Male infertility is one of the complications associated with diabetes mellitus. This study reported the effect of managing experimentally-induced diabetes in male Wistar rats with Cleome rutidosperma leaf extract at doses of 100 mg.kg−1, 200 mg.kg−1 or 400 mg.kg−1 for 14 days. Further deterioration or amelioration of reproductive derangement was assessed by changes in sperm morphology, sperm characteristics, and testicular histo-pathology. Andrology profile of diabetic untreated rats showed significant (P < 0.05) derangements compared to normoglycaemic rats. The profile of diabetic rats treated with the extract of C. rutidosperma, especially at the 200 mg.kg−1 dose showed a significant decrease in abnormal sperm cells, increases in sperm motility, live/ dead ratio and count compared to the untreated diabetic rats. Histopathology showed spermatogenic arrest and degeneration of Sertoli cells in the diabetic untreated rats, but was restored in the C. rutidosperma treated rats. This study showed evidence of infertility associated with diabetes and the ameliorative ability of C. rutidosperma on infertility demonstrated by improved andrological parameters. Traditional management of diabetes with C. rutidosperma leaves should therefore be encouraged in both humans and other animals, especially males with reproductive intentions.

Abstract Background The testis is specific in that it produces haploid germ cells of which autoantigens newly appear long after the neonatal immune tolerance. Under normal condition, these autoantigens are protected by the blood‐testis barrier formed by Sertoli cells. Thus, the testis is an immunologically privileged site where haploid cells are protected from autoimmune attack. Methods The immunological microenvironment in the testis was experimentally investigated using mice and rats. Main findings Not only the blood‐testis barrier but also various immuno‐suppressive factors are involved in the immune‐privileged testis. Indeed, germ cells transplanted into the xenogeneic seminiferous tubules could proliferate and differentiate with no aid of artificial immunosuppression. On the other hand, autoimmune orchitis could be experimentally produced by various methods of immunization with syngeneic or xenogeneic germ cell antigens. Conclusion Our results indicate that the testis is immunologically privileged but also immunologically fragile organ. Therefore, the dual nature is critical for immunoregulation of testicular function.

The other important objective of ANDRONET is to improve professional education in clinical andrology, which is currently fragmented among several medical branches, and to contribute to the recognition of andrology as a medical subspecialty at the European level. Andrology, a multidisciplinary field of biomedicine devoted to male health, has long been fragmented and not well supported by research grant institutions and a poorly informed public.

Does intracytoplasmic sperm injection improve live birth rate when compared with conventional in vitro fertilization in non-male factor infertility? Novel use of COMET parameters of sperm DNA damage may increase its utility to diagnose male infertility and predict live births following both IVF and ICSI.

ICSI does not offer any benefit over conventional IVF across different ovarian response categories in non-male factor infertility: a European multicenter analysis. [Extracted from the article]

ABSTRACT This study aimed to evaluate the use of some testicular traits to identify boars with low sperm morphological quality. The consistency (scores from 1 to 5), tone with tonometry (mm), parenchyma echogenicity and heterogeneity with ultrasound (pixel) were assessed in 402 mature boars (18.5 months on average). Sperm abnormality thresholds (≤ 25% of total sperm abnormalities, ≤ 5% of heads, acrosome, neck or midpiece defects, ≤ 10% tail defects, and 15% cytoplasmic droplets) were used to classify boars as approved or disapproved. Three classes of testicular traits were formed (extremely low and high values, approximately 15% each, were kept in separated classes). When the traits were individually evaluated, fewer boars were approved if the echogenicity or heterogeneity were high, or if the tone was rigid. When evaluated in combination, the interaction between heterogeneity and tone, and between heterogeneity and echogenicity were significant. The high heterogeneity combined with soft tone or with hypo-echogenicity resulted in lower approval of boars. Tonometry and ultrasonography have a moderate potential to be included in breeding soundness examination of boars. When combined, they provide more reliable information about the impact of testicular parenchymal alterations on morphology of sperm cells.

Abstract Background The Co-word analysis has the ability to identify the intellectual structure of knowledge in a research domain and reveal its subsurface research aspects. Objective This study examines the intellectual structure of knowledge in the field of Andrology during the period 2008-2017 using Co-word analysis. Materials and Methods In this descriptive-analytical study with a scientometric approach, the WoS database was searched for papers indexed under “Andrology” over the period 2008–2017. The data were analyzed using Co-word, clustering methods, and strategic diagram with the help of SPSS, UcInet, RavarPreMap and VOSviewer software. Results The highest publication rate in the area of Andrology was seen in countries like the USA, China, Italy, and Iran. The top three journals that published papers on the field were Fertility and Sterility, Andrologia, Human reproduction. The results showed that the keyword “Spermatozoa” and two pairs of frequently used keywords, namely “Azoospermia * Oligospermia” were the most frequent in the field of Andrology. The results of hierarchical clustering led to 13 clusters. The clusters “Reproductive Techniques” and “Spermatogenesis” are the core clusters and play an effective role. The "Post-Testicular causes” and “Neoplasm” clusters are in marginal. Conclusion This study represented that Co-word analysis can well illustrate the intellectual structure of an area. Considering the frequency of keywords along with the clusters obtained, it seems that the majority of research approach was seen on infertility treatments, especially through assisted reproductive technology. Despite the importance of psychological aspects as well as education of reproductive health, these subjects have not been sufficiently considered.

