Testosterone levels increase following bariatric surgery - validation of preceding literature in a large-scale population analysis.

BACKGROUND: The effects of bariatric surgery on testosterone levels in men with obesity and hypogonadism have not been thoroughly explored yet. OBJECTIVES: To investigate the possible effects of bariatric surgery on T levels in obese hypogonadal men by comparing T levels before and after surgery using a comprehensive claims database. MATERIALS AND METHODS: The TriNetX US Collaborative Network database was used to identify men ages 18-80 who underwent a bariatric procedure and had a serum T value of < 350 ng/dL prior to surgery. Men who received testosterone therapy before/or after surgery were excluded. We conducted a retrospective self-matched cohort analysis to examine the difference in serum T levels before and after bariatric surgery. A sub-analysis was carried out to explore differences between men who reached eugonadal status or maintained low T levels following surgery. Descriptive statistics detailed sociodemographic and clinical characteristics, with continuous and categorical data compared using unpaired t-tests and chi-square analysis, respectively. Changes in T levels and body mass index (BMI) before and after surgery were compared using an unpaired t-test with a < 0.05 set for significance. All analyses were conducted using the TriNetX platform which utilizes both Python and R software. RESULTS: The study analyzed 69 hypogonadal men who underwent bariatric surgery and had T levels assessed before and after the procedure. The mean (standard deviation) pre-surgery serum T level was 208 ± 79 ng/dL, which post-surgery increased to 371 ± 164 ng/dL, marking an average increase of 163 ± 164 ng/dL. Likewise, the mean (standard deviation) body mass index decreased from 42.9 ± 9.0 to 38.8 ± 5.7 kg/m2. Post-surgery, 45% (31 men) achieved eugonadal status, while 55% (38 men) continued to have low T levels. A comparison between the post-surgery eugonadal cohort and the persistent low T cohort revealed that the former had higher pre-surgery serum T levels (235 ± 71 ng/dL vs. 184 ± 80.4 ng/dL, p = 0.007), a higher pre-surgery body mass index (45.5 ± 4.5 kg/m2 vs. 41.1 ± 11.5 kg/m2, p = 0.041), and a significantly greater reduction in body mass index post-surgery (7.3 ± 7.2 kg/m2 vs. 2.0 ± 12.8 kg/m2, p = 0.04). Notably, the increase in T was significantly higher in the eugonadal cohort compared to the persistent low testosterone cohort (257 ± 143 ng/dL vs. 95 ± 178 ng/dL, p < 0.0001). CONCLUSION: This study provides evidence of bariatric surgery's positive effect on serum T levels in obese men with baseline low T. Almost one out of two men with low T reached normal T levels after bariatric surgery. As the most comprehensive study to date, it validates and substantiates previous work suggesting that weight loss can improve T levels physiologically.

Artificial Intelligence Modeling and Priapism.

PURPOSE OF REVIEW: This narrative review aims to outline the current available evidence, challenges, and future perspectives of Artificial Intelligence (AI) in the diagnosis and management of priapism, a condition marked by prolonged and often painful erections that presents unique diagnostic and therapeutic challenges. RECENT FINDINGS: Recent advancements in AI offer promising solutions to face the challenges in diagnosing and treating priapism. AI models have demonstrated the potential to predict the need for surgical intervention and improve diagnostic accuracy. The integration of AI models into medical decision-making for priapism can also predict long-term consequences. AI is currently being implemented in urology to enhance diagnostics and treatment work-up for various conditions, including priapism. Traditional diagnostic approaches rely heavily on assessments based on history, leading to potential delays in treatment with possible long-term sequelae. To date, the role of AI in the management of priapism is understudied, yet to achieve dependable and effective models that can reliably assist physicians in making decisions regarding both diagnostic and treatment strategies.

Detection of microplastics in the human penis.

