    The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy,unparalleled to any previous visual loop or magnification techniques.This technology revolutionized techniques for microsurgery in andrology.Today,we may be on the verge of a second such revolution by the incorporation of robotic assisted platforms for microsurgery in andrology.Robotic assisted microsurgery is being utilized to a greater degree in andrology and a number of other microsurgical fields,such as ophthalmology,hand surgery,plastics and reconstructive surgery.The potential advantages of robotic assisted platforms include elimination of tremor,improved stability,surgeon ergonomics,scalability of motion,multi-input visual interphases with up to three simultaneous visual views,enhanced magnification,and the ability to manipulate three surgical instruments and cameras simultaneously.This review paper begins with the historical development of robotic microsurgery.It then provides an in-depth presentation of the technique and outcomes of common robotic microsurgical andrological procedures,such as vasectomy reversal,subinguinal varicocelectomy,targeted spermatic cord denervation (for chronic orchialgia) and robotic assisted microsurgical testicular sperm extraction (microTESE).

    Appropriate physical activity is one of the bases of healthy lifestyle. In fact, physical exercise and playing sport may be associated with both improvements and injury to both general and reproductive health. A biologically normal testosterone secretion appears fundamental in males to guarantee both a physiological exercise adaptation and safe sport participation. The reproductive system is highly sensitive to the effects of exercise-related stress and the reproductive hormones may both increase and decrease after different acute or chronic exercises. Exercise and sport participation may positively or negatively influence andrological health status depending on the type, intensity and duration of performed physical activity and on individual health status. In addition, prohibited substances administration (e.g. androgenic-anabolic steroids, and so forth) in competitive and non-competitive athletes represents the main cause of iatrogenic andrological diseases. Preventing and treating andrological problems in active healthy and unhealthy individuals is as important as promoting a correct lifestyle. Physicians need to be educated on the relationships between the male reproductive system and sport participation and on the great role of the pre-participation physical examination in the prevention of andrological diseases.

    Patients with very low sperm count through direct sperm examination can exhibit extreme oligozoospermia or cryptozoospermia (after centrifugation). The management of these patients is a real challenge for both clinicians and biologists. In this retrospective and comparative cohort study, we compared the andrological phenotype of patients with extreme alterations of spermatogenesis and assessed whether the origin of spermatozoa (testicular or ejaculate) had any influence on intracytoplasmic sperm injection (ICSI) outcomes. A total of 161 ICSI cycles were performed using ejaculated spermatozoa from 75 patients with extreme oligozoospermia (EOS) or cryptozoospermia (CS) and 150 ICSI cycles using extracted testicular spermatozoa from 74 patients with non-obstructive azoospermia (NOA). Physical, hormonal, ultrasound assessments, and ICSI outcomes were performed in each group. Cryptorchidism was significantly more frequent in the NOA group (60.8% vs. 22.6%, p = 0.001). FSH levels were significantly higher [18.9 IU/L (5.9-27.0) vs. 15.3 IU/L (9.0-46.5), p = 0.001] and the majority of inhibin B levels measured were found mostly undetectable in the NOA group as compared to EOS/CS group (31.1% vs. 10.7%, p = 0.0004). Moreover, we found no significant differences in the respect to the fertilization rates (48.9% and 43.3%, p = 0.43), implantation rates (17.4% and 15.9%, p = 0.77), and percentage of top quality embryo (22.4% and 20.4%, p = 0.73) between the two groups. The clinical pregnancy rates per embryo transferred were comparable in both groups (28.3% and 27.4%, p = 0.89). In this study, we showed for the first time a different andrological phenotype between EOS/CS and NOA groups. Indeed, cryptorchidism was significantly more frequent with more severe endocrine parameters found in the NOA group. These results reflect a more profound alteration in spermatogenesis in NOA patients. However, there was no difference in ICSI outcomes between NOA and EOS

    The purpose of this investigation was to study the interrelation of andrological status with anthropometric and hormonal descriptions for age-specific features discovery of male sexual system pathological states at technical college students. 147 adolescents aged 15-17 years old were examined. Only 41 of them were found to have no abnormalities in their genital system development; in 35 adolescents sexual development was delayed; and 97 adolescents were found to have various andrological diseases (varicocele, phimosis, gynecomastia, testicular asymmetry, etc.) or clinical signs for development of these diseases. In 26 adolescences delayed sexual development was combined with the andrological pathology. The normal andrological status was usually accompanied with the highest frequency of low values of anthropometric indicators and indices that reflect the influence of various hormonal systems on the bodily constitution, as well as expressed anthropometricheterogeneity. In adolescents with andrological pathology or clinical signs for its development, in all anthropometric parameters the higher values were seen more frequently than low values against the background of highest group anthropometric homogeneity. Summative anthropometric characteristics of the adolescents group with delayed sexual development were between those of the adolescents groups with normal andrological status and andrological pathology The number of correlational relationships of anthropometric and hormonal indicators with the levels of cortisol and dehydroepiandrosteronesulphate was the lowest in the group of adolescents with normal andrological status as compared to their peers with delayed sexual development and andrological pathology. Only in the group of adolescents with normal andrological status the correlation analysis of data showed physiological influence of sexual hormones on anthropometric indicators. Thus, lower influence of sexual system hormones during this ontogenesis stage

    Full Text Available Aiming to determine the relationship between the frequency of testicular shape and the andrological aspects in young Nellore bulls, 18,676 animals were assessed. All andrological examinations were performed between the years 2000 and 2008. Animals were classified as able for breeding, able for breeding in natural mating system, unable for breeding and discarded. The testicular shape was classified as long, fairly long, oval-long, spherical-oval, and spherical. The analysis of Pearson correlations was performed for testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major defects, minor defects and total defects. Testicles with oval shape prevailed (99.61%. It was obseved that 76.34; 66.34; 64.34; 58.33 and 50.00% of the animals were classified as sound for breeding for shapes long, fairly long, oval-long, spherical-oval, and spherical, respectively. Correlations between testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major, minor and total defects were 0.26; 0.08; 0.00; 0.11; -0.02; 0.02 and -0.01, respectively. Testicular shape had no influence upon the andrological examination results. Testicles of long shape were prevalent within the population.

    Aim: To pursue whether cytogenetic aberrations correlate with specific spermatological or hormonal abnormalities.Methods: 305 infertile couples were investigated. All male partners were referred to a complete andrological workup with physical examination, determination of hormones, HIV testing and semen analysis. Cytogenetic analysis was carried out in both partners by means of standard techniques using cultured lymphocytes from peripheral blood. Results: Among the 305 couples, 10 men (3.2%) and 10 women (3.2%) showed constitutional chromosomal aberrations, including reciprocal translocations (n=7), Robertsonian translocations (n=3), inversions (n=3), other structural aberrations (n=4) and sex chromosome aberrations (n=3). In addition to the impaired sperm count in most of the patients, a tendency to an increased proportion of spermatozoa with acrosome defect was observed. Conclusion. Chromosomal aberrations may contribute to the low fertilization and pregnancy rates in the infertile couples.(Asian J Androl 2000 Dec;2:293-296)

    For centuries, difficulties have occurred in determining unresolved paternities. In addition to the modern standard methods, such as the examination of DNA or serological proof, expert opinion on fertility once played an important role. The andrological difference between incapability to fertilise and the inability to participate in sexual intercourse was also distinguished historically. Of special significance was the discovery of spermatozoa by the medical student Johan Ham in 1677 and their further investigation by Antoni van Leeuwenhoek.Recently, modern DNA methods have also been applied for historical investigations. Illustrious examples are the DNA analysis in the case of Kaspar Hauser of Ansbach and the dispute about Thomas Jefferson, President of the U.S., fathering a child by one of his slaves. In this discourse, a medicinal-forensic review of the development of expert opinion, illustrated with historical case studies, is given.

    Aim: To improve workflow and usability by introduction of a new electronic patient record (EPR) and database.Methods: Establishment of an EPR based on open source technology (MySQL database and PHP scripting language)in a tertiary care andrology center at a university clinic. Workflow analysis, a benchmark comparing the two systems and a survey for usability and ergonomics were carried out, Results: Worlflow optimizations (electronic ordering of laboratory analysis, elimination of transcription steps and automated referral letters) and the decrease in time required for data entry per patient to 71% ± 27%, P<0.05, lead to a workload reduction. The benchmark showed a significant performance increase (highest with starting the respective system: 1.3 ± 0.2 s vs. 11.1 ± 0.2 s, mean ± SD). In the survey, users rated the new system at least two ranks higher over its predecessor (P<0.01) in all sub-areas.Conclusion: With further improvements, today's EPR can evolve to substitute paper records, saving time (and possibly costs), supporting user satisfaction and expanding the basis for scientific evaluation when more data is electronically available. Newly introduced systems should be versatile, adaptable for users, and workflow-oriented to yield the highest benefit. If ready-made software is purchased, customization should be implemented during rollout.

    Full Text Available In addition to the annual report of the German IVF Registry (D·I·R the database of 498,784 ART cycles between 1998 and 2008 was analysed for aspects regarding andrology, medical and economical aspects of ICSI and stimulation with gonadotropins. The indication for an ICSI procedure is related to the retrieval of sperm. Seven percent of all ART cycles in the DIR are already performed with epididymal or testicular sperm due to azoospermia. The analysis of cycles with testicular sperm revealed that fertilisation and pregnancy rates are reduced in comparison to ejaculated or frozen sperm, but miscarriage and birth rates do not increase. The data recording of lifestyle parameters can be valuable in the future. The analysis of the D·I·R data demonstrates that restrictions on the reimbursement for ART cycles have significant impact on the use of IVF and ICSI treatments. Medical indications rather than economic reasons seem to be responsible for the increase in ICSI treatment. Since the commercial launch of GnRH antagonists in 1999 and 2000 more than 90 % of IVF and ICSI protocols in Germany are now performed with GnRH agonists (54.8 % and GnRH antagonists (31.5 %. Approximately 90% of the IVF and ICSI cycles in Germany are performed with recombinant FSH (rFSH, highly purified menotropin (HP-hMG or a combination of both. Non-medical factors can influence the choice of gonadotropins for stimulation. Women beyond the age of 34 probably have better IVF or ICSI outcome when the stimulation is performed with rFSH. J

Foram utilizados 14 touros, todos classificados como aptos à reprodução, após exame andrológico, CAP e observação do comportamento sexual a campo durante 12 horas. Onze touros foram avaliados em manejo individual, com proporção média touro:vaca de 1:46, e os três restantes, em manejo múltiplo, com proporção média touro:vaca de 1:23. A pontuação média obtida pela CAP foi 78,92 ± 8,92 (muito bom e o escore, 9,85 ± 0,36 (excelente para libido. Quanto maior o tempo de teste, maiores foram os escores da libido.

    Determination of maikers of sperm function, accessory sex gland secretion and silent male genital tract inflammation is of considerable diagnostic value in the evaluation of male infertility. The introduction of biochemical tests into the analysis of male factor has the advantage that standardized assays with a coefficient of variafion characteristic of clinical chemistry are performed, in contrast to biological test systems with a large variability .Biochemical parameters may be used in clinical practice to evaluate the sperm fertitizing capacity (acrosin, aniline blue,ROS), to characterize male accessory sex gland secretinns (fructose, a-glucosidase, PSA), and to identify men with silent genital tract inflammation (elastase, C'3 complement component, coeruloplasmin, IgA, IgG, ROS).

    Penile and testicular tumors, especially those of the malignant nature, usually require radical excision, which alters the organ image, affects sexual and urinary functions, and consequently undermines the self-confidence and quality of life of the patient. Recent studies show that organ-sparing surgery can be an alternative to radical excision for superficial tumors and small masses. Penis-sparing surgery (PSS) has been indicated for superficial penile cancer, such as Tis and T1a lesions, and testis-sparing surgery (TSS) is feasible for benign small bilateral or solitary testicular masses (TIN). Long-term follow-ups after PSS or TSS show that the patients may retain a satisfactory appearance of the organ as well as desirable sexual and reproductive functions.

    Population aging is continuously increasing in Italy and in the World. Individuals aged 60 years or more are currently 10,500,000 and will be 13,000,000 in 2015. Life quality in geriatric ages includes the maintenance of sexual power: according to recent data (Carrol et al., 1992), 80% of impotence cases are due to organic causes. In addition, the use of drugs can cause impotence. Among them tiazidic diuretics may cause an increase of sexual disturbances. Other drugs with this potential are digitalis, antihypertensive drugs (particularly beta blockers), major and minor tranquillizers, antidepressant, H2 receptor antagonists, antiparkinsonian cholinergic drugs and estrogens employed in the treatment of prostate tumors. Diseases of geriatric age that can alter sexual power are diabetes mellitus, ischemic heart disease for the accompanying depression and for the use of antidepressants; severe hypertension is complicated by impotence in 15% of cases. Among neurological diseases Parkinson's disease and multiple sclerosis can be causes of sexual dysfunctions. Patients on hemodialysis can be impotent, with recent data (Soloh et al 1992) showing that erythropoietin treatment of anemia also improve sexual dysfunctions. Prevention from a geriatric standpoint should be base on action on known risk factor as smoking, alcohol abuse and dislipidemias and with the activation of a close drug vigilance.

    Stem cells hold great promise for regenerative medicine because of their ability to self-renew and to differentiate into various cell types. Although embryonic stem cells (BSC) have greater differentiation potential than adult stem cells, the former is lagging in reaching clinical applications because of ethical concerns and governmental restrictions.Bone marrow stem cells (BMSC) are the best-studied adult stem cells (ASC) and have the potential to treat a wide variety of diseases, including erectile dysfunction (ED) and male infertility. More recently discovered adipose tissue-derived stem cells (ADSC) are virtually identical to bone marrow stem cells in differentiation and therapeutic potential,but are easier and safer to obtain, can be harvested in larger quantities, and have the associated benefit of reducing obesity. Therefore, ADSC appear to be a better choice for future clinical applications. We have previously shown that ESC could restore the erectile function of neurogenic ED in rats, and we now have evidence that ADSC could do so as well. We are also investigating whether ADSC can differentiate into Leydig, Sertoli and male germ cells. The eventual goal is to use ADSC to treat male infertility and testosterone deficiency.

    Full Text Available Varicocele is a common medical condition entangled with many controversies. Though it is highly prevalent in men with infertility, still it marks its presence in males who do have normal fertility. Determining which patients are negatively affected by varicocele would enable clinicians to better select those men who benefitted the most from surgery. Since conventional semen analysis has been limited in its ability to evaluate the negative effects of varicocele on fertility, a multitude of specialized laboratory tests have emerged. In this review, we examine the role and significance of specialized sperm function tests with regards to varicocele. Among the various tests, analysis of sperm DNA fragmentation and measurements of oxidative stress markers provide an independent measure of fertility in men with varicocele. These diagnostic modalities have both diagnostic and prognostic information complementary to, but distinct from conventional sperm parameters. Test results can guide management and aid in monitoring intervention outcomes. Proteomics, metabolomics, and genomics are areas; though still developing, holding promise to revolutionize our understanding of reproductive physiology, including varicocele.

    Early in his investigations, Leeuwenhoek (1670s)1 deduced that spermatozoa were alive and an integral part of semen, rather than artifacts or parasites. He eventually observed spermatozoa in the semen of men, dogs, horses, birds, fishes, amphibians, molluscs, and many insects, and concluded that they must be a universal feature of male reproduction. The huge differences in sperm form among species have been discussed in relation to evolutionary changes dictated by the egg and its investments.2 Spallanzani (1800s)1 was the first scientist to develop successful methods for artificial insemination, first with amphibians and later with dogs. With these experiments, he showed that physical contact between intact spermatozoa and ova was necessary to achieve the fertilization. Some years later (1820s), Prévost and Dumas1 performed the defining experiment to identify correctly the function of spermatozoa in reproduction. PMID:27633908

    This study was aimed at evaluating the association between seminal plasma interleukin-8 (sIL-8) and colour-Doppler ultrasound (CDU) characteristics of the male genital tract in a series of patients fulfilling the criteria of male accessory gland infections (MAGI). Of 250 subjects seeking medical care for couple infertility, 79 (mean age: 36.4 ± 7.5 years) met the criteria of MAGI and scored higher than the rest of the sample on the National Institutes of Health-Chronic Prostatitis Symptom Index score. All patients underwent simultaneous hormone evaluation and seminal analysis (including sIL-8), along with scrotal and transrectal CDU before and after ejaculation. After adjusting for age, sIL-8 in patients with MAGI was significantly related to several abnormal semen and CDU parameters. In particular, leucocytospermia was closely associated with sIL-8. Ejaculate volume, unlike other semen or hormonal parameters, was negatively associated with sIL-8. When scrotal CDU was performed, sIL-8 was positively related to CDU inhomogeneous, hypo-echoic, hyper-echoic epididymis and to epididymal calcifications. In addition, a positive correlation among sIL-8, hyperaemic epididymis and an increased size of epididymal tail was found. When transrectal CDU was performed, an association among sIL-8 and hyper-echoic seminal vesicles, dilated ejaculatory ducts and duct calcifications was also observed. Finally, sIL-8 was positively related to prostate CDU abnormalities such as calcifications, inhomogeneous/hypo-echoic texture, hyperaemia and high arterial blood flow. No association was found with testis parameters. In conclusion, sIL-8 levels in patients with MAGI are associated with several parameters and CDU abnormalities of epididymis, seminal vesicles, ejaculatory ducts and prostate, but not of the testis. Furthermore, sIL-8 positively correlates with CDU signs of ejaculatory duct inflammatory subobstruction.