Leukocytospermia is an ill-defined and poorly understood condition affecting up to 30% of male factor infertility. Current guidelines on leukocytospermia vary significantly, although it has been linked to increased rates of infertility, uncertainty about its clinical significance, diagnosis, and treatment remains. The guidelines are conflicting with sparse data scattered across different specialties and continents. This study aims to compare and contrast available international guidelines and recommendations. In addition to these guidelines, we sought to consolidate the findings of trials over the last several de-cades. English language articles on human observational studies, retrospective, prospective, clinical trials and randomized control trials were searched for using the following terms: “leukocytospermia, pyospermia, and male infertility.” Articles about treatment and management of leukocytospermia that were published between January 2010 and April 2018 were in-cluded, as well as four articles referenced in best practice and guideline statements from urological and andrological associa-tions. Disagreements on this topic are highlighted as some guidelines describe no correlation between leukocytospermia and infertility while others show that treatment leads to improvement of sperm quality by many measures including improved pregnancy rate. Various treatments have been suggested including antibiotics, anti-inflammatory medications, and frequent ejaculation. There is a need for definitive characterization of Leukocytospermia as an infectious or inflammatory marker and a re-evaluation of the leukocyte concentration threshold. Additional studies investigating rates of conception as a measure of outcome are needed, to provide greater level of evidence and generalizability of leukocytopsermia management.

Background and Objective: Infertility refers to the failure in achieving pregnancy of a couple after one year of regular sexual intercourse without using a protection method. The purpose of this research work was to evaluate the current status of the test and quality control performance in semen analysis in selected laboratories. Material and Methods: The semen analysis was performed in the Laboratory of Andrology in terms of macroscopic examination which include volume, color, viscosity, pH and acidity, and in terms of microscopy: the rate of sperm movement, the exact number of sperms per ml of semen, the percentage of sperm viability and movement, the presence of germ cells and white blood cells. Several questions for each part of the test were selected and answered by the director of the laboratories or andrology section supervisor. Results: There was a wide range in the performance of selected medical laboratories in Tehran regarding the standards of semen analysis according to the World Health Organization (WHO) Laboratory Manual for the examination and processing of human semen, fifth edition in 2010. They followed the instructions related to the sample collection in about 70% of the evaluated parameters, initial macroscopic examination in about 87% of the selected subjects, and the microscopic evaluation of sperm in about 65% of the test parameters. Conclusion: some laboratories do not follow the instructions of the WHO in performing semen analysis, and most of them do not follow the suggested methods in all parts of the test.

Penile Augmentation is a debatable issue among men community. Even though Self-conviction of penile size affected by many Factors. Many men seek it just to get confident. Although fillers gain popularity in soft tissue augmentation nowadays, there is no enough study trace these elements as long term follow up in this field. To our knowledge, we describe a rare case of late onset abscess after penile augmentation using hyaluronic acids (HAs) after 4 years without any risk factors.

Introduction: Our study analysed previous studies employing positron emission tomography with co‐registered computer tomography (PET/CT) in andrological patient evaluation and assessed the differences in 2‐[18F]F‐fluoro‐2′‐deoxyglucose (FDG) uptake between three groups: healthy testes, benign and malignant testicular pathology. Methods: Medline and Embase were systematically searched for studies involving FDG‐PET/CT imaging of testes with results expressed as mean standardised uptake value (SUVmean). A one‐way ANOVA was used to compare SUVmean between three groups. All papers assessing andrological parameters were pooled to compare fertility data. Results: Seventeen studies, including three relating to fertility diagnosis, with a total of 830 patients, were included in the review. One‐way ANOVA showed a statistical difference between mean values of tracer SUVmean in healthy and malignant testes (Dif. = −2.77, 95% CI = −4.32 to 1.21, p < 0.01) as well as benign and malignant (Dif. = −2.95, 95% CI = −4.33 to −1.21, p < 0.01) but no difference between healthy and benign (Dif. = 0.19, 95% CI = −0.96 to 1.33, p = 0.90). There is some evidence to suggest that FDG uptake and testicular volume are positively correlated to total sperm count, sperm concentration and sperm motility and that germ cells are likely to account for the majority of testicular FDG accumulation. Conclusion: Our findings indicate that malignant testicular lesions demonstrate a significantly higher FDG uptake than benign testicular lesions or healthy testes. Some evidence also suggests that FDG‐PET could visualise metabolic activity and thus spermatogenesis; however more studies are required to determine whether FDG‐PET could also be used to diagnose infertility. Further studies should focus on correlating both sex hormone‐serum levels and semen analysis results with imaging data. [ABSTRACT FROM AUTHOR]

