    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.

    The inability to achieve an erection of the penis sufficient for sexual activity is called erectile dysfunction (ED). In most cases, the diagnosis can be made by medical history. The prevalence of ED in men at the age of 65 has been reported to be up to 50%. Premature ejaculation has a prevalence, up to 20% and is the most frequent ejaculatory dysfunction. The etiology of ED can involve psychological, vascular, neurogenic, hormonal or urogenital pathologies. The main pathophysiological mechanisms of ED are vascular disorders such as diabetes mellitus and atherosclerosis. Because of the common pathophysiology, patients diagnosed with ED should have a diagnostic work-up for systemic vascular pathologies to prevent concomitant cardiac events. Treatment options include invasive and non-invasive procedures. PMID:26602851

  5. Imaging for evaluation of erectile dysfunction

    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.

    Full Text Available Abstract Background Men with erectile dysfunction often have concurrent medical conditions. Conversely, men with these conditions may also have underlying erectile dysfunction. The prevalence of unrecognized erectile dysfunction in men with comorbidities commonly associated with erectile dysfunction was determined in men invited to participate in a double-blind, randomized, placebo-controlled trial of sildenafil citrate. Methods Men ≥30 years old presenting with ≥1 erectile dysfunction risk factor (controlled hypertension, hypercholesterolemia, smoking, metabolic syndrome, stable coronary artery disease, diabetes, depression, lower urinary tract symptoms, obesity [body mass index ≥30 kg/m2] or waist circumference ≥40 inches, and not previously diagnosed with erectile dysfunction were evaluated. The screening question, "Do you have erectile dysfunction?," with responses of "no," "yes," and "unsure," and the Erectile Function domain of the International Index of Erectile Function (IIEF-EF were administered. Results Of 1084 men screened, 1053 answered the screening question and also had IIEF-EF scores. IIEF-EF scores indicating erectile dysfunction occurred in 71% (744/1053, of whom 54% (399/744 had moderate or severe erectile dysfunction. Of 139 answering "yes," 526 answering "unsure," and 388 answering "no," 96%, 90%, and 36%, respectively, had some degree of erectile dysfunction. The mean±SD (range number of risk factors was 2.9 ± 1.7 (3-8 in the "yes" group, 3.2 ± 1.7 (3-9 in the "unsure" group, and 2.6 ± 1.5 (2-8 in the "no" group. Conclusion Although awareness of having erectile dysfunction was low, most men with risk factors had IIEF-EF scores indicating erectile dysfunction. Erectile dysfunction should be suspected and assessed in men with risk factors, regardless of their apparent level of awareness of erectile dysfunction.

    Lalong-Muh, Julienne; Colm, Treacy; Steggall, Martin

    Prostate cancer is the most common cancer to affect men in the UK. Treatment options depend on the grade of tumour, the patient's co-existing diseases and choice of treatment. One potentially curative option is surgery, specifically a radical retropubic prostatectomy or variation thereof. As a consequence of the surgery, men commonly experience two side-effects: urinary incontinence and erectile dysfunction (ED). This paper outlines the clinical management of ED following surgery and aims to provide an overview of how to assess a man who has developed ED and discuss the various treatment options available, along with the efficacy in terms of recovery of erections. PMID:23448953

    2016-08-01

    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 PDE5is, proper

    Psychogenic factors are involved alone or in combination with organic causes in a substantial number of cases of erectile dysfunction. Epidemiologic studies have implicated the role of depressed mood, loss of self-esteem, and other psychosocial stresses in the cause of erectile dysfunction. A new definition and classification of psychogenic erectile dysfunction has been proposed based on recent clinical and research findings. According to this new classification, psychogenic erectile dysfunction is categorized as generalized or situational type, with subcategories of each type proposed. Traditional treatment approaches for psychogenic erectile dysfunction have included anxiety reduction and desensitization procedures, cognitive-behavioral interventions, guided sexual stimulation techniques, and couples' or relationship counseling. Recently, these approaches increasingly have been combined with pharmacologic therapy such as sildenafil. Special situations have been identified in which combining psychosocial interventions with medical therapy is recommended. These situations include problems of sexual initiation, low sexual desire, other sexual dysfunctions, and significant couples' or relationship problems. More research is needed on the role of psychosocial interventions in the treatment of erectile dysfunction.

    Full Text Available Erectile dysfunction (ED is a common problem seen among patients on hemodialysis (HD, but it is still a taboo subject in our country. The attention given to this sexual problem remained low, and the prevalence of ED among these patients has not been well characterized. We carried out this study in order to determine the prevalence and severity of ED in HD patients. We conducted a descriptive cross-sectional study in our HD unit in March 2013. ED was evaluated using the International Index Erection Function. Thirty patients with a mean age of 49.1 years were eligible for this study. The main causes of chronic kidney disease were hypertension (62.5% and diabetes (41.6%. The prevalence of ED was 80%, including 33.3% severe ED. Plasma levels of gonadotropins: luteinizing hormone (LH, follicule-stimulating hormone were in the standards except for one patient who had an elevated level of LH. Prolactin was elevated in four cases. ED was present in 8.4% of patients before the discovery of renal failure and in 91.6% of patients at the beginning of dialysis. For 19 patients (79.1%, the ED had increased during the dialysis sessions. A significant number of our HD patients presented with ED of varying degrees. Nephrologists should pay attention to the problem of ED in order to improve the quality of their life.

    Cigarette smoking is a leading cause of preventable morbidity and mortality in the United States. Although public policies have resulted in a decreased number of new smokers, smoking rates remain stubbornly high in certain demographics with 20% of all American middle-aged men smoking. In addition to the well-established harmful effects of smoking (i.e. coronary artery disease and lung cancer), the past three decades have led to a compendium of evidence being compiled into the development of a relationship between cigarette smoking and erectile dysfunction. The main physiologic mechanism that appears to be affected includes the nitric oxide signal transduction pathway. This review details the recent literature linking cigarette smoking to erectile dysfunction, epidemiological associations, dose dependency and the effects of smoking cessation on improving erectile quality.

    Arterial hypertension is a major risk factor for cardiovascular disease and affects approximately one third of the adult population worldwide. The vascular origin of erectile dysfunction is now widely accepted in the vast majority of cases. Erectile dysfunction is frequently encountered in patients with arterial hypertension and greatly affects their quality of life of hypertensive patients and their sexual partners. Therefore, the management of erectile dysfunction in hypertensive patients is of paramount importance. Unfortunately, erectile dysfunction remains under-reported, under-recognized, and under-treated in hypertensive patients, mainly due to the lack of familiarity with this clinical entity by treating physicians. This review aims to discuss the more frequent problems in the management of hypertensive patients with erectile dysfunction and propose ways to overcome these problems in everyday clinical practice.

    Full Text Available Objective: The aim of this study is to investigate the existence of erectile dysfunction in patients with obstructive sleep apnea syndrome (OSAS in which the other possible causes of erectile dysfunction were eliminated.Material and Methods: The study group consisted of 24 patients diagnosed as OSAS with polysomnographic evaluation, and 15 non-apneic controls (mean age; 41.0±8.8 and 42.3±7.9 year respectively whose comorbidities which might be associated with erectile dysfunction were excluded. Daytime sleepiness was evaluated by Epworth Sleepiness Scale (ESS and measurement of erectile function was performed by International Index of Erectile Function.Results: The rate of erectile dysfunction in OSAS and control groups were 54.2% and 33.3% respectively (p=0.204. The difference between mean erectile function scores of patient and control groups was non-significant (26.1±4.5 and 26.3±4.3 respectively, p=0.900. There was no correlation between erectile function scores and apnea hypnoea index (r=-0.140; p=0.395.Conclusion: Findings obtained from this study suggest that the high incidence of erectile dysfunction reported in OSAS patients seems to be related with concomitant comorbidities such as diabetes, atherosclerosis and neuroendocrine disorders rather than sleep apnea.

    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.

    Objective Diabetic erectile dysfunction is an intractable disease which results from both vascular and nervous dysfunction in penis. Calpain mediates the vascular dysfunction during hyperglycemia and is involved in some neurodegenerative diseases. This study was designed to investigate the role of calpain inhibition in improving diabetic erectile dysfunction in rats. Methods Type 1 diabetes was induced by intraperitoneal injection of streptozotocin at the dose of 60 mg/kg in rats. After 2 months, diabetic erectile dysfunction was confirmed by apomorphine test. Then the animals were divided into three groups: (I) nondiabetic control groups, (II) diabetic rats + vehicle and (III) diabetic rats + MDL28170. Two weeks later the erectile function was measured by electrical stimulation of the cavernous nerve and the ratio between intracavernosal pressure (ICP) and mean systemic arterial blood pressure (MAP) at the peak of erectile response was calculated. After that penis tissue was harvested. Calpain activity in corpus cavernosum was measured by western blot. Neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS) were observed by immunohistochemistry and western blot. The endothelial content in the cavernosum was measured by immunohistochemistry. Results The calpain activity was increased in diabetic rats and inhibited by MDL28170. The erectile function was improved by MDL28170 treatment. The expression of nNOS and eNOS, as well as the content of endothelium in corpus cavernosum were also increased by inhibition of calpain. Conclusions Calpain activation may play a role in the erectile dysfunction of diabetic rats. Inhibition of calpain could improve diabetic erectile dysfunction by increasing expression of nNOS and eNOS in the corpus cavernosum. This could be a novel therapeutic target to protect the erectile function in diabetic patient.

    Aim: To determine the relationship between metabolic syndrome (MS) and erectile dysfunction (ED) and to see which risk factors correlated the best with ED. Methods: Seventy-nine cardiology clinic outpatients with coronary artery disease (CAD) and lipid metabolism disorder were recruited. They were categorized as having MS,hypertension (blood pressure greater than 130/85 mmHg) and dyslipidemia. ED was classified based on International Index of Erectile Function scores. Patients were grouped into quartiles based on body mass index (BMI). Chi-square,Pearson's correlation and regression tests were used for statistical analysis. Results: The mean age of the patients was 56.6 years. ED was diagnosed in 59 (74.7 %) of the 79 patients. In the 38 patients with MS, all had ED. ED was not significantly correlated with cholesterol levels (P>0.05), but was found often in patients who had both hypercholesterolemia and HT (P<0.01). Nineteen(76 %) of the 25 patients who had dyslipidemia had ED. However, ED wasnot significantly correlated with dyslipidemia (P>0.05). Tweenty-two of the 23 patients who had BMI greater than30 had ED, which was significantly more prevalent than that in those who had normal BMI (P<0.01). ED was seen in 38 of 53 smoker patients. Although ED was more prevalent in cigarette smokers, it was not significantly different from non-smokers (P>0.5). Conclusion: ED is present in a high percentage of patients with MS. Among multiple risk factors for ED, MS correlates the most highly. The next most important risk group is the patients with hypertension +hypercholestrolemia and obesity (BMI>30).

    The treatment of erectile dysfunction (ED) has been a fascination involving multiple medical specialities over the past century with urologic, cardiac and surgical experts all contributing knowledge toward this multifactorial disease. With the well‑described association between ED and cardiovascular disease, angiography has been utilized to identify vasculogenic impotence. Given the success of endovascular drug‑eluting stent (DES) placement for the treatment of coronary artery disease, there has been interest in using this same technology for the treatment of vasculogenic ED. For men with inflow stenosis, DES placement to bypass arterial lesions has recently been reported with a high technical success rate. Comparatively, endovascular embolization as an approach to correct veno‑occlusive dysfunction has produced astonishing procedural success rates as well. However, after a thorough literature review, arterial intervention is only recommended for younger patients with isolated vascular injuries, typically from previous traumatic experiences. Short‑term functional outcomes are less than optimal with long‑term results yet to be determined. In conclusion, the hope for a minimally invasive approach to ED persists but additional investigation is required prior to universal endorsement.

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

    Directory of Open Access Journals (Sweden)

    García-Perdomo, Herney Andrés

    2015-07-01

    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.

    AIM: Erectile dysfunction is a common problem among patients with cardiovascular diseases and the influence of cardiovascular drugs is much debated. The aim of this study was to evaluate the short term potential for different cardiovascular drugs to affect the risk of being prescribed a drug...... against erectile dysfunction. METHODS: We employed a symmetry analysis design and included all Danish male individuals born before 1950 who filled their first ever prescription for a cardiovascular drug and a 5-phosphodiesterase inhibitor within a 6 month interval during 2002-2012. If the cardiovascular...... drug induces erectile dysfunction, this would manifest as a non-symmetrical distribution of subjects being prescribed the cardiovascular drug first vs. persons following the opposite pattern. Furthermore, we calculated the number of patients needed to treat for one additional patient to be treated...

    In humans androgen decline is presented as a clinical picture which includes decreased sexual interest, diminished erectile capasity, delayed or absent orgasms and reduced sexual pleasure. Additionally, changes in mood, diminished well being, fatigue, depression and irritability are also associated with androgen insufficiency. The critical role of androgens on the development, growth, and maintanence of the penis has been widely accepted. Although, the exact effect of androgens on erectile physiology still remains undetermined, recent experimental studies have broaden our understanding about the relationship between androgens and erectile function. Preclinical studies showed that androgen deprivation leads to penile tissue atrophy and alterations in the nerve structures of the penis. Furthermore,androgen deprivation caused to accumulation of fat containing cells and decreased protein expression of endothelial and neuronal nitric oxide synthases (eNOS and nNOS), and phosphodiesterase type-5 (PDE-5), which play crucial role in normal erectile physiology. On the light of the recent literature, we aimed to present the direct effect of androgens on the structures, development and maintanence of penile tissue and erectile physiology as well. Furhermore,according to the clinical studies we conclude the aetiology, pathophysiology, prevalance, diagnosis and treatment options of hypogonadism in aging men.

    Full Text Available Psychogenic erectile dysfunction (ED has been defined as the persistent inability to attain and maintain an erection sufficient to permit sexual performance. It shows a high incidence and prevalence among men, with a significant impact on the quality of life. Few neuroimaging studies have investigated the cerebral basis of erectile dysfunctions observing the role played by prefrontal, cingulate, and parietal cortices during erotic stimulation. In spite of the well-known involvement of subcortical regions such as hypothalamus and caudate nucleus in male sexual response, and the key role of nucleus accumbens in pleasure and reward, poor attention was paid to their role in male sexual dysfunction. In this study, we determined the presence of grey matter (GM atrophy patterns in subcortical structures such as amygdala, hippocampus, nucleus accumbens, caudate nucleus, putamen, pallidum, thalamus, and hypothalamus in patients with psychogenic ED and healthy men. After Rigiscan evaluation, urological, general medical, metabolic and hormonal, psychological and psychiatric assessment, 17 outpatients with psychogenic ED and 25 healthy controls were recruited for structural MRI session. Significant GM atrophy of nucleus accumbens was observed bilaterally in patients with respect to controls. Shape analysis showed that this atrophy was located in the left medial-anterior and posterior portion of accumbens. Left nucleus accumbens volumes in patients correlated with low erectile functioning as measured by IIEF-5 (International Index of Erectile Function. In addition, a GM atrophy of left hypothalamus was also observed. Our results suggest that atrophy of nucleus accumbens plays an important role in psychogenic erectile dysfunction. We believe that this change can influence the motivation-related component of sexual behavior. Our findings help to elucidate a neural basis of psychogenic erectile dysfunction.

    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.

    Herbal medicine long has been used in the management of sexual dysfunction, including erectile dysfunction. Many patients have attested to the efficacy of this treatment. However, is it evidence-based medicine? Studies have been done on animal models, mainly in the laboratory. However, randomized controlled trials on humans are scarce. The only herbal medications that have been studied for erectile dysfunction are Panax ginseng, Butea superba, Epimedium herbs (icariin), Tribulus terrestris, Securidaca longipedunculata, Piper guineense, and yohimbine. Of these, only Panax ginseng, B. superb, and yohimbine have published studies done on humans. Unfortunately, these published trials on humans were not robust. Many herbal therapies appear to have potential benefits, and similarly, the health risks of various phytotherapeutic compounds need to be elucidated. Properly designed human trials should be worked out and encouraged to determine the efficacy and safety of potential phytotherapies. PMID:21948222

    Aging is associated with ED. Although age-related ED is attributed largely to increased oxidative stress and endothelial dysfunction in the penis, the molecular mechanisms underlying this effect are not fully defined. We evaluated whether endothelial nitric oxide synthase (eNOS) uncoupling in the aged rat penis is a contributing mechanism. Correlatively, we evaluated the effect of replacement with eNOS cofactor tetrahydrobiopterin (BH(4)) on erectile function in the aged rats. Male Fischer 344 'young' (4-month-old) and 'aged' (19-month-old) rats were treated with a BH(4) precursor sepiapterin (10 mg/kg intraperitoneally) or vehicle for 4 days. After 1-day washout, erectile function was assessed in response to electrical stimulation of the cavernous nerve. Endothelial dysfunction (eNOS uncoupling) and oxidative stress (thiobarbituric acid reactive substances, TBARS) were measured by conducting western blot in penes samples. Erectile response was significantly reduced in aged rats, whereas eNOS uncoupling and TBARS production were significantly increased in the aged rat penis compared with young rats. Sepiapterin significantly improved erectile response in aged rats and prevented increase in TBARS production, but did not affect eNOS uncoupling in the penis of aged rats. These findings suggest that aging induces eNOS uncoupling in the penis, resulting in increased oxidative stress and ED. PMID:21289638

    The classical etiology of erectile dysfunction (ED) comprises aging and vascular, neurogenic, psychological and hormonal components. Recent studies have shown that ED can be the forerunner of serious cardiovascular disturbances. It has also been reported that peripheral neuropathy and microvascular injuries caused by pathophysiological changes in patients with diabetes and obesity lead to ED in a significant number of such cases. These patients develop clinically significant ED and comprise a significant portion of the patient group which do not respond to PDE-5 inhibitors. Testosterone has been shown to increase the expression of PDE-5. This function of testosterone supports its effect on the regulation of erection and increasing the sexual libido. In view of the complexity of ED, as well as the effect of testosterone on erection, it is concluded that PDE-5 inhibitors in combination with testosterone replacement would be a better therapy alternative in the management of erectile dysfunction in hypogonadal patients.

    Erectile dysfunction (ED) is a common medical disorder whose prevalence is increasing worldwide. Modifiable risk factors for ED include smoking, lack of physical activity, wrong diets, overweight or obesity, metabolic syndrome, and excessive alcohol consumption. Quite interestingly, all these metabolic conditions are strongly associated with a pro‑inflammatory state that results in endothelial dysfunction by decreasing the availability of nitric oxide (NO), which is the driving force of the blood genital flow. Lifestyle and nutrition have been recognized as central factors influencing both vascular NO production, testosterone levels, and erectile function. Moreover, it has also been suggested that lifestyle habits that decrease low‑grade clinical inflammation may have a role in the improvement of erectile function. In clinical trials, lifestyle modifications were effective in ameliorating ED or restoring absent ED in people with obesity or metabolic syndrome. Therefore, promotion of healthful lifestyles would yield great benefits in reducing the burden of sexual dysfunction. Efforts, in order to implement educative strategies for healthy lifestyle, should be addressed.

    In 30 to 50% erectile dysfunctions are due to vascular disorders. Roughly a third of these vasculogenic disturbances is based on venous disorders. These venous-induced erectile failures may be objectivated and radiologically located via dynamic cavernosography, combined with a simultaneous recording of a cavernous pressure profile. Based on over 130 examinations it was possible to provide both an exact description of the normal venous drainage in normal potent men and to give a good idea of the different venous leakages in patients complaining of erectile dysfunctions. Congenital and acquired penile deviations along with Peyronie's disease may also be appropriate for dynamic cavernosography.

    Cancer can cause sexual adverse effects by direct and indirect pathways. It can involve sexual organs, indirectly affect body image, or cause fatigue or depression with subsequent effects on libido. Erectile dysfunction (ED), the inability to obtain or maintain an erection firm enough for sexual intercourse, can also result from adverse effects of cancer treatment, such as fatigue, pain, or anxiety about therapy. In addition, depressed feelings about having cancer can affect sexuality, causing a range of signs and symptoms that can lead to ED. Chemotherapy, hormone therapy, surgery, and radiation can all cause sexual adverse effects. Additional factors that play a role include patient age and degree of ED before starting cancer treatment. In this article, we discuss how chemotherapy, hormone therapy, surgery, and radiation affect erectile function as well as possible treatment options for ED. PMID:27072383

    Prescription sales of Testosterone and erectile aids such as phosphodiesterase-5 inhibitors are at an all-time high, underscoring the importance of hypogonadism (HG) and erectile dysfunction (ED) to men's health. The effect of these debilitating conditions has a major impact on the quality of men's lives. Some risk factors for HG or ED including aging, obesity, smoking, and a sedentary lifestyle. Notably, these are the same risk factors for several other medical co-morbidities that contribute to significant morbidity and mortality in men. HG and ED often co-exist with cardiovascular disease, diabetes, and osteoporosis. This review will explore these three co-morbidities that overlap with HG and ED, and will provide a review of their relationship with each other.

  18. Oestrogen-androgen crosstalk in the pathophysiology of erectile dysfunction

    2003-01-01

    Ageing in man is associated with a decline in testosterone following changes in the hypothalamo-pituitary-testicular axis. This may offset the physiologic equilibrium between oestrogen and androgen and at some point when the ratio of free testosterone to oestradiol reaches a critical level, the oestrogenic gonadotropin suppressive effect predominates with decreased release of FSH and LH. Adding to this endocrinal complexity is the continued peripheral conversion to oestradiol through aromatisation. Although the androgen deficiency is not the sole cause for impotence in the elderly, there is a gradual decrease in nocturnal penile tumescence (NPT) and spontaneous morning erections with ageing. Despite the age related increase in oestrogen levels, the information on the pathophysiological role of the "female hormone" in erectile dysfunction has been scanty. Together with our identification of oestrogen receptors within the penile cavernosum, we have delineated dysfunctional changes on male erection mediated by oestradiol.These findings parallel the recent concerns over environmental oestrogens on fertility declines in young men. Oestrogenic activity is also present in plants and thereby in human diet. These phytoestrogens are structurally and functionally similar to oestradiol and more potent than the environmental oestrogenic chemicals such as organochlorine and phenolic compounds. Thus in the light of growing concerns of possible compromising effects on sexuality by endogenous and environmental oestrogens, we are faced with the scientific need to delineate their role on the mechanism of male erectile pathway in health and disease for clinical correlates and prognostics.

  20. Erectile dysfunction and central obesity: an Italian perspective

    Directory of Open Access Journals (Sweden)

    Giovanni Corona

    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.

Over the last few decades, advances in our understanding of erectile physiology and improvements in diagnostic testing have restructured our understanding of ED and its etiologies. Although psychogenic ED is more prevalent in the younger population, at least 15%–20% of these men have an organic etiology. Organic ED has been shown to be a predictor of increased future morbidity and mortality. As such, a thorough work‑up should be employed for any man with complaints of sexual dysfunction. Oftentimes a treatment plan can be formulated after a focused history, physical exam and basic lab‑work are conducted. However, in certain complex cases, more testing can be employed. The major organic etiologies can be subdivided into vascular, neurologic, and endocrine. Specific testing should be directed by clinical clues noted during the preliminary evaluation. These tests vary in degree of invasiveness, precision, and at times may not affect treatment. Results should be integrated into the overall clinical picture to assist in diagnosis and help guide therapy.

    Erectile dysfunction (ED) is defined as the inability to attain or maintain an erection sufficient for satisfactory sexual performance. This cross-sectional study was conducted on patients on hemodialysis (HD) in Shiraz, Iran, using the International Index of Erectile Dysfunction questionnaire for determination of the frequency and severity of ED in these patients. We used the Chi-square, Mann-Whitney, Kruskal-Wallis and Pearson's correlation coefficient tests for statis-tical analysis. A total of 73 patients were enrolled into this study. The mean score of ED was 10.3 ± 6.3 (total score 25). The prevalence of ED of various degrees was 87.7%. There was a significant correlation between different degrees of ED and age (P = 0.002); it was significantly higher in patients older than 50 years (P = 0.005). Also, ED was more common in patients whose Kt/V was <1.2 (P = 0.04). Our study suggests that ED is a major health concern in patients on HD. Improvement of ED may improve their quality of life. Our results can give the basic data for future research in this field. PMID:21422619

    Acute ST elevation myocarclial infarction has high mortality and morbidity rates.The majority of patients with this condition face erectile dysfunction in addition to other health problems,In this study,we aimed to investigate the effects of two different reperfusion strategies,primary angioplasty and thrombolytic therapy,on the prevalence of erectile dysfunction after acute myocardial infarction.Of the 71 patients matching the selection criteria,45 were treated with primary coronary angioplasty with stenting,and 26 were treated with thrombolytic agents.Erectile function was evaluated using the International Index of Erectile Function in the hospital to characterize each patient's sexual function before the acute myocardial infarction and 6 months after the event.The time required to restore blood flow to the artery affected by the infarct was found to be associated with the occurrence of erectile dysfunction after acute myocardial infarction.The increase in the prevalence of erectile dysfunction after acute myocardial infarction was 44.4% in the angioplasty group and 76.9% in the thrombolytic therapy group (P=0.008).In conclusion,this study has shown that reducing the time of reperfusion decreases the erectile dysfunction prevalence,and primary angioplasty is superior to thrombolytic therapy for decreasing the prevalence of erectile dysfunction after acute myocardial infarction.

  4. Pathophysiology of Erectile Dysfunction - an Organisation/Activation Concept

    Full Text Available Erection supposes a process regulated by hormonal and neuro-vascular mechanisms on both cerebral and peripheral levels. The current understanding of erectile function and dysfunction (ED does not provide, however, a coherent model that accounts for the integration of sex hormones action and neuro-vascular mechanisms. Herein we suggest a model that involves organising and activating roles of sex steroids and neurovascular mechanisms in the regulation of erectile response. The organising role of hormones initiates during fetal life when androgens evoke both organogenesis of a penis and morphogenesis of a male type structure of sexually dimorphic brain regions (SDBR responsible for male sexual behavior. Due to androgen-stimulation, penile growth proceeds in early childhood, is accelerated at puberty and ceases thereafter despite high androgen levels. Similarly, masculinisation of SDBR may extend to the adulthood but these structures may not be susceptible to hormonal manipulations thereafter. The activating component of erection appears also on both cerebral and peripheral levels. Since puberty male type of androgen/estrogen balance may simultaneously activate cerebral sympathetic tone responsible for sexual drive (libido and parasympathetic tone responsible for erectile response on spinal cord level. On periphery the neuro-vascular activation of erection is present since fetal life and not dependent on libido. ED, the inability to achieve and maintain the erection to penetrate the vagina, may be of developmental origin as a primary failure or may derivate from organic or psychogenic diseases as secondary failure. As primary, ED may result from the lack or insufficient organising role of sex hormones on penile and behavioral levels, androgen-treatment will be necessary. In turn, secondary ED is more frequent, may result predominantly from the disturbances in the neuro-vascular erection activating mechanisms, and is less responsive to androgen-treatment.

    The introduction of oral phosphodiesterase-5 inhibitors (PDE5ls) in the late 1990s and early 2000s revolutionized the field of sexual medicine and PDE5ls are currently first-line monotherapy for erectile dysfunction (ED). However, a significant proportion of patients with complex ED will be therapeutic non-responders to PDE5I monotherapy. Combination therapy has recently been adopted for more refractory cases of ED, but a critical evaluation of current combination therapies is lacking. A thorough PubMed and Cochrane Library search was conducted focusing on the effectiveness of combination therapies for ED in therapeutic non-responders to PDE5I therapy. Journal articles spanning the time period between January 1990 and December 2010 were reviewed. Criteria included all pertinent review articles, randomized controlled trials, cohort studies and retrospective analyses. References from retrieved articles were also manually scanned for additional relevant publications. Published combination therapies include PDE5I plus vacuum erectile device (VED), intraurethral medication, intracavernosal injection (ICI), androgen supplement, a-blocker or miscellaneous combinations. Based on this review, some of these combination treatments appeared to be quite effective in preliminary testing. Caution must be advised, however, as the majority of combination therapy articles in the last decade have numerous limitations including study biases and small subject size. Regardless of limitations, present combination therapy research provides a solid foundation for future studies in complex ED management.

    The main cause of erectile dysfunction (ED) is organic in nature, with vascular etiologies being the most common risk factors. Although there have been sufficient data on the relationship between ED and several well-recognized risk factors, including aging, coronary artery disease, atherosclerosis, diabetes mellitus, dyslipidemia, high blood pressure,and pelvic surgeries, little attention has been paid by the urologists to the role of lifestyle factors in ED. However,accumulating data from basic science and clinical studies have determined a link between the occurrence of ED and a number of lifestyle factors, such as smoking, obesity, alcohol consumption, and lack of physical activity. The application of findings from animal and human studies to the clinical practice regarding the modification of lifestyle factors could help improving ED as well as reducing the risks of developing cardiovascular diseases. This communication addresses the impact of lifestyle factors on erectile function and the potential benefits of modifying these factors to improve ED in respect to the current evidence.

    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. PMID:26904415

    The prevalence of erectile dysfunction (ED) in 114 patients with prostate cancer treated with radical prostatectomy was examined to determine the efficacy of an ED care program in which nurse-provided education plays a fundamental role in the detection and follow-up of ED as well as in treatment compliance. The nursing program consists of four visits during which specific treatment-related information, education and support, active listening, and selection of the treatment best suited to each patient (in consultation with the healthcare team) are provided. One month following bladder catheter removal, 77 of the 114 patients (69%) in the study had ED, with a majority suffering from severe ED. A nursing care program could help minimize ED and enable patients to adapt to their new situation. PMID:23022944

    Full Text Available Erectile dysfunction (ED or male impotence is defined as the inability to have or sustain an erection long enough to have a meaningful sexual intercourse. ED tends to occur gradually until the night time or early morning erections cease altogether or are so flaccid that successful intercourse does not occur. Sexual health is an important determinant of quality of life. Today, millions of men, young and old, suffer from ED due to high levels of synthetic hormones (known as Xenoestrogens in our diet/environment; nutritionally imbalanced diet resulting from poor quality of produces; and extremely low levels of testosterone. To overcome the problem of sexual (or ED various natural aphrodisiac potentials are preferred. The present review discusses about aphrodisiac potential of plants, its biological source, common name, part used and references, which are helpful for researchers to develop new aphrodisiac formulations.

    The interest toward sex-related diseases keeps growing through the years. In this review, we focus our attention on erectile dysfunction (ED), a condition that caught much attention especially after the introduction on the market of phosphodiesterase 5 inhibitors such as the well-known sildenafil. Here, we briefly describe both the etiology of ED and the available treatments, examining then extensively some natural derivatives that, coming from traditional medicine, could represent promising starting points for the development of alternative remedies. In fact, herbal remedies from several parts of the world have been traditionally known for long, and were recently reconsidered and are now being studied to demonstrate their eventual potential in the treatment of ED. Among the various examples reported in the literature and reviewed here, plants and extracts containing polyphenols—especially a class of compounds called kraussianones—appear to be particularly effective and promising against ED.

    Sexual dysfunction is common in patients with prostate cancer (PC) following radical prostatectomy (RP). Review the available literature concerning prevention and management strategies for post-RP erectile function (EF) impairment in terms of preoperative patient characteristics, intra and postoperative factors that may influence EF recovery, and postoperative treatments for erectile dysfunction (ED). A literature search was performed using Google and PubMed database for English-language original and review articles, either published or e-published up to July 2013. The literature still demonstrates a great inconsistency in the definition of what is considered normal EF both before and after RP. Thus, using validated psychometric instruments with recognized cut-offs for normalcy and severity during the pre- and post-operative evaluation should be routinely considered. Therefore, a comprehensive discussion with the patient about the true prevalence of postoperative ED, the concept of spontaneous or pharmacologically-assisted erections, and the difference between "back to baseline" EF and "erections adequate enough to have successful intercourse" clearly emerge as key issues in the eventual understanding of post-RP ED prevention and promotion of satisfactory EF recovery. Patient factors (including age, baseline EF, comorbid conditions status), cancer selection (non- vs. uni- vs. bilateral nerve-sparing), type of surgery (i.e., intra vs. inter vs. extrafascial surgeries), surgical techniques (i.e., open, laparoscopic and robotically-assisted RP), and surgeon factors (i.e., surgical volume and surgical skill) represent the key significant contributors to EF recovery. A number of preclinical and clinical data show that rehabilitation and treatment in due time are undoubtedly better than leaving the erectile tissue to its unassisted postoperative fate. The role of postoperative ED treatment for those patients who received a non-nerve-sparing RP was also extensively

    International Nuclear Information System (INIS)

    Objective: To determine the prevalence of Erectile Dysfunction (ED) in hemodialysis patients (HD) and to study the associated changes in sex hormones in these patients. Methodology: This is a hospital based cross sectional study conducted at hemodialysis units of Shalamar and Mayo Hospitals, Lahore from January to March 2008. All male patients with ESRD on maintenance (HD), whose spouses were alive and able to perform intercourse, were included in the study. Patients with cognitive and communication deficits were excluded from study. International index of erectile function-5(IIEF-5), adopted in Urdu was used for determination of prevalence of ED. Demographic data was collected and sex hormones (total testosterone, Dihydroepiandrosteronediones (DHEA), Follicle Stimulating Hormone (FSH), Leutinizing Hormone (LH) and serum Prolactin) were measured. Results: A total number of fifty patients were included in the study. The major cause of ESRD was diabetes mellitus 28 (56%). The prevalence of ED was 86% with a mean IIEF-5 score 10.36 + 7.13. The majority of patients, 33 (66%), were suffering from a severe degree of ED. The total testosterone level was low in 30 (60%) patients and DHEA were low normal in most of patients, 46 (92%). Compared to patients with non-ED, those with ED had a significantly lower DHEA (1.93 +- 0.73 vs 0.81 +- 0.11, p value = 0.007). Total testosterone and DHEA had a negative correlation with age and diabetes mellitus. FSH showed a variable response in these patients, it was low ( 9.74 mIU/ ml) in eight patients. LH was low ( 7.8 mIU/ml) in fifteen patients. FSH and LH showed a positive correlation with duration of dialysis. Prolactin level was low in 21(42%) patients. Total testosterone, FSH, LH and Prolactin had no association with ED. Conclusion: The majority of the patients suffering from ESRD, on maintenance HD had ED. DHEA was significantly lower in patients with ED, compared to those with no-ED. Total testosterone and DHEA had an inverse

    We evaluated the impact of total prostate volume (TPV) on the international index of erectile function-5 (IIEF) and the premature ejaculation diagnostic tool (PEDT). A cross-sectional study was conducted that included 8336 men who had participated in a health examination. PEDT, IIEF and transrectal ultrasonography were used. A full metabolic work-up and serum testosterone level checks were also performed. The median age of participants was 51.0 years. In total, 40.1% had IIEF scores ≤16. Additionally, 24.7% were classified as demonstrating premature ejaculation (PE) (PEDT > 10). The severity of erectile dysfunction (ED) significantly increased with the TPV (p trend < 0.001). After adjusting for potential confounding factors, the odds ratio (OR) for IIEF scores ≤ 16 significantly increased in the group with TPVs of 30-39 cm(3) and the group with TPVs ≥ 40 cm(3) compared with the group with TPVs ≤ 19 cm(3) (TPV 30-39 cm(3), OR: 1.204, 95% confidence interval: 1.034-1.403; TPV ≥ 40 cm(3), OR: 1.326: 95% confidence interval: 1.051-1.733) and this relationship was maintained after adjusting for propensity score (TPV ≥ 30 cm(3), OR: 1.138: 95% confidence interval: 1.012-1.280). However, neither PEDT nor PE was correlated with TPV. In conclusion, TPV is significantly and independently correlated with IIEF but not with PEDT. Future investigations should explore the temporal relationship between TPV and ED. PMID:27145693

    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.