    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

    @@ The progression of cells from a normal differentiated state in which the rates of proliferation and apoptosis are in check, to a tumorigenic and metastatic state where these rates are imbalanced, likely involves the accumulation of mutations in multiple genes, and the evolution and clonal selection of more aggressive phenotypes. These events are associated with changes in the expression of numerous gene products including the transient receptor potential (TRP) proteins. TRP proteins are a family of Ca2~- and Na+-permeable channels that play a diverse and important role in cellular physiology and pathology. One member of this family, TRPM8, a receptor-activated non-selective cation channel is highly expressed in prostate cancer (PCa) cells and in recent years, has emerged as a promising prognostic marker and putative therapeutic target in PCa.

    Purpose: the contribution of a functional imaging examination is expected by the andrology and urology community in the situations of masculine infertility (especially after chemotherapy). The spermatogonia, responsible of cells populations renewal, catch the F.D.G. tracer through GLUT3 receptors. To date, PET/CT with F.D.G. has never been used for functional study of testes with andrology aim. The objective is to search an eventual correlation between the F.D.G. testes uptake and spermatology examination. Conclusions: This preliminary study shows that among men without any known testes pathology, there is a significant correlation between the F.D.G. testes uptake and the principal parameters of masculine fertility. If these results are confirmed, clinical applications could appear in the diagnosis and prognosis exploration of hypo fertility. (N.C.)

    Since release of the latest WHO manual with the new lower reference values of semen parameters, a lot of discussion has been raised about their usefulness and appropriateness for assessment of male fertility. As with the previous reference values the new limits do neither allow an andrological diagnosis based on nosological criteria nor clear-cut differentiation between fertility and sub-/infertility.Therefore, considering the fact that fertility is a continuum, the new lower reference limits should not be overestimated. Most probably,more sperm function tests, such as determination of DNA integrity, and-in the future-assessment of biomarkers, such as sperm proteomics will be included into andrological work-up, thus resulting in a more personalized approach of infertility management. On the other hand, the detailed instructions for standard and advanced semen analysis provided in the new manual are very much appreciated and should be adopted by each seriously working laboratory.

Several studies have already investigated the presence of PD in young men, and these studies reported a PD prevalence that varies between 1.5% and 10.8%. Having noticed a greater number of young patients in our centers in recent years, we decided to carry out a retrospective study to evaluate the prevalence of PD in patients aged <40 years, as well as to investigate any possible difference in evolution based on the age of PD patients. We selected a sample of patients (n=271 with a similar time of onset of disease. We then stratified all 271 patients into two groups: group A (age <40 years [n=46] and group B (age ≥40 years [n=225]. All 271 patients were evaluated for the following variables: penile plaque volume, degree of penile curvature, penile pain, and erectile function. Plaque volume was measured in cm3 by dynamic penile color Doppler sonography after administration of intracavernosal alprostadil 10 mcg. The number of younger patients was 46, accounting for 16.9% of the whole sample. Our study showed more frequent appearance and greater progression of penile curvature in younger patients.

    PET/CT using {sup 18}F-FDG is a well-established diagnostic examination in oncology, cardiology and neurology. The clinical significance of nontumoral testicular uptake of FDG is unknown. Functional testicular imaging may have important clinical applications in the diagnosis and prognosis of male infertility. The aim of this study was to determine the andrological value of a FDG PET/CT in analysing testicular function, by correlating the PET/CT data with the sperm parameters. Retrospective analysis of FDG PET/CT in 20 consecutive cancer patients without testicular pathology in whom two semen samples had been obtained for analysis before any chemotherapy. FDG PET/CT parameters were the mean standardized uptake value (SUVmean), used for measuring the intensity of uptake, and the functional testicular volume (FV). For statistical analysis, a Spearman's rank correlation test and a Mann-Whitney test were used. Of 20 patients (mean age 22 years), 18 had provided two sperm samples for cryopreservation. Sperm concentration was above 20 x 10{sup 6}/ml in 55% of the patients. The intensity of uptake and the FV were correlated with the total sperm count, the sperm concentration and motility (p < 0.05). The difference in SUVmean between the two testes showed an inverse correlation with sperm concentration (p = 0.036). Normospermic and oligospermic men had significant differences in: (1) mean SUVmean, (2) mean FV, and (3) the difference in intensity of uptake between the testes (p < 0.05). This is the first report on the andrological value of FDG PET/CT in analysing nontumoral testicular function. This pilot study showed a significant correlation between intensity of uptake of FDG and testicular FV with the main sperm parameters. PET/CT with FDG could become a useful new tool in assisted reproductive technologies and other andrological or urological applications. (orig.)

    Full Text Available Objective: To assess the proportion of patients with Peyronie’s Disease (PD and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. Materials and methods: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD, the second one composed by patients with other andrological diseases (control arm. For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated questionnaires to determine the erectile function status by the International Index of Erectile Function 5 (IIEF-5 and the pain status during erection by the Visual Analogue Scale (VAS. A univariate analysis was conducted using R software. Results: We enrolled 279 consecutive patients. The number of PD patients was 97 (34,7%. The univariate analysis showed a correlation between PD and cigarette smoking (p = 0.0242, blood hypertension (p < 0.001, erectile dysfunction (p < 0.001. No significant association was observed between diabetes and PD (p = 0.358. The median age of PD arm was 60 years and the median age of the control arm was 63,5 years; therefore the median age of PD arm resulted lower than the median age of the control arm (p = 0,031. Conclusions: Peyronie’s disease is more common than we might think; furthermore it can be diagnosed among young patients. According to our results, cigarette smoking and blood hypertension may be considered statically significant risk factors for developing PD. On the contrary diabetes seems not to be a risk factor for PD. According to our results PD should be sought also in young patients. Further studies are necessary to confirm that removing the indicated risk factors may reduce the incidence of PD.

Based on the current epidemiological and experimental data, most common etiological factors of gynecomastia were investigated. A multiple-valued role of various causes of gynecomastia in several age-groups was revealed. Literature data show that gynecomastia may be a manifestation of various diseases: endocrine, genetic, systematic. As well as that, gynecomastia may occur in patients with oncological diseases. However, gynecomastia can be an iatrogenic complication. Currently, we continue to make insights to the problem of gynecomastia in order to be able to classify its etiological factors and determine its basic pathogenesis pathways.

    Urology has always been seen as being on the cutting edge of technology and this has been especially prevalent in the past 10 to 15 years with a move to robotic surgery, increased use of laser technology, and stem cell research leading to organ regeneration. Urology has a number of subspecialties including pediatrics, urologic oncology, renal transplantation, male infertility and andrology, calculi, female urology, neurourology, and trauma and reconstruction. Urologists have a wide array of practice options ranging from performing major oncologic procedures with extensive reconstruction to having an office-based practice and performing endoscopic cases with everything else in between. Subspecialization is becoming increasingly more organized and regulated.

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

    This study aimed to report penile dimensions in adult Egyptian males consulting for small-sized penis (SSP) and describe their demographics and andrological profile. A case control study was designed through retrospective data analysis of patients (n = 239) seeking advice for SSP and a control group (n = 59). This included sociodemographics, other andrological complaints, and penile dimensions (pendulous length [PL], penopubic or total length [TL], and circumference [CF]) at flaccid and erect states and the size of the prepubic fatty pad. The results reported that most patients were single, students, and smokers and had not completed a university education. Several patients reported falsely premature ejaculation (PE), penile curvature (PC), and small-sized testes. Most penile dimensions of the patients (mean, cm) were significantly lower than those of the controls, whether in flaccid (PL: 7.4 vs. 8.05, p = .008; CF: 8.7 vs. 8.98, p = .026) or erect state (PL: 11.8 vs. 13, p = .000; TL: 14.2 vs. 15, p = .000; CF: 11.3 vs. 11.8, p = .003). However, no patient presented with a pendulous penile length <4 cm in flaccid or <7 cm in erect state. In conclusion, Egyptian men consulting for SSP did not have true small organs, but their penile dimensions were slightly smaller than those of men without such complaint. The proper sexual education program is highly advisable in these situations to avoid the myths and misconceptions about sexuality.

    Objective To determine if men with azoospermia are at an elevated risk of developing cancer in the years following an infertility evaluation. Design Cohort Study Setting United States andrology clinic Patients 2,238 men with complete records were evaluated for infertility at a single andrology clinic in Texas from 1989 to 2009. Interventions None Main Outcome Measures Cancer incidence was determined by linkage to the Texas Cancer Registry. Results In all, 451 men had azoospermia and 1,787 were not azoospermic with a mean age at infertility evaluation of 35.7 years. Compared to the general population, infertile men had a higher risk of cancer with 29 cases observed compared with 16.7 expected (SIR 1.7, 95% CI 1.2–2.5). When stratifying by azoospermia status, azoospermic men had an elevated risk of cancer (SIR 2.9, 95% CI 1.4–5.4). Infertile men without azoospermia had a trend towards a higher rate of cancer (SIR 1.4, 95% CI 0.9–2.2). The Cox regression model revealed that azoospermic men had 2.2-fold higher cancer risk compared to not azoospermic men (HR 2.2, 95% CI 1.0–4.8). Conclusions Men with azoospermia have an increased risk of subsequently developing cancer, suggesting a possible common etiology between azoospermia and cancer development. Additional follow-up of azoospermic men after reproductive efforts end may be warranted. PMID:23790640

    Genetic aspects of male infertility and the possible risks of new assisted reproduction and their influence on the development of zygotes and children born after intracytoplasmic sperm injection (ICSI) need further research. These patients have an increased risk of diploidy, and disomies are frequent in their spermatozoa. Meiotic disorders are more common in testicular biopsies of patients with severe oligoasthenozoospermia. For these reasons, a detailed andrological study is absolutely mandatory before accepting a couple with these characteristics into an IVF-ICSI programme. When an andrological patient has plasma FSH values >10 IU/l and/or very low total motile sperm count meiotic study in order to rule out meiotic arrest or synaptic anomalies. Another important aspect to be considered is the possible benefit of applying preimplantation genetic diagnosis in these cases because they normally have a high percentage of chromosomally abnormal embryos, although in the present study this was not evident. All studies agree on the necessity of conducting follow-up studies in the population of children born after IVF-ICSI. In this way, it will be possible to find out if these infertile patients and their offspring have a higher risk of suffering epigenetic errors and imprinting disorders.

    The bull breeding soundness evaluation (BBSE) has evolved as a cost-effective veterinary procedure which provides benefits such as risk-reduction and improvements in strategic bull usage, herd fertility and economics. Semen evaluation is an important component of the BBSE when performed appropriately; a consideration that is increasingly addressed by third party andrology laboratories. The combination of competent physical/reproductive exams (including scrotal circumference measurements) and semen evaluations can contribute greatly to the fertility and economics of individual herds as well as adding to understanding of those factors which affect cattle fertility. Despite such advantages, there remain challenges in achieving full acceptance of BBSEs, particularly by the dairy industry and in developing countries.

    There is a paucity of published literature on the andrological consequences of urethral repair. Until recently authors have focused mainly on technical aspects and objective results. Reported outcomes of urethral reconstruction surgery have traditionally focused only on urodynamic parameters such as flow rates. Patient reported outcome measures have largely been neglected and there is a scarcity of well conducted systematic studies on the subject. For these reasons whether the different components of sexual life are more or less affected by different types of urethral reconstruction remains largely unknown. In an attempt to clarify the available scientific evidence, the authors make a critical review of available literature, systematizing it by sexual domain and study type. Brief pathophysiological correlations are discussed. PMID:27051420

Fertility of the bulls is evaluated with andrological examinations and semen analyses, such as morphology. However, little attention has been paid to the inheritance of bull fertility. In this study, we correlated sperm morphology, birth year and station of 695 AI bulls with calving rate (CR). Sperm morphology was clearly associated with CR underlining the usefulness of morphological examination in the assessment of fertility. The correlation between the proportion of normal spermatozoa and CR was significant (p bulls with the CR of their 27 sires to study the inheritance of fertility. Sire's CR did not correlate with the CR of the sons (p = 0.218). This result indicates that at least when sires of acceptable CR are used to produce sons for use in AI the inheritance of CR is not significantly correlated.

    Full Text Available Introduction: Few studies on the prevalence of male sexual diseases are currently available due to difficult application of observational studies or andrological disease prevention campaigns on large series of apparently healthy subjects. The medical check-up linked to compulsory military service represented in Italy a valid tool for epidemiological and observational study for 18 year old boys from 1861 to 2004. The stopping of compulsory military service and its related medical check-up could have determined an important social impact in terms of a lower level of attention and care on male genital/sexual diseases. The aim of the present observational study was to check the prevalence of genital/ sexual diseases among young male high-school students and promote an alternative campaign of information among young students. Methods: A prospective observational analytical study on young male students was conducted by 6 urological centres. Genital and sexually transmitted diseases were presented with slides to students in a general assembly. Some students were then counselled and filled out a short questionnaire on their lifestyle. Results: 12,535 students (10,432 males-83.6% followed the presentation. and 4,897 males (46.7% decided to be checked-up by the urologist and out of them 1554 (31.7% presented relevant andrological diseases. Five-hundred students completed the questionnaire concerning their lifestyle. Many of them had not yet experienced condom use during sexual intercourse (27.8%. Drug abuse was reported by 39.6% of subjects and alcohol consumption in 80.8% of them. Conclusions: These data suggest the need for a national information campaign on male sexual disorders to promote sexual health.

    Background Pharmacological therapy has been considered as the first-line treatment for patients with uncomplicated benign prostatic hyperplasia (BPH). The aim of this study was to evaluate the efficacy and safety of tamsulosin compared with a placebo for treating BPH. Methods The randomized placebo-controlled trials (RCT) of tamsulosin for the treatment of BPH from all over the world were searched. PubMed, Ovid, ScienceDirect, EBSCO, CBM, and CNKI were searched, as well as a manual search of four Chinese journals: Chinese Journal of Andrology, National Journal of Andrology, Chinese Journal of Urology, and Journal of Clinical Urology was also performed. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross-checking. Divergences of opinions were settled by discussion. Meta-analysis was processed by Rev Man 5.0 software, fail-safe number was performed by SAS8.0 software. Results Seven RCTs involving 2455 men met the inclusion criteria. The basic characteristics of patients were comparable in all the studies. Comparing three common criteria: international prostate symptom score (IPSS)/Boyarsky symptom score, maximum flow rate (MFR), quality of life (QOL), tamsulosin was better than placebo at improving IPSS and MFR, with no significant difference in the QOL. Adverse events of tamsulosin also showed no significant difference from the placebo group (Z=1.62, P=0.10, OR=1.22, 95% CI 0.96-1.54).Conclusions Tamsulosin is better than placebo at improving IPSS and MFR. Adverse events of tamsuloisn show no significant difference compared with placebo. More high quality trials with larger samples and longer follow-up are proposed.