Compared with cow fertility, genetic analyses of bull fertility are limited and based on relatively few animals. The aim of the present study was to estimate genetic parameters for semen characteristics of Norwegian Red bulls at the artificial insemination (AI) center (Geno AI station, Stange, Norway) and to estimate genetic correlations between some of these traits and andrology traits measured at the performance test station. The data from the AI center consisted of records from 137,919 semen collections from 3,145 bulls with information on semen weight, sperm concentration, motility before and after cryopreservation, motility change during cryopreservation, and number of accepted straws made. Data from the performance test station included 12,522 observations from 3,219 bulls on semen volume, concentration, and motility (%) when fresh and after storing for 24 and 48 h. Genetic parameters were estimated using linear animal repeatability models that included fixed effects of year-month of observation, age of bull, interaction between semen collection number, and interval between collections for all traits and type of diluter for postcryopreservation traits. The random effects included test-day, permanent environmental, and additive genetic effects of the bull. Based on records from the AI center, we found that semen weight, sperm concentration, and number of straws were moderately heritable (0.18–0.20), whereas motility had a lower heritability (0.02–0.08). Heritability of motility (%) was higher after cryopreservation than before. Genetic correlations among the semen characteristics ranged from unfavorable (−0.35) to favorable (0.93), with standard errors ranging from 0.02 to 0.22. Among the most precise genetic correlation estimates, number of straws made from a batch correlated favorably with semen weight (0.62 ± 0.06) and sperm concentration (0.44 ± 0.08), whereas sperm concentration was negatively correlated with weight (−0.33 ± 0.09). The genetic correlation between motility (%) before and after cryopreservation was 0.64 ± 0.14, and motility change during cryopreservation had a strong favorable genetic correlation with motility after cryopreservation (−0.93 ± 0.02). The estimated genetic correlation (standard error) between the traits volume, concentration, and motility when fresh measured at the performance test station and their respective corresponding traits at the AI center were 0.83 (0.05), 0.78 (0.09), and 0.49 (0.31). The final product at the AI center (number of accepted straws) correlated genetically favorably with all semen characteristic traits recorded at the performance test station (ranging from 0.51 to 0.67). Our results show that the andrology testing done at the performance test station is a resource to identify the genetically best bulls for AI production. [ABSTRACT FROM AUTHOR]

Introduction: Post-radical prostatectomy erectile dysfunction (post-RPED) is a common and potentially devastating complication. The role of PDE5-inhibitors (PDE5-Is) in post-RPED is controversial and invasive pharmacological treatments are associated with poor long-term compliance. Vacuum erection devices (VEDs) are a non-pharmacological alternative. Little data regarding VED efficacy and associated patient satisfaction in post-RPED exists. This study aimed to investigate the outcomes of VED therapy in a post-robot assisted radical prostatectomy (post-RARP) population. Methods: All men who underwent RARP at a single centre between February 2015 and October 2017 attended a nurse-led holistic-needs-assessment (HNA) appointment at 10 weeks post-RARP. All men identifying ED as a concern at HNA were offered dedicated nurse-led post-RPED clinic and VED clinic appointments. A cross-sectional survey of patient reported outcomes in these men was performed. Results: In total 137/539 (25%) men reported ED as a concern at HNA. All 137 men attended the VED clinic, 124/137 (90%) responded to the survey. Commonest reason for choosing VED therapy was for combined psychological, penetration and lengthening purposes (48%). Median time from RARP to VED clinic and from VED clinic to survey was 122 days (range 56–595) and 462 days (range 66–932) respectively. At survey 88/124(70.9%) reported continued use of VED, 69/88 (78%) of this group perceived VED treatment to be successful. Of those who had stopped using VED, 7/36 (19%) felt it had been successful. Key reasons for discontinuation were either because men felt it ineffective (13/36 (37%)) or disliked the device (10/36 (29%)). Conclusion: VED therapy is an effective treatment for men with post-RARP ED that is well tolerated with good short- to medium-term compliance. Up to two-thirds of men may find overall satisfaction with their post-RPED after VED therapy. Level of Evidence: 3 [ABSTRACT FROM AUTHOR]

Purpose: To determine if oocyte denudation and ICSI at 36.5 versus 39 h post HCG and/or Lupron trigger (2.5 h versus 5 h post-oocyte retrieval) influences fertilization and blastulation rates in good prognosis couples Methods: We performed a prospective, randomized controlled trial of 12 patients undergoing IVF with ICSI at an academic fertility center, resulting in 206 MII oocytes analyzed. At time of retrieval, patients with more than 10 oocytes retrieved had their oocytes randomized into two groups—one group for oocyte denudation and ICSI at 36.5 h post HCG and/or Lupron trigger and the other group for these procedures at 39 h post HCG and/or Lupron trigger (2.5 and 5 h after oocyte retrieval). Primary outcomes were fertilization and blastulation rates. Results: No difference was observed in fertilization rate, total blastulation rate, or day of blastulation based on timing of denudation and ICSI (all p > 0.05). Multiple regression analyses for fertilization and blastulation controlling for age and BMI revealed no difference in fertilization based on time of ICSI (p = 0.38, 0.71, respectively). A conditional logistic regression to account for multiple oocytes derived from each patient also found no difference in fertilization or blastulation based on timing of ICSI, even when controlling for age and BMI (p = 0.47, 0.59, respectively). Conclusion(s): In good prognosis couples, we observed no difference in fertilization or blastulation rates based on timing of ICSI within the currently accepted 2- to 6-h window post-retrieval based on a 34-h trigger. The oocyte appears to have a physiological tolerance for fertilization during this window of time, and variability in the timing of ICSI during this window is unlikely to have an impact on cycle outcome.