The proliferation of microplastics (MPs) represents a burgeoning environmental and health crisis. Measuring less than 5 mm in diameter, MPs have infiltrated atmospheric, freshwater, and terrestrial ecosystems, penetrating commonplace consumables like seafood, sea salt, and bottled beverages. Their size and surface area render them susceptible to chemical interactions with physiological fluids and tissues, raising bioaccumulation and toxicity concerns. Human exposure to MPs occurs through ingestion, inhalation, and dermal contact. To date, there is no direct evidence identifying MPs in penile tissue. The objective of this study was to assess for potential aggregation of MPs in penile tissue. Tissue samples were extracted from six individuals who underwent surgery for a multi-component inflatable penile prosthesis (IPP). Samples were obtained from the corpora using Adson forceps before corporotomy dilation and device implantation and placed into cleaned glassware. A control sample was collected and stored in a McKesson specimen plastic container. The tissue fractions were analyzed using the Agilent 8700 Laser Direct Infrared (LDIR) Chemical Imaging System (Agilent Technologies. Moreover, the morphology of the particles was investigated by a Zeiss Merlin Scanning Electron Microscope (SEM), complementing the detection range of LDIR to below 20 µm. MPs via LDIR were identified in 80% of the samples, ranging in size from 20-500 µm. Smaller particles down to 2 µm were detected via SEM. Seven types of MPs were found in the penile tissue, with polyethylene terephthalate (47.8%) and polypropylene (34.7%) being the most prevalent. The detection of MPs in penile tissue raises inquiries on the ramifications of environmental pollutants on sexual health. Our research adds a key dimension to the discussion on man-made pollutants, focusing on MPs in the male reproductive system.

Spontaneous erectile function recovery among young men with erectile dysfunction taking tadalafil 5 mg once a day.

BACKGROUND: Daily (once a day [OaD]) tadalafil intake is a valuable option for men favoring spontaneous over scheduled sexual intercourse. AIM: The study sought to assess the rate of and the clinical factors associated with spontaneous, medication-free erectile function (EF) recovery after discontinuation of tadalafil 5 mg OaD in a cohort of young men seeking first medical help for psychogenic erectile dysfunction (ED) as their primary complaint. METHODS: Data from 96 consecutive patients <50 years of age seeking first medical help for ED and prescribed tadalafil 5 mg OaD were analyzed. Patients completed the International Index of Erectile Function (IIEF) and underwent baseline penile color Doppler ultrasound. Follow-up involved clinical assessments or phone interviews. Spontaneous medication-free EF recovery was defined as IIEF EF domain score >22 after tadalafil discontinuation, prompting cessation of follow-up. Descriptive statistics compared tadalafil OaD responders and nonresponders. Cox regression hazard models explored the association between baseline characteristics and EF recovery risk post-drug discontinuation. Kaplan-Meier analyses estimated EF recovery probability over time. OUTCOMES: The primary outcome was EF recovery after discontinuation of tadalafil 5 mg OaD. RESULTS: Overall, median age was 39 (interquartile range [IQR], 32-45) years. Of all, 82 (85.4%) patients achieved EF recovery after tadalafil OaD discontinuation, while 14 (14.6%) patients were identified as nonresponders. Median tadalafil usage time (from beginning to discontinuation) was 3 (IQR, 2-11) months. The most common treatment-emergent adverse event was headache in 9 (9.4%) patients. Nonresponders were older (43 [IQR, 42-45] years vs 38 [IQR, 31-44] years; P = .03), had higher body mass index (25.5 [IQR, 23.4-29.9] kg/m2 vs 23.6 [IQR, 21.8-25.9] kg/m2; P = .04), and reported lower baseline IIEF EF domain scores (12 [IQR, 7-15] vs 15 [IQR, 10-22]; P = .02) than responders. Nonresponders and responders did not differ in terms of baseline ED severity, Charlson comorbidity index, smoking, alcohol consumption, regular physical exercise, and color Doppler ultrasound parameters. Upon Cox regression analysis, younger age (hazard ratio, 0.95; 95% confidence interval, 0.92-0.99; P = .01) was associated to EF recovery, after adjusting for baseline ED severity, body mass index, smoking, and Charlson comorbidity index ≥1. The Kaplan-Meier analysis displays the probability of EF recovery over time, indicating rates of 43%, 60%, and 72% at 3-, 6-, and 12-month follow-up intervals, respectively. CLINICAL IMPLICATIONS: Tadalafil 5 mg OaD is an effective short-term treatment for psychogenic ED, allowing its discontinuation after achieving a normal medication-free EF. STRENGTHS AND LIMITATIONS: The main limitations are the limited number of participants and the potential neglect of confounding factors. CONCLUSION: Almost 1 out of 2 young men with primary psychogenic ED who were prescribed with tadalafil 5 mg OaD recovered spontaneous medication-free EF after 3 months of treatment. Overall, the younger the patient was, the higher the chance there was of spontaneous EF recovery after drug discontinuation.