    Full Text Available Abstract The onset of clinical assisted reproduction, a quarter of a century ago, required the isolation of motile spermatozoa. As the indication of assisted reproduction shifted from mere gynaecological indications to andrological indications during the years, this urged andrological research to understand the physiology of male germ cell better and develop more sophisticated techniques to separate functional spermatozoa from those that are immotile, have poor morphology or are not capable to fertilize oocytes. Initially, starting from simple washing of spermatozoa, separation techniques, based on different principles like migration, filtration or density gradient centrifugation evolved. The most simple and cheapest is the conventional swim-up procedure. A more sophisticated and most gentle migration method is migration-sedimentation. However, its yield is relatively small and the technique is therefore normally only limited to ejaculates with a high number of motile spermatozoa. Recently, however, the method was also successfully used to isolate spermatozoa for intracytoplasmic sperm injection (ICSI. Sperm separation methods that yield a higher number of motile spermatozoa are glass wool filtration or density gradient centrifugation with different media. Since Percoll® as a density medium was removed from the market in 1996 for clinical use in the human because of its risk of contamination with endotoxins, other media like IxaPrep®, Nycodenz, SilSelect®, PureSperm® or Isolate® were developed in order to replace Percoll®. Today, an array of different methods is available and the selection depends on the quality of the ejaculates, which also includes production of reactive oxygen species (ROS by spermatozoa and leukocytes. Ejaculates with ROS production should not be separated by means of conventional swim-up, as this can severely damage the spermatozoa. In order to protect the male germ cells from the influence of ROS and to stimulate

  8. Leukocytes and oxidative stress: dilemma for sperm function and male fertility

    Spermatozoa are constantly exposed to the interphase between oxidation through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions as being the only cells with such high polarization and exerting their functions outside the body, even in a different individual, the female genital tract, the membranes of these cells are chemically composed of an extraordinary high amount of polyunsaturated fatty acids. This in turn, renders them very susceptible to oxidative stress, which is defined as an imbalance between oxidation and reduction towards the oxidative status. As a result, ROS deriving from both leukocytes and the male germ cells themselves cause a process called 'lipid peroxidation' and other damages to the sperm cell. On the other hand, a certain limited amount of ROS is essential in order to trigger vital physiological reactions in cells, including capacitation or the acrosome reaction in sperm. The treatment of patients with antioxidants to compensate the oxidative status caused by oxidative stress is highly debated as uncontrolled antioxidative treatment might derail the system towards the reduced status, which is also unphysiological and can even induce cancer. This paradox is called the 'antioxidant paradox'.Therefore, a proper andrological diagnostic work-up, including the evaluation of ROS levels and the antioxidant capacity of the semen,has to be carried out beforehand, aimed at keeping the fine balance between oxidation and scavenging of vital amounts of ROS.

    It is of increasing importance to assess the relationship between impaired male fertility and environmental factors. Due to the complex development and regulation of spermatogenesis, a variety of sites may be affected by exogenous noxae such as coffee, tobacco, alcohol, pharmaceuticals, professional agents, environmental chemicals and also physical factors. However, reliable findings in humans are only available for a few noxae. Unfortunately, results from animal experimental studies cannot be simply transferred. In the andrological practice, detailed history taking is of utmost importance for early recognition of possible exposure risks. Thorough analysis of the ejaculate is a prerequisite for detection and differentiation especially of disturbed spermatogenesis. Under aspects of occupational and environmental medicine, systematic search for data according to standardized criteria in exposed and unexposed men is imperative to find out potential reproductive toxins.

Gesicherte Erkenntnisse liegen jedoch beim Menschen nur fuer wenige Noxen vor. Leider lassen sich tierexperimentelle Befunde nur begrenzt uebertragen. In der andrologischen Praxis kommt einer ausfuehrlichen Anamnese ein wichtiger Stellenwert zu, um moegliche Expositionsrisiken fruehzeitig erfassen zu koennen. Detaillierte Ejakulatanalysen sind hier zur Erfassung und Differenzierung, insbesonders von Spermatogenesestoerungen, unerlaesslich. Unter arbeits- und umweltmedizinischen Gesichtspunkten sind systematische Datenerhebungen nach standardisierten Kriterien bei exponierten und nicht exponierten Maennern unerlaesslich, um

    Increasingly accumulated results from randomized controlled trials and other clinical studies have demonstrated that male circumcision reduces the risks of acquisition and transmission of HIV, HPV, HSV-2, and other sexually transmitted infections, and thus has a potential role in preventing cervical cancer, penile cancer and prostate cancer. The prevalence of male circumcision in China is currently less than 5%. The clinical evaluation studies and randomized controlled trials of the Shang Ring device showed excellent safety profiles, extremely high acceptability, and satisfaction among the participants and service providers in Africa and China. Given the recent recommendations by the World Health Organization and the Joint United Nations Program on HIV/AIDS (UNAIDS), voluntary medical male circumcision should be promoted in China at the national level as an important alternative intervention to reduce reproductive tract infections and prevent both males and females from reproductive tract cancers. More emphasis is required on the studies of the long-term health benefits of male circumcision in uro-andrology.

    Full Text Available Objectives: The aim of our study was to report our experience with patients affected by Erectile Dysfunction (ED and undergoing penile prosthetic implantation (PPI in a single center by a single surgeon. Material and Methods: We retrospectively evaluated the clinical outcome of 500 patients (mean age: 51.5 years, range: 20-86 years affected by ED and referred to our private andrological center from January 1984 to December 2013 who underwent penile prosthesis implantation, including the reported level of patient satisfaction. Results: 182 silicone, 180 malleable, 18 monocomponent hydraulic and 120 multicomponents hydraulic prostheses were implanted by the same experienced surgeon. All patients were hospitalized for the procedure. All patients were evaluated immediately, 1 month (496 patients and, for the great majority, every year after implantation. One hundred twenty five patients were lost to follow-up. Twenty two patients underwent revision surgery for complications in the postoperative period. The most serious postoperative complications were mechanical problems (45 patients, 9.0% and infection (15 patients, 3%. Forty two (8.4% prostheses were explanted. Overall, 80% (400/500 of patients were able to have sexual intercourse and were fully satisfied with the results. Conclusions: In our experience prosthetic surgery should be considered a good solution for men affected by ED and not responsive to other therapeutic solutions. Prosthetic surgery can be performed not only in large public hospitals but also in smaller private facilities.

    Background Recent years, morbidity of chronic prostatis is increasing in Mongolia. Most common cause of the chronic prostatis is Non-Gonococcal Urethritis (NGU) such as chlamydia trachomatis, mycoplasma hominis, mycoplasma genitalium, ureaplasma urealyticum and ureaplasma parvum or mixed infections. Purpose The purpose of the study was to research possible relationships between signs or symptoms of the chronic prostatitis and its cause. Method A total of 466 males who have possible signs of chronic prostatitis were enrolled in the study. All patients were checked for urinalysis and expressed prostate secretion (EPS) and Polymerase Chain Reaction (PCR) of EPS detection for neisser a gonorrhea, chlamydia trachomatis, mycoplasma hominis, mycoplasma genitalium, ureaplasma urealyticum and ureaplasma parvum at an outpatient center of andrology office, Ulaanbaatar, Mongolia. Results Two hundred and eighty three of all participants have positive PCR results. Mean age of in our study was 33.1±8 years. U. realyticum was the most common (48.6%), followed by M. hominis and C. trachomatis mixed infection. In Mach, April and August were highest episodes of morbidity were registered 16.2%, 11.69% and 10.71%. Chronic pelvic pain syndrome and lower urinary tract symptoms were the most common complaints of main reason to visit outpatient clinic. Conclusions U. urealyticum was most common infection detected by PCR analyses among men who have chronic prostatitis, who have chronic pelvic pain syndrome. Further research is needed to determine if there are associations between signs or symptoms and cause of the chronic prostatis.

    Flow cytometry is now a recognized methodology within animal spermatology, and has moved from being a research tool to become routine in the assessment of animal semen destined to breeding. The availability of 'bench-top' flow cytometers and of newer and versatile markers for cell structure and function had allowed the instrumentation to measure more sperm parameters, from viability to reactiveness when exposed to exogenous stimuli, and to increase our capabilities to sort spermatozoa for potential fertilizing capacity, or chromosomal sex. The present review summarizes the state of the art regarding flow cytometry applied to animal andrology, albeit keeping an open comparative intent. It critically evaluates the present and future capabilities of flow cytometry for the diagnostics of potential fertility and for the development of current reproductive technologies such as sperm freezing, sperm selection and sperm sorting. The flow cytometry methods will probably further revolutionize our understanding of the sperm physiology and their functionality, and will undoubtedly extend its application in isolating many uncharacterized features of spermatozoa. However, continuous follow-up of the methods is a necessity owing to technical developments and the complexity of mapping spermatozoa.

    Decades of human semen studies have yielded compelling evidence that sperm can be used to access reproductive potential and diagnose pathology. With these studies as background, the small number of detailed semen studies of men exposed to physical and chemical agents point with optimism to the application of human semen assays as efficient, effective means to monitor for reproductive hazards in the workplace. Sperm are the most accessible of human gonadal tissue and provide a means of monitoring exposure induced changes in the human testes, changes which may result in infertility and increased frequencies of genetically abnormal gametes. The focus on semen has precipitated the development of new sperm bioassays which use older conventional andrological methods (i.e., sperm counts, motility, and morphology) as well as recently developed high speed flow and scanning methods for automated cytological analyses. The status of these sperm assays for workplace surveillance is reviewed, procedures are suggested with examples of use, and their effectiveness is evaluated. The available mouse models of induced semen changes are briefly described and the importance of these models for evaluating the genetic implications of findings in human semen is discussed.

Beside the traditional training forms – and built to them - there was a need for implementing a new distant teaching system, which provides a comprehensive distance education, resting on multimedia foundations, for the all colleagues of Central Agricultural Office working in different parts of the country and in different professional areas. The aim of our publication is to show how we introduced the e-Learning education within the distance education framework system of CAO, and to share our experiences obtained during the pilot training. The five courses of pilot training turned out a success: the results of examinations (the mean values: 84-91% and evaluations of questionnaires filled out by more than 200 colleagues taking part in training proved the entitlement of e-Learning education in CAO. However this method needs additional refinements in order to adapt to the specific requirements of andrology.

    In a basic study at the Andrology Unit, Department of Clinical and Molecular Sciences, Polytechnic University of Marche, Ancona, Italy, we evaluated the pattern of mRNA endothelial nitric oxide synthase (eNOS) expression in human blood leucocytes isolated from normozoospermic fertile and asthenozoospermic infertile men to elucidate any pathogenic involvement in sperm cell motility. Forty infertile men with idiopathic asthenozoospermia and 45 normozoospermic fertile donors, age-matched, were included. Semen parameters were evaluated, and expression analysis of mRNA was performed in human leucocytes using reverse transcription polymerase chain reaction. Sperm volume, count, motility and morphology were determined, and eNOS expression and Western blotting analyses were performed. A positive correlation was observed between the concentrations of NO and the percentage of immotile spermatozoa. The mRNA of eNOS was more expressed in peripheral blood leucocytes isolated from asthenozoospermic infertile men versus those of fertile normozoospermic men (7.46 ± 0.38 versus 7.06 ± 0.56, P = 0.0355). A significant up-regulation of eNOS gene in peripheral blood leucocytes was 1.52-fold higher than that of fertile donors. It is concluded that eNOS expression and activity are enhanced in blood leucocytes in men with idiopathic asthenozoospermia.

    Full Text Available Context: Lifestyle factors, like alcohol intake and cigarette smoking, have been reported to affect male fertility. Aims: To find out the specific impact of alcohol and smoking on semen quality of male partners of couples seeking treatment for primary infertility. Materials and Methods: From the semen samples analyzed in our andrology laboratory, results of 100 alcoholics and 100 cigarette smoker males were studied following WHO guidelines and compared with 100 strict nonalcoholic and nonsmoker males for presence of asthenozoospermia, oligozoospermia and teratozoospermia. Statistical Analysis: Data was analyzed by F- test using Microsoft Office Excel 2003. Results: Only 12% alcoholics and six per cent smokers showed normozoospermia compared to 37 % nonalcoholic nonsmoker males. Teratozoospermia, followed by oligozoospermia dominated alcoholics. Overall impact of asthenozoospermia and teratozoospermia, but not of oligozoospermia, was observed in smokers. Light smokers predominantly showed asthenozoospermia. Heavy alcoholics and smokers showed asthenozoospermia, teratozoospermia as well as oligozoospermia. Conclusions: Asthenozoospermia, the most common semen variable in our study, can be an early indicator of reduction in quality of semen. Alcohol abuse apparently targets sperm morphology and sperm production. Smoke-induced toxins primarily hamper sperm motility and seminal fluid quality. Progressive deterioration in semen quality is related to increasing quantity of alcohol intake and cigarettes smoked.

Both poor water solubility and drug permeability have hindered the percutaneous absorption of silymarin. Formulation of silymarin into pluronic-lecithin organogel (PLO basis for topical skin delivery is the main aim of this work. Six different PLO formulations were prepared containing various pluronic to lecithin ratios using two cosolvent systems of ethyl alcohol and dimethyl sulfoxide. Formulation 2 (20% pluronic and 3% lecithin was found to be the optimal base for topical delivery of silymarin as it showed optimum pH, viscosity, drug content, and satisfactory in vitro silymarin permeation. The silymarin PLO formulation significantly relieved inflammatory symptoms of AD such as redness, swelling, and inflammation. These findings warrant the ability for application of these novel silymarin PLO formulations as a novel treatment for AD.

Therefore, between September 2009 and September 2011, 1801 outpatients at andrology clinics were enrolled and consented to participate in our survey by completed a verbal questionnaire. It included the following: (1 demographic data (e.g., age, body mass index, (2 PE duration, medical history, and sexual history, (3 self-estimated intravaginal ejaculatory latency times, (4 the Zung Self-rating Depression Scale (SDS, and (5 the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI and (6 the International Index of Erectile Function (IIEF-5. The results showed that a total of 1,206 patients were diagnosed with PE. The prevalence rate of depression in these PE patients was 26.78%. Depression was associated with PE duration, NIH-CPSI score, and IIEF-5 score. Risk factors for depression specifically included PE durations for 13–24, 25–60, or ≥61 months, CPSI scores of 15–30 or ≥31, and IIEF-5 scores <22. These findings suggested that several associated factors (PE duration, CPSI scores, and IIEF-5 scores were the risk factors of depression in men with PE.

    To the best of our knowledge, no psychometric tools have been specifically developed to measure if premature ejaculation (PE) is related to low sexual pleasure in terms of perception of orgasmic intensity. Hence, the aim of this study was to evaluate if men with PE suffer from a low perception of orgasmic intensity using a new tool, the 'Orgasmometer', to quantitatively measure the intensity of orgasmic pleasure. Among 329 subjects attending our andrological unit for suspected PE, 257 men fulfilled the inclusion criteria. Of these, 156 (60.7%; 156/257) were affected by PE (PE group) and 101 (39.3%; 101/257) did not have any sexual dysfunction (Control group). Men were requested to fill out the Premature Ejaculation Diagnostic Tool (PEDT) and the Orgasmometer, a new visual tool recording orgasm intensity on a Likert scale. Interestingly, MANCOVA analysis revealed a statistically significant difference between the two groups (p = 0.044) in the subjective perception of orgasm intensity with the PE group scoring lower on the Orgasmometer (mean 5.8; 95% CI 5.191-6.409) than the Control group (mean 7.95; 95% CI 7.033-8.87). In addition, multiple linear regression revealed an inverse correlation between the PEDT and the Orgasmometer scores (p premature ejaculation perceived significantly lower orgasmic intensity than sexually healthy men. The Orgasmometer is an easy-to-perform, user-friendly tool for measuring orgasmic intensity.

    In azoospermic men with congenital bilateral absence of the vas deferens (CBAVD), it is not known whether the outcomes of intracytoplasmic sperm injection (ICSI) depend on the quality of testicular spermatogenesis (as determined histopathologically). We retrospectively studied the impact of spermatogenesis quality on ICSI outcomes in 108 azoospermic men with CBAVD consulting in a university hospital's department of andrology and reproductive biology. As part of an ICSI program, sperm samples were obtained from the epididymis [by microsurgical epididymal sperm aspiration (MESA); n = 47] or the testis [by testicular sperm extraction (TESE); n = 14] or both (MESA + TESE, n = 47). In the TESE group (i.e., TESE-only and MESA + TESE), spermatogenesis was normal in 21 of the 108 men (19.4%) and hypospermatogenesis occurred in 33 (30.5%). The fertilization rate was significantly lower in the hypospermatogenic group than in the normospermatogenesis group (65.6 and 72.9%, respectively; p = 0.02); this was also true for the embryo cleavage rate (88.6 and 92.1%, respectively; p = 0.007), and the proportion of embryos with fewer than 30% of enucleate fragments (79.5 and 86.9%, respectively; p = 0.02). Our study results showed that impaired spermatogenesis had a negative impact on certain early-stage biological outcomes of ICSI. In CBAVD, male factors are likely to exert a harmful effect on the early stages of embryo development.

