alcoholism (13%), and drug addict (8%). Erectile dysfunction is a problem of not only old age but also of middle and young age. This might be attributed to the high frequency of some risk factors such as diabetes mellitus, hypertension, smoking, alcohol consumption, and drug addiction. This finding may reflect the necessity for construction of prevention strategies.

    To explore the topological properties of the degree and strength of nodes in the binary and weighted brain white matter networks of the patients with psychogenic erectile dysfunction (pED) and analyze the changes of myelin integrity, number and length of the white matter fibers in the topological space. Diffusion tensor imaging data were obtained from 21 patients with pED and 24 healthy controls matched in sex, age, and years of education and subjected to preprocessing. The whole cerebral cortex was divided into 90 regions, followed by fiber tracking, construction of the binary and weighted white matter networks, and calculation of the node degrees and connectivity strengths in different brain regions. The property values were compared between the two groups using the two-sample t-test, the results were corrected by multiple testing correction, and the correlation of the property values with the erectile function of the patients was subjected to Pearson's correlation analysis. Compared with the healthy controls, the pED patients showed significantly decreased node degree of the left triangular part of inferior frontal gyrus (IFG) (7.54±1.44 vs 5.95±1.28, t = -3.88, corrected P = 0.02), medial orbital part of superior frontal gyrus (SFG) (10.08±3.60 vs 6.29±3.30, t = -3.67, corrected P = 0.02), and amygdala (6.50±2.11 vs 4.29±1.31, t = -4.16, corrected P = 0.01) in the binary networks, as well as the connectivity strength of the left triangular part of IFG (2.50±0.68 vs 1.72±0.50, t = -4.35, corrected P = 0.01), medial orbital part of SFG (3.17±0.97 vs 2.08±1.10, t = -3.53, corrected P = 0.03), and amygdala (1.80±0.69 vs 1.11±0.39, t = -4.03, corrected P = 0.01) in the fractional anisotropy (FA) weighted networks. The node degree of the left amygdala was negatively correlated with the total score (r = -0.47,P = 0.04), second item score (r = -0.46, P = 0.03), and third item score of IIEF-5 (r = -0.45, P = 0.04) in the pED patients.

    In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post-radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

    Case-control study. (i) To describe the prevalence of sexual dysfunction in chronic low back pain (CLBP) patients, (ii) to compare the range of sexual function outcomes between patients with CLBP and healthy controls and (iii) to investigate which factors are associated with sexual function within the cohort of individuals with CLBP. Low back pain (LBP) clinic of Qazvin University of Medical Sciences, Qazvin, Iran. A total of 702 patients with CLBP and 888 healthy controls participated in the study. The Female Sexual Function Index (FSFI), International Index of Erectile Function (IIEF) and Premature Ejaculation Diagnostic Tool (PEDT) were used to evaluate sexual function. In addition, quality of life, anxiety, functional status and pain intensity were assessed in patients. Univariate and multiple linear regression analyses were performed for the identification of factors associated with sexual function. The prevalence of sexual problems in female patients with CLBP was 71.1% (n=177) while the corresponding figure for healthy women was 36.8% (n=161). Erectile dysfunction was present in 59.5% of male patients and in 24.5% of healthy males. Higher sexual function in both male and female patients with CLBP were being younger, lower duration of back pain, lower BMI, higher education level, being unemployed, physically active shorter sick leave, lower level of pain intensity, lower disability, higher family income, lower levels of depressive and anxiety symptoms, and higher psychical functioning and mental functioning. CLBP patients report considerably higher prevalences of sexual problems compared with healthy controls. Sex therapy and sexual management should be added to routine care and treatment of patients with CLBP.

    Full Text Available Daniar Kurmanbekovich Osmonov, Aleksey Aksenov, Andrea Nathaly Guerra Sandoval, Almut Kalz, Klaus Peter Juenemann Department of Urology and Pediatric Urology, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany Introduction: This paper reports treatment of a 76-hour low-flow priapism with a shunting procedure that was first described by Barry in 1976. We were able to observe the preservation of erectile function despite the long period of ischemia. A review of the literature shows that there are few reports of erectile function recovery after a priapism of similar duration. Materials and methods: A 42-year-old patient presented with a 76-hour priapism, probably caused by consumption of alcohol and illegal drugs. A Barry Shunt procedure was performed. The erectile function of the patient was assessed by means of International Index of Erectile Function score over a follow-up period of 30 months. Moreover, we reviewed different surgical options for treatment of priapism in the literature. Results: Partial return of erection without sexual arousal occurred on two occasions during the 10-day hospitalization, but was treated by manipulation of the penis, ie, by milking the tumescence into the shunt. After 3 months, the shunt was still palpable as a subcutaneous swelling. Six months postoperatively, the residual swelling had disappeared. The International Index of Erectile Function score was of 21 without phosphodiesterase type 5 inhibitors after a follow-up of 2.5 years. Conclusion: Barry shunt is an effective alternative surgical option for the treatment of low-flow priapism. In the case of our patient, it was also effective after a 76-hour-lasting priapism. Keywords: low flow priapism, erectile function, cavernovenous shunt, surgical treatment of stuttering priapism

    Oxidative stress and inflammation, which disrupt nitric oxide (NO) production directly or by causing resistance to insulin, are central determinants of vascular diseases including ED. Decreased vascular NO has been linked to abdominal obesity, smoking and high intakes of fat and sugar, which all cause oxidative stress. Men with ED have decreased vascular NO and circulating and cellular antioxidants. Oxidative stress and inflammatory markers are increased in men with ED, and all increase with age. Exercise increases vascular NO, and more frequent erections are correlated with decreased ED, both in part due to stimulation of endothelial NO production by shear stress. Exercise and weight loss increase insulin sensitivity and endothelial NO production. Potent antioxidants or high doses of weaker antioxidants increase vascular NO and improve vascular and erectile function. Antioxidants may be particularly important in men with ED who smoke, are obese or have diabetes. Omega-3 fatty acids reduce inflammatory markers, decrease cardiac death and increase endothelial NO production, and are therefore critical for men with ED who are under age 60 years, and/or have diabetes, hypertension or coronary artery disease, who are at increased risk of serious or even fatal cardiac events. Phosphodiesterase inhibitors have recently been shown to improve antioxidant status and NO production and allow more frequent and sustained penile exercise. Some angiotensin II receptor blockers decrease oxidative stress and improve vascular and erectile function and are therefore preferred choices for lowering blood pressure in men with ED. Lifestyle modifications, including physical and penile-specific exercise, weight loss, omega-3 and folic acid supplements, reduced intakes of fat and sugar, and improved antioxidant status through diet and/or supplements should be integrated into any comprehensive approach to maximizing erectile function, resulting in greater overall success and patient

    Lower urinary tract symptoms (LUTS) in males can reduce patients' quality of life (QoL) and affect sexual function and satisfaction. Although this has been documented in the US, Canada, Germany, Italy, UK, and Sweden, data are limited on the effects of LUTS on QoL and sexual function in Asian men. The present subgroup analysis of an Internet-based survey correlated the incidence of male LUTS by severity and category with self-assessed QoL and sexual function and satisfaction measures. Males aged ≥40 years were randomly selected from consumer survey panels in China, Taiwan, and South Korea. LUTS were defined using the International Continence Society (ICS) 2002 symptom definitions; symptom severity was assessed by the International Prostate Symptom Score (IPSS). The effect of LUTS on QoL was assessed using Patient Perception of Bladder Condition (PPBC) and IPSS QoL scores. Sexual function and satisfaction were assessed using the International Index of Erectile Function (IIEF). Men with moderate-to-severe LUTS and overlap of voiding, storage, and post-micturition symptom categories reported dissatisfaction with their QoL and sexual function. LUTS severity was negatively correlated with IIEF scores. Overlap of LUTS categories had a greater effect on QoL and sexual satisfaction than the incidence of just 1 LUTS. The findings of the present study suggest that LUTS is prevalent in >60% of Asian males aged ≥40 years and is associated with reduced QoL and sexual function, particularly in those with overlap of LUTS categories and greater symptom severity. © 2018 The Authors.

    Curcumin is an inducer of heme oxygenase enzyme-1 (HO-1) that is involved in erectile signaling via elevating cyclic guanosine monophosphate (cGMP)levels. To assess the effect of oral administration of a water-soluble long-acting curcumin derivative on erectile signaling. Two hundred and thirty six male white albino rats were divided into four groups; group 1 (N = 20) includes control. Group 2 (N = 72) was equally divided into four subgroups; subgroup 1 received pure curcumin (10 mg/kg), subgroup 2 received the long-acting curcumin derivative (2 mg/kg), subgroup 3 received the long-acting curcumin derivative (10 mg/kg), and subgroup 4 received sildenafil (4 mg/kg). Subgroups were sacrificed after the first, second, and third hour. Group 3 (N = 72) was equally divided into the same four subgroups already mentioned and were sacrificed after 24 hours, 48 hours, and 1 week. Group 4 (N = 72) was subjected to intracavernosal pressure (ICP) measurements 1 hour following oral administration of the same previous doses in the same rat subgroups. Cavernous tissue HO enzyme activity, cGMP, and ICP. In group 2, there was a significant progressive maintained elevation of HO activity and cGMP tissue levels starting from the first hour in subgroups 3 and 4, whereas, the rise in HO activity and cGMP started from second hour regarding the other rat subgroups. Sildenafil effect decreased after 3 hours. In group 3, there was a significant maintained elevation of HO activity and cGMP tissue levels extended to 1 week as compared to controls for all rat subgroups that received both forms of curcumin. In group 4, long-acting curcumin derivative exhibited more significant potentiation of intracavernosal pressure as compared to control and to the pure curcumin. Water-soluble long-acting curcumin derivative could mediate erectile function via upregulating cavernous tissue cGMP. © 2009 International Society for Sexual Medicine.

    Inflammatory bowel disease (IBD) is likely to have an impact on sexual function because of its symptoms, like diarrhea, fatigue, and abdominal pain. Depression is commonly reported in IBD and is also related to impaired sexual function. This study aimed to evaluate sexual function and its association with depression among patients with IBD compared with controls. IBD patients registered at two hospitals participated. The control group consisted of a general practitioner practice population. The web-based questionnaire included the Female Sexual Function Index (FSFI) for women and the International Index of Erectile Function (IIEF) for men. Other variables evaluated were depression, disease activity, IBD-related quality of life, body image, and fatigue. In total, 168 female and 119 male patients were available for analysis (response rate 24%). Overall, patients with IBD did not significantly differ in prevalence of sexual dysfunctions from controls: female patients 52%, female controls 44%, male patients and male controls both 25%. However, men and women with an active disease scored significantly lower than patients in remission and controls, indicating impaired sexual functioning during disease activity. Significant associations were found between active disease, fatigue, depressive mood, quality of life, and sexual function for both male and female patients. The association between disease activity and sexual function was totally mediated by depression. Male and female IBD patients with an active disease show impaired sexual function relative to patients in remission and controls. Depression is the most important determinant for impaired sexual function in IBD. © 2015 International Society for Sexual Medicine.

    The venom of the spider Phoneutria nigriventer contains several toxins that have bioactivity in mammals and insects. Accidents involving humans are characterized by various symptoms including penile erection. Here we investigated the action of Tx2-6, a toxin purified from the P. nigriventer spider venom that causes priapism in rats and mice. Erectile function was evaluated through changes in intracavernosal pressure/mean arterial pressure ratio (ICP/MAP) during electrical stimulation of the major pelvic ganglion (MPG) of normotensive and deoxycorticosterone-acetate (DOCA)-salt hypertensive rats. Nitric oxide (NO) release was detected in cavernosum slices with fluorescent dye (DAF-FM) and confocal microscopy. The effect of Tx2-6 was also characterized after intracavernosal injection of a non-selective nitric oxide synthase (NOS) inhibitor, L-NAME. Subcutaneous or intravenous injection of Tx2-6 potentiated the elevation of ICP/MAP induced by ganglionic stimulation. L-NAME inhibited penile erection and treatment with Tx2-6 was unable to reverse this inhibition. Tx2-6 treatment induced a significant increase of NO release in cavernosum tissue. Attenuated erectile function of DOCA-salt hypertensive rats was fully restored after toxin injection. Tx2-6 enhanced erectile function in normotensive and DOCA-salt hypertensive rats, via the NO pathway. Our studies suggest that Tx2-6 could be important for development of new pharmacological agents for treatment of erectile dysfunction. PMID:18397797

    Little is known regarding how diabetic men with erectile dysfunction (ED) differ from the general population of impotent men. The primary objective of this study was to compare disease-specific health-related quality of life (HRQOL) and severity of ED in impotent men with and without diabetes. Validated functional and HRQOL questionnaires (including the International Index of Erectile Function, the Sexual Self-Efficacy Scale, and the Psychological Impact of Erectile Dysfunction scales) were administered to patients in an ED disease registry. Men with ED and a history of diabetes (n = 20) were compared with men with ED and no history of diabetes (n = 90) at baseline and at the 12-month follow-up. Diabetic impotent men reported worse erectile function and intercourse satisfaction at baseline, and ED had a greater impact on their emotional life. Diabetic men with ED had significantly different trends over time in the Erectile Function (P Emotional Life-Psychological Impact domain (P < 0.067). Impotent men with diabetes present with worse ED than nondiabetic men with ED, resulting in worse disease-specific HRQOL in the diabetic men. Although diabetic patients initially respond well to ED treatment, responses do not appear to be durable over time. Therefore, clinicians must provide longer-term follow-up when treating ED in diabetic patients.

  5. Current and future standards in evaluation of erectile dysfunction

    Full Text Available Sexual dysfunction and more specifically erectile dysfunction (ED can be a harbinger of serious occult medical conditions. ED can be considered a clinical manifestation of generalized vascular disease and therefore shares similar risk factors: aging, hypertension, diabetes mellitus, hypercholesterolemia and smoking. The initial evaluation of men with ED should be thorough. Studies of normal and abnormal penile tumescence have led to the discovery of many important pathways. The greatest medical advance in the management of male sexual dysfunction since the identification of androgens have been the discoveries that nitric oxide (NO is the primary neuro-modulator of penile smooth muscle relaxation and that oral phosphodiesterase type 5 inhibitors enhance erection quality through the NO mechanism. As a consequence of oral pharmacotherapies, the role of invasive diagnostics has diminished. Most guidelines recommend only history, physical exam and limited laboratory testing prior to instituting oral therapies for ED. In 2006 we still have unanswered questions about ED and these will frame the role of future diagnosis and therapy: can lifestyle changes alone improve erectile function; is ED a marker for the development of atherosclerotic heart disease, do lower urinary tract symptoms of benign prostatic hypertrophy and ED share a common pathway?

  6. Erectile dysfunction and central obesity: an Italian perspective

    2014-08-01

    Full Text Available Erectile dysfunction (ED is a frequent complication of obesity. The aim of this review is to critically analyze the framework of obesity and ED, dissecting the connections between the two pathological entities. Current clinical evidence shows that obesity, and in particular central obesity, is associated with both arteriogenic ED and reduced testosterone (T levels. It is conceivable that obesity-associated hypogonadism and increased cardiovascular risk might partially justify the higher prevalence of ED in overweight and obese individuals. Conversely, the psychological disturbances related to obesity do not seem to play a major role in the pathogenesis of obesity-related ED. However, both clinical and preclinical data show that the association between ED and visceral fat accumulation is independent from known obesity-associated comorbidities. Therefore, how visceral fat could impair penile microcirculation still remains unknown. This point is particularly relevant since central obesity in ED subjects categorizes individuals at high cardiovascular risk, especially in the youngest ones. The presence of ED in obese subjects might help healthcare professionals in convincing them to initiate a virtuous cycle, where the correction of sexual dysfunction will be the reward for improved lifestyle behavior. Unsatisfying sexual activity represents a meaningful, straightforward motivation for consulting healthcare professionals, who, in turn, should take advantage of the opportunity to encourage obese patients to treat, besides ED, the underlying unfavorable conditions, thus not only restoring erectile function, but also overall health.

  7. Hypogonadism and erectile dysfunction associated with soy product consumption.

    Previous research has focused on the beneficial effects of soy and its active ingredients, isoflavones. For instance, soy consumption has been associated with lower cardiovascular and breast cancer risks. However, the number of reports demonstrating adverse effects of isoflavones due to their estrogenlike properties has increased. We present the case of a 19-y-old type 1 diabetic but otherwise healthy man with sudden onset of loss of libido and erectile dysfunction after the ingestion of large quantities of soy-based products in a vegan-style diet. Blood levels of free and total testosterone and dehydroepiandrosterone (DHEA) were taken at the initial presentation for examination and continuously monitored up to 2 y after discontinuation of the vegan diet. Blood concentrations of free and total testosterone were initially decreased, whereas DHEA was increased. These parameters normalized within 1 y after cessation of the vegan diet. Normalization of testosterone and DHEA levels was paralleled by a constant improvement of symptoms; full sexual function was regained 1 y after cessation of the vegan diet. This case indicates that soy product consumption is related to hypogonadism and erectile dysfunction. To the best of our knowledge, this is the first report of a combination of decreased free testosterone and increased DHEA blood concentrations after consuming a soy-rich diet. Hence, this case emphasizes the impact of isoflavones in the regulation of sex hormones and associated physical alterations. Copyright © 2011 Elsevier Inc. All rights reserved.

All thirty-six male rats with normal sexual function were divided into three groups, i. e. normal group, model group and demasculinized group randomly according to their weights. The rats in the model group were suspended upside down in midair over the water and irritated repeatedly. Two weeks later, the sexual abilities of all rats, i. e. the times of mounting and intromitting the estrus female rats, the latent period of mounting, intromission and ejaculation, were recorded, and the number of rats that had sexual activities was also counted. And the hemorheology indices of the rats were measured. Compared with the normal rats, the latency of mounting [(152.5 +/- 24.6) s vs (42.4 +/- 9.6) s] and intromission [(437.0 +/- 67.7) s vs (130.8 +/- 39.1) s] of the model rats were longer (P 0.05). The hemorheology indices, e. g. blood viscosity, hematocrit (Hct) and red cell aggregation (RCA), of the model rats was significant higher than that of the normal and demasculinized rats (P erectile dysfunction can be made ideally with psychical stress.

    Few studies on sexuality and its correlates in adults have been conducted in Asia; most studies in Asia have focused instead on erectile dysfunction in men rather than sexuality or sexual activities. This study was conducted to evaluate the prevalence and factors associated with sexual activity and erectile dysfunction in elderly Chinese men aged 65 years and above. Sexual activity and sexual functions were assessed using the International Index of Erectile Function-5. Depressive symptoms were measured by the Chinese version of the Geriatric Depression Scale. Lower urinary tract symptoms (LUTS) were measured by the International Prostatic Symptom Score. Cross-sectional data from a large prospective cohort study of Chinese elderly men were used in this study. A questionnaire that included demographic, lifestyle, and medical risk factors and physical examination were administered to 1566 Chinese men aged between 65 to 92 years in Hong Kong. Only 30.7% of men were sexually active in the previous 6 months in this sample and among those who were sexually active, 88% had some form of erectile dysfunction. Being sexually inactive in the previous 6 months was associated with being older (odds ratio [OR] = 1.80; confidence interval [CI]: 1.56-2.09), single (OR = 1.87; CI = 1.19-2.94) and the presence of peripheral arterial disease (OR = 2.43; CI: 1.25-4.71). In multiple multinomial logistic regression, having clinically relevant depressive symptoms (OR = 3.37; CI: 1.31-8.70) and having moderate to severe LUTS (OR = 1.63; CI: 1.01-2.64) were independently associated with increased risk of having erectile dysfunction. We showed that a large proportion of elderly men were not sexually active in Hong Kong. For those who were sexually active, most suffered from some degree of erectile dysfunction. Having clinically relevant depressive symptoms and LUTS were independently associated with increased risk of erectile dysfunction.