The anabolic–androgenic steroids (AAS) are clinically used as an androgen replacement, in hypogonadism treatment, to induce puberty, and also in the treatment of chronic degenerative diseases. The AAS use out of clinical context is becoming massively, being used merely for aesthetic reasons. AAS abuse may cause severe disarrangement on the HPG axis and generate a significant decrease in testosterone synthesis and secretion by the testes. This review aims to evaluate whether the hypogonadism induced by AAS abuse is reversible and under what circumstances the reversibility is possible. For this, PRISMA guidelines and several databases are used between July and September 2020. Altogether, this systematic review identified and analysed 179 cases of AAS users. Of these, 168 cases had the hypogonadism clearly diagnosed and proven to be linked exclusively to AAS abuse. However, between these 168 cases, only 38 cases presented fully known outcomes and among these, merely in 4, the hypogonadism was completely reversible (2 based on drug therapy) with HPG axis recovery. In conclusion, this review presents evidences that AAS‐induced hypogonadism is a seriously underestimated problem, and in the majority of cases, full recovery is very difficult to succeed.

Erectile dysfunction (ED) is a common condition encountered by an array of subspecialists and is the most cited research topic within the field of andrology. This bibliometric analysis aims to identify the most influential papers that inform current clinical practice and likely shape future research. The Thompson Reuters Web of Science citation database was interrogated using search terms to cover the breadth of erectile dysfunction. Results were ranked according to citation number with country of origin, journal, topic, year of publication, author and institution also analysed. The search criteria matched 12,570 manuscripts. The top 100 highest citation ranged from 3013 to 161 (median 229.5). The most cited manuscript reports the prevalence and risk factors of ED within the Massachusetts Male Aging Study. The most manuscripts were published by the Journal of Urology (n = 15) with a total of 7913 citations. Institutions from the USA contributed the majority (n = 55) with the UK (n = 14) second. The most common theme represented was epidemiology (n = 46) followed by treatment (n = 27). This analysis provides a list of the most influential manuscripts within ED and illustrates what can be considered a 'highly citable' paper. The most influential papers in Erectile Dysfunction remain seminal works from the end of the last century. The most cited manuscript has been cited 194 times in the last 17 months showing its continued value. Only one paper published within the last decade has reached the top twenty exemplifying the relative lack of novel influential publications. [ABSTRACT FROM AUTHOR]

Wild cat species are often in a vulnerable or endangered situation around the globe. One of the questions on which the researchers' efforts have focused is on aspects of reproduction with specimens in captivity, or on collecting genetic materials from wild animals for their multiplication in captivity. The objective of this review was compilation, ordering and synthesis of scientific information about biotechnologies in wild cats. This review was carried out compiling information published online on the subject for a period of 18 months; the information was synthesized and grouped into subtopics. Among the topics to highlight focus in the male parent approach allows for greater dispersal of genetic material compared to the female parent. During the application of technologies that assist reproduction, the collection, analysis and cryopreservation of semen is carried out, as well as the measurement of physical characteristics of the animals correlated with reproductive aspects. The main findings indicate that the investigation of methodologies such as seminal harvest by urethral catheterization, the development of cryopreservation protocols, and computer-assisted analysis of spermatic behavior are emerging biotechnologies, which allow expanding knowledge about the reproduction of felids. However, it should be considered for future research that the processes must be adapted for in situ work. In conclusion, the generation of information on these reproductive biotechnologies is a fundamental aspect for supporting sparse populations, to avoid the removal of specimens from their natural habitat, or the reintegration into it.

Peyronie's disease is a chronic inflammatory disease involving the formation of plaque in the tunica albugínea of the corpora cavernosa, resulting in penis deformity. It is often associated with penile pain, especially in younger patients, but it is not rare for pain to be absent; the disease is also associated with erectile dysfunction and a depressive state in a large percentage of cases. Objective: Aim of our study was to explore the basic knowledge base and diagnostic and therapeutic practice patterns in Peyronie's disease (PD) of a large number of physicians belonging to the Italian Andrology Society (SIA). Methods: Our survey is based on two questionnaires which were e-mailed to the members of the SIA. The first questionnaire explored diagnostic and therapeutic practice patterns of SIA physicians, while the second questionnaire focused on their knowledge of the disease, as well as their training and level of experience in the specific field. We then planned to compare our outcomes with similar PD surveys from other countries. Results: The first questionnaire was answered by 142 SIA physicians. The second questionnaire was answered by 83 SIA physicians. Most respondents (74.6%) chose penile ultrasonography as first-line diagnostic approach and 47.1% prefer to perform a color Doppler ultrasound after pharmaco-induced erection. Concerning the therapeutic practice patterns in active stage of the disease, most respondents (99.29%) prefer conservative medical therapy. Additionally, most respondents (64.78%), when failure of conservative treatment had been established, considered surgical treatment necessary, specifically corporoplasty, which may be associated with other techniques. Conclusions: The results of our survey show that, in comparison to their foreign counterparts, Italian SIA uro-andrologists have a more proactive diagnostic approach right from when patients first present. When PD is still in its active stage, SIA uro-androl-ogists mostly opt for medical therapy. In advanced disease or if conservative treatment fails, our survey indicates a greater preference for surgical treatment. Answers to the theoretical knowledge questions showed that SIA physicians have a good understanding of the disease's etiology, epidemiology, and clinical picture, and of the appropriate indications for treatment.