Study Protocol for a Randomized Controlled Trial of Low Intensity Shockwave Therapy for the Treatment of Post-Radical Prostatectomy Erectile Dysfunction: "SHARP-ED TRIAL".

Introduction: Erectile Dysfunction (ED) is a common challenge post Radical Prostatectomy (RALP), affecting men's sexual health after undergoing definitive cancer therapy. Despite employing nerve-sparing techniques, ED remains a prevalent issue in this population. Studies indicate that approximately 70%-85% of men experience varying degrees of ED following RALP. The existing treatment landscape for post-RALP-ED presents limitations, and a discernible knowledge gap persists. To address this, our study aims to investigate the efficacy of Shockwave Therapy (SWT) as a potential intervention for managing ED after RALP. Methods: This prospective, randomized, sham-controlled clinical trial aims to recruit 189 eligible patients post-RP and assess the effects of SWT. Comprehensive screening, including medical history, physical examinations, and biochemical evaluations, will be conducted to confirm eligibility. The intervention involves utilizing a device to administer focal shockwaves targeted at cavernosal tissue. Safety measures include continuous monitoring for adverse events and rigorous reporting protocols. The primary endpoint assesses changes in participants' ability to engage in penetrative intercourse from baseline to study completion, while secondary endpoints encompass various measures of erectile function, including questionnaire-based assessments, ultrasound parameters, and clinical outcomes. Results: Statistical analysis, encompassing ANOVA for continuous variables and Fisher's exact test for categorical ones, will evaluate demographic characteristics, baseline data, and primary as well as secondary outcomes for statistical significance. Detailed analysis of trends, subgroup comparisons, and treatment effects will provide a comprehensive understanding of the impact of SWT on post-RP ED. Conclusion: This study protocol represents a rigorous investigation into the potential therapeutic role of SWT in managing post-RP ED. The outcomes from this study aim to contribute valuable insights into the efficacy, safety, and potential improvements in erectile function following SWT, providing significant guidance for future interventions aimed at addressing this challenging condition affecting men's health and quality of life.

Does time of intraoperative exposure to the aerobiome increase microbial growth on inflatable penile prostheses?

Inflatable penile prosthesis (IPP) implantation is a surgical approach for the management of erectile dysfunction (ED). A feared complication is IPP infection, and increased operative time is a risk factor for infection. Exposure of an IPP implant to ambient air in the operating room (OR aerobiome) is thought to contribute to risk of infection from increased operative time, but this is not well-supported. The objective of this study was to evaluate if exposure to the OR aerobiome increased microbial colonization of IPPs. This was an ex vivo study using an uncoated IPP, observing standard surgical sterility and OR conditions. A sterile swab was collected every 30 min for 3 h from each IPP component. Positive controls consisted of swabs exposed to unprepped scrotal skin during in-office vasectomies. All swabs underwent quantitative polymerase chain reaction (qPCR) and next generation sequencing (NGS). Bioinformatic processing was carried out and taxonomic assignment was performed. No microbial growth was detected on any component of the IPPs at any time point, while positive control swabs all detected various skin flora, including bacterial and fungal growth. These findings suggest that exposure to the OR aerobiome does not increase the risk of IPP microbial colonization, at least within a 3-hour period. Further in vivo studies are needed.

Role of Follicle-stimulating Hormone, Inhibin B, and Anti-Müllerian Hormone in Predicting Sperm Retrieval from Men with Nonobstructive Azoospermia Undergoing Microdissection Testicular Sperm Extraction: A Systematic Review and Meta-analysis.