    Full Text Available Abstract Background We present a case of primary infertility related to extreme cervical stenosis, a subset of cervical factor infertility which accounts for approximately 5% of all clinical infertility referrals. Case presentation A 37 year-old nulligravida was successfully treated with ovulation induction via recombinant follicle stimulating hormone (FSH and direct intraperitoneal insemination (IPI. Anticipating controlled ovarian hyperstimulation with in vitro fertilization/embryo transfer (IVF, the patient underwent hysteroscopy and cervical recanalization, but safe intrauterine access was not possible due to severe proximal cervical stricture. Hysterosalpingogram established bilateral tubal patency and confirmed an irregular cervical contour. Since the cervical canal could not be traversed, neither standard intrauterine insemination nor transcervical embryo transfer could be offered. Prepared spermatozoa were therefore placed intraperitoneally at both tubal fimbria under real-time transvaginal sonographic guidance using a 17 gage single-lumen IVF needle. Supplementary progesterone was administered as 200 mg/d lozenge (troche plus 200 mg/d rectal suppository, maintained from the day following IPI to the 8th gestational week. A singleton intrauterine pregnancy was achieved after the second ovulation induction attempt. Conclusions In this report, we outline the relevance of cervical factor infertility to reproductive medicine practice. Additionally, our andrology evaluation, ovulation induction approach, spermatozoa preparation, and insemination technique in such cases are described.

    Despite controversy regarding the clinical value of semen analysis,male fertility investigation still relies on a standardized analysis of the semen parameters.This is especially true for infertility clinics in both developing and developed countries.Other optional tests or sophisticated technologies have not been widely applied.The current review addresses important changes in the analysis of semen as described in the new World Health Organization (WHO) manual for semen analysis.The most important change in the manual is the use of evidence-based publications as references to determine cutoff values for normality.Apart from the above mentioned changes,the initial evaluation and handling methods remain,in most instances,the same as in previous editions.Furthermore,the review evaluates the importance of quality control in andrology with emphasis on the evaluation of sperm morphology.WHO sperm morphology training programmes for Sub-Saharan countries were initiated at Tygerberg Hospital in 1995.1he external quality control programme has ensured that the majority of participants have maintained their morphological reading skills acquired during initial training.This review reports on current sperm functional tests,such as the induced acrosome reaction,and sperm-zona pellucida binding assays,as well as the impact of sperm qualitv in terms of DNA integritv,and the relationship of sperm function tests to sperm morphologv.

    A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA area pre- and post-Hurricane Katrina. We retrospectively evaluated semen analyses data (n = 3452) of 1855 patients who attended the Tulane University Andrology/Fertility Clinic between 1999 and 2013. The study inclusion criteria were men whose semen analyses showed ≥ 1.5 ml volume; ≥15 million ml -1 sperm concentration; ≥39 million total sperm count; ≥40% motility; >30% morphology, with an abstinence interval of 2-7 days. After the inclusion criteria applied to the population, 367 normospermic patients were included in the study. Descriptive statistics and group-based analyses were performed to interpret the differences between the pre-Katrina (Group 1, 1999-2005) and the post-Katrina (Group 2, 2006-2013) populations. There were significant differences in motility, morphology, number of white blood cell, immature germ cell count, pH and presence of sperm agglutination, but surprisingly there were no significant differences in sperm count between the two populations. This long-term comparative analysis further documents that a major natural disaster with its accompanied environmental issues can influence certain semen parameters (e.g., motility and morphology) and, by extension, fertility potential of the population of such areas.

    Full Text Available Abstract Background In male patients suffering from chronic pain, opioid administration induces severe hypogonadism, leading to impaired physical and psychological conditions such as fatigue, anaemia and depression. Hormone replacement therapy is rarely considered for these hypogonadic patients, notwithstanding the various pharmacological solutions available. Methods To treat hypogonadism and to evaluate the consequent endocrine, physical and psychological changes in male chronic pain patients treated with morphine (epidural route, we tested the administration of testosterone via a gel formulation for one year. Hormonal (total testosterone, estradiol, free testosterone, DHT, cortisol, pain (VAS and other pain questionnaires, andrological (Ageing Males' Symptoms Scale - AMS and psychological (POMS, CES-D and SF-36 parameters were evaluated at baseline (T0 and after 3, 6 and 12 months (T3, T6, T12 respectively. Results The daily administration of testosterone increased total and free testosterone and DHT at T3, and the levels remained high until T12. Pain rating indexes (QUID progressively improved from T3 to T12 while the other pain parameters (VAS, Area% remained unchanged. The AMS sexual dimension and SF-36 Mental Index displayed a significant improvement over time. Conclusions In conclusion, our results suggest that a constant, long-term supply of testosterone can induce a general improvement of the male chronic pain patient's quality of life, an important clinical aspect of pain management.

    Aim: To determine the limitations of a punched-out orchidometer in practical use, we compared with a scrotal ultrasound (USG). Methods: A total of 281 testes from 142 males were examined using both a punched-out orchidometer and a USG. The volume differential between both methods was calculated and expressed as orchidometer/USG volume (O/U ratio). Distribution of the O/U ratio was determined and subdivided by clinical or pathological diagnosis. The correlations between the O/U ratio and patient age or orchidometer results were assessed. Results:There was a significant linear relationship between the results of orchidometer and USG (r = 0.94, P < 0.0001). The relationship between the O/U ratio and age or testicular volumes showed significant inverse correlations (r = 0.22,P = 0.0002, r = 0.45, P<0.0001, respectively). Klinefelter's syndrome, ipsilateral detorted testes and hypogonadotropic hypogonadism comparatively showed a high O/U ratio. No incidental lesion was detected by USG necessitating treatment. Conclusion: The punched-out orchidometer gives estimates that correlated well with the USG measurements and provides enough information for routine andrological evaluation. We should be aware that the orchidometer often overestimates the testicular volume, especially for the patients with small testis or adolescents.

    Traditionally, the success of a researcher is assessed by the number of publications he or she publishes in peer-reviewed, indexed, high impact journals. This essential yardstick, often referred to as the impact of a specific researcher, is assessed through the use of various metrics. While researchers may be acquainted with such matrices, many do not know how to use them to enhance their careers. In addition to these metrics, a number of other factors should be taken into consideration to objectively evaluate a scientist's profile as a researcher and academician. Moreover, each metric has its own limitations that need to be considered when selecting an appropriate metric for evaluation. This paper provides a broad overview of the wide array of metrics currently in use in academia and research. Popular metrics are discussed and defined, including traditional metrics and article-level metrics, some of which are applied to researchers for a greater understanding of a particular concept, including varicocele that is the thematic area of this Special Issue of Asian Journal of Andrology. We recommend the combined use of quantitative and qualitative evaluation using judiciously selected metrics for a more objective assessment of scholarly output and research impact.

    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.

    Sexual health has been defined as "the state of physical, emotional and social wellbeing related to sexuality. However, there are medical, psychological and social reasons that complicate full sexual health that are frequently not attended to sufficiently. The objective of this guide will be to analyze the factors that impact the sexual health of men and women over 50 and to provide recommendations for the most appropriate diagnostic and therapeutic measures for this age group. A panel of experts from various Spanish scientific societies related to sexual health (Spanish Menopause Society, SMS; Asociación Española de Andrología, Medicina Sexual y Reproductiva, ASESA; Federación Española de Sociedades de Sexología, FESS; and Sociedad Española de Médicos de Atención Primaria SEMERGEN) met to reach a consensus on these issues and to decide the optimal timing and methods based on the best evidence available.

    The objective of this study was to investigate the relations of basic semen parameters and reproductive hormones with different surrogate measures of adiposity: body mass index (BMI), body fat percentage (BF%), waist circumference (WC) and waist-to-height ratio (WHtR). Standard semen analysis was performed and serum levels of reproductive hormones were measured in 260 male partners of pregnant women at a university hospital andrology centres in Estonia. Quartile analysis revealed that all adiposity markers were negatively related to sex hormone-binding globulin and total testosterone levels. After adjustment for covariates a high BF%, WC and WHtR were negatively associated with total sperm count. The BF% was also negatively related to semen volume. These significant changes occurred from a BF% ≥ 23.4%, WC > 98 cm and WHtR > 0.54. Next to these changes the BMI was not related to sperm parameters. This study shows that semen quality is affected by central adiposity and confirms earlier findings that adiposity markedly changes serum sex hormone levels. Further studies are required to find out what is the best body composition marker showing most clearly the relationships between adiposity, semen characteristics and sex hormone levels.

    The aim of this study was to investigate the relations of basic semen parameters and reproductive hormones with alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT). In addition, to examine possible interaction between adiposity, alcohol consumption, and liver tests in relation to male reproductive health, standard semen analysis was performed and serum levels of reproductive hormones and liver tests were measured in 245 male partners of pregnant women at a University Hospital Andrology Centres in Estonia. Quartile analysis revealed that after adjustment for covariates GGT was negatively related to sperm concentration and total sperm count. These significant changes appeared from a GGT >35.5 U/L. Next to these changes ALT was not related to sperm parameters. Both enzymes, GGT and ALT, were not related to reproductive hormones. Alcohol consumption was positively related to GGT and in cases with elevated GGT alcohol use was negatively related to sperm concentration and total sperm count. Alcohol consumption was positively related to body mass index (BMI) and waist circumference (WC). Our findings also confirm results of previous studies that BMI and WC are associated positively with ALT and GGT. According to the study, increased GGT activity might represent a possible connection between adiposity, alcohol consumption, and semen quality.

    Insulin-like factor 3 (INSL3) serum levels were measured in 135 andrologically well-characterized normal men and 85 patients with testicular disorders to investigate how the hormone, which is a major secretory product of human Leydig cells, is related to testosterone (T), LH, and semen quality....... INSL3 was measured by using a newly developed fluorescence immunoassay. Median (2.5-97.5 percentiles) INSL3 serum levels were as follows: normal men (n = 135), 0.99 (0.55-1.73) ng/ml; infertile men (n = 23), 1.11 (0.60-2.07) ng/ml; anorchid men (n = 21), nondetectable (ND); patients with 47, XXY......, Klinefelter syndrome (n = 21), 0.12 (ND-0.78) ng/ml; men with hypogonadotropic hypogonadism and T substitution (n = 11), ND; and men with hypogonadotropic hypogonadism and human chorionic gonadotropin (hCG) treatment (n = 5), 0.36 (0.13-0.73) ng/ml.

    Full Text Available The Internet, which has truly united the developed and developing nations, is an extensive network of inter-linked computers storing immense bytes of information, which can be accessed by anyone transcending all geographi-cal barriers and this has become the ultimate frontier to access information. The Urology and Andrology informa-tion on Internet is exponentially growing. The urologist need not know the intricacies of the hardware and soft-ware but can start right away navigating through this web. We reviewed methods available to take advantage of this network to provide a glimpse to busy urologists to accrue the benefits easily and efficiently rather than to be lost in the information-ocean by surfing individually. By getting connected to Internet, an urologist of any part of the world gains enormous information by interacting with other urologists of the rest of the world. This could be of use to gain knowledge and to offer the best and the most modern treatment to the patient. Internet has revolutionised the scientific publication by virtue of its faster and accurate transmission of manuscripts. We can send manuscripts by this channel and also access journals obviating the lag period inherent in snail mail. The on-line journals have virtually brought the library to the desktop.

    The objective of the study was to obtain information on the concentration and distribution of selenium throughout the human male reproductive tract. Material was removed at autopsy from 41 men who had died suddenly and unexpectedly. Semen samples were also provided from 184 men attending an andrology clinic for fertility investigation and from 32 healthy volunteers. Significant positive correlations in the selenium concentration were demonstrated between the different reproductive organs, the testis having the highest concentrations. No correlation was found between the concentration of selenium in the genital organs and liver, kidney or blood, suggesting that its uptake and/or biochemical activity in the reproductive organs may be controlled by similar mechanisms not shared by the other organs. No significant age-dependent changes could be detected in tissue selenium concentrations. In a group of men under fertility investigation, a significant positive correlation was obtained between seminal plasma concentrations of selenium and concentrations of spermatozoa in the same ejaculate. A significant positive correlation between concentrations of zinc and selenium in the same ejaculates indicated that selenium may arise largely from the prostate gland.

    The authors studied the publications written by the staff of the University Department of Urology in Budapest, Hungary between 1946 and 1956. The collection was contributed on the occasion of Professor Babics's 10-year-long chairmanship. Over a period of 10 years, 214 papers were published by 15 urologists, including 3 books and 3 PhD theses; 16 papers were published in German, 22 in English, 2 in French, and 1 in Italian. The most frequent topic of the papers (26) was basic science (e.g., ureter motility, lymph circulation, intrarenal pressure condition). Other papers dealt with nephrology, artificial kidneys, TURP, and nephron-sparing renal surgery. Some articles examined various types of malignant tumors and benign prostatic hyperplasia, while 17 publications focused on the topic of andrology. Tuberculosis was also discussed by the authors. Despite political isolation, the communist dictatorship, poverty, the lack of health equipment, physicians educated before WWII with their work morality and hard work managed to perform contemporary clinical and basic scientific research.

    Full Text Available Abstract Background Infertility is defined as inability of a couple to conceive naturally after one year of regular unprotected sexual intercourse. It remains a major clinical and social problem, affecting perhaps one couple in six. Evaluation usually starts after 12 months; however it may be indicated earlier. The most common causes of infertility are: male factor such as sperm abnormalities, female factor such as ovulation dysfunction and tubal pathology, combined male and female factors and unexplained infertility. Objectives The aim of this study is to provide the healthcare professionals an evidence-based management protocol for infertile couples away from medical information overload. Methods A comprehensive review where the literature was searched for "Management of infertility and/or infertile couples" at library website of University of Bristol (MetaLib by using a cross-search of different medical databases besides the relevant printed medical journals and periodicals. Guidelines and recommendations were retrieved from the best evidence reviews such as that from the American College of Obstetricians and Gynaecologists (ACOG, American Society for Reproductive Medicine (ASRM, Canadian Fertility and Andrology Society (CFAS, and Royal College of Obstetricians and Gynaecologists (RCOG. Results A simple guide for the clinicians to manage the infertile couples. Conclusions The study deploys a new strategy to translate the research findings and evidence-base recommendations into a simplified focused guide to be applied on routine daily practice. It is an approach to disseminate the recommended medical care for infertile couple to the practicing clinicians.

    ABSTRACT This study describes a new method of microcentrifugation as an improved, viable, cost-effective option to the classical Cytospin apparatus to confirm azoospermia. Azoospermic semen samples were evaluated for cryptozoospermia by a centrifugation method similar to that of World Health Organization guidelines (2010; entire specimen centrifuged at 3000g for 15 min, and aliquots of the pellet examined). Then, if no sperm were detected, the pellet from that procedure was resuspended in culture medium, centrifuged (2000g for 15 min), and the entire pellet spread on a 4 X 6mm area of a slide and stained using the Christmas tree method (Nuclear-Fast solution and picric acid). The entire stained area was examined for the presence or absence of sperm. A total of 148 azoospermic samples (after standard WHO diagnosis) were included in the study and 21 samples (14.2%) were identified as sperm-positive. In all microcentrifugation slides, intact spermatozoa could be easily visualized against a clear background, with no cellular debris. This novel microcentrifugation technique is clearly a simple and effective method, with lower cost, increasing both sensitivity and specificity in confirming the absence or presence of spermatozoa in the ejaculate. It may represent a step forward of prognostic value to be introduced by andrology laboratories in the routine evaluation of patients with azoospermia in the initial semen analysis. PMID:27136479

    About 30% of male infertility cases are idiopathic. Previous studies reported a positive correlation between deep periodontal pockets and sperm sub-motility, which suggests that periodontitis might have a role in idiopathic semen abnormality pathospermia. We evaluated correlations between periodontal infection parameters and the results of sperm analysis of men with idiopathic infertility. In this observational study, semen quality and periodontal status were analyzed for 95 otherwise healthy men attending an andrology unit for sperm analysis. Half the men in the sperm pathology and normozoospermia groups (50.8% and 50%, respectively) had poor periodontal status. Among the 95 participants, 38% had oligozoospermia, 28% had asthenozoospermia, 16% had cryptozoospermia, and 15% were classified as normozoospermic. Sperm pathology category was not associated with frequency of deep periodontal pockets or calculus. Bleeding on probing was significantly lower among men with asthenozoospermia than among those with normozoospermia. Poor periodontal status was not associated with any sperm pathology category or parameter. In contrast with previous findings, the present results indicate that pathospermia and poor semen quality are not associated with periodontal infection in men with idiopathic infertility.