Objective: To investigate the anogenital distance in patients with and without testicular microlithiasis (TML). Methods: A total of 101 patients underwent a conventional standard clinical B-mode scrotal ultrasonography and scrotal MRI. The patients were divided into two groups: patients with TML and non-TML. The latter served as control group. The anogenital distance was measured by a straight line from center of the anus to the posterior base of scrotum using MRI. Results: In the TML group, mean AGD was 5.4 (± 1.07) cm (range 29–79 mm), and in non-TML 5.9 (± 1.03) cm (range 35–85 mm) (p = 0.04). Conclusion: MRI is a useful tool to measure the AGD. It is easy to perform without any discomfort to patients. We found AGD to be lower in patients with TML. [ABSTRACT FROM AUTHOR]

Penile dorsal nerve somatosensory evoked potential (DNSEP) is a scientific and objective technique that provides effective and objective data to establish the diagnosis of premature ejaculation (PE). To explore differences in DNSEP between patients with primary premature ejaculation (PPE) and those with secondary premature ejaculation (SPE), in order to investigate the clinical value of DNSEP in the diagnosis of PE. The participants were divided into a PPE group (34 cases), an SPE group (25 cases) and a healthy control group (18 cases). All participants underwent DNSEP testing, and the latencies and amplitudes of DNSEP were recorded. Differences in the latencies and amplitudes of DNSEP were compared among the PPE, SPE, and healthy control groups. The latencies of DNSEP in the PPE and SPE groups were shorter than those in the healthy control group, and these differences were statistically significant (P < 0.01). However, there was no statistically significant difference between the PPE and SPE groups (P > 0.05). The amplitudes of DNSEP in the PPE group were significantly higher than those in the healthy control group (P < 0.01). However, the amplitudes of DNSEP in the SPE group were significantly lower than those in the healthy control group (P < 0.05). PPE and SPE can be differentiated based on differences in the amplitudes of DNSEP, providing an objective basis for treatments and follow-up examinations. We evaluated differences in the amplitudes of DNSEP between PPE and SPE patients, which were rare in the published literature. However, specific causes of these differences are still unclear. SEP only reflects afferent pathways in the ejaculatory reflex arc, and role of the brain as a higher center should not be ignored. Both PPE and SPE patients are characterized by an increased excitability of the penile sensory nerves. Sun Z, Liao Z, Zheng Q, et al.

In 2020, the COVID‐19 pandemic led to the suspension of the annual Summer Internship at the American Center for Reproductive Medicine (ACRM). To transit it into an online format, an inaugural 6‐week 2020 ACRM Online Mentorship Program was developed focusing on five core pillars of andrology research: scientific writing, scientific methodology, plagiarism understanding, soft skills development and mentee basic andrology knowledge. This study aims to determine mentee developmental outcomes based on student surveys and discuss these within the context of the relevant teaching and learning methodology. The mentorship was structured around scientific writing projects established by the team using a student‐centred approach, with one‐on‐one expert mentorship through weekly formative assessments. Furthermore, weekly online meetings were conducted, including expert lectures, formative assessments and social engagement. Data were collected through final assessments and mentee surveys on mentorship outcomes. Results show that mentees (n = 28) reported a significant (p <.0001) improvement in all criteria related to the five core pillars.

Infertility is on a rise, and so is the availability of assisted reproductive technique (ART) centres. The sole aim of these centers is to help these unfortunate couples achieve pregnancy. Hence, the concentration of the treatment is on the female partner, while the male is relegated to just being a source for sperm. In the era of intracytoplasmic sperm injection, when pregnancy is possible even with a single mature sperm, evaluation and management of male factor infertility (MFI) is often neglected. MFI and poor semen parameters are markers of male health. He could be suffering from erectile or ejaculatory issues or with correctable obstructive azoospermia. A simple timely varicocele correction may help resolve the issue. It is important to understand that MFI is not a disease but may be a symptom of major underlying clinical condition like testicular or brain tumors. Infertility treatment could be the only occasion when a male seeks health‑care evaluation. India has a large pool of qualified urologists trained in andrological care. In contrast, gynecologists may not be trained in the management of male patients, hence there is an important place for andrological services to be an integral part of ART centers. Andrologists would offer minimal andrological evaluation and condition‑specific treatment. This could avoid or reduce the need for invasive and expensive ART. Andrologists could also choose the most appropriate mode of sperm retrieval. Undoubtedly, availability of andrological services would improve the overall quality of care, reduce the costs and complications, and would also be medicolegally safe. [ABSTRACT FROM AUTHOR]