    Men with type 2 diabetes mellitus (T2DM) and erectile dysfunction (ED) have greater risk of cardiovascular events than T2DM men without ED, suggesting ED as a predictor of cardiovascular events in diabetic men. However, molecular mechanisms underlying endothelial dysfunction in the diabetic penis explaining these clinical observations are not known. We evaluated whether the temporal relationship between ED and endothelial dysfunction in the systemic vasculature in T2DM involves earlier redox imbalance and endothelial nitric oxidase synthase (eNOS) dysfunction in the penis than in the systemic vasculature, such as the carotid artery. Rats were rendered T2DM by high-fat diet for 2 weeks, followed by an injection with low-dose streptozotocin. After 3 weeks, erectile function (intracavernosal pressure) was measured and penes and carotid arteries were collected for molecular analyses of eNOS uncoupling, protein S-glutathionylation, oxidative stress (4-hydroxy-2-nonenal, 4-HNE), protein expression of NADPH oxidase subunit gp91(phox) , endothelium-dependent vasodilation in the carotid artery, and non-adrenergic, non-cholinergic (NANC)-mediated cavernosal relaxation. Erectile response to electrical stimulation of the cavernous nerve and NANC-mediated cavernosal relaxation was decreased (p < 0.05), while relaxation of the carotid artery to acetylcholine was not impaired in T2DM rats. eNOS monomerization, protein expressions of 4-HNE and gp91(phox) , and protein S-glutathionylation, were increased (p < 0.05) in the penis, but not in the carotid artery, of T2DM compared to non-diabetic rats. In conclusion, redox imbalance, increased oxidative stress by NADPH oxidase, and eNOS uncoupling, occur early in T2DM in the penis, but not in the carotid artery. These molecular changes contribute to T2DM ED, while vascular function in the systemic vasculature remains preserved. PMID:27153512

    Electrophysiological monitoring of the activity of the penile sympathetic skin responses (PSSR) in healthy men and patients with erectile dysfunction (ED). Methods: PSSR were recorded from the skin of penis with disk electrodes at the time of electric stimulation of left median nerves. Results: PSSR were recorded from all the healthy men and almost all the patients. In healthy men the latency of P0, the latency of N1, the duration of N1 and the amplitude of N1 were 1249 ± 111 ms, 2239 ± 286 ms, 1832 ± 505 ms and 470 μV (median), respectively. In ED patients the latency of P0, the latency of N1, the duration of N1 and the amplitude of N1 were 1467 ± 183 ms ( P < 0.01), 2561±453 ms (P <0.05), 2560±861 ms (P <0.01) and 91 μV (P <0.01), respectively. The normal latency of P0 was less than 1471 ms. The normal amplitude of N1 was more than 235 μV. According to this normal value, of 20 patients 11 showed longer latency of P0, and 14 showed lower amplitude of N1 as compared with those of normal subjects.Conclusion: PSSR can be used as an electrophysiological method in assisting the diagnosis of ED.

  4. Growth factors for therapeutic angiogenesis in hypercholesterolemic erectile dysfunction

    2008-01-01

    The past decade has seen an explosion of new information on the physiology of penile erection, and pathophysiology of erectile dysfunction (ED). Hypercholesterolemia is a chronic condition that can lead to degeneration in the vasculature bed and can result in ED if the penile vasculature is involved. Angiogenesis is the growth of new blood vessels from preexisting vasculature. Therapeutic angiogenesis seeks to harness the mechanisms of vascular growth to treat disorders of inadequate tissue perfusion, such as coronary artery disease and ED. There have been tremendous changes in the field of therapeutic angiogenesis over the past decade, and there is much promise for the future.Initial preclinical work with cytokine growth factor delivery resulted in a great deal of enthusiasm for the treatment of ischemic heart and/or peripheral vascular disease, though clinical studies have not achieved similar success. With an increased understanding of the complex mechanisms involved in angiogenesis, novel therapies which target multiple different angiogenic pathways are also being developed and tested. The penis is a convenient tissue target for gene therapy because of its external location and accessibility, the ubiquity of endothelial lined spaces, and low level of blood flow, especially in the flaccid state. Therapeutic angiogenesis is an exciting field that continues to evolve. This review will focus on the development of growth factors for hypercholesterolemic ED, the use of various growth factors for ED therapy, their routes of delivery, and the results in animal studies.

    To explore the efficacy of sildenafil on erectile dysfunction (ED) of newlyweds, the author studied 60 outpatients within a month of marriage, who suffered from sexual intercourse (SI) failure caused by ED and showed no improvement after receiving sex education and psychological consultation. The patients were given oral sildenafil, 100 mg for the first and second times, 50 mg for the third and fourth times, no more than once every day, with a 1- to 3-day break between every two times. Four times of sildenafil administration formed one course of treatment. Sildenafil was taken 1 h before SI and was aided with adequate sexual stimulation. The rates of successful SI due to improved erection during and after a course of sildenafil treatment were 93.3% (56/60) and 85% (51/60), both P > 0.05. In the groups with one and more than one SI failure the successful SI rates after a sildenafil treatment course were 93.1% (27/29) and 77.4% (24/31), both P > 0.05. Oral sildenafil with psychological therapy in the treatment of ED of newlyweds proves to be effective in restoring the patients' sexual function and relieving their mental pressure or stress.

    The advent of phosphodiesterase type 5 (PDE5) inhibition as oral therapy has significantly revolutionized both clinical and basic research in the area of erectile dysfunction (ED). Much of this progress is due to a better understanding in the last three decades of the various pathophysiological and cellular mechanisms contributing to ED. Apart from the three available PDE5 inhibitors viz., sildenafil, tadalafil and vardenafil globally at the turn of this century, four other PDE inhibitors have joined the armament in recent time; these include avanafil, lodenafil, mirodenafil and udenafil. All seven PDE inhibitors are effective therapies for the treatment of ED in men. There is no significant difference among them with respect to efficacy, safety profile and tolerability. As such, good safety profiles have widened the horizon in patient choice, selectivity and efficacy. With the ease of oral administration and better patient compliance, other measures of the past, including intracavernosal injections and non-pharmacological treatments have been relegated to second-line therapy for most patients with ED. But, PDE inhibitors as first-line oral therapies are effective in about 75% of male patients diagnosed with ED. Intracavernous injection (IC) therapy with PGE1 (alprostadil) for about 10% patient-usage in general is a well-known effective and well tolerated treatment for men with ED. It is also recommended as a second line therapy for ED along with urethral and topical PGE1. Transurethral PGE1 is less effective compared to IC PGE1. Also the transurethral dosage options are 125 to 1,000 µg, while the IC dosage options are 5 to 40 µg. The topical PGE1 (300 µg in 100 mg of the cream) is also less effective compared to IC PGE1. Topical cream is not approved in many countries as yet. Other existing vasoactive agents such as papaverine, and alpha adrenergic blockers and their combinations and the ever increasing number of other agents in the pipeline including nitric

    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.

    Full Text Available Abstract Introduction Hyperprolactinemia is an uncommon cause of erectile dysfunction in men. Paget's disease of the skull is a relatively common disease. This case proposes a rare example of a causative link between the two and how treatment of the Paget's disease with bisphosphonates helped the patient regain erectile function. Case presentation A 67-year-old man with Paget's disease of the skull presented with prostatitis, erectile dysfunction, and hyperprolactinemia. Radio-isotope scanning showed increased vascularity around the sphenoid bone. Treatment with intravenous bisphosphonates improved the active Paget's disease as indicated by declining alkaline phosphatase levels and the patient's erectile function while serum prolactin levels became normal and serum testosterone levels remained unchanged. Conclusion It is possible that hyperprolactinemia is unrecognised in other patients with Paget's disease of the skull. Normalizing elevated prolactin levels by using bisphosphonates in treating Paget's disease appears to be more appropriate than traditional treatment for hyperprolactinemia.

    Stem cells are defined by their capacity for both self-renewal and directed differentiation; thus,they represent great promise for regenerative medicine.Historically,stem cells have been categorized as either embryonic stem cells (ESCs) or adult stem cells (ASCs).It was previously believed that only ESCs hold the ability to differentiate into any cell type,whereas ASCs have the capacity to give rise only to cells of a given germ layer.More recently,however,numerous studies demonstrated the ability of ASCs to differentiate into cell types beyond their tissue origin.The aim of this review was to summarize contemporary evidence regarding stem cell availability,differentiation,and more specifically,the potential of these cells in the diagnosis and treatment of erectile dysfunction (ED) in both animal models and human research.We performed a search on PubMed for articles related to definition,Iocalisation and circulation of stem cells as well as the application of stem cells in both diagnosis and treatment of ED.Strong evidence supports the concept that stem cell therapy is potentially the next therapeutic approach for ED.To date,a large spectrum of stem cells,including bone marrow mesenchymal stem cells,adipose tissue-derived stem cells and muscle-derived stem cells,have been investigated for neural,vascular,endothelial or smooth muscle regeneration in animal models for ED.In addition,several subtypes of ASCs are localized in the penis,and circulating endogenous stem cells can be employed to predict the outcome of ED and ED-related cardiovascular diseases.

    2008-01-01

    Urinary incontinence (UI) and erectile dysfunction (ED) are both very prevalent conditions. Insertion of an artificial urinary sphincter (AUS) and penile prosthesis (PP) is an effective and proven method of treatment for both conditions. With advancing age, as well as with increasing populations of patients radically treated for prostate cancer, the occurrence of both conditions found in the same patient is increasing. The purpose of this article was to analyze the available evidence for simultaneous surgical management of male ED and UI using prosthetic devices.The existing literature pertaining to dual implantation of AUS and PP was reviewed. The concomitant insertion of the PP with the male perineal sling was also considered. Concurrent ED and UI are increasingly seen in the post radical prostatectomy population, who are often younger and less willing to suffer with these conditions. Insertion of an AUS and PP, either simultaneously or as a two-stage procedure, appears to be a safe, efficacious and long-lasting method of treatment. The improvements in design of both the AUS and PP as well as the development of the single transverse scrotal incision have made simultaneous insertion of these prostheses possible. Dual implantation of the PP and male sling looks promising in a selected population. In conclusion, the insertion of the AUS and PP for the treatment of concurrent UI and ED is safe and effective. Simultaneous insertion of these prostheses in the same patient offers potential advantages in operative and recovery time and is associated with high patient satisfaction. Combination therapy should therefore be included in the arsenal of treatment of these conditions.

    The landmark Massachusetts Male Ageing Study shed new light on the prevalence of erectile dysfunction (ED) and drew attention to ED as a disease of ageing.Over the years,ED has been linked to the development of cardiovascular disease (CVD) in some patients.There is clear evidence that ED and CVD share and have a similar risk factor profile.CVD is one of the most recognizable causes of mortality and early detection coupled with prevention of mortality from CVD has been the prime interest of many researchers.Consequently,there has been a multidisciplinary curiosity regarding the proposal to use ED as a marker for future CVD.In fact,there have been several proposals to use ED as a screening tool for future CVD.We performed a comprehensive search of two main databases-PubMed and Cochrane Library using a combination of keywords such as acute myocardial infarction,coronary artery disease (CAD) and ED.Journal articles from January 2000 to June 2011 were reviewed.We included all articles discussing the relationship between ED and CVD in the English language.All the relevant randomized controlled trials,cohort and retrospective studies,and review articles were included in our overall analysis in an attempt to answer the question whether all patients with ED should be clinically evaluated for CVD.The results showed a link between ED and the development of future CVD in some patients,but ED was not shown to be an independent risk predictor that is any better than the traditional Framingham risk factors.Screening for CVD may,however,be rewarding in younger oatients with severe ED and in patients with concurrent CVD risk factors.

  14. Frequency of autonomic neuropathy in patients with erectile dysfunction in diabetes mellitus

    International Nuclear Information System (INIS)

    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)

    DeLay, Kenneth J; Haney, Nora; Hellstrom, Wayne Jg

    2016-08-01

    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. PMID:27574592

    The objective of the present study was to evaluate therapeutic efficiency of transcranial magnetotherapy (TcMT) and electric stimulation (ES) included in the combined treatment of 143 patients with erectile dysfunction (ED) and abdominal obesity. The majority of the patients had waist circumference over 102 cm. An AMO-ATOS complex was used to stimulate the hypothalamic region and other brain structures. Transdermal myostimulation of the abdominal and femoral regions was achieved with a Miovolna device. It was shown that both TcM and ES improved lipid metabolism and erectile function; moreover, they exerted hypotensive and sedative action. Specifically, the testosterone level in the patients increased by a mean of 27% compared with the pre-treatment values while the number of patients complaining of erectile dysfunction decreased by 31%.

    Erectile dysfunction (ED) is a common yet complex condition. The authors report two cases of acromegaly presenting with ED and hypogonadotropic hypogonadism. Surgical cure of the acromegaly was associated with either an improvement or resolution of hypogonadotropic hypogonadism-associated ED. Active acromegaly should be considered in the differential diagnosis of ED presenting with supporting clinical features, particularly hypogonadotropic hypogonadism. PMID:26839523

    Functional imaging with positron emission tomography and single photon emission computed tomography is capable of visualizing subtle changes in physiological function in vivo. Erectile dysfunction (ED) diminishes quality of life for affected men and their partners. Identification of neural substrates may provide information regarding the pathophysiology of types of sexual dysfunction originating in the brain. The aim of this work is to verify the approaches of the nuclear medicine techniques in the evaluation of the erectile function/dysfunction. A search using the words ED and nuclear medicine, ED and scintigraphy, ED and SPECT and ED and PET was done in the PubMed. The number of citations in each subject was determined. Neuroimaging techniques offer insight into brain regions involved in sexual arousal and inhibition. To tackle problems such as hyposexual disorders or ED caused by brain disorders, it is crucial to understand how the human brain controls sexual arousal and penile erection. (author)

    Erectile dysfunction is a man's persistent or recurrent inability to achieve and maintain erection for a satisfactory sexual relationship. As diabetes is a major risk factor for erectile dysfunction, the prevalence of erectile dysfunction among diabetic men has been reported as 35% to 90%. This randomized, parallel-group, double-blind, placebo-controlled trial investigated the effects of a topical saffron (Crocus sativus L) gel on erectile dysfunction in diabetic men. Patients were randomly allocated to 2 equal groups (with 25 patients each). The intervention group was treated with topical saffron, and the control received a similar treatment with placebo. The 2 groups were assessed using the International Index of Erectile Function Questionnaire before the intervention and 1 month after the intervention. Compared to placebo, the prepared saffron gel could significantly improve erectile dysfunction in diabetic patients (P < .001). This preliminary evidence suggests that saffron can be considered as a treatment option for diabetic men with erectile dysfunction.

    Aim: To evaluate the efficacy and safety of transurethral application of alprostadil (MUSE.) for the treatment of erectile dysfunction in Indonesians. Methods: Twenty erectile dysfunction patients aged between 32 - 74 years old were recruited in this study. The inclusion criteria were as follows: 1 ) adult males 18 years or older with a subjective complaint or erectile dysfunction, 2) to provide written informed consent, 3) to agree not to use other forms of treatment for erectile dysfunction, 4) fulfill the screening laboratory values. Part 1, eligible patients were titrated in the clinic starting with a dose of 250 μg and proceed in a stepwise manner to 500μg and 1000μg on separate clinic visits until they identified a dose that produced a satisfactory response. The interval between each in-clinic titration was 2-3 days. Each in-clinic titration dose was evaluated at 15 min intervals over a one hour period for erection assessment, blood pressure and pulse. Part 2, patients used MUSE at home for three months at the dose identified during the inclinic titration. Monthly interim visits were required for patient follow-up and drug distribution. At the end of the study, patients had another laboratory (except testosterone, only assayed in screening procedure) and physical examination. Results: The etiology of erectile dysfunction was psychological in 5 patients and organic in 15 patients. The 65% of the patients achieved the erection scale of 4 or 5 either in the clinic or at home, 10% achieved the scale of 4 at home, but not in the clinic, and 25 % only achieved the scale of 2 or 3 with the highest dose of 1000μg either in the clinic or at home. No significant differences were found in biochemical examination before and after the study. The 60 % of the patients who achieved erection scale 4 or 5 continued to use MUSE until the end of the study, while 40 % of them complained of pain at the time of MUSE application, during erection and/or during intercourse.

    Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in rats. After these models were established, we administered apomorphine (via a sub-cutaneous injection in the neck) to observe changes in erectile function. Rats subjected to simple brachial plexus root avulsion or those subjected to brachial plexus root avulsion combined with spinal cord injury had signiifcantly fewer erections than those subjected to the sham operation. Expression of neuronal nitric oxide synthase did not change in brachial plexus root avulsion rats. However, neuronal nitric oxide synthase expression was signiifcantly decreased in brachial plexus root avulsion + spinal cord injury rats. These ifndings suggest that a decrease in neuronal nitric oxide synthase expression in the penis may play a role in erectile dysfunction caused by the combi-nation of brachial plexus root avulsion and spinal cord injury.

IIEF and PCDU were evaluated before and after the pistachio diet. In addition, plasma total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride were measured before and after dietary modifications from all subjects. Mean IIEF-15 score was 36 ± 7.5 before the diet and 54.2 ± 4.9 after the diet (P=0.001). Similarly, an increase in all five domains of IIEF was observed after the diet (Ppistachio diet were 35.5 ± 15.2 and 43.3 ± 12.4 cm s(-1), respectively (P=0.018). After the pistachio diet, TC and LDL levels decreased significantly, whereas HDL level increased (P=0.008, 0.007 and 0.001, respectively). We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED. Furthermore, the lipid parameters showed statistically significant improvements after this diet.

    We report on the case of a 52-year-old man who presented with a history of chronic neuropathic pain treated with intrathecal application of morphine for many years. In spite of significant dose escalation, considerable pain relief had not been achieved. Ziconotide had been tried but not only did it not provide pain relief, but it also caused severe side effects in this patient. A combination of morphine and clonidine was delivered by a programmable pump, slowly increasing the clonidine rate over several weeks. For ease of transition and minimization of hospitalization, which was a special concern to this patient, combining clonidine and morphine was chosen over monotherapy with hydromorphone, with both possibilities being described as equal alternatives in the literature. Considerable pain relief was achieved during week 2 at a clonidine dose of 0.040 mg/d, thereby decreasing the visual analog score (VAS) from 10 to 4. Yet, after developing erectile dysfunction and relative hypotension soon after beginning clonidine treatment, the patient decided not to continue with the combined application of morphine and clonidine. Treatment was therefore switched back to the former monotherapy with morphine. Thereafter, erectile dysfunction disappeared and blood pressure returned to habitual high levels. Although common in systemic application, erectile dysfunction caused by the intrathecal application of clonidine has not been described yet in the literature. In this patient, this rare side effect decisively impaired life quality, subjectively outweighing the considerable pain relief which could be achieved after formerly inefficacious treatment. Further and prospective investigation might be needed to estimate the connection of erectile dysfunction to intrathecal application of clonidine. PMID:22828698

    Our armamentarium for the treatment of erectile dysfunction has recently been expanded by addition of Viagra and the MUSE. However, their long-term results are still unknown. The insertion of a penile prosthesis is invasive, expensive, and irreversible, but under optimal condition provides an acceptable, definitive solution for erectile dysfunction. We evaluated our long-term results with penile prosthesis insertion (PPI). From 1987-1998, 57 patients underwent PPI in our department. Mean age was 55 years and the common causes of erectile dysfunction were atherosclerotic disease (23), radical pelvic surgery (15), and diabetes mellitus (14). Semirigid prostheses were inserted in 12 and inflatable prostheses in 45, including 42 single-component and 3 multi-component prostheses. Recently we interviewed these patients by telephone, using a standard questionnaire. Those not satisfied with the surgical results (83% of the living patients) were examined in our clinic. Mean follow-up was 53 months. In 37 (84%) the prosthesis was mechanically functional (rates after 1, 5 and 10 years were 87.8%, 80%, and 75%, respectively). In only 2 (2.5%) had serious complications led to prosthesis removal. All mechanical failures had occurred in those with inflatable prostheses after a mean of 48.5 months (range 4-113). At the time of the survey 68% were sexually active and 64% were satisfied with the surgical result. We conclude that PPI is safe treatment for erectile dysfunction. Although the rate of mechanically functioning prostheses decreases with time, modern multi-component prostheses may lead to better mechanical results.

    The studies evaluating the effect of smoking on olfaction reveals opposite results. In vitro and animal studies and epidemiological evidence from volunteers and patients, demonstrated the association between olfaction and erectile functions. In smoking man the reduction of olfactory acuity could adversely affect sexuality. The aim of the present study was to investigate the relationship between erectile dysfunction (ED) and olfactory dysfunction (OD) by comparing a group of healthy adult men with a group of smoking adult men. This prospective study involved 62 volunteers, who were recruited and divided into two groups; one consisted of 35 smoking adult men, and the other included 27 healthy non-smoking men. All participants in both groups were examined in detail for any condition with the potential to cause OD. They all had a normal genitourinary system suffered from no circulatory diseases, diabetes mellitus, hypertension, coronary artery disease nor hyperlipidemia; they had no history of medication affecting genitourinary system. Butanol threshold test and sniffin' stick® (Burghart, Wedel; Germany) screening test was used to asses olfactory functions in both groups. Participants' sexual desire was assessed using an International Index of Erectile Function (IIEF-5) scale. The means of sniffin' sticks scores, butanol threshold scores and IIEF-5 scores were statistically higher in non-smoking group. Butanol threshold scores and sniffin' sticks scores are correlated statistically with IIEF-5 in non-smoking and smoking groups. This study found an association between olfaction and erectile function in smoking and non-smoking men. As far as we know this study is the third published study to show the relationship olfactory and erectile function. In the future studies electrophysiological olfactory methods could be used to confirm in large cohorts the results obtained by the psychophysical approach. PMID:27037193

    During treatments with assisted reproductive technologies (ART), some men may have difficulties in producing spermatozoa on demand at the time of insemination, either for intrauterine insemination (IUI) or for in-vitro fertilization (IVF). This situation imposes tremendous stress on the couple and may cause cancellation of the treatment. Here we describe, for the first time, the use of sildenafil citrate (ViagraTM) for temporary erectile dysfunction in couples undergoing ART. The first case was a man who could not produce spermatozoa for the first IVF treatment after an exhausting trial for 12 h, despite the fact that he never had problems in providing sperm samples during previous IUI cycles. Using Viagra enabled him to provide spermatozoa, but the delay in oocyte insemination resulted in no embryonic development. This prompted us to be more alert to this option and to suggest the use of Viagra to men who had a history of erectile dysfunction during previous ART cycles. In these cases, the use of Viagra was planned in advance and it successfully solved any unpredictable erectile dysfunction on the day of insemination. Such cases emphasize the need to think in advance of this potential use of Viagra during ART. PMID:10402389

    This was a double-blind, placebo-controlled, flexible-dose study of the efficacy and safety of sildenafil in men with erectile dysfunction (ED) and clinically stable coronary artery disease (CAD). Patients were randomized to receive sildenafil or placebo for 12 weeks. Primary outcomes were questions 3 and 4 of the International Index of Erectile Function (IIEF). Secondary outcomes included the other IIEF questions and functional domains, the Life Satisfaction Checklist, the Erectile Dysfunction Inventory of Treatment Satisfaction, 2 global efficacy assessment questions, and intercourse success rate. By week 12, sildenafil-treated patients (n = 70) showed significant improvements on questions 3 and 4 compared with placebo-treated patients (n = 72; p <0.01). Larger percentages of sildenafil-treated patients reported improved erections (64%) and improved intercourse (65%) compared with placebo-treated patients (21% and 19%, respectively). Sildenafil-treated patients were highly satisfied with treatment and their sexual life compared with placebo-treated patients. Forty-seven percent of sildenafil- and 32% of placebo-treated patients experienced adverse events, including transient headache, hypertension, flushing, and dyspepsia. There were no serious drug-related cardiovascular effects. Thus, sildenafil is an effective and well-tolerated treatment for ED in men with CAD. Sildenafil was not associated with additional safety risks in this patient population. PMID:14715338

    Full Text Available Erectile dysfunction has been explored as a condition secondary to elevated prolactin; however, the mechanisms by which elevated prolactin levels cause erectile dysfunction have not yet been clearly established. We here present a patient with a history of prolactinoma who suffered from persistent erectile dysfunction despite testosterone supplementation and pharmacological and surgical treatment for the prolactinoma.  Patients who have had both prolactinemia and erectile dysfunction have been reported in the literature, but we find no report of a patient with persistent erectile dysfunction in the setting of testosterone supplementation and persistent hyperprolactinemia refractory to treatment. This case provides evidence supporting the idea that suppression of erectile function occurs in both the central and peripheral nervous systems independent of the hypothalamic-pituitary-gonadal axis.

    Full Text Available Age-related decline in erectile function is a noted phenomenon worldwide. A variety of medicinal plants have been identified as having strong aphrodisiac properties along with the ability to improve erectile functioning. Kaempferia Parviflora (KP has famous as a Thai Viagra and use it to increase male impotency. However, there is limited scientific evidence regarding the efficacy of this herb on this issue in aging healthy men. This study therefore investigated the effect of KP extract administration on erectile response of male elderly volunteers. Total 45 male healthy elderly volunteers will be divided into 3 separated groups including placebo and the different doses of ethanolic extracts of KP (25 and 90 mg once daily at a period of 2 months. The erectile function tests including the response latency time to visual erotic stimuli, size and length of penis both in flaccid and erection states were assessed after single administration, 1 and 2 months of treatment. In order to investigate the possible underlying mechanism, we also determined the alteration of testosterone, FSH and LH concentrations. KP at a dose of 90 mg day-1 treated group exhibited a significant enhanced all parameters after 1 and 2 months of treatment. Moreover, the penile length at erection states and the response latency to sexual erotic stimuli appeared to be the parameters that showed significant changes during the delay period. Unfortunately, our study failed to show the significant changes on hormones concentration. Our study clearly demonstrates that KP is a potential resource for the development of nutraceutical compound against aged related male erectile dysfunction.

    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.

    To investigate the effect of hyperhomocysteinaemia (HHCy) on penile erectile function in a rat model, a methionine-rich diet was used in which erectile function, the reproductive system, and nitric oxide synthase were characterized. The intracavernous pressure, apomorphine experiments, measurement of oxidative stress, hematoxylin and eosin staining, immunohistochemistry analysis, reverse transcription-polymerase chain reactions and measurement of endothelial nitric oxide synthase activity were utilized. Our results showed that erections in the middle-dose, high-dose, and interference (INF) groups were significantly lower than the control (P < 0.05). INF group, being fed with vitamins B and folic acid, demonstrated markedly improved penile erections compared with the middle-dose group (P < 0.05). HHCy-induced eNOS and phospho-eNOS protein expression was reduced and the antioxidant effect was markedly impaired. The data of the present data provide evidence that HHCy is a vascular risk factor for erectile dysfunction by impairing cavernosa endothelial nitric oxide synthase activity. Intake of vitamins B can alleviate this abnormality. PMID:27221552

    Erectile dysfunction (ED) is associated with clinical atherosclerosis and several atherosclerotic risk factors including smoking, hypertension, dyslipidemia, diabetes mellitus, obesity and sedentary lifestyle. Clinical atherosclerosis is also associated with these same risk factors and with biomarkers of inflammation, thrombosis, endothelial cell activation. We evaluated the cross-sectional association between the degree of ED and levels of atherosclerotic biomarkers. A subcohort of 988 US male health professionals between the ages 46 and 81 years as part of an ongoing epidemiologic study had atherosclerotic biomarkers measured from blood collected in 1994-1995. These same men had in 2000, been retrospectively asked about erectile function in 1995 and in 2000. Biennial questionnaires since 1986 assessed medical conditions, medications, smoking, physical activity, body mass index, alcohol intake. The retrospective assessment of erectile function in 2000 for 1995 in these 988 men ranged from very good - 28.2%, good - 25.1%, fair - 19.2%, poor - 13.6%, to very poor - 13.9%. Men with poor to very poor erectile function compared to men with good and very good erectile function had 2.9 the odds of having elevated Factor VII levels (P=0.03), 1.9 times the odds of having elevated vascular cell adhesion molecule (P=0.13) and 2.0 times the odds of having elevated intracellular adhesion molecule (P=0.06) and 2.1 times the odds of having elevated total cholesterol/high-density lipoprotein ratio (P=0.02) comparing the top to bottom quintiles for each atherosclerotic biomarker after multivariate adjustment. Lipoprotein(a), homocysteine, interleukin-6 and tumor necrosis factor receptor, C-reactive protein and fibrinogen were not associated with the degree of erectile function after adjustment. We conclude that selected biomarkers for endothelial function, thrombosis and dyslipidemia but not inflammation are associated with the degree of ED in this cross-sectional analysis. Future

Despite the increasing prevalence of erectile dysfunction (ED), there is reluctance among symptomatic patients to present to healthcare providers for appropriate advice and treatment. A number of Internet campaigns have been launched by the Irish healthcare media since 2007 aiming to provide easily accessible advice on ED. Novel online technologies appear to provide a useful tool for educating the general public on the symptoms of ED because there has been a significant increase in overall Internet search activity for this term since 2007.

    A number of circulating and imaging biomarkers are robustly associated with cardiovascular (CV) risk. The overall expectation from a biomarker in the erectile dysfunction (ED) setting is to enhance the optimal management of a man with this disorder but no clinical atherosclerosis. Evidence demonstrating that these biomarkers enhance risk prediction for individuals with ED is at this stage still limited for most of them. A better identification of the subsets of the ED population that require further risk stratification, as well as the initiation of randomized trials that will formally test the ability of biomarkers to predict CV risk, could make biomarker‑guided prevention an attainable goal.

    Full Text Available ABSTRACT The primary goal in the management strategy of a patient with ED would be to determine its etiology and cure it when possible, and not just to treat the symptoms alone. One of the new therapeutic strategies is the use of low intensity extracorporeal shockwave (LISW therapy. The mechanism of shockwave therapy is not completely clear. It is suggested that LISW induces neovascularization and improvement of cavernosal arterial flow which can lead to an improvement of erectile function by releasing NO, VEGF and PCNA. Materials and Methods: 31 patients between February and June 2013 with mild to severe ED and non-Phosphodiesterase 5 inhibitors responders were enrolled. Patients underwent four weekly treatment sessions. During each session 3600 shocks at 0.09mJ/ mm2 were given, 900 shocks at each anatomical area (right and left corpus cavernosum, right and left crus. Improvement of the erectile function was evaluated using the International Index of Erectile Function (IIEF-EF, the Sexual Encounter Profile (SEP diaries (SEP-Questions 2 and 3 and Global Assessment Questions (GAQ-Q1 and GAQ-Q2. Results: At 3-month follow-up IIEF-EF scores improved from 16.54±6.35 at baseline to 21.03±6.38. Patients answering ‘yes’ to the SEP-Q2 elevated from 61% to 89% and from 32% to 62% in the SEP-Q3. A statistically significant improvement was reported to the Global Assessment Questions (GAQ-Q1 and GAQ-Q2. Conclusion: In conclusion, we can affirm that LISW is a confirmed therapeutic approach to erectile dysfunction that definitely needs more long-term trials to be clarified and further verified.

    Full Text Available Erectile dysfunction (ED is a common disorder among aging males. However, most aging males refuse to seek medical help and believe that ED is an irreversible event in the aging process. The purpose of this study was to describe the current medical management of ED in aging males and to examine whether it is too late to treat this disorder in these elderly men. From 2007 to 2008, 4507 patients diagnosed with ED were gathered from 46 centers in China; 4241 completed the study, 3837 of whom were treated with sildenafil. The 3837 patients were divided into five groups based on age (group A: 20-30 years; group B: 31-40 years; group C: 41-50 years; group D: 51-60 years; and group E: >60 years. After comparing pre- and posttreatment International Index of Erectile Function-Erectile Function domain (IIEF-EF questionnaires, Erection Hardness Scale (EHS, and IIEF Q13 ("How satisfied have you been with your overall sex life?", we discovered that the aging males had worse erectile function, erection hardness, and sexual satisfaction than the younger males (P < 0.001. After treatment, the improvement rates in the IIEF-EF, EHS, and IIEF Q13 scores were 107.0%, 83.1%, and 116.5%, respectively. The magnitude of these changes demonstrated significant differences among groups (P < 0.001. Accordingly, aging males are likely to benefit more from medical treatment. We propose that aging males should be informed that age is not a limiting factor for medical ED management, and it is never too late to treat.

    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.

    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.

    Vacuum erection devices (VED) are becoming first-line therapies for erectile dysfunction and preservation (rehabilitation) of erectile function following treatment for prostate cancer. Currently, phosphodiesterase-5 inhibitors have limited efficacy in elderly patients or patients with moderate to severe diabetes, hypertension, and coronary artery disease. Alternative therapies, such as VED, have emerged as a primary option for patients refractory to oral therapy. VED has also been successfully used in combination treatment with oral therapy and penile injections. More recently, there has been interest in the use of VED in early intervention protocols to encourage corporeal rehabilitation and prevention of post-radical prostatectomy venoocclusive dysfunction. This is evident by the preservation of penile length and girth seen with the early use of the VED following radical prostatectomy. There are ongoing studies to help preserve penile length and girth with early use of VED following prostate brachytherapy and external beam radiation for prostate cancer. Recently, there has also been interest in VED to help maintain penile length following surgical correction of Peyronie's disease and to increase penile size before implantation of the penile prosthesis.