Background and objective: No clear-cut markers for predicting positive sperm retrieval (+SR) at microdissection testicular sperm extraction (mTESE) have been identified thus far. Our aim was to conduct a systematic review and meta-analysis to evaluate the ability of follicle-stimulating hormone (FSH), inhibin B (InhB), and anti-Müllerian hormone (AMH) to predict +SR in men with nonobstructive azoospermia (NOA) undergoing mTESE. Methods: We performed a search in the PubMed, EMBASE, Web of Science, and Scopus databases according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Thirty-four publications were selected for inclusion in the analysis. Key findings and limitations: Overall, the mean +SR rate was 45%. Pooled standardized mean difference (SMD) values revealed significant hormonal differences between the +SR and -SR groups, with lower FSH (SMD -0.30), higher InhB (SMD 0.54), and lower AMH (SMD -0.56) levels in the +SR group. Pooled odds ratios (Ors) revealed no significant prediction of +SR by either FSH (OR 1.03, 95% confidence interval [CI] 1.00-1.06) or InhB (OR 1.01, 95% CI 1.00-1.02), despite variations in baseline levels and study heterogeneity. Conversely, AMH had significant predictive value (OR 0.82, 95% CI 0.73-0.92), with lower baseline levels in the +SR group. InhB and FSH levels were higher in the +SR group, while InhB exhibited the opposite trend. Conclusions and clinical implications: Despite study heterogeneity, our meta-analysis findings support the ability of AMH to predict +SR for men with NOA undergoing mTESE. Patient summary: We conducted a review and analysis of results from previous studies. Our findings show that for men with an infertility condition called nonobstructive azoospermia, blood levels of anti-Müllerian hormone can predict successful extraction of sperm using a microsurgical technique. Levels of two other hormones did not predict successful sperm extraction.

Elevated periprostatic androgens, sneaky testosterone and its implications.

A subset of men with prostate cancer have elevated periprostatic androgens compared with levels in peripheral blood (termed the sneaky T phenomenon), which are associated with poor clinical outcomes after radical prostatectomy. These androgens are of testicular origin and reach the prostate, presumably through venous shunting. Varicocele physiology is accompanied by increased hydrostatic pressure within the pelvic venous system, providing a theoretical mechanistic explanation for the sneaky T phenomenon. These observations suggest a potential role for varicocele in contributing to prostate cancer pathophysiology through sneaky T, which if proved, could be a further indication for varicocele repair. Sneaky T can help to explain the differences in the natural history of benign or malignant prostatic diseases between individuals and could be a tool when deciding on the therapeutic course to take.

Top-cited articles in andrology journals from 2013-2022: a bibliometric analysis.

Bibliometric analyses serve to identify influential articles that have shaped medical practice and fostered new research ideas. Over the past decade, research in andrology has witnessed exponential growth, with an increasing number of academic publications, collaborations, and research innovations. However, there is a lack of literature that has identified the top-cited andrology articles. We conducted a bibliometric analysis to identify the top 1000 citations in andrology journals, with a focus on the top funding agencies, authors, institutions, countries/regions, and journals. To perform this analysis, we identified the top-cited articles in andrology journals as indexed in the Web of Science Core Collection. From 2013 through 2022, we found a total of 9827 articles published in andrology journals. The top publishers included "Andrology," the "Asian Journal of Andrology," and "Andrologia." The top affiliations contributing to research include the Cleveland Clinic Foundation (269 publications), Egyptian Knowledge Bank (EKB) (265), and Shanghai Jiao Tong University (202). Funding was primarily provided by notable agencies such as the National Natural Science Foundation of China (905 grants), United States Department of Health Human Services (321), and National Institutes of Health (NIH USA) (317). The present bibliometric analysis highlights andrology research from 2013 through 2022, offering key insights into leading contributors, influential authors, prominent funding sources, and major trends in the field.

Eligibility for the medical therapy among men with non-obstructive azoospermia-Findings from a multi-centric cross-sectional study.