Purpose: The Accreditation Council of Graduate Medical Education (ACGME) establishes surgical minimum numbers of cases for urologic training. Currently there is not a requirement for microsurgery, likely from a belief that programs do not offer exposure. In an effort to evaluate the availability of microsurgery training among urology residency programs we surveyed the programs. Materials and Methods: We obtained a list of the 138 ACGME-accredited urology residencies and contact information the American Urology Association (AUA). We contacted the residency programs by phone and e-mail. For programs that did not reply, we performed a search of the program website. We answered 3-questions to assess resident subspecialty training in microsurgery and used penile implant and artificial urinary sphincters as a comparison. Data are reported as frequencies. Results: We obtained data from 134 programs (97.1%). A total of 104 programs (77.6%) had fellowship-trained physicians for training in microsurgery, 86.6% for penile implants, and 88.8% for artificial urinary sphincters. The percentage of fellowshiptrained microsurgeons per program did not vary significantly when comparing the different sections of the AUA. The northeast and southeast sections had the lowest percentage (67% and 68%). Conclusions: Nearly 80% of urology residency programs have a fellowship-trained microsurgeon on faculty, we therefore believe that microsurgery should be added as part of the ACGME minimums. In order to provide an equal exposure to all graduating urology residents, urology residency programs that lack microsurgery should identify potential faculty with fellowship training.

Purpose: Intracavernosal injections are used to treat erectile dysfunction. Patient compliance with intracavernosal injections is required for success, though factors influencing compliance are unknown. This study aimed to identify factors that influence compliance with intracavernosal injections among men with erectile dysfunction., Materials and Methods: A retrospective analysis was conducted using men who were prescribed intracavernosal injections between 2017 and 2022 at an academic medical center in a cosmopolitan area. Custom Python code was used to capture the first and last prescription refill events, and the duration of intracavernosal injection use was calculated. Additional patientrelated data, including demographics and comorbidities, were gathered through chart reviews. Cox Proportional Hazards Regression models were used to evaluate the effects of predictor variables on the duration of intracavernosal injection use., Results: A total of 4,072 patients were included in the analysis. The study revealed that age significantly predicted discontinuation of intracavernosal injection therapy, showing an elevated hazard ratio of 1.007 for each additional year of age (p<0.001). Men who preferred to speak Spanish as their primary language was a significant predictor of discontinuation of injection therapy, showing a hazard ratio of 1.163 compared to those who preferred English (p=0.004). Men with a history of prostate cancer treatment stayed on treatment for 80 days fewer on average than those without (p=0.002)., Conclusions: Older age, prior history of prostate cancer treatment, and men who preferred to speak Spanish were all identified as factors potentially associated with reduced continuation of intracavernosal injection therapy for erectile dysfunction. Understanding these factors can help healthcare providers in both patient selection and counseling when discussing treatment options for erectile dysfunction., Competing Interests: The authors have nothing to disclose., (Copyright © 2024 Korean Society for Sexual Medicine and Andrology.)

Male infertility represents a significant global problem due to its essential health, social, and economic implications. It is unsurprising that scientific research is very active in this area and that advances in the diagnostic and therapeutic fields are notable. This review presents the main diagnostic advances in male infertility, starting from the changes made in the latest WHO Manual of semen analysis and discussing the more molecular aspects inherent to "omics". Furthermore, the usefulness of artificial intelligence in male infertility diagnostics and the latest advances in varicocele diagnosis will be discussed. In particular, the diagnostic path of male infertility is increasingly moving towards a personalized approach to the search for the specific biomarkers of infertility and the prediction of treatment response. The treatment of male infertility remains empirical in many regards, but despite that, advances have been made to help formulate evidence-based recommendations. Varicocele, the most common correctable cause of male infertility, has been explored for expanded indications for repair. The following expanded indications were discussed: elevated sperm DNA fragmentation, hypogonadism, orchalgia, and the role of varicocele repair in non-obstructive azoospermia. Moving forward with the available data, we discussed the stepwise approach to surgical sperm retrieval techniques and the current measures that have been investigated for optimizing such patients before testicular sperm extraction. Finally, the key points and expert recommendations regarding the best practice for diagnosing and treating men with infertility were summarized to conclude this review.