Therefore, cardiovascular safety and potential drug interactions are two of the major concerns when using PDE-5 inhibitors in these patients. The PDE-5 inhibitor, vardenafil, is characterized by a rapid onset of action, increased duration of erection, high rates of first-dose success and reliable efficacy that can be maintained with continued use. In both clinical trials and real-life observational studies, vardenafil has demonstrated a favorable efficacy and safety profile in men with ED, including those with associated underlying conditions such as diabetes, hypertension and dyslipidemia. Importantly, the concomitant use of medication for these conditions is not associated with any noteworthy changes in the efficacy and safety of vardenafil. The evidence presented in this review supports the use of vardenafil as a first-line treatment for men with ED, including those with underlying conditions.Keywords: vardenafil, erectile dysfunction, efficacy, safety, underlying conditions

Being systemic, it might be possible to evaluate the extent of atherosclerosis from retinal vascular findings. We investigated the possible correlation between penile cavernosal artery blood flow and retinal vascular findings in patients with arteriogenic ED.Patients and methods: Sixty patients with ED were divided according to the peak systolic velocity (PSV in their penile cavernosal arteries into two groups; Group A included 30 patients with PSV less than 25 cm/sec, and Group B included 30 patients with PSV more than 35 cm/sec. Blood flow in the penile cavernosal artery was measured with color Doppler ultrasonography. All patients were assessed by ocular fundus examination under amydriatic conditions to evaluate retinal vascular atherosclerotic changes using Hyman’s classification.Results: Evidence of retinal vascular atherosclerotic changes was found in 19 patients (63.3% in Group A and in 10 patients (33.3% in Group B.Conclusions: Our study confirms the possibility of predicting penile arterial vascular status in patients with ED from their retinal vascular findings by using amydriatic simple, practical funduscopy.Keywords: erectile dysfunction, atherosclerosis, retinal vascular atherosclerosis

    Erectile dysfunction (ED) commonly results from endothelial dysfunction of the systemic vasculature. Although phosphodiesterase type 5 (PDE-5) inhibitors are effective at treating most cases of ED, they must be taken routinely and are ineffectual for a meaningful number of men. In recent years gene and stem cell-based therapies targeted at the penile endothelium have been gaining momentum in preclinical studies. These early studies reveal that gene and stem cell-based therapies may be both enduring and efficacious, and may eventually lead to a cure for ED. The following review will highlight our current understanding of endothelial-specific gene and stem cell-based therapies performed to date in a number of experimental animal models.

    To evaluate the effect of statins for erectile dysfunction (ED), a systematic review of the literature was conducted in the Cochrane Library, Embase and PubMed from the inception of each database to June 2013. Only randomized controlled trials (RCTs) comparing treatment for ED with statins were identiifed. Placebo RCTs with the International Index of Erectile Function (IIEF) as the outcome measure were eligible for meta-analysis. A total of seven RCTs including two statins with a total of 586 patients strictly met our criteria for systematic review and ifve of them qualiifed for the meta-analysis. A meta-analysis using a random effects model showed that statins were associated with a signiifcant increase in IIEF-5 scores (mean difference (MD):3.27;95%conifdential interval (CI):1.51 to 5.02;P<0.01) and an overall improvement of lipid proifles including total cholesterol (MD:-1.08;95%CI:-1.68 to-0.48;P<0.01), low-density lipoprotein (LDL) cholesterol (MD:-1.43;95%CI:-2.07 to-0.79;P<0.01), high-density lipoprotein (HDL) cholesterol (MD:0.24;95%CI:0.13 to 0.35;P<0.01) and triglycerides (TGs) (MD:-0.55;95%CI:-0.61 to -0.48;P< 0.01). In summary, our study revealed positive consequences of these lipid-lowering drugs on erectile function, especially for nonresponders to phosphodiesterase type 5 inhibitors (PDE5Is). However, it has been reported that statin therapy may reduce levels of testosterone and aggravate symptoms of ED. Therefore, larger, well-designed RCTs are needed to investigate the double-edged role of statins in the treatment of ED.

    The aim of this study was to investigate whether the omega-3 fatty acids help to improve erectile function in an atherosclerosis-induced erectile dysfunction rat model. A total of 20 male Sprague-Dawley rats at age 8 weeks were divided into three groups: Control group (n = 6, untreated sham operated rats), Pathologic group (n = 7, untreated rats with chronic pelvic ischemia [CPI]), and Treatment group (n = 7, CPI rats treated with omega-3 fatty acids). For the in vivo study, electrical stimulation of the cavernosal nerve was performed and erectile function was measured in all groups. Immunohistochemical antibody staining was performed for transforming growth factor beta-1 (TGF-β1), endothelial nitric oxide synthase (eNOS), and hypoxia inducible factor 1-alpha (HIF-1α). In vivo measurement of erectile function in the Pathologic group showed significantly lower values than those in the Control group, whereas the Treatment group showed significantly improved values in comparison with those in the Pathologic group. The results of western blot analysis revealed that systemically administered omega-3 fatty acids ameliorated the cavernosal molecular environment. Our study suggests that omega-3 fatty acids improve intracavernosal pressure and have a beneficial role against pathophysiological consequences such as fibrosis or hypoxic damage on a CPI rat model, which represents a structural erectile dysfunction model.

    This study assessed the effect of KCNMA1 transfected bone marrow-mesenchymal stem cells (BM-MSCs) on the improvement of erectile function in diabetic rats. Sixty male Sprague-Dawley rats were injected with streptozotocin (STZ) and screened with apomorphine (APO) to establish diabetes mellitus-induced erectile dysfunction (DMED). DMED rats were randomly divided into four groups: rats in each group underwent intracavernous injection with either phosphate buffer solution (DMED+PBS), nontransfected MSCs (DMED+MSCs), empty vector transfected MSCs (DMED+null-MSCs) or KCNMA1 transfected MSCs (DMED+KCNMA1-MSCs). Before injection, high levels of KCNMA1 expression were confirmed in KCNMA1-MSCs using RT-PCR and Western blotting. The lentivirus transfected MSCs maintained their potential for multidirectional differentiation. Four weeks after injection, erectile function was ascertained by measuring intracavernous pressure (ICP). Penile tissues were collected for immunohistochemical analysis. The expression of KCNMA1 in the corpus cavernosum was increased, and the DMED+KCNMA1-MSCs group displayed a significant improvement of erectile function. We concluded that KCNMA1 was able to enhance the positive effect of MSCs in the treatment of diabetes-associated erectile dysfunction.

    The sinusoid anatomy of the penis is complex and requires complicated interaction between smooth muscle and endothelium in order to maintain homeostasis in the adult. The morphogen, Sonic hedgehog (Shh), is a crucial regulator of these processes, along with its down stream targets patched (Ptc), Hox, bone morphogenetic proteins (BMP's), vascular endothelial growth factor (VEGF) and nitric oxide synthase (NOS). Shh is critical for patterning and establishing tissue identity of the penis during embryonic development, is a crucial regulator of penile postnatal differentiation of the sinusoid morphology of the corpora cavernosa, and plays a fundamental role in maintaining sinusoidal structures pertinent to erectile function in the adult rat. Shh and its targets are active in human penes, and decreased in human diabetic penes in parallel with observations in the rat, thus lending clinical significance to the role of abnormal Shh signaling in erectile dysfunction (ED). Application of exogenous Shh protein to rat corpora cavernosa, induces VEGF and NOS proteins, suggesting a potential mechanism through which decreased Shh protein can cause ED. The studies outlined in this review provide in depth analysis of the Shh pathway and signal transduction, its role in penile development, how Shh signaling is altered in a rat model of ED and neuropathy, how abnormal Shh signaling can cause ED, and the clinical significance of the Shh pathway to human ED. These studies will provide valuable insight, at the molecular level, into understanding the mechanisms that under lie ED and lead to new treatment strategies for diabetic impotence. PMID:16378507

    The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a cohort of Italian hypertensive men and the association with clinical and biochemical data. The study involved 270 consecutive hypertensive subjects aged 40-70 years evaluated in Italian Hypertension Centers of six hospitals from Liguria and Piedmont. ED was assessed through the self-administered questionnaire of the International Index of Erectile Function. Clinical history with ongoing drug treatment, various clinical parameters, biochemical data and evidence about the presence of subclinical target organ damage was collected. Twenty-seven subjects refused to answer the questionnaire (10%). Among the 243 remained subjects, 123 presented ED (50.6%). ED was highly related to age, systolic blood pressure, pulse pressure, smoking status, statin therapy and kidney function. The addition of a thiazide diuretic to an inhibitor of the renin-angiotensin system significantly increased the prevalence of ED. The prevalence of ED increased in relation with the number of hypotensive drug classes taken by the patients. ED was highly prevalent in this cohort of Italian hypertensive subjects and was associated with other cardiovascular risk factors, such as age, smoking status and kidney function. The role of ED as an early marker of cardiovascular disease is discussed. PMID:26418513

    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 availability of adequate treatment for erectile dysfunction (ED) triggers studies into the prevalence of ED in the general population. Yet, previous studies showed different prevalence estimates partly due to differences in patient selection, in (unclear) definitions of ED and in assessment. ENIGMA has been designed to study the prevalence of ED in the general population of The Netherlands, using the WHO definition with a description of the way of assessment. In all, 5721 mail surveys were sent to all men, aged 18 y and older in 12 general practices in The Netherlands. A total of 5601 were included in the study and 2117 (38%) were completed. A total of 38% of the men reported to have ever had some kind of erectile problem. The prevalence of ED was 17% (6% mild, 4% moderate and 7% complete). Age, diabetes, cardiovascular diseases, penile disorders, irradiation in the pelvic region, relational problems, fear for failure, surmenage, medication use and regular consumption of alcohol were independently related to ED. Men with ED were less content with their (sexual) life and had less confidence in sexual performance. Presence of ED was negatively related to affected happiness in life. ED is commonly found in men and is related to age, medication, comorbidity and lifestyle factors. Men with ED perceive a lower quality of (sex)life. Doctors should be aware of the presence of ED and its consequences in patients. PMID:14961062

    Anaissie, James; Hellstrom, Wayne JG

    2016-01-01

    Erectile dysfunction (ED) is a common and debilitating disorder seen in over 50% of men older than 70 years. Oral phosphodiesterase type 5 (PDE5) inhibitors are the mainstay of treatment for ED, but cannot be used by a significant subset of patients due to systemic side effects and drug–drug interactions. Second-line therapy may include intracavernosal therapies, but are associated with poor compliance due to their invasive nature. Alprostadil has a mechanism of action different from that of PDE5 inhibitors. Clinical trials have shown topical alprostadil cream to be effective, increasing the erectile function (EF) score of the International Index of EF by up to 13 points from baseline. It has also proven to be safe and well tolerated, with mild-to-moderate and transient treatment-related adverse events that are generally localized to the application site. Topical alprostadil cream is a safe and effective second-line therapy for ED, indicated for those who cannot tolerate, or are not satisfied with, oral PDE5 inhibitor therapy. PMID:27536559

    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.

    There are various treatment modalities for erectile dysfunction with different success and satisfaction rates. We aim to compare patient satisfaction with tadalafil, intracavernosal injection, and penile prosthesis implantation in patients with erectile dysfunction. The records of 3448 men with erectile dysfunction were evaluated retrospectively. A total of 356 men with organic erectile dysfunction were enrolled into this study. Of these patients, 132 (37%) received tadalafil 20 mg twice a week for 12 weeks, 106 (30%) patients received tadalafil 5 mg once-daily for 12 weeks, 96 (27%) patients used intracavernosal injection therapy (Bi-mix; papaverine and phentolamine). Moreover, 22 patients underwent penile prosthesis implantation. Patient and partner satisfaction were assessed with International Index of Erectile Function (IIEF) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire. Patients' mean age was 52.4 ± 25.76 (32-71). The etiology of erectile dysfunction was chronic systemic diseases in 133 (44%) and radical prostatectomy in 121 patients (40%). The mean IIEF-5 scores improvement after the treatment was higher in penile prosthesis implantation group (12.4 ± 1.3) compared with tadalafil 5 mg (6.7 ± 1.5) (p prosthesis implantation group (78.2 ± 11.3) compared with intracavernosal injection (60.3 ± 6.3), tadalafil 5 mg (72.5 ± 4.5), and tadalafil 20 mg 70.7 ± 3.4 groups (p prosthesis implantation group, 50.2 ± 1.5 in intracavernosal injection group, 62.9 ± 7.8 in tadalafil 5 mg, and 61.3 ± 5.3 in tadalafil 20 mg group (p prosthesis implantation seem to be more satisfied compared with tadalafil treatment and intracavernosal injection. Future clinical trials are warranted to confirm our results. PMID:27368423

    Phosphodiesterase type 5 (PDE5) inhibitors are the most commonly used treatment for erectile dysfunction (ED). Since the launch of sildenafil, several drugs-including mirodenafil, sildenafil citrate (sildenafil), tadalafil, vardenafil HCL (vardenafil), udenafil, and avanafil-have become available. Mirodenafil is a newly developed pyrrolopyrimidinone compound, which is a potent, reversible, and selective oral PDE5 inhibitor. Mirodenafil was launched in Korea in 2007, and an orally disintegrating film of mirodenafil was developed in 2011 for benefitting patients having difficulty in swallowing tablets. This study aimed to review the pharmacokinetic characteristic profile of mirodenafil and report evidence on its efficacy in the case of ED. In addition, we reviewed randomized controlled studies of mirodenafil's daily administration and efficacy for lower urinary tract symptoms. PMID:24872948

    2008-01-01

    Advances in the neurobiology of growth factors, neural development, and prevention of cell death have resulted in a heightened clinical interest for the development of protective and regenerative neuromodulatory strategies for the cavernous nerves (CNs), as therapies for prostate cancer and other pelvic malignancies often result in neuronal damage and debilitating loss of sexual function. Nitric oxide released from the axonal end plates of these nerves within the corpora cavernosa causes relaxation of smooth muscle, initiating the haemodynamic changes of penile erection as well as contributing to maintained tumescence; the loss of CN function is primarily responsible for the development of erectile dysfunction (ED) after pelvic surgery and serves as the primary target for potential neuroprotective or regenerative strategies. Evidence from pre-clinical studies for select neuromodulatory approaches is reviewed, including neurotrophins, glial cell line-derived neurotrophic factors (GDNF), bone morphogenic proteins, immunophilin ligands,erythropoetin (EPO), and stem cells.

    Full Text Available About 150 million men worldwide and about 50% of men aged 40-88 y.o. in outpatient practice suffer from erectile dysfunction (ED. There is a linear relation between the age and ED rate. The main reason of ED in the majority of men (about 80% of patients is cardiovascular diseases (atherosclerosis, hypertension, diabetes mellitus, as well as certain risk factors (smoking, alcohol abuse, physical inactivity etc.. The problem of ED in cardiac outpatients and modern pharmacotherapy is discussed. The phosphodiesterase-5 (PDE5 inhibitors increase the relaxing effect of nitric oxide and increase cyclic GMP levels during sexual arousal. It results in increase of cavernosum blood flow, contributing to the physiological erection. Three PDE5 inhibitors (sildenafil, tadalafil, vardenafil are used in clinical practice nowadays.

    Vascular disease is the most common etiology of erectile dysfunction (ED). Men with ED are at a 65% increased relative risk of developing coronary heart disease and a 43% increased risk of stroke within 10 years. Vascular disease is associated with cognitive impairment; ED—an overt manifestation of vascular dysfunction—could also signal early compromised cognition. We sought to determine whether cognitive differences existed between men with ED and healthy peers. Our sample consisted of 651 men (ages 51–60 years) from the Vietnam Era Twin Study of Aging. ED was associated with poorer cognitive performance, particularly on attention–executive–psychomotor speed tasks. ED remained significantly associated with cognition after inclusion of other cardiovascular risk factors (including hypertension, high cholesterol, body mass index, and smoking). These findings underscore the importance of further study of ED as a predictor of cognitive and cardiovascular health. PMID:24660805

    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

    As chronic illnesses and chronic pain are related to erectile dysfunction (ED), migraine as a prevalent chronic disorder affecting lots of people all over the world may negatively affect quality of life as well as sexual function. However, a large-scale population-based study of erectile dysfunction and other different comorbidities in patients with migraine is quite limited. This cohort longitudinal study aimed to estimate the association between migraine and ED using a nationwide population-based database in Taiwan.The data used for this cohort study were retrieved from the Longitudinal Health Insurance Database 2000 in Taiwan. We identified 5015 patients with migraine and frequency matched 20,060 controls without migraine from 2000 to 2011. The occurrence of ED was followed up until the end of 2011. We used Cox proportional hazard regression models to analyze the risks of ED.The overall incidence of ED was 1.78-fold greater in the migraine cohort than in the comparison cohort (23.3 vs 10.5 per 10,000 person-years; 95% confidence interval [CI] = 1.31-2.41). Furthermore, patients with migraine were 1.75-fold more likely to develop organic ED (95% CI = 1.27-2.41) than were the comparison cohort. The migraine patients with anxiety had a 3.6-fold higher HR of having been diagnosed with ED than the comparison cohort without anxiety (95% CI, 2.10-6.18).The results support that patients with migraine have a higher incidence of being diagnosed with ED, particularly in the patient with the comorbidity of anxiety.

    2008-01-01

    The present paper serves as a review of the associations between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), with a focus on common and combined pathways for treatment. LUTS and ED are common conditions seen in general urologic practice. Research has started to establish epidemiologic and pathophysiologic links between the two conditions and a strong association confirmed across multiple studies. Men seeking care for one condition should always be interviewed for complaints of the other condition. Proposed common pathways include α-1 adrenergic receptor imbalance, Rho-kinase overactivity, endothelial cell dysfunction and atherosclerosis-induced ischemia. Medical therapy has replaced surgery as the first-line treatment for LUTS in most patients, with the incorporation of α-adrenergic receptor antagonists (α-ARAs) and 5-α-reductase inhibitors (5-ARIs) into everyday practice. Treatment with α-ARAs contributes to some improvement in ED, whereas use of 5-ARIs results in worsened sexual function in some patients. Phosphodiesterase-5 (PDE-5) inhibitors have revolutionized the treatment of ED with a simple oral regimen, and new insights demonstrate a benefit of combined use of PDE-5 inhibitors and α-ARAs. The mechanisms of action of these medications support these observed benefits, and they are being studied in the basic science and clinical settings. In addition, novel mechanisms for therapy have been proposed based on clinical and research observations. The minimally invasive and surgical treatments for LUTS are known to have adverse effects on ejaculatory function, while their effects on erectile function are still debated. Much remains to be investigated, but it is clear that the associations between LUTS and ED lay the foundation for future therapies and possible preventative strategies.

    Introduction Bilateral cavernous nerve injury (BCNI) causes profound penile changes such as apoptosis and fibrosis leading to erectile dysfunction (ED). Histone deacetylase (HDAC) has been implicated in chronic fibrotic diseases. Aims This study will characterize the molecular changes in penile HDAC after BCNI and determine if HDAC inhibition can prevent BCNI-induced ED and penile fibrosis. Methods Five groups of rats (8–10 wks, n=10/group) were utilized: 1) sham, 2&3) BCNI 14 and 30 days following injury, and 4&5) BCNI treated with HDAC inhibitor valproic acid (VPA 250mg/kg; 14 and 30 days). All groups underwent cavernous nerve stimulation (CNS) to determine intracavernosal pressure (ICP). Penile HDAC3, HDAC4, fibronectin, and transforming growth factor-β1 (TGF-β1) protein expression (Western blot) were assessed. Trichrome staining and the fractional area of fibrosis were determined in penes from each group. Cavernous smooth muscle content was assessed by immunofluorescence to alpha smooth muscle actin (α-SMA) antibodies. Main Outcome Measures ICP; HDAC3, HDAC4, fibronectin and TGF-β1 protein expression; penile fibrosis; penile α-SMA content. Results There was a voltage-dependent decline (p<0.05) in ICP to CNS 14 and 30 days after BCNI. Penile HDAC3, HDAC4, and fibronectin were significantly increased (P<0.05) 14 days after BCNI. There was a slight increase in TGF-β1 protein expression after BCNI. Histological analysis showed increased (P<0.05) corporal fibrosis after BCNI at both time points. VPA treatment decreased (P<0.05) penile HDAC3, HDAC4, and fibronectin protein expression as well as corporal fibrosis. There was no change in penile α-SMA between all groups. Furthermore, VPA-treated BCNI rats had improved erectile responses to CNS (P<0.05). Conclusion HDAC-induced pathological signaling in response to BCNI contributes to penile vascular dysfunction after BCNI. Pharmacological inhibition of HDAC prevents penile fibrosis, normalizes fibronectin

    Epidemiologic studies have shown that aging accounts significantly for the prevalence of erectile dysfunction (ED). The pathophysiology of ED during aging and its underlying molecular mechanisms are largely unknown. We hypothesized that increased RhoA/Rho-kinase signaling is a major factor in the pathogenesis of age-associated ED and the mechanism involves increased penile smooth muscle contractility through inhibition of myosin light chain phosphatase. Male Fischer 344 young (4 month old) and aged (20-22 month old) rats underwent erectile function testing in vivo by measuring intracavernosal pressure (ICP) and mean arterial blood pressure (MAP) upon electrical stimulation of the cavernous nerve. The data demonstrated that erectile function was significantly lower in aged rats than that in young rats at all voltages tested (Ppenes by 95 +/- 15 and 56 +/- 8% (Ppenes of aged and young rats for 7 days markedly improved erectile function in aged rats when compared with that in young rats (Ppenes receiving AAV vehicle treatment was twofold greater than that in young rat penes receiving AAV vehicle treatment, while it was reduced to a level similar to that in young rat penes after gene therapy of T19NRhoA (P<0.05). Taken together, these data suggest that impaired erectile function during the aging process involves increased RhoA/Rho-kinase signaling, and this pathway may be exploited for the treatment of age-associated ED.

    Korean ginseng and mountain ginseng (Panax ginseng CA Meyer) are important traditional herbal plants whose ginsenosides are generally accepted as serving to improve sexual functions, such as penile erection. We investigated the effects of tissue-cultured mountain ginseng extract (TMGE) on male patients with erectile dysfunction (ED). A double-blind, placebo-controlled study was conducted with 143 patients experiencing ED. Over the course of 8 weeks, one group took 1 000 mg of TMGE twice a day, and the other group took 1 000 mg of placebo twice a day. The effects of the TMGE and the placebo were analyzed using the Korean version of the International Index of Erectile Function (IIEF) questionnaire. A total of 86 patients completed 8 weeks of treatment. The scores on the five domains of the IIEF after medication were significantly higher than the baseline scores in the group treated with TMGE (P0.05). Erectile function and overall satisfaction scores after medication were significantly higher in the TMGE group than in the placebo group (P<0.05). Erectile function of patients in the TMGE-treated group significantly improved, suggesting that TMGE could be utilized for improving erectile function in male patients.

    Objective To investigate the presence, location and functional role of TMEM16A/anotamin-1 (Ano1) calcium-activated chloride channel (CaCC) in the penile of rats with diabetic erectile dysfunction. Methods Eight-week-old male Sprague-Dawley (SD) rats were administrated streptozotocin (diabetic) or citrate buffer (control) randomly. Erectile function was measured by cavernous nerve electrostimulation at 12th week after diabetes was induced. The effect of Ano1 specific inhibitor—T16Ainh-A01 on intracavernous pressure (ICP) was evaluated. Then the penile tissues were harvested for molecular exploration. Real-time PCR and Western Blotting were used to assess the expression of Ano1 in penile tissues. Immunofluorescent labelling of penile tissue allowed localization of Ano1. Cavernous smooth muscle cell (CSMC) was cultured in high glucose medium. The change of Ano1 was measured using Western Blotting. The proliferation of CSMC was evaluated by cell counting kit-8 (CCK-8). Results Erectile function was impaired in diabetic rats. The expression of Ano1 was increased in rats with diabetic erectile dysfunction at mRNA and protein levels. Immunofluorescent labelling revealed the presence of Ano1 mainly in cavernous smooth muscle cells. The inhibition of Ano1 increased the ICP of DED rats. High glucose in vitro enhanced the proliferation of CSMC and the expression level of Ano1. Conclusions Ano1 is expressed in rat penile tissue and is increased with diabetes mellitus. The inhibition of Ano1 increased the ICP of DED rats. The alerted Ano1 may be associated with diabetic erectile dysfunction. It is a potential therapy target for ED in the future.

    Introduction 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. Aims 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. Methods 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. Results 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. Conclusions 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

    Objective To investigate the mechanism of androgen replacement therapy (ART) improving erectile dysfunction (ED) in castrated rats. Methods We randomly divided 40 8-week-old healthy male SD rats into 4 groups: group A was the control, and rats of the group B, C and D were castrated, then rats in the groups C and D were treated with different concentrations of testosterone undecanoate orally every day (C: 10 mg/kg, D: 20 mg/kg), while other groups with 0.9% NS instead. 8weeks’ treatment later, we determined the level of serum testosterone and assessed the erectile function of rats. Western blot, immunohistochemistry were performed to detect the level of target proteins. Results (I) The level of serum testosterone and erectile function (Max ICP/MAP): group Bwas significantly lower than group A, C and D, and group D was higher compared with group C; (II) effect of castration and ART on endothelial cells and androgen receptor (AR)/vascular endothelial growth factor (VEGF)/cyclin A pathway: the expression of CD31, vWF and AR/VEGF/cyclin A in group B were lower than group A, C and D, and group D was higher compared with group C; (III) effect of castration and ART on corpus cavernosum smooth muscle cells (CCSMCs) and TGF-β/S1P2/RhoA/ROCK pathway: the expression of α-sma in group B were lower than group A, C and D, and group D was higher compared with group C; while the expression of TGF-β/S1P2/RhoA/ROCK1 were higher in group B than group A, C and D, and group D was lower compared with group C. Conclusions ART can improve ED in castrated rats through promoting the proliferation of corpus cavernosum endothelial cells by activating AR/VEGF/cyclin A pathway; decreasing the contraction of CCSMCs and corporal fibrosis by inhibiting TGF-β/S1P2/RhoA/ROCK pathway, which provides reference for revealing the mechanism of ART treating ED associated late-onset hypogonadism.

    Erectile dysfunction (ED) is a common disorder that can jeopardize quality of life and the partnership of patients and their sexual partners. The advent of oral phosphodiesterase type 5 inhibitors (PDE5Is) has revolutionized a treatment for ED, and they are recognized as the first-line therapy for ED, regardless of its etiology. Mirodenafil, a second-generation PDE5I, has biochemical profiles such as high affinity for PDE5 and high selectivity for PDE5 over other PDE isoforms, compared to other existing PDE5Is such as sildenafil, vardenafil and tadalafil. Available evidence has suggested that doses of 50 and 100 mg mirodenafil effectively improve ED [with improvements in the erectile function domain of the International Index of Erectile Function (IIEF-EF) scores, positive responses to questions 2 of the Sexual Encounter Profiles (SEP2) and questions 3 of the Sexual Encounter Profiles (SEP3): 7.6-11.6 points, 27.72-38.98% and 44.20-67.33%, respectively] in a broad range of patient populations with ED of a variety of underlying etiologies, severities and ages, without any serious treatment-related adverse effects. In the treatment of diabetic ED, a traditionally difficult-to-treat population, 100 mg mirodenafil has been reported to offer favorable efficacy (with improvements in the IIEF-EF scores, and positive responses to the SEP2 and the SEP3: 9.3 points, 36.1% and 61.8%, respectively) and tolerability (mild adverse effects of less than 19.6%), which are comparable with results from clinical studies on other PDE5Is. Mirodenafil appears to be effective, safe and well tolerated in men with both ED and hypertension or lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) who are taking concomitant antihypertensive medications or α1-blockers. Furthermore, recent evidence has indicated that mirodenafil may be a potential option for chronic dosing in the treatment of ED despite its short half-life (T 1/2). Most of the available clinical studies have

    Full Text Available Abstract Background Paradoxical sleep deprivation (PSD associated with cocaine has been shown to enhance genital reflexes (penile erection-PE and ejaculation-EJ in Wistar rats. Since hypertension predisposes males to erectile dysfunction, the aim of the present study was to investigate the effects of PSD on genital reflexes in the spontaneously hypertensive rat (SHR compared to the Wistar strain. We also extended our study to examine how PSD affect steroid hormone concentrations involved in genital events in both experimental models. Methods The first experiment investigated the effects of PSD on genital reflexes of Wistar and SHR rats challenged by saline and cocaine (n = 10/group. To further examine the impact of the PSD on concentrations of sexual hormones, we performed a hormonal analysis of testosterone and progesterone in the Wistar and in SHR strains. Since after PSD progesterone concentrations decreased in the SHR compared to the Wistar PSD group we extended our study by investigating whether progesterone (25 mg/kg or 50 mg/kg or testosterone (0.5 mg/kg or 1.0 mg/kg administration during PSD would have a facilitator effect on the occurrence of genital reflexes in this hypertensive strain. Results A 4-day period of PSD induced PE in 50% of the Wistar rats against 10% for the SHR. These genital reflexes was potentiated by cocaine in Wistar rats whereas this scenario did not promote significant enhancement in PE and EJ in hypertensive rats, and the percentage of SHR displaying genital reflexes still figured significantly lower than that of the Wistar strain. As for hormone concentrations, both sleep-deprived Wistar and SHR showed lower testosterone concentrations than their respective controls. Sleep deprivation promoted an increase in concentrations of progesterone in Wistar rats, whereas no significant alterations were found after PSD in the SHR strain, which did not present enhancement in erectile responses. In order to explore the role

    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

    Electromyography (EMG) of the corpora cavernosa (CC-EMG) is able to record the activity of the erectile tissue during erection, and thus has been used as a diagnostic technique in patients with erectile dysfunction (ED). The present study examines the usefulness of the technique in the diagnosis of arterial ED. A cross-sectional study was made of 35 males with a mean age of 48.5 years (s.d. 11.34), referred to our center with ED for >1 year. The patients were subjected to CC-EMG and a penile Doppler ultrasound study following the injection of 20 μg of prostaglandin E1 (PGE1). The patients were divided into three groups according to their response to the intracavernous injection of PGE1: Group 1 (adequate erection and reduction/suppression of EMG activity); Group 2 (insufficient erection and persistence of EMG activity); and Group 3 (insufficient erection and reduction/suppression of EMG activity). Patient classification according to response to the intracavernous injection of PGE1 was as follows: Group 1: six patients (17%), Group 2: 18 patients (51%), and Group 3: 11 patients (31%). Patients diagnosed with arterial insufficiency according to Doppler ultrasound (systolic arterial peak velocity EMG activity showed a sensitivity of 66.7% (confidence interval between 50 and 84%) and a specificity of 92.9% (confidence interval between 84 and 100%) in the diagnosis of arterial ED. Owing to the high specificity of CC-EMG response to the injection of PGE1, this test is considered useful as a screening technique in the diagnosis of arterial ED.

    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. .

  8. Masculinity and emotion in Mexican men's understandings of erectile dysfunction aetiology and treatment.

    This paper investigates the role that emotions related to local gender norms play in urban Mexican men's understandings of erectile dysfunction (ED) aetiology and drug treatment by analysing semi-structured interviews with 28 male urology patients. Analysing narrative data from our interviews, the paper examines how these men drew differently from locally intelligible ways of understanding health and masculinity to develop context-specific understandings of causes and potential treatment outcomes. Study participants' feelings of success or failure in life areas relating to the performance of 'responsible' masculinity, especially work and romance, strongly influenced understandings of ED aetiology and goals for drug treatment. Those who felt successful at being men collaborated with loved ones to adopt purely biological understandings of ED causation, while those who expressed negative emotions about their performances of masculinity viewed these feelings, as well as the structural and interpersonal problems that caused them, as key causes and consequences of dysfunction. I discuss how these different emotional experiences led to different ways of using medication, and the relevance of these findings for clinical practice.

    Full Text Available BACKGROUND: Erectile dysfunction is an emerging risk marker for future cardiovascular disease (CVD events; however, evidence on dose response and specific CVD outcomes is limited. This study investigates the relationship between severity of erectile dysfunction and specific CVD outcomes. METHODS AND FINDINGS: We conducted a prospective population-based Australian study (the 45 and Up Study linking questionnaire data from 2006-2009 with hospitalisation and death data to 30 June and 31 Dec 2010 respectively for 95,038 men aged ≥45 y. Cox proportional hazards models were used to examine the relationship of reported severity of erectile dysfunction to all-cause mortality and first CVD-related hospitalisation since baseline in men with and without previous CVD, adjusting for age, smoking, alcohol consumption, marital status, income, education, physical activity, body mass index, diabetes, and hypertension and/or hypercholesterolaemia treatment. There were 7,855 incident admissions for CVD and 2,304 deaths during follow-up (mean time from recruitment, 2.2 y for CVD admission and 2.8 y for mortality. Risks of CVD and death increased steadily with severity of erectile dysfunction. Among men without previous CVD, those with severe versus no erectile dysfunction had significantly increased risks of ischaemic heart disease (adjusted relative risk [RR] = 1.60, 95% CI 1.31-1.95, heart failure (8.00, 2.64-24.2, peripheral vascular disease (1.92, 1.12-3.29, "other" CVD (1.26, 1.05-1.51, all CVD combined (1.35, 1.19-1.53, and all-cause mortality (1.93, 1.52-2.44.

    Full Text Available Erectile dysfunction adversely affects up to 20% of all men and is the most commonly treated sexual disorder. The public health implications of this condition are significant and represent a challenge for our healthcare system. The physiological pathways responsible for erections have been extensively studied, and much advancement has been made since the introduction of phosphodiesterase 5 inhibitors. Newer agents, such as dopaminergic and melanocortin receptor agonists, which target central erectogenic pathways, are under investigation. Newer formulations and delivery methods of existing medications such as alprostadil will also be introduced in the near future. Furthermore, low-intensity shockwave lithotripsy and stem cell regenerative techniques are innovative approaches to the treatment of erectile dysfunction.

    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.

    The aim of this study was to examine the connective tissue of penis in normal individuals and in patients with erectile dysfunction (ED) and Peyronie's disease (PD) using computer methods of image analysis. Penis tissues were obtained from 20 males aged 20-40 years who died in accidents, penis biopsies were taken from 23 patients with ED and 9 patients with PD (average age: 51 +/- 11.5 years). In both groups of patients, the volumetric fraction of collagen fibers in the tunica albuginea and corpora cavernosa was increased, while that one of elastic fibers was decreased. At the same time, the changes of elastic fibers were noted: the fibers become thinner and formed "rods". The reduction of the amplitude and the wavelength in the collagen fibers of the tunica albuginea in patients with ED and the presence of fibrous plaques in corpora cavernosa in in patients with PD were registered. The methods of computer image analysis may improve the morphologic diagnosis of ED and PD.