  10. Does penile rehabilitation have a role in the treatment of erectile dysfunction following radical prostatectomy? [version 1; referees: 2 approved

    Full Text Available In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post–radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

    1994-01-01

    Yohimbine is an alkaloid derived mainly from the bark of the African tree, Pausinystalia yohimbe. Although many pharmacological properties of yohimbine have been described, at the plasma concentration attained at recommended dosages in man the predominant activity is antagonism of alpha 2-adrenoceptors. For more than 70 years yohimbine has been used as a treatment for male and female sexual difficulties. It has enjoyed a reputation as an aphrodisiac although no effect on sexual drive in humans has been adequately demonstrated. Yohimbine has been evaluated in the management of erectile disorder by means of placebo-controlled but often poorly designed trials. It does appear to have a modest therapeutic benefit over placebo, particularly in essentially psychogenic erectile disorder, and is generally well tolerated. Yohimbine is not licensed in the UK.

Erectile dysfunction (ED) is a frequent disorder that affects negatively quality of life of males suffering it. Its prevalence varies between different countries, cultures and races. The first population studies published date from early 90's and still keep their validity. All of them show the influence of age on prevalence of ED, as well as its close relationship with cardiovascular diseases. Depending on the definition used and study design prevalence varies from 10 to 52%, mainly in men between 40-70 years, with an incidence in western countries between 25-30 new cases per 1000 inhabitants year.

    Despite increasing understanding of the cerebral functional changes and structural abnormalities in erectile dysfunction, alterations in the topological organization of brain networks underlying psychogenic erectile dysfunction remain unclear. Here, based on the diffusion tensor image data of 25 patients and 26 healthy controls, we investigated the topological organization of brain structural networks and its correlations with the clinical variables using the graph theoretical analysis. Patients displayed a preserved overall small-world organization and exhibited a less connectivity strength in the left inferior frontal gyrus, amygdale and the right inferior temporal gyrus. Moreover, an abnormal hub pattern was observed in patients, which might disturb the information interactions of the remaining brain network. Additionally, the clustering coefficient of the left hippocampus was positively correlated with the duration of patients and the normalized betweenness centrality of the right anterior cingulate gyrus and the left calcarine fissure were negatively correlated with the sum scores of the 17-item Hamilton Depression Rating Scale. These findings suggested that the damaged white matter and the abnormal hub distribution of the left prefrontal and limbic cortex might contribute to the pathogenesis of psychogenic erectile dysfunction and provided new insights into the understanding of the pathophysiological mechanisms of psychogenic erectile dysfunction.

    Full Text Available The National Institute of Health defined erectile dysfunction as the persistent inability to achieve and/or to maintain an erection for a satisfactory sexual performance. Erectile dysfunction must be considered a public health problem for its high prevalence worldwide. Aetiology of erectile dysfunction can be classified as organic, psychogenic or mixed. Erectile dysfunction must be considered the first sign of many diseases. Thus, a correct diagnostic approach is essential before starting an effective therapeutic regimen. Current guidelines concerning management of erectile dysfunction agree on the great importance of anamnesis as being the basis of a correct diagnosis of erectile deficit. First level diagnostic tests, including anamnesis, validated questionnaire, routine laboratory tests and hormonal profile seem enough to make an aetiological diagnosis of erectile dysfunction and to identify and remove any erectile dysfunction (ED risk factors in most cases. First level tests should be performed, so than urologists can accurately diagnose ED and prescribe relevant treatment. Second level diagnostic evaluation includes specialistic instrumental exams that can be helpful for accurate aetiological diagnosis of erectile dysfunction. These exams, including Penile dynamic colour-duplex. Doppler ultrasonography, nocturnal penile tumescence recording, cavernosometry/cavernosography and neurological investigation, should be performed when first level diagnostic assessment is not clear, when the presence of an underlying organic pathology should be excluded in young patients with persistent ED, when veno-occlusive or neurogenic ED is suspected and when a better definition of the disease is needed.

    Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are common in diabetic men. The aim of this study was to investigate hormonal determinants, the prevalence and severity of ED and LUTS in middle-aged and elderly men with prediabetes (PD). We investigated 176 men with PD and 184 healthy peers. PD was defined according American Diabetes Association. ED according IIEF scale and LUTS according IPSS scale were assessed. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor 1 (IGF-1) were measured. The prevalence of ED in patients with PD was higher than in control group (30 versus 24%) as well as the prevalence and severity of ED and LUTS in elderly (60-80 years) and middle-aged (40-59 years) men with PD was higher than in healthy peers. In middle-aged pre-diabetic men, the more severe LUTS symptoms were associated with low TT and DHEAS, while in elderly men with low cFT and DHEAS. The higher prevalence of ED in middle-aged men with PD was associated with cFT and DHEAS, while in elderly pre-diabetic men with TT and IGF-1. The prevalence and severity of LUTS and ED symptoms were higher in pre-diabetic men than in healthy peers. Hormonal determinants of these symptoms are different in middle-aged and elderly patients with PD.

    Full Text Available ABSTRACT Purpose: Despite the nerve-sparing technique, many patients suffer from erectile dysfunction after radical prostatectomy (RP due to cavernous nerve injury. The aim of this study was to evaluate dipyridamole as a potential treatment agent of post-radical prostatectomy erectile dysfunction. Material and methods: A total of 18 male Sprague-Dawley rats were randomized into three experimental Groups (SHAM+DMSO, BCNI+DMSO and BCNI+DIP. An animal model of bilateral cavernous nerve crush injury (BCNI was established to mimic the partial nerve damage during nerve-sparing RP. After creating of BCNI, dimethyl sulphoxide (DMSO was administered transperitoneally as a vehicle to SHAM+DMSO and BCNI+DMSO Groups. BCNI+DIP Group received dipyiridamole (10mg/kg/day as a solution in DMSO for 15 days. Afterwards, rats were evaluated for in vivo erectile response to cavernous nerve stimulation. Penile tissues were also analyzed biochemically for transforming growth factor-β1 (TGF-β1 level. Penile corporal apoptosis was determined by TUNEL method. Results: Erectile response was decreased in rats with BCNI and there was no significant improvement with dipyridamole treatment. TGF-β1 levels were increased in rats with BCNI and decreased with dipyridamole treatment. Dipyridamole led to reduced penile apoptosis in rats with BCNI and there was no significant difference when compared to sham operated rats. Conclusions: Although fifteen-day dipyridamole treatment has failed to improve erectile function in rats with BCNI, the decline in both TGF-β1 levels and apoptotic indices with treatment may be helpful in protecting penile morphology after cavernous nerve injury.

    Full Text Available Background: Previous studies have supported the association between hypertension and erectile dysfunction (ED. In addition, a significant correlation between hypertension in men and ED has been well established. Objectives: The aim of this study was to investigate the prevalence of ED, its severity and other sexual function domains in hypertensive patients in Qatar. Design and Setting: Cross-sectional study conducted between January and December 2006 at the Hamad General Hospital. Subjects: Qatari and nonQatari nationals 25 to 75 years of age were approached to participate in this study, 642 (75.5% gave their consent. Materials and Methods: Qatari and nonQatari men aged 25 to 75 years who gave consent were interviewed face-to-face. Sexual function was evaluated with the International index of erectile function. Results: A total of 642 (75.5% men responded, mean age of subjects was 57.1 ± 11.9 years. The prevalence of ED in hypertensive patients was 58.3%. 21.2% of hypertensive men reported severe ED, 20.7% moderate ED and 16.4% mild ED. The comorbidities and risk factors were significantly more prominent in ED patients than in those with normal ED for hypercholesterolemia ( P =0.009, diabetes ( P =0.022 for hypertriglyceridemia ( P =0.033 and myocardial ischemia ( P =0.042. Conclusions: Our results have shown a greater prevalence of ED in the hypertensive men in the population of Qatar. The presence of another risk factor in addition to elevated blood pressure can increase the likelihood of ED.

    To identify predictors of poor quality of life among men with diabetes from a comprehensive set of sexual, clinical, socio-economic and lifestyle variables. This was a cross-sectional observational-study of 253 men with Type 2 diabetes, randomly selected from a clinic in Colombo, Sri Lanka. Erectile dysfunction was assessed using the five-item International Index of Erectile Function and quality of life was assessed using the Sri Lankan version of the 36-item short form health survey questionnaire and the disease-specific Psychological Impact of Erectile Dysfunction scale. The presence of premature ejaculation, reduced libido, socio-demographic and lifestyle data was obtained using an interviewer-administered questionnaire. Significant predictors of quality of life were identified by stepwise multivariate linear regression models for short form-36 subscales, summary scales and two scales of Psychological Impact of Erectile Dysfunction. Significant predictors on the physical summary scale of the 36-item short form were erectile dysfunction (β = 7.93, 95% CI 3.70-12.17, P 27.5 kg/m(2) (β = 9.12, 95% CI 1.38-17.44, P strong predictor of poor generic and disease-specific quality of life among other sexual and clinical variables in men with diabetes. © 2014 The Authors.

    2016-02-01

    Erectile dysfunction (ED) related to compromise of the nervous system is an increasingly common occurrence. This may be due to the multifactorial nature of ED, the myriad of disorders affecting the neurotransmission of erectogenic signals, and improved awareness and diagnosis of ED. Nevertheless, neurogenic ED remains poorly understood and characterized. Disease related factors such as depression, decreased physical and mental function, the burden of chronic illness, and loss of independence may preclude sexual intimacy and lead to ED as well. The amount of data regarding treatment options in subpopulations of differing neurologic disorders remains scarce except for men with spinal cord injury. The treatment options including phosphodiesterase inhibitors, intracavernosal or intraurethral vasoactive agents, vacuum erection devices (VED) and penile prosthetic implantation remain constant. This review discusses the options in specific neurologic conditions, and briefly provides insight into new and future developments that may reshape the management of neurogenic ED.

    Full Text Available BACKGROUND One of the most common adverse effects of diabetes mellitus, erectile dysfunction (ED remains difficult to treat despite advances in pharmacotherapeutic approaches in the field. This unmet need has brought about a late re-focus on the pathophysiology, so as to comprehend the cellular and molecular mechanism prompting ED in diabetes. Diabetes-induced ED is a need to find focuses that may prompt novel approaches for a fruitful treatment. Present study was tried to understand role of vascular and neurogenic alterations in the pathophysiology of diabetic sexual dysfunction. SUBJECTS AND METHODS The study was carried out on 17 male impotent patients with Diabetes Mellitus: 5 patients (Aged 43-56 years; mean age 48.4 had insulin-dependent DM, and 13 patients (Aged 40-62; mean age 53.5 non-insulin-dependent DM. None of the patients were on medications known to interfere with male erectile sexual function. All patients were told to give informed consent. Every participant underwent a physical examination including complete medical and sexual history and routine laboratory tests. Penile vascular assessment and assessment of nocturnal penile erections investigation were assessed in the study. RESULTS As showed in Table I. alterations in the vascular system was found in 13 (61.5% participants. Out of which moderate alteration noticed in 8 (47% and severe alteration in 5 (16% patients. Among the patients with non-insulin-dependent DM, 7 (41.1% had showed Nocturnal Penile Erections abnormalities. According to the history and also to the normal responses to the Nocturnal penile tumescence monitoring (NPTM, patients were diagnosed as having impotence of psychogenic origin. CONCLUSION Initial involvement of both arterial supply and of the neurological pathways can be of some interest, suggesting the need for an early screening of neural and vascular status even in patients without penile erectile failure. As is the case for other degenerative

    Erectile dysfunction (ED) in the older adult male is a significant problem affecting more than 75% of men over 70 years of age in the United States. Older men have an increased likelihood of developing ED due to chronic disease, comorbid conditions, and age-related changes. Research has demonstrated that while the prevalence and severity of ED increases with age, sexual desire often remains unchanged. This article discusses the clinical picture of ED, including relevant pathophysiology, clinical presentation, and evaluation and treatment options.

    Full Text Available Prostate cancer is one of the most prevalent cancers and the second leading cause of cancer-related deaths in men in the United States. A large number of patients undergo radiation therapy (RT as a standard care of treatment; however, RT causes erectile dysfunction (radiation-induced erectile dysfunction; RiED because of late side effects after RT that significantly affects quality of life of prostate cancer patients. Within 5 years of RT, approximately 50% of patients could develop RiED. Based on the past and current research findings and number of publications from our group, the precise mechanism of RiED is under exploration in detail. Recent investigations have shown prostate RT induces significant morphologic arterial damage with aberrant alterations in internal pudendal arterial tone. Prostatic RT also reduces motor function in the cavernous nerve which may attribute to axonal degeneration may contributing to RiED. Furthermore, the advances in radiogenomics such as radiation induced somatic mutation identification, copy number variation and genome-wide association studies has significantly facilitated identification of biomarkers that could be used to monitoring radiation-induced late toxicity and damage to the nerves; thus, genomic- and proteomic-based biomarkers could greatly improve treatment and minimize arterial tissue and nerve damage. Further, advanced technologies such as proton beam therapy that precisely target tumor and significantly reduce off-target damage to vital organs and healthy tissues. In this review, we summarize recent advances in RiED research and novel treatment modalities for RiED. We also discuss the possible molecular mechanism involved in the development of RiED in prostate cancer patients. Further, we discuss various readily available methods as well as novel strategies such as stem cell therapies, shockwave therapy, nerve grafting with tissue engineering, and nutritional supplementations might be used to

    Schwann cell-seeded guidance tubes have been shown to promote cavernous nerve regeneration, and the local delivery of neurotrophic factors may additionally enhance nerve regenerative capacity. The present study evaluates whether the transplantation of GDNF-overexpressing Schwann cells may enhance regeneration of bilaterally transected erectile nerves in rats. Silicon tubes seeded with either GDNF-overexpressing or GFP-expressing Schwann cells were implanted into the gaps between transected cavernous nerve endings. Six (10 study nerves) or 12 wk (20 study nerves) postoperatively, erectile function was evaluated by relaparotomy, electrical nerve stimulation, and intracavernous pressure recording, followed by ultrastructural evaluation of reconstructed nerves employing bright-field and electron microscopy. Additional animals were either sham-operated (positive control; 20 study nerves) or received bilateral nerve transection without nerve reconstruction (negative control; 20 study nerves). The combination of GDNF delivery and Schwann cell application promoted an intact erectile response in 90% (9 of 10) of grafted nerves after 6 wk and in 95% (19 of 20) after 12 wk, versus 50% (5 of 10) and 80% (16 of 20) of GFP-expressing Schwann cell grafts (p=0.02). The functional recovery was paralleled by enhanced axonal regeneration in GDNF-overexpressing Schwann cell grafts, as indicated by larger cross-sectional areas and a significantly higher percentage of neural tissue compared with GFP-transduced controls. These findings demonstrate that the time required to elicit functional recovery of erectile nerves can be reduced by local delivery of GDNF. In terms of clinical application, this enhanced nerve repair might be critical for timely reinnervation of the corpus cavernosum as a prerequisite for functional recovery in men.

    Patients with benign prostatic hyperplasia (BPH) may receive prostatic surgery due to severe lower urinary tract symptoms (LUTS). This study aimed to investigate the health-related quality of life (HRQoL), psychological well-being, and sexual function of patients with BPH after prostatic surgery and identify the predictors of HRQoL among this group of patients. This was a cross-sectional, descriptive, correlational study. A convenience sample of 94 participants was recruited from a urology center in a tertiary public hospital in Singapore. The 12-item Short Form Health Survey version 2 (SF-12v2), International Prostate Symptom Score (IPSS), Hospital Anxiety and Depression Scale (HADS), and 5-item International Index of Erectile Function (IIEF-5) were used to measure the study variables. Compared to the general population norms and the findings of similar studies conducted in western countries, this group of patients reported poorer physical health but better mental health as assessed by SF-12v2. Despite the prostatic surgery, over a quarter of the patients experienced moderate LUTS, and 13.8% experienced severe erectile dysfunction. Multiple linear regression analysis identified that LUTS (B=-0.51, p=0.02) and maximum flow rate (B=-0.23, p=0.02) predicted poor physical health, accounting for 45.9% of variance, while HADS-Anxiety (B=-1.07, p<0.01) and LUTS (B=-0.32, p=0.03) predicted poor mental health, accounting for 57.2% of variance. The physical health of BPH patients with prostatic surgery was poor, with many suffering moderate LUTS and sexual dysfunction. Special attention should be given to those patients with severe LUTS who have a low maximum flow rate or have anxiety symptoms. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Objective To compare the erectile function (EF and sexual desire (SD in men after radical cystoprostatectomy (RCP who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. Materials and Methods Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41 or orthotropic ileal neobladder substitution (n = 40. EF and SD were assessed using International Index of Erectile Function (IIEF questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. Results Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006. At 12-month postoperative period, 4 (9.8% and 14 (35.0% patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006. Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8% and 7 (17.1% patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02. At 12-month follow up period 24.4% of the ileal conduit and 45.0% of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01. Conclusion When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

    Background Erectile dysfunction (ED) has a profound impact on the quality of life of many men. Many risk factors are associated with ED, such as aging, sex hormone levels, hypertension, cardiovascular diseases, and diabetes mellitus. Arsenic exposure could damage peripheral vessels and increase the risk of cardiovascular disease. However, the relationship between arsenic exposure and ED has seldom been evaluated. Objectives In this study we aimed to investigate whether exposure to arsenic enhances the risk of ED. Methods We recruited 177 males ≥ 50 years of age through health examinations conducted in three hospitals in Taiwan. We used a questionnaire (International Index of Erectile Function-5) to measure the level of erectile function. Sex hormones, including total testosterone and sex hormone–binding globulin, were determined by radioimmunoassay. We used another standardized questionnaire to collect background and behavioral information (e.g., cigarette smoking; alcohol, tea, or coffee drinking; and physical activity). Results The prevalence of ED was greater in the arsenic-endemic area (83.3%) than in the non–arsenic-endemic area (66.7%). Subjects with arsenic exposure > 50 ppb had a significantly higher risk of developing ED than those with exposure ≤ 50 ppb, after adjusting for age, cigarette smoking, diabetes mellitus, hypertension, and cardiovascular disease [odds ratio (OR) = 3.4]. Results also showed that the risk of developing severe ED was drastically enhanced by arsenic exposure (OR = 7.5), after adjusting for free testosterone and traditional risk factors of ED. Conclusions Results suggested that chronic arsenic exposure has a negative impact on erectile function. PMID:18414639

    OBJECTIVE To assess health-related quality of life (HRQOL) in men with erectile dysfunction. DESIGN Descriptive survey with general and disease-specific measures. The instrument contained three established, validated HRQOL measures, a validated comorbidity checklist, and sociodemographics. The RAND 36-Item Health Survey 1.0 (SF-36) was used to assess general HRQOL. Sexual function and sexual bother were assessed using the UCLA Prostate Cancer Index. The marital interaction scale from the Cancer Rehabilitation Evaluation System Short Form (CARES-SF) was used to assess each patient's relationship with his sexual partner. SETTING Urology clinics at a university medical center and the affiliated Veterans Affairs (VA) Medical Center. PARTICIPANTS Thirty-five (67%) of 54 consecutive university patients presenting for erectile dysfunction and 22 (42%) of 52 VA patients who were awaiting a previously prescribed vacuum erection device participated. MAIN RESULTS The university respondents scored slightly lower than population normals in social function, role limitations due to emotional problems, and emotional well-being. The VA respondents scored lower than expected in all eight domains. Scores for the VA population were significantly lower than those for the university population in physical function, role limitations due to physical problems, bodily pain, and social function. A significant correlation was seen between marital interaction and sexual function (r = −.33, p = .01) but not between marital interaction and sexual bother (r = −.15, p = .26) in the total sample. Sexual function also correlated significantly with general health perceptions (r = .34, p = .01), role limitations due to physical problems (r = .29, p = .03), and role limitations due to emotional problems (r = .30, p = .03). Sexual bother did not correlate with any of the general HRQOL domains. Affluent men reported better sexual function (p = .03). CONCLUSIONS The emotional domains of the SF-36 are

    The prevalence and associated factors of erectile dysfunction (ED) in Human Immunodeficiency Virus (HIV)-infected men remain controversial. The authors evaluated ED, clinical, and emotional variables in a group of 501 HIV-infected men in a cross-sectional 4-month observational study. ED was assessed using the International Index of Erectile Function-5 and emotional status using the Hospital Anxiety and Depression (HAD) questionnaire. Median age (interquartile range) was 42 (35, 48) years. Time since HIV diagnosis was 6.3 (2.6, 17.1) years, 92% were taking antiretroviral treatment and 81.8% had an HIV-RNA viral load emotional status seemed to play a fundamental role in its presence.