    Exposure to genital heat stress among men of barren couples was evaluated in a prospective study. Five hundred and forty-two consecutive patients referred for andrological examination were asked to complete a specific questionnaire at their first visit. For 449 patients who answered all questions, the individual score values could be calculated by scoring each answer with points. Patients with 'idiopathic' oligoasthenoteratozoospermia had significantly higher score values when compared with men showing normozoospermia (P cryptozoospermia (P < 0.01) or other pathological semen profiles (P < 0.05). These data support the hypothesis that patients with 'idiopathic' oligoasthenoteratozoospermia are more exposed to genital heat stress than normozoospermic men. Moreover, in patients with a varicocele impairment semen quality was associated with significantly higher score values compared with the subgroup of men with normal semen profiles (P < 0.05). In contrast, the score values did not significantly differ between equivalent subgroups of men with a history of a retractile testis. Our observations indicate that the questionnaire used in the present study allows an integrative assessment of genital heat stress, which is superior to single factor analysis. Notably, the group of men with 'idiopathic' oligoasthenoteratozoospermia showed the highest mean score values for 10 of the 18 questions compared with the other groups. Prolonged sitting in a vehicle represented the only single factor with significantly different score values in patients with 'idiopathic' oligoasthenoteratozoospermia and those with normozoospermia (P < 0.05).

    High success rates have been reported for the use of intracytoplasmic sperm injection (ICSI) in alleviating essentially andrological infertility. However, neither the relationship between any of the sperm parameters and the result of ICSI nor the minimal sperm requirements for ICSI have been investigated so far. In this paper, our objective was therefore to study the relationship between three basic sperm parameters (total sperm count, sperm motility and morphology) and the outcome of ICSI by retrospective analyses of fertilization, embryo development and pregnancy rates in 966 micro-injection cycles, performed with ejaculated semen. The results showed that there was no important influence from either the type or the extent of sperm impairment on the outcome of ICSI. Even in the most extreme cases of male-factor infertility, where cryptozoospermia or total astheno- or total teratozoospermia was diagnosed in the initial semen sample, high fertilization and pregnancy rates were obtained by ICSI. Only one condition had a strongly negative influence on the result of ICSI: where an immotile (presumably dead) spermatozoon was injected into the oocyte. Thus the only ultimate criterion for successful ICSI is the presence of at least one living spermatozoon per oocyte in the pellet of the treated semen sample used for micro-injection.

    The main aim of the current research was to discover the personal values that may support men's prostate cancer screening decisions in the future. We asked for participants' past behavior and future behavioral intentions, and also considered their real-life behavior. The sample consisted of 371 men, of which 93 were first-time patients at the Andrology Unit. The results show that Security value was related to past participation, while Achievement, Stimulation, and Traditions counteracted this. Present prostate-testing behavior was related only to higher Security values. Predictors of future behavioral intentions were Security, Self-direction, and Benevolence, which described 21% of the total variability. Considering informed decision-making processes, our results suggest that men who hold Security, Self-direction, and Benevolence values are more likely to participate in office-based initial screening. The study indicates the need to offer office-based initial screening to those age-eligible men whose values do not support participation.

    For many years, andrologists have sought ways of assessing sperm fertility, especially of new sires entering the breeding chain. As knowledge of the complex processes that enable sperm to fertilize eggs has increased, it has become clearer that quantitative estimation of the fertilizing potential of a sire or an ejaculate is actually unlikely ever to be fully realized. Here, we propose that a better approach is to identify substandard males and semen samples. During the past decades, the use of fluorescence technologies in biomedical science has burgeoned, with the development of very powerful instrumentation such as confocal microscopy and flow cytometers of ever-increasing capabilities together with a vast range of fluorochromes and fluorochrome conjugates. This technology has been applied to andrology but thus far in only a relatively simple way. In this review, we offer strategies for assessing a large range of sperm functions thought to be related to fertilizing ability over a temporal window rather than at a single time point. From such an assessment profile, sperm samples that over-respond or do not respond sufficiently could be identified, termed dysfunctional and rejected. We outline the rationales behind such tests, present information on new potentially useful fluorochromes and current flow cytometer models that would be suitable for the multicolour multifunctional tests we propose, and we offer suggestions as to how andrologists might design such multicolour tests for themselves.

    Full Text Available Background: caffeine, a methylxanthine derivate, appears to inhibit phosphodiesterase, thereby inhibiting the break down of cAMP and increasing its concentration inside cell. This study aims to assess the effect of caffeine addition in Earles’s Balanced Salt Solution (EBSS on the increase in membrane integrity and acrosome reaction of spermatozoa using swim up method. Methods: This study was carried out at the Clinic of Sexology and Andrology, Sanglah Public Hospital at Denpasar Bali-Indonesia. This study was an experimental study using the design of pre and post test paired control group design. The samples were sperm specimens of eighteen infertile couple male or volunteers who were infertile with age ranged between 20-40 years old. The samples   were divided into two groups: treatment group (caffeine + EBSS and control group (EBSS. The data were analysed statistically by normality test (Kolmogorov - Smirnov Goodness of Fit Test, Homogeneity test, and Paired Student’s t test.  Results: The results showed that the caffeine addition in EBSS medium could increase significantly (p<0.05.  The integrity of the sperm membrane obtained were from 81.30 % to 86.60 % and acrosomal reaction from 82.60% to 89.60% evaluated by hypo-osmotic swelling test (HOS. The conclusion of this study is that addition of caffeine in EBSS medium increases significantly membrane integrity and acrosomal reaction of the human sperm.

    Full Text Available Sperm traits of 243 young bulls from Caracu (n=62, Gir (n=23, Guzerá (n=59 and Nellore (n=99 breeds, with 20-25 months of age, from the Breeding Program of Estação Experimental de Zootecnia de Sertãozinho, were analyzed. On the day of breeding soundness evaluation animals were weighed, the scrotal circumference was measured and the semen was collected by electroejaculation. The sperm motility, vigor and morphology were assessed and the animals were classified according to the andrological classification by points (CAP. No difference was observed among breeds for any seminal trait evaluated, although Nelore presented lower scrotal circumference average than the other breeds. When the animals were classified by body weight, it was observed that the heavier animals presented greater scrotal circumference, better seminal characteristics and, consequently, greater percentage of these animals were considered sexually mature comparing with the other body weight groups. It was concluded that the animals selected for post-weaning and reared on pasture from the taurine adapted breed Caracu and from the zebu breeds Gir, Guzerá and Nelore have proved able to reproduction at 23.2, 23.4, 22.7 and 22.8 months, respectively, corresponding to age which reached an average weight of 452, 422, 470 and 467 kg respectively.

    Full Text Available A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA area pre- and post-Hurricane Katrina. We retrospectively evaluated semen analyses data (n = 3452 of 1855 patients who attended the Tulane University Andrology/Fertility Clinic between 1999 and 2013. The study inclusion criteria were men whose semen analyses showed ≥ 1.5 ml volume; ≥15 million ml -1 sperm concentration; ≥39 million total sperm count; ≥40% motility; >30% morphology, with an abstinence interval of 2-7 days. After the inclusion criteria applied to the population, 367 normospermic patients were included in the study. Descriptive statistics and group-based analyses were performed to interpret the differences between the pre-Katrina (Group 1, 1999-2005 and the post-Katrina (Group 2, 2006-2013 populations. There were significant differences in motility, morphology, number of white blood cell, immature germ cell count, pH and presence of sperm agglutination, but surprisingly there were no significant differences in sperm count between the two populations. This long-term comparative analysis further documents that a major natural disaster with its accompanied environmental issues can influence certain semen parameters (e.g., motility and morphology and, by extension, fertility potential of the population of such areas.

    Semen analysis does not have an absolute predictive value on fertility, however it is a reflection of male fertility potential, which is related to its spermatozoa quality and other semen variables. Great variability in human semen parameters has been demonstrated within a single individual, an observation that could explain why a male with low semen quality can successfully fertilize an egg. Although conventional semen analysis, such as sperm concentration, motility and morphology, provide important information about the clinical status of male fertility, new procedures to predict the sperm functional capability have been developed in the last decade, such as analysis of nuclear DNA integrity, which have improved considerably the clinical diagnosis of male infertility, and increased the knowledge about spermatozoa function. DNA fragmentation consist in interruptions, both in single and double DNA strains, that frequently occur in sperm samples from infertile patients. We have conducted a clinical study in semen samples from patients who have attended the Andrology laboratory of the University of Los Andes, between March 2007 and March 2009. The aim of this study was to compare sperm DNA integrity, analyzed by flow cytometry, with traditional semen parameters. Our results show remarkable correlations between conventional human semen variables and sperm chromatin integrity, contributing to asses an integral evaluation of sperm quality allowing the analysis of its fertilizing potential in clinical studies.

    Aim: To analyse the possible effect of seasonal variation on semen parameters. Methods: The participants consisted of 1688 men attending the andrology laboratory between 1991 and 1997 for reduced fertility in the couple. Semen analysis was performed according to the WHO manual. The 84 individual months of the study period were each assigned to one of the three groups according to the average monthly outside temperature; Group A (temperature 13.3 ℃). Results: When comparing the different sperm parameters, the morphology was significantly better in Group C. However, when the smokers were analysed separately, this difference disappeared and significant seasonal variations were found in sperm density, total sperm count, motility and total motile sperm; they were deteriorated in the warmer season. In non-smokers, no such negative effect of increased temperature was observed. Conclusion: Sperm quality is influenced by seasonal factors.Increased environmental temperature, (maybe also light exposure) has an additional negative effect on the spermatogenesis in smokers, leading to reduced sperm quality in men with borderline fertility.

    Full Text Available The advent of innovative techniques for addressing infertility has made for exciting times in the arena of andrology. The success of microTESE for retrieving sperm has enabled azoospermic men to have the opportunity to father biological children when it was previously impossible. The ability to offer a variety of assisted reproductive techniques that includes intracytoplasmic sperm injection has opened the door for couples with male factor infertility who were otherwise untreatable. With the multitude of options available to infertile couples, however, comes an unsurprising degree of controversy regarding what treatments should be offered and when. Complicating the picture is the question of if and when varicocele repair should be undertaken, and the financial implications of the treatment decisions that are made. The infertile couple with varicocele warrants careful consideration. The overall efficacy of varicocele repair as well as cost-effectiveness of repair compared to immediate microTESE in azoospermic men and assisted reproductive technology in men with suboptimal semen parameters will be reviewed.

    In September 1994, the Kennedy Institute of Ethics Journal published a special issue on the ethics of embryo splitting or "cloning," which included papers originally prepared for a workshop on embryo splitting sponsored by the National Advisory Board on Ethics in Reproduction (NABER) and NABER's report, Human Cloning through Embryo Splitting. The impetus for the project was embryo-splitting research conducted by Drs. Jerry L. Hall, Robert J. Stillman, and others, at George Washington University and presented in October 1993 at a joint meeting of the American Fertility Society and the Canadian Fertility and Andrology Society. Media coverage at the time reported that the research had been approved by the university's formal review committees. However, it came to light in December 1994 that the researchers had not obtained approval from the university's institutional review board prior to conducting the research. Following a university investigation, the researchers were disciplined and instructed to destroy their data. The university also voluntarily forwarded the records of the incident to the Office for Protection from Research Risks at the National Institutes of Health. Dr. Hall resigned from George Washington University in September 1994. In the following postscript to her article on the ethics of embryo splitting (KIEJ, September 1994), Ruth Macklin discusses these events. The letters and memoranda that she cites were obtained from NIH through the Freedom of Information Act.

Risk factors primarily associated with Peyronie's disease include Dupuytren's contracture, penile trauma, and family history. A variety of treatment strategies have been utilized, including oral and topical agents, electromotive drug administration, intralesional injections, extracorporeal shockwave therapy, penile traction, and surgery. However, most of these strategies are ineffective, with surgery being the only definitive treatment. Collagenase clostridium histolyticum is a newly US Food and Drug Administration-approved agent for intralesional injection. It is thought to downregulate many of the disease-related genes, cytokines, and growth factors and degrade collagen fibers. It also suppresses cell attachment, spreading, and proliferation. Collagenase clostridium histolyticum has been clinically proven to be a safe and effective therapeutic option, demonstrating decreases in penile curvature and plaque consistency, as well as increases in patient satisfaction. During clinical evaluation, the Peyronie's Disease Questionnaire was validated as an effective tool for assessing treatment outcomes.

    To identify meiotic criteria for infertility management in non-obstructive azoospermic men, a prospective and multicentric study was organized in Andrological Departments of Paris (France), Roma (Italy) and Budapest (Hungary). In 117 non-obstructive azoospermic men with normal karyotype and no Y-chromosome microdeletion, histology and meiotic studies on bilateral bipolar testicular biopsies were done. Histologically, 40 patients (34%) presented spermatocyte or spermatid arrest, 39 (33%) hypospermatogenesis whereas no meiotic cell could be observed in the remaining patients (33%). Cytogenetically, meiotic figures could only be obtained from the two first histological groups. Meiotic abnormalities were observed in a total of 44 patients (37.6%) including nine patients (7.7%) with severe class I and class IIB anomalies and 19 patients (16.2%) with class IIC environmentally linked meiotic abnormalities. These results provided essential clues for an accurate clinical management. For patients with no meiotic figures and patients with class I and class IIB anomalies, an hormonal stimulation is illusory and a sperm gift should be directly proposed. An hormonal stimulation should be proposed to all the other patients, either directly or following the treatment of the testicular microenvironment for the patients presenting class IIC anomalies. The genetic risk and possibility of prenatal chromosomal analysis in case of pregnancy should be clearly exposed to all the couples in all the cases where type IIA, III or IV anomalies are present. This therapeutical strategy has been applied to all the patients in our series.

    Aim:To test the hypothesis that season affects the semen quality of swamp buffalo (Bubalus bubalis) bulls used for artificial insemination (AI) under tropical conditions in Thailand, as it does in Bos taurus and Bos indicus. Methods: Clinical and andrological examinations, and monitoring of semen production and quality were carried out on five mature, healthy swamp buffalo AI bulls in Thailand from July 2004 to the end of June 2005. Sperm output, motility, morphology and plasma membrane integrity (PMI) were compared between three seasons of the year (rainy, I.e. July-October; winter, I.e. November-February; and summer, I.e. March-June) with distinct ambient temperature and humidity. Results: All bulls were diagnosed as clinically healthy and with good libido throughout the study. Ejaculate volume, pH, sperm concentration, total sperm number and initial sperm motility did not differ between seasons, whereas PMI and the relative proportion of morphologically normal spermatozoa were highest in summer and lowest in winter (P < 0.05). Buffalo age, week of collection and season influenced sperm morphology (P < 0.05-0.001). Among morphological abnormalities,only proportions of tail defects were affected by season, being highest in the rainy season and lowest in summer (P<0.001). In conclusion, climatic changes did not seem to largely affect semen sperm output or viability. Although the proportions of PMI and tail abnormalities were affected by season, they were always below what is considered unacceptable for AI bull sires. Conclusion: Seasonal changes did not appear to cause deleterious changes in sperm quality in swamp buffalo AI-sires in tropical Thailand.