    Few studies have investigated the relationship between chronic rhinosinusitis (CRS) and erectile dysfunction (ED). This case-control study aimed to investigate the association between CRS and the risk of ED in a large national sample. Tapping Taiwan's National Health Insurance Research Database, we identified people 30 years or older with a new primary diagnosis of CRS between 1996 and 2007. The cases were compared with sex- and age-matched controls. We identified 14 039 cases and recruited 140 387 matched controls. Both groups were followed up in the same database until the end of 2007 for instances of ED. Of those with CRS, 294 (2.1%) developed ED during a mean (SD) follow-up of 3.20 (2.33) years, while 1 661 (1.2%) of the matched controls developed ED, mean follow up 2.97 (2.39) years. Cox regression analyses were performed adjusting for sex, age, insurance premium, residence, hypertension, hyperlipidemia, diabetes, obesity, coronary heart disease, chronic kidney disease, chronic obstructive pulmonary disease, asthma, allergic rhinitis, arrhythmia, ischemic stroke, intracerebral hemorrhage, and medications. CRS was revealed to be an independent predictor of ED in the fully adjusted model (HR = 1.51; 95% CI = 1.33-1.73; P < 0.0001). PMID:27578370

    We interviewed a population sample of 2412 men aged 40-70 y in Brazil, Italy, Japan and Malaysia about medical history, lifestyle habits and sexual behavior. Men were classified as having moderate or complete erectile dysfunction (ED) if they reported to be sometimes or never able to achieve and maintain an erection satisfactory for sexual intercourse, respectively. There were 1335 men with no diagnosis of cardiovascular or prostate diseases, diabetes, ulcer or depression, nor taking hormones. The prevalence of ED was 16.1%. ED was associated with age (the risk increased 8% per y), moderate (odds ratio (OR)=2.2) or severe (OR=4.9) lower urinary tract symptoms and smoking (OR=2.3 for >30 cigarettes/day). It was inversely associated with physical activity (OR=0.5) and higher educational levels. Between the ages of 40 and 70 y, almost one in six 'healthy' men is affected by ED. Further research should look at preclinical disease stages and genetic factors. PMID:12934052

    Our objectives were to determine the prevalence of erectile dysfunction (ED) in Brazil and to explore potential sociodemographic, medical, and lifestyle correlates. A cross-sectional, population-based, household survey was conducted in Salvador, Bahia, Brazil. Cluster samples of representative households were randomly selected for interviews. Of 654 eligible subjects, 602 (92%) participated. A structured questionnaire was administered by trained interviewers. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. All data were obtained by self-report. The age-adjusted prevalence of ED was 39.5% (minimal 25.1%, moderate 13.1%, severe 1.3%). Prevalence and severity increased with age. Having never been married, diabetes, depression, or prostate disease and current depressive or lower urinary tract symptoms were significantly (P<0.05) associated with increased prevalence. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology. PMID:12161762

    2001-01-01

    Erectile dysfunction (ED) is a highly prevalent disorder affecting an estimated 152 million men worldwide and is associated with a variety of behavioral risk factors, such as cigarette smoking and excessive alcohol consumption, as well as numerous age-related medical conditions, notably type-2 diabetes mellitus and cardiovascular disease. A rational step-wise approach which includes comprehensive medical and sexual history, a focused physical examination and essential laboratory tests such as fasting glucose, lipid profile and testosterone assay is to be preferred. Current diagnostic work-up does not recommend any of the specialized tests which were previously considered mandatory-i. e. penile pharmacotesting, Duplex ultrasound and nocturnal penile tumescence. Hormonal replacement therapy is appropriate only in the hypogonadal male with ED. Prior to direct intervention, the physician should consider altering modifiable risk factors or causes, although frequently insufficient to reverse ED completely. When indicated, oral therapy with new molecules (phosphodiesterase inhibitors or apomorphine) is the first-line treatment for the majority of patients because of potential benefits and lack of invasiveness.

    2016-01-01

    Aim The aim of this review was to summarize the ocular action of the most common phosphodiesterase (PDE) inhibitors used for the treatment of erectile dysfunction and the subsequent visual disorders. Method This is a literature review of several important articles focusing on the pathophysiology of visual disorders induced by PDE inhibitors. Results PDE inhibitors have been associated with ocular side effects, including changes in color vision and light perception, blurred vision, transient alterations in electroretinogram (ERG), conjunctival hyperemia, ocular pain, and photophobia. Sildenafil and tadalafil may induce reversible increase in intraocular pressure and be involved in the development of non-arteritic ischemic optic neuropathy. Reversible idiopathic serous macular detachment, central serous chorioretinopathy, and ERG disturbances have been related to the significant impact of sildenafil and tadalafil on retinal perfusion. Discussion So far, PDE inhibitors do not seem to cause permanent toxic effects on chorioretinal tissue and photoreceptors. However, physicians should write down any visual symptom observed during PDE treatment and refer the patients to ophthalmologists. PMID:27799745

    It is of great importance to investigate an effective and reliable medication against chronic renal failure (CRF)-related erectile dysfunction (ED), which aims to improve patients' life qualities. The concentrations of cyclic guanosine monophosphate (cGMP) in the corpus cavernosal smooth muscle of both CRF and control rabbits were measured. The effects of various concentrations of tadalafil, papaverine, and sodium nitroprusside on the relaxation responses of corpus cavernosal smooth muscle pre-contracted with phenylephrine in CRF rabbits were observed. There was significant difference in the concentration of cGMP between CRF and control rabbits (P<0.01). Tadalafil had the greatest impacts on CRF rabbits when given the same concentration of papaverine or sodium nitroprusside and particularly significant differences were identified under the concentration levels of 10-5 and 10-4 mol/L (P<0.01). The results suggest that the cGMP concentrations of the corpus cavernosum had been greatly reduced in CRF rabbits compared with control rabbits and that tadalafil may be an ideal medication for use in the treatment of CRF-related ED.

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

    2005-10-01

    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.

    Microdesmis keayana (Pandaceae) is an African tropical plant whose roots are used in traditional medicine for erection impairment but the compounds responsible for its action are unknown. Two major alkaloids recently isolated from the roots of M. keayana, keayanidine B and keayanine, were tested for vasorelaxing properties using isolated rat aortic rings precontracted by phenylephrine to confirm its traditional use. Influence of the alkaloids on the endothelial production of endothelial nitric oxide synthase (eNOS) was measured by quantitative polymerase chain reaction (QPCR) analysis. Scavenging activities were assessed versus 1,1-diphenyl-2-picrylhydrazyle (DPPH) and reactive oxygen species (ROS) such as superoxide anion (O(2)(*-) and hydrogen peroxide (H(2)O(2)) in cell-free and cellular systems. The results showed that keayanidine B and keayanine had significant vasorelaxing properties. This effect could be due to their strong antioxidant activity versus O(2)(*-) and H(2)O(2) and to their stimulation of eNOS mRNA expression. Therefore these alkaloids could indirectly stimulate NO production in the vascular bed and would explain the traditional use of M. keayana in erectile dysfunction. PMID:19107738

  5. Brain networks during free viewing of complex erotic movie: new insights on psychogenic erectile dysfunction.

    Nicoletta Cera

    Full Text Available 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.

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.

    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.

    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.)

    Despite the well-documented relationship of socioeconomic factors (SEF) to various health problems, the relationship of SEF to erectile dysfunction (ED) is not well understood. As such, the goals of this paper are: (1) to determine whether incident ED is more likely to occur among men with low SEF; and (2) to determine whether incident ED varies by SEF after taking into consideration other well-established ED risk factors that are also associated with SEF such as smoking, diabetes, and high blood pressure. We used data from 797 participants in the longitudinal population-based Massachusetts Male Aging Study (baseline 1987-1989, follow-up 1995-1997) who were free of ED at baseline and had complete data on ED and all risk factors. ED was determined by a self-administered questionnaire and its relationship to SEF was assessed using logistic regression. We first analyzed the age-adjusted relationship of education, income, and occupation to incidence of ED. The results show that men with low education (O.R. = 1.46, 95% C.I. = 1.02-2.08) or men in blue-collar occupations (O.R. = 1.68, 95% C.I. = 1.16-2.43) are significantly more likely to develop ED. For the multivariate model, due to multicollinearity among education, income, and occupation, we ran three separate models. After taking into consideration all the other risk factors--age, lifestyle and medical conditions--the effect of occupation remained significant. Men who worked in blue-collar occupations were one and a half times more likely to develop ED compared to men in white-collar occupations (O.R. = 1.55, 95% C.I. = 1.06-2.28).

    Full Text Available Samuel L Washington III1, Alan W Shindel21School of Medicine, University of California at San Francisco, San Francisco, California, USA; 2Department of Urology, University of California at San Francisco, San Francisco, California, USAAbstract: Selective phosphodiesterase type 5 inhibitors (PDE5Is have revolutionized the ­treatment of erectile dysfunction (ED in men. As an on-demand treatment, PDE5Is have excellent efficacy and safety in the treatment of ED due to a broad spectrum of etiologies. Nevertheless, these drugs do have side-effect profiles that are troublesome to some patients, eg, headache, dyspepsia, myalgia, etc. Furthermore, many patients and their partners dislike the necessity of on-demand treatment for ED, citing a desire for greater spontaneity with sexual interactions. In 2008, approximately 10 years after the release of the first commercially available PDE5I, a paradigm shift in the management of ED occurred with the approval of once-daily dose of tadalafil by the US Food and Drug Administration for the management of ED. The prolonged half-life of tadalafil lends itself well to this dosing regimen and conveys the advantage of separating medication from sexual interactions; lower dose therapy also carries the theoretical benefit of lower incidence of side effects. In this study, we review the current state of the art with respect to this new management strategy for ED, highlighting published reports of the efficacy and tolerability of the daily dose tadalafil regimen.Keywords: PDE5 inhibitor, on-demand therapy, side effects, daily dosing

    Aim: To evaluate the plasma TGF-β1 level in erectile dysfunction (ED) patients of various causes. Methods:Sixty-two patients with ED and 26 potent men were subjected to the study. Based on multidisciplinary work-ups,including medical history, physical examinations, blood tests with lipid profile and hormones, penile duplex Doppler ultrasonogram and neurophysiological tests, causes for ED were classified as psychogenic (n= 15), neurogenic (n=16)and vasculogenic (n=31). The plasma TGF-β1 level was measured by the ELISA method. Results: The plasma TGF-β1 level was significantly increased in the ED group (6.7±4.9 ng/mL), compared to the control (4.0±2.1 ng/mL) (P<0.01). In the ED groups, there was a significant increase in the vasculogenic group (9.0±5.5 ng/mL), compared to the psychogenic (3.8±1.8 ng/mL) and neurogenic groups (4.8±3.2 ng/mL) (P<0.01). Of the vascular risk factors,both the smoking (7.5±4.7 ng/mL) and dyslipidemia groups (7.4±4.4 ng/mL) showed significantly increased plasma TGF-β1 levels, compared to the non-smokers (5.5±2.8 ng/mL), and those without dyslipidemia (4.8±2.8ng/mL) (P<0.05). Conclusion: Vascular risk factors are associated with an elevated plasma TGF-β1 level, which may contribute to cavernous fibrosis and ED. (Asian J Androl 2004 Dec; 6: 349-353)

    Full Text Available BACKGROUND: Several studies have shown that erectile dysfunction (ED influences the risk of cardiovascular events (CV events. However, a meta-analysis of the overall risk of CV events associated with ED in patients with diabetes has not been performed. METHODOLOGY/PRINCIPAL FINDINGS: We searched MEDLINE and the Cochrane Library for pertinent articles (including references published between 1951 and April 22, 2012. English language reports of original observational cohort studies and cross-sectional studies were included. Pooled effect estimates were obtained by random effects meta-analysis. A total of 3,791 CV events were reported in 3 cohort studies and 9 cross-sectional studies (covering 22,586 subjects. Across the cohort studies, the overall odds ratio (OR of diabetic men with ED versus those without ED was 1.74 (95% confidence interval [CI]: 1.34-2.27; P0.05. Moreover, meta-regression analysis found no relationship between the method used to assess ED (questionnaire or interview, mean age, mean hemoglobin A(1c, mean body mass index, or mean duration of diabetes and the risk of CV events or CHD. In the cross-sectional studies, the OR of diabetic men with ED versus those without ED was 3.39 (95% CI: 2.58-4.44; P<0.001 for CV events (N = 9, 3.43 (95% CI: 2.46-4.77; P<0.001 for CHD (N = 7, and 2.63 (95% CI: 1.41-4.91; P = 0.002 for peripheral vascular disease (N = 5. CONCLUSION/SIGNIFICANCE: ED was associated with an increased risk of CV events in diabetic patients. Prevention and early detection of cardiovascular disease are important in the management of diabetes, especially in view of the rapid increase in its prevalence.

    Aim: To assess the behavior of patients with diabetes mellitus (DM) and erectile dysfunction (ED) during 10 consecutive years of treatment with self-injection of vasoactive drugs. Methods: Thirty-eight diabetic men, including 12with type Ⅰ and 26 with type Ⅱ diabetes, were followed up regularly for 10 years after they began self-injecting for severe ED. Real time rigidity assessment was used for the objective determination of the initial dosage and then doses were regulated in order to introduce an erection suitable for penetration and maintenance of erection for approximately 30 min. Patients were followed up every two months, and doses were increased only when the treatment response was not satisfactory. Results: The number of injections used per year by the patients was reduced each year (mean numbers: 50 in the first year and 22.5 in the 10th) and treatment shifted towards stronger therapeutic modalities (mixtures of vasoactive drugs instead of prostaglandin El alone). Type Ⅰ diabetic men were standardized to a level of treatment as early as 5 years after the initiation of treatment. That level was finally reached by type Ⅱ patients after another 4-5 years. Conclusion: Treatment with self-injections of vasoactive drugs in diabetic men with severe ED is a safe and effective alternative in the long term. Diabetic men of both types show the same preferences in quality and quantity of treatment after 10 years. The key point for maintenance in treatment is the adjustment of the therapeutic method and dosage to optimal levels for satisfactory erections.

    Full Text Available Caffeine is consumed by more than 85% of adults and little is known about its role on erectile dysfunction (ED in population-based studies. We investigated the association of caffeine intake and caffeinated beverages with ED, and whether these associations vary among comorbidities for ED.Data were analyzed for 3724 men (≥20 years old who participated in the National Health and Nutrition Examination Survey (NHANES. ED was assessed by a single question during a self-paced, computer-assisted self-interview. We analyzed 24-h dietary recall data to estimate caffeine intake (mg/day. Multivariable logistic regression analyses using appropriate sampling weights were conducted.We found that men in the 3rd (85-170 mg/day and 4th (171-303 mg/day quintiles of caffeine intake were less likely to report ED compared to men in the lowest 1st quintile (0-7 mg/day [OR: 0.58; 95% CI, 0.37-0.89; and OR: 0.61; 95% CI, 0.38-0.97, respectively], but no evidence for a trend. Similarly, among overweight/obese and hypertensive men, there was an inverse association between higher quintiles of caffeine intake and ED compared to men in the lowest 1st quintile, P≤0.05 for each quintile. However, only among men without diabetes we found a similar inverse association (Ptrend = 0.01.Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day. This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies.

    2006-01-01

    Aim: Nitric oxide (NO)-mediated smooth muscle relaxation causes penile erections. The endothelial NO synthase (eNOS) coenzyme tetrahydrobiopterin (BH4) converts eNOS-mediated catalytic activity from oxygen radical to NO production, improving endothelial function and vascular smooth muscle relaxation. Methods: Using quantitative immunohistochemistry, 8-isoprostane and nitrotyrosine concentrations were compared in cavernosal tissue from 17potent and 7 impotent men, and the effect of single oral doses of BH4 on penile rigidity and tumescence was investigated.The pharmacodynamic effect of single oral doses of BH4 on penile rigidity and tumescence was investigated in a randomized, placebo-controlled, double-blind cross-over fashion in 18 patients with erectile dysfunction (ED) while receiving visual sexual stimulation. Results: 8-isoprostane content in endothelium and smooth muscle was significantly higher in impotent patient samples; the level of nitrotyrosine was unchanged in ED patients. Relative to placebo,a single dose of 200 mg BH4 led to a mean increase in duration of > 60% penile rigidity (33.5 min [95% confidence interval (CI): 13.1-49.3] at base and 29.4 min [95% CI: 8.9-42.2] at tip). A 500-mg dose increased the relative duration of>60% penile rigidity by 36.1 min (95% CI: 16.3-51.8) at the base and 33.7 min (95% CI: 11.4-43.9) at the tip. Treatments were well tolerated. Conclusion: BH4 treatment is suggested to switch eNOS catalytic activity from super-oxide to NO formation, leading to a reduced formation of free radical reaction product 8-isoprostane without alteration of nitrotyrosine. The observed results make BH4 a suitable candidate as an ED treatment through reconstitution of altered catalytic activity of the eNOS.

    Full Text Available Usama A Fahmy Department of Pharmaceutics & Industrial Pharmacy, Faculty of Pharmacy, King Abdulaziz University, Jeddah, Saudi Arabia Abstract: Vesicular drug delivery systems have recently gained attention as a way of improving dosing accuracy for drugs with poor transdermal permeation. The current study focuses on utilization of the natural biocompatible vesicles to formulate vardenafil nanoethosomes (VRD-NE, for the enhancement of their transdermal permeation and bioavailability. Fifteen formulations were prepared by thin-layer evaporation technique according to Box–Behnken design to optimize formulation variables. The effects of lipid composition, sonication time, and ethanol concentration on particle size and encapsulation efficiency were studied. The diffusion of vardenafil (VRD from the prepared nanoethosomes specified by the design was carried out using automated Franz diffusion cell apparatus. The optimized formula was investigated for in vivo pharmacokinetic parameters compared with oral VRD suspension. Confocal laser scanning microscopy images were used to confirm enhanced diffusion release of VRD in rat skin. The results showed that the optimized formula produced nanoethosomes with an average size of 128 nm and an entrapment efficiency of 76.23%. VRD-NE provided a significant improvement in permeation with an enhancement ratio of 3.05-fold for a film made with optimally formulated VRD-NE compared with a film made with VRD powder. The transdermal bioavailability of VRD from the nanoethosome film was approximately twofold higher than the oral bioavailability from an aqueous suspension. VRD-NE thus provide a promising transdermal drug delivery system. As a result, management of impotence for a longer duration could be achieved with a reduced dosage rate that improves patient tolerability and compliance for the treatment of erectile dysfunction.Keywords: Box–Behnken design, impotence, vesicles, nanoparticles

    Avanaifl, a potent new selective phosphodiesterase type 5 (PDE5) inhibitor, has been developed for the treatment of erectile dysfunction (ED). We carried out a systematic review and meta-analysis to assess the efifcacy and safety of this drug for the treatment of ED. A literature review was performed to identify all published randomized, double-blind, placebo-controlled trials of avanaifl for the treatment of ED. The search included the following databases:MEDLINE, EMBASE and the Cochrane Controlled Trials Register. The reference lists of the retrieved studies were also investigated. Four publications, involving a total of 1381 patients, were used in the analysis, including four randomized controlled trials (RCTs) that compared avanaifl with a placebo. Among the co-primary efifcacy end points indicating that avanaifl 100 mg was more effective than a placebo were successful vaginal penetration (SEP2) (the odds ratio (OR)=5.06, 95%conifdence interval (CI)=3.29-7.78, P<0.00001) and successful intercourse (SEP3) (OR=3.99, 95%CI=2.80-5.67, P<0.00001). Men randomized to receive avanaifl were less likely than those receiving the placebo to drop out due to an adverse event (AE) (OR = 1.48, 95% CI = 0.54-4.08, P= 0.44). Speciifc AEs with avanaifl included headache and lfushing, which were signiifcantly less likely to occur with placebo. This meta-analysis indicates that avanaifl 100 or 200 mg is an effective and well-tolerated treatment for ED. Compared with avanaifl 100 mg, patients who take avanaifl 200 mg are more likely to experience headaches.

    Full Text Available Background: Erectile dysfunction is an important problem in men and an organic cause is found in about 50% of cases. When a vasculogenic etiology is suspected, imaging assessments are of great help. Cavernosography is traditionally recognized as an imaging modality for evaluation of venous leakage in men with impotency. We employed CT cavernosography as a novel technique for demonstrating penile venous anatomy and leaking veins.Methods: In the present case series study, we recruited 45 patients with erectile dysfunction by convenient sampling at Hazrat Rasoul Akram Hospital in Tehran, Iran, during one year (1390. The patients had previously been diagnosed with venous incompetency by Doppler study. After intracavernosal injection of prostaglandin E1, we injected sterile normal saline into the corpora cavernosa to achieve penile erection. Later, we injected contrast media into the corpus cavernosum, which was followed by CT scan of the penis and pelvic area to show the venous anatomy and leakage sites.Results: The mean age of the patients was 35.8±8.9 years. 36 (80% patients had venous leakage in crural veins, 27 (60% in cavernosal veins, 27 (60% in circumflex veins, 24 (52.3% in urethral veins, 21 (46.7% in deep dorsal vein, 3 (6.7% in para-arterial veins and 3 (6.7% in corpus spongiosum. Conclusion: The results of this study show the high prevalence of venous leakage in patients referring for erectile dysfunction. Moreover, CT cavernosography was shown to be a useful method for evaluating penile venous system and its related leakage sites which are important for surgical planning.

    Emperor Shen-Nung was the second of China's mythical emperors (3500-2600 BCE). Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal plants which he personally tasted. Through his treatise 'Shen Nung Benchau Jing', we relive Emperor Shen-Nung's contribution to urology with reference to his management of erectile dysfunction. Time-related sources in medical and historical literature were reviewed, including the 'Shen Nung Benchau Jing' (The medicine book of Emperor Shen-Nung), archives and manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine, London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History, Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago. Agricultural clan leader, Emperor Shen-Nung, was said to have a 'crystal-like belly' to watch the reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung's contributions to herbal medicine. He experienced a warm and sexually pleasurable feeling after chewing the root. He advocated this as a treatment for erectile dysfunction and used it to stimulate sexual appetite. The reputation of ginseng as an aphrodisiac is based on the doctrine of signatures, since the adult root has a phallic shape. Shen-Nung believed that ginseng's resemblance to the human form is proof of its rejuvenative and aphrodisiac properties. It was believed that the closer the similarity to the human figure, the more potent the root. The use of ginseng for erectile dysfunction by Emperor Shen-Nung was unique for its time. It continues to hold parallels as a modern-day herbal aphrodisiac 5000 years on.

    2013-10-01

    Full Text Available Background: Arterial insufficiency is a well-recognized etiology of erectile dysfunction. Moreover, nowadays it is appreciated that it can herald silent coronary artery disease in involved patients. However color Doppler study of penis with intracavernosal injection (ICI of Papaverin, as a helpful diagnostic study, is somehow time consuming and technically demanding, as a result, radiologists are reluctant to accomplish. Hence, in a search for more plausible parameters, we were determined to validate PSV in flaccid state for predicting possible arterial insufficiency in patients. Methods: In a cross sectional study to evaluate diagnostic tests, accomplished in Hasheminejad Urology center in Tehran throughout 2011, we studied 59 patients with the complaint of erectile dysfunction. They were referred to our ultrasound clinics by urologists in order to undergo color Doppler study of penis by ICI of Papaverin. They were studied comprehensively before and after injection. Primary and secondary diagnostic criteria of arterial disease in color Doppler and consequently the physiologic event of full erection were designated as gold standard diagnostic considerations. The resulted data were matched and analyzed with SPSS software. Results: Fifty nine patients underwent the study, with the mean age of 45.6 ± 13.1 (24 to 74 year old. Twenty two cases revealed normal study (non-organic causes as 37.3%, 29 were classified as venous leakage, and eight of them demonstrate arterial insufficiency in the study. A flaccid state PSV of 10.5 cm/s as cut off had a sensitivity of 93.8%, specifity of 91.3% and negative predictive value of 93.8% to predict arterial disease. Conclusion: A flaccid state PSV of 10.5 has a suitable statistical value to proclaim arterial insufficiency in cavernosal arteries in patients with erectile dysfunction as a complaint.

    Aim: To investigate whether the autonomic nervous system (ANS) components are suitable biological markers for representing well-being in patients with erectile dysfunction (ED). Methods: The present study included 74 male patients who had applied for check-ups in the cardiology outpatient clinic at Kirikkale University (Kirikkale, Turkey) and who had been diagnosed as having hyperlipidemia. Of these patients, 26 had an additional diagnosis of ED and made up the patient group. The remaining 48 patients formed the control group. Well-being was assessed with short- form 36 (SF-36). The International Index of Erectile Function (IIEF) was used as a measure of libido and erectile function. Quantitative assessment of the ANS was made based on the analysis of heart rate variability by means of 24-h holter monitorization. Results: Comparisons between the ED and control groups showed significant differences only in energy scale of SF-36. The ED group also had significantly higher values of sympathetic activity. Except for the general health score of SF-36, which was found to be correlated with parasympathetic activity only in ED group, there were similar correlation patterns within the groups. Although well-being and sympathetic activity were corre- lated negatively, parasympathetic activity and well-being were correlated positively. Conclusion: Quantitative as- sessment of the ANS by heart rate variability analysis might be a suitable marker for well-being of patients with ED. (Asian J Androl 2008 Jul; 10: 643-650)

    Like most jurisdictions, Canada prohibits direct-to-consumer advertising (DTCA) of prescribed drugs. However, direct-to-consumer information (DTCI) is permitted, allowing companies to inform the public about medical conditions. An analysis of Eli Lilly's 40over40 promotion campaign for erectile dysfunction (ED), which included a quiz on ED, shows that DTCI, like DTCA, can be an effective means of drug familiarization. The pharmaceutical industry is "playing by the rules" currently in effect in Canada. Regulators should thus seriously consider whether existing rules permitting DTCI actually meet stated objectives of protecting the public from marketing campaigns (i.e., DTCA) that may deliver misleading information.

    Background Renal transplants can improve the quality of life for recipients, but the quality of their sexual life might not be improved. This study was conducted to research the prevalence of erectile dysfunction (ED) and the influential factors in male renal transplant recipients (RTRs).Methods A cross-sectional survey was conducted in three renal transplantation centers. Structured questionnaires were administrated by trained interviewers to 824 male renal transplant patients, who had active sexual lives in the last 6 months.Results Complaints of ED were reported by 75.5% of the 809 RTRs (age range 19-75 years, mean age (45±10) years),whose questionnaires were completed. Mild, moderate and severe ED were reported at 53.6%, 8.3% and 13.6%,respectively. The mean age and the graft duration were significantly higher in male RTRs with ED compared to potent graft recipients (P=-0.00 and 0.04, respectively). The prevalence of ED increased with the increase in age. It was 60.7%, 65.8%,75.2%, 87.5% and 92.2% in patients with age below 30 years, 31-40 years, 41-50 years, 51-60 years and over 60 years,respectively (P=0.000). Moreover, the severity of ED increased with aging. The percentage of moderate and severe cases of ED increased from 6.7% in patients below 40 years to 28.9% in those over 40 years (P=0.000). The prevalence of ED in the RTR who had no occupation was higher than in those who were holding a position (P=0.001). The prevalence of ED decreased with the increase in the education level. The prevalence of ED was 94.3%, 86.4%, 74.0% and 67.8% in men with elementary school or lower, middle school, high school, and college or higher degrees, respectively (P=0.000). Patients,whose distal end of arteria iliaca interna was interrupted and underwent iterative transplantation, worried transplanted kidney function was impacted by sexual life, and received cyclosporine (CsA)-based immunosuppressive regimens, were more likely to have ED (P=0.000, 0.001, 0.000, 0

    The aim was to evaluate the effectiveness of a progressive program, starting with simple methods and, when not effective, moving to more complex methods, to treat erectile dysfunction (ED) in patients with diabetes mellitus. A total of 284 diabetic patients with ED entered into a 6-phase program starting with sildenafil citrate (Viagra). Those with contraindications, side effects, or negative response (erection insufficient for vaginal penetration) were switched to the vacuum erection device (VED), and then progressively (for failures) to intracavernous injection (ICI), sildenafil citrate+ICI, ICI+VED, and penile prosthesis. Patients were followed for 2 y. Of the 284 patients 276 patients were eligible for sildenafil citrate and 147 (53.3%) responded positively, but 25 (9.1%) patients stopped it soon due to adverse effects. Of 162 patients (129 nonresponders, eight noneligible for the sildenafil and 25 patients who dropped out due to adverse effects), treated with VED, 114 (70.4%) responded well, however, only 19 (11.7%) patients agreed to continue its use. Of the remaining 143 patients (nonresponders, noneligible for the previously mentioned treatments and patients who dropped out due to adverse effects), 103/143 (72%) responded to ICI, 27/40 (67.5%) to sildenafil+ICI, and 9/13 (69.2%) to ICI+VED. Four patients received a penile implant. At the 2 y follow-up, 81 of 284 patients who entered the study (28.5%) were still responding to sildenafil, seven (2.5%) to VED, 113 (39.8%) to ICI, 24 (8.5%) to sildenafil+ICI, two (0.7%) to ICI+VED; 15 (5.3%) had a penile implant. In all 17 (6%) patients reported spontaneous erections, 11 (3.9%) stopped the treatment due to family reasons and 14 (4.9%) failed the treatment. In conclusion, the progressive treatment program for ED seems to be very effective for diabetic patients, yielded a complete response for short-term and 91.2% rate of success at the end of 2 y follow-up.

    Background Targeted therapy for erectile dysfunction (ED) involves fewer screening tests and provides a variety of treatment choices for patients.Although the advantage of targeted therapy in diagnosis and therapy for ED has been recognized,the rational mode for oriented ED therapy has not been established.This study aimed to investigate targeted diagnosis and therapy for ED.Methods A total of 198 patients with ED were included in the study.After intracavernosal vasoactive agent injection was given,color Doppler flow imaging was performed and penile rigidity was classified as Schramek grade 5 (10 minutes duration),grade 4 (10 minutes duration),grade 3 and grade 2,defining four patient groups as group Ⅴ (143 cases),group Ⅳ (23 cases),group Ⅲ (18 cases),and group Ⅱ (14 cases).Appropriate and acceptable treatment was recommended to patients according to erection grade.Results In 198 patients with ED,the peak systolic velocity,end diastolic velocity,and resistance index in the cavemosal artery and dorsal artery and the flow velocity in the deep dorsal vein were not significantly different before injection (P >0.05).After injection,peak systolic velocity,end diastolic velocity,and resistance index in the cavernosal artery were different among the four groups (P<0.05).Between each two groups,the difference in resistance index was significant (P <0.05).The statistical differences in other indexes were not significant (P >0.05).Selective targeted therapy based on erection grade by color Doppler flow imaging improved the clinical satisfaction rate to 91.91% (182/198).Conclusions Based on the routine diagnosis of ED,blood flow indexes in the cavernosal artery are measured by color Doppler flow imaging following minimally invasive intercavernosal injection,which is combined with the Schramek grade of erection.The most appropriate and acceptable treatment is recommended according to the different groups,which improves the clinical satisfaction of treatment for

    Full Text Available Hypercholesterolemia is one of the most important risk factors for erectile dysfunction, mostly due to the impairment of oxidative stress and endothelial function in the penis. The cannabinoid system might regulate peripheral mechanisms of sexual function; however, its role is still poorly understood. We investigated the effects of CB2 activation on oxidative stress and fibrosis within the corpus cavernosum of hypercholesterolemic mice. Apolipoprotein-E-knockout mice were fed with a western-type diet for 11 weeks and treated with JWH-133 (selective CB2 agonist or vehicle during the last 3 weeks. CB2 receptor expression, total collagen content, and reactive oxygen species (ROS production within the penis were assessed. In vitro corpus cavernosum strips preparation was performed to evaluate the nitric oxide (NO bioavailability. CB2 protein expression was shown in cavernosal endothelial and smooth muscle cells of wild type and hypercholesterolemic mice. Treatment with JWH-133 reduced ROS production and NADPH-oxidase expression in hypercholesterolemic mice penis. Furthermore, JWH-133 increased endothelial NO synthase expression in the corpus cavernosum and augmented NO bioavailability. The decrease in oxidative stress levels was accompanied with a reduction in corpus cavernosum collagen content. In summary, CB2 activation decreased histological features, which were associated with erectile dysfunction in hypercholesterolemic mice.

    In this study, the effect of change in chromatographic process variables on the retention behavior of four drugs employed in erectile dysfunction therapy on a calixarene stationary phase is described. Three of these drugs are known to treat erectile dysfunction, namely, sildenafil citrate, tadalafil, and apomorphine hydrochloride, and one drug that is used as opioid analgesic, tramadol hydrochloride, which is quiet widely misused to treat premature ejaculation. The results indicate the importance of considering the structure and pKa values of drugs to be separated along with mobile phase composition. A new optimized, rapid, and accurate liquid chromatography method is also established for simultaneous determination of sildenafil citrate, tadalafil, and apomorphine hydrochloride in pharmaceutical preparations and bulk powders. The chromatographic separation of the three pharmaceuticals was achieved on a calixarene column in less than 10 min using a binary mobile phase of 35% acetonitrile and 65% 50 mM sodium perchlorate pH2.5 at 1 mL/min flow rate. The method was validated for system efficiency, linearity, accuracy, precision, limits of detection and quantitation, specificity, stability, and robustness. Statistical analysis proved that the method enabled reproducible and selective quantification of all three analytes in bulk drugs and in pharmaceutical preparations.

    We evaluated penile prosthesis implantation with tunica albuginea-relaxing incisions without grafting in the treatment of Peyronie's disease associated with erectile dysfunction.Between April 2005 and June 2011,62 patients underwent surgery due to severe Peyronie's disease associated with erectile dysfunction.Malleable and inflatable penile prostheses ware inserted in 49 and 13 cases,respectively.Penile prostheses were inserted into the corpora cavemosa using the standard ventral approach.After lifting the neurevascular bundle,the tunica albuginea was incised and opened at the plaque region to correct the deformities and to lengthen the penis.Subsequently,the wide neurovascular bundle was replaced,and all incisions of the tunica albuginea were covered to prevent corporal grafting.In the median follow-up of 35 months (range 14-82 months),the penis was completely straightened in 59 (95%) patients.Numbness of the glans,which the patients found initially upsetting,decreased or disappeared spontaneously 3-6 months later.Penile prosthesis implantation with tunica albuginea incisions is a viable alternative in the treatment of Peyronie's disease because the extensive dissection of the neurovascular bundle allows a good approach to the plaque and provides excellent covering of the incised tunica albuginea witheut additional grafting.