    Full Text Available Prostate cancer (PC treatment is a pressing problem both inRussiaand worldwide. According to data for Saint-Petersburg, from 1990 to 2002 morbidity increase rate for PC was 141.3 %. Even after nerve-sparing radical prostatectomy (RP erectile dysfunction of some level is observed in 65–75 % of patients. During follow-up examination, data on sexual history were gathered including information on past and current sexual contacts. A questionnaire based on the International Index of Erectile Function was used which allows to evaluate different parameters of sexual function (sexual drive, erection, orgasm, ejaculation, sexual act, and satisfaction with sexual relationships, as well as determine treatment effectiveness. We performed combined two-stage treatment of erectile dysfunction in patients with PC after RP. At the first stage, phosphodiesterase type 5 inhibitors (sildenafil 100 mg were used. If the drug was ineffective, the second stage was initiated (intracavernosal alprostadil injections. Drug effectiveness, complications, patient compliancy were evaluated.

    Male sexual dysfunction is a significant international public health issue affecting both middle-aged and older adults. To date, however, no studies have compared age differences in psychiatric issues, frequency of sexual activity and treatment recommendations between older and middle-aged male military Veterans seeking treatment for erectile dysfunction (ED) in the U.S.A. Data were collected between 1982 and 2003 at the Palo Alto Veterans Affairs Andrology Clinic. The 1,250 participants, aged 22 to 87 years (median = 63), completed a semi-structured interview. Using multiple linear regressions, we examined age differences in five domains: medical and endocrine risk factors; psychiatric and psychosocial risk factors; frequency of sexual behaviors; self-reported and objectively measured erectile function; and treatment recommendations. Compared with middle-aged adults, older adults were more likely to present for ED treatment with medical risk factors and were more often recommended a vacuum pump treatment. Middle-aged male Veterans were more likely to experience psychiatric risk factors for ED and were more sexually active than older Veterans. Despite greater objective erectile ability in middle-aged adults, there were no age differences in maximum self-reported erectile functioning. These results provide some evidence of age-related characteristics and treatment needs of male patients seeking treatment for sexual dysfunction. We encourage health care professionals working with adults across the lifespan to consider ways to individualize psychoeducation and brief psychotherapy for the treatment of ED to the specific needs of the patient, which may vary between middle-aged and older cohorts of patients.

    Since the origin, the man tried by all possible means to restor his erectile capacity. The obscurantism prevailed for a long time. We had to wait up to the turn of the 19th Century with Freud to get that things evolve a little bit. In the Fifties, the first penile prostheses were developed by Goodwin and Scott. In the Sixties, the behavioral therapies by Masters and Johnson. The Eighties represent the pharmacological revolution with the discovery of the effects of papaverin by Virag, then the E1 prostaglandin by Ishii, as well as the inhibitors of the 5 phospho di esterase (sildenafil, vardenafil, tadalafil) following studies on nitric oxide by Ignarro, Nobel Prize of medicine in 1998.

    Full Text Available Erectile dysfunction (ED is the inability to achieve and maintain an erection sufficient for satisfactory sexual intercourse. It is the most frequent sexual dysfunction in elderly men and its prevalence increases with age. Ever since ED was recognized as a real health problem, several treatment options became available and some of them proved to be very efficient. PDE5 inhibitors are the mainstay treatment of ED. However, other treatment options such as intracorporal injections, surgery, vacuum devices and prosthesis are also available for patients who are unresponsive to PDE5 inhibitors. Since none of the treatment options available so far has proven ideal, research in the field of sexual medicine continues. The aim of this paper is to review the most advances in the treatment of ED.

    Some men with premature ejaculation (PE) and normal erectile function record contradictory response/s to The Sexual Health Inventory for Men (SHIM) and may be incorrectly categorized as suffering from erectile dysfunction (ED). The aim of this study was to evaluate the frequency of false positive SHIM diagnosis of ED in men with lifelong PE. SHIM, stopwatch intravaginal ejaculation latency time (IELT). A prospective observational study of men with normal erectile function and lifelong PE, diagnosed using the ISSM definition of lifelong PE, was conducted. The SHIM was self-administered at Visit 1. Mean per subject stopwatch IELT was determined from four subsequent intercourse attempts. Seventy-eight subjects with a mean age of 33.2 +/- 8.3 years and a geometric mean IELT of 15.9 +/- 2.3 seconds were enrolled. The mean SHIM score for all subjects was 20.4 +/- 6.0. Fifty-two subjects (66.7%) have SHIM scores of >21 (mean 24.3 +/- 1.1), consistent with normal erectile function, and a geometric mean IELT of 18.3 +/- 2.2 seconds. Twenty-six subjects (33.3%) had SHIM scores IELT of 10.5 +/- 2.3 seconds. The incidence of false positive SHIM diagnosis of ED (SHIM IELT. Although the geometric mean IELT for subjects with SHIM scores 21, there were no significant differences between the geometric mean IELT or the IELT distribution of all subjects vs. the normal erectile function IELT (SHIM > 21) cohort. This study demonstrates a 33.3% false positive SHIM diagnosis of ED in men with PE. This is likely to limit subject recruitment in clinical trials by exclusion of subjects with low-range IELTs but is unlikely to result in significantly different baseline IELTs or IELT distributions.

    A hypervascularization syndrome following arterialization of the deep dorsal vein of the penis to amend venous erectile impotence is a rare cause of penile ulcers that has not previously been described in the dermatological literature. Arterialization is performed by installing a shunt from the inferior epigastric artery or a venous bypass from the femoral artery to the deep dorsal vein of the penis, resulting in a blockage of venous outflow and in retrograde inflow into the corpora cavernosa. Complications arise as a result of persistently elevated blood pressure in the deep venous system and the erectile tissue in 10-20% of cases and are most often linked to dilatation of the shunt: the consequences are enlargement and induration of the glans, hazard of phimosis and paraphimosis, pulsation of the penis, micturation difficulties and, ultimately, ulceration of the glans. Surgical reduction of the arterial inflow ("banding" of the shunt) is the only therapeutic procedure that reduces hypervascularization without compromising the newly gained erectile function.

    Objective: To determine the frequency of erectile dysfunction in married male Type-2 diabetic patients. Methods: The cross-sectional observational study was carried out at the Endocrinology, Diabetes and Metabolic Diseases Unit Hayatabad Medical Complex, Peshawar, from July 2011 to Apr 2012, comprising 217 male married Type-2 diabetic patients. Serum samples were assayed for blood glucose, lipid profile and glycated haemoglobin A1c. Body mass index and waist-to-hip ratio was calculated. Erectile dysfunction was assessed by Sexual Health Inventory for Men questionnaire. SPSS 18 was used for statistical analysis. Results: A total of 217 patients were initially interviewed. The mean age was 43.1+-8.160 years. The frequency of drectile dysfunction increased with age, duration of patients and increased body mass index. Overall, 6 (2.8%) patients had no erectile dysfunction, 37 (17.1%) had mild, 82 (37.8%) mild to moderate; 47 (21.7%) moderate; and 45 (20.7%) severe. Higher HbA1c levels and atherogenic dyslipidaemia were associated with erectile dysfunction. Conclusion: Poor glycaemic control was associated with increased erectile dysfunction risk. Duration of diabetes, older age, increased body mass index are associated with increased incidence of the condition in patients with diabetes. Intensive lifestyle changes in the beginning can add to the better management of Type-2 diabetes and prevention of erectile dysfunction. (author)

    Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. During 2005 - 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3-11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0-8) vs 10 (IQR 6-14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3-12) vs 2 (IQR 1-4); p = .02]. Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

    We studied the possible correlation between age, testosterone deficiency, cavernosal fibrosis and erectile dysfunction (ED). 47 patients with ED were enrolled between September 2010 and October 2011. IIEF-EF score, NPTR test using the Rigiscan method, total and free testosterone levels, and cavernosum biopsy were carried out on all patients. Patients aged 65 or over were defined as Old Age (OA) while patients under 65 were defined Young age (YA). The strength of the relationships found was estimated by Odds Ratio. 74% of patients with values of over 52% collagen fibers in the corpora cavernosa were found to have organic ED. A significant difference was found in age, percentage of collagen fibers, testosterone levels between patients with Positive Rigiscan (PR) and Negative Rigiscan (NR). Hypotestosteronaemia increased the risk of ED with PR (OR: 21.4, 95% CI: 20.2-22.6) and in both young age patients (OR: 4.3, 95% CI: 2.4-6.2) and old age patients (OR: 15.5, 95% CI: 13.4-17.6). Moreover cavernosal fibrosis increased the risk of ED with PR in both young age patients (OR: 8.2, 95% CI: 6.4-10.0 and old age patients (OR: 24.6, 95% CI: 20.8-28.4). This study demonstrates a strong association among age, testosterone deficiency, cavernosal fibrosis and ED with PR. Age, testosterone deficiency and cavernosal fibrosis are potentially correctable factors of cavernosal fibrosis and organic ED. Further, prospective studies are needed to evaluate if testosterone treatment, alone or in association with PDE5 inhibitors, may lower the risk of cavernosal fibrosis or decrease the severity the fibrosis in ED patients.

    Full Text Available Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients′ sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25 represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25. Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15. Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15, orgasmic function (IIEF-9 and -10, sexual desire (IIEF-11 and -12, intercourse satisfaction (IIEF-6-8, and overall satisfaction (IIEF-13 and -14. Then, we also used Quality of Erection Questionnaire (QEQ, Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS and Self-Esteem and Relationship (SEAR to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

    oxide donors, guanylate cyclase activators, potassium channel openers and Rho-kinase inhibitors with the potential to overcome some limitations of the existing measures offer significant promise of clinical application in refractory and resistant cases. The TriMix preparations usually contain PGE1, papaverine and phentolamine in formulation compounded in pharmacies. Several clinical studies have also tested the efficacy of yohimbine, L-arginine, cyclic adenosine monophosphate activators, melanocortin-stimulating hormone analogs, endothelin antagonists in addition to vasoactive intestinal polypeptide and calcitonin gene related peptide with variable success rates. Trazodone, a serotonin antagonist and reuptake inhibitor was shown to improve premature ejaculation and erectile function in psychogenic cases of ED. Cloning of inducible nitric oxide synthase has opened a new era in the use of gene therapy for ED and the day for stem cells therapy and autologous penile tissue implants is not too far. Thus, ongoing research worldwide will continue to define new roles for various modalities targeted at specific sites in the erectile pathway and these advances will ultimately enable the clinicians to make the most appropriate therapeutic or other selections for individual patients including possible permanent reversal of organic ED.

    Full Text Available Increased cardiovascular risk has been associated with reduced response to proerectile drugs. The Italian Society of Andrology and Sexual Medicine (SIAMS promoted an independent, multicenter study performed in 604 men (55 ± 12 yrs suffering from erectile dysfunction (ED to assess multiple health outcomes and response to 6-month vardenafil challenge in a real-life setting. Overall, 30.8% men had metabolic syndrome. Cardiovascular risk stratification revealed a greater number of ED subjects with moderate risk of a major adverse cardiovascular event than the general population (P<0.01. Age-adjusted pulse pressure was positively correlated with ED severity and negatively with androgens and waist circumference (P<0.01. A decline in total testosterone was observed with increasing arterial pulse pressure (P<0.05, which was not accompanied by compensatory LH rise. Follow-up on 185 men treated with vardenafil in an nonrandomized, open, single-arm trial documented a significant rise in IIEF-5 (delta = 6.1 ± 4.8 that was maintained in men with high cardiovascular risk. Mild adverse events occurred in <5%, with no differences between cardiovascular risk classes. In summary, ED is a frequent symptom in patients with an elevated, but often unknown, risk of future cardiovascular events. Androgens predict vascular resistance in ED patients. Vardenafil’s response and safety profile were preserved in subjects with higher cardiovascular risk.

    Full Text Available Robot-assisted laparoscopic prostatectomy (RALP has emerged as the most common treatment for localized prostate cancer. With improved surgical precision, RALP has produced hope of improved potency rates, especially with the advent of nerve-sparing and other modified techniques. However, erectile dysfunction (ED remains a significant problem for many men regardless of surgical technique. To identify the functional outcomes of robotic versus open and laparoscopic techniques, new robotic surgical techniques and current treatment options of ED following RALP. A Medline search was performed in March 2014 to identify studies comparing RALP with open retropubic radical prostatectomy (RRP and laparoscopic radical prostatectomy, modified RALP techniques and treatment options and management for ED following radical prostatectomy. RALP demonstrates adequate potency rates without compromising oncologic benefit, with observed benefit for potency rates compared with RRP. Additionally, specific surgical technical modifications appear to provide benefit over traditional RALP. Phosphodiesterase-5 inhibitors (PDE5I demonstrate benefit for ED treatment compared with placebo. However, long-term benefit is often lost after use. Other therapies have been less extensively studied. Additionally, correct patient identification is important for greatest clinical benefit. RALP appears to provide beneficial potency rates compared with RRP; however, these effects are most pronounced at high-volume centers with experienced surgeons. No optimal rehabilitation program with PDE5Is has been identified based on current data. Additionally, vacuum erection devices, intracavernosal injections and other techniques have not been well validated for post RALP ED treatment.

    In Nigeria, the prevalence of erectile dysfunction (ED) among patients attending primary care clinics, age-standardized to the U.S. population in 2000 is 57.4%. This is considered high enough to warrant the attention of scientist for critical studies and analysis. The high ED prevalence is associated with etiologies such as psychosexual factors, chronic medical conditions, and some lifestyles. ED constitutes a major public health problem, influencing the patient's well-being and quality of life. It also leads to broken homes and marriages, psychological, social, and physical morbidity. To give an account of various ED management options in Nigeria. Review of peer-reviewed literature, questionnaire, and ethnobotanical survey to some indigenous herb sellers and herbalists. Cross cultural perspectives of ED management in Nigeria. The review suggests that traditional (phytotherapy, zootherapy, and occultism) and nontraditional, orthodox practice (drug therapy, psychological, and behavioral counseling) are applicable to ED management in Nigeria. This review should help in creating awareness into various options available for managing ED in the country, but does not recommend self medication of any form, be it the use of orthodox or herbal remedy.

    Sexual dysfunction, particularly erectile dysfunction (ED), is common in men with type 2 diabetes, occurring in up to 75% of cases. The prevalence of hypogonadism is also high in men with diabetes and low testosterone is associated with both sexual dysfunction and a reduced response to oral therapy for ED. This study aimed to determine the effect of testosterone replacement with long-acting Testosterone Undecanoate (TU) on sexual function, mood and quality of life vs. placebo over a treatment period of 30 weeks followed by 52 weeks of open-label medication. The study was conducted in a primary care population of men with type 2 diabetes attending their primary care physician for routine visits. The male diabetic populations of seven general practices were screened at routine diabetes visits to detect symptomatic men with total testosterone levels of 12 nmol/L or less or with free testosterones of 250 pmol/L or less. Two hundred eleven men were screened. A double-blind placebo-controlled study was conducted in 199 men with type 2 diabetes and hypogonadism treated for 30 weeks with either 1,000 mg of TU or matching placebo followed by 52-week open-label follow on. The primary outcome measure, International Index of Erectile Function (IIEF), was used to evaluate sexual dysfunction, and the Ageing Male Symptom (AMS), Hospital Anxiety and Depression Scale, and Global Efficacy Question were used as secondary outcome measures to assess mood and self-reported quality of life. Testosterone replacement therapy with long-acting TU improved all domains of sexual function at 30 weeks (erectile function [EF], P = 0.005; intercourse satisfaction, P = 0.015; sexual desire, P = 0.001; overall satisfaction, P = 0.05; and orgasm, P = 0.04), with benefit as early as 6 weeks. Improvements in AMS score were significant in men without depression (P = 0.02) and the presence of depression at baseline was associated with marked reduction in response to both sexual function and psychological

  2. A new therapeutic approach for erectile dysfunction: Low intensity shockwaves

    Full Text Available Erectile dysfunction is the inability to achieve or sustain a penile erection for vaginal penetration and satisfactory sexual performance. It is the second most frequent problem of sexual dysfunction in men, after premature ejaculation, with an approximate prevalence rate of 30%. Most cases of erectile dysfunction have an organic origin, mostly vascular diseases, but it is also associated with psychological, neurological, and hormonal factors, or with structural alterations of the penis. Therapy with 5-phosphodiesterase inhibitors has been clinically effective, but some patients do not respond to it. Lowintensity shock waves may improve penile vascularity and blood flow, leading to better erections, and improvement of the quality of sexual performance. In this review several studies are included that show the effectiveness of this treatment for erectile dysfunction.

    Abstract Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.

    To explore relationships between erection hardness and other outcomes in men with erectile dysfunction (ED). Pooled analyses were conducted on 27 randomized, double-blind, placebo-controlled trials and six open-label trials from the worldwide sildenafil database. Outcomes included erection hardness graded subjectively, hardness and sexual satisfaction questions from the International Index of Erectile Function, general and sexually-specific emotional well-being from the self-esteem and relationship questionnaire, and the erectile dysfunction inventory of treatment satisfaction. Hardness outcomes improved (with a possible dose-response relationship for the achievement of fully hard and rigid erections) and correlated positively with the other outcomes. Sildenafil 100 mg produced optimal erection hardness (fully hard and rigid erections) in a substantial proportion of men with ED. Because optimal erection hardness correlated positively with some emotional well-being and satisfaction outcomes, sildenafil 100 mg may be the most appropriate dosage for treatment of ED for most men.