BACKGROUND: Existing literature does not provide accurate epidemiological data regarding the true prevalence of men with non-obstructive azoospermia (NOA) who would be eligible for hormonal optimization therapy, according to specific pre-treatment criteria. OBJECTIVES: To investigate the characteristics of those men with NOA who would qualify for the medical therapy prior to any SR procedure in a large multi-centric cross-sectional study. MATERIALS AND METHODS: Complete data from 1644 NOA patients seeking medical help for primary infertility at three tertiary referral centers from USA, Brazil, and Italy were analyzed. Baseline serum hormone levels were collected for all patients. NOA was confirmed after two consecutive semen analyses. Genetic tests, including karyotype analysis and Y microdeletions, were performed on all patients. Patients with secondary hypogonadism (total testosterone (T) levels less than 300 ng/dL and luteinizing hormone (LH) levels less than 8 mIU/mL) were earmarked as potential candidates for receiving clomiphene citrate (CC) and/or human chorionic gonadotropin (hCG). Patients with a T to 17ß-estradiol (E2) ratio < 10 were classified as eligible for aromatase inhibitors (AIs) therapy (e.g., anastrazole). A third sub-cohort was created by combining the criteria of the first two sub-cohorts. Descriptive statistics was used to detail overall characteristics and differences between the different sub-cohorts. RESULTS: Among the 1,644 men, 28% (n = 460) had T < 300 ng/dL and LH < 8 mIU/mL, thereby being potentially suitable for CC and/or hCG, while 37% (n = 607) had a T to E2 ratio < 10 thus potentially suitable for AIs. Lastly, 17.7% (n = 280) met the criteria for potential eligibility for both CC and/or hCG and AIs. CONCLUSIONS: Findings from this multicentric cross-sectional study reveal that about 30% of men with NOA were eligible for hormonal treatment with CC and/or hCG while 37% were found to be potential candidates for AIs, and 17% for both therapies. Therefore, these findings show that a only a small subset of NOA patients can benefit from medical therapy prior to considering any SR procedures.

Can we improve time to patency with vasoepididymostomy with an innovative epididymal occlusion stitch?

INTRODUCTION: Obstructive azoospermia occurs when there is a blockage in the male reproductive tract, leading to a complete absence of sperm in the ejaculate. It constitutes around 40% of all cases of azoospermia (1, 2). Blockages in the male reproductive tract can arise from either congenital or acquired factors, affecting various segments such as the epididymis, vas deferens, and ejaculatory ducts (3). Examples of congenital causes encompass conditions like congenital bilateral absence of the vas deferens and unexplained epididymal blockages (4). Acquired instances of obstructive azoospermia may result from factors like vasectomy, infections, trauma, or unintentional injuries caused by medical procedures (5). This complex condition affecting male fertility, presents two main treatment options: microsurgical reconstruction and surgical extraction of sperm followed by in vitro fertilization (IVF). Microsurgical reconstruction proves to be the most cost-effective option for treating obstructive azoospermia when compared with assisted reproductive techniques (6, 7). However, success rates of reconstruction defined by patency are as high as 99% for vasovasostomy (VV) but decline to around 65% if vasoepididymostomy (VE) is required (8, 9). Thus, continued refinement in technique is necessary in order to attempt to improve patency for patients undergoing VE. In this video, we show a comprehensive demonstration of microsurgical VE, highlighting the innovative epididymal occlusion stitch. The goal of this innovative surgical technique is to improve outcomes for VE. MATERIALS AND METHODS: The patient is a 39-year-old male diagnosed with obstructive azoospermia who presents for surgical reconstruction via VE. His partner is a 37-years-old female with regular menstrual cycles. The comprehensive clinical data encompasses a range of factors, including FSH levels, results from semen analysis, and outcomes from testicular sperm aspiration. This thorough exploration aims to provide a thorough understanding of our innovative surgical technique and its application in addressing complex cases of obstructive azoospermia. RESULTS: The procedure was started on the right, the vas deferens was identified and transected. The abdominal side of the vas was intubated and a vasogram performed, there was no obstruction. There was no fluid visible from the testicular side of the vas for analysis, thus we proceeded with VE. Upon inspection of the epididymis dilated tubules were identified. After selecting a tubule for VE, two 10-0 nylon sutures were placed, and it was incised. Upon inspection of the fluid motile sperm was identified. After VE, we performed a novel epididymal occlusion stitch technique. This was completed distal to the anastomosis by placing a 7-0 prolene through the tunica of the epididymis from the medial to lateral side. This stitch was then tightened down with the goal to largely occlude the epididymis so that sperm will preferentially travel through the anastomosis. The steps were then repeated on the left. At 3-month follow up, the patient had no change in testicular size as compared with preoperative size (18cc), he had no testicular or incisional discomfort, and on semen analysis he had presence of motile sperm. After 3 months post-surgery, the patient had motile sperm seen on semen analysis. DISCUSSION: The introduction of a novel epididymal occlusion stitch demonstrates a targeted strategy to enhance the success of microscopic VE. Encouragingly, a 3-month post-surgery follow-up reveals the presence of motile sperm, reinforcing the potential efficacy of our approach. This is promising given the historical lower patency, delayed time to patency, and higher delayed failure rates that patients who require VE experience (10). In total, 40% of all azoospermia cases can be attributed to obstruction. The conventional treatments for obstructive azoospermia involve microsurgical reconstruction and surgical sperm retrieval followed by IVF. While microsurgical reconstruction has proven to be economically viable, the quest for enhanced success rates has led to the exploration of innovative techniques. Historically, the evolution of VV and VE procedures, initially performed in the early 20th century, laid the foundation for contemporary microsurgical approaches (11). Notably, the microscopic VV demonstrated significant improvements in patency rates and natural pregnancy likelihood, as evidenced by the seminal Vasovastomy Study Group study in 1991 (8). In contemporary literature, success rates particularly for VE remain unchanged for the past three decades since the original published success rates by the Vasectomy Reversal Study Group (12). VE is associated with a longer time to patency as well with patients taking 2.8 to 6.6 months to have sperm return to ejaculate as compared to 1.7 to 4.3 months for those undergoing VV. Additionally, of those patients who successfully have sperm return to the ejaculate after VE up to 50% will have delayed failure compared to 12% for those undergoing VV who are patent. Finally, of those who experience delayed failure after undergoing VE it usually occurs earlier with studies reporting as early as 6 months post-operatively (10). Given the lack of improvement and significantly worsened outcomes with VE further surgical refinement is a constant goal for surgeons performing this procedure. CONCLUSION: In conclusion, this video is both a demonstration and a call to action for commitment to surgical innovation. We aim to raise the bar in VE success rates, ultimately bringing tangible benefits to patients and contributing to the ongoing evolution of reproductive medicine. The novel epididymal occlusion stitch emerges as a beacon of progress, promising not only enhanced safety but also potential reductions in patency time. Surgical excellence and methodological refinement, as exemplified in this video, lay the foundation for a future where male reproductive surgery continues to break new ground.