    Full Text Available Amr Abdel Raheem1, Philip Kell21St. Peter’s Andrology Department, The Institute of Urology, London, and Cairo University, Egypt; 2St. Peter’s Andrology Department, The Institute of Urology, London, UKAbstract: Erectile dysfunction (ED is a problem that may affect up to 52% of men between the ages of 40 and 70. It can be distressing because of its negative effect on self-esteem, quality of life, and interpersonal relationships. Oral phosphodiesterase-5 inhibitors (PDE5 inhibitors are now the first choice of treatment in ED. The availability of three (sildenafil citrate, tadalafil, and vardenafil well tolerated and effective oral PDE5 inhibitors gives treatment options for men with ED. Although the mechanism of action is the same for the three drugs, they differ in their pharmacokinetics. Several preference studies were conducted between the three PDE5 inhibitors but they were not free from bias. Because of the lack of overwhelming reliable data showing that one PDE5 inhibitor is superior to another, current opinion is that the individual patient should have the opportunity to test all three drugs and then select the one that best suits him and his partner.Keywords: erectile dysfunction, PDE5 inhibitors, patient preference

    Opiate antagonists can indirectly stimulate the secretion of luteinizing hormone (LH) and testosterone, as well as sexual functions in animals and humans. We therefore treated 20 otherwise healthy men with idiopathic erectile dysfunction aged 46.3 +/- 2.7 years (mean +/- SE, range 23.9-63.3) in a double-blind study with an opiate antagonist, naltrexone, or placebo. The erectile dysfunction of these men had persisted for 3.6 +/- 0.5 years despite libido maintenance; standard procedures had excluded any organic causes. Trial duration was 12 weeks overall. After a 4-week forerun, the patients received at first 25 mg naltrexone/day orally or placebo for 4 weeks followed by 4 weeks of a 50-mg dose of naltrexone/day or placebo. Each day the patients filled out a questionnaire detailing libido, degree of erection, frequency of sexual intercourse, and spontaneous morning erections. Serum concentrations of gonadotropins and testosterone were determined radioimmunologically in the initial stage and at the end of each phase. Both patient collectives had similar initial factors. The group treated with naltrexone showed a significant rise in spontaneous early morning erections during the treatment: from 2.8 +/- 0.3 to 4.2 +/- 0.3 a week (P testosterone concentrations in both groups. Thus, treatment with naltrexone significantly raises the rate of spontaneous early morning erections when compared to controls.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8294223

    Aim: To identify possible risk factors for erectile dysfunction (ED) after transurethral resection of prostate (TURP)for benign prostatic hyperplasia (BPH). Methods: Between March 1999 and March 2004, 629 patients underwent TURP in our department for the treatment of symptomatic BPH. All patients underwent transrectal ultrasound examination. In addition, the flow rate, urine residue, International Prostate Symptom Score (IPSS) and quality of life (QOL) were recorded for those who presented without a catheter. Finally, the erectile function of the patient was evaluated according to the International Index of Erectile Function Instrument (IIEF-5) questionnaire. It was determined that ED existed where there was a total score of less than 21. The flow rate, IPSS and QOL assessment were performed at 3 and 6 months post-treatment. The IIEF-5 assessment was repeated at a 6-month follow-up. A logistic regression analysis was used to identify potential risk factors for ED. Results: At baseline, 522 (83 %) patients answered the IIEF-5 questionnaire. The mean patient age was (63.7 ± 9.7) years. The ED rate was 65 %. After 6 months, 459 (88 %) out of the 522 patients returned the ⅡEF questionnaire. The rest of the group was excluded from the statistical analysis. Six months after TURP, the rate of patients reporting ED increased to 77 %. Statistical analysis revealed that the only important factors associated with newly reported ED after TURP were diabetes mellitus (P = 0.003, r = 3.67) and observed intraoperative capsular perforation (P = 0.02, r = 1.12). Conclusion: The incidence of postoperative, newly reported ED after TURP was 12 %. Risk factors for its occurrence were diabetes mellitus and intraoperative capsular perforation.

    Introduction Determinants of erectile dysfunction in diabetic men have not been adequately investigated as potential mediators of change. Aim To determine the prevalence and correlates of erectile dysfunction (ED) in overweight men with type 2 diabetes in the multicenter, Look AHEAD trial (Action for Health in Diabetes). Main Outcome Measures International Index of Erectile Function (IIEF), self-reported use of phosphodiesterase type 5 inhibitors, laboratory measures of adiposity, cardiometabolic parameters, and exercise fitness. Methods Male participants aged 45–75 in the Look AHEAD trial in a committed relationship were recruited for an ongoing study of sexual function and diabetes. Eligible participants completed the IIEF questionnaire and provided updated information on use of medical treatments for sexual dysfunction. Baseline sexual function results for participants in the male ancillary study are reported here; intervention data and results for female participants are presented elsewhere. Results A total of 373 eligible male participants completed all sexual function questionnaires, of whom 263 (68.7%) were sexually active at the time of the study. Almost half (49.8%) of the men reported mild or moderate degrees of ED, and 24.8% had complete ED. Among sexually active participants, 42.6% had sought medical help for their problem, and 39.7% reported use of ED medications. ED was significantly associated with age (odds ratio [OR] = 1.05; confidence interval [CI]: 1.01–1.10) baseline HbA1c (OR = 1.31; CI: 1.05–1.63), hypertension history (OR = 2.41; CI: 1.34–4.36), and metabolic syndrome (OR = 3.05, CI: 1.31–7.11). Of note, cardiorespiratory fitness was found to be protective of ED in a multivariable analysis (OR = 0.61; P < 0.001). Conclusions ED is prevalent in this sample of obese, type 2 diabetic men in the Look AHEAD study. Cardiovascular risk factors were highly associated with ED in this population, and cardiorespiratory fitness was protective

    Purpose To investigate the effects of cavernous nerve injury (CNI) on gene expression profiles in the cavernosal tissue of a CNI-induced erectile dysfunction (ED) model and to provide a basis for future investigations to discover potential target genes for ED treatment. Materials and Methods Young adult rats were divided randomly into 2 groups: sham operation and bilateral CN resection. At 12 weeks after CNI we measured erectile responses and performed microarray experiments and gene set enrichment analysis to reveal gene signatures that were enriched in the CNI-induced ED model. Alterations in gene signatures were compared with those in the diabetes-induced ED model. The diabetic-induced ED data is taken from GSE2457. Results The mean ratio of intracavernosal pressure/blood pressure for the CNI group (0.54±0.4 cmH2O) was significantly lower than that in the sham operation group (0.73±0.8 cmH2O, p<0.05). Supervised and unsupervised clustering analysis showed that the diabetes- and CNI-induced ED cavernous tissues had different gene expression profiles from normal cavernous tissues. We identified 46 genes that were upregulated and 77 genes that were downregulated in both the CNI- and diabetes-induced ED models. Conclusions Our genome-wide and computational studies provide the groundwork for understanding complex mechanisms and molecular signature changes in ED. PMID:27437539

    A 34-year-old male patient with familial amyloidotic polyneuropathy (FAP) amyloidogenic transthyretin (ATTR) Valine30Methionine (Val30Met), who underwent a liver transplantation in Sweden in 1994, was treated with sildenafil citrate (Viagra) to ameliorate his erectile dysfunction (ED). Some clinical symptoms and the examination data for autonomic functions were improved after liver transplantation, but ED was never improved after the operation. Five years after liver transplantation, he requested a sildenafil citrate therapy to enhance his erectile potential. One and a half hours after the administration of 25 mg of sildenafil citrate, the skin surface temperature around the pelvic area increased and the penis became erect, though the postdose hemodynamic parameters did not significantly change from the respective baseline or predose values. He was able to have sexual intercourse, though ejaculation did not occur. This case report appears to suggest that sildenafil citrate is an effective drug to treat ED in patients with an organic impairment of the autonomic nervous system without altering systemic circulation.

    The erectile dysfunction is a problem with underlined mediocosocial significance. In this aspect we report our experience in diagnostics and treatment of traumatic vessels - caused erectile dysfunction. Patients are treated by a diagnostic program, which we made on the basis of our experience from the whole group of vessel - caused erectile dysfunction. We have tested and cured 6 patients with traumatic erectile dysfunction. In all the patients we found erectile dysfunction of type `venous leak`, which was diagnosed by digital subtraction cavernosography, which was suggested by the authors. The way of diagnostic research for application of digital subtraction cavernosography is characterized or pelvic angiography independance of the coordinated venous and arterial traumatic laesions such are found in 2 of the patients. The method for surgical treatment is suggested and the long - lasting effect by the treatment is defined by the authors. (orig.)

    To investigate the prevalence, correlates, attitude and treatment seeking behavior of erectile dysfunction(ED) in type2 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 deifned 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 type5 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.

    Objective 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. The aim of this study was to investigate whether taurine, a sulfur-containing amino acid, affects diabetic ED (DED). Methods Type 1 diabetes mellitus was induced in male rats using streptozotocin. After 12 weeks, an apomorphine test was conducted to confirm DED. Only rats with DED were administered taurine or vehicle for four weeks. Age-matched nondiabetic rats were administered saline intraperitoneally for four weeks. Erectile function was evaluated by electrical stimulation of the cavernous nerve. Histologic and molecular alterations of the corpus cavernosum also were analyzed. Results Erectile function was significantly reduced in the diabetic rats compared with in the nondiabetic rats, and was ameliorated 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 restored erectile response as well as histologic and molecular alterations. Conclusions 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.

    A double-blind parallel group comparison design clinical study was conducted in Japanese patients with mild to moderate erectile dysfunction to investigate the efficacy of a supplement containing Pycnogenol® and L-arginine. Subjects were instructed to take a supplement (Pycnogenol® 60 mg/day, L-arginine 690 mg/day and aspartic acid 552 mg/day) or an identical placebo for 8 weeks, and the results were assessed using the five-item erectile domain (IIEF-5) of the International Index of Erectile Function. Additionally, blood biochemistry, urinalysis and salivary testosterone were measured. Eight weeks of supplement intake improved the total score of the IIEF-5. In particular, a marked improvement was observed in 'hardness of erection' and 'satisfaction with sexual intercourse'. A decrease in blood pressure, aspartate transaminase and γ-glutamyl transpeptidase (γ-GTP), and a slight increase in salivary testosterone were observed in the supplement group. No adverse reactions were observed during the study period. In conclusion, Pycnogenol® in combination with L-arginine as a dietary supplement is effective and safe in Japanese patients with mild to moderate erectile dysfunction. PMID:21618639

    Introduction Although previous studies report an association between erectile dysfunction (ED) and smoking, few have examined the impact of passive smoke exposure on ED. This analysis examines the association of active and passive smoking and ED and investigates a dose-response effect of smoking. Methods The Boston Area Community Heath (BACH) survey is a study of urologic symptoms in a racially and ethnically diverse population. BACH used a multistage stratified random sample to recruit 2301 men, aged 30–79 yr, from the city of Boston. ED was assessed using the five-item International Index of Erectile Function. Smoking and passive smoking were assessed by self-report. Analyses adjusted for sociodemographic and lifestyle factors and important chronic illnesses. Results An association between smoking and ED was observed with a significant trend in increased risk of ED with cumulative pack-years of smoking (adjusted odds ratio [OR] = 1.68; 95% confidence interval [CI], 1.03, 2.30 for ≥ 20 pack-years). Compared to never smokers not exposed to passive smoking, men who never smoked but were exposed to passive smoking had a moderate, statistically nonsignificant, increase in risk of ED (adjusted OR = 1.33; 95%CI: 0.69, 2.55) comparable to the OR observed for a cumulative exposure of 10–19 pack-years of active smoking (adjusted OR = 1.25; 95%CI, 0.68, 2.30). Conclusions Results indicate a dose-response association between smoking and ED with a statistically significant effect observed with ≥ 20 pack-years of exposure. Passive smoking is associated with a small, statistically nonsignificant increase in risk of ED comparable to approximately 10–19 pack-years of active smoking. PMID:17383811

    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.

    Peyronie's disease (PD) is a chronic inflammatory disease involving the tunica albuginea of the penis. 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 sexual bother were significantly higher compared with cases with no curvature when the bend angle was ≥30°. Our study confirms that an integrated psychological support with medical treatment is needed in patients with PD. PMID:27486570

  10. Levels of Human Erythrocyte Membrane-Bound and Cytosolic Glycohydrolases Are Associated with Oxidative Stress in Erectile Dysfunction Patients

    2014-01-01

    Full Text Available Oxidative stress (OS and production of NO, by endothelium nitric oxide synthetase (eNOS, are involved in the pathophysiology of erectile dysfunction (ED. Moreover, OS induces modifications of the physicochemical properties of erythrocyte (RBC plasma membranes and of the enzyme content of the same membranes. Due to their role in signalling early membrane alterations in OS-related pathologies, several plasma membrane and cytosolic glycohydrolases of human RBC have been proposed as new markers of cellular OS. In RBC, NOS can be activated and deactivated by phosphorylation/glycosylation. In this regulatory mechanism O-β-N-AcetylGlucosaminidase is a key enzyme. Cellular levels of O-GlcNAcylated proteins are related to OS; consequently dysfunctional eNOS O-GlcNAcylation seems to have a crucial role in ED. To elucidate the possible association between RBC glycohydrolases and OS, plasma hydroperoxides and antioxidant total defenses (Lag-time, cytosolic O-β-N-AcetylGlucosaminidase, cytosolic and membrane Hexosaminidase, membrane β-D-Glucuronidase, and α-D-Glucosidase have been studied in 39 ED patients and 30 controls. In ED subjects hydroperoxides and plasma membrane glycohydrolases activities are significantly increased whereas Lag-time values and cytosolic glycohydrolases activities are significantly decreased. These data confirm the strong OS status in ED patients, the role of the studied glycohydrolases as early OS biomarker and suggest their possible use as specific marker of ED patients, particularly in those undergoing nutritional/pharmacological antioxidant therapy.

    The authors investigated the diagnostic accuracy of dynamic color Doppler sonography (D-CDS) in men with erectile dysfunctions (ED). Terminal microcirculation alterations and their correlation with erectile response after drug testing were investigated with power Doppler energy. Penile sonography in the flaccid state can show calcificic plaques and/or fibrosis of the corpora. Redosing of PGE{sub 1} plus phentolamine during D-CDS is a safe procedure and improves diagnostic accuracy in erectile dysfunctions, with significantly fewer non-responders than redosing of PGE{sub 1} alone. Power Doppler energy shows altered morphology of helicine arterioles otherwise missed at color Doppler and is thus recommended to make an accurate diagnosis in some men with erectile dysfunctions. [Italian] Scopo dello studio e' quello di valutare l'accuratezza diagnostica dell'eco color Doppler dinamico del pene nei soggetti affetti da disfunzione erettile. Inoltre si e' voluto verificale la presenza di alterazioni della vascolarizzazione arteriosa terminale con modulo power Doppler e come la presenza di queste alterazioni del microcircolo si correlino con la risposta erettiva della farmacoinfusione intracavernosa. Con l'eco color Doppler penieno basale e' possibile identificare placche calcifiche e/o fibrosi nei corpi cavernosi. Durante la fase dinamica con color Doppler , la re-iniezione con PGE{sub 1} e fentolamina si e' dimostrata sicura e ha migliorato l'accuratezza diagnostica riducendo il numero di soggetti con mancata risposta erettiva rispetto alla sola PGE{sub 1}. Con power Doppler sono state identificate alterazioni morfologiche delle arterioleelicine non visibili con il color Doppler consentendo la diagnosi piu' precisain alcuni casi di disfunzione erettile.

    Objective The introduction of nerve-sparing radical prostatectomy represents a milestone in the treatment of prostate cancer. However, a certain percentage of cancer survivors still suffer from erectile dysfunction. Recent research has stated that using PDE 5-inhibitors after radical prostatectomy may lead to biochemical recurrence. This study was performed to identify the expression profile of small RNA in rats with neurogenic erectile dysfunction, and to investigate possible genes and signaling pathways involving in the disease. Methods Neurogenic erectile dysfunction (ED) was induced in male rats by bilateral cavernous nerve crushing injury (BCNI). After 28 days, erectile function was evaluated by cavernous nerve electrostimulation. Masson’s trichrome staining was performed to assess histologic changes. RNA was isolated from the corpus cavernosum (CC) of both control rats and neurogenic ED rats. Small RNA sequencing was conducted using an Illumina Hiseq 2,500/2,000 platform. Candidate small RNAs were validated by real-time polymerase chain reaction. Results Intracavernous pressure (ICP) was significantly decreased in BCNI group compared with SHAM group. Corporal tissue in the neurogenic ED rats showed a significantly lower smooth muscle/collagen ratio compared with tissue in the SHAM controls. Real time PCR validated that miR-9a-5p, miR-203a-5p, miR-378a-3p and miR-3557-5p were upregulated, and meanwhile miR-3084a-3p was downregulated. Conclusions Small RNA, including microRNA, may play an important role in the regulation of genes in CC and some certain miRs may participate in post-prostatectomy ED. Further studies will be designed to investigate the specific mechanisms of these changes.

    This study was designed to determine the antioxidant properties and inhibitory effects of extract from Moringa oleifera leaves on angiotensin-I-converting enzyme (ACE) and arginase activities in vitro. The extract was prepared and phenolic (total phenols and flavonoid) contents, radical (nitric oxide (NO), hydroxyl (OH)) scavenging abilities, and Fe2+-chelating ability were assessed. Characterization of the phenolic constituents was done via high performance liquid chromatography-diode array detection (HPLC-DAD) analysis. Furthermore, the effects of the extract on Fe2+-induced MDA production in rats' penile tissue homogenate as well as its action on ACE and arginase activities were also determined. The extract scavenged NO∗, OH∗, chelated Fe2+, and inhibited MDA production in a dose-dependent pattern with IC50 values of 1.36, 0.52, and 0.38 mg/mL and 194.23 µg/mL, respectively. Gallic acid, chlorogenic acid, quercetin, and kaempferol were the most abundant phenolic compounds identified in the leaf extract. The extract also inhibited ACE and arginase activities in a dose-dependent pattern and their IC50 values were 303.03 and 159.59 µg/mL, respectively. The phenolic contents, inhibition of ACE, arginase, and Fe2+-induced MDA production, and radical (OH∗, NO∗) scavenging and Fe2+-chelating abilities could be some of the possible mechanisms by which M. oleifera leaves could be used in the treatment and/or management of erectile dysfunction.

    The prevalence and correlates of erectile dysfunction (ED) in developing countries are largely unknown. Our objectives were to determine the prevalence and associated factors of ED in three countries (Pakistan, Egypt, Nigeria) that represent very different cultures. Men 35-70y of age seeking primary medical care answered a structured questionnaire adapted to reflect local cultures. Degree of ED was categorized as 'none,' 'mild,' 'moderate,' or 'complete.' The age-adjusted prevalence rates of ED among men attending primary care clinics was 57.4% in Nigeria, 63.6% in Egypt, and 80.8% in Pakistan. Older age, diabetes, peptic ulcers, prostate disease, depression-related symptoms, and caffeine consumption were independently associated with increased prevalence of ED, whereas being moderately active to very active at work (hard physical labor) and during leisure time (strenuous exercise) was associated with half the prevalence of moderate-to-complete ED. Our multicultural study demonstrates that in every country studied, high proportions of men older than age 35 have some degree of ED (57-81%). Both severity and prevalence increase consistently with age. Factors associated with ED are similar, but their distribution differs across countries. PMID:12825103

    Previous studies indicated that panic disorder is correlated with erectile dysfunction (ED). The primary aim of this study was to explore the incidence rate of ED among panic disorder patients in an Asian country. The secondary aim was to compare the risk of ED in panic disorder patients that were treated with different kinds of antidepressants, and to explore the possible mechanism between these two disorders. We identified 1393 male patients with newly diagnosed panic disorder from the Taiwan's National Health Insurance Database. Four matched controls per case were selected for the study group by propensity score. After adjusting for age, obesity and comorbidities, the panic disorder patients had a higher hazard ratio of ED diagnosis than the controls, especially among the untreated panic disorder patients. This retrospective dynamic cohort study supports the link between ED and prior panic disorder in a large sample of panic disorder patients. This study points out the need of early antidepressant treatment for panic disorder to prevent further ED. PMID:27497294

    Healthy sexual functioning plays an essential role in maintaining the harmony and happiness in marital life. It provides a media to express love, which is the base for all sorts of creative activities. The absence of this function hampers the marital relationship, leading to frustration and, sometimes, ending in divorce, and causes inadequacy in performing the routine duties. In this study, 53 patients having diabetes mellitus were surveyed to find out the incidence of erectile dysfunction (ED). Considering the high prevalence of the disease and the need to look for alternative medicine, a clinical trial on 44 patients of ED was carried out. These patients were divided into two main groups: diabetic and non-diabetic, and were further divided into two subgroups as trial group and placebo group. In the trial group, Ashvattha Kshirpaka prepared with 10 g powder of its root bark, stem bark, fruit and tender leaf buds was given twice a day. In both the diabetic and the non-diabetic subjects, Ashvattha provided encouraging results on ED as well as on seminal parameters in comparison to the placebo. PMID:22131726

    Aim: To study the effect of intracavemous sodium nitropmsside (SNP), a nitric oxide (NO) donor, on penile erection. Methods: Forty-two patients with erectile dysfunction (ED) were randomly assigned to receive SNP 300μg or the control drugs (papaverine 30mg+phentolamine 1mg) intracavemously crosswise one week apart. The penile length, circumference and hardness after the administration of the experimental and control drugs were assessed and compared statistically. Results: (1)There was no significant difference between the changes in penile length and circumference in the two occasions; (2)In 25 SNP and 28 control cases, the hardness of the penis was scored above 100 as evaluated by the Virag method (P>0.05);(3)The duration of erection in the controls was longer than that in the SNP, but there were three priapism in the controls and not a single one in the SNP; (4)there was no apparent change in the heart rate and blood pressure in both occasions; other side effects were minimal except slight local pain in a few controls. Conclusion: SNP facilitates relaxation of the penile smooth muscle and penile erection without significant side effects. SNP may be used in ED patients that experience pain and priapism with papaverine/phentolamine.(Asian J Androl 2000 Dec;2:301-303)

    Full Text Available This study was designed to determine the antioxidant properties and inhibitory effects of extract from Moringa oleifera leaves on angiotensin-I-converting enzyme (ACE and arginase activities in vitro. The extract was prepared and phenolic (total phenols and flavonoid contents, radical (nitric oxide (NO, hydroxyl (OH scavenging abilities, and Fe2+-chelating ability were assessed. Characterization of the phenolic constituents was done via high performance liquid chromatography-diode array detection (HPLC-DAD analysis. Furthermore, the effects of the extract on Fe2+-induced MDA production in rats’ penile tissue homogenate as well as its action on ACE and arginase activities were also determined. The extract scavenged NO∗, OH∗, chelated Fe2+, and inhibited MDA production in a dose-dependent pattern with IC50 values of 1.36, 0.52, and 0.38 mg/mL and 194.23 µg/mL, respectively. Gallic acid, chlorogenic acid, quercetin, and kaempferol were the most abundant phenolic compounds identified in the leaf extract. The extract also inhibited ACE and arginase activities in a dose-dependent pattern and their IC50 values were 303.03 and 159.59 µg/mL, respectively. The phenolic contents, inhibition of ACE, arginase, and Fe2+-induced MDA production, and radical (OH∗, NO∗ scavenging and Fe2+-chelating abilities could be some of the possible mechanisms by which M. oleifera leaves could be used in the treatment and/or management of erectile dysfunction.

    A pathogenic link between erectile dysfunction (ED) and metabolic syndrome (MetS) is now well established. Nonalcoholic steatohepatitis (NASH), the hepatic hallmark of MetS, is regarded as an active player in the pathogenesis of MetS-associated cardiovascular disease (CVD). This study was aimed at evaluating the relationship between MetS-induced NASH and penile dysfunction. We used a non-genomic, high fat diet (HFD)-induced, rabbit model of MetS, and treated HFD rabbits with testosterone (T), with the selective farnesoid X receptor (FXR) agonist obeticholic acid (OCA), or with the anti-TNFα mAb infliximab. Rabbits fed a regular diet were used as controls. Liver histomorphological and gene expression analysis demonstrated NASH in HFD rabbits. Several genes related to inflammation (including TNFα), activation of stellate cells, fibrosis, and lipid metabolism parameters were negatively associated to maximal acetylcholine (Ach)-induced relaxation in penis. When all these putative liver determinants of penile Ach responsiveness were tested as covariates in a multivariate model, only the association between hepatic TNFα expression and Ach response was confirmed. Accordingly, circulating levels of TNFα were increased 15-fold in HFD rabbits. T and OCA dosing in HFD rabbits both reduced TNFα liver expression and plasma levels, with a parallel increase of penile eNOS expression and responsiveness to Ach. Also neutralization of TNFα with infliximab treatment fully normalized HFD-induced hypo-responsiveness to Ach, as well as responsiveness to vardenafil, a phosphodiesterase type 5 inhibitor. Thus, MetS-induced NASH in HFD rabbits plays an active role in the pathogenesis of ED, likely through TNFα, as indicated by treatments reducing liver and circulating TNFα levels (T or OCA), or neutralizing TNFα action (infliximab), which significantly improve penile responsiveness to Ach in HFD rabbits.

    Objective To investigate the effect of early chronic tadalafil administration on erectile dysfunction after cavernous nerve (CN) injury in the rat model. Methods Using the CN crush injury model, animals were divided into four groups: no CN injury (sham), bilateral CN injury exposed to either no tadalafil (control) or tadalafil at a dose (2 mg/kg) daily postoperation for 4 weeks, and normal group. At the time point, we assessed erectile function by apomorphine test, measurement of maximum intracavernosal pressure (ICP)/mean arterial pressure (MAP) ratio with major pelvic ganglion (MPG) electrical stimulation. For the histological analyses, the mid-shaft of penis were harvested. Immunohistochemical antibody staining was performed for nNOS and the numbers of nNOS-positive nerve fibers were recorded. Results Penile erection was observed in 50% (6/12) of the rats for (1.13±0.92) times within 30 min in control group, as compared with 0% (0/11) of the rats for (0.00±0.00) times in CN crush group (P0.05), while ICP/MAP ratio after MPG electrical stimulation of control group was significantly higher than that of CN crush group (P<0.05), but significantly lower than that of sham group (P<0.05) and normal group (P<0.05). The numbers of nNOS-positive nerve fibers was significantly larger in control group than in CN crush group (54.11±5.02 vs. 21.34±3.17, P<0.05), but was significantly smaller than that of sham group (76.48±8.24, P<0.05) and normal group (81.09±7.25, P<0.05). Conclusions Early chronic low-dose tadalafil administration on erectile dysfunction after CN injury contributes to restoration of erectile function.

    Sildenafil citrate, a drug used to treat erectile dysfunction, is available in tablet form but has three major problems. First, the drug displays poor aqueous solubility, which delays its onset of action. Second, the drug undergoes extensive first-pass metabolism, resulting in a low (40%) bioavailability. Third, the gastrointestinal effects of sildenafil citrate include dyspepsia and a burning sensation. The objective of this study was to prepare sildenafil citrate using a fast orodissolvable film (ODF) containing the drug in a solid dispersion (SD) to mitigate the abovementioned problems. The solubility of sildenafil citrate in β-cyclodextrin derivatives was estimated, and SDs were prepared and characterized. To develop an ODF that disintegrates rapidly and releases the maximum amount of sildenafil citrate, a 3(3) Box-Behnken experimental design was used to estimate the effects of different concentrations of film forming polymer (X1), the film modifier (X2), and the plasticizer (X3) on the responses, i.e. the disintegration time (Y1) and the amount of drug released (Y2). Pharmacokinetic studies with the optimized (ODF) were conducted on human volunteers. SD prepared using hydroxybutyl-β-cyclodextrin enhanced the solubility of sildenafil citrate by more than eightfold. The Y1 for the optimized ODF was 89 seconds, and the Y2 was 86%; this formula also exhibited a rapid onset of action, and its bioavailability was enhanced by 2.25-fold compared with that of the marketed tablet. The ODF is a promising formulation for sildenafil citrate that results in higher solubility, a rapid onset of action, and enhanced systemic bioavailability.

    The purpose of this study was to determine the incidence rate of prostate cancer among men with erectile dysfunction (ED) treated with phosphodiesterase type 5 inhibitors (PDE-5i) over a 7-year period vs.men with ED of the same age and with similar risk factors who were not treated with PDE-5i.In a retrospective review of electronic medical records and billing databases between the years 2000 and 2006,men with ED between the ages of 50 and 69 years and no history of prostate cancer prior to 2000 were identified.These individuals were divided into two groups:2362 men who had treatment with PDE-5i,and 2612 men who did not have treatment.Demographic data in each group were compared.During the study period,97 (4.1%) men with ED treated with PDE-5i were diagnosed with prostate cancer compared with 258 (9.9%) men with ED in the non-treated group (P<00001).A higher percentage of African Americans were treated with PDE-5i vs.those who were not (10.5% vs.7.1%; P<0.0001).The PDE-5i group had lower documented diagnosis of elevated prostate-specific antigen (10.0% vs.13.1%; P=0.0008) and higher percentage of benign prostatic hyperplasia (38.4% vs.35.1%; P=0.0149).Men with ED treated with PDE-5i tended to have less chance (adjusted odds ratio:0.4; 95% confidence intervals:0.3-0.5; P<0.0001) of having prostate cancer.Our data suggest that men with ED treated with PDE-5i tended to have less of a chance of being diagnosed with prostate cancer.Further research is warranted.

    Aim:To determine the age-adjusted prevalence of erectile dysfunction (ED) in 3 big cities of China and to explore its potential sociodemographic, medical and lifestyle correlates. Methods: A crosssectional, population-based survey was conducted in three cities of China. Structured questionnaires were administered to 2 226 men, aged 20-86 years, by trained interviewers. Results: The age-adjusted prevalence of ED was 28.34% (mild 15.99%,moderate 7.14%, severe 5.21%). In the men above 40, the prevalence was 40.2%. Age was positively correlated with ED (P<0.01). Education was negatively correlated with ED (P<0.01). Spouse companionship, living condition were positively correlated with ED (P<0.01). Histories of cardiovascular disease, diabetes, and hyperlipidemia were positively correlated with ED (P<0.01). Cigarette smoking was not correlated with ED (P>0.05), while the cigaretteconsumption and duration were positively correlated with ED (P<0.01). Alcohol drinking is negatively correlated with ED (P<0.01). The duration of drinking was positively correlated with ED (P<0.01). Weekly alcohol consumption was not correlated with ED (P>0.05). Conclusion: The prevalence of ED increased with age. Cardiovascular disease, diabetes and hyperlipidemia were positively correlated with the increased prevalence. Sociodemographic and lifestyle factors, such as education, spouse companionship, living condition, cigarette and alcohol consumption or duration also have association with the prevalence of ED.

    To evaluate the usefulness of maximal blood flow volume (MBFV) measured by duplex ultrasonography (US) compared with penile tumescence measured by RigiScan in the diagnosis of arteriogenic erectile dysfunction (ED). This study included twenty six patients who performed both RigiScan and duplex US after intracorporeal injection of Prostaglandin EL. We measured tumescences of penile tip and base using RigiScan and maximal arterial diameter (MAD) and peak systolic velocity (PSV) using a 7 MHz color Doppler unit. MBFV was defined as (MAD/2){sup 2} X pi X PSV. Based on normal value, we compared MAD and MBFV, and PSV and MBFV and the correlations of each measurements were evaluated with Spearman's correlation analysis. The level of significance was P<0.05. The results between MAD and MBFV, and PSV ad MBFV based on normal values were similar, respectively. Tumescences of penile tip and base were significantly correlated with MAD (r=0.409, r=0.52, p<0.05), and PSV (r=0.565, r=0.396, p<0.05). MBFV was also significantly correlated with tumescences od penile tip and base (r=0.502, r=0.563, p<0.05). In 4 patients with abnormal MAD and normal PSV, 3 had abnormal MBFV and 1 had normal MBFV. All 3 patients with abnormal MBFV had abnormal penile tumescence and 1 patients with normal MBFV had normal tumescence. One patients with normal MAD and abnormal PSV had abnormal MBFV and penile tumescence. In our study, MBFV was accurate in the diagnosis of arteriogenic ED. Moreover, MBFV was usefulness in the diagnosis of arteriogenic ED as it could explain the case where MAD and PSV are not accoded.

    We aimed to evaluate the efficacy of oral therapy with alga Ecklonia bicyclis, Tribulus terrestris, and glucosamine oligosaccharide (Tradamix TX1000) in patients with erectile dysfunction (ED) at 3 months of follow-up. From January 2013 to September 2013, 177 patients diagnosed with mild-moderate ED (IIEF-EF < 26) were enrolled in this multicenter, single-blinded, placebo-controlled study and randomized in Group A (Tradamix, n = 87) and Group B (placebo, n = 90). Penile color Doppler ultrasound measures, IIEF-15 questionnaire, male sexual health questionnaire-ejaculation disorder (MSHQ-EjD), and sexual quality of life (SQoL-M) were collected. We observed significant changes of the IIEF-15 in Group A (mean difference: 11.54; P < 0.05) at 3 months versus Group B (P < 0.05). PSV (P < 0.05), IIEF-intercourse satisfaction (P < 0.05), IIEF-orgasmic function (mean P < 0.05), IIEF-sexual desire (P < 0.05), IIEF-overall satisfaction (P < 0.05), MSHQ-EjD (mean difference: 1.21; P < 0.05), and SQoL-M (mean difference: 10.2; P < 0.05) were significantly changed in Group A versus baseline and Group B. Patients with moderate arterial dysfunction showed significant increase of PSV (P < 0.05), IIEF-EF (P < 0.05), MSHQ-EjD (P < 0.05), and SQoL-M (P < 0.05) in Group A. Therapy with Tradamix improves erectile and ejaculation function and sexual quality of life in patients with mild-moderate ED and in particular for those with moderate arterial dysfunction.

  16. Randomised, placebo-controlled, crossover trial of sildenafil citrate in the treatment of erectile dysfunction following external beam radiation treatment of prostate cancer

    International Nuclear Information System (INIS)

    Erectile dysfunction (ED) commonly affects the quality of life of men after treatment of prostate cancer. We conducted a placebo-controlled, crossover randomised trial to assess the efficacy and tolerability of sildenafil citrate in the treatment of ED developing after external beam radiation treatment (EBRT) of localized prostate cancer. Sixty-six patients who had developed ED following radiation treatment agreed to participate and were allocated to sildenafil or placebo to be taken prior to four sexual attempts. In the crossover period, subjects received the alternative tablet for a further four attempts. Allocation was centrally randomized, and researchers and patients were both blinded to the trial arm. Efficacy was assessed using the International Index of Erectile Function (IIEF) questionnaire and with a separate global efficacy question. Forty-three subjects completed the study. There was a significant increase in mean scores from baseline for all domains of the IIEF with sildenafil compared with placebo (P < 0.001). Affirmative response to the global efficacy question was more common after taking sildenafil compared with placebo. In approximately half of the patients, the improvement in the erectile function domain score corresponded to a moderate improvement in ED (e.g. success ‘sometimes’ to ‘most times’). Sildenafil was associated with mild flushing, nasal stuffiness or indigestion in 8–10% patients and moderate flushing in 10%. The current study adds to the evidence that phosphodiesterase inhibitors are an effective and well-tolerated treatment for ED after EBRT for prostate cancer.