    A review of the current state of knowledge is made on sonographic evaluation of penile in patients with erectile dysfunction. This sonography is developed with high resolution ultrasound on gray scale, combined with color Doppler ultrasonography; which the arteries of penile are examined before and during the erection. The penile ultrasonography has meant an important tool in the evaluation of specific patients who have submitted erectile dysfunction, particularly, in those with record of trauma and history of Peyronie's disease. In addition, through a sonographic evaluation has permitted to prove manifestations of the pathophysiological phenomena of the patient in order to establish their classification and guide their treatment [es

    This paper reports on a new functional approach, used to investigate the dynamic contrast enhancement of the penis. The inflow of Gd-DTPA in penile tissue was observed at 10-second intervals during two-dimensional FLASH MR imaging. Two dimensional FLASH gradient-echo sequences were applied in a coronal orientation through the most anterior part of the symphysis. Twelve to 15 minutes after intracavernosal injection of 20 μg of prostaglandin E1 or 25 mg of papaverine, enhancement of signal intensity in the corpora cavernosa was determined every 10 seconds for 3.5 minutes. One additional late image was obtained 10 minutes after injection. Seventy-five investigations were performed in 56 patients with proved organic erectile dysfunction. Calculated time-related Gd-DTPA uptake and intracavernosal distribution depend closely on etiology. Well-defined functional inflow patterns give hints as to the pathophysiologic cause of erectile dysfunction

    Erectile dysfunction (ED) caused by pelvic injuries is a common complication of civil and battlefield trauma with multiple neurovascular factors involved, and no effective therapeutic approach is available. To test the effect and mechanisms of low-energy shock wave (LESW) therapy in a rat ED model induced by pelvic neurovascular injuries. Thirty-two male Sprague-Dawley rats injected with 5-ethynyl-2'-deoxyuridine (EdU) at newborn were divided into 4 groups: sham surgery (Sham), pelvic neurovascular injury by bilateral cavernous nerve injury and internal pudendal bundle injury (PVNI), PVNI treated with LESW at low energy (Low), and PVNI treated with LESW at high energy (High). After LESW treatment, rats underwent erectile function measurement and the tissues were harvested for histologic and molecular study. To examine the effect of LESW on Schwann cells, in vitro studies were conducted. The intracavernous pressure (ICP) measurement, histological examination, and Western blot (WB) were conducted. Cell cycle, Schwann cell activation-related markers were examined in in vitro experiments. LESW treatment improves erectile function in a rat model of pelvic neurovascular injury by leading to angiogenesis, tissue restoration, and nerve generation with more endogenous EdU(+) progenitor cells recruited to the damaged area and activation of Schwann cells. LESW facilitates more complete re-innervation of penile tissue with regeneration of neuronal nitric oxide synthase (nNOS)-positive nerves from the MPG to the penis. In vitro experiments demonstrated that LESW has a direct effect on Schwann cell proliferation. Schwann cell activation-related markers including p-Erk1/2 and p75 were upregulated after LESW treatment. LESW-induced endogenous progenitor cell recruitment and Schwann cell activation coincides with angiogenesis, tissue, and nerve generation in a rat model of pelvic neurovascular injuries.

    Penile revascularization is a surgical treatment option for erectile dysfunction (ED) in healthy individuals due to a focal arterial occlusion in the absence of generalized vascular disease. Most described failures have been attributed to graft stenosis or disruption of the anastomosis. We report a novel phenomenon called Penile Artery Shunt Syndrome that contributed to persistent ED in a patient after penile microvascular arterial bypass surgery. A 26-year-old man presented for evaluation of long-standing ED, which was attributed to trauma sustained 12 years earlier. He had difficulty obtaining and maintaining erections despite oral pharmacotherapy. Clinical data related to the case were studied, analyzed, and reviewed with urologic and radiologic specialists at multiple centers that collaborated in the care of this patient. Penile duplex ultrasound peak systolic velocities and five-item International Index for Erectile Function questionnaire scores were the main outcome measures. Initial diagnostic workup of the patient confirmed severe insufficiency of the left cavernosal artery, with no evidence of venous leak. The patient underwent penile microvascular arterial bypass surgery with anastomosis of the left inferior epigastric artery to the left dorsal penile artery. The patient had persistence of severe ED despite patent anastomosis by penile duplex ultrasound. Subsequent arteriography revealed an arterial shunt due to an aberrant obturator artery arising from the donor inferior epigastric artery. The patient underwent embolization of the aberrant obturator artery, with resolution of the shunt and marked improvement in erectile function. The presence of an aberrant obturator artery arising from the inferior epigastric artery may predispose to persistent ED after revascularization due to the creation of a shunt phenomenon. Pelvic arteriography may be useful in identifying anomalous anatomic considerations prior to penile revascularization and to evaluate patients

    Quality of life in hemodialysis patients has been associated with treatment outcomes. We explored the impact of erectile dysfunction on quality of life in a cohort of hemodialysis subjects. A random sample of 302 Philadelphia area hemodialysis (HD) subjects was enrolled using a cross-sectional design. Subjects completed a self-administered questionnaire including items on sexual function, past medical history, and quality of life. Linear regression (accounting for sampling design by weighted estimation methods) was used to examine the associations between various measures of quality of life (the dependent variables) and erectile dysfunction (ED) and other variables (the predictor variables). We found the emotional domains of the SF-36, a multi-purpose, short-form health survey with 36 questions, to be more profoundly associated with ED than the physical domains. Using the physical and mental components of the SF-12, a new 12-item short form health survey as predictors of ED, only the mental composite score (MCS) was statistically significant after adjusting for age and diabetes (P = 0.008). Subjects with ED had significantly lower quality of life mean scores. In particular, ED was associated with poorer social interaction (mean score difference, -10.3, adjusted P emotional well-being (-12.9, adjusted P = 0.005), more role limitations due to emotional problems (-22.9, adjusted P = 0.01), and poorer social function (-17.8, P = 0.001). Recent advances in therapies for ED warrant that the diagnosis and treatment of erectile dysfunction be included in the global health assessment by the nephrologists and primary care providers of patients with renal insufficiency, as it may improve the quality of life of patients.

    Erectile dysfunction (ED) is a complication of diabetes, condition responsible for causing endothelial dysfunction (EDys) and hampering repair mechanisms. However, scarce information is available linking vasculogenesis mediated by Endothelial Progenitor Cells (EPCs) and diabetes-associated ED. Furthermore, it remains to be elucidated if glycemic control plays a role on EPCs functions, EPCs modulators, and penile vascular health. We evaluated the effects of diabetes and insulin therapy on bone marrow (BM) and circulating EPCs, testosterone, and systemic/penile Stromal Derived Factor-1 alpha (SDF-1α) expression. Male Wistar rats were divided into groups: age-matched controls, 8-weeks streptozotocin-induced type 1 diabetics, and insulin-treated 8-weeks diabetics. EPCs were identified by flow cytometry for CD34/CD133/VEGFR2/CXCR4 antigens. Systemic SDF-1α and testosterone levels were evaluated by ELISA. Penile SDF-1α protein expression was assessed, in experimental and human diabetic cavernosal samples, by immunohistochemical techniques. Diabetic animals presented a reduction of BM-derived EPCs and an increase in putative circulating endothelial cells (CECs) sloughed from vessels wall. These alterations were rescued by insulin therapy. In addition, glycemic control promoted an increase in systemic testosterone and SDF-1α levels, which were significantly decreased in animals with diabetes. SDF-1α protein expression was reduced in experimental and human cavernosal diabetic samples, an effect prevented by insulin in treated animals. Insulin administration rescued the effects of diabetes on BM function, CECs levels, testosterone, and plasmatic/penile SDF-1α protein expression. This emphasizes the importance of glycemic control in the prevention of diabetes-induced systemic and penile EDys, by the amelioration of endothelial damage, and increase in protective pathways. J.

    To identify factors that predict patient satisfaction after urethroplasty by prospectively examining patient-reported quality of life scores using 3 validated instruments. A 3-part prospective survey consisting of the International Prostate Symptom Score (IPSS), the International Index of Erectile Function (IIEF) score, and a urethroplasty quality of life survey was completed by patients who underwent urethroplasty preoperatively and at 6 months postoperatively. The quality of life score included questions on genitourinary pain, urinary tract infection (UTI), postvoid dribbling, chordee, shortening, overall satisfaction, and overall health. Data were analyzed using descriptive statistics, paired t test, univariate and multivariate logistic regression analyses, and Wilcoxon signed-rank analysis. Patients were enrolled in the study from February 2011 to December 2014, and a total of 94 patients who underwent a total of 102 urethroplasties completed the study. Patients reported statistically significant improvements in IPSS (P Wilcoxon signed-rank analysis revealed significant improvements in pain scores (P = .02), UTI (P 4 cm and the absence of UTI, pain, shortening, and chordee as predictors of patient satisfaction. Multivariate analysis of quality of life domain scores identified absence of shortening and absence of chordee as independent predictors of patient satisfaction following urethroplasty (P < .01). Patient voiding function and quality of life improve significantly following urethroplasty, but improvement in voiding function is not associated with patient satisfaction. Chordee status and perceived penile shortening impact patient satisfaction, and should be included in patient-reported outcome measures. Copyright © 2017 Elsevier Inc. All rights reserved.

    In addition to a beneficial effect on exercise tolerance and an associated reduction of global cardiovascular risk, modification of physical activity has a positive effect on the quality of life, reducing, among other things, the severity of erectile dysfunction (ED). The specific nature of sexual activity, which combines the need to maintain appropriate exercise tolerance and good erection quality, prompted us to evaluate the association between exercise tolerance and severity of ED in an intervention group of subjects with ischaemic heart disease (IHD) and ED in the context of cardiac rehabilitation (CR). A total of 138 men treated invasively for IHD (including 99 treated with percutaneous coronary intervention and 39 treated with coronary artery bypass grafting) who scored 21 or less in the initial IIEF-5 test were investigated. Subjects were randomised into two groups. The study group included 103 subjects (mean age 62.07 ± 8.59 years) who were subjected to a CR cycle. The control group included 35 subjects (mean age 61.43 ± 8.81 years) who were not subjected to any CR. All subjects filled out an initial and final IIEF-5 questionnaire and were evaluated twice with a treadmill exercise test. The CR cycle was carried out for a period of 6 months and included interval endurance training on a cycle ergometer (three times a week) and general fitness exercises and resistance training (twice a week). The CR cycle in the study group resulted in a statistically significant increase in exercise tolerance (7.15 ± 1.69 vs. 9.16 ± 1.84 METs,p hypertension and smoking. A significant correlation between exercise tolerance and erection quality prior to the rehabilitation cycle indicates better erection quality in patients with better effort tolerance. The improvement in exercise tolerance did not correlate significantly with initial exercise tolerance or age of the subjects. In contrast, a significantly higher increase in erection quality was observed in younger subjects

    Patients with heart failure (HF) display erectile dysfunction (ED). However, the pathophysiology of ED during HF remains poorly investigated. This study aimed to characterize the aortocaval fistula (ACF) rat model associated with HF as a novel experimental model of ED. We have undertaken molecular and functional studies to evaluate the alterations of the nitric oxide (NO) pathway, autonomic nervous system and oxidative stress in the penis. Male rats were submitted to ACF for HF induction. Intracavernosal pressure in anesthetized rats was evaluated. Concentration-response curves to contractile (phenylephrine) and relaxant agents (sodium nitroprusside; SNP), as well as to electrical field stimulation (EFS), were obtained in the cavernosal smooth muscle (CSM) strips from sham and HF rats. Protein expression of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS) and phosphodiestarese-5 in CSM were evaluated, as well as NOX2 (gp91phox) and superoxide dismutase (SOD) mRNA expression. SOD activity and thiobarbituric acid reactive substances (TBARs) were also performed in plasma. HF rats display erectile dysfunction represented by decreased ICP responses compared to sham rats. The neurogenic contractile responses elicited by EFS were greater in CSM from the HF group. Likewise, phenylephrine-induced contractions were greater in CSM from HF rats. Nitrergic response induced by EFS were decreased in the cavernosal tissue, along with lower eNOS, nNOS and phosphodiestarese-5 protein expressions. An increase of NOX2 and SOD mRNA expression in CSM and plasma TBARs of HF group were detected. Plasma SOD activity was decreased in HF rats. ED in HF rats is associated with decreased NO bioavailability in erectile tissue due to eNOS/nNOS dowregulation and NOX2 upregulation, as well as hypercontractility of the penis. This rat model of ACF could be a useful tool to evaluate the molecular alterations of ED associated with HF.

    Full Text Available Radical prostatectomy remains the treatment of choice for localized prostate cancer in age-appropriate and health-appropriate men. Although cancer control is the most important aspect of a radical prostatectomy, minimization of postoperative morbidity, especially urinary incontinence and erectile dysfunction, is becoming a greater concern. We reviewed recent data available on Medline regarding the incidence, pathophysiology, evaluation, and treatment of incontinence and sexual dysfunction after radical prostatectomy. Health-related quality of life issues have been specifically addressed. Although low incidences of incontinence and erectile dysfunction after radical prostatectomy have been reported in the hands of experienced surgeons, the literature review revealed a great variety, with incontinence rates ranging from 0.3–65.6% and potency rates ranging from 11–87%. Several factors contribute to this wide difference, the most important being the application of a meticulous surgical technique. General and cancer-specific health-related quality of life is not being affected after radical prostatectomy. The incidence of incontinence and erectile dysfunction is higher after radical prostatectomy when compared to the incidence observed when other therapies for localized prostate cancer are applied. However, the majority of the patients undergoing radical prostatectomy would vote for the operation again. Today, avoidance of major complications after radical prostatectomy depends mostly on a high-quality surgical technique. When incontinence or erectile dysfunction persists after radical prostatectomy, the majority of the treated patients can be managed effectively by various methods.

We therefore investigated whether low BMD is associated with ED among depressive men and highlighted the possible mutual underlying factors that might give rise to these two disorders in this specific group of patients. In this cross-sectional study, 119 depressive men were recruited and their sociodemographic and clinical characteristics were obtained. Erectile function was evaluated using the 5-item International Index of Erectile Function. All patients received a calcaneal BMD scanning. Chi-square test was conducted to determine if a significant association exists between ED and low BMD. Of the study participants, ninety patients reported ED, while 29 patients reported no ED. Within the ED group, there was a significantly higher proportion of patients with low BMD compared to the non-ED group (85.6% vs. 62.1%, P = 0.006). In addition, among younger participants (i.e., aged depressive men and that only among young depressive patients, BMD was significantly lower in ED patients compared to non-ED patients. More research investigating these findings and the possible underlying mechanisms for such association are warranted.

    To present evidence that rats fed a high-fat diet could serve as a useful animal model to study both lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), as recent epidemiological studies have shown a strong association between LUTS and ED but the physiological basis behind this relationship is unknown. In all, 24 male Sprague-Dawley rats were divided into two groups: nine controls were fed a 'normal' diet and 15 were fed a high-fat diet (hyperlipidaemic rats). After 6 months all the rats had bladder and erectile functions evaluated using awake cystometry and cavernosal nerve electrostimulation, respectively. After the functional studies were completed, the penis, prostate and bladder were collected for immunohistochemical analysis. The hyperlipidaemic rats had significantly higher serum cholesterol and low-density lipoprotein than the controls (P enlargement, bladder overactivity, and ED. This rat model could be a useful research tool for understanding the common causes of LUTS and ED, as well as facilitating the development of preventive measures and better therapies to treat both conditions.

    The objective of the present study was to elucidate effects of therapeutic and preventive measures on restoration of compromised erectile function in patients with osteochondrosis of the lumbosacral spine segment (LSSS). The patients were treated using corporal and auricular acupuncture, Narzan mineral water baths, manual therapy, remedial gymnastics, and psychotherapeutic correction of sexual dysadaptation. This combined treatment resulted in the elimination of algic syndrome in 77.5% of the patients, restoration of sexual function in 62.5%, and normalization of hemodynamics in cavernous bodies in 65.2%. The functional activity of the hypothalamo-pituitary-testicular axis was normalized in 65% of the LSSS patients of strong and moderate sexual constitution. Introduction of acupuncture in the combined medicamentous therapy increased its efficiency by 15%. In 57.5% of the patients with strong and moderate sexual constitution, the restored sexual function persisted for at least 12 months.

    The aim of this study was to report and analyze the published data from randomized controlled trials (RCTs) for (i) the psychosocial outcomes associated with erectile dysfunction (ED) before treatment with a phosphodiesterase type 5 (PDE5) inhibitor; and (ii) the change in psychosocial outcomes after the use of a PDE5 inhibitor in men with ED. The method used was a prospectively designed systematic literature review of publications reported in MEDLINE via PubMed, EMBASE, the Cochrane Library, Science Citation Index Expanded, and PsychINFO from January 1, 1995 to May 14, 2012. The main outcome measures were scores on psychosocial measures in men who were treated for ED with a PDE5 inhibitor before and after treatment. A total of 1,714 publications were retrieved; 1,674 publications were excluded because they did not meet the design requirements of the review, and 40 publications (32 RCTs) were retained. Before treatment, men who participated in clinical trials reported relatively good quality of life and overall relationships, but poor sexual relationships and sexual satisfaction, diminished confidence, low self-esteem, and symptoms of depression. After treatment, there were significant improvements from baseline in most of these measures, except for overall life satisfaction and overall relationship satisfaction. ED and the treatment of ED are associated with substantially broader aspects of a man's life than just erectile functioning. This review demonstrates the importance of evaluating the psychosocial factors associated with ED and its treatment, and the importance of using standardized scales to conduct this evaluation. Further research is needed to better understand the mechanisms underlying the reciprocal relationships among physical and psychological functioning in men with ED. © 2013 International Society for Sexual Medicine.

    Erectile dysfunction (ED) is common among men with an elevated body mass index (BMI). However, a high waist circumference (WC) and low levels of physical activity may predict ED independently of BMI. We investigated the independent relationships between BMI, WC, and physical activity with ED. Subjects consisted of 3,941 adult men (age > or = 20 years) with no history of prostate cancer from the 2001-2004 National Health and Nutrition Examination Survey. Logistic regression analyses were used to examine the relative odds of ED association with categories of BMI, WC, and physical activity. Established thresholds were used to divide subjects into three WC and BMI categories. Physical activity level was divided into active (> or =150 min/week), moderately active (30-149 min/week), and inactive (inactive men had an approximately 40-60% greater odds of ED compared with active men. When all three predictors (WC, BMI, and physical activity level) were entered into the same logistic regression model, both a high WC and low physical activity level (moderately active and inactive) were independently associated with a greater odds of ED, whereas BMI level was not. Maintaining a WC level below 102 cm and achieving the recommended amount of moderate-intensity physical activity (>or =150 min/week) is associated with the maintenance of proper erectile function, regardless of BMI level. These findings suggest that the clinical screening for ED risk should include the assessment of WC and physical activity level in addition to BMI.

    Full Text Available Erectile dysfunction (ED, metabolic syndrome (MetS, and hypogonadism are closely related, often coexisting in the aging male. Obesity was shown to raise the risk of ED and hypogonadism, as well as other endocrinological disturbances with impact on erectile function. We selected 179 patients referred for ED to our andrology unit, aiming to evaluate gonadotropins and estradiol interplay in context of ED, MetS, and hypogonadism. Patients were stratified into groups in accordance with the presence (or not of MetS and/or hypogonadism. Noticeable differences in total testosterone (TT and free testosterone (FT levels were found between patients with and without MetS. Men with MetS evidenced lower TT circulating levels with an increasing number of MetS parameters, for which hypertriglyceridemia and waist circumference strongly contributed. Regarding the hypothalamic-pituitary-gonadal axis, patients with hypogonadism did not exhibit raised LH levels. Interestingly, among those with higher LH levels, estradiol values were also increased. Possible explanations for this unexpected profile of estradiol may be the age-related adiposity, other estrogen-raising pathways, or even unknown mechanisms. Estradiol is possibly a molecule with further interactions beyond the currently described. Our results further enlighten this still unclear multidisciplinary and complex subject, raising new investigational opportunities.