Antioxidant Supplementation for Erectile Dysfunction: Systematic Review and Meta-Analysis of Double-Blind, Randomized, Placebo-Controlled Trials.

PURPOSE: This meta-analysis aimed to determine the efficacy and safety of antioxidant supplementation for treating erectile dysfunction (ED). MATERIALS AND METHODS: We systematically searched MEDLINE, Embase, and the Cochrane Library for double-blind, randomized, placebo-controlled trials of oral antioxidant supplementation in men with ED. Erectile function was assessed by the International Index of Erectile Function-Erectile Function domain (IIEF-EF) score. Using random-effects meta-analysis models, antioxidant and placebo groups were compared for erectile function using the mean difference in IIEF-EF score adjusted to a 6-30 scale and for side effects using the log risk ratio. RESULTS: The review included 23 trials of 1,583 men (median age 51 years) treated with antioxidant supplementation or placebo for a median of 12 weeks (range, 4 weeks to 6 months). Antioxidant supplementation significantly improved erectile function compared to placebo, with a mean difference of 5.5 points (95% confidence interval [CI]: 3.7 to 7.3; p<0.001) on the IIEF-EF. In meta-regression, the treatment benefit was greater in men with more severe ED (p<0.001). Side effects were uncommon, none were serious, and the frequency was comparable between antioxidant (3.8%) and placebo (2.1%) groups (log risk ratio=0.36; 95% CI: -0.24 to 0.97; p=0.24). CONCLUSIONS: Antioxidant supplementation appears safe and significantly improves erectile function in men with ED, particularly those with more severe symptoms. Limitations of this review included unknown long-term efficacy and safety and the inability to make specific product and dosing recommendations due to the variety of antioxidants and regimens studied.

Long-term impact of commonly performed operations in pediatric urology on reproductive and sexual health.