    Erectile dysfunction (ED) following transperineal prostate biopsy (TPB) was prospectively evaluated. From January 2011 to January 2014, 1050 patients were submitted to TPB: 18 core (extended TPB) in 610 cases, 28 core (saturation TPB) in 360 cases and 32 core (saturation plus magnetic resonance imaging (MRI) targeted TPB) in 210 cases. The indications for biopsy were increasing prostate-specific antigen (PSA) or PSA>10 ng ml(-1). All patients were prospectively evaluated with the 5-item version of the International Index of Erectile Function (IIEF-5) at time zero and at 1, 3 and 6 months from TPB. Prostate cancer was diagnosed in 385/1050 (36.6%) patients; 560 men (350 vs 110 vs 100) having benign histology and normal sexual activity also completed the study. Overall, IEEF-5 score at time zero and at 1, 3 and 6 months did not significantly worsen (P>0.05); in detail, at 1 month from biopsy 15 extended TPB (4.2%) vs 7 saturation TPB (6.4%) vs 7 saturation plus MRI targeted TPB (7%) men referred mild ED that disappeared after 3 months. Irrespective of method (18 vs 28 vs 32 core) TPB did not significantly worsen erectile function at 3-6 months from the procedure. PMID:26289906

    ABSTRACT Introduction: We investigate the effect of active peptide from Urechis unicinctus (UU) by high temperature/pressure and ultra-wave assisted lysis on erectile dysfunction in streptozotocin-induced diabetic rats. Materials and Methods: Forty 12-week-old Sprague-Dawley rats were used in this study. Diabetes was induced by a one-time intraperitoneal injection of streptozotocin (50mg/kg). One week later, the diabetic rats were randomly divided into four groups: normal control, untreated diabetes control, and groups treated with 100 or 500mg/kg/d UU peptide. Rats were fed with UU peptide by intragastric administration for 8 weeks. After 8 weeks, penile hemodynamic function was evaluated in all groups by measuring the intracavernosal pressure after electrostimulating the cavernous nerve. Nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) activities were measured and endothelial nitric oxide synthase (eNOS) and neuronal NOS (nNOS) protein expression was determined by Western blot. Results: Maximum intracavernosal pressure in diabetic control rats decreased significantly compared to normal control rats, and was increased significantly compared to untreated diabetic rats after UU peptide supplementation. Treatment with the higher dose of UU peptide significantly increased the NO and cGMP levels compared with the diabetic control group. Decreased activity and expression eNOS and nNOS were found in the diabetic rats compared with the normal control group. Decreased eNOS and nNOS in diabetic rats were improved by UU peptide administration. Conclusions: Active peptide from UU ameliorates erectile function in a streptozotocin induced diabetic rat model of erectile dysfunction. PMID:27564297

    Background Erectile dysfunction (ED) is a common impairment among older men, and the prevalence rates increase sharply after age of 60 years. Most studies have focused on the prevalence rate or dangerouse factors. The aim of this study was to investigate the basic epidemiologic data about ED patients with different ED courses. The purpose of this researth was to understand the therapeutic effect of phosphodiesterase type 5 inhibitor (PDE5-1) and see how and why the ED course impact the progress of ED and the therapeutic effect of PDE5-1 treatment.Methods From June 2008 to June 2009, 4252 questionnaires (Quality of Erection Questionnaire, QEQ) were gathered from 46 centers by urology or andrology doctors all around China. Patients with ED (age > 20 years) filled in first half of the questionnaires when they came for the first time, and then completed the second half 4 weeks after PDE5-1 therapy.Results ED courses of most patients were less than 5 years (<5 years, 74.0%; 5-10 years 20.8%; >10 years, 5.2%). As ED course increasing, the incidence of the risk factors of ED, such as smoking, drinking, hypertension, diabetes, heart disease and hyperlipidemia also increase (P ≤0.01). PDE5-1 was effective in improving the quality of sexual activities (P ≤0.01). Administration of PDE5-1 improves satisfaction, enjoyment and frequency of sexual activities. The longer the ED course, the worse the therapeutic effect (<5 years, 96.1%; 5-10 years, 94.9%; >10 years, 89.0%) (P<0.01).Conclusions The ED course greatly affected the therapeutic effect of PDE5-1, the patients with ED should consult doctor at early stage of the disease. Admistration of PDE5-1 effectively improves the penile erection and the quality of sexual life of the patients hence should be considered as first-line medicine in the treatment of ED.

    Erectile dysfunction is common among individuals with Parkinson's disease, but it is unknown whether it precedes the onset of the classic features of Parkinson's disease. To address this question, the authors examined whether erectile dysfunction was associated with Parkinson's disease risk in the Health Professionals Follow-up Study. Analyses included 32,616 men free of Parkinson's disease at baseline in 1986 who in 2000 completed a retrospective questionnaire with questions on erectile dysfunction in different time periods. Relative risks were computed using Cox proportional hazards models adjusting for age, smoking, caffeine intake, history of diabetes, and other covariates. Among men who reported their erectile function before 1986, 200 were diagnosed with Parkinson's disease during 1986-2002. Men with erectile dysfunction before 1986 were 3.8 times more likely to develop Parkinson's disease during the follow-up than were those with very good erectile function (relative risk = 3.8, 95% confidence interval: 2.4, 6.0; p disease were 2.7, 3.7, and 4.0 (95% confidence interval: 1.4, 11.1; p = 0.008) for participants with first onset of erectile dysfunction (before 1986) at 60 or more, 50-59, and less than 50 years of age, respectively, relative to those without erectile dysfunction. In conclusion, in this retrospective analysis in a large cohort of men, the authors observed that erectile dysfunction was associated with a higher risk of developing Parkinson's disease.

    We have done consecutive studies to investigate the effects of impaired lipid metabolism on the contractile and relaxation response of cavernous smooth muscles and to elucidate its pathogenesis: 1 ) incidence of hyperlipidemia in impotent patients; 2) erection response to intmcavemous injection of papaverine in impotent patients with hyperlipidemia; 3) relaxation responses of isolated cavemosal smooth muscles to endothelium-independent and endothelium-dependent vasodilators in impotent patients with hypercholesterolemia or hypertriglyceridemia; 4) involvement of superoxide radical in the impaired endothelium-dependent relaxation of cavernous smooth muscle in hypercholesterolemic rabbits; 5) effects of isolated lipoproteins and triglyceride, combined oxidized LDL plus triglyceride, and combined oxidized LDL plus HDL on contractile and relaxation response of rabbit cavernous smooth muscles; 6) involvement of e-NOS in the impaired endothelium-dependent relaxation of cavernous smooth muscle in hypercholesterolemic rabbit. Hypercholesterolemia may cause impairment of endothelium-dependent relaxation. Oxidized LDL is the major causative cholesterol of the impaired relaxation response. A chain reaction, the production of superoxide radicals and functional impairment of eNOS may be a major cause of the functional impairment in the early stages of hypercholesterolemia.

    Full Text Available The aim of this study was to determine whether adipose derived stem cells (ADSCs expressing vascular endothelial growth factor (VEGF gene can improve endothelial function, recover the impaired VEGF signaling pathway and enhance smooth muscle contents in a rat diabetic erectile dysfunction (DED model. DED rats were induced via intraperitoneal injection of streptozotocin (40 mg/kg, and then screened by apomorphine (100 µg/kg. Five groups were used (n = 12/group-Group 1 (G1: intracavernous injection of lentivirus-VEGF; G2: ADSCs injection; G3: VEGF-expressing ADSCs injection; G4: Phosphate buffered saline injection; G1-G4 were DED rats; G5: normal rats. The mean arterial pressure (MAP and intracavernosal pressure (ICP were measured at days 7 and 28 after the injections. The components of the VEGF system, endothelial, smooth muscle, pericytes markers in cavernoursal tissue were assessed. On day 28 after injection, the group with intracavernosum injection of ADSCs expressing VEGF displayed more efficiently and significantly raised ICP and ICP/MAP (p<0.01 than those with ADSCs or lentivirus-VEGF injection. Western blot and immunofluorescent analysis demonstrated that improved erectile function by ADSCs-VEGF was associated with increased expression of endothelial markers (VEGF, VEGF R1, VEGF R2, eNOS, CD31 and vWF, smooth muscle markers (a-actin and smoothelin, and pericyte markers (CD146 and NG2. ADSCs expressing VEGF produced a therapeutic effect and restored erectile function in diabetic rats by enhancing VEGF-stimulated endothelial function and increasing the contents of smooth muscle and pericytes.

    Diabetes-induced oxidative stress plays a critical role in the mobilisation of endothelial progenitor cells (EPCs) from the bone marrow to the circulation.This study was designed to explore the effects of chronic melatonin administration on the promotion of the mobilisation of EPCs and on the preservation of erectile function in type Ⅰ diabetic rats.Melatonin was administered to streptozotocin-induced type Ⅰdiabetic rats.EPCs levels were determined using flow cytometry,Oxidative stress in the bone marrow was indicated by the levels of superoxide dismutase and malondialdehyde.Erectile function was evaluated by measuring the intracavemous pressure during an electrostimulation of the cavernous nerve.The density of the endothelium and the proportions of smooth muscle and collagen in the corpus cavernosum were determined by immunohistochemistry.The administration of melatonin increased the superoxide dismutase level and decreased the malondiaidehyde level in the bone marrow,This effect was accompanied by an increased level of circulating EPCs in the diabetic rats.The intracavernous pressure to mean arterial pressure ratio of the rats in the treatment group was significantly greater,compared with diabetic control rats.The histological analysis demonstrated an increase in the endothelial density of the corpus cavernosum after the administration of melatonin.However,melatonin treatment did not change the proportions of smooth muscle and collagen in the corpus cavernosum of diabetic rats.Chronic administration of melatonin has a beneficial effect on preventing erectile dysfunction (ED) in type Ⅰ diabetic rats.Promoting the mobilisation of EPCs is one of the possible mechanisms involved in the improvement of ED.

    Full Text Available The effectiveness of phosphodiesterase type 5 inhibitors (PDE5-Is for erectile dysfunction (ED varies considerably among trials, but available studies investigating the factors that affect the effectiveness are few and findings are not consistent. A systematic search was performed in PubMed, Cochrane Library, and EMBASE to identify randomized controlled trials comparing PDE5-Is with placebo for the treatment of ED. The methodological quality of included studies was assessed by the Cochrane Collaboration′s tool for assessing risk of bias. The associations between prespecified study-level factors and effectiveness were tested by a random effects meta-regression model. This study included 93 trials with 26 139 patients. When all PDE5-Is were grouped together, Caucasian ethnicity was associated with 15.636% (95% confidence interval [CI]: 0.858% to 32.579% increase in risk ratio (RR for Global Assessment Questionnaire question-1 (GAQ-1, and 1.473 (95% CI: 0.406 to 2.338 score increase in mean difference (MD for posttreatment International Index of Erectile Function-Erectile Function domain score (IIEF-EF, compared to Asian ethnicity. A one-score increase in baseline IIEF-EF was associated with −5.635% (95% CI: −9.120% to −2.017% reduction in RR for GAQ-1, and −0.229 (95% CI: −0.425 to −0.042 score decrease in MD for posttreatment IIEF-EF. In conclusion, PDE5-Is are more effective in Caucasians than Asians, and in patients with more severe ED.

    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 < 0.05 for both). However, patients taking Maca experienced a more significant increase than those taking placebo (1.6 +/- 1.1 versus 0.5 +/- 0.6, P < 0.001). Both 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 < 0.05). However, only 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 < 0.05). In conclusion, our data support a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED. PMID:19260845

    Erectile dysfunction (ED) is an important worldwide health issue that has a significant negative impact on the quality of life and life satisfaction of both the affected individual and his partner. Here we review the prevalence of ED in Asia, associated factors that may influence sexual attitudes and sexual behaviours, and randomized clinical trials (RCTs) of phosphodiesterase-5 (PDE-5) inhibitors to evaluate the clinical efficacy and safety of PDE-5 inhibitors in Asian men. We searched for English-language articles in MEDLINE and PubMed from January 2000 to September 2010. Our results showed that the overall reported prevalence rate of ED in Asia ranged widely, from 2% to 88%. This finding indicates that ED is a common and major health problem in this region. However, sociocultural and economic factors in Asia prevent people from seeking and obtaining appropriate medical care. We found reports on five kinds of PDE-5 inhibitors for the management of ED: sildenafil, vardenafil, tadalafil, udenafil and mirodenafil. The results of RCTs showed that these five PDE-5 inhibitors are more effective than placebo in improving erectile function in Asian men with ED and that these drugs have similar efficacy and safety profiles.

    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.

    Introduction Bisphenol A (BPA), a suspected reproductive biohazard and endocrine disruptor released from plastics is associated with erectile dysfunction (ED) in occupationally exposed workers. However, in rats, despite the induction of hypogonadism, apoptosis of the penile corporal smooth muscle, fat infiltration into the cavernosal tissue, and changes in global gene expression with the intraperitoneal administration of high dose BPA, ED was not observed. Aims We investigated whether BPA administered orally rather than intraperitoneally to rats for longer periods and lower doses will lead to ED. Main Outcomes Measures ED, histological, and biochemical markers in rat penile tissues. Methods 2.5-month old rats were given drinking water daily without and with BPA at 1 and 0.1 mg/kg/day. Two months later, erectile function was determined by cavernosometry (DIC) and electrical field stimulation (EFS) and serum levels of testosterone (T), estradiol (E2), and BPA were measured. Penile tissue sections were assayed by Masson (smooth muscle (SM)/collagen), Oil Red O (fat), TUNEL (apoptosis), immunohistochemistry for Oct 4 (stem cells), and α-SM actin/ calponin (SM and myofibroblasts), applying quantitative image analysis. Other markers were assayed by western blots. DNA microarrays/microRNA assays defined transcription profiles. Results Orally administered BPA did not affect body weight, but: 1) decreased serum T and E2; 2) reduced the EFS response and increased the DIC drop rate; 3) increased within the corporal tissue the presence of fat, myofibroblasts and apoptosis; 4) lowered the contents of SM and stem cells, but not nerve terminals; and 5) caused alterations of the transcriptional profiles for both mRNA and microRNAs within the penile shaft. Conclusions Long-term exposure of rats to oral BPA,caused a moderate corporal veno-occlusive dysfunction (CVOD), possibly due to alterations within the corporal tissue that pose gene transcriptional changes related to

    Erectile dysfunction (ED) is defined as the inability of the male to attain and/or maintain erection of penis sufficient to permit satisfactory sexual intercourse. Prevalence of impotence in diabetic men is more than 50%. The mechanism of diabetes-induced erectile dysfunction (DIED) is multifactorial, involving many factors. Previous studies focused on the influence of neuropathy and vascular lesions, but endothelial and myogenic disorders played more and more important roles in recent years. Although the treatment methods of DIED are many, drugs and the penis prosthesis implants have become the standard ways at present. Gene delivery vectors have shown a promising perspective, however, there are still some problems which need be solved further in clinical application.%勃起功能障碍(ED)是指不能获得或维持充分勃起以完成令人满意的性交过程.糖尿病患者中50%以上伴有ED,糖尿病性勃起功能障碍(DIED)发病机制复杂,涉及多因素.以往的研究多集中在神经病变和血管病变的影响,近来内皮细胞性及肌源性因素对ED的影响越来越受到重视.目前治疗DIED方法有多种,药物和阴茎假体植入手术在当前还是治疗DIED的标准方式,通过载体转染的基因治疗提供了另一条新的途径,但在临床应用前还需解决一些问题.

    Purpose: To identify single nucleotide polymorphisms (SNPs) associated with development of erectile dysfunction (ED) among prostate cancer patients treated with radiation therapy. Methods and Materials: A 2-stage genome-wide association study was performed. Patients were split randomly into a stage I discovery cohort (132 cases, 103 controls) and a stage II replication cohort (128 cases, 102 controls). The discovery cohort was genotyped using Affymetrix 6.0 genome-wide arrays. The 940 top ranking SNPs selected from the discovery cohort were genotyped in the replication cohort using Illumina iSelect custom SNP arrays. Results: Twelve SNPs identified in the discovery cohort and validated in the replication cohort were associated with development of ED following radiation therapy (Fisher combined P values 2.1 Multiplication-Sign 10{sup -5} to 6.2 Multiplication-Sign 10{sup -4}). Notably, these 12 SNPs lie in or near genes involved in erectile function or other normal cellular functions (adhesion and signaling) rather than DNA damage repair. In a multivariable model including nongenetic risk factors, the odds ratios for these SNPs ranged from 1.6 to 5.6 in the pooled cohort. There was a striking relationship between the cumulative number of SNP risk alleles an individual possessed and ED status (Sommers' D P value = 1.7 Multiplication-Sign 10{sup -29}). A 1-allele increase in cumulative SNP score increased the odds for developing ED by a factor of 2.2 (P value = 2.1 Multiplication-Sign 10{sup -19}). The cumulative SNP score model had a sensitivity of 84% and specificity of 75% for prediction of developing ED at the radiation therapy planning stage. Conclusions: This genome-wide association study identified a set of SNPs that are associated with development of ED following radiation therapy. These candidate genetic predictors warrant more definitive validation in an independent cohort.

    Type 5 phosphodiesterase inhibitors (PDE51s) are well known being effective viathe nitric oxide and cyclic guanosine monophosphate (NO-cGMP) pathway and are widely used in the treatment of diabetic erectile dysfunction (ED).However,it is unclear whether other pathways may be involved in the treatment of diabetic ED with PDE51s.The purpose of this study was to clarify the role of antioxidants in diabetic ED treatment through the long-term administration of PDE51s.Three groups of Sprague-Dawley rats were utilized:Group N,the normal control; Group D,streptozotocin (STZ)-induced diabetic rats as a control; and Group D+T,STZ-induced diabetic rats who received oral administration of tadalafil for 8 weeks.Erectile function was assessed by intracavernous pressure (ICP) and mean arterial pressure (MAP) during electrical stimulation of the cavernous nerve before euthanasia.The levels of malondialdehyde (MDA),superoxide dismutase (SOD) and mitochondrial membrane potential (MMP) of cavernous tissue were assessed by biochemical analysis.The morphology of mitochondria was observed by electron microscopy.The ICP/MAP ratio was higher in Group D+T than in Group D (P<0.05).The levels of MDA decreased and the activities of SOD increased in Group D+T in comparison with Group D (P<0.05).The mitochondrial membrane potential level of cavernous tissue in diabetic rats was partially recovered by tadalafil treatment for 8 weeks.The morphology changes of mitochondria were also remarkably ameliorated in Group D+T.Collectively,the long-term administration of tadalafil in diabetic rats partially reduced oxidative stress lesions of the penis viaa local antioxidative stress pathway.Long-term dosages of tadalafil given once daily beginning soon after the onset of diabetes may aid in preventing rats from developing diabetic ED.

    Chronic inflammation may cause endothelial dysfunction and atherosclerosis, resulting in subsequent erectile dysfunction (ED). We examined the relationship between chronic osteomyelitis, which is a chronic inflammatory disease, and ED. A retrospective cohort study was conducted using data from the National Health Insurance Research Database. After excluding patients osteomyelitis (COM) from 1 January 2000 to 31 December 2011 were identified for the study. The non-osteomyelitis comparison cohort consisted of 2706 male participants. The incidence of ED was 2.66-fold higher in the COM cohort than in the non-osteomyelitis cohort (4.01 vs 1.51 per 10 000 person-years). After adjusting for age and comorbidities of coronary heart disease, hypertension, hyperlipidemia, depression, stroke, diabetes, peripheral vascular disease, chronic kidney disease, chronic obstructive pulmonary disease and asthma, the patients with COM had a 2.82-fold risk of ED (95% confidence interval=1.44-5.56). The incidence of ED increased with that of comorbidities in both cohorts. The highest hazard ratio was in patients between 40 and 59 years of age who had COM. Our data showed, for the first time, that COM is a possible risk factor for the development of ED. PMID:27169492

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS/SIGNIFICANCE: 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 INTRODUCTION: The corpora cavernosa are cylindrical vessels containing fluid under pressure. Thus, if cavernous wall resistance decreases, the radius increases and internal pressure decreases (LaPlace's law. We reasoned that if we decrease the corpus cavernosum radius, by excising a strip from each tunica albuginea, intracavernous pressure would increase during erection. MATERIALS AND METHODS: We treated with this procedure, four patients (mean age 41.5 with long-standing erectile dysfunction due to veno-occlusive dysfunction, non-responders to phosphodiesterase-5 inhibitors and intracavernous PGE1 injection. RESULTS: Two months post-surgery, intracavernous PGE1 (40 mcg induced a satisfactory erection in two patients and a 45% and 58% tumescence in the other two. PGE1 responders also responded to 100 mg sildenafil. After 100 mg sildenafil and 20 mg tadalafil, the two non-responders had erections that enabled penetration but were short lasting. CONCLUSION: The procedure described could be more effective than cavernous revascularization operations. The results seem to confirm the mathematical assumptions.

    largely on the release of nitric oxide (NO by vascular endothelium. Insulin resistance (IR, present in most subjects who have obesity, metabolic syndrome (MS or type 2 diabetes mellitus (DM2 is a metabolic abnormality that produces endothelial dysfunction determined by minor synthesis and release of NO. Treatment with metformin improves erectile function in mice with erectile dysfunction (ED and IR. Aims: To evaluate in ED patients: 1 the presence of IR; 2 the degree of severity of ED according to the presence of IR; 3 the effect of treatment with metformin on erectile function in patients with ED and IR. Methods: Prospective, randomized, controlled, double-blind placebo study. We included 81 patients with ED and 20 men without ED (control group. Exclusion criteria: pharmacologic, anatomic or endocrine ED (hypogonadism or hyperprolactinemia, DM2, prior prostatic surgery or chronic illnesses. The erectile function was rated according the International Index of Erectile Function 5. IR was measerud by HOMA index. Thirty patients with ED, IR and poor response to sildenafil were randomized to receive metformin or placebo. Results: Patients with ED had higher HOMA index versus control group: 4.9 ± 2.8 versus 3.6 ± 2.6, p=0.03. The prevalence of IR was higher in ED group versus control group: 77.7% versus 45.0%, p=0.008. We found a negative correlation between HOMA and IIEF-5: r:-0.21, p=0.04. Patients with ED and IR (n=62 had lower IIEF-5 score when compared with those without IR (n=19: 13.6 ± 4.3 versus 16.0 ± 3.1, p=0.04. After treatment with metformin patients with ED showed a significant increase in IIEF-5 score and a significant decrease in HOMA index both at 2 and 4 months of treatment. Changes in the IIEF-5 score and HOMA index were not observed in patients with ED receiving placebo. Conclusion: Our findings suggest that endothelial dysfunction caused by IR could be one of the pathophysiologial mechanisms of ED. Treatment with metformin in patients with ED reduces IR

    Erectile dysfunction (ED) has been found to frequently precedes the onset of coronary artery disease (CAD), representing an early marker of subclinical vascular disease, included CAD. Its recognition is, therefore, a “window opportunity” to prevent a coronary event by aggressive treatment of cardiovascular risk factors. The artery size hypothesis (ASH) has been proposed as a putative mechanism to explain the relationship between ED and CAD. Since atherosclerosis is a systemic disorder all major vascular beds should be affected to the same extent. However, symptoms at different points in the system rarely become evident at the same time. This is likely the result of smaller vessels (i.e. the penile artery) being able to less well tolerate the same amount of plaque when compared with larger ones (i.e. the coronary artery). If true, ED will develop before CAD. We present a case in which ED developed after a coronary event yet before a coronary recurrence potentially representing a late marker of vascular progression. Reasons for this unusual sequence are discussed as they might still fit the ASH.

  10. What do most erectile dysfunction guidelines have in common? No evidence-based discussion or recommendation of heart-healthy lifestyle changes and/or Panax ginseng

    Sexual health or erectile dysfunction (ED) state of the art guidelines provide a thorough overview of conventional prescription or other notable extrinsic treatment options.Yet,over the past 10-15 years,a plethora of international researchers have established that individual and comprehensive lifestyle changes can prevent and potentially improve ED.We review the lifestyle evidence that should equate to grade A or level 1 evidence recommendations for ED.We also review the evidence for Panax ginseng,an over-the-counter (OTC) dietary supplement with a 35-year history of laboratory investigations,multiple positive randomized trials over approximately 15 years and several independent meta-analyses and systematic reviews.Perhaps it is time to at least discuss and even emphasize lifestyle and other non-conventional interventions in ED guidelines so that patients can explore a diversity of potentially synergistic choices with their physicians and can improve their quality and quantity of life.Ignoring the consistent,positive data on lifestyle modifications in ED guidelines,for example,is tantamount to ignoring diet and lifestyle changes to reduce the risk of or ameliorate cardiovascular diseases.

    Current available treatment options for erectile dysfunction (ED) are effective but not without failure and/or side effects. Although the development of phosphodiesterase type 5 (PDE5) inhibitors (I.e. Sildenafil, tadalafil and vardenafil) has revolutionized the treatment of ED, these oral medications require on-demand access and are not as effective in treating ED related to diabetic, post-prostatectomy and severe veno-occlusive disease states. Improvement in the treatment of ED is dependent on understanding the regulation of human corporal smooth muscle tone and on the identification of relevant molecular targets. Future ED therapies might consider the application of molecular technologies such as gene therapy. As a potential therapeutic tool, gene therapy might provide an effective and specific means for altering intracavernous pressure "on demand" without affecting resting penile function. However, the safety of gene therapy remains a major hurdle to overcome before being accepted as a mainstream treatment for ED. Gene therapy aims to cure the underlying conditions in ED, including fibrosis. Furthermore, gene therapy might help prolong the efficacy of the PDE5 inhibitors by improving penile nitric oxide bioactivity. It is feasible to apply gene therapy to the penis because of its location and accessibility, low penile circulatory flow in the flaccid state and the presence of endothelial lined (lacunar) spaces. This review provides a brief insight of the current role of gene therapy in the management of ED.

    We designed this study to compare the efficacy of using a three-dimension head mounted displayer (3-D HMD) and a conventional monitor in audio-visual sexual stimulation (AVSS) in differential diagnosis of psychogenic from organic erectile dysfunction (ED). Three groups of subjects such as psychogenic ED, organic ED, and healthy control received the evaluation. The change of penile tumescence in AVSS was monitored with Nocturnal Electrobioimpedance Volumetric Assessment and sexual arousal after AVSS was assessed by a simple question as being good, fair, or poor. Both the group of healthy control and psychogenic ED demonstrated a significantly higher rate of normal response in penile tumescence (P<0.05) and a significantly higher level of sexual arousal (P<0.05) if stimulated with 3-D HMD than conventional monitor. In the group of organic ED, even using 3-D HMD in AVSS could not give rise to a better response in both assessments. Therefore, we conclude that using a 3-D HMD in AVSS helps more to differentiate psychogenic from organic ED than a conventional monitor in AVSS.

    Full Text Available Male erectile dysfunction (ED is an important issue worldwide occurring in 5-69% of men in community-based studies. It is more common in patients with chronic kidney disease (CKD and those on peritoneal as well as hemodialysis (HD, occurring in more than 80% of patients. In Sudan, there is no pre-vious report on ED among patients with CKD. A cross-sectional study was done to determine the prevalence of ED and its associated risk factors among Sudanese CKD patients on HD and those who underwent renal transplant. This was conducted in Khartoum, Sudan from October 2005 to July 2006 including all married men who were on maintenance HD for more than three months and all married men who had received renal transplantation at least three months earlier. Single, divorced/separated men, those whose wives were living away, those who were bed-bound and those with cognitive impairment were also excluded. After obtaining consent for participation, demographic and clinical data were collected by using anonymous questionnaires and the Arabic version of International Index of Erectile Function (IIEF; the Egyptian version. Patients who did not participate in full and proper manner were considered as "non-responders." A total of 146 patients, 106 HD patients, and 40 renal transplant recipients completed the IIEF questionnaire. Non-responders constituted 43.7% and 54.5% of HD and transplant recipient patients, respectively. Blood samples were taken after completion of the IIEF questionnaire to determine the required investigations. ED prevalence was high among our study patients, 83% among the HD patients and 67.5% among the renal transplant recipients. Univariate analysis showed that there was a trend, although non-significant, of older age being associated with ED in both groups. Similar association was seen in those who were under-dialyzed in the HD group and DM in the transplant recipient group. Previous history of ED was significantly associated with current

    2013-01-01

    Introduction Individuals with erectile dysfunction have been shown to display lower heart rate variability (HRV), suggesting dysregulation of cardiac autonomic function. No studies have explored whether HRV is predictive of erectile response among men with clinically normal erectile function. Aim To examine associations between resting HRV and objective measures of genital response (i.e., resting penile circumference; erectile tumescence) and self-reported sexual function. Methods The sample comprised 59 male community volunteers (mean age = 20.15 years; SD = 2.52) selected from the control conditions of two previously published studies. Participants reported erectile function in the normal range (scoring ≥ 26 on the International Index of Erectile Function [IIEF]) and had no history of cardiovascular disease or myocardial infarct. During a laboratory visit, self-report, anthropometric, cardiovascular, and electrocardiographic data were assessed, as well as resting penile circumference and erectile tumescence in response to viewing an erotic film. Main Outcome Measures Resting penile responses, erectile tumescence (circumferential change via penile plethysmography), self-reported sexual function per the IIEF, and both time-domain (standard deviation of beat-to-beat [NN] intervals [SDNN], square root of the mean squared difference of successive NN intervals [RMSSD], and percent of NN intervals for which successive heartbeat intervals differed by at least 50 msec [pNN50]) and frequency-domain (low frequency [LF], high frequency [HF], LF/HF ratio) parameters of HRV were assessed. Results Higher resting HF power and lower resting LF/HF ratio were associated with greater erectile tumescence. There were marginally significant positive associations between mean NN interval and pNN50 and penile tumescence. HRV was not associated with self-reported sexual function or with resting penile circumference. Conclusions Results suggested that, among men without erectile

Given little real-world evidence on treatment use or satisfaction with treatment for concurrent BPH/LUTS and/or ED, this study examined medication regimens and differences in satisfaction and health-related quality of life (HRQoL) across regimens among men with concurrent BPH and ED. Methods A cross-sectional study was conducted using an Internet survey of participants recruited through an online panel. Respondents (N=736) included men (aged ≥40) who self-reported a diagnosis of both ED and BPH with prescription treatment in the past 3 months for both conditions. Treatment satisfaction (eg, convenience and ease of planning) and HRQoL (eg, International Prostate Symptom Score, sleep quality) were self-reported. Generalized linear models examined the association of regimen with treatment satisfaction and HRQoL, adjusting for covariates (eg, age and comorbidities). Results Final analyses included participants (N=507) using: tadalafil once-daily monotherapy (22%), tadalafil for ED with an alternate BPH therapy (36%), or another phosphodiesterase type-5 inhibitor (PDE5-I) combination (41%). These groups represented the major categories of treatment regimens found in the sample, excluded participants with ambiguous regimens, and were aligned with current standard of care for BPH and ED. Overall, patients reported moderate levels of BPH and a moderate-to-severe degree of ED. Tadalafil monotherapy patients had higher treatment satisfaction scores and greater reported ease of treatment planning and convenience than PDE5-I combination patients. No significant intergroup differences were found on HRQoL. Conclusion A majority of patients (59%) took tadalafil alone or in combination for BPH/ED treatment. Tadalafil monotherapy patients reported greater treatment satisfaction than patients taking PDE5

    The pathogenesis of diabetic erectile dysfunction ( DED) is complicated. Erection related smooth muscle cells, endothelial cells and nerve tissues are all impaired. Bone marrow derived mesenchymal stem cells are a kind of somatic stem cells, which have the potential to differentiate into many tissues cells. Also, they can secrete kinds of growth factors which improve the repair of tissues. Transplantation of bone marrow derived mesenchymal stem cells could be a new method to repair DED.%糖尿病性勃起功能障碍(diabetic erectile dysfunction,DED)发病机制复杂,勃起相关的平滑肌细胞、内皮细胞及神经组织均受到损伤.骨髓间充质干细胞(bone marrow derived mesenchymal stem cell,BM-MSC)是一种骨髓来源的成体干细胞,它具有向多种组织细胞分化的潜能,并能够分泌多种促进组织修复的生长因子.BM-MSC移植可成为治疗DED的一种新方法.

    One of the important objectives of this manuscript is to focus on the place of erectile dysfunction as an important factor for infertility. The review is about correlating the indiscriminate use of pesticides and to find out and highlight the evidences for mechanism of action of these pesticides for erectile dysfunction and find out the most used and most dangerous pesticide from erectile dysfunction point of view. The review suggests that erectile dysfunction is having a significant place as a causal factor for infertility. Study infers that pesticides are having multiple mechanisms of action through which these cause erectile dysfunction. It also reflects that acetamiprid is having most devastating effect causing erectile dysfunction as it acts through multiple inhibitory pathways. The review successfully highlights the indiscriminate regional use of pesticides.

    The pathophysiology of diabetes is multifactorial and no single etiology is at the forefront. The proposed mechanisms of erectile dysfunction (ED) in diabetic patients includes elevated advanced glycation end-products (AGEs) and increased levels of oxygen free radicals, impaired nitric oxide (NO) synthesis, increased endothelin B receptor binding sites and ultrastructural changes, upregulated RhoA/Rho-kinase pathway, NO-dependent selective nitrergic nerve degeneration and impaired cyclic guanosine monophosphate (cGMP)-dependent kinase-1 (PKG-1). The treatment of diabetic ED is multimodal. Treatment of the underlying hyperglycemia and comorbidities is of utmost importance to prevent or halt the progression of the disease. The peripherally acting oral phosphodiesterase type 5 (PDE5) inhibitors are the mainstay of oral medical treatment of ED in diabetics. Vacuum erection devices are an additional treatment as a non-invasive treatment option. Local administration of vasoactive medication via urethral suppository or intracorporal injection can be effective with minimal side-effects. Patients with irreversible damage of the erectile mechanism are candidates for penile implantation. Future strategies in the evolution of the treatment of ED are aimed at correcting or treating the underlying mechanisms of ED. With an appropriate vector, researchers have been able to transfect diabetic animals with agents such as neurotrophic factors and nitric oxide synthase (NOS). Further studies in gene therapy are needed to fully ascertain its safety and utility in humans.

    To investigate the change of erection duration measured by stopwatch with flexible dose vardenafil administered for 8 weeks in subjects with erectile dysfunction (ED). Effect of levitra on sustenance of erection was an open-label, prospective, multicenter and single-arm study designed to measure the duration of erection in men with ED receiving a flexible dose of vardenafil over an 8-week treatment period. Patients were instructed to take vardenafil 10 mg 60 min before attempting the intercourse. Vardenfil could be increased to 20 mg or decreased to 5 mg concerning patients' efficacy and safety. Following the initial screening, patients entered a 4-week treatment-free run-in phase and 8-week treatment period, during which they were instructed to attempt intercourse at least four times on four separate days. A total of 95 men were enrolled in 10 centers. After the 8 weeks treatment, the mean duration of erection leading to successful intercourse was statistically superior when patients were treated with vardenafil. After an 8-week treatment, the duration of erection leading to successful intercourse was 9.39 min. There were significant benefits with vardenafil in all domains of International Index of Erectile Function. Secondary efficacy end points included success rate of penetration, maintaining erection, ejaculation and satisfaction were superior when patients were treated with vardenafil. There was a significant correlation between duration of erection with other sexual factors. Also partner's sexual satisfaction was increased with vardenafil. Most adverse events were mild or moderate in severity. Vardenafil was safe and well tolerated. Vardenafil therapy provided a statistically superior duration of erection leading to successful intercourse in men with ED with female partner. PMID:25471318

    Aim: To examine the treatment efficacy of Korean Red Ginseng (KRG) in impotent men with erectile dysfunction (ED). Methods: A total of 60 patients presenting mild or mild to moderate ED were enrolled in a double-blind,placebo-controlled study in which the efficacies of KRG and a placebo were compared. The patients received either 1 000 mg (3 times daily) of KRG or a placebo. Results: The five-item version of the International Index of Erectile Function (IIEF-5) score after the treatment was significantly higher in the KRG group compared with that before the treatment (from 16.4 ± 2.9 to 21.0 ± 6.3, P < 0.0001). In contrast, there was no difference before and after the treatment in the placebo group (from 17.0 ± 3.1 to 17.7 ± 5.6, P > 0.05). In the KRG group, 20 patients (66.6%),reported improved erection, significant in the global efficacy question (P < 0.01); in the placebo group there was no significance. Scores on questions 2 (rigidity), 3 (penetration), 4 and 5 (maintenance), were significantly higher for KRG than those for the placebo when those questions were answered after 12 weeks of each treatment (P < 0.01).When the score in the KRG group was compared to the placebo group after the treatment, there was a significant improvement in total score (IIEF-5 score) in questions 3 and 5 for the KRG-treated group (P < 0.001 and P < 0.0001,respectively). The levels of serum testosterone, prolactine and cholesterol after the treatment were not statistically significant different between the KRG and the placebo group (P > 0.05). Conclusion: Our data show that KRG can be an effective alternative to the invasive approaches for treating male ED.