    Discussions can be seen on the sexually -transmitted diseases related to male homosexuality in the Ming and Qing Dynasty.Based on the conceptions of yin and yang,medical professionals and moralists argued that male homosexuality leads to the intercourse between two yangs,on the top of which the hyperactive yang (kan-gyang)results in diseases.The andrology diseases referred to include turbidity (zhuobing),and malnutrition (gan-bing).The commonly seen diseases related to male homosexuality were vision -impairment,infertility,strength -exhaustion,in which the concept of male homosexual toxin (longyangdu)was particularly prominent.Medical pro-fessionals grounded their pathological reasoning on the basis of moral ideas,by which conclusions were reached prior to their proofs.This is an enlightening illumination of medical idealism.%与男色同性恋相关的疾病在明清时期有所讨论,诸医家及社会道德人士立足于阴阳观念,认为男男性行为是两阳相并,亢阳则诸疾丛至。所言男色男科病包括有浊病、疳病等,由男色引起的普通疾病包括有目损、艰嗣、体虚等,而“龙阳毒”的概念尤其引人瞩目。医家们用道德观念来推断病因,先下结论再找理由,为医学唯心主义提供了一个典型例证。

  8. Profile of men's health in Malaysia: problems and challenges.

    2011-07-01

    Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges.

    Enzo Vicari

    Full Text Available BACKGROUND: Although prostatitis syndrome (PS and irritable bowel syndrome (IBS are common disorders, information on the prevalence of IBS in infertile patients with PS is relatively scanty. Therefore, this study was undertaken to estimate the frequency of PS and IBS and to evaluate the prevalence of the various diagnostic categories of prostatitis. METHODOLOGY/PRINCIPAL FINDINGS: This study enrolled 152 patients with PS, diagnosed by the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI in an andrological setting, and 204 patients with IBS, diagnosed according to the Rome III diagnostic criteria in a gastroenterological setting. The patients with PS were asked to fulfill the Rome III questionnaire for IBS, whereas patients with IBS were asked to complete the NIH-CPSI. The simultaneous presence of PS and IBS was observed in 30.2% and 31.8% of the patients screened by andrologists and gastroenterologists, respectively. Altogether, 111 patients had PS plus IBS (31.2%. They had a total NIH-CPSI and pain subscale scores significantly higher than patients with PS alone. Gastrointestinal symptoms in patients with PS plus IBS were similar to those reported by patients with IBS alone and significantly greater in patients with PS alone. Patients with PS plus IBS had a significantly higher frequency of chronic bacterial prostatitis (category II and lower of non-inflammatory prostatitis (category IIIB, compared to patients with PS alone. The frequency of inflammatory prostatitis (category IIIA resulted similar. CONCLUSIONS/SIGNIFICANCE: Prostatitis syndromes and IBS are frequently associated in patients with PS- or IBS-related symptoms. These patients have an increased prevalence of chronic bacterial and non-inflammatory prostatitis.

    Full Text Available Objectives: The aim of our study is to determine the presence, quality of sexual dysfunction in patients with fibromyalgia syndrome and to compare with normal population. Material and Methods: A total of 55 sexually active women who were admitted to Department of Physical Therapy and Rehabilitation of Antalya Research and Training Hospital and diagnosed with fibromyalgia syndrome according to 1990 and 2010 American College of Rheumatology (ACR criteria. A control group composed of 50 sexually active women who were admitted to our clinic with various musculoskeletal system complaints were also included in the study in order to compare the parameters used for clinical assessment of patients and to determine whether the patients differ from normal population. Patients and controls who met inclusion criteria were applied Female Sexual Function Index (FSFI for assessment of sexual function. This test was developed by Rosen and colleagues in 2000, it is composed of 19 questions and inquires six different dimensions including desire, arousal, lubrication, orgasm, sexual satisfaction and pain. Turkish validation test was done by Turkish Society Of Andrology in 2003, answers are multiplied with a coefficient and each section is evaluated on six scores. Minimum score is 2.4 and maximum is 36 and standardly used for assessment of female sexual dysfunction in Turkey. Results: Subscale and total score of Female Sexual Function Index of Fibromyalgia syndrome patients were found statistically significantly lower than those of control group (p<0.05. Conclusion: Disorders of sexual function or its quality are one of the problems seen in fibromyalgia syndrome patients. It should be noticed that sexual function assessment must be a part of treatment of fibromyalgia syndrome. It is quite difficult to determine the mechanism between sexual dysfunction and fibromyalgia syndrome and new and larger studies are needed to determine this mechanism. (Turkish Journal of

  11. Decreased activity of superoxide dismutase in the seminal plasma of infertile men correlates with increased sperm deoxyribonucleic acid fragmentation during the first hours after sperm donation.

    Sperm DNA fragmentation varies between individuals and is more pronounced with increased patient age and time after sperm donation. The intensification of DNA fragmentation depends on the balance of the oxidoreductive system, which is regulated mainly by two enzymes - superoxide dismutase (SOD) and catalase. The objective of this study was to determine the relationship between sperm DNA fragmentation dynamics, fertility and seminal SOD and catalase activity. The study was conducted in 2013 and 2014 at the Non-Public Health Care Unit 'Ovum Reproduction and Andrology' in Lublin, Lublin, Poland, and covered 218 men aged 25-35 (85 fertile and 133 patients treated for infertility). Percentage of fragmented DNA was measured in a modified chromatin dispersion test at four time points after sperm donation (t = 0, 3, 6, 12 h). SOD and catalase activities were determined spectrophotometrically. We confirmed that the activity of SOD in the seminal plasma of men with reproductive disorders was lower compared with fertile men. Conversely, no significant correlations were found between fertility and catalase activity. Sperm DNA of infertile males was initially more fragmented than fertile male sperm DNA. SOD and catalase activity did not correlate with the degree of DNA fragmentation in fertile men. In men with reproductive disorders, the rate of DNA fragmentation was slow within first 3 h after sperm donation and then increased between 6 and 12 h. In this group of infertile men, those with higher SOD activity had a lower DNA fragmentation index (DFI) after 12 h, and a reduced rate of intensity of fragmentation from 6 to 12 h. Alternatively, higher catalase activity among men treated for infertility was accompanied by higher initial DFI and higher rate of DNA fragmentation from 6 to 12 h. These results highlight the importance of determining a proper time window between sperm donation and procedures of assisted reproductive technology.

    The objective of this study was to elucidate the missense Glu298Asp polymorphism within exon 7 of the endothelial nitric oxide synthase (eNOS) gene in infertile men with asthenozoospermia and its potential role in sperm motility. In this prospective controlled study conducted in our andrology unit, we investigated the frequency of the 894G>T polymorphism (Glu298Asp variant) within exon 7 of the eNOS gene in 70 infertile men and 60 healthy men. Sperm motion kinetics were assessed with computer-assisted semen analysis. The presence of G>T, a single nucleotide polymorphism (SNP) in exon 7 of the eNOS gene (NCBI SNP cluster rs1799983; GenBank accession number NG_011992; protein accession number NP_000594) was determined by allelespecific polymerase chain reaction followed by restriction fragment length polymorphism analysis. Sequencing analysis was used to confirm the specific genotype. The 894G>T eNOS allele (T) was found at a higher frequency in the patients with asthenozoospermia (60% vs 22.5% in the control group; P = .02). The percentage of progressive motile sperm (grade a + b) was lower in the asthenozoospermic infertile men with the homozygous eNOS (TT) genotype than in the wild-type eNOS (GG) (P = .02) and heterozygous eNOS (GT) genotypes (P = .01). However, the percentage of progressive motile sperm (grade a + b) was higher in the wild-type vs mutant eNOS (TT) (P = .03) and heterozygous eNOS (GT) genotypes (P = .04). Our findings suggest that the T allele encoding for aspartic acid of the eNOS (Glu298Asp) gene may contribute to poor sperm motility.

    Full Text Available Wayne JG HellstromChief, Section of Andrology, Department of Urology, Tulane University School of Medicine, New Orleans, LA, USAAbstract: Premature ejaculation (PE is a common problem in men worldwide. It has a significant impact on affected men and their partners in terms of self-esteem, dissatisfaction with their sexual relationships, personal distress, and interpersonal difficulty. Psychological therapies may achieve short-term improvements, but there are limited data on the long-term success of these methods. Oral therapy with long-acting selective serotonin reuptake inhibitors (SSRIs improves intravaginal ejaculatory latency time (IELT, but these agents are designed to be administered daily and may be associated with unwanted sexual side effects and withdrawal symptoms upon abrupt discontinuation. Dapoxetine is a short-acting SSRI that can be taken as needed (prn by men with PE. It has been studied in five separate multicenter, randomized, double-blind, placebo-controlled trials involving more than 6000 men with PE. In four studies that evaluated IELT as an endpoint (N = 4843, dapoxetine 30 and 60 mg prn achieved statistically significant increases in IELT versus placebo. Dapoxetine also showed statistically significant improvements in perceived control over ejaculation, PE-related personal distress, and other patient-reported outcomes in all five trials. Dapoxetine treatment is generally well-tolerated, with low incidences of discontinuation syndrome, sexual dysfunction, and treatment-emergent mood symptoms. The most common adverse events with dapoxetine included nausea, diarrhea, headache, dizziness, and somnolence.Keywords: dapoxetine, discontinuation syndrome, premature ejaculation, selective serotonin reuptake inhibitor

    Full Text Available Digito-rectal examination (DRE of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of finding an enlarged prostate size at DRE in subjects with sexual dysfunction (SD. A consecutive series of 2379 patients was retrospectively studied. The analysis was focused on a subset of subjects (n = 1823; mean age 54.7 ± 11.4 selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome (HR = 1.346 (1.129-1.759; P = 0.030, type 2 diabetes mellitus (HR = 1.489 (1.120-1.980; P = 0.006, increased LDL cholesterol (>100 mg dl−1 ; HR = 1.354 (1.018-1.801; P = 0.037 and increased mean blood pressure (BP values (HR = 1.017 (1.007-1.027 for each mmHg increment; P = 0.001. Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction (ED, as well as with other andrological conditions, such as varicocele and premature ejaculation (PE. PSA levels were significantly higher in subjects with enlarged prostate size when compared to the rest of the sample (HR = 3.318 (2.304; 4.799 for each log unit increment in PSA levels; P < 0.0001. Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical (DRE or biochemical (PSA inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular (CV background of the patient.

    The aim of the study was to evaluate the efficiency, after 1 year, of combined use of psychodynamic psychotherapy integrating virtual reality (VR) for the treatment of erectile dysfunction (ED) and premature ejaculation (PE) in 160 heterosexual males who had neither any prior sexual therapy nor had made use (either before, during or after therapy) of any specific pharmaceuticals for the treatment of primary sexual dysfunction. All subjects had given their informed consent. After a clinical diagnosis in an andrologic center, 50 presumably psychological ED (average age 43.7 years), 60 mixed ED (53.9 years) and 50 primary PE (39 years) who suffered these problems over 6 months were undergoing a cycle of 12 sessions, over a 25-week period, of psychotherapy, integrating an audio CD and helmet with miniature television screens that projected specially designed CD-ROM program on the ontogenetic development of male sexual identity. The clinical follow up was done after 6 and 12 months after the cycle. After one year, the overall partial (two times out of three) and complete positive response rate for psychological ED was 75%, for mixed ED was 47% and for PE was 54%. We considered drop-out cases as only before the 7th session of the treatment cycle, the drop-outs after session 7 and the patients that did not show up for follow-up are counted as negative results. Two patients reported nausea and one, vertigo during the first 15-min virtual reality experience. Considering the particular way that full-immersion virtual reality involves the subject who experiences it, we hypothesized that this methodological approach could speed up the therapeutic process. The evidence that positive results persist over time allows us to hypothesize that certain changes in cerebral function can be possible and that these changes are correlated to favorable sexual performance in the male.

    The incidence of male reproductive failure leading to infertility, whether due to delayed parenthood, environmental issues, genetic factors, drugs, etc., is increasing throughout the world. The diagnosis and prognosis of male subfertility have become a challenge. While the basic semen assessment has been performed for many years, a number of studies question the value of the traditional semen characteristics. This is partly due to inadequate methods and standardization, limited knowledge of technical requirements for quality assurance, and an incomplete understanding of what clinical information a semen assessment can provide. Laboratories currently performing semen and endocrine assessment show great variability. The World Health Organization (WHO) manual for the evaluation of semen has been the core of andrology and fertility evaluation that has helped in further development of this field over many years. These include the physical appearance of the ejaculate, assessments of sperm count, motility, vitality, morphology, and functional aspects of the sperm and semen sample. These tests also include male endocrine profile, biochemical evaluation of the semen, detection of antisperm antibodies in serum, the use of computer-aided sperm analysis (CASA), sperm DNA integrity, and its damage due to oxidative stress. Assisted reproductive techniques (e.g., IVF, ICSI) have shown great success but are too expensive. Further development in this field with newer techniques and extensive training/instructions can improve accuracy and reduce variability, thus maintaining the quality and standards of such an evaluation. There is an urgent need to have standardized training centers and increased awareness in this area of men's health for reproductive success.

    Klinefelter syndrome (47, XXY) is the most frequent genetic cause of male infertility and individuals share the endocrine hallmark of hypergonadotropic hypogonadism. Single-nucleotide polymorphisms located within the FSHB/FSHR gene were recently shown to impact serum follicle-stimulating hormone (FSH) levels and other reproductive parameters in men. The objective of this study was to analyse the effect of FSHB-211G>T (c.-280G>T, rs10835638) as well as FSHR c.2039G>A (rs6166) and FSHR c.-29G>A (rs1394205) on endocrine and reproductive parameters in untreated and testosterone-treated Klinefelter patients. Patients were retrospectively selected from the clientele attending a university-based andrology centre. A total of 309 non-mosaic Klinefelter individuals between 18 and 65 years were included and genotyped for the variants by TaqMan assays. The untreated group comprised 248 men, in which the FSHB -211G>T allele was significantly associated with the reduced serum follicle-stimulating hormone levels (-6.5 U/l per T allele, P=1.3 × 10(-3)). Testosterone treatment (n=150) abolished the observed association. When analysing patients before and under testosterone treatment (n=89), gonadotropin levels were similarly suppressed independently of the FSHB genotype. The FSHR polymorphisms did not exhibit any significant influence in any group, neither on the endocrine nor reproductive parameters. In conclusion, a hypergonadotropic setting such as Klinefelter syndrome does not mask the FSHB -211G>T genotype effects on the follicle-stimulating hormone serum levels. The impact was indeed more pronounced compared with normal or infertile men, whereas gonadotropin suppression under testosterone treatment seems to be independent of the genotype. Thus, the FSHB -211G>T genotype is a key determinant in the regulation of gonadotropins in different reproductive-endocrine pathopyhsiologies.

    Full Text Available Because of unavoidable complications of vasectomy, this study was undertaken to assess the efficacy and safety of male sterilization with a nonobstructive intravas device (IVD implanted into the vas lumen by a mini-surgical method compared with no-scalpel vasectomy (NSV. IVDs were categorized into two types: IVD-B has a tail used for fixing to the vas deferens (fixed wing whereas IVD-A does not. A multicenter prospective randomized controlled clinical trial was conducted in China. The study was comprised of 1459 male volunteers seeking vasectomy who were randomly assigned to the IVD-A (n = 487, IVD-B (n = 485 or NSV (n = 487 groups and underwent operation. Follow-up included visits at the 3 rd -6 th and 12 th postoperative months. The assessments of the subjects involved regular physical examinations (including general and andrological examinations and semen analysis. The subjects' partners also underwent monitoring for pregnancy by monthly interviews regarding menstruation and if necessary, urine tests. There were no significant differences in pregnancy rates (0.65% for IVD-A, 0 for IVD-B and 0.21% for NSV among the three groups (P > 0.05. The cumulative rates of complications at the 12 th postoperative month were zero, 0.9% and 1.7% in the three groups, respectively. In conclusion, IVD male sterilization exhibits a low risk of long-term adverse events and was found to be effective as a male sterilization method, similar to the NSV technique. IVD male sterilization is expected to be a novel contraceptive method.