Introduction: Sexual dysfunction is highly prevalent among men of reproductive age. Clinical practice guidelines have been established to assist providers in identification and education of patients who are at increased risk for infertility and sexual dysfunction with certain congenital and acquired urogenital disorders. The authors sought to review the reproductive and sexual health implications of treating common childhood urological conditions with commonly performed surgical procedures. Methods: To ensure the inclusion of influential and highly regarded research, we prioritized citations from the most-frequently cited articles on our respective review topics. Our inclusion criteria considered studies with substantial sample sizes and rigorously designed methodologies. Several topics were reviewed, including penile chordee, hypospadias, posterior urethral valves, varicoceles, undescended testicles, and testicular torsion. Results: For chordee, surgical plication or corporal grafting may be employed. Erectile function remains unaltered post-surgery, while penile length may decrease after repair, which may be avoided using dermal grafts. Hypospadias repair hinges on severity and availability of the urethral plate. Those who underwent hypospadias repair report decreased penile length, but sexual satisfaction, libido, and semen quality are comparable to controls. Posterior urethral valves are usually treated with valve ablation. While valve ablation and bladder neck incision have not been found to affect ejaculatory function, high degree of concurrent renal dysfunction related to nephrogenic and bladder dysfunction may impact semen parameters and erectile function. Regarding varicocele, earlier management has been associated with better long-term fertility outcomes, and surgical intervention is advisable if there is observable testicular atrophy. Earlier repair of undescended testicle with orchiopexy has been found to improve fertility rates as well as decrease malignancy rates. Unilateral orchiectomy for testicular torsion without the ability for salvage has been shown to have decreased semen parameters but unaffected fertility rates. Conclusion: Infertility and sexual dysfunction are multivariable entities, with etiologies both congenital and acquired. At the same time, many common pediatric urology surgeries are performed to correct anatomic pathology that may lead to reproductive dysfunction in adulthood. This review highlights the need for diagnosis and management of pediatric urologic conditions as these conditions may impact long-term sexual function post-operatively.

Long-term impact of commonly performed operations in pediatric urology on sexual health Many men of reproductive age face sexual health challenges, prompting the creation of guidelines for identifying and addressing issues related to urogenital disorders. This study explores the impacts of common surgical procedures on reproductive and sexual health in children with urological conditions. By reviewing extensive literature, the study focuses on the long-term effects of pediatric urologic surgeries, emphasizing influential and frequently cited research for a comprehensive understanding. For conditions like chordee, surgical options such as plication or grafting may be considered. While erectile function typically remains unchanged, there might be a decrease in penile length post-surgery, which can be addressed with specific techniques. Hypospadias repair varies based on severity, with those undergoing the procedure having shorter penises. However, their sexual satisfaction, libido, and semen quality are comparable to others. Treatment of posterior urethral valves (PUV) often involves valve ablation, however some studies have shown altered semen parameters following ablation. Managing varicocele early on leads to better outcomes, and surgery is recommended if testicular atrophy is observed. Orchiopexy and orchiectomy are procedures for undescended testis (UDT) and testicular torsion in children. Pediatric urologic diseases and their surgical interventions can significantly affect sexual function and fertility in adulthood due to their multifactorial nature. While some procedures aim to preserve or enhance sexual potential such as proper urethral development, others may inadvertently impact sexual health negatively, such as necrotic testes removal. This underscores the importance of thorough diagnosis and management of pediatric urologic conditions to safeguard long-term sexual function post-surgery.

Prospective Patient Preferences for Humor in Urologists Treating Erectile Dysfunction: A Survey Study.

INTRODUCTION: Men seeking treatment for sexual dysfunction can experience embarrassment as a result of stigma. This research manuscript presents the findings of a survey conducted to investigate the influence of humor on prospective patients' preferences when selecting a specialist to address erectile dysfunction (ED). METHODS: The respondents were presented with five pairs of mock urology business cards: one professional and one humorous. A questionnaire was designed and distributed via an online survey platform. Descriptive statistics and Fisher's exact test were performed using the Statistical Package for Social Sciences (SPSS) software version 29 (IBM SPSS Statistics, Armonk, NY) to evaluate age and race associations with card preference. RESULTS: Among the 997 participants, an average of 66.1% (a median of 71.2%) preferred professional cards. Humorous card selection rates ranged from 5.2% to 38.4% compared to 54.0% to 78.1% for professional cards. A statistically significant relationship between age and professional card choice existed in all except the fifth set of cards (p = 0.001, 0.001, 0.001, 0.001, and 0.054). The relationship between race or ethnicity and business card preference was not reported due to an imbalance in demographics, with most participants identifying as Caucasian. DISCUSSION: A humor-centric approach may not resonate with all individuals seeking treatment for sensitive conditions such as ED. Limitations include the subjectivity of humor, the use of an online survey platform, and the hypothetical nature of this study. Real patients experiencing ED may face stigma and respond to humor differently. CONCLUSION: This study provides insights into patient preference for professionalism over humor from their urologist but leaves room for the exploration of humor in medical contexts.