    Aim:To determine whether adenoviral gene transfer of insulin like growth factor- 1 (IGF- 1) to the penis of streptozotocin (STZ)-induced diabetic rats could improve erectile capacity. Methods: The STZ diabetic rats were transfected with AdCMV-βgal or AdCMV-IGF-1. These rats underwent cavernous nerve stimulation to assess erectile function and their responses were compared with those of age-matched control rats 1 to 2 days after transfection. In control and transfected STZ diabetic rats, IGF-1 expression were examined by reverse transcription polymerase chain reaction (RT-PCR), Western blot and histology. The penis β-galactosidase activity and localization of the STZ diabetic rats were also determined. Results: One to two days after transfection, the β-galactosidase was found in the smooth muscle cells of the diabetic rat penis transfected with AdCMV-βgal. One to 2 days after administration of AdCMVIGF-1, the cavernosal pressure, as determined by the ratio of maximal intracavernous pressure-to-mean arterial pressure (ICP/MAP) and total intracavernous pressure (ICP), was increased in response to cavernous nerve stimulation.Transgene expression was confirmed by RT-PCR, Western blot and histology. Conclusion: Gene transfer of IGF-1 significantly increased erectile function in the STZ diabetic rats. These results suggest that in vivo gene transfer of IGF-1 might be a new therapeutic intervention for the treatment of erectile dysfunction (ED) in the STZ diabetic rats.

    Initiation of ED treatment with a particular PDE5I may influence treatment-adherence and other outcomes. In this multicenter, open-label study, men with ED, naïve to PDE5I, were randomized to tadalafil 5 mg once-a-day (OaD; N=257), 10 mg on demand (PRN; N = 252) or sildenafil-citrate (sildenafil) 50 mg PRN (N = 261) for 8 weeks (dose adjustments allowed), followed by 16 weeks of pragmatic treatment (switching between PDE5I allowed). Primary outcomes (treatment-adherence) were reported previously. Here, we report effects on: Psychological and Interpersonal Relationship Scales, Self-Esteem and Relationship (SEAR) questionnaire, ED Inventory of Treatment Satisfaction (EDITS), International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP) and Global Assessment Questions (GAQ). Mixed-model for repeated measures and analysis of covariance were used to analyze changes from baseline; GAQ-responses were evaluated by logistic regression. Analyses were adjusted for treatment, country, ED-severity, baseline and baseline-by-treatment interaction. Patients randomized to tadalafil OaD or PRN reported greater improvement (least-square mean (s.e.) change) in Sexual Self-Confidence (OaD +0.90 (0.048), PRN +0.93 (0.050), vs +0.73 (0.049); P=0.006 and P=0.001) and Spontaneity (OaD +0.11 (0.035), PRN +0.13 (0.035), vs +0.02 (0.035); P = 0.044 and P = 0.010) compared with sildenafil.

    Aim:To test the hypothesis that sildenafil (50 mg nightly for one year) can improve spontaneous erectile function (EF) in men with mild-to-moderate arteriogenic erectile dysfunction (ED) responsive to erectogenic treatment. Methods:In a prospective open-label trial, 112 men with ED were randomized to sildenafil 50 mg nightly or sildenafil 50 or 100 mg as needed for 12 months, followed by one-month and 6-month non-medicated periods. Non-randomized,non-medicated men with ED were also assessed. The EF domain of the International Index of Erectile Function (IIEF EF) and the peak systolic velocity (PSV) of penile cavernous arteries were used to measure the efficacy. Results:After sildenafil treatment and a subsequent non-medicated month, IIEF EF was normal in 29 of 48 (60.4%, 95%confidence interval [CI]: 45.3-74.2%) of the nightly group vs. 4 of 49 (8.2%, 95% CI: 2.3-19.6%) of the as-needed group. PSV improved by 11.2 cm/s (95% CI: 4.7-21.4; P = 0.012) in the nightly group but only by 3.4 cm/s (-5.1-14.7; P = 0.435) in the as-needed group. IIEF EF normalized in 1 of 18 (5.6%, 95% CI: 0.1-27.3%) non-medicated men and the PSV declined slightly. Six months after treatment, the IIEF EF remained normal and PSV was stabilized in most (28/29, 97%) nightly group men who had initially normalized. Conclusion: Sildenafil nightly for one year resulted in ED regression that persisted well beyond the end of treatment, so that spontaneous EF was characterized as normal on the IIEF in most men. The results from this open-label, randomized trial warrant verification under double-blind, placebo-controlled conditions.

    Introduction: Erectile dysfunction (ED) is a common occurrence and its incidence is expected to increase significantly along with the increase in various lifestyle diseases. The drug utilization for ED is very low. Also, studies describing the prescription pattern in ED are lacking. Materials and Methods: We conducted a retrospective cross-sectional observational study, including a drug utilization analysis, of 606 prescriptions as per the standard guidelines (WHO and STROBE). Results: Out of 606, 249 (41%) were from the age group of 30-39 years. Addictions were present in 388 (64%). Out of 606, 186 had urological, 154 had cardiovascular and 102 had psychological co-morbid disorders. Out of 348, 201 were prescribed Tadalafil (low dose) on a once daily basis. Out of 172, 121 were prescribed Sildenafil (high dose) on an ‘as and when required’ basis. Nutritional/ herbal supplements were prescribed in 126/606. The ratio of ‘Prescribed Daily Dose’ to ‘Defined Daily Dose’ of Tadalafil, Sildenafil, and Dapoxetine were 1.1, 1.3 and 1.5 respectively. Conclusion: Measures for de-addiction play an important role in the overall management of ED. The most common co-morbid disorders were urological, like BPH, LUTS, etc, followed by cardiovascular, psychological and diabetes. Overall, rational pharmacotherapy was observed. Tadalafil was the most commonly prescribed drug for ED. The main factor in the selection of a particular PDE5 inhibitor was its pharmacokinetics and cost. Udenafil, being the costliest, was the least prescribed. Dapoxetine was used in a significant number of individuals primarily for PE with ED. The combination of Papaverine, Chlorpromazine ± Alprostadil was used as intracavernosal injection in patients not responding to oral drugs. PMID:26393163

    Full Text Available Introduction: PDE5 inhibitors are the firstline treatment for erectile dysfunction. Although all these drugs share the same mechanism of action, each agent could have different characteristics in terms of selectivity, pharmacokinetics and tolerability profile. Materials and Methods: This manuscript illustrates a project, undertaken by the Italian Society of Urology in order to obtain a “snapshot” of the experience of Italian urologists with the use of PDE5 inhibitors in the clinical practice. This project included a survey, targeting a sample of 136 Italian urologists experienced in the treatment of ED, and the organization of a conference of experts who, based on the findings of the survey, the scientific literature and the clinical experience, would define some recommendations for the use of PDE5 inhibitors in clinical practice with a particular focus on Avanafil, the most recent drug in this class. Results: The following recommendations on the use of Avanafil were issued: 1 In patients who are candidates for the use of Avanafil, it is advisable to use the 200-mg dose from the first administration; 2 When used at the highest dose (200 mg, Avanafil shows a favourable tolerability profile with an efficacy similar to that of other agents; 3 The patient should be instructed to take Avanafil on an empty stomach, i.e., 30-45 minutes before or 2 hours after a meal; 4 The efficacy window of Avanafil is between 30 minutes and 6 hours after dosing, which qualifies this molecule as a new drug with an intermediate duration of action; 5 Avanafil at a dose of 50-100 mg/day may be a therapeutic option in chronic rehabilitation. Conclusions: Among PDE5 inhibitors, Avanafil is a new agent with an intermediate duration of action, characterized by high efficacy and good tolerability even at the highest dose (200 mg.

    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.

Besides ED is associated with others metabolic syndrome (MS components like hypertension (HT, obesity and dyslipidemia (DLP, without hyperglycemia. These observations has guided us to consider the hypothesis that ED could be installed early in patients with the MS and previously to DM2 diagnosis. Aims: To evaluate in a ED patients group: 1 metabolic and cardiovascular risk factors and MS prevalence; 2 impaired glucose tolerance prevalence. Methods: We included 77 patients with ED (group P. Control group: 17 men without ED (group C. Exclusion criteria: pharmacologic, anatomic or endocrine ED (hypogonadism or hyperprolactinemia, DM2, prior prostatic surgery or chronic illnesses. The erectile function was rated according the International Index of Erectile Function 5. Multiple metabolic and cardiovascular risk factors were evaluated: HT, DLP, obesity, smoking and sedentarism lifestyle. The MS was evaluated according the International Diabetes Federation (IDF and National Cholesterol Education Program-Third Adult Treatment Panel (NCEP-ATPIII criteria. Results: The prevalence of HT and DLP was higher in group P vs group C: 82.2 % vs 23.5 % (p=0.03 and 68.5 % vs 23.5 % (p=0.04, respectively. Twenty new cases of HT and 24 new cases of DLP were detected. Group P patients had a higher waist circumference and body mass index than group C ones: 105.3 ± 9.7 vs 98.1 ± 7.5 cm (p=0.004 and 29.8 ± 4.3 vs 26.2 ± 2.9 kg/m² (p=0.0003, respectively. The prevalence of MSIDF and MS-NCEP-ATPIII was higher in group P vs group C: 68.5 % vs 23.5 % (p=0.04 and 52.1 % vs 11.8 % (p=0.02, respectively. No differences were found in impaired glucose tolerance prevalence. Conclusion: Men with ED have a high prevalence of HT, DLP, obesity and MS. Early detection

    The concept of muscle rehabilitation after nerve injury is not a novel idea and is practiced in many branches of medicine, including urology. Bladder rehabilitation after spinal cord injury is universally practiced. The erectile dysfunction (ED) experienced after radical prostatectomy (RP) is increasingly recognized as being primarily neurogenic followed by secondary penile smooth muscle (SM) changes. There is unfortunately no standard approach to penile rehabilitation after RP because controlled prospective human studies are not available. This article reviews the epidemiology, experimental pathophysiological models, rationale for penile rehabilitation, and currently published rehabilitation strategies.

    Objective: To investigate the efficacy and safety of vacuum erection device ( VED) for erectile dysfunction (ED) after radical prostatectomy ( RP). Methods: Six cases of ED after open RP were reviewed. Three of the patients started a daily rehabilitation protocol using VED 10 min/d within 3 months after RP (group A, early intervention) , while the other 3 initiated the same protocol after 12 months (group B, late intervention). We compared the IIEF-5 scores as well as stretched penile lengths and mid-shaft circumferences before and after 3 and 6 months of VED rehabilitation. We also assessed the safety of the device and sexual satisfaction of the patients and their partners. Results: The mean IIEF-5 score of the six cases was remarkably increased at 3 and 6 months of VED rehabilitation (P<0.05) , significantly higher in group A than in B at 3 months (8. 7 ±0. 6 vs 6. 7 ±0. 6, P <0. 05) and 6 months ( 13.0 ± 1.0 vs 8. 3 ± 1.5, P<0.05). After 6 months of VED rehabilitation, there were no significant changes in stretched penile length or mid-shaft circumference in group A, both significantly decreased in group B ( P < 0.05 ) , and sexual satisfaction of the patients and their partners were 83.3% and 50% , respectively. No serious adverse events were observed except mild complaint of pe- nile skin darkening in 1 case and numb feeling during the intercourse in 2. Conclusion: Early use of VED after RP improves erectile function and helps to preserve the length and mid-shaft circumference of the penis.%目的:探讨负压勃起装置(VED)治疗前列腺癌根治术(RP)后勃起功能障碍(ED)的有效性和安全性. 方法:开放性RP术后ED患者6例,3例于术后3个月内(A组),3例于术后12个月以上(B组)分别进行VED康复治疗,比较两组在VED治疗前,治疗后3个月和6个月的IIEF-5评分的差异,治疗6个月后的阴茎长度和周径变化的差异.评价VED应用的安全性,以及患者和性伴侣的满意度. 结果:6

    Objective To study the erectile dysfunction in rats with diabetes induced by high-lipid feeding and low-dose streptozotocin (STZ) intra-abdominal injection. Methods Sixty 6-week old healthy male Wistar rats with normal e-rectile function were randomly divided into diabetic group (50 rats) and control group (10 rats, normal diet feeding). After eight weeks of high-lipid diet feeding, the diabetic model group accepted intra-abdominal injection of STZ, 35 mg/kg. At the ninth week, the tail vein blood was sampled to test the fasting glucose and lipid profile (low-intensity lipoprotein cholesterol and triglyceride) and the fasting plasma insulin. Apomorphine (APO) function test was performed to test the erectile function. Results After 8-week of high-lipid diet feeding, the weight of rats was significant increased. After injecting STZ, the blood gluscose of the diabetic group (increased to (14. 8 ± 3. 9) mmol/L), the serum insulin (decreased to (4. 3 ± 0. 7) uIU/L) and the insulin resistance index were all significantly different from those of the control group (P <0. 05). Serum triglyceride and low-intensity lipoprotein cholesterol were higher in diabetic group than those in control group (P<0. 05). There was no obivous change of the erectile function in normal group and the erection rate was 100%. In diabetic group, 1 rat died after STZ injection, 24 rats showed erection and the erectile rate (48. 9%) was significantly lower than that in normal group. Conclusion Diabetes rats induced by high-lipid feeding and low-dose STZ intra-abdominal injection have increased glucose, insulin resistance and erectile dysfunction, which can be utilized as the the model of type 2 diabetes complicated with erectile dysfunction.%目的 研究高脂喂养联合小剂量链脲佐菌素注射制备的糖尿病(diabetes mellitus,DM)大鼠的勃起功能.方法 60只6周龄,勃起功能正常的SD大鼠随机分为对照组(10只)和实验组(50只).实验组高脂喂养8周

    Aim: To assess the efficacy of sildenafil and continuous positive airway pressure (CPAP) in the treatment of concurrent erectile dysfunction (ED) with obstructive sleep apnea (OSA), and to gauge the level of treatment satisfaction in patients and their partners. Methods: Forty men were treated for 12 weeks with sildenafil 100 mg (20 men) or CPAP during nighttime sleep (20 men). Treatment efficacy was assessed by the rate of successful intercourse attempts,and satisfaction with treatment was assessed by patients' and partners' answers to question 1 of the Erectile Dysfunction Inventory of Treatment Satisfaction. Results: Under sildenafil, 128 of 249 (51.4%) intercourse attempts were successful; under CPAP, 51 of 193 (26.9%) attempts were successful (Cp < 0.001). Erectile function was improved in both groups. After sildenafil and CPAP treatment, the mean International Index for Erectile Function domain scores were 14.3 and 10.8, respectively (Bp = 0.025), compared to 7.8 and 7 at baseline, respectively. CPAP and sildenafil were well tolerated. Sporadic episodes of nasal dryness under CPAP and transient headache and flushing under sildenafil were not significant. Fifty percent of patients treated with sildenafil and 25% with CPAP were satisfied with the treatment, and their partners were equally satisfied. The satisfaction scores for both patients and partners under sildenafil were superior to those under CPAP (Cp < 0.002). Conclusion: Both sildenafil 100 mg and CPAP, used separately, had positive therapeutic impact but sildenafil was superior. Patients and their partners were more satisfied with sildenafil for the treatment of ED. However, because of the high proportion of dissatisfied men and partners, new therapeutic agents or a combination of the two methods must be studied further.

    Robotic surgery is becoming more and more commonplace. At the same time, so are complications, especially related to erectile function. The population being diagnosed with cancer is younger, with more aggressive cancers and higher expectations for good erectile function postoperatively. We conduct a retrospective analysis of literature over 20 years for Embase and Medline. Search terms used include (Robotic) AND (prostatectomy) AND (erectile function). There are a variety of multifactorial causes, resulting in worsening ED post-robotic radical prostatectomy; however, there are a number of treatments that can support this. There is much we can do to help prevent patients getting postoperative erectile dysfunction post-radical surgery. However, part of this is management of realistic patient expectations. PMID:27272758

    Purpose Recently, reports in the mass media have implicated that bicycle riding increases the risk of erectile dysfunction and prostatic diseases. So, we evaluate the impact of bicycle riding on erectile function and lower urinary tract symptoms (LUTS) in healthy general men. Methods From 26 June 2010 to 20 July 2010, we investigate degree of LUTS (voiding and storage symptoms), using International Continence Society-male Questionnaire (ICS-mQ) and erectile function using International Index of Erectile Function-5 Questionnaire (IIEF-5) in 5 work places (personnel of public office, hospital, university, etc.) of which bicycle riding club members were doing active club activities. Respondents, who participated in club activities for 6 months and longer, were classified as the bicycle club (142 men; age, 44.02±8.56). Ones who do not ride bicycles were classified as the control group (83 men; age, 42.13±7.85). People who were having the history of urological and other chronic diseases (diabetes, vascular disease, heart disease, etc) were excluded from both groups. Results Bicycle club is not significantly associated with increased prevalence of LUTS (bicycle club, 2.1 to 57.7% control, 4.8 to 73.5%) and erectile dysfunction (bicycle club, 46.1% control, 55.4%). The total mean score (storage/voiding/erectile function) of bicycle club (13.93±1.95/11.14±3.49/20.46±5.30) were not significantly different from control (14.35±2.49/11.52±3.38/20.40±4.07) (P=0.190 to 0.968). Conclusions These results suggested that bicycle riding as exercise or hobby has no negative effect on LUTS and erectile function in healthy general men, although this research data were limited to the questionnaire analysis.

    1985-01-01

    The purpose of this study was to develop and validate the Sexual Self-Efficacy Scale (SSES-E) for erectile disorder. The subjects consisted of 15 heterosexual couples with nonproblematic sexual functioning (normal group) and a sexually dysfunctional sample consisting of nine heterosexual couples and eight heterosexual single males (dysfunctional group). Most of the males in the dysfunctional sample were diagnosed as suffering from erectile disorder. Reliability of the SSES-E, based on test-retest and split-half correlations and on item analyses, appears to be reasonable. Validity, measured in three different ways, is also acceptably high. Suggestions for the use of this instrument in clinical practice and for future research are made.

    Objective To investigate the feasibility of restoring erectile function by repairing abla-ted cavernous nerve with neural stem cell grafts. Methods Forty-two male Sprague-Dawley rats (3-4 months old, weighing 300-400 g) were randomly divided into three groups: sham-operated controls (n = 14 ) subject to pelvic exploration without transection of the cavernous nerve; nerve ablation group (n = 14) having a 3 nun segment of cavernous nerve excised bilaterally; graft group (n = 14) having a 3 mm segment of cavernous nerve excised bilaterally, followed by immediate neural stem cell grafting. Two and 4 months postoperatively the rats of each group were electrostimulated to the cavernousal nerves to determine potency. Corpora cavernosa were harvested and nNOS-positive nerve fibers were examined by using immunohisto-chemistry. Results At the 2nd month postoperatively, electrical stimulation produced no erections in the nerve ablation or the graft group and 100 % erections in the sham-operated group. There was no significant difference in the nNOS-positive nerve fibers between the nerve ablation group and the graft group. At the 4th month postoperatively, 57. 14% of the grafted nerves produced erections upon electrical stimulation, significantly different from that in the nerve ablation group (7. 19% ). The nNOS-positive nerve fibers in the graft group (86. 0 ± 13.4) significantly differed from those in the nerve ablation group (26. 5±4. 3), and approximated the level of the sham-operated group (95.1 ± 7.7). Conclusion Neural stem cell graft-ing can be an effective method in restoring potency after injury.%目的 观察神经干细胞移植修复损伤的海绵体神经从而恢复勃起功能的可行性.方法 42只雄性SD大鼠(3~4个月龄和体质量300~400 g)随机分为假手术组、神经干细胞移植组和神经损伤组,每组14只.2、4个月后,海绵体神经电刺激检测大鼠阴茎勃起功能,免疫组织化学法检测海绵体内一氧化氮

    Aim: To investigate the effect of substituting β-blockers with nebivolol on the erectile function of patients suffering from essential hypertension. Methods: Forty-four young and middle-aged men (31-65 years) with essential hypertension visited our outpatient clinic and took β-blocker treatment (atenolol, metoprolol or bisoprolol) for more than 6months. All the patients completed a questionnaire regarding erectile function (International Index for Erectile Function).Patients were then switched to an equipotent dose of nebivolol for 3 months and, at the end of this time period, filled out the same questionnaire. Results: Twenty-nine out of the 44 (65.9%) patients who took β-blockers (atenolol,metoprolol or bisoprolol) had exhibited erectile dysfunction (ED). Their systolic and diastolic blood pressure did not change significantly with the treatment switch. In 20 out of these 29 (69%) patients, a significant improvement in the erectile function score was exhibited after 3 months of nebivolol administration, and in 11 of these 20 patients, erectile function was normalized. Conclusion: Nebivolol seems to have a beneficial effect on ED (possibly due to increased nitric oxide availability); however, further prospective, randomized, placebo-controlled studies are needed to confirm the beneficial effects of nebivolol.

    The seriousness of metabolic syndrome is not due to the disease itself but its promotion of other diseases,such as erectile dysfunction and cardiovascular and cerebrovascular diseases.We investigated the effects of Korean red ginseng (KRG,Panax ginseng) extract on erectile function in a rat model of metabolic syndrome.We divided the rats into three groups:control,metabolic syndrome+normal saline (N/S) and metabolic syndrome+ KRG.To determine the occurrence of metabolic syndrome in all groups,body weight and various biochemical parameters (e.g.,blood glucose,insulin,cholesterol) were measured,and the intra-abdominal glucose tolerance test was performed.To investigate penile erection,the peak intracavernosal pressure (ICP),mean arterial pressure (MAP) and Masson's trichrome stain were evaluated.Erectile function was also investigated by measuring the cyclic guanosine monophosphate (cGMP)levels of the corpus cavernosum.We found that the various biochemical parameters and body weight were similar in the metabolic syndrome+KRG group and the control group,although the values were slightly higher.The peak ICP/MAP ratio of the metabolic syndrome+ N/S group was markedly decreased compared to the other groups.The cGMP level of the corpus cavemosum in the metabolic syndrome+N/S group was significantly lower than that of the other groups.As demonstrated in this model of metabolic syndrome with erectile dysfunction,KRG may improve erectile function.

  12. Analysis of erectile responses to H2S donors in the anesthetized rat.

    Hydrogen sulfide (H2S) is a biologically active endogenous gasotransmitter formed in penile tissue that has been shown to relax isolated cavernosal smooth muscle. In the present study, erectile responses to the H2S donors sodium sulfide (Na2S) and sodium hydrosulfide (NaHS) were investigated in the anesthetized rat. Intracavernosal injections of Na2S in doses of 0.03-1 mg/kg increased intracavernosal pressure and transiently decreased mean arterial pressure in a dose-dependent manner. Blood pressure responses to Na2S were rapid in onset and short in duration. Responses to Na2S and NaHS were similar at doses up to 0.3 mg/kg, after which a plateau in the erectile response to NaHS was reached. Increases in intracavernosal pressure in response to Na2S were attenuated by tetraethylammonium (K(+) channel inhibitor) and iberiotoxin (large-conductance Ca(2+)-activated K(+) channel inhibitor), whereas glybenclamide [ATP-sensitive K(+) (KATP) channel inhibitor] and inhibitors of nitric oxide (NO) synthase, cyclooxygenase, and cytochrome P-450 epoxygenase had no effect. These data indicate that erectile responses to Na2S are mediated by a tetraethylammonium- and iberiotoxin-sensitive mechanism and that KATP channels, NO, or arachidonic acid metabolites are not involved. Na2S did not alter erectile responses to sodium nitroprusside (NO donor) or cavernosal nerve stimulation, indicating that neither NO nor cGMP metabolism are altered. Thus, Na2S has erectile activity mediated by large-conductance Ca(2+)-activated K(+) channels. It is suggested that strategies that increase H2S formation in penile tissue may be useful in the treatment of erectile dysfunction when NO bioavailability, KATP channel function, or poor responses to PGE1 are present.

    Full Text Available Trichotillomania is a chronic psychiatric disorder characterized by pulling out one's own hair, which results in an obvious loss of hair. Hair pulling was first described in Henri Allopeau in 1889. The term "trichotillomania" comes from the Greek words "thrix" - hair, "tillein" - to pull and "Mania" madness or frenzy. 30 year old man presented with complaints of hairpulling behavior and associated erectile dysfunction. His hairpulling behavior improved on treating his sexual dysfunction.

    Erectile impotence is a common complaint in alcoholics, but its mechanism is unknown. We have studied nocturnal penile erection in 13 alcoholics who complained of impotence. Seven had normal erections and their impotence was therefore psychogenic. Six were found to have diminished or absent nocturnal erections. Plasma concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were elevated in this latter group, with the exception of one patient who had only raised FSH. They also had more evidence of neurological damage than the other seven alcoholics, and two had evidence of damage to the parasympathetic nervous system. Investigation of erection during sleep in alcoholic patients with impotence may be useful in differentiating clinically between patients with psychogenic causes and patients with organic causes of impotence.

  17. Meta-analysis of rates of erectile function after treatment of localized prostate carcinoma

    International Nuclear Information System (INIS)

    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

    There is an unmet need for treatment of erectile dysfunction resulting from radical prostatectomy and cavernous nerve (CN) injury. Given the neuroprotective properties of docosahexaenoic acid (DHA), we investigated its effect on penile functional and structural recovery in a rat model of bilateral cavernous nerve injury. Rats were subject to CN injury and received intraperitoneal administration of either vehicle or a DHA nanoemulsion (nano-DHA) at 10, 50, or 250 μg/kg. Functional testing and histological analyses were performed at 28 days post-injury. The maximum intracavernosal pressure (ICP) and other measures of erectile function were significantly higher in the nano-DHA groups than in the vehicle group (p erectile function after bilateral CN injury in rats by neuroprotection and other anti-fibrotic and anti-apoptotic mechanisms.

  5. Sexual dysfunctions after prostate cancer radiation therapy; Dysfonctions sexuelles apres irradiation pour cancer de la prostate

    Energy Technology Data Exchange (ETDEWEB)

    Droupy, S. [Service d' urologie-andrologie, CHU Caremeau, 30 - Nimes (France)

    2010-10-15

    Sexual dysfunctions are a quality of life main concern following prostate cancer treatment. After both radiotherapy and brachytherapy, sexual function declines progressively, the onset of occurrence of erectile dysfunction being 12-18 months after both treatments. The pathophysiological pathways by which radiotherapy and brachytherapy cause erectile dysfunction are multi-factorial, as patient co-morbidities, arterial damage, exposure of neurovascular bundle to high levels of radiation, and radiation dose received by the corpora cavernosa at the crurae of the penis may be important in the aetiology of erectile dysfunction. Diagnosis and treatment of postradiation sexual dysfunctions must integrate pre-therapeutic evaluation and information to provide to the patient and his partner a multidisciplinary sexual medicine management.

    Full Text Available Abstract Background The molecular mechanisms responsible for the survival and preservation of function for adult parasympathetic ganglion neurons following injury remain incompletely understood. However, advances in the neurobiology of growth factors, neural development, and prevention of cell death have led to a surge of clinical interest for protective and regenerative neuromodulatory strategies, as surgical therapies for prostate, bladder, and colorectal cancers often result in neuronal axotomy and debilitating loss of sexual function or continence. In vitro studies have identified neurturin, a glial cell line-derived neurotrophic factor, as a neuromodulator for pelvic cholinergic neurons. We present the first in vivo report of the effects of neurturin upon the recovery of erectile function following bilateral cavernous nerve crush injury in the rat. Methods In these experiments, groups (n = 8 each consisted of uninjured controls and animals treated with injection of albumin (blinded crush control group, extended release neurotrophin-4 or neurturin to the site of cavernous nerve crush injury (100 μg per animal. After 5 weeks, recovery of erectile function (treatment effect was assessed by cavernous nerve electrostimulation and peak aortic pressures were measured. Investigators were unblinded to specific treatments after statistical analyses were completed. Results Erectile dysfunction was not observed in the sham group (mean maximal intracavernous pressure [ICP] increase of 117.5 ± 7.3 cmH2O, whereas nerve injury and albumin treatment (control produced a significant reduction in ICP elevation of 40.0 ± 6.3 cmH2O. Neurturin facilitated the preservation of erectile function, with an ICP increase of 55% at 62.0 ± 9.2 cmH2O (p Conclusion Treatment with neurturin at the site of cavernous nerve crush injury facilitates recovery of erectile function. Results support further investigation of neurturin as a neuroprotective and/or neuroregenerative

    Full Text Available Erectile dysfunction (ED is a major health problem worldwide and affects approximately 75% of diabetic patients, likely due to severely damaged cavernous body. While screening for cytokines produced by adipose tissue-derived stem cells, we detected neuromedin B (NMB. To explore a potential treatment option for ED, we examined whether NMB was capable of restoring erectile function. We also examined the potential mechanism by which NMB could restore erectile function. Male Wistar rats were injected with streptozotocin (STZ to induce diabetes. An adenovirus expressing NMB (AdNMB was injected into the penis 6 weeks after STZ administration. Four weeks after the injection of AdNMB, erectile function, penile histology, and protein expression were analyzed. As assessed by the measurement of intracavernous pressure, AdNMB injection significantly restored erectile function compared with the injection of an adenovirus expressing green fluorescent protein. This restoration was associated with conservation of the cavernous body structure and neural nitric oxide synthase (nNOS-expressing nerves, together with recovery of α-smooth muscle actin, vascular endothelial-cadherin, and nNOS expression. Furthermore, NMB significantly stimulated the survival of SH-SY5Y cells derived from human neuroblastoma tissue with characteristics similar to neurons. Collectively, these results suggested that NMB restored erectile function via protection of the cavernous body from injury and stimulation of the survival of the associated nerves. NMB may be useful to treat ED patients with a severely damaged cavernous body.

    The use of natural substances for the treatment of diseases or injuries is an ancient practice of many cultures. According to folklore, natural aphrodisiacs may help to raise libido and increase desire. The supposed aphrodisiacs mainly include a plethora of preparations of plants, among other substances. However, the real boundary between myth and reality has not been established yet in most cases and such boundaries must be drawn by scientific methods. A growing interest of the scientific community has been focused on animal venoms, especially those from arthropods, i.e. spiders and scorpions, which cause priapism, a prolonged and painful erection. This review highlights the studies that have been performed with venoms and toxins from arthropods known to cause priapism, among other toxic symptoms, pointing out some pharmacological approaches for better understanding this effect. To date, the venom of some spiders, mainly Phoneutria nigriventer, and scorpions, such as the yellow South American scorpion Tityus serrulatus, among others, have been known to cause priapism. Since erectile dysfunction (ED) is a growing health problem in the world, more common in patients with vascular diseases as diabetes and hypertension, the use of animal venoms and toxins as pharmacological tools could not only shed light to the mechanisms involved in erectile function, but also represent a possible model for new drugs to treat ED. Unfortunately, attempts to correlate the structure of those priapism-related toxins were unfruitful. Such difficulties lie firstly on the poor data concerning purified priapism-related toxins, instead of whole venoms and/or semi-purified fractions, and secondly, on the scarce available primary sequences and structural data, mainly from spider toxins. It has been shown that all these toxins modify the sodium (Na(+)) channel activity, mostly slowing down its inactivation current. Improving the knowledge on the tertiary structure of these toxins could provide

    Aim: To evaluate the effects of metabolic profiles on lower urinary tract symptoms (LUTS) in men with erectile dysfunction (ED). Methods: A total of 75 impotent men aged 25-75 years old (mean 58.1 years) were included in the study on a prospective basis. Patients were evaluated with a complete history, physical examination, anthropometry and metabolic profiles. LUTS were assessed using the International Prostate Symptom Score (IPSS). Results:Overall, there was no correlation between the IPSS and continuous parameters. However, when continuous variables were categorized, some parameters were significantly associated with LUTS. Patients with triglyceride level of 150 mg/Dl or higher had more severe symptoms than those with tiglyceride levels less than 150 mg/Dl (19.4 ± 2.4vs. 14.3 ± 1.1, P = 0.033). When 40 mg/Dl was chosen as the high-density lipoprotein (HDL)-cholesterol cut-off level, the IPSS was significantly different between the two groups divided by 40 mg/Dl (19.4 ± 2.6 for HDL-cholesterol < 40 mg/Dl vs. 14.4 ± 1.0 for HDL-cholesterol ≥ 40 mg/Dl, P = 0.042). The area under the receiver operating characteristic curve (AUROCC) of triglyceride was 65.7% (95% confidence interval [CI], 52.6%-82.3%; P = 0.034)for severe LUTS. However, the AUROCC for 'HDL-cholesterol' was not significant (area, 65.4%; 95% CI, 48.2%-82.7%;P = 0.062). No other factors were determined to be significant in this regard. Conclusion: The results of the present study indicate that some metabolic profiles might influence LUTS in men with ED.

    Full Text Available Maria Ida Maiorino,1 Giuseppe Bellastella,1 Katherine Esposito2 1Department of Medical, Surgical, Neurological, Metabolic and Geriatric Sciences, Second University of Naples, Naples, Italy; 2Department of Clinical and Experimental Medicine, Second University of Naples, Naples, Italy Abstract: Diabetes mellitus is one of the most common chronic diseases in nearly all countries. It has been associated with sexual dysfunction, both in males and in females. Diabetes is an established risk factor for sexual dysfunction in men, as a threefold increased risk of erectile dysfunction was documented in diabetic men, as compared with nondiabetic men. Among women, evidence regarding the association between diabetes and sexual dysfunction are less conclusive, although most studies have reported a higher prevalence of female sexual dysfunction in diabetic women as compared with nondiabetic women. Female sexual function appears to be more related to social and psychological components than to the physiological consequence of diabetes. Hyperglycemia, which is a main determinant of vascular and microvascular diabetic complications, may participate in the pathogenetic mechanisms of sexual dysfunction in diabetes. Moreover, diabetic people may present several clinical conditions, including hypertension, overweight and obesity, metabolic syndrome, cigarette smoking, and atherogenic dyslipidemia, which are themselves risk factors for sexual dysfunction, both in men and in women. The adoption of healthy lifestyles may reduce insulin resistance, endothelial dysfunction, and oxidative stress – all of which are desirable achievements in diabetic patients. Improved well-being may further contribute to reduce and prevent sexual dysfunction in both sexes.