Penile abscesses of the corpus spongiosum are rare in urology, with few documented cases. These abscesses may occur spontaneously or due to risk factors such as diabetes mellitus, intracavernosal injection therapy, tuberculosis, trauma, and perianal or intra-abdominal abscesses. This report discusses a 76-year-old man who developed a penile abscess involving the corpus spongiosum following intermittent self-dilatation. This required open drainage together with antibiotic cover to clear the infection, and follow-up in an andrology clinic found no remnant abscess. This case highlights the importance of early diagnosis and intervention in penile abscesses, typically managed with imaging, drainage, and culture-directed antibiotics. The drainage options may include open or an ultrasound-guided approach, depending on the size and location. A multidisciplinary approach is crucial, with careful follow-up to manage potential complications such as penile deviation and erectile dysfunction. Pre-procedural counseling is essential, particularly in cases involving urethral instrumentation., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Accumulating evidence suggests a link between vascular endothelial growth factor (VEGF), erectile dysfunction (ED), and metabolic syndrome (Mets), possibly because VEGF can alter the physiological pathways involved in the regulation of endothelial cell proliferation. This study aimed to investigate the genetic susceptibility of VEGF 2578C>A polymorphism to the development of ED and Mets. Collected data included five-item International Index of Erectile Function (IIEF-5), components of Mets, and VEGF 2578C>A polymorphism. A total of 596 subjects from Kaohsiung with a mean age of 55.5 years were enrolled, data collection was done at our hospital. Individuals carrying the VEGF 2578 A allele (CA+AA genotypes) demonstrated a higher prevalence of ED compared to those with the CC genotype, with an adjusted odds ratio (OR) of 1.582 (95% confidence interval [95% CI] = 1.123-2.227, p value = 0.009) in multivariate binary regression analysis. Similarly, individuals carrying the VEGF 2578 A allele showed a higher prevalence of Mets compared to those with the CC genotype, with an adjusted OR of 2.461 (95% CI = 1.491-4.064, p value < 0.001). Furthermore, A allele carriers had significantly lower IIEF-5 scores and a higher number of Mets components compared to those with the C allele ( P value < 0.001, respectively). In conclusion, VEGF 2578 A allele carriers are at a greater risk of both Mets and ED, suggesting that the VEGF 2578C>A polymorphism may serve as a common genetic susceptibility factor in the development of both disorders. Further research is warranted to evaluate the mechanisms underlying this association., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The continuous improvement and development of fertility care, internationally, requires ongoing monitoring of current delivery processes and outcomes in clinical practice. This descriptive and exploratory mixed-methods study was conducted in eight countries (Brazil, China, France, Germany, Italy, Mexico, Spain and the United Kingdom) to assess the unmet needs of fertility patients (male and female), and existing challenges, barriers and educational gaps of physicians and laboratory specialists involved in human fertility care during the COVID-19 pandemic., Materials and Methods: The study was deployed sequentially in two phases: 1) in-depth 45-minute semi-structured interviews (n=76), transcribed, coded and thematically analysed using an inductive reasoning approach, 2) an online survey (n=303) informed by the findings of the qualitative interviews, face validated by experts in reproductive medicine, and analysed using descriptive and inferential statistical methods., Results: The integrated results of both phases indicated numerous areas of challenges, including: 1) investigating male-related infertility; 2) deciding appropriate treatment for men and selective use of assisted reproductive technology; and 3) maintaining access to high-quality fertility care during a pandemic., Conclusions: The paper presents a reflective piece on knowledge and skills that warrant ongoing monitoring and improvement amongst reproductive medicine healthcare professionals amidst future pandemics and unanticipated health system disruptions. Moreover, these findings suggest that there is an additional need to better understand the required changes in policies and organizational processes that would facilitate access to andrology services for male infertility and specialized care, as needed., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Creatinine (Cr) is often used as a standalone gold standard marker of kidney function. Cystatin C (Cys C) is a less physiologically labile marker of renal function, particularly in certain subgroups. Herein, we analyze trends in cystatin C as compared to creatinine in men on testosterone replacement therapy with varying body mass indices and percent body fat (PBF). This retrospective analysis observes 227 men with testosterone-induced muscle hypertrophy who visited a men's health tertiary care clinic. All participants were characterized as competitive or recreational athletes. In patients with a normal body mass index (BMI), there was no clinically significant correlation between Cr and Cys C. Slight correlation was seen with overweight ( R 2  = .27) patients ( p < .0001) and obese ( R 2  = .29) patients ( p < .0001). Patients with PBF of 0%-10% ( n  = 22) exhibited minimal ( R 2  = .23) positive correlation between Cys C and Cr ( p  = .03). Positive correlation between Cys C and Cr in patients with PBF of 10%-20% was clinically negligible ( R 2  = .17, n  = 87), modest ( R 2  = .49) in patients with PBF of 20%-30% ( n  = 42), and evident ( R 2  = 1.00) in patients >30% ( n  = 3) ( p < .0001, respectively). Cystatin C measurements display less variance compared with creatinine at differing BMI distinctions. At the upper limit of BMI or PBF in our patient population, cystatin C exhibits minimal to moderate variability compared with creatinine., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Peyronie's disease (PD) is a common benign condition characterized by superficial fibrosis and scar formation at the tunica albuginea of the penis, eventually leading to penile curvature. It is believed that penile micro-traumas during intercourse and subsequent activation of inflammatory processes constitute the pathogenetic basis of the disease. Routinely, PD is divided into acute and chronic phases, with pain during erection or flaccid state being the hallmark of the former. Surgical intervention should be avoided during the acute phase, as the risk of recurrence or progression of penile deformity during this stage might affect the optimal outcomes of the procedure. During this stage, many conservative treatment options have been suggested, including oral, topical, and intralesional therapies, extracorporeal shock wave therapy (ESWT), and penile traction therapy (PTT). Currently, the optimal treatment consists of a combined treatment strategy with phosphodiesterase type 5 inhibitors (PDE5Is), ESWT for pain management, PTT, and intralesional therapies. Large, well-designed randomized controlled trials (RCTs) are necessary to further elucidate the most efficient treatment option for acute phase PD., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Azoospermia, the absence of sperm cells in semen, affects around 15% of infertile males. Sertoli cell-only syndrome (SCOS) is the most common pathological lesion in the background of non-obstructive azoospermia and is characterised by the complete absence of germinal epithelium, with Sertoli cells exclusively present in the seminiferous tubules. Studies have shown a correlation between successful spermatogenesis and male fertility with lipid composition of spermatozoa, semen, seminal plasma or testis. The aim of this research was to discover the correlation between the Johnsen scoring system and phospholipid expressions in testicular cryosections of SCOS patients. MALDI imaging mass spectrometry is used to determine spatial distributions of molecular species, such as phospholipids. Phosphatidylcholines (PCs), phosphatidylethanolamines (PEs) and sphingomyelins (SMs) are the most abundant phospholipids in mammalian cells and testis. SMs, the structural components of plasma membranes, are crucial for spermatogenesis and sperm function. Plasmalogens, are unique PCs in testis with strong antioxidative properties. This study, using imaging mass spectrometry, demonstrates the local distribution of phospholipids, particularly SMs, PCs, plasmalogens and PEs in human testicular samples with SCOS for the first time. This study found a strong relationship between the Johnsen scoring system and phospholipid expression levels in human testicular tissues. Future findings could enable routine diagnostic techniques during microTESE procedures for successful sperm extraction.