Traditionally, injectable testosterone esters have been used for treatment, but they generate supranormal testosterone levels shortly after the 2- to 3-weekly injection interval and then testosterone levels decline very rapidly, becoming subnormal in the days before the next injection. The rapid fluctuations in plasma testosterone are subjectively experienced as disagreeable. Testosterone undecanoate is a new injectable testosterone preparation with a considerably better pharmacokinetic profile. After 2 initial injections with a 6-week interval, the following intervals between two injections are almost always 12-weeks, amounting eventually to a total of 4 injections per year. Plasma testosterone levels with this preparation are nearly always in the range of normal men, so are its metabolic products estradiol and dihydrotestosterone. The “roller coaster” effects of traditional parenteral testosterone injections are not apparent. It reverses the effects of hypogonadism on bone and muscle and metabolic parameters and on sexual functions. Its safety profile is excellent due to the continuous normalcy of plasma testosterone levels. No polycythemia has been observed, and no adverse effects on lipid profiles. Prostate safety parameters are well within reference limits. There was no impairment of uroflow. Testosterone undecanoate is a valuable contribution to the treatment options of androgen deficiency.Keywords: testosterone treatment, testosterone undecanoate, pharmacokinetic profile, clinical efficacy, side effects

    The molecular diagnosis of Y-chromosomal microdeletions is a common routine genetic test which is part of the diagnostic workup of azoospermic and severe oligozoospermic men. Since 1999, the European Academy of Andrology (EAA) and the European Molecular Genetics Quality Network (EMQN) have been actively involved in supporting the improvement of the quality of the diagnostic assays by publication of the laboratory guidelines for molecular diagnosis of Y-chromosomal microdeletions and by offering external quality assessment trials. The present revision of the 2004 laboratory guidelines summarizes all the clinical novelties related to the Y chromosome (classic, partial and gene-specific deletions, genotype-phenotype correlations, methodological issues) and provides an update on the results of the quality control programme. These aspects also reflect the consensus of a large group of specialists present at a round table session during the recent Florence-Utah-Symposium on 'Genetics of male infertility' (Florence, 19-21 September, 2013). During the last 10 years the gr/gr deletion has been demonstrated as a significant risk factor for impaired sperm production. However, the screening for this deletion type in the routine diagnostic setting is still a debated issue among experts. The original basic protocol based on two multiplex polymerase chain reactions remains fully valid and appropriate for accurate diagnosis of complete AZF deletions and it requires only a minor modification in populations with a specific Y chromosome background. However, in light of novel data on genotype-phenotype correlations, the extension analysis for the AZFa and AZFb deletions is now routinely recommended. Novel methods and kits with excessively high number of markers do not improve the sensitivity of the test, may even complicate the interpretation of the results and are not recommended. Annual participation in an external quality control programme is strongly encouraged. The 12-year

In deep sedoanalgesia, the minipigs were placed in an extended prone position. Commercially available SNM materials were used (needle, introduction sheath, and quadripolar tined lead electrode. Gross anatomy was displayed by CT, and the nerves were bilaterally identified. The optimal angles to puncture the S3 foramen, the resulting access path, and the site for the skin incision were defined subsequently. The needle puncture and the tined lead placement were followed by successive CT scans/3D-reconstruction images. Once proper CT-guided placement of the needle and electrode was established, response to functional stimuli was intraoperatively checked to verify correct positioning.Results: Successful bilateral tined lead implantation was performed in four out of five minipigs. Implantation was different from the clinical situation because the puncture was done from the contralateral side at a 30° angle to the midline and 60° horizontal angle to ensure both passage through the foramen and nerve access. Surgery time was 50–150 minutes. Stimulation response comprised a twitch of the perianal musculature and tail rotation to the contralateral side.Conclusion: We have established a new, minimally invasive, highly standardized, CT-guided SNM electrode implantation technique. Functional outcomes are clearly defined and reproducible. All procedures can be

    We aimed to investigate the role of thioredoxin reductase (TR) and inducible heat shock protein 70 (iHsp70) and their relationship with sperm quality in varicocele (VAR) patients.Semen samples were obtained from 16 subfertile men diagnosed as VAR and 10 fertile men who applied to the Andrology Laboratory of Istanbul Medical Faculty of Istanbul University.The sperm TR and iHsp 70 expression levels were determined using Western blot analysis.The TR activity of the sperm was assayed spectrophometrically.The sperm quality was evaluated both by conventional sperm analysis and by a terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) technique that assayed DNA-fragmented spermatozoa in semen samples.The percentage of TUNEL-positive spermatozoa in the VAR group (16.3%±5.6%) was higher than that in the fertile group (5.5%± 1.9%).Significant inverse correlations were detected between the percentage of TUNEL-positive cells and both the concentration (r=-0.609; P=0.001) and motility (r=-0.550;P=0.004) of spermatozoa.Both the TR expression and activity were increased significantly in the VAR group (U=22.0; P=0.001 and U=33.5; P=0.012,respectively)as analyzed usingthe Mann-Whitney UWilcoxon rank sum Wtest.Furthermore,significant positive correlations were found between TR expression and activity (r=0.406; P=0.040) and between TR expression and the percentage of TUNEL-positive cells (r=0.665; P=0.001).Sperm iHsp70 expression did not differ between the VAR and fertile groups.In conclusion,increased sperm TR expression might be a defense mechanism against apoptosis in the spermatozoa of men with VAR.

    Full Text Available Introduction: Penile implant patients are required to remain in the hospital after the operation for monitoring, antibiotic and analgesia administration. Cost containment, however, has resulted in the increased use of ambulatory surgery settings for many surgical procedures. Few studies have studied the feasibility of performing penile prosthesis insertion in an outpatient setting. The results are controversial and nowadays, in the most of centers that deal with prosthetic surgery, patients are still hospitalized. Aim: The aim of our investigation was to compare the feasibility of the performance as well as the complication profiles of penile implant surgery performed in an in-patient and an outpatient setting at a single center by a single surgeon. Methods: From January 2009 to June 2014, 50 patients of the same uro-andrological unit underwent penile prosthesis implantation performed by a single surgeon (N.M.. Twenty implantations were performed in an ambulatory day surgery setting. Main outcome measures: Effectiveness and costs of outpatient setting versus the in-patient setting of the penile prosthesis surgery. Results: There were some differences between the two groups in the intra-operative parameters, such as, operating time. Time lost from work was similar in both groups approximating 14 days. The mean number of analgesic pills ingested by the patients post-operatively was similar in both groups, averaging just under 25 pills per patient. There weren’t post-operative complications in the outpatient group. Cost were 17% less in outpatient clinic. Conclusions: The outpatient setting for this surgery is safe and effective even in patients with comorbidities or in case of secondary procedures. Costs are reduced by 17%.

The aim of this study was to evaluate the prevalence of most common mutations and intron 8 5T (IVS8-5T polymorphism of CFTR gene in Italian: a azoospermic males; b non azoospermic subjects, male partners of infertile couples enrolled in assisted reproductive technology (ART programs. Material and methods. We studied 242 subjects attending our Andrology Unit (44 azoospermic subjects and 198 non azoospermic subjects, male partners of infertile couples enrolled in ART programs. Semen analysis, molecular analysis for CFTR gene mutations and genomic variant of IVS8-5T polymorphic tract, karyotype and chromosome Y microdeletions, hormonal profile (LH, FSH, Testosterone and seminal biochemical markers (fructose, citric acid and L-carnitine were carried out. Results. The prevalence of the common CFTR mutations and/or the IVS8-5T polymorphism was 12.9% (4/31 cases in secretory azoospermia, while in obstructive azoospermia was 84.6% (11/13 cases; in these, the most frequent mutations were the F508del, R117H and W1282X. Regarding the non azoospermic subjects, the prevalence of the CFTR and/or the IVS8-5T polymorphism was 11.1% (11/99 cases in severe dyspermia, 8.1% (6/74 cases in moderate dyspermia and finally 4.0% (1/25 cases in normospermic subjects. Conclusions. This study confirms the highly significant prevalence of CFTR mutations in males with bilateral absence of the vas deferens or ejaculatory ducts obstruction compared with subjects with secretory azoospermia. Moreover, the significant prevalence of mutations in severely dyspermic subjects may suggest the possible involvement of CFTR even in the spermatogenic process. This could explain the unsatisfactory recovery of sperm from testicular fine needle aspiration in patients affected by genital tract blockage.

  7. UBE2B mRNA alterations are associated with severe oligozoospermia in infertile men

    Oligozoospermia (low sperm count) is a common semen deficiency. However, to date, few genetic defects have been identified to cause this condition. Moreover, even fewer molecular genetic diagnostic tests are available for patients with oligozoospermia in the andrology clinic. Based on animal and gene expression studies of oligozoospermia, several molecular pathways may be disrupted in post-meiotic spermatozoa. One of the disrupted pathways is protein ubiquitination and cell apoptosis. A critical protein involved in this pathway is the ubiquitin-conjugating enzyme 2B, UBE2B. Absence of Ube2b in male mice causes spermatogenic meiotic disruption with increased apoptosis, leading to infertility. To examine the association between messenger RNA defects in UBE2B and severe oligozoospermia (0.1–10 × 106 cells/ml), sequencing of sperm cDNA in 326 oligozoospermic patients and 421 normozoospermic men was performed. mRNA alterations in UBE2B were identified in sperm in 4.6% (15 out of 326) of the oligozoospermic patients, but not found in control men, suggesting strong association between mRNA defects and oligozoospermia (χ2 = 19, P = 0.0001). Identified UBE2B alterations include nine splicing, four missense and two nonsense alterations. The follow-up screen of corresponding DNA regions did not reveal causative DNA mutations, suggesting a post-transcriptional nature of identified defects. None of these variants were reported in the dbSNP database, although other splicing abnormalities with low level of expression were present in 11 out of 421 (2.6%) controls. Our findings suggest that two distinct molecular mechanisms, mRNA editing and splicing processing, are disrupted in oligozoospermia. We speculate that the contribution of post-transcriptional mRNA defects to oligozoospermia could be greater than previously anticipated. PMID:23378580

    The aim of this study was to determine and examine the possible reasons for the difference in prostate cancer incidence between Asian men and North American men by literature review. Data regarding cancer incidence and mortality were obtained from the database of the International Agency for Research on Cancer (IARC). A literature review was conducted by studying related articles published in peer-reviewed journals such as the The New England Journal of Medicine, Journal of Clinical Oncology, A Cancer Journal for Clinicians and Asian Journal of Andrology. To evaluate the early diagnosis and survival rates, the mortality-to-incidence rate ratio (MR/IR) was calculated from the IARC data. By comparing prostate cancer data between Asian men and North American men, we found that differences in the incidence rate and MR/IR could be attributed largely to a lack of annual prostate cancer screening with serum prostate-specific antigen (PSA) in most Asian countries. It is likely that PSA screening also contributes significantly to the differences in prostate cancer mortality rates. Prostate cancer has the highest incidence rate among five common malignancies in Asian Americans. However, the MR/IR ratio of prostate cancer is the lowest among cancers. These data seem to further support the usefulness of PSA screening, even though the percentage of low risk cancers is greater in prostate cancer than in other cancers. The low incidence rate of prostate cancer does not reflect the actual statistics of this disease in Asia. The data from limited institutions in many Asian countries seem to bias the true incidence and mortality rates. To improve this situation, incorporating PSA screening for prostate cancer, as well as constructing a nationwide cancer registration system, will be helpful.

    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

    In the ever changing field of reproductive medicine, clinics are regularly confronted with requests for novel variants of medically assisted reproduction. Particularly third-party (assisted) reproduction, which requires the involvement of an oocyte or sperm donor, is ethically and psychologically complex due to the parties involved, but nevertheless widely accepted. A particular type of third party reproduction concerns intrafamilial medically assisted reproduction (IMAR), where the donor is a family member of the recipients. In IMAR, some of the ethical and psychological issues associated with third party reproduction are intensified. The precise impact and consequences, however, remain speculative due to the lack of information regarding IMAR. Both the ESHRE Task Force on Ethics and Law and the Human Fertilization and Embryology Authority have recently highlighted the lack of information and the need for debate. In order to contribute to the discussion and knowledge on IMAR, we present a couple that recently visited our academic clinic with a request for a very particular variant of IMAR: first degree, intergenerational father-to-son sperm donation. As our academic hospital did not have experience with this variant of IMAR, our interdisciplinary Ethics Committee for Reproductive Medicine extensively discussed the request, resulting in an advisory report on the ethics of IMAR in general and father-to-son sperm donation in particular. Here, we will first present the andrological and social background of the couple and subsequently discuss the ethical considerations that led to the approval of their request. We will conclude the paper with recommendations for a morally sound practice of IMAR.

    Because of unavoidable complications of vasectomy, this study was undertaken to assess the efifcacy and safety of male sterilization with a nonobstructive intravas device (IVD) implanted into the vas lumen by a mini-surgical method compared with no-scalpel vasectomy (NSV). IVDs were categorized into two types:IVD-B has a tail used for ifxing to the vas deferens (ifxed wing) whereas IVD-A does not. A multicenter prospective randomized controlled clinical trial was conducted in China. The study was comprised of 1459 male volunteers seeking vasectomy who were randomly assigned to the IVD-A (n= 487), IVD-B (n= 485) or NSV (n=487) groups and underwent operation. Follow-up included visits at the 3rd-6th and 12th postoperative months. The assessments of the subjects involved regular physical examinations (including general and andrological examinations) and semen analysis. The subjects’ partners also underwent monitoring for pregnancy by monthly interviews regarding menstruation and if necessary, urine tests. There were no signiifcant differences in pregnancy rates (0.65% for IVD-A, 0 for IVD-B and 0.21% for NSV) among the three groups (P>0.05). The cumulative rates of complications at the 12th postoperative month were zero, 0.9%and 1.7%in the three groups, respectively. In conclusion, IVD male sterilization exhibits a low risk of long-term adverse events and was found to be effective as a male sterilization method, similar to the NSV technique. IVD male sterilization is expected to be a novel contraceptive method.

    Data on the effects of recombinant human GH (hGH) therapy during male puberty on future testis function are still inconclusive. The aim of this study was to investigate the long-term effects of recombinant hGH treatment on reproductive function in non-GH-deficient short stature boys. Eight boys with non-GH-deficient short stature, affected by constitutional delay of puberty or idiopathic short stature, were retrospectively studied after recombinant-hGH treatment to verify gonadal development, hormone production and semen quality. Auxological data, endocrinological/ andrological parameters and laboratory evaluation (GH, IGF-I, FSH, LH, testosterone, inhibin B) were assessed before treatment; after completion of pubertal development, the same parameters plus SHBG levels were evaluated and a seminal fluid examination was conducted (ejaculate volume, pH, sperm concentration, total sperm count, forward and total motility, morphology). All patients showed normal testicular volume at the final pubertal stage, with regular androgenization. Hormonal levels were within the normal adult range in all boys. Considering the immature reproductive system of these patients in comparison with adults, semen parameters (sperm count, motility, and morphology) were within almost normal limits, except in one patient. Although patients showed the wide fluctuation of semen values frequently observed at the end of puberty, the hypophysis-gonadal axis hormones were in the normal range in all adolescents. Pathological measurements of some seminal parameters were found in one patient only. This study suggests that recombinant hGH treatment has no detrimental effects on the development and maturation of male gonadal function in non- GH deficient short stature young patients.

    Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges.

    The aim of this study was to evaluate the possible association between cardiometabolic risk factors accumulation and vitamin D status in a cohort of Italian normal weight and overweight male children. 108 boys enrolled in an andrological health prevention project underwent physical examination, anthropometric measurements, and fasting blood sampling. Serum blood glucose, HDL-cholesterol, triglycerides, parathyroid hormone, and 25-hydroxyvitamin D (25(OH)D) were measured. Cardiovascular risk factors were defined according to the National Cholesterol Education Program Adult Treatment Panel III modified for age. Lean and overweight subjects differed in terms of waist circumference (P < 0.001), HDL-cholesterol (P = 0.001), triglycerides (P = 0.001), systolic blood pressure (P < 0.001) and diastolic blood pressure (P = 0.002). Both groups had similar mean 25(OH)D levels (P = 0.160) and were below the sufficiency threshold: indeed only 24 % of normal weight had 25(OH)D ≥30 ng/ml, and even less in the overweight/obese group (8 %, P = 0.03 vs. normal weight). A significant accumulation of risk factors in course of 25(OH)D insufficiency was detected in both the whole cohort and in the normal weight group (P = 0.003 and P = 0.04, respectively) with odd ratios of 1.31 (1.16-1.49 95%CI) and 1.41 (1.18-1.69 95%CI), respectively. In course of vitamin D deficiency, the odd ratios were 2.24 (1.34-3.77 95%CI, P = 0.003) in the whole cohort and 2.40 (1.27-4.82 95%CI, P = 0.03) in lean subjects. We reported a considerable occurrence of cardiovascular risk factors in course of hypovitaminosis D in overweight/obese boys and even in lean subjects, which normally would not have been further evaluated by considering the sole BMI-related parameters. In this regard, 25(OH)D levels appear as a potential discriminating parameter able to identify male children at higher health risk.