    The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. A multinational patient registry was used to assess long-term changes associated with TRT in middle-age and older men with hypogonadism. Comprehensive evaluations were conducted at 6, 12, 24, and 36 months after enrollment into the registry. QOL and sexual function were evaluated by validated measures, including the Aging Males' Symptom (AMS) Scale and the International Index of Erectile Function (IIEF). A total of 999 previously untreated men with hypogonadism were enrolled at 25 European centers, 750 of whom received TRT at at least one visit during the period of observation. Patients on TRT reported rapid and sustained improvements in QOL, with fewer sexual, psychological, and somatic symptoms. Modest improvements in QOL and sexual function, including erectile function, also were noted in RHYME patients not on TRT, although treated patients showed consistently greater benefit over time in all symptom domains compared with untreated patients. AMS total scores for patients on TRT were 32.8 (95% confidence interval = 31.3-34.4) compared with 36.6 (95% confidence interval = 34.8-38.5) for untreated patients (P treatment. The major strengths are the large, diverse patient population being treated in multidisciplinary clinical settings. The major limitation is the frequency of switching from one formulation to another. Overall, we confirmed the broad and sustained benefits of TRT across major QOL dimensions, including sexual, somatic, and psychological health, which were sustained over 36 months in our treatment cohort.

    Full Text Available Difficulties in sexual response have always been a cause of concern and suffering for people who suffer them, and their partners. One of the alterations of this condition in the man and that more attention demands is the erectile dysfunction, precisely for compromising in a significant way the sexual performance, the personal satisfaction, the commitment with the partner and their self-esteem. The health personnel who care for these patients must be updated about their causes, current treatments, new approaches that deepen its etiology, evolution, implications and association with other diseases. Therefore, improving the prevention, treatment and rehabilitation of alterations in sexual response and especially erectile dysfunction is a goal to be achieved, which presupposes knowledge and awareness of all professionals and health decision makers.

    Conclusions: Complete (severe and partial erectile dysfunction was quite common among adult diabetic patients in a hospital-based primary care setting in Saudi Arabia. It is important for primary care physicians to diagnose erectile dysfunction in diabetic patients, and to counsel them early, as most patients are hesitant to discuss their concern during a consultation. Further studies are recommended to evaluate the effect of other risk factors on erectile dysfunction in diabetic patients.

    Sexual dysfunction is an important public health problem in men and is associated with reduced quality of life. It is more common in patients with schizophrenia. It is well-established that antipsychotic drugs cause sexual dysfunction with consequences on the quality of life of patients, adherence to treatment, and public health costs. Phosphodiesterase type 5 inhibitors (PDE5 inhibitors) are indicated for the management of erectile dysfunction. However, there is little information on such treatment in schizophrenic patients. This literature review aimed to summarize the current data on the efficacy and tolerability of PDE-5 inhibitors in the erectile dysfunction in schizophrenic patients. PubMed, PsycInfo and Cochrane databases were searched for studies published until August 2014. Only 6 studies met the inclusion criteria. Three were randomized, double-blind, cross-over, placebo-controlled trials and three were open studies. Various scales were used to measure erectile and orgasmic function, desire, satisfaction during intercourse, overall satisfaction, quality of life and intensity of schizophrenic symptoms. In the 3 randomized studies (one with sildenafil 25-50 mg, one with lodenafil carbonate 80 mg/j and the last one with tadalafil 10 mg), the rate of participants who completed the trial was high (around 95 %). All three included patients with schizophrenia or schizophrenia spectrum disorders. Patients reported significant improvement on sexual dysfunction. However, no statistical difference was reported between lodenafil and placebo, on different scales, suggesting a very important placebo effect in patients with schizophrenia. All three found a good tolerance of PDE-5 inhibitors. Side effects were rare and were mainly nasal congestion, headaches, nausea and dizziness. There were no major side effects or drug interactions. Considering the 3 open studies, 2 involved sildenafil and one tadalafil. All concluded in improved erectile and orgasmic

    To investigate the possible role of fesoterodine (a competitive muscarinic receptor antagonist) on erectile dysfunction in streptozotocin-induced diabetic rats. A total of 16 adult male Sprague-Dawley rats were equally divided into control and diabetic groups. Diabetes was induced by a single intravenous injection of streptozotocin (25-35 mg/kg). In vivo erectile responses were evaluated by the stimulation of cavernosal nerves, and measurements were repeated after the intracavernosal injection of fesoterodine (1 µM) in rats. The relaxation responses to fesoterodine were examined via incubation with various inhibitors. The relaxant responses of corpus cavernosum (CC) strips were observed in the presence or the absence of fesoterodine (10 µM). Intracavernous administration of fesoterodine restored in vivo erectile response at 5.0- and 7.5-V levels, except for 2.5 V in diabetic rats. Basal intracavernosal pressure (5.4 ± 0.9 mm Hg) in diabetic rats was markedly increased after injection of fesoterodine (33.9 ± 7.9 mm Hg, P <.001). In bath studies, fesoterodine resulted in a relaxation of CC in a concentration-dependent manner, which was reduced in diabetic rats. Nifedipine (l-type Ca 2+ channel blocker) inhibited maximum fesoterodine-induced relaxation by 58%. The nonselective K + channel blocker tetraethylammonium and glibenclamide incubation did not change the relaxant response to fesoterodine. The relaxant responses to acetylcholine (10 µM), electrical field stimulation (10 Hz), and sodium nitroprusside (0.01 µM) in diabetic rats were increased after incubation with fesoterodine (10 µM). Fesoterodine improved erectile function and relaxation of isolated strips of rat CC. The underlying mechanism of fesoterodine is likely due to the blocking of l-type calcium channels independent of the nitric oxide-cyclic guanosine monophosphate pathway. Further investigations are warranted to fully elucidate the restorative effects of

    Hydrogen sulfide (H2S) is an endogenous gasotransmitter. The levels of H2S-generating enzyme expression and endogenous H2S production in diabetic rats with erectile dysfunction (ED) remain unknown. The aim of this study was to investigate the expression of the H2S-generating enzymes and endogenous production of H2S in penile tissues of diabetic ED rats. Experimental rats were randomly divided into normal control group, apomorphine (APO)-positive group and APO-negative group. Primary rat corpus cavernosum smooth muscle cells (CCSMCs) and aortic endothelial cells (AECs) were isolated and cultured in vitro under 3 different conditions: normal glucose (NG) condition, high glucose (HG) condition, and osmotic control (OC) condition. Erectile function; H2S concentrations in plasma or penile tissues; expression of H2S-generating enzymes and endogenous H2S production in penile tissues, CCSMCs, and AECs. Erectile function was significantly decreasedin the APO-negative group. In addition to significantly decreased expression of cysteine aminotransferase (CAT), d-amino acid oxidase (DAO), and 3-mercaptopyruvate sulfurtransferase (3-MST), the H2S concentrations in plasma and penile tissues and endogenous H2S production were significantly decreased in the APO-negative group. Endogenous H2S production by cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) decreased to the same levels in the APO-negative and APO-positive groups as that in the normal control group. However, CBS and CSE expression remained unchanged in the 3 groups. Under HG conditions, H2S-generating enzyme expression in AECs did not change, while CAT, DAO, and 3-MST expression in CCSMCs was significantly decreased. In both cell types, H2S production by these enzymes was decreased in the HG group. Endogenous H2S production was significantly decreased in the diabetic ED rats' penile tissues due to downregulated expression of the CAT/3-MST and DAO/3-MST pathways and low activities of CBS and CSE

    Full Text Available Stem cell therapy is a novel method for the treatment of diabetic erectile dysfunction (ED. Many relative animal studies have been done to evaluate the efficacy of this therapy in rats.This meta-analysis was performed to compare the efficacy of different stem cell therapies, to evaluate the influential factors and to determine the optimal stem cell therapeutic strategy for diabetic ED.We searched the studies analyzing the efficacy of stem cell therapy for diabetic ED in rats published before September 30, 2015 in PubMed, Web of Science and EBSCO. A random effects meta-analysis was conducted to assess the outcomes of stem cell therapy. Subgroup analysis was also performed by separating these studies based on their different characteristics. Changes in the ratio of intracavernous pressure (ICP to mean arterial pressure (MAP and in the structure of the cavernous body were compared.10 studies with 302 rats were enrolled in this meta-analysis. Pooled analysis of these studies showed a beneficial effect of stem cell therapy in improving erectile function of diabetic rats (SMD 4.03, 95% CI = 3.22 to 4.84, P< 0.001. In the stem cell therapy group, both the smooth muscle and endothelium content were much more than those in control group. There was also significant increase in the expression of endothelial nitric oxide synthase (eNOS and neuronal nitric oxide synthase (nNOS, the ratio of smooth muscle to collagen, as well as the secretion of vascular endothelial growth factor (VEGF. Besides, apoptotic cells were reduced by stem cell treatment. The subgroup analysis indicated that modified stem cells were more effective than those without modification.Our results confirmed that stem cell therapy could apparently improve the erectile function of diabetic rats. Some specific modification, especially the gene modification with growth factors, could improve the efficacy of stem cell therapy. Stem cell therapy has potential to be an effective therapeutic

    Erectile dysfunction (ED) is a frequent complaint of elderly subjects and is closely associated with endothelial dysfunction and cardiovascular disease (CVD). Uric acid is also associated with endothelial dysfunction, oxidative stress, and CVD, raising the hypothesis that an increased serum uric acid might predict ED in patients who are at risk for coronary artery disease (CAD). This study aims to evaluate the association of serum uric acid levels with presence and severity of ED in patients presenting with chest pain of presumed cardiac origin. This is a cross-sectional study of 312 adult male patients with suspected CAD who underwent exercise stress test (EST) for workup of chest pain and completed a sexual health inventory for men survey form to determine the presence and severity of ED. Routine serum biochemistry (and uric acid levels) were measured. Logistic regression analysis was used to assess risk factors for ED. The short version of the International Index of Erectile Function questionnaire diagnosed ED (cutoff score ≤ 21). Serum uric acid levels were determined. Patients with chest pain of suspected cardiac origin underwent an EST. One hundred forty-nine of 312 (47.7%) male subjects had ED by survey criteria. Patients with ED were older and had more frequent CAD, hypertension, diabetes and impaired renal function, and also had significantly higher levels of uric acid, fibrinogen, glucose, C-reactive protein, triglycerides compared with patients without ED. Uric acid levels were associated with ED by univariate analysis (odds ratio = 1.36, P = 0.002); however, this association was not observed in multivariate analysis adjusted for estimated glomerular filtration rate. Subjects presenting with chest pain of presumed cardiac origin are more likely to have ED if they have elevated uric acid levels. © 2013 International Society for Sexual Medicine.

    Full Text Available Background: Depression imposes numerous changes on depressive men, promoting for low bone mineral density (BMD and erectile dysfunction (ED, yet no published data on exploring the possible association between these two disorders among depressive men. We therefore investigated whether low BMD is associated with ED among depressive men and highlighted the possible mutual underlying factors that might give rise to these two disorders in this specific group of patients. Materials and Methods: In this cross-sectional study, 119 depressive men were recruited and their sociodemographic and clinical characteristics were obtained. Erectile function was evaluated using the 5-item International Index of Erectile Function. All patients received a calcaneal BMD scanning. Chi-square test was conducted to determine if a significant association exists between ED and low BMD. Results: Of the study participants, ninety patients reported ED, while 29 patients reported no ED. Within the ED group, there was a significantly higher proportion of patients with low BMD compared to the non-ED group (85.6% vs. 62.1%, P = 0.006. In addition, among younger participants (i.e., aged < 50 years old, the difference in T-score between ED patients (Md = −2.2, n = 41 and non-ED patients (Md = −1.3, n = 20 was significant (P = 0.001; but held no significance among older participants. Conclusions: While our findings are considered prefatory, we reported that low BMD was significantly associated with ED in depressive men and that only among young depressive patients, BMD was significantly lower in ED patients compared to non-ED patients. More research investigating these findings and the possible underlying mechanisms for such association are warranted.

    We have recently reported that the perceived loss of a partner's sexual desire is independently associated with an increased incidence of major cardiovascular events in patients with erectile dysfunction (ED). No study has ever evaluated the specific impact of men's perception of women's sexual desire on male sexual function and lifestyle attitudes in ED subjects. To evaluate the clinical correlates of the perception of a partner's sexual desire [hypoactive sexual desire (HSD)] in a consecutive series of subjects seeking medical care for ED. A consecutive series of 2,303 heterosexual male patients (mean age 58.1 ± 10.5) was studied. Patients were interviewed with the Structured Interview on Erectile Dysfunction (SIEDY) structured interview. They also completed the Middlesex Hospital Questionnaire, a brief questionnaire for the screening of the symptoms of mental disorders. Among the patients studied, 458 (19.9%) reported a mild loss of their partner's desire, 302 (13.1%) a moderate reduction of libido, while 118 (5.1%) complained of a complete absence of sexual interest on the part of their partner. After adjustment for confounding factors, the perceived women's HSD was associated with different sexual, lifestyle, and relational factors. In particular, more extra-marital affairs, a longer and more hostile couple relationship, as well as a stressful job and both alcohol and smoking abuse were all significantly associated with perceived women's HSD. In addition, the perceived women's moderate to severe HSD was significantly associated with severe ED and less frequent sexual intercourse. Finally, partner HSD was significantly associated with a stepwise increase of free-floating anxiety and depressive symptoms (adj. r = 0.081, P < 0.05 and 0.158, P < 0.0001, respectively). Perceived sexual interest (éros) on the part of the woman can be seen for men not only as a fun and enjoyable behavior, but also a safe strategy for improving a man's overall health and life

    Purpose/Objectives: Erectile dysfunction is common after radiation therapy for prostate cancer; yet, the etiopathology of radiation-induced erectile dysfunction (RI-ED) remains poorly understood. A novel animal model was developed to study RI-ED, wherein stereotactic body radiation therapy (SBRT) was used to irradiate the prostate, neurovascular bundles (NVB), and penile bulb (PB) of dogs. The purpose was to describe vascular and neurogenic injuries after the irradiation of only the NVB or the PB, and after irradiation of all 3 sites (prostate, NVB, and PB) with varying doses of radiation. Methods and Materials: Dogs were treated with 50, 40, or 30 Gy to the prostate, NVB, and PB, or 50 Gy to either the NVB or the PB, by 5-fraction SBRT. Electrophysiologic studies of the pudendal nerve and bulbospongiosus muscles and ultrasound studies of pelvic perfusion were performed before and after SBRT. The results of these bioassays were correlated with histopathologic changes. Results: SBRT caused slowing of the systolic rise time, which corresponded to decreased arterial patency. Alterations in the response of the internal pudendal artery to vasoactive drugs were observed, wherein SBRT caused a paradoxical response to papaverine, slowing the systolic rise time after 40 and 50 Gy; these changes appeared to have some dose dependency. The neurofilament content of penile nerves was also decreased at high doses and was more profound when the PB was irradiated than when the NVB was irradiated. These findings are coincident with slowing of motor nerve conduction velocities in the pudendal nerve after SBRT. Conclusions: This is the first report in which prostatic irradiation was shown to cause morphologic arterial damage that was coincident with altered internal pudendal arterial tone, and in which decreased motor function in the pudendal nerve was attributed to axonal degeneration and loss. Further investigation of the role played by damage to these structures in RI-ED is

    Erectile dysfunction (ED) is a common complication of diabetes. Endothelial cell (EC) dysfunction is one of the main mechanisms of diabetic ED. However, loss of EC integrity has never been assessed in human diabetic corpus cavernosum. To identify and quantify apoptotic cells in human diabetic and normal erectile tissue and to compare these results with each patient's clinical data and erection status. Eighteen cavernosal samples were collected, 13 from diabetics with ED and 5 from nondiabetic individuals. Cavernosal structure and cell proliferation status were evaluated by immunohistochemistry. Tissue integrity was assessed by terminal transferase dUTP nick end labeling assay, an index of apoptotic cell density (ACD) established and compared with each patient age, type of diabetes, arterial risk factors number, arterial/veno-occlusive disease, response to intracavernous vasoactive injections (ICI), and penile nitric oxide release test (PNORT). Establish an index of ACD and correlate those results with patient clinical data. Nondiabetic samples presented few scattered cells in apoptosis and an ACD of 7.15 +/- 0.44 (mean apoptotic cells/tissue area mm(2) +/- standard error). The diabetic group showed an increased ACD of 23.82 +/- 1.53, and apoptotic cells were located specifically at vascular sites. Rehabilitation of these endothelial lesions seemed impaired, as no evidence of EC proliferation was observed. Furthermore, higher ACD in diabetic individuals correlated to poor response to PNORT and to ICI. We provided evidence for the first time that loss of cavernosal EC integrity is a crucial event involved in diabetic ED. Furthermore, we were able to establish a threshold between ACD values and cavernosal tissue functionality, as assessed by PNORT and vasoactive ICI.

    Background The penile erectile tissue has a complex microscopic anatomy with important functions in the mechanism of penile erection. The knowledge of such structures is necessary for understanding the normal physiology of the adult penis. Therefore, it is important to know the changes of these penile structures during fetal development. This study aims to analyze the development of the main components of the erectile tissue, such as collagen, smooth muscle fibers and elastic system fibers, in human fetuses. Methodology/Principal Findings We studied the penises of 56 human fetuses aged 13 to 36 weeks post-conception (WPC). We used histochemical and immunohistochemical staining, as well as morphometric techniques to analyze the collagen, smooth muscle fibers and elastic system fibers in the corpus cavernosum and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image J software (NIH, Bethesda, USA). From 13 to 36 WPC, in the corpus cavernosum, the amount of collagen, smooth muscle fibers and elastic system fibers varied from 19.88% to 36.60%, from 4.39% to 29.76% and from 1.91% to 8.92%, respectively. In the corpus spongiosum, the amount of collagen, smooth muscle fibers and elastic system fibers varied from 34.65% to 45.89%, from 0.60% to 11.90% and from 3.22% to 11.93%, respectively. Conclusions We found strong correlation between the elements analyzed with fetal age, both in corpus cavernosum and corpus spongiosum. The growth rate of these elements was more intense during the second trimester (13 to 24 WPC) of gestation, both in corpus cavernosum and in corpus spongiosum. There is greater proportional amount of collagen in the corpus spongiosum than in corpus cavernosum during all fetal period. In the corpus spongiosum, there is about four times more collagen than smooth muscle fibers and elastic system fibers, during all fetal period studied. PMID:25170760

    Full Text Available Purpose: We aimed to assess whether nerve-sparing radical prostatectomy (nsRP is associated with improved recovery of urinary continence compared to non–nerve-sparing radical prostatectomy (nnsRP in patients with localized prostate cancer and preoperative erectile dysfunction. Methods: A total of 360 patients with organ-confined prostate cancer and an International Index of Erectile Function score of less than 17 were treated with nsRP or nnsRP in Seoul St. Mary’s Hospital. Patients who received neoadjuvant or adjuvant androgen deprivation therapy or had a history of prostate-related surgery were excluded. Recovery of urinary continence was assessed at 0, 1, 3, 6, and 12 months. Postoperative recovery of continence was defined as zero pad usage. The association between nerve-sparing status and urinary continence was assessed by using univariate and multivariate Cox regression analyses after controlling for known predictive factors. Results: Urinary continence recovered in 279 patients (77.5% within the mean follow-up period of 22.5 months (range, 6–123 months. Recovery of urinary continence was reported in 74.6% and 86.4% of patients after nnsRP and nsRP, respectively, at 12 months (P=0.022. All groups had comparable perioperative criteria and had no significant preoperative morbidities. Age, American Society of Anesthesiologists score, and nerve-sparing status were significantly associated with recovery of urinary continence on univariate analysis. On multivariate analysis, age (hazard ratio [HR], 1.254; 95% confidence interval [CI], 1.002–1.478; P=0.026 and nerve-sparing status (HR, 0.713; 95% CI, 0.548–0.929; P=0.012 were independently associated with recovery of urinary continence. Conclusions: nsRP, as compared to nnsRP, improves recovery rates of urinary incontinence and decreases surgical morbidity without compromising pathologic outcomes.