Small non-coding RNAs such as small interfering RNA (siRNA), microRNA (miRNA) and piwi-interacting RNA (piRNA) exist in almost all kingdoms of organisms and have recently emerged as master regulators of gene expression to affect a diverse range of important biological processes. They exert their functions largely through two related but opposing mechanisms: RNA interference (RNAi) mediated by siRNA, miRNA and piRNA, and RNA activation (RNAa) mediated by small activating RNA (saRNA) and miRNA, leading to silencing and overexpression of target genes respectively. Dysregulation of these mechanisms have been implicated in a variety of human diseases including urological and andrological diseases. Importantly, both mechanisms can be readily harnessed for therapeutic purposes for a variety of diseases by using small RNA molecules as the "ribodrug". In this review, we highlight recent advances in the applications of small RNA as therapeutics for urological cancer, male infertile and erectile dysfunction.

Introduction: Severe Acute Respiratory Syndrome Coronavirus 2, (SARS-CoV-2) was first identified by the Chinese Centers for Disease Control and Prevention on January 8, 2020 and was declared as a global pandemic on March 11, 2020 by WHO. SARS-CoV-2 uses the Angiotensin-converting enzyme 2 (ACE2) receptor as an entry route, associated with the transmembrane serine protease protein (TMPRSS2), which makes the testis and particularly spermatogenesis potentially vulnerable, since this tissue has high expression of ACE2. Material and methods: We performed a systematic literature review by electronic bibliographic databases in Pubmed, Scopus and ScienceDirect up to August 2020 about the effect of SARS-CoV-2 on male sexual function and its transmission, to assess possible repercussions on sex organs and the existence of a sexual transmission path. Results: Although SARS-CoV-2 presence has not been found in testicle samples, it has been demonstrated that it causes histological changes compatible with orchitis, and sex hormone disturbances. TMPRSS2 is up-regulated in prostate cancer where it supports tumor progression, thus these patients may have a higher risk of SARS-CoV-2 infection. TMPRSS2 inhibitors may be useful for the treatment or prevention of COVID-19. No viral material has been found in blood or semen, however it has been proven to be present in stool and saliva. Conclusion: The male reproductive system would be highly vulnerable and susceptible to infection by SARS-CoV-2 given the expression of the ACE2 receptor in somatic and germ cells. The seminal fluid would remain free of viral presence in patients with COVID-19. Regardless, non-genital sex could be an important source of viral transmission. In assisted reproduction techniques all necessary tests must be carried out to ensure the donor is free of the virus at the time of collection and handling of the seminal sample.

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) was first reported in December 2019, then its rapid spread around the world caused a global pandemic in March 2020 recording a high death rate. The epicenter of the victims moved from Asia to Europe and then to the United States. In this Pandemic, the different governance mechanisms adopted by local health regional authorities made the difference in terms of contagiousness and mortality together with a community strong solidarity. This document analyzes the andrological urgencies management in public hospitals and in private practice observed in Italy and in particular in the most affected Italian Regions: Emilia-Romagna and Marche.