    Full Text Available Introduction: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. Case report: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle. We then performed an ultrasound exam of the testis which highlighted the presence of an intra-didymus neoformation with diameters of 1.2 x 1.6 cm and with the presence of cysts inside. We also performed blood tests to check tumor markers alpha fetoprotein, beta hCG and LDH which resulted inside the normal range. We then conducted a chest and abdomen CT scan that showed no pathological elements. Therefore, as we suspected that this tumor was benign, we performed an enucleation of the neoplasm. The definitive histological examination revealed the presence of dilated ducts lined with epithelial cubic-columnar cells with clear cytoplasm rich in glycogen and the pathologist so concluded that the tumor could be classified as adenomatous hyperplasia of the rete testis. At three months of follow up, the patient doesn’t have any recurrent lesion to either testicles. Discussion: Adenomatous hyperplasia of the rete testis is a very rare intrascrotal lesion. This histological type is the most frequent between benign lesion of the ovary, but few works in literature reported this histological type in the male gonad and, in most of these works, authors described these lesion at epididymis. Conclusion: We believe that a conservative approach must be considered mandatory in case of testicular lesions 1.5 cm in diameter. A radical approach might have alterate fertility of the

    Full Text Available Background: Most of male infertility are caused by defect in sperm motility (asthenozoospermia. The molecular mechanism of low sperm motility in asthenozoospermic patients has not been fully understood. Sperm motility is strongly related to the axoneme structure which is composed of microtubules and supported by outer dense fiber (ODF and fibrous sheath (FS protein. The objective of this study was to characterize the ODF (ODF1 and ODF2 expression in asthenozoospermic infertile male and control normozoospermic fertile male.Methods: Asthenozoospermic samples (n=18 were collected from infertile patients at Andrology Lab, Cipto Mangunkusumo Hospital Jakarta and control were taken from normozoospermic fertile donor (n=18. After motility analyses by computer-assisted sperm analysis (CASA, semen were divided into two parts, for Western blot and for immunocytochemistry analysis. Antibody against ODF1 and ODF2 protein were used in both analyses.Results: Analysis of ODF1 protein expression showed bands with molecular weight of ~30 kDa and ODF2 ~85 kDa. The mean band intensity of ODF1 and ODF2 protein were lower in the asthenozoospermic group (AG compared to normozoospermic group (NG. Moreover, both ODF proteins were less intense and less localized in the AG than NG. Sperm motility was lower in AG, compared to control NG, i.e. average path velocity (VAP = 32.07 ± 7.03 vs 37.58 ± 8.73 µm/s, p = 0.455; straight line velocity (VSL = 24.17 ± 6.90 vs 27.61 ± 4.50 µm/s, p = 0.317 and curvilinear velocity (VCL = 45.68 ± 7.91 vs 55.55 ± 16.40 µm/s, p = 0.099.Conclusion: There is down-regulation of ODF1 and ODF2 protein expression and less-compact localization in AG sperm compared to the NG. These changes might have caused disturbances in the sperm motility as observed in this study.

    Multiplex polymerase chain reaction (PCR) has been widely used to detect Y-chromosome microdeletions,which is one of the major causes of male infertility.Both the European Academy of Andrology (EAA) and the European Molecular Genetics Quality Network (EMQN) have recommended the use of sY84 and sY86 markers for the detection of azoospermia factor a (AZFa) microdeletion during DNA testing for male infertility.In this study,a large-scale analysis of AZF microdeletion in a total of 630 Chinese males,including healthy semen donors (n=200),infertile males with normal sperm count (n=226) and patients with either nonobstructive azoospermia or severe oligozoospermia (n=204),was performed.A series of nine sequence-tagged site (STS) markers from the AZF region of the Y chromosome was used to detect microdeletions.All primers were designed based on the recommendations of the National Center for Biotechnology Information.An unusually high incidence (73/630,11.6%) of sY84-absent but sY86-present genotypes was observed in the AZFa microdeletion screening.Sequencing the sY84-flanking region revealed a total of 73 patients with sY84-absent but sY86-present genotypes have a T-to-G transversion at the fifth base from the 5' end of the reverse sY84 primer.These prevalent false positives,which were not only observed in infertile men,but also observed in donors,resulted from a single-nucleotide polymorphism (SNP) named rs72609647 in the targeting sequence of the reverse sY84 primer.Our study suggests that a pre-screening of existence of rs72609647 polymorphism can prevent the frequent false positive results of AZFa microdeletions detection in the infertile Chinese males.Given the SNP rs72609647 was recently found in a deep sequencing of a Chinese individual,the current EAA and EMQN standards may need to be scrutinized among different populations to avoid the potential genetic variations in the primer binding sequences.

    The aim of the study was to evaluate the seasonality of andrological characteristics and hormonal profile of captive maned wolves (Chrysocyon brachyurus, Illiger 1811). Three adult males were evaluated from the Companhia Brasileira de Metalurgia e Mineração Scientific Breeding Center in Araxá, MG, Brazil, over 13 months. Semen was collected 2-3 times weekly and analysed. Scrotal circumference, biometrics and testicular volume were measured. Stool samples were collected 2-3 times weekly to analyse corticosteroid and testosterone metabolite concentrations. A success rate of 100% was achieved in the collection attempts during the breeding season (BS) and 77.8% during the non-breeding season (NBS). The interval to achieve penile erection was 1-5 min in the BS and 6-10 in the NBS (p < 0.001). Of the ejaculates collected, 80.0% contained sperm during BS, while 28.6% did during the NBS. The ejaculate had only one fraction, was odourless, predominantly translucent (72.4%), with a watery appearance, pH 6.7 and osmolarity of 352.8 mOsmol. Seasonal influences were seen in ejaculate volume (1.3 ml vs 0.4 ml), number of spermatozoa per ejaculate (73.9 × 10(6) vs 6.1 × 10(6) ) and percentage of live sperm (82.0% vs 66.1%) between the BS and NBS (p < 0.05), respectively. A high percentage of major sperm defects were observed in both seasons (50.1% in BS; 65.7% in NBS). Testicular volume was larger (p < 0.05; right testicles 13.1 cm(3) in BS vs 4.0 cm(3) in NBS, while left testicles 12.9 cm(3) in BS vs 5.3 cm(3) in NBS) and testicular consistency increased in the BS. No difference was seen in the basal faecal metabolite concentrations of testosterone; however, the corticosteroid concentrations were higher in the BS. Based on these results, it is possible to conclude that the collection of semen is feasible in captive maned wolves without compromising libido, seminal characteristics and reproductive behaviour and that sperm production is influenced by seasonality; however, it

    Digito‑rectal examination(DRE) of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of ifnding an enlarged prostate size at DRE in subjects with sexual dysfunction(SD). Aconsecutive series of 2379patients was retrospectively studied. The analysis was focused on a subset of subjects(n=1823; mean age 54.7±11.4) selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome(HR=1.346(1.129–1.759);P=0.030), type2 diabetes mellitus(HR=1.489(1.120–1.980);P=0.006), increased LDL cholesterol(>100mgdl−1; HR=1.354(1.018–1.801);P=0.037) and increased mean blood pressure(BP) values(HR=1.017(1.007–1.027) for each mmHg increment;P=0.001). Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction(ED), as well as with other andrological conditions, such as varicocele and premature ejaculation(PE). PSA levels were signiifcantly higher in subjects with enlarged prostate size when compared to the rest of the sample(HR=3.318(2.304; 4.799) for each log unit increment in PSA levels;P<0.0001). Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical(DRE) or biochemical(PSA) inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular(CV) background of the patient.

Given the correlation between anogenital distance and genital development, we sought to determine if anogenital distance varied in fertile compared to infertile adult men. METHODS: A cross sectional study of consecutive men being evaluated for infertility and men with proven fertility was recruited from an andrology clinic. Anogenital distance (the distance from the posterior aspect of the scrotum to the anal verge and penile length (PL were measured using digital calipers. ANOVA and linear regression were used to determine correlations between AGD, fatherhood status, and semen analysis parameters (sperm density, motility, and total motile sperm count. FINDINGS: A total of 117 infertile men (mean age: 35.3±17.4 and 56 fertile men (mean age: 44.8±9.7 were recruited. The infertile men possessed significantly shorter mean AGD and PL compared to the fertile controls (AGD: 31.8 vs 44.6 mm, PL: 107.1 vs 119.5 mm, p<0.01. The difference in AGD persisted even after accounting for ethnic and anthropomorphic differences. In addition to fatherhood, on both unadjusted and adjusted linear regression, AGD was significantly correlated with sperm density and total motile sperm count. After adjusting for demographic and reproductive variables, for each 1 cm increase in a man's AGD, the sperm density increases by 4.3 million sperm per mL (95% CI 0.53, 8.09, p = 0.03 and the total motile sperm count increases by 6.0 million sperm (95% CI 1.34, 10.58, p = 0.01. On adjusted analyses, no correlation was seen between penile length and semen parameters. CONCLUSION: A longer anogenital distance is associated with fatherhood and may predict normal male reproductive potential. Thus, AGD may provide a novel metric to assess reproductive potential in men.

    Full Text Available The process of sperm maturation, capacitation, and fertilization occur in different molecular milieu provided by epididymis and female reproductive tract including oviduct. The different tissue environment with different oxygen tension and temperature may still influence the process of sperm maturation and capacitation. Reactive oxygen species (ROS is reported to be an initial switch that may activate the molecular process of capacitation. Therefore, the generation of reactive oxygen species and its possible physiological role depends upon a balance between its formation and degradation in an open environment provided by female reproductive tract. The sensitivity of the spermatozoa to the action of ROS may be due to its exposure for the first time to an oxygen rich external milieu compared to its internal milieu in the male reproductive tract. Reduced temperature in testicular environment coupled with reduced oxygen tension may be the right molecular environment for the process of spermatogenesis and spermiogenesis. The morphologically mature spermatozoa then may attain its motility in an environment provided by the caput epididymis wherein, the dyenin motor can become active. This ability to move forward will make the spermatozoa physiologically fit to undertake its sojourn in the competitive race of fertilization in a new oxygen rich female reproductive tract. The first encounter may be oxygen trigger or preconditioning of the spermatozoa with reactive oxygen species that may alter the spermatozoal function. Infertility is still one of the major global health problems that need medical attention. Apart from the development of artificial methods of reproduction and development of newer techniques in the field of andrology focuses attention on spermatozoal structure and metabolism. Therefore, understanding the molecular mechanisms involved in fertilization in general and that of sperm capacitation in particular may help lead to new and better

    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.

    Various microRNAs from the miR-371-3 and miR-302a-d clusters have recently been proposed as markers for testicular germ cell tumours. Upregulation of these miRNAs has been found in both the tissue and serum of testicular cancer patients, but they have never been studied in human seminal plasma. The aim of this study was, therefore, to assess the differences in the expression of miR-371-3 and miR-302a-d between the seminal plasma and serum of testicular cancer patients, and to identify new potential testicular cancer markers in seminal plasma. We investigated the serum and seminal plasma of 28 pre-orchiectomy patients subsequently diagnosed with testicular cancer, the seminal plasma of another 20 patients 30 days post-orchiectomy and a control group consisting of 28 cancer-free subjects attending our centre for an andrological check-up. Serum microRNA expression was analysed using RT-qPCR. TaqMan Array Card 3.0 platform was used for microRNA profiling in the seminal plasma of cancer patients. Results for both miR-371-3 and the miR-302 cluster in the serum of testicular cancer patients were in line with literature reports, while miR-371and miR-372 expression in seminal plasma showed the opposite trend to serum. On array analysis, 37 miRNAs were differentially expressed in the seminal plasma of cancer patients, and the upregulated miR-142 and the downregulated miR-34b were validated using RT-qPCR. Our study investigated the expression of miRNAs in the seminal plasma of patients with testicular cancer for the first time. Unlike in serum, miR-371-3 cannot be considered as markers in seminal plasma, whereas miR-142 levels in seminal plasma may be a potential marker for testicular cancer.

    STUDY QUESTION What are the primary causes of severe male factor infertility? SUMMARY ANSWER Although 40% of all patients showed primary causes of infertility, which could be subdivided into three groups based on the severity of their effect, ~75% of oligozoospermia cases remained idiopathic. WHAT IS KNOWN ALREADY There are few large-scale epidemiological studies analyzing the causes of male factor infertility. STUDY DESIGN, SIZE, DURATION A prospective clinical-epidemiological study was conducted at the Andrology Centre, Tartu University Hospital between 2005 and 2013, recruiting male partners of couples failing to conceive a child for over ≥12 months. Among 8518 patients, 1737 (20.4%) were diagnosed with severe male factor infertility. A reference group of fertile controls was comprised of 325 partners of pregnant women. PARTICIPANTS/MATERIALS, SETTING, METHODS The mean age of infertility patients and fertile controls was 33.2 ± 7.3 and 31.7 ± 6.3 years, respectively. All participants were examined using a standardized andrology workup, accompanied by a structured medical interview. Hormonal analysis included serum FSH, LH and testosterone. Semen quality was determined in accordance to the World Health Organization recommendations. Cases with spermatozoa concentrations of ≤5 million/ml were screened for chromosomal aberrations and Y-chromosomal microdeletions. MAIN RESULTS AND THE ROLE OF CHANCE The primary cause of infertility was defined for 695 of 1737 patients (~40%). The analyzed causal factors could be divided into absolute (secondary hypogonadism, genetic causes, seminal tract obstruction), severe (oncological diseases, severe sexual dysfunction) and plausible causal factors (congenital anomalies in uro-genital tract, acquired or secondary testicular damage). The latter were also detected for 11 (3.4%) men with proven fertility (diagnoses: unilateral cryptorchidism, testis cancer, orchitis, mumps orchitis). The causal factors behind the most

    Introduction and objective: In Europe, nearly every sixth couple in the reproductive age is involuntarily childless. In about 30%, both male and female reveal fertility problems. In about 10% of infertile men, azoospermia is the underlying cause. As conventional therapeutic options are limited, surgical testicular sperm extraction (TESE) is necessary to obtain sperms for assisted reproductive techniques. Regarding the females, up to 30% of all idiopathic infertilities are due to alterations of the uterine tube So far, no imaging technique, which does not require any labelling, is available to evaluate the male and female genital tract at a microscopic level under in vivo conditions. Thus, the aim of this study was to investigate the potential of optical coherence tomography (OCT) as a non-invasive diagnostic tool in gynaecology and andrology. Material and Methods: Tissues samples from the bovine testis, epididymis, vas deferens, ovary, oviduct (ampulla and isthmus) and uterus were obtained immediately after slaughter (14 cows aged 3 to 8 years and 14 bulls aged 3 to 6 years; breeds: Holstein- Friesian, and Deutsches Fleckvieh). Imaging was done by using the US Food and Drug Administration (FDA) approved probe-based Niris Imaging System (Imalux, Cleveland, Ohio, USA) and the Telesto 1325 nm OCT System and Ganymede 930 nm OCT System (Thorlabs Inc., Dachau, Germany). All images obtained were compared to histological images after paraffin embedding and HE staining. Results: OCT imaging visualized the microarchitecture of the testis, epididymis, spermatic duct and the ovary, oviduct and uterus. Using the Thorlabs systems a axial resolution of approx. 5μm and lateral resolution of 8- 15μm could be achieved. Different optical tissue volumes could be visualized, which depends on the optical penetration depth of the wavelength of the system used. While the tissue volume observed by probe based Imalux-OCT is similar to the used Thorlabs systems, the optical resolution is

    languages, such as Mosaic and Netscape, are now widely available, and they allow the casual user to access the most sophisticated multimedia aspects of computer information on a variety of different systems. Andrologists may thus use the World Wide Web to make inference engines that they have programmed available to other clinicians and researchers. For example, we programmed a World Wide Web interface to the neural networks that we trained in order to solve a number of andrology classification problems. Interested users connect to our address (at this writing http:@godot.urol.uic.edu), and they may fill out electronic forms with their own patient data, press a "predict" button, and nearly immediately view the results of our neural networks' prediction on their own computers. With the explosion in computer hardware technology, mathematics and computer science that once seemed esoteric can now be investigated on computers available to nearly all andrologists. Rapid advances in computer network technology now render a tool developed by one andrologist immediately available to many. Clearly, andrologists may expect that computational investigations in their field will be a productive ground in the near and far future.