    A number of disease processes of the penis including Peyronie's disease, priapism, penile fractures and tumors are clearly visualized with ultrasound. Diagnostic evaluation of erectile dysfunction (ED) by penile dynamic colour-duplex Doppler ultrasonography (D-CDDU) is actually considered a second level approach to ED patients because of the fact that intracavernous injections test IV with prostaglandin-E(1) may provide important information about the patients' erectile capacity. However, no direct vascular imaging and a high percentage of false negative diagnoses of vasculogenic ED are its major pitfalls and subsequent treatment decisions remain quite limited. The occurrence of ED and its sentinel relationship to cardiovascular disease has prompted more accurate vascular screening in all patients even in the absence of cardiovascular risk factors. The sonographic evaluation of the intima-media thickness of the carotid arteries may sometimes represent an early manifestation of diffuse atherosclerotic disease and endothelial damage. This latter finding is often the cause of failure to oral agents, i.e. phosphodiesterase inhibitors, because of inability of the dysfunctional endothelium to release nitric oxide. D-CDDU represents an accurate tool to investigate cavernous artery inflow and venous leakage when compared with more invasive diagnostic techniques i.e. selective arteriography and dynamic infusion cavernosometry along with cavernosography.

    A limited number of studies have reported an association between erectile dysfunction (ED) and chronic periodontitis (CP). The aim of the present study is to assess the association between CP and ED through a systematic review of published literature. To address the focused question, "Is there a relationship between ED and CP?" indexed databases were searched till December 2015 using various key words "erectile dysfunction," "periodontal disease," "periodontitis," "dental infection," and "impotence." Letters to the editor, commentaries, historic reviews, and experimental studies were excluded. The pattern of the present systematic review was customized to primarily summarize the pertinent data. Nine studies were included. Seven studies had a cross-sectional design and two studies were randomized control trials. The number of study participants ranged between 53 and 513,258 individuals with age ranging between 20 years and 85 years (median age ranging between 34.9 ± 4.9 years and 50.9 ± 16.6 years). In all studies, a positive relationship between CP and ED was reported. In four studies, odds ratio were reported, ranging between 1.53 and 3.35. From the literature reviewed, there seems to be a positive association between ED and CP; however, further well-designed controlled clinical trials are needed in this regard. It is emphasized that physicians should refer patients with ED to oral health care providers for a comprehensive oral evaluation and treatment.

    Erectile dysfunction adversely affects the lives of millions of men, and is the most commonly treated sexual disorder today. The erectile process has been extensively investigated, with major advances made in elucidating many of the complex molecular pathways involved. These advances have allowed researchers to design and study drug formulations that target various aspects of this complex process. The initial culmination of this research was the introduction of phosphodiesterase 5-inhibitors. While effective in many patients, they are not satisfactory for all afflicted men. As a result, researchers are developing novel drugs that target different molecular pathways. The paper will review these pathways, and the potential agents that target them. More specifically, first dopaminergic and melanocortin receptor agonists that act centrally will be covered. Then, the paper will examine the "second-generation" phosphodiesterase 5-inhibitors, soluble guanylate cyclases, rho-kinase inhibitors, and maxi-k channel activators that act peripherally. Most of these novel drugs have yet to reach Phase III studies. However, it is likely that in years to come, patients will be selectively treated with these novel agents as a monotherapy or in combination with others acting in a synergistic manner.

    We evaluated chemical and physical environmental agents as risk factors for erectile dysfunction among a consulting population. We studied 199 men who sought medical help for erectile disorders between 1996 and 1998 in 3 andrology units in the Litoral Sur region of Argentina. Patients were evaluated by monitoring nocturnal penile tumescence and rigidity, and were classified as having normal (n = 26), irregular (dissociation, short episode or low amplitude, n = 146), or flat erectile pattern (n = 26). Exposure to environmental agents was assessed by a detailed interview, and 4 groups were constituted: nonexposed, pesticide-exposed, solvent-exposed, and heat-exposed. A multivariate polytomous logistic regression model was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for association between quality of nocturnal erections and exposure groups adjusted for confounding factors. Exposure to environmental agents was a risk factor for a flat erectile pattern (OR 7.1, 95% CI 1.5-33.0 for pesticides; OR 12.2, 95% CI 1.2-124.8 for solvents; and OR 1.7, 95% CI 0.3-9.4 for heat). Associations were much weaker for an irregular erectile pattern (OR 1.8, 95% CI 0.5-6.7 for pesticides; OR 2.1, 95% CI 0.3-17.9 for solvents; and OR 1.2, 95% CI 0.4-4.0 for heat). Our results suggest that environmental agents constitute a risk factor for erectile dysfunction by interfering with erectile ability.

    The objective of the study was to apply an illness representations framework to examine patients' beliefs about erectile dysfunction (ED) and the association between those beliefs and reported quality of life. A total of 41 patients attending two secondary care clinics at a teaching hospital completed questionnaires examining quality of life, sexual functioning, illness representations (cause, time-line, coherence, consequences, cure, control and emotion) and perceptions of masculinity. Masculinity, sexual function, emotions and beliefs about consequences were found to be significantly correlated with quality of life. Multiple regression analysis revealed a model that accounted for almost 35% of the variance in quality of life of ED patients. The strongest predictor of higher quality of life was better sexual functioning (beta = -0.342, P < 0.05) followed by more positive beliefs about the effects of ED on masculinity (beta = 0.323, P < 0.05). The results suggest that when assessing the quality of life of men with ED, patients' illness representations should be considered along with their level of sexual functioning and the effects of ED on masculinity. Patients may benefit from an intervention programme that includes an educational component, thereby providing patients with more information about treatment options and available support.

    The disorders of the erectile dysfunction are well-known complication connected with the operating interventions of abdominal and pelvic surgery. Radical treatment of the malignancy, vascular operations and transurethral resection can lead to the rise of these disorders. The majority of these interventions is carried out at patients in the old age at which the disorders of the erection already existed about the various degree of intensification before treating operating how also the presence of the illnesses of the leaders to their rise or intensification after finishing the treatment (diabetes, arterial hypertension, arteriosclerosis). Patients in the young aged wait not only curing from the malignancy from second side, but also the behaviour of the quality of the life (QOL - quality of life), which the correct erection enabling is one of elements satisfying living together.

  5. The Role of Oxygen Tension in Penile Erection and Its Relationship to Erectile Dysfunction

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available The corpus cavernosum of the penis is one of the few vascular beds in which there is a change in oxygen tension with function (blood PO2 25-40mm Hg in the flaccid state, and 90-100mm Hg in the erect state. This change in oxygen tension exposes the components of the corpus cavernosum to a variety of cytokines, humoral, vasoactive, and growth factors which may affect the structure and function of the endothelial cells, smooth muscle cells, neurons and extracellular matrix. Among these cell types, endothelial cells are the first line of defense to blood-borne stress and can affect the underlying smooth muscle via paracrine mechanisms. Impotence is defined as the inability to obtain or sustain an erection sufficient for vaginal penetration and can result from a variety of pathological conditions, vascular disease, endocrine disease, neurological disease, and psychogenic disorders. The penis is a vascular organ and as such is susceptible to the effects of vascular diseases. This review will discuss the basic etiology of erection and vasculogenic erectile dysfunction and explore the role oxygen tension in regulating various cellular and humoral factors as well as trabecular structure and function.

    Areca nut chewing has been shown to increase the risk of cardiovascular disease, but its association with erectile dysfunction (ED) has not been investigated. To investigate the association between areca nut chewing and risk of ED. Consecutive men at public health centers for oral malignancy screening or health checkup were invited to complete a questionnaire. The Sexual Health Inventory for Men (SHIM). Of the 2,652 respondents, 1,038 (mean age = 43.8 ± 11.1 years) were eligible for the areca nut chewing group and 1,090 non-areca nut chewers were selected as the age-matched control group. In the areca nut group, the mean duration of chewing was 13.2 ± 9.6 years, 61.7% consumed more than 10 portions per day, and 76.2% used it with betel leaf, 16.7% used it with betel inflorescence, and 7.1% used it with betel leaf and inflorescence. Smoking, alcohol drinking, obesity, hypertension, and diabetes were more predominant in areca nut chewers compared with controls. ED defined by self-report and by SHIM score was more prevalent in areca nut chewers than in controls (13.7% vs 9.8% and 48.7% vs 43.3%, respectively; P betel inflorescence was associated with a higher risk of ED (odds ratio = 2.25, 95% confidence interval = 1.55-3.28) with a dose-dependent effect, whereas using it with betel leaf was not (odds ratio = 1.00, 95% confidence interval = 0.79-1.26) after adjustment of possible confounders. Areca nut chewing with betel inflorescence was associated with an increased risk of ED. These findings warrant further studies. Huang Y-J, Jiann B-P.

    Relatively few studies have addressed the risk factors of erectile dysfunction (ED) in Taiwanese- most have described ED and medical problems in the general population. In this study, the cardiovascular risk factors of ED among aborigines in Taiwan were investigated. However, alcohol dependence (AD) was prevalent in Taiwan's aborigine population. So this study also focused on the relationship among AD, the cardiovascular risk factors and ED. A cross-sectional study was conducted, and data was obtained from a baseline survey of 192 aboriginal adults (35-75 years of age). The participants' demographic data, AD, markers of endothelial function, serum testosterone, and ED status were assessed. Ninety-four (49%) of the 192 participants had a history of alcoholism and 79 (84%) of those with alcoholism had ED. The study reported that AD and hyperlipidemia, metabolic syndrome (MetS), ED, abnormality of testosterone, and high-sensitivity C-reactive protein are highly prevalent among the aborigines. Factors that may affect ED included age, AD, central obesity, diabetes mellitus, hyperlipidemia, hypertension, MetS, and testosterone. ED is highly prevalent among aborigines with the risk factors of AD, MetS, old age, and abnormal testosterone serum level. MetS, atherosclerosis, and ED are risk factors for cardiovascular diseases. Hence, an increased focus on Taiwanese aborigines with ED is necessary. © The Author(s) 2014.

    2018-05-01

    Full Text Available Purpose: We investigated the correlations of serum total testosterone (TT levels with body composition and physical fitness parameters in patients with erectile dysfunction (ED to know the best exercise for testosterone deficiency. Materials and Methods: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly correlated with serum TT levels. Results: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation with serum TT levels. Conclusions: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory fitness via aerobic exercise.

    Introduction: Erectile dysfunction (ED) is related to chronic diseases, including COPD. The patho- genesis may involve chronic hypoxia, which is common in interstitial lung disease (ILD). We aimed to study the relationship between ILD and ED. Method: Male patients with ILD detected by high...... degree of ED, thirty (56.6%) had moderate to severe ED, and 23 (43.4%) had severe ED. Low diffusion capacity and high body mass index showed a trend of increasing risk of moderate to severe ED. The risk increased with age (OR per 5-year increase=2.63 (1.25; 5.53)) and decreased with 6MWT distance (OR per...... 50 m increase=0.60 (0.41; 0.89). Only two patients (6.7%) received specific treatment with phosphodiesterase-5 inhibitors. Conclusion: Severe ED is a common problem in men with ILD, and is associated with poor walking distance and high age. Treatment coverage is low, and physicians should ad- dress...

    Phosphodiesterase 5 (PDE5) inhibitors are recommended as first line therapy for the treatment of erectile dysfunction (ED). To date, three PDE5 inhibitors are on the market: sildenafil, vardenafil and tadalafil. These compounds are available as oral tablets; they are rapidly absorbed in the gastrointestinal tract and are excreted mainly in the fces and to a lexer extent in the urine. Recently, an orodisnersible formulation of feces and, to a lesser extent, in the urine. Recently, an orodispersible formulation of vardenafil (vardenafil ODT) has been developed, which is able to dissolve in the mouth within seconds, releasing a minty flavor, without the need of being swallowed with water. The clinical studies so far performed showed that vardenafil ODT has a bioavailability superior to the traditional film-coated tablet. Among the other PDE5 inhibitors under development we report mirodenafil, lodenafil carbonate, avalafil and SLx-2101 It is likely that in the future molecules that act on pathways other than the one of NO/cGMP will be available. Such as Rho-kinase inhibitors, which inhibit the mechanism that leads to smooth muscle contraction thus allowing erection and hydrogen sulphide (H2S), an endogenous molecule synthesized from cysteine that can be both a vasodilator and a vasoconstrictor according to its concentration.

    Phosphodiesterase type 5 inhibitors (PDE5Is) are the leading drugs for the treatment of erectile dysfunction (ED), being recommended as a first line treatment by both the European and US urological guidelines. PDE5Is are highly effective as compared to placebo, well tolerated and have a very low, though not negligible, rate of severe treatment-related adverse events. This paper reviews the safety profile of currently available PDE5Is, comparing them in a broad spectrum ED population and outlining a number of real-life aspects of importance in the real-life everyday clinical setting. Guidelines unanimously agree in considering PDE5Is as first line treatments for ED when well-tolerated and not contraindicated. Despite the fact that no high-grade evidence comparing the efficacy and the safety for PDE5Is is currently available, published data seem to suggest that there are no major differences in their safety profiles. Moreover, although oral PDE5Is were shown to cause more AEs than placebo, they were generally mild and well tolerated.

    Objective: To understand the current situation and trend on the relations between erectile dysfunction (ED) and cardiovascular disease (CVD) through analyzing the epidemiologic research data. Methods: We conducted a literature search on the Scopus for potentially relevant epidemiologic studies on ED and CVD published from 1957 to October, 28, 2016. Age of the article, types, regions, citation, and co-authorship of the documents were recorded. Results: A total number of 412 pieces of literature were published in the past six decades, with original articles the most common types of ED and CVD. ED and CVD associated epidemiologic topics had an annual increase in number, and remained stable in the past decade, with occident countries as the United States and Italy taking the lead in this area. Clinical and epidemiological studies were the hottest areas, with most authors sharing a co-authorship. Conclusion: Our results suggested that inter-disciplinary cooperation with emphasize on clinical application were the effective starting points for ED and CVD associated epidemiologic studies.

    To investigate the relationship between variations of the pelvic artery arrangement and the age at erectile dysfunction (ED) onset, as some men develop ED while relatively young, while others maintain erectile function into old age despite having cardiovascular diseases, thus congenital factors might be involved. We examined 290 units of internal iliac arteries (IIA) in 145 patients showing repeated incomplete erectile response to intracavernosal injections with prostaglandin E(1). Patients with cardiovascular risk factors, neurological disease or pelvic injury were excluded. The pelvic artery arrangement, evaluated by three-dimensional computed tomographic angiography, was classified anatomically into five types: Type 1 (normal or basic type), in which the internal pudendal artery (IPA) originates from the anterior trunk at the level between the linea terminalis and the major ischial notch; Type 2, the IPA originates from the anterior trunk of the IIA at the level of the major ischial notch or more distally; Type 3, the IPA originates directly from the IIA at a level proximal to the linea terminalis; Type 4, the IPA originates together with the superior and inferior gluteal artery within 1 cm of each other; and Type 5, the penile blood supply is dependent on arteries other than the IPA, such as the obturator artery. Among the 290 units, eight could not be classified due to poor image quality. There were no statistically significant differences in blood flow parameters among the types of IIAs, but there was a statistically significant difference in the IPA type at the age of onset of ED. Type 1 (153 units or 53%) anatomy, was more common in patients who developed ED at an advanced age. Types 2, 3 and 4 were more common in patients with onset of ED at an early age (log-rank test P < 0.001, P = 0.044, P < 0.001, respectively). Compared with patients with the common type of IIAs bilaterally, patients with any of the variations bilaterally are at risk of early onset of

    Full Text Available Background. Male patients with end stage renal disease often report erectile dysfunction, which is very common especially in younger males. Impotence is reported to exceed 50% in male chronic renal failure patients, and is present in 65% of such patients undergoing hemodialysis. Numerous etiological factors have been reported as possible cause for sexual dysfunction. Sildenafil (Viagra®, a potent specific inhibitor of cGMP phosphodiesterase, was used in this case study to improve erectile dysfunction in dialysis male patients.Methods and results. During 12 weeks we treated 4 dialysis patients. 2 patients were treated with peritoneal dialysis and 2 patients were in the program of chronic hemodialysis. All patients were in the program of dialysis for more than 24 months, and reported erectile dysfunction and impotence after they had started with dialysis treatment. Sildenafil was used in the treatment. The dosage schedule for sildenafil was 50mg/ week orally for 2 weeks followed by 100 mg/week for the next 10 weeks if there was no effect on initial dosage. Efficacy of treatment was evaluated by means of the International Index of Erectile Dysfunction. All 4 patients reported no significant effect on initial dose. With higher dose of sildenafil treatment was overwhelmingly successful, with reported prolonged improvement of erectile dysfunction for 42 to 72 hours. Side effects were present only in 1 patient who had severe headaches after higher dose. No patients experienced priapism.Conclusions. There have been only few reports in the literature on the use of sildenafil in dialysis patients. Our small case study suggests that sildenafil could be successfully and safely used for treatment of erectile dysfunction also in dialysis patients. A large trial would be necessary to confirm the efficacy of the drug for this specific group of patients.

    Full Text Available Purpose The objective of this study is to investigate alteration of autonomic nervous system (ANS activity in patients suffering from erectile dysfunction (ED by comparing parameters of heart rate variability (HRV between men with ED and healthy subjects. Methods A retrospective review was performed on 40 ED patients (mean age, 46.0±8.49 years without any disease and 180 healthy control people (mean age, 44.4±7.83 years without ED in our institution from June 2008 to July 2010. And electrocardiographic signals were obtained to measure HRV parameters for both patients and controls in a resting state. Results For the time domain analysis, square root of the mean differences between successive RR intervals (RMSSD representing parasympathetic activity was lower in patients than controls although P-value was not statistically significant (P=0.060. For the frequency domain analysis, high frequency (HF representing parasympathetic activity was lower in patients than controls (P=0.232 and low frequency (LF representing mainly sympathetic activity was higher in patients than controls (P=0.416. Lastly, LF/HF ratio reflecting sympathetic/parasympathetic activity ratio was statistically higher in patients than controls (P=0.027. Conclusions Patients with ED exhibited different HRV parameters compared with normal controls. This suggests that the patients with ED may have some kind of imbalance in the ANS and it may be possible that general imbalance of the ANS is one of the causes of ED. Thus, HRV analysis may give valuable diagnostic information and serve as a rapid screening tool to evaluate altered ANS activity in patients with ED.