    Objective To investigate the pathological changes of tunica albuginea in erectile dysfunction (ED), the role of tunics albuginea in penis erection, and the therapeutic effect of phosphodiesterase-5 inhibitor (PDESI) on ED. Methods Thirty 8-week-old male Sprague-Dawley rats were randomly divided into 3 equal groups:(1) control group fed with normal diet for 16 weeks, (2) high-fat group fed with the diet containing 2% cholesterol and 10% pork fat, and(3) Tadalafil group fed with high-fat diet for 16 weeks and undergoing gastric perfusion of Tadalafil 2 mg/kg daily since the 13th week for 4 weeks. Sixteen weeks later, intracavernous pressure and mean arterial pressure were measured, and the ratio of maximal intracavernous pressure to mean arterial pressure (ICP/MAP) was calculated blood samples were collected. Blood samples were collected from the abdominal aorta to undergo lipid profile test. Then penis was cut. Victoria blue/ponceau red staining and color image analysis were used to observe the content of elastic fibers in the tunics albuginea. Results The ICP/MAP of the high-fat group was 0. 49 ± 0. 05, significantly lower than that of the control group (0. 82±0. 06, P <0. 01 ). The ICP/MAP of the Tadalafil group was 0. 60 ± 0. 02, significantly higher than that of the high-fat group ( P < 0. 05 ). The content of elastic fibers in tunica albuginea of the high-fat group was 468 ± 152, significantly lower than that of the the control group (3292 ± 1123, P < 0. 01 ). The content of elastic fibers in tunica albuginea of the Tedalafil group was 2062 ± 560, significantly higher than that of the high-fat group (P < 0.05 ).

    Aim: To investigate the effect of icariin on erectile function and the expression of nitric oxide synthase (NOS)isoforms in castrated rats. Methods: Thirty-two adult male Wistar rats were randomly divided into one sham-operated group (A) and three castrated groups (B, C and D). One week after surgery, rats were treated with normal week after treatment, the erectile function of the rats was assessed by measuring intracavernosal pressure (ICP)during electrostimulation of the cavernosal nerve. The serum testosterone (ST) levels, the percent of smooth muscle (PSM) in trabecular tissue, and the expression of mRNA and proteins of neuronal nitric oxide synthase (nNOS),inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase (eNOS) and phosphodiesterase V (PDE5) in corpus cavernosum (CC) were also evaluated. Results: ICP, PSM, ST and the expression of nNOS, iNOS, eNOS and PDE5 were significantly decreased in group B compared with those in group A (P < 0.01). However, ICP, PSM and the expression of nNOS and iNOS were increased in groups C and D compared with those in group B (P < 0.05).Changes in ST and the expression of eNOS and PDE5 were not significant (P > 0.05) in groups C and D compared with those in group B. Conclusion: Oral treatment with icariin (> 98.6 % purity) for 4 weeks potentially improves erectile function. This effect is correlated with an increase in PSM and the expression of certain NOS in the CC of castrated rats. These results suggest that icariin may have a therapeutic effect on erectile dysfunction.

    Full Text Available Purpose. To determine the mechanisms predisposing penile fracture as well as the rate of long-term penile deformity and erectile and voiding functions. Methods. All fractures were repaired on an emergency basis via subcoronal incision and absorbable suture with simultaneous repair of eventual urethral lesion. Patients’ status before fracture and voiding and erectile functions at long term were assessed by periodic follow-up and phone call. Detailed history included cause, symptoms, and single-question self-report of erectile and voiding functions. Results. Among the 44 suspicious cases, 42 (95.4% were confirmed, mean age was 34.5 years (range: 18–60, mean follow-up 59.3 months (range 9–155. Half presented the classical triad of audible crack, detumescence, and pain. Heterosexual intercourse was the most common cause (28 patients, 66.7%, followed by penile manipulation (6 patients, 14.3%, and homosexual intercourse (4 patients, 9.5%. “Woman on top” was the most common heterosexual position (n=14, 50%, followed by “doggy style” (n=8, 28.6%. Four patients (9.5% maintained the cause unclear. Six (14.3% patients had urethral injury and two (4.8% had erectile dysfunction, treated by penile prosthesis and PDE-5i. No patient showed urethral fistula, voiding deterioration, penile nodule/curve or pain. Conclusions. “Woman on top” was the potentially riskiest sexual position (50%. Immediate surgical treatment warrants long-term very low morbidity.

    Aim: To explore the barriers faced by general practitioners (GPs) in the management of patients with erectile dysfunction (ED). Methods: This was a qualitative analysis of focus group discussions and in-depth interviews involving 28 Malaysian GPs. Results: GPs' perception of ED being not a serious condition was a major determinant of their prescribing practice. Doctor's age (younger), gender (female), short consultation time and lack of experience were cited as barriers. The GPs' prescribing habits were heavily influenced by the feedback from the first few patients under treatment, the uncertainty of etiology of ED without proper assessment and the profit margin with bulk purchase. Other barriers include Patients' coexisting medical conditions, older age, lower socio-economic status, unrealistic expectations and inappropriate use of the anti-impoteneet drugs. Cardiovascular side effects and cost were two most important drug barriers. Conclusion: The factors influencing the management of ED among the general practitioners were multiple and complex. An adequate understanding of how these factors (doctors, patientsand drugs) interact can assist in the formulation and implementation of strategies that encourage GPs to identify and manage ED patients.

    We aimed to evaluate the effect of acetylsalicylic acid (ASA) treatment on diabetes-induced erectile dysfunction. Adult male Sprague-Dawley rats were divided into four groups as follows: (i) control (C), (ii) diabetic (D), (iii) ASA-treated control (C+ASA) and (iv) ASA-treated diabetic (D+ASA) groups. In groups 2 and 4, diabetes was induced by injection of 35 mg kg(-1) streptozotocin. ASA (100 mg kg(-1) day(-1) , orally) was administrated to rats in groups 3 and 4 for 8 weeks. Both intracavernosal pressure (ICP) and mean arterial blood pressure (MAP) were measured in in vivo studies. In organ bath, the relaxation responses to acetylcholine (ACh), electrical field stimulation (EFS) and sodium nitroprusside were tested in corpus cavernosum (CC) strips. The mRNA expression for neuronal nitric oxide synthase (nNOS) was calculated using reverse transcription polymerase chain reaction technique. In in vivo experiments, diabetic rats displayed reduced ICP/MAP values, which were normalised with ASA treatment. The relaxant response to high-dose ACh and EFS at low frequencies (1-8 Hz) in CC strips from the D+ASA group were significantly higher when compared to the D group. Treatment with ASA normalised the raised mRNA expressions of nNOS in diabetic penile tissues. ASA may be involved in mRNA of protein synthesis of NO released from nonadrenergic and noncholinergic cavernosal nerve in diabetes.

    Penile erection is a neurovascular phenomenon, and erectile dysfunction (ED) is caused mainly by vascular risk factors or diseases, neurologic abnormalities, and hormonal disturbances. Men with diabetic ED often have severe endothelial dysfunction and peripheral nerve damage, which result in poor response to oral phosphodiesterase-5 inhibitors. Nerve injury-induced protein 1 (Ninjurin 1, Ninj1) is known to be involved in neuroinflammatory processes and to be related to vascular regression during the embryonic period. Here, we demonstrate in streptozotocin-induced diabetic mice that inhibition of the Ninj1 pathway by administering Ninj1-neutralizing antibody (Ninj1-Ab) or by using Ninj1-knockout mice successfully restored erectile function through enhanced penile angiogenesis and neural regeneration. Angiopoietin-1 (Ang1) expression was down-regulated and angiopoietin-2 expression was up-regulated in the diabetic penis compared with that in controls, and these changes were reversed by treatment with Ninj1-Ab. Ninj1 blockade-mediated penile angiogenesis and neural regeneration as well as recovery of erectile function were abolished by inhibition of Ang1-Tie2 (tyrosine kinase with Ig and epidermal growth factor homology domain-2) signaling with soluble Tie2 antibody or Ang1 siRNA. The present results suggest that inhibition of the Ninj1 pathway will be a novel therapeutic strategy for treating ED. PMID:24979788

  2. Psychiatric disorders and sexual dysfunction.

    2015-01-01

    Sexual problems are highly prevalent among patients with psychiatric disorders. They may be caused by the psychopathology of the psychiatric disorder but also by its pharmacotherapy. Both positive symptoms (e.g., psychosis, hallucinations) as well as negative symptoms (e.g., anhedonia) of schizophrenia may negatively interfere with interpersonal and sexual relationships. Atypical antipsychotics have fewer sexual side-effects than the classic antipsychotics. Mood disorders may affect libido, sexual arousal, orgasm, and erectile function. With the exception of bupropion, agomelatine, mirtazapine, vortioxetine, amineptine, and moclobemide, all antidepressants cause sexual side-effects. Selective serotonin reuptake inhibitors (SSRIs) may particularly delay ejaculation and female orgasm, but also can cause decreased libido and erectile difficulties. SSRI-induced sexual side-effects are dose-dependent and reversible. Very rarely, their sexual side-effects persist after SSRI discontinuation. This is often preceded by genital anesthesia. Some personality characteristics are a risk factor for sexual dysfunction. Also patients with eating disorders may suffer from sexual difficulties. So far, research into psychotropic-induced sexual side-effects suffers from substantial methodologic limitations. Patients tend not to talk with their clinician about their sexual life. Psychiatrists and other doctors need to take the initiative to talk about the patient's sexual life in order to become informed about potential medication-induced sexual difficulties. PMID:26003261

    There is an unmet need for treatment of erectile dysfunction resulting from radical prostatectomy and cavernous nerve (CN) injury. Given the neuroprotective properties of docosahexaenoic acid (DHA), we investigated its effect on penile functional and structural recovery in a rat model of bilateral cavernous nerve injury. Rats were subject to CN injury and received intraperitoneal administration of either vehicle or a DHA nanoemulsion (nano-DHA) at 10, 50, or 250 μg/kg. Functional testing and histological analyses were performed at 28 days post-injury. The maximum intracavernosal pressure (ICP) and other measures of erectile function were significantly higher in the nano-DHA groups than in the vehicle group (p nitric oxide synthase (nNOS)/β-III tubulin, numbers of axon and smooth muscle cell content were significantly higher in the 50 μg/kg nano-DHA group than in the vehicle group (p < 0.05). A qualitative increase in the smooth muscle cells/collagen ratio and decrease in apoptosis was observed in the nano-DHA groups relative to the vehicle group: however, these differences were not statistically significant. Our data demonstrate that nano-DHA, particularly the 50 μg/kg regimen, improves erectile function after bilateral CN injury in rats by neuroprotection and other anti-fibrotic and anti-apoptotic mechanisms.

    Chronic prostatitis/ chronic pelvic pain syndrome (CP/CPPS), or NIH category III prostatitis, is a clinical syndrome characterized by genital/ pelvic pain and lower urinary tract symptoms in the absence of urinary tract infection. CPPS is the most common prostatic disease in men younger than 50 years of age and the third most common in men older than 50 years of age. CP/CPPS is a complex entity with unclear etiology. Many articles reported that the high percentage of patients with CP/CPPS had sexual dysfunction. The most common symptoms of sexual dysfunction in chronic prostatitis patients are erectile dysfunction (ED), painful ejaculation and premature ejaculation. So we will discuss about ED and ejaculation problems in CP/CPPS patients.

  5. Erectile function following brachytherapy, external beam radiotherapy, or radical prostatectomy in prostate cancer patients

    International Nuclear Information System (INIS)

    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.)

    Men with diabetes have an increased risk for erectile dysfunction (ED) than those without diabetes. The diabetes control and complications trial clearly showed that better long-term control of blood glucose in diabetes type 1 is associated with decreased frequency and delayed the onset of microvascular complications. The aim of this study is to explore the role of glycemic control, and its correlation to sexual function in patients with diabetes type 2. One hundred patients were selected for the study according to the following criteria: all the cases were presenting with diabetes type 2 as a single risk factor for ED, age being between 35 and 50 years and free of liver and kidney failure, and blood dyscrasis. The selected patients were evaluated for sexual function by asking the patients to complete the abridged form of the International Index of Erectile Function (IIEF). The evaluation of glycemic control was based on the measurement of hemoglobin A(1c) (HbA(1c)) values. Our results showed that the level of HbA(1c) is significantly higher with declining degrees of potency (P-value=0.003). Also, there is an association between potency degree and glycemic control (P=0.002). We conclude that glycemic control is independently and inversely associated with ED in men with diabetes type 2.

    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.

    We explored the balance of genetic and environmental factors on sexual dysfunctions during first intercourse experience in young men. Gender role conflict theory predicts that young males should show high levels of such dysfunctions coupled with mixed affective reactions. Three thousand one hundred eighty six male twins and their siblings (M = 26.17 years, SD = 4.77) completed items on erectile dysfunction (ED), premature ejaculation (PE), contextual factors, and affective reactions during first intercourse, as well as parental attitudes towards nudity and sexuality. Twin modeling revealed a significant genetic effects for PE, but not for ED. Experiences of sexual dysfunction and both negative and positive affects during first intercourse were common among the participants. More positive parental attitudes were associated with less dysfunction and more positive affect during first intercourse. Having the first sexual intercourse with an unknown partner and while strongly intoxicated were, together with group pressure and reluctance to engage in intercourse, related to more negative and less positive affects. Erectile dysfunction during the first intercourse was related to more negative and less positive affects. PMID:19266379

    This study sought to investigate the clinical efficacy and safety of combined oral therapy with sildenafil and doxazosin GITS compared to sildenafil monotherapy in treating Chinese patients with erectile dysfunction (ED) and lower urinary tract symptoms secondary to benign prostatic hyperpiasia (BPH/LUTS). The trial was conducted in hospitals in Beijing, Shanghai, Changsha, Wuhan and Guangzhou, five major cities in China. A total of 250 patients diagnosed with ED and BPH/LUTS aged 50-75 years, and who had International Index of Erection Function-5 (lIEF-5) scores ≤ 21 and international Prostate Symptom Score (IPSS) ≥ 10 points, were enrolled and randomly divided into Group A (168 cases; doxazosin GITS 4 mg once daily plus sildenafil 25-100 mg on demand) and Group B (82 cases; sildenafil 25-100 mg on demand). Efficacies were evaluated by lIEF-5 and IPSS scores and a quality of life (QoL) questionnaire, and adverse effects were evaluated during the treatment period. There were no statistically significant differences in mean age, and lIEF-5, IPSS and QoL scores pre-treatment between the two groups. After treatment, lIEF-5, IPSS and QoL scores were significantly improved in Group A, while only lIEF-5 scores were significantly improved in Group B compared with pre-treatment. There were no significant differences in side effects between the two groups. The results indicated that combined therapy with sildenafil and doxazosin GITS for the treatment of ED and BPH/LUTS is safe and effective compared to sildenafil monotherapy.

  15. Overexpression of arginase in the aged mouse penis impairs erectile function and decreases eNOS activity: influence of in vivo gene therapy of anti-arginase.

    Since both increased nitric oxide (NO) synthase (NOS) abundance and diminished NO signaling have been reported in the aging penis, the role of NO in the adaptations of aging remains controversial. Here we tested the hypothesis that arginase, an enzyme that competes with NOS for the substrate l-arginine, contributes to erectile dysfunction with advanced age in the B6/129 mouse strain. Arginase protein abundance, mRNA expression, and enzyme activity were elevated in aged compared with young penile endothelial cells. In addition, endothelial NOS (NOS3) protein abundance was greater in aged versus young penile endothelial cells, whereas NOS activity and cGMP levels were reduced. Calcium-dependent l-arginine-to-l-citrulline conversion and cGMP formation increased significantly in aged mouse penes in the presence of the arginase inhibitor 2(S)-amino-6-boronohexanoic acid (ABH). However, there was no effect on l-arginine-to-l-citrulline conversion or cGMP accumulation in the endothelium from young mouse penes. To assess the functional role of arginase in the inhibition of NOS pathway responsiveness in the penis, we evaluated the effects of ABH and an adeno-associated virus encoding an antisense sequence to arginase I (AAVanti-arginase) on erectile function in vivo. ABH and AAVanti-arginase enhanced endothelium-dependent erectile responses in the aged mice without altering endothelium-independent responses. Paralleling our in vitro observations, ABH or AAVanti-arginase did not affect vascular responses in the young mice. Inhibition of the arginase pathway improves endothelial function in the aging penile circulation, suggesting that the arginase pathway may be exploited to improve erectile dysfunction associated with aging.

    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.

    Full Text Available OBJECTIVE: To investigate whether methadone maintenance treatment (MMT is correlated with sexual dysfunction in heroin-dependent men and to determine the prevalence and risk factors of sexual dysfunction among men on MMT. METHODS: The study included a retrospective survey and a cross-sectional survey which contained interviews of 293 men who are currently engaged in MMT. The results of the two surveys were compared. For a subset of 43 participants, radioimmunoassay was additionally conducted using retrospective and prospective blood samples to test the levels of plasma testosterone and luteinizing hormone. Other study evaluations were the International Index of Erectile Function (IIEF-15, and Self-rating Depression Scale. RESULTS: Sexual dysfunction in all five IIEF-15 domains (erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction was strongly associated with long-term use of heroin. A decrease in the severity of sexual dysfunction was associated with MMT initiation. Erectile dysfunction, lack of sexual desire, inability to orgasm, and lack of intercourse satisfaction were significantly correlated with increasing age of the participants. Methadone dose and duration of methadone treatment were not found to be associated with sexual dysfunction. The level of plasma testosterone significantly declined during methadone treatment, but results from multivariate analysis indicated low levels of testosterone were not the main cause of sexual dysfunction. No correlation between reported depression status and sexual function was found. CONCLUSIONS: While high levels of sexual dysfunction were reported by heroin-dependent men in our study before and after MMT initiation, MMT appears to be correlated with improved sexual function in the population of the study.

    Apomorphine HCl (Apo) (0.5 mg sc), but not placebo, induced an erectile response (monitored with a mercury strain gauge) lasting 40 min in an impotent hyperprolactinemic patient. Serial blood sampling modified the 40 min erectile response. Prompt detumescence followed by complete or partial restoration of tumescence occurred each time blood was drawn. This observation points to the sensitivity of the Apo-erectile response to experimental procedures subjectively perceived as anxiogenic.

    Normal sexual and reproductive functions depend largely on neurological mechanisms. Neurological defects in men can cause infertility through erectile dysfunction, ejaculatory dysfunction and semen abnormalities. Among the major conditions contributing to these symptoms are pelvic and retroperitoneal surgery, diabetes, congenital spinal abnormalities, multiple sclerosis and spinal cord injury. Erectile dysfunction can be managed by an increasingly invasive range of treatments including medications, injection therapy and the surgical insertion of a penile implant. Retrograde ejaculation is managed by medications to reverse the condition in mild cases and in bladder harvest of semen after ejaculation in more severe cases. Anejaculation might also be managed by medication in mild cases while assisted ejaculatory techniques including penile vibratory stimulation and electroejaculation are used in more severe cases. If these measures fail, surgical sperm retrieval can be attempted. Ejaculation with penile vibratory stimulation can be done by some spinal cord injured men and their partners at home, followed by in-home insemination if circumstances and sperm quality are adequate. The other options always require assisted reproductive techniques including intrauterine insemination or in vitro fertilization with or without intracytoplasmic sperm injection. The method of choice depends largely on the number of motile sperm in the ejaculate. PMID:22138899

    Full Text Available Purpose: We studied patient satisfaction about sexual activity after prosthesis implantation using validated questionnaires with the aim to discover if testicular prosthesis could be responsible of sexual dysfunctions (erectile dysfunction or premature ejaculation. Materials and Methods: We evaluated a total of 67 men who underwent radical orchiectomy for testicular cancer and a silicon testicular prosthesis implantation from January 2008 to June 2014 at our Hospital. These patients completed 5 validated questionnaires the day before orchiectomy and 6 months after surgery: the International Index of Erectile Function 5 (IIEF5, the Premature Ejaculation Diagnostic Tool (PEDT, the Body Exposure during Sexual Activities Questionnaire (BESAQ, the Body-Esteem Scale and the Rosenberg Self- Esteem Scale. We also evaluated 6 months after surgery any defects of the prosthesis complained by the patients. Results: The questionnaires completed by patients didn’t show statistically significant changes for erectile dysfunction (p > 0.05 and premature ejaculation (p > 0.05. On the contrary the psychological questionnaires showed statistically significant change for the BESAQ (p < 0.001 and the Body Esteem Scale (p < 0.001, but not for the Rosenberg Self-Esteem Scale (p > 0,05. A total of 15 patients (22.37% were dissatisfied about the prosthesis: the most frequent complaint (8 patients; 11.94% was that the prosthesis was firmer than the normal testis. Conclusions: Testicular prosthesis implantation is a safe surgical procedure that should be always proposed before orchiectomy for cancer of the testis. The defects complained by patients with testicular prosthesis are few, they don’t influence sexual activity and they aren’t able to cause erectile dysfunction or premature ejaculation.

    2015-12-01

    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.

No sexual activity at all was indicated by 23.1% at baseline and 21.8% after OCR, no problems with sexual activity by 40.8% at baseline and 38.6% after OCR. Patients showed an increase in specific problems (erectile dysfunction and lack of orgasm from 18% to 23% (<.0001 during OCR. We found the following independent positive and negative predictors of sexual problems after OCR: hyperlipidemia, age, CABG, baseline ExC and improvement of ExC, subjective physical and mental capacity, and sense of affiliation. Conclusions. Sexual dysfunction is present in over half of the patients undergoing OCR with no overall improvement during OCR. Age, CABG, low exercise capacity are independent predictors of sexual dysfunction after OCR.

  16. Dysfunctional voiding.

    Science.gov (United States)

    2002-01-01

    Wetting may be considered the Cinderella of paediatric medicine. Before discussing dysfunctional voiding, the milestones of the normal development of continence in the child and the definitions used to describe this topic are presented. Bladder storage requires (1): accommodation of increasing volumes of urine at low intravesical pressure and with appropriate sensation; (2): a bladder outlet that is closed and not modified during increase in intra-abdominal pressure; (3): absence of involuntary bladder contractions. Development of continence in the child involves three independent factors maturing concomitantly: (1) development of normal bladder capacity; (2) maturation of urethral sphincter function; (3) development of neural control over bladder-sphincter function. All these processes are discussed. Abnormalities of any of these maturational sequences, which run parallel and overlapping, may result in clinically evident abnormalities of bladder sphincter control. Although dysfunctional voiding (DV) in children is very common its prevalence has not been well studied and, to date, and its origin is not well known. In a correct evaluation of functional voiding we must take into account different elements: the bladder capacity (that increases during the first 8 years of life roughly 30 ml per year), the micturition frequency, post-void residual volumes, bladder dynamics, urinary flow rates. Thus the correct assessment of children with lower urinary tract dysfunction should include a detailed history. Signs of DV range from urge syndrome to complex incontinence patterns during the day and the night. In addition to incontinence problems, children may have frequency, urgency, straining to void, weak or interrupted urinary stream, urinary tract infections (UTIs) and chronic constipation with or without encopresis. DV are also referred in enuretic children who wet the bed more than one time per night and have a functional bladder capacity lower than attended for age

    Introduction Bisphenol A (BPA), released from plastics and dental sealants, is a suspected endocrine disruptor and reproductive toxicant. In occupationally exposed workers, BPA has been associated with erectile dysfunction (ED). Aims To determine whether long-term exposure to high doses of BPA in the rat affects serum levels of testosterone (T) and estradiol (E2), and induces corporal histopathology and resultant ED. Methods Young rats were injected intraperitoneal (IP) injection daily with BPA at 25 mg/kg/day or vehicle (n = 8/group). Erectile function was measured at 3 months by cavernosometry and electrical field stimulation (EFS). BPA was assayed in serum, urine, and penile tissue, and serum T and E2 were determined. Quantitative Masson trichrome, terminal deoxynucleotidyl transferase dUTP nick end labeling, Oil Red O, immunohistochemistry for calponin, α-smooth muscle actin, and Oct 4 were applied to penile tissue sections. Protein markers were assessed by Western blots and 2–D minigels, and RNA by DNA microarrays. Main Outcome Measures Erectile function, histological, and biochemical markers in corporal tissue. Results In the BPA-treated rats, total and free BPA levels were increased in the serum, urine, and penile tissue while serum T and E2 levels were reduced. In addition, the corpora cavernosa demonstrated a reduction in smooth muscle (SM) content, SM/collagen ratio, together with an increase in myofibroblasts, fat deposits, and apoptosis, but no significant change in collagen content or stem cells (nuclear/perinuclear Oct 4). In the penile shaft, BPA induced a downregulation of Nanog (stem cells), neuronal nitric oxide synthase (nitrergic terminals), and vascular endothelial growth factor (angiogenesis), with genes related to SM tone and cytoskeleton upregulated 5- to 50-fold, accompanied by changes in the multiple protein profile. However, both cavernosometry and EFS were unaltered by BPA. Conclusions While rats treated chronically with a high IP

    Aim The involvement of various penile structures in radiotherapy (RT)-induced sexual dysfunction among prostate cancer survivors remains unclear and domains beyond erectile dysfunction such as orgasm, and pain have typically not been considered. The purpose of this study was to investigate sexual dysfunction post-RT for localized prostate cancer and to examine whether radiation dose to different penile structures can explain these symptoms. Methods We investigated sexual dysfunction in two treated prostate cancer cohorts and in one non-pelvic-irradiated cohort, 328 sexually active men part of an unselected, population-based study conducted in 2008. The treated subjects were prescribed primary/salvage external-beam RT to 70 Gy@2.0 Gy/fraction. Absorbed RT doses (Dmean and Dmax) of the corpora cavernosa (CC), the penile bulb (PB), and the total penile structure (CC + PB) were related to 13 patient-reported symptoms on sexual dysfunction by means of factor analysis (FA) and logistic regression. Results Three distinct symptom domains were identified across all cohorts: “erectile dysfunction” (ED, two to five symptoms), “orgasmic dysfunction” (OD, two to four symptoms), and “pain” (two to three symptoms). The strongest predictor for ED symptoms was CC + PB Dmax (P = 0.001–0.03), CC and PB Dmean predicted OD symptoms equally well (P = 0.03 and 0.02–0.05, respectively), and the strongest predictor for pain symptoms was CC + PB Dmean (P = 0.02–0.03). Conclusion Sexual dysfunction following RT was separated into three main domains with symptoms related to erectile dysfunction, orgasmic dysfunction, and pain. Chances for intact sexual functionality may be increased if dose to the total penile structure can be restricted for these domains in the planning of RT. PMID:26564611

    This study investigated the attributional styles of men with and without sexual dysfunction for both positive and negative sexual and general events using a sex-specific version of the Attributional Style Questionnaire (Sex-ASQ), and ascertained the preliminary psychometric properties of the measure. The Sex-ASQ was created by embedding 8 hypothetical sexual events (4 positive, 4 negative) among the original 12 events in the Attributional Style Questionnaire (ASQ; C. Peterson, A. Semmel, C. von Baeyer, L. Y. Abramson, G. I. Metalsky, & M. E. Seligman, 1982). The Sex-ASQ was completed by 21 men with a principal DSM-IV diagnosis of Male Erectile Disorder (MED) and 32 male control participants. The psychometrics of the Sex-ASQ were satisfactory, but with the positive sexual event scales found to be less stable and internally consistent than the negative sexual event scales. Reasons for modest reliability of the positive event scales are discussed in terms of the original ASQ. As expected, men with MED did not differ significantly from men without sexual dysfunction in their causal attributions for general events, indicating that both groups exhibited an optimistic attributional style in general. Also as predicted, men with MED made more internal and stable causal attributions for negative sexual events than men without sexual dysfunction, and also rated negative sexual events as more important. For positive sexual events, the 2 groups did not differ in attributional style, with both groups making more external/unstable/specific causal attributions than for positive general events. Differences between explanatory style for sexual versus nonsexual events found in both sexually functional and dysfunctional men lend support for explanatory style models that propose both cross-situational consistency and situational specificity.

    Full Text Available Allgrove Syndrome or triple A syndrome is a rare familial multisystem disorder characterized by achalasia, alacrima and adrenal insufficiency. The objective was to describe a case of 4A syndrome where autonomic dysfunction was the presenting feature. A 22-year-old male presented with erectile dysfunction and loss of spontaneous morning erections for six months. He was having nocturnal diarrhea and recurrent postural dizziness for three months. He was found to have hyperpigmentation at pressure points, postural hypotension and other features of autonomic dysfunction. Laboratory investigations and imaging studies revealed hypoadrenalism, achalasia, alacrima and peripheral neuropathy. Autonomic neuropathy-related features persisted even after correction of hypoadrenalism. Based on clinical features and investigation he was diagnosed as a case of 4A syndrome presenting with autonomic dysfunction. Allgrove or 4A syndrome should be considered as a rare differential diagnosis of someone presenting with features of autonomic neuropathy.

    The link between lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) and sexual dysfunction is well established. Sexual dysfunction can encompass both ejaculatory dysfunction (EjD) and erectile dysfunction (ED). Ejaculatory dysfunction can consist of premature ejaculation, delayed ejaculation, retrograde ejaculation, anejaculation, decreased force of ejaculation and pain upon ejaculation. The impact of different medical and surgical therapies on ejaculatory function will be reviewed. We reviewed the various categories of LUTS treatment including the canonical epidemiology and pathophysiology as well as the surgical and medical treatments for LUTS/BPH. We note that most surgeries and several medical treatments have a certain but ill-defined negative impact on ejaculatory function. Several MISTs and selected medical therapies appear to have little impact on EjD. Both EjD and BPH are very common disorders in men under the care of an urologist. It is well documented that there is a clinical association between these two entities. Unfortunately many of the medical treatments and almost all surgical treatment impact the ejaculatory function of the patient. The surgical treatment of BPH often leads to retrograde ejaculation while medical treatment leads to anejaculation. PMID:27652217

    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.

    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.

    The aim of this retrospective observational study was to evaluate whether adding liraglutide to lifestyle changes, metformin (Met) and testosterone replacement therapy (TRT), by means of improving weight and glycaemic control, could boost erectile function in type 2 diabetic obese men with overt hypogonadism and erectile dysfunction (ED) in a 'real-life setting'. Forty-three obese, diabetic and hypogonadal men (aged 45-59 years) were evaluated because of complaining about the recent onset of ED. They were subdivided into two groups according to whether hypogonadism occurred after puberty (G1; n = 30: 25 with dysfunctional hypogonadism and 5 with acquired hypogonadotropic hypogonadism) or before puberty (G2; n = 13: 10 with Klinefelter's syndrome and 3 with idiopathic hypogonadotropic hypogonadism). Both G1 and G2 patients were given a combination of testosterone (T) [testosterone undecanoate (TU) 1000 mg/every 12 weeks] and Met (2000-3000 mg/day) for 1 year. In the poor responders (N) to this therapy in terms of glycaemic target (G1N: n = 16; G2N: n = 10), liraglutide (L) (1.2 μg/day) was added for a second year, while the good responders (Y) to T + Met (G1Y: 14/30 and G2Y: 3/13) continued this two drugs regimen therapy for another year. All patients were asked to fill in the International Index of Erectile Function (IIEF 15) questionnaire before starting TU plus Met (T1) and after 12 months (T2) and 24 months (T3) of treatment. Patients underwent a clinical examination and a determination of serum sex hormone binding globulin (SHBG), total testosterone (T) and glycosylated haemoglobin (HbA1c) at T1, T2 and T3. At T2, each patient obtained an improvement of ED (p 7.5% (>58 mmol/mol)], while T turned out to be within the range of young men. L added to TU and Met regimen in G1N and G2N allowed these patients to reach not only the glycaemic target [HbA1c = <7.5% (<58 nmol/mol)] and a significant reduction in body weight (p < 0.01), but also a further increase in SHBG

    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.)

    Full Text Available Sexual dysfunction (SD is a health problem which occurs during any phase of the sexual response cycle that keeps the individual or couple from experiencing satisfaction from the sexual activity. SD covers a wide variety of symptoms like in men, erectile dysfunction and premature or delayed ejaculation, in women, spasms of the vagina and pain with sexual intercourse, in both sexes, sexual desire and response. And pharmacopuncture, i.e. injection of subclinical doses of drugs, mostly herb medicine, in acupoints, has been adopted with successful results. This case report showed the effect of bee venom on SD. A 51-year-old male patient with SD, who had a past history of taking Western medication to treat his SD and who had previously undergone surgery on his lower back due to a herniated disc, received treatments using pharmacopuncture of sweet bee venom (SBV at Gwanwon (CV4, Hoeeum (CV1, Sinsu (BL23, and Gihaesu (BL24 for 20 days. Objectively, the patient showed improvement on most items on the International Index for Erectile Dysfunction (IIEF like 28 to 29 out of perfect score 30 for erectile function, 10 to 10 out of perfect score 10 for orgasmic function, 6 to 8 out of perfect score 10 for sexual desire, 10 to 13 out of perfect score 15 for satisfaction with intercourse, and 6 to 8 out of perfect score 10 for overall satisfaction; subjectively, his words, the tone of his voice and the look of confidence in his eyes all indicated improvement. Among the variety of effects of SBV pharmacopuncture, urogenital problems such as SD may be health problems that pharmacopuncture can treat effectively.

    It has been generally assumed that partner's erectile dysfunction, premature, and delayed ejaculation play a significant role in determining female sexual dysfunction (FSD). This study aimed to evaluate the role of the male partner's sexual function, as perceived by women, in determining FSD. A consecutive series of 156 heterosexual women consulting our clinic for FSD was retrospectively studied. All patients underwent a structured interview and completed the Female Sexual Function Index (FSFI). FSFI total score decreased as a function of partner's age, conflicts within the couple, relationship without cohabitation and the habit of engaging in intercourse to please the partner; FSFI total score increased as a function of frequency of intercourse, attempts to conceive and fertility-focused intercourse. FSFI total score showed a negative, stepwise correlation with partner's perceived hypoactive sexual desire (HSD) (r = -0.327; p libido, FSFI total score was significantly lower when their partner's libido was low (p = 0.041); the correlation disappeared if the patient also experienced HSD. In conclusion, the presence of erectile dysfunction, premature, and delayed ejaculation of the partner may not act as a primary contributing factor to FSD, as determined by FSFI scores; conversely, women's sexuality seems to be mostly impaired by the perceived reduction in their partner's sexual interest.

    Sex has always been a taboo subject in Asian society. However, over the past few years, awareness in the field of men's sexual health has improved, and interest in sexual health research has recently increased. The epidemiology and prevalence of erectile dysfunction,hypogonadism and premature ejaculation in Asia are similar in the West. However, several issues are specific to Asian males, including culture and beliefs, awareness, compliance and the availability of traditional/complementary medicine. In Asia, sexual medicine is still in its infancy, and a concerted effort from the government, relevant societies, physicians and the media is required to propel sexual medicine to the forefront of health care.

    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.