    In recent years, evidence has come forth supporting the notion that localized infectious diseases such as periodontal disease may indeed influence a number of systemic diseases. Erectile dysfunction (ED) and chronic periodontitis have common risk factors such as diabetes mellitus, cardiac diseases and smoking etc. The aim was to evaluate the periodontal status of the subjects suffering from ED and to find association between vasculogenic ED and chronic periodontitis, if any. A total of 53 subjects suffering from vasculogenic ED were enrolled for the study and were divided into three groups on the basis of severity of ED. The clinical (probing pocket depth) and radiographic parameters (alveolar bone loss) were recorded and periodontal status of three groups was evaluated, compared and an attempt was made to find an association between ED and chronic periodontitis. Karl Pearson's correlation was used to assess an association between the two conditions. One-way ANOVA and Scheffe's test were used to find the significant difference of chronic periodontitis with severity of ED. Karl Pearson's correlation was used to find an association between chronic periodontitis and ED. Statistically significant mean differences of 1.73 mm, 0.56 mm and 1.17 mm were recorded when comparison was made among Group I and III, Group I and II and Group II and III, respectively. Mean differences in bone loss among three groups were also statistically significant. Both the diseases were positively correlated to each other. It may be concluded that chronic periodontitis and ED are associated with each other. However, further large scale studies with confounder analysis and longitudinal follow-up are warranted to explore the link between these two diseases.

    2002-03-01

    Prostate cancer has become the most common nonskin malignant neoplasm in older men in Western countries. As treatment efficacy has improved, issues related to posttherapy quality of life and sexual functioning have become more important. We discuss the various methods used to evaluate erectile and sexual dysfunction and the definition of potency. The etiologies of erectile dysfunction after external beam radiotherapy and brachytherapy for prostate cancer are also reviewed. The literature is summarized, and comparative studies of radiation and surgery are surveyed briefly. Rates of erectile dysfunction vary from 6 to 84% after external beam radiotherapy and from 0 to 51% after brachytherapy. In most of the studies, the analysis is retrospective, the definition of erectile dysfunction is not clear, only one question about sexual functioning is asked, and nonvalidated instruments are used. The etiology of erectile dysfunction after radiation for prostate cancer is not completely understood. Because erectile function is only one component of sexual function, it is necessary to assess sexual desire, satisfaction, frequency of intercourse, and other such factors when evaluating the effects of therapy. Patients should be offered sexual counseling and informed about the availability of effective treatments for erectile dysfunction, such as sildenafil, intracavernosal injection, and vacuum devices.

    Cigarette smoking has been implicated in the pathophysiology of cardiovascular disease (CVD) and as a risk factor for erectile dysfunction (ED). However, various aspects of the associations between cigarette smoking, ED, and CVD need further elucidation. We explored the relationship between cigarette smoking, ED, and CVD using data from a population-based cross-sectional study of 1,580 participants. Postal questionnaires were sent to randomly selected age-stratified male population samples obtained from the Western Australia Electoral Roll. In addition to items covering sociodemographic and self-reported clinical information and smoking habits, the 5-item International Index of Erectile Function was used to assess erectile function. Compared with never smokers, the odds of ED, adjusted for age, square of age, and CVD, were significantly higher among current smokers (odds ratio [OR] = 1.40; 95% confidence interval [CI] 1.02, 1.92) and ever smokers (OR = 1.57; 95% CI 1.02, 2.42). Similarly, the adjusted odds of severe ED were significantly higher among former smokers. Albeit not statistically significant, the age-adjusted odds of ED among current smokers increased with the number of cigarettes smoked. Among former smokers, the age-adjusted odds of ED were significantly higher 6-10 years following cessation of smoking than 10 years. Compared with never smokers without CVD, the age-adjusted odds of ED among former smokers and ever smokers without CVD were about 1.6. Regardless of smoking, these odds were significantly higher among participants with CVD. Compared with never smokers, former smokers and ever smokers have significantly higher odds of ED. The relationship between smoking and ED is independent of that between smoking and CVD, and not because of confounding by CVD. Patterns of ED in former smokers suggest that there may be a latent interval between active smoking and symptomatic ED, involving a process initially triggered by smoking.

    Psychogenic erectile dysfunction (ED) is defined as a male sexual dysfunction characterized by a persistent or recurrent inability to attain adequate penile erection due predominantly or exclusively to psychological or interpersonal factors. Previous fMRI studies were based on the common occurrence in the male sexual behaviour represented by the sexual arousal and penile erection related to viewing of erotic movies. However, there is no experimental evidence of altered brain networks in psychogenic ED patients (EDp). Some studies showed that fMRI activity collected during non sexual movie viewing can be analyzed in a reliable manner with independent component analysis (ICA) and that the resulting brain networks are consistent with previous resting state neuroimaging studies. In the present study, we investigated the modification of the brain networks in EDp compared to healthy controls (HC), using whole-brain fMRI during free viewing of an erotic video clip. Sixteen EDp and nineteen HC were recruited after RigiScan evaluation, psychiatric, and general medical evaluations. The performed ICA showed that visual network (VN), default-mode network (DMN), fronto-parietal network (FPN) and salience network (SN) were spatially consistent across EDp and HC. However, between-group differences in functional connectivity were observed in the DMN and in the SN. In the DMN, EDp showed decreased connectivity values in the inferior parietal lobes, posterior cingulate cortex and medial prefrontal cortex, whereas in the SN decreased and increased connectivity was observed in the right insula and in the anterior cingulate cortex respectively. The decreased levels of intrinsic functional connectivity principally involved the subsystem of DMN relevant for the self relevant mental simulation that concerns remembering of past experiences, thinking to the future and conceiving the viewpoint of the other's actions. Moreover, the between group differences in the SN nodes suggested a

    Full Text Available To investigate the prevalence, correlates, attitude and treatment seeking behavior of erectile dysfunction (ED in type 2 diabetes mellitus (T2DM patients in the primary care setting, a multi-center cross-sectional survey using a structured anonymous self-administered questionnaire was performed in 10 general outpatient clinics. Of the 603 subjects (91% response rate, the prevalence of ED men, as defined by the International Index of Erectile Function, was 79.1%. Most subjects had mild ED (28.9%, followed by mild-to-moderate ED (27.9%, then moderate ED (13.4% and severe ED (9%. Nearly 55% of those with ED did not consider themselves as having ED. Less than 10% of them had ever sought medical treatment, although 76.1% of them wished to receive management from doctor(s should they be diagnosed with ED. They considered the most important management from doctors to be clinical assessment (41.7%, followed by management of potential underlying cause (37.8%, referral to specialist (27.5%, education (23.9%, prescription of phosphodiesterase type 5 inhibitors (16.9% and referral to counseling service (6.7%. The prevalence of ED was strongly associated with subjects who thought they had ED (odds ratio (OR = 90.49 (20.00-409.48, P< 0.001 and were from the older age group (OR = 1.043 (1.011-1.076, P= 0.008. In conclusion, ED is highly prevalent among T2DM men. The majority of them wanted management from doctors should they have ED, but only a minority would actually voice out the request. Screening of ED among T2DM men using structural questionnaire allowed the diagnosis of more than half of the ED cases, which otherwise would have gone undiagnosed.

    Neither men with erectile dysfunction (ED) nor their physicians are willing to discuss sexual problem sufficiently. Written information material could facilitate a dialogue and encourage men to seek treatment. The central task of this article was to determine the effectiveness and acceptance of patient information material for sexual dysfunction. Through an information campaign, men received informational material. Eight thousand men also received a first survey, which asked about the intention to seek treatment and to discuss the sexual problem with a physician or partner. A second follow-up questionnaire, 3-6 months after the first one, asked for the implementation of these intentions. Descriptive and regression-based analyses were applied. Help-seeking behavior, subjective assessment of change in disease severity and partnership quality, satisfaction. Four hundred forty-three men participated in both surveys. Nearly 90% of them became active after reading the information material. More than half talked with their partner (57.8%) and a physician (65%), and one-third sought treatment (31.8%). Especially discussing the problem with the partner and receiving treatment improved erectile functioning and led to an increase in the quality of partnership (P

    Full Text Available The aim of the present study was to examine whether hypoxia preconditioning could improve therapeutic effects of adipose derived mesenchymal stem cells (AMSCs for diabetes induced erectile dysfunction (DED. AMSCs were pretreated with normoxia (20% O2, N-AMSCs or sub-lethal hypoxia (1% O2, H-AMSCs. The hypoxia exposure up-regulated the expression of several angiogenesis and neuroprotection related cytokines in AMSCs, including vascular endothelial growth factor (VEGF and its receptor FIK-1, angiotensin (Ang-1, basic fibroblast growth factor (bFGF, brain-derived neurotrophic factor (BDNF, glial cell-derived neurotrophic factor (GDNF, stromal derived factor-1 (SDF-1 and its CXC chemokine receptor 4 (CXCR4. DED rats were induced via intraperitoneal injection of streptozotocin (60 mg/kg and were randomly divided into three groups-Saline group: intracavernous injection with phosphate buffer saline; N-AMSCs group: N-AMSCs injection; H-AMSCs group: H-AMSCs injection. Ten rats without any treatment were used as normal control. Four weeks after injection, the mean arterial pressure (MAP and intracavernosal pressure (ICP were measured. The contents of endothelial, smooth muscle, dorsal nerve in cavernoursal tissue were assessed. Compared with N-AMSCs and saline, intracavernosum injection of H-AMSCs significantly raised ICP and ICP/MAP (p<0.05. Immunofluorescent staining analysis demonstrated that improved erectile function by MSCs was significantly associated with increased expression of endothelial markers (CD31 and vWF (p<0.01 and smooth muscle markers (α-SMA (p<0.01. Meanwhile, the expression of nNOS was also significantly higher in rats receiving H-AMSCs injection than those receiving N-AMSCs or saline injection. The results suggested that hypoxic preconditioning of MSCs was an effective approach to enhance their therapeutic effect for DED, which may be due to their augmented angiogenesis and neuroprotection.

    Full Text Available Background: Neuroimaging studies have demonstrated that the prefrontal cortex and amygdala play an important role in sexual arousal (SA. However, little is known about the interactions between the prefrontal and cortex amygdala, which mediate the cognitive regulation of emotion and SA.Objective: We seek to determine whether nocturnal erection of psychogenic erectile dysfunction (pED patients are normal and whether there are changes of topological organization in the prefrontal-amygdala pathway of brain network in pED. In addition, whether there are correlations between network property changes and self-reported emotion and erection.Design, setting, and participants: We used the RigiScan device to evaluate erectile function of patients and employed diffusion MRI and graph theory to construct brain networks of 21 pED patients and 24 healthy controls.Outcome measurements and statistical analysis: We considered four nodal metrics and their asymmetry scores, and nocturnal penile tumescence (NPT parameters, to evaluate the topological properties of brain networks of pED and their relationships with the impaired self-reported emotion and erection.Results and limitations: All the pED patients showed normal nocturnal penile erection, however impaired self-reported erection and negative emotion. In addition, patients showed lower connectivity degree and strength in the left prefrontal-amygdala pathway. We also found that pED exhibited lower leftward asymmetry in the inferior frontal gyrus. Furthermore, patients showed more hub regions and fewer pivotal connections. Moreover, the degree of the left amygdala of pED showed significantly negative correlation with the self-reported erection and positive correlation with the self-reported negative emotion.Conclusions: Together, these results suggest normal nocturnal erection in pED. However, abnormalities of brain network organization in pED, particularly in the left prefrontal-amygdala pathway, are associated

Results and limitations: All the pED patients showed normal nocturnal penile erection, however impaired self-reported erection and negative emotion. In addition, patients showed lower connectivity degree and strength in the left prefrontal-amygdala pathway. We also found that pED exhibited lower leftward asymmetry in the inferior frontal gyrus. Furthermore, patients showed more hub regions and fewer pivotal connections. Moreover, the degree of the left amygdala of pED showed significantly negative correlation with the self-reported erection and positive correlation with the self-reported negative emotion. Conclusions: Together, these results suggest normal nocturnal erection in pED. However, abnormalities of brain network organization in pED, particularly in the left prefrontal-amygdala pathway, are associated with the

    Depression and erectile dysfunction (ED) often co-occur. Phosphodiesterase type 5 inhibitors are effective in men with ED and untreated depression, or ED secondary to antidepressants. This study evaluated sildenafil treatment in Canadian men with clinically diagnosed ED (Sexual Health Inventory for Men score ≤ 21) and mild-to-moderate untreated depressive symptoms [Beck Depression Inventory II (BDI-II) score 14-28], but excluding major depressive disorder. Pretreatment screening using the Sexual Health Inventory for Men and BDI-II showed that men with ED were more likely to have depression than men without ED, and ED severity was a predictor of depression (P=0.0226). Two hundred and two men were randomized to 6 weeks of double-blind treatment with placebo (n=98) or sildenafil (n=104), initial dose of 50 mg, adjustable to 25 or 100 mg. The men were evaluated on all domains of the International Index of Erectile Function and the Sex Effects Questionnaire, Global Efficacy Questions, and Event-log data. Compared with placebo, patients treated with sildenafil had significantly greater changes from baseline in BDI-II scores (P<0.001). All International Index of Erectile Function domains and the Sex Effects Questionnaire components were also significantly improved in sildenafil group (P<0.01). The most common adverse events included headache, dyspepsia, vasodilatation, and respiratory tract infections and were generally mild in intensity. 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.

    Studies evaluating the effect of education on treatment success with phosphodiesterase type 5 (PDE5) inhibitor therapy in men with erectile dysfunction (ED) are limited. Additional education of the primary care physician (PCP) and the patient are thought to optimize the treatment of ED. To assess the impact of education of the PCP or of the patient in the treatment of ED with vardenafil relative to usual care. In this 12-week, open-label, multicenter, factorial-designed, cluster-randomized Canadian study, 1,029 patients with ED were enrolled into four different education groups: usual care, patient education, PCP education, and both PCP and patient education. All groups started on vardenafil 10 mg, with the option to titrate at weeks 4 and 8. The primary efficacy measure was the difference at week 4 last observation carried forward (LOCF) in the overall improvement in erectile function (EF) as measured by the Global Assessment Question (GAQ), while on background vardenafil, between those receiving education vs. those who did not. Other secondary assessments included responses to diary questions regarding penetration (sexual encounter profile, SEP2) and erection maintenance (SEP3), and to questionnaires regarding treatment satisfaction (Erectile Dysfunction Inventory of Treatment Satisfaction [EDITS]). A total of 956 patients were included in the intent-to-treat population. Mean baseline International Index of Erectile Function-EF domain score was 13. GAQ response rates at week 4 LOCF were high (>80%) for all groups, regardless of the education given. Mean per patient SEP2 and SEP3 rates at week 12 LOCF were 86-89% and 79-83%, respectively. In an exploratory analysis, a positive relationship between GAQ responses and EDITS scores was observed (P satisfaction regardless of the education given. The benefits of education for PCP and patients in Canada were possibly masked by a ceiling effect in this study population.

    Full Text Available PURPOSE: To evaluate erectile function (EF and voiding function following primary targeted cryoablation of the prostate (TCAP for clinically localized prostate cancer (CaP in a contemporary cohort. MATERIALS AND METHODS: We retrospectively reviewed all patients treated between 2/2000-5/2006 with primary TCAP. Variables included age, Gleason sum, pre-TCAP prostate specific antigen (PSA, prostate volume, clinical stage, pre-TCAP hormonal ablation, pre-TCAP EF and American Urologic Association Symptom Score (AUASS. EF was recorded as follows: 1 = potent; 2 = sufficient for intercourse; 3 = partial/insufficient; 4 = minimal/insufficient; 5 = none. Voiding function was analyzed by comparing pre/post-TCAP AUASS. Statistical analysis utilized SAS software with p < 0.05 considered significant. RESULTS: After exclusions, 78 consecutive patients were analyzed with a mean age of 69.2 years and follow-up 39.8 months. Thirty-five (44.9% men reported pre-TCAP EF level of 1-2. Post-TCAP, 9 of 35 (25.7% regained EF of level 1-2 while 1 (2.9% achieved level 3 EF. Median pre-TCAP AUASS was 8.75 versus 7.50 postoperatively (p = 0.39. Six patients (7.7% experienced post-TCAP urinary incontinence. Lower pre-TCAP PSA (p = 0.008 and higher Gleason sum (p = 0.002 were associated with higher post-TCAP AUASS while prostate volume demonstrated a trend (p = 0.07. Post-TCAP EF and stable AUASS were not associated with increased disease-recurrence (p = 0.24 and p = 0.67, respectively. CONCLUSIONS: Stable voiding function was observed post-TCAP, with an overall incontinence rate of 7.7%. Further, though erectile dysfunction is common following TCAP, 25.7% of previously potent patients demonstrated erections suitable for intercourse. While long-term data is requisite, consideration should be made for prospective evaluation of penile rehabilitation following primary TCAP.

    Full Text Available This article presents a single-case study of a 22-year-old man with erectile dysfunction. The first assessment revealed problems within his relationship as the basis of the disorder. Systemic couple therapy sessions were conducted with both members in combination with several behavioural sex therapy techniques (sexual egoism, sensorial focusing, and instructions and exercises as homework. This mix of therapies had the goal of treating both the erectile disorder and the relationship to improve the sexual problem. A single-case design was used with the continuous assessment of sexual functioning through daily self-reports on sexual performance and satisfaction. Pre-post assessment was conducted with several specific questionnaires. The therapeutic process was completed in seven sessions over three months and in a follow-up session one year later. The results of questionnaires demonstrated the success of the treatment, which was maintained at follow-up. The data obtained from the continuous assessment also showed the progressive effect of the treatment. The clinical process ended with the complete remission of erectile dysfunction and the total satisfaction of the couple with their personal and sexual relationships.

    Research into sexual dysfunction and its explanations within a cognitive behavioral framework in patients with posttraumatic stress is sparse. In this report, we present the case of a 42-year-old male with severe posttraumatic stress symptoms who displayed apparent exhibitionistic behavior, hypersexual behavior in the form of excessive masturbation, and erectile dysfunction. Differential diagnostics showed that the presented exhibitionistic behavior could be more accurately classified as non-paraphilic disinhibited exposing behavior. Functional behavioral analysis of his sexual behavior suggested that disinhibited exposing and hypersexual behavior served as dysfunctional coping strategies for trauma-associated negative emotions. Erectile dysfunction seemed to be the result of trauma-associated hyperarousal and excessive masturbation. Within the context of operant learning processes, we propose that his sexual behaviors became highly automated and were used as the main strategies to regulate trauma-associated negative emotions. Implications for the diagnoses and suggestions for the conceptualization and incorporation into a cognitive behavioral therapy treatment of posttraumatic stress disorder are made.

    Before the 20th century, individuals often did not live beyond the reproductive years, and sexuality of the elderly was not an issue. However, in the current era it is known that as life expectancy improves, both men and women are seeking to preserve their sexuality into old age. While the appreciation of sexuality persists with aging, a decline in sexual activity is typically seen with, and can be attributed to both general health problems as well as specific sexual dysfunctions. Erectile dysfunction is the most frequently diagnosed sexual dysfunction in the older male population.

    The objective of this study was to explore the psychosocial meaning and repercussions on lifestyle associated with erectile dysfunction and urinary incontinence (UI) in men following radical prostatectomy. Ten men from Southeastern Brazil who underwent radical prostatectomy for prostate cancer were interviewed. All participants underwent treatment at a urology clinic during the period of September 2007 to February 2009. A clinical-qualitative study was conducted, using semi-structured interviews with open-ended questions. All interviews were recorded and transcribed verbatim. Each man was interviewed once. The average length of the interviews was 37 minutes (range: 16 to 81 minutes). Data from the interviews were subjected to content thematic analysis and development of categories based on psychodynamic references. Three themes were identified: (1) sexuality called into question; (2) a body without governance; and (3) experiencing loss. These men reported difficulties in dealing both with the physical and emotional impotence resulting from the treatment. Urinary incontinence and erectile dysfunction affected their body by accentuating conflicts related to masculinity, triggering subjective feelings of powerlessness, and psychological distress. Study respondents assigned multiple psychological meanings to issues related to feelings of powerlessness in general, leading to a narcissistic wound. The men experienced UI as a bodily deficiency, and erectile dysfunction was experienced as a feeling of being devitalized. These results suggest that UI from prostate cancer treatment affects sexuality and self-esteem.

    Recurrent (stuttering) ischemic priapism is a challenging clinical condition. Frequent recurrences result in frequent hospital admissions whereas treatment with a shunting procedure often results in erectile dysfunction. A 22-year-old man with stuttering idiopathic priapism developed erectile dysfunction (IIEF-5 score 12) following a Winter's shunt; he was given tadalafil, 5 mg/daily, for 6 months. This treatment resulted in progressive restoration of erectile function in the 6 months following the shunt as well as in preventing recurrence of priapic episodes over a 24-month follow-up. This is the first report in literature of chronic treatment of stuttering priapism with a phosphodiesterase-5 inhibitor being able not only to prevent recurrent priapic episodes but also to restore erectile function following a Winter's shunt.

    The aim of this study was to describe the prevalence of and risk factors for prostatitis-like symptoms and its relation to erectile dysfunction (ED) among southern Chinese men. Data were collected from 2790 men attending the Fangchenggang Area Male Healthy and Examination Survey from September 2009 to December 2009. The prostatitis-like symptoms were assessed by the NIH Chronic Prostatitis Symptom Index and ED was assessed using the 5-item International Index of Erectile Function. Lifestyle and demographic characteristics were obtained through a questionnaire. Prevalence of prostatitis-like symptoms was 12.4% among 2790 Chinese men aged 20-84 years. In smokers who smoked ≥20 cigarettes per day (age-adjusted OR = 1.29; 95% CI = 1.00-1.66; p = 0.04), physical inactivity (age-adjusted OR = 1.31; 95% CI = 1.03-1.66; p = 0.02) was a significant risk factor for prostatitis-like symptoms. Alcohol consumption (daily drinking) also was a risk factor for prostatitis-like symptoms, although the differences were not statistically significant (age-adjusted OR = 1.36; 95% CI = 0.96-1.92; p = 0.07). Those with diabetes may also be at higher risk for prostatitis-like symptoms (age-adjusted OR = 1.37; 95% CI = 0.85-2.21; p = 0.19). In addition, men with ED were more likely to have had prostatitis-like symptoms (age-adjusted OR = 1.86; 95% CI = 0.47-2.36; p prostatitis-like symptoms are prevalent in Southern China affecting men of all ages. Smoking, drinking, lack of physical activity, and elevated plasma glucose level were associated with an increased risk of prostatitis-like symptoms. In addition, our results reveal that ED accounted for a large proportion (61.5%) among men with prostatitis-like symptoms; we also confirm the magnitude of ED associated with prostatitis-like symptoms. Thus, interventions to evaluate and improve ED might help ameliorate prostatitis-like symptoms and vice versa. © 2015 American Society of Andrology and European Academy of Andrology.

    2012-01-01

    Surgical therapy remains the gold standard treatment for Peyronie's Disease (PD). Surgical options include plication, grafting, and placement of inflatable penile prosthesis (IPP). Postoperative erectile dysfunction (ED) is a potential complication for PD surgery without IPP. We present our large series follow-up to evaluate preoperative risk factors for postoperative ED. The aim of this study is to evaluate preoperative risk factors for the development of ED following surgical correction of PD taking into account the degree of curvature, graft size, surgical approach, hypertension, hyperlipidemia, diabetes, smoking history, preoperative use of phosphodiesterase 5 inhibitors (PDE5), and preoperative duplex ultrasound findings including peak systolic and end diastolic velocities and resistive index. We identified 218 men undergoing either tunica albuginea plication (TAP) or partial plaque excision with pericardial grafting for PD following a previously published algorithm between November 1992 and April 2007. Preoperative and postoperative erectile function, curvature characteristics, presence of vascular risk factors, and duplex ultrasound findings were available on 109 patients. Our primary outcome measure is the development of ED after surgery for PD. Ten percent of TAP and 21% of plaque excision with grafting patients developed postoperative ED. Neither curve direction (P = 0.76), graft area (P = 0.78), surgical approach (P = 0.12), chronic hypertension (P = 0.51), hyperlipidemia (P = 0.87), diabetes (P = 0.69), nor smoking history (P = 0.99) were significant predictors of postoperative ED. No combination of risk factors was found to be predictive of postoperative ED. Preoperative use of PDE5 was not a significant predictor of postoperative ED (P = 0.33). Neither peak systolic, end diastolic, nor resistive index were significant predictors of ED (P = 0.28, 0.28, and 0.25, respectively). This long-term follow-up of a large published series suggests that neither

    Erectile dysfunction (ED) is associated with cardiovascular disease (CVD); however, the association between change in ED status over time and future underlying CVD risk is unclear. The aim of this study was to investigate the association between change in ED status and Framingham CVD risk, as well change in Framingham risk. We studied 965 men free of CVD in the Boston Area Community Health (BACH) Survey, a longitudinal cohort study with three assessments. ED was assessed with the five-item International Index of Erectile Function at BACH I (2002-2005) and BACH II (2007-2010) and classified as no ED/transient ED/persistent ED. CVD risk was assessed with 10-year Framingham CVD risk algorithm at BACH I and BACH III (2010-2012). Linear regression models controlled for baseline age, socio-demographic and lifestyle factors, as well as baseline Framingham risk. Models were also stratified by age (≥/< 50 years). Framingham CVD risk and change in Framingham CVD risk were the main outcome measures. Transient and persistent ED was significantly associated with increased Framingham risk and change in risk over time in univariate and age-adjusted models. In younger men, persistent ED was associated with a Framingham risk that was 1.58 percentage points higher (95% confidence interval [CI]: 0.11, 3.06) and in older men, a Framingham risk that was 2.54 percentage points higher (95% CI: -1.5, 6.59), compared with those without ED. Change in Framingham risk over time was also associated with transient and persistent ED in men <50 years, but not in older men. Data suggest that even after taking into account other CVD risk factors, transient and persistent ED is associated with Framingham CVD risk and a greater increase in Framingham risk over time, particularly in younger men. Findings further support clinical assessment of CVD risk in men presenting with ED, especially those under 50 years. © 2014 International Society for Sexual Medicine.

    Several studies have indicated that erectile dysfunction (ED) patients also suffer from lower urinary tract symptoms (LUTS). We investigated a group of men with LUTS and assessed their sexual function with the aim of being able to predict ED risk factors and introduce ED treatments earlier for this patient group. International Prostate Symptom Score (IPSS), Overactive Bladder Symptoms Score (OABSS) and Sexual Health Inventory for Men (SHIM) score were obtained from 236 men with LUTS at their first out-patients visit. Clinical parameters such as body mass index, prostate volume, residual urine volume and prostate specific antigen were also evaluated. The relationship between the SHIM score and other clinical data was analyzed. According to the SHIM score, ED in men with LUTS was severe 15%, moderate 19%, moderate to mild 28%, mild 17%, normal 7% and data was incomplete in 14%. Based on the results of a multivariate analysis, aging (p urinary incontinence was a risk factor for severe and moderate ED (p = 0.005). Aging and OAB (notably urinary urge incontinence) are risk factors for severe and moderate ED in men with LUTS.

  16. Penile venous surgery for treating erectile dysfunction: Past, present, and future perspectives with regard to new insights in venous anatomy

    2016-06-01

    Full Text Available In the physiologic model of normal erectile function, a healthy veno-occlusive mechanism is essential to initiate and maintain a rigid erection. The surgical treatment of patients with venous leakage, which is synonymous with corporoveno-occlusive dysfunction (CVOD, was based on the decreased venous outflow during the erection process. The initial reports of short-term results were promising, but the long-term benefits of penile venous ligation surgery were limited. Most clinical guideline panels concluded that surgeries performed in an attempt to limit the venous outflow of the penis were not recommended. Consequently, this surgery was nearly abandoned in most medical societies worldwide. These unfavorable postoperative outcomes seemed attributable to the indispensable usage of electrocautery and insufficient venous management, based on conventional penile venous anatomy. Advances in better understanding of human penile venous anatomy has enabled the development of refined penile venous stripping surgery. The thorough stripping surgery is an even more radical procedure, which is an even more radical procedure, and seems to be a viable option for the treatment of CVOD, however, there is still a need for further study with well-defined diagnostic criteria, and standardized patient and partner outcome assessment.

    Full Text Available Objectives: To evaluate the improvement of Lower Urinary Tract Symptoms (LUTS and Erectile Function (EF evaluated before and after Open Simple Prostatectomy, focusing on which patients this procedure allows better outcomes in term of sexual activity. Material and methods: 50 men with large size benign prostatic hyperplasia (BHP greater than 80 gr were prospectively evaluated before and 6 months after Open Simple Prostatectomy (Freyer procedure between October 2012 to September 2013. Patients had a pre-operative transrectal ultrasound (TRUS for volume evaluation and filled pre and post operative questionnaires for International Prostate Symptom Score (IPSS and International Index of Erectile Function (IIEF-5 score. Results: Mean patients age was 71 years (D.S. 3,5, mean prostate volume results 103 ml (D.S. 23,7; regarding LUTS and EF, mean improvement of IPSS score was 15,3 (D.S. 4 and mean increase of IIEF-5 score was 3,4 (D.S.3. This study highlights a correlation between patients’ age and increase of IIEF-5 score; no correlation with prostate size was found. Conclusion: According to the EAU Guidelines 2014, large size BPH (over 80-100 mL with LUTS refractory to medical management continue to have open prostatectomy as the treatment of choice. In our experience we found not only an reduction of LUTS after the procedure but also an improvement of erectile function; this improvement was related with patient’s age.

    Sex is an important part of life for many people, therefore dealing with erectile problems, living with the effects of physical injury, changes in your appearance or side-effects of treatment can have an enormous impact on your sex life and relationships. Normal sexual behaviour and erectile function depends on a complex interaction between various body-systems, including the brain, nerves, blood-supply and hormones. All of these systems (alone or in combination) may be affected following mul...

    Purpose/objective: In this study, we evaluated in a serial manner whether radiation dose to the bulb of the penis is predictive of erectile dysfunction, ejaculatory difficulty (EJ), and overall satisfaction with sex life (quality of life) by using serial validated self-administered questionnaires. Methods and materials: Twenty-nine potent men with AJCC Stage II prostate cancer treated with three-dimensional conformal radiation therapy alone to a median dose 72.0 Gy (range: 66.6-79.2 Gy) were evaluated by determining the doses received by the penile bulb. The penile bulb was delineated volumetrically, and the dose-volume histogram was obtained on each patient. Results: The median follow-up time was 35 months (range, 16-43 months). We found that for D 30 , D 45 , D 60 , and D 75 (doses to a percent volume of PB: 30%, 45%, 60%, and 75%), higher than the corresponding median dose (defined as high-dose group) correlated with an increased risk of impotence (erectile dysfunction firmness score = 0) (odds ratio [OR] = 7.5, p = 0.02; OR = 7.5, p = 0.02; OR = 8.6, p = 0.008; and OR = 6.9, p = 0.015, respectively). Similarly, for EJD D 30 , D 45 , D 60 , and D 75 , doses higher than the corresponding median ones correlated with worsening ejaculatory function score (EJ = 0 or 1) (OR = 8, p = 0.013; OR = 8, p 0.013; OR = 9.2, p = 0.015; and OR = 8, p = 0.026, respectively). For quality of life, low (≤median dose) dose groups of patients improve over time, whereas high-dose groups of patients worsen. Conclusions: This study supports the existence of a penile bulb dose-volume relationship underlying the development of radiation-induced erectile dysfunction. Our data may guide the use of inverse treatment planning to maximize the probability of maintaining sexual potency after radiation therapy

Erectile dysfunction (ED is a possible invalidating symptom of PD. The aim of this study was to evaluate the prevalence, psychological impact, and risk factors of ED in patients with PD. The study was conducted by carrying out a retrospective analysis of the clinical records of 309 patients with PD who visited our andrology clinic. All patients underwent the following tests: body mass index, common blood tests and hormone assays, questionnaire for erectile function assessment, dynamic penile color Doppler ultrasonography, imaging of the penis at maximum erection with photographic poses according to Kelâmi, psychosexual impact evaluation with PD Questionnaire (symptom bother score, evaluation of depression symptoms with the Patient Health Questionnaire-9, and evaluation of the intensity of penile pain with the pain intensity numeric rating scale. ED was observed in 37.5% of the cases. We divided the cases into two groups: group A (PD + ED, 116 cases, and group B (PD without ED, 193 cases. After multivariate analysis, we concluded that the following comorbidities are independent risk factors for ED: dyslipidemia, obesity, chronic prostatitis, benign prostatic hyperplasia, and autoimmune diseases. A depressive disorder was observed in 62.4%, and it was more frequent in patients with PD + ED (91.37% versus 45.07% group B. Sexual bother was greater in group A compared with group B (9.7 versus 7.6. Intensities of depressive symptoms and

    Full Text Available Bariatric surgery is an effective treatment option for both obesity and obesity-related type 2 diabetes mellitus (T2DM. However, little is known regarding the effects of bariatric surgery on erectile dysfunction among patients with T2DM. Therefore, we investigated whether bariatric surgery would lead to structural and biochemical changes in the corpus cavernosum.Twenty-five male Otsuka Long-Evans Tokushima Fatty rats were assigned to either a control group (sham operation, n = 10 or a bariatric surgery group (gastric bypass surgery, n = 15. Four weeks after the operation, each group of rats was evaluated with an oral glucose tolerance test (OGTT. The penile intracavernous pressure was measured for erectile functional analysis. Histologic evaluation of the tissue was performed with Masson's trichrome staining. Endothelial nitric oxide synthase (eNOS, neuronal nitric oxide synthase (nNOS, Rho kinase, and 8-hydroxy-2-deoxyguanosine (8-OHdG levels in the corpus cavernosum were assayed by using western blot and ELISA.The mean body weight of the bariatric surgery group was lower than the control group (p = 0.002. The postoperative OGTT result was lower in the bariatric surgery group than in the control group (p = 0.014, and this was lower than the preoperative value (p = 0.037. The intracavernous pressure/mean arterial pressure ratio was higher in the bariatric surgery group compared to the control group (p = 0.021, and a higher cavernosum smooth muscle/collagen ratio was observed in the bariatric surgery group compared to the control group (p = 0.025.

    Few population-based studies in erectile dysfunction (ED) included subjects less than 40 years old and analyzed the several factors and consequences potentially associated with this condition. Evaluation of the prevalence of erectile dysfunction (ED) and associated factors in a sample of Brazilian men aged 18 to 40 years old. Cross-sectional study in which subjects were contacted in public places of 18 major Brazilian cities and interviewed using an anonymous questionnaire. Survey data were submitted to chi-squared, student's t-test and logistic regression analyses. The data were collected by means of a self-administered questionnaire with 87 questions about sociodemographic variables, general health, habits and lifestyle-related factors, sexual behavior and sexual difficulties, including ED which was assessed by a single question. Prevalence of ED in 1,947 men was 35.0% (73.7% mild, 26.3% moderate/complete). Greater frequency of ED was seen in subjects that never had information about sex, experienced difficulties in the beginning of sexual life and have never masturbated. ED was associated to lower level of education, but not to race, sexual orientation, employment or marital status. Also, no association was found between ED and smoking, alcoholism, obesity, sedentary life, diabetes, hypertension, cardiovascular disease, hyperlipidemia, depression or anxiety. ED caused negative impact in men's self-esteem, interpersonal relationships, work and leisure activities, and in sexual life satisfaction. Less than 10% of men with ED had received medical treatment for this problem. Prevalence of ED in this young population was high, mostly of mild severity. Low education and psychosocial problems were associated to ED and, due probably to the sample subjects' young age, no association was found with organic problems. Measures in the fields of education and psychosocial difficulties prevention would have a positive impact in the control of erectile dysfunction in the young

    Full Text Available Erectile dysfunction (ED affected the lives of more than 300 million men worldwide. Erectile dysfunction drugs (EDD, known as phosphodiesterase inhibitors (PDEIs, have been used for treatment of ED. It has been shown that oxidative stress plays an important role in the progression of erectile dysfunction. Oxidative stress can be alleviated or decreased by antioxidant enzymes. Therefore, the present study aims at investigating the changes in the activity of antioxidant enzymes such as superoxide dismutase, catalase, and glutathione reductase as well as protein expression of glutathione peroxidase and glutathione S-transferase after treatment of male rats with a daily dose of sildenafil (1.48 mg/kg, tadalafil (0.285 mg/kg and vardenafil (0.285 mg/kg for three weeks. In addition, levels of reduced glutathione and malondialdyhyde (MDA were assayed. The present study showed that sildenafil, vardenafil, and tadalafil treatments significantly decreased the levels of glutathione, MDA and the activity of glutathione reductase. In addition, vardenafil and sildenafil increased the activity of superoxide dismutase and catalase. Interestingly, western immunoblotting data showed that vardenafil induced the activity of glutathione peroxidase (GPX and its protein expression, whereas tadalafil and sildenafil inhibited such enzyme activity and its protein expression. In addition, the protein expression of GST π isozyme was markedly reduced after treatment of rats with sildenafil. It is concluded that ED drugs induced the activities of both SOD and catalase which consequently decreased MDA level. Therefore, decrement in MDA levels could increase nitric oxide–cGMP level which in turn promotes the erection mechanism.

    Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction. This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.

    Full Text Available Paragangliomas of the cauda equina are rare neuroepithelial tumors, usually manifesting clinically as sciatica. Here, we report a case of cauda equina paraganglioma with an unusual course in a 43-year-old man. His main complaints were erectile and sphincter dysfunction. The low back pain was initially ascribed to accidental injury. Magnetic resonance imaging revealed intradural tumor at the L2/L3 level. The patient underwent gross tumor resection, and the diagnosis of paraganglioma was based on neuropathologic examination. The symptoms completely resolved after tumor resection.

    Erectile dysfunction very frequently can be traced back to the real cause by means of angiography. Selective angiography is the method of choice in cases where other causes of circulatory disturbance have already been excluded, and non-invasive tests are expected to yield information of relevance to therapy. The qualitatively best angiographic results are obtained by examination under peridural anesthesia and by intracavitary injection of vaso-active substances. Selective arteriography is indicated in cases of primary or post-traumatic erectile dysfunction. It is a prerequisite of surgery for revascularisation of the pudendal-penile vascular bed.
