RESUMO
PURPOSE: Our goal was to characterize the distribution of follicle stimulating hormone (FSH) in fertile and subfertile nonazoospermic men, and to determine the ability of various FSH thresholds to predict fertility status. MATERIALS AND METHODS: We performed a retrospective cohort study of 1389 nonazoospermic men who presented for fertility evaluation. Men with at least 2 semen analyses and 1 FSH level were included. Men were dichotomized into fertile and subfertile groups based on total motile sperm count. FSH was evaluated within a multivariable model, and positive predictive values (PPVs) for subfertility were used to assess the clinical utility of various FSH thresholds. RESULTS: One thousand fifteen (80%) men were classified as fertile and 274 (20%) as subfertile. Age, presence of varicocele, and testosterone levels were not statistically different between the groups. Median FSH was 4.0 vs 6.0 (P < .001) among fertile vs subfertile men. Multiple FSH thresholds ranging from 2.9 to 9.3 performed similarly in predicting fertility status (PPV 0.49-0.59). Only FSH thresholds above the 95th percentile (12.1) had PPVs greater than 0.7. The highest PPV (0.84) was seen at an FSH of 20.8 (99th percentile). CONCLUSIONS: While there were significant differences in FSH levels among fertile and subfertile nonazoospermic men, multiple FSH cutoffs between 2.2 and 9.3 performed poorly for prediction of fertility status as determined by total motile sperm count. It was not until the 95th percentile FSH value that a clinically useful level of predictability for subfertility was reached, indicating that FSH should not be used as a standalone test of fertility status. Nonetheless, FSH testing remains clinically useful and may be most informative in the setting of extreme values or discordant FSH and semen analysis results.

BACKGROUND AND OBJECTIVE: Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. METHODS: We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN. Length of stay (LOS), complications, emergency department (ED) visits, and readmissions were evaluated between men with and without hypogonadism at the time of surgery. Subgroup analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS: Among 13 598 men who underwent RN, 972 (7.1%) had hypogonadism. Men with hypogonadism were more frail compared to men without hypogonadism (HFRS: median: 8.2, interquartile range [IQR]: 5.2-11.7 vs. median: 7.0, IQR: 4.3-10.7, p < 0.001) and had increased incidence of postoperative ileus (13.0% vs. 10.8%, p = 0.045), acute kidney injury (25.5% vs. 21.6% p = 0.005), and cardiac arrest (1.2% vs. 0.6%, p = 0.034). Hypogonadism was not associated with LOS, 90-day ED visit or readmission. However, high-risk frailty was associated with increased risk of 90-day ED visit (hazard ratio [HR]: 2.1, 95% confidence interval [95% CI]: 1.9-2.4, p < 0.001) and 90-day inpatient readmission (HR: 2.6, 95% CI: 2.2-3.1, p < 0.001), compared to low-risk frailty patients. Among men with hypogonadism, TRT was not associated with any postoperative outcomes. CONCLUSIONS: Hypogonadism and frailty should be considered in the preoperative evaluation for men undergoing RN as risk factors for adverse postoperative outcomes.

PURPOSE: To better understand the effects of aging, metabolic syndrome, diurnal variation, and seasonal variation on serum testosterone levels in the context of current guideline statements on testosterone deficiency. METHODS: This cross-sectional study utilized the United Kingdom Biobank. Physical examination, anthropomorphic measurements, and laboratory evaluation were performed at the time of enrollment from 2006 to 2010. The primary outcomes were the effect of age, the presence of metabolic syndrome, the time of day, and the month of the year on serum testosterone levels. RESULTS: Among 197,883 included men, the 5th, 25th, 50th, 75th and 95th percentile testosterone levels in men without metabolic syndrome were significantly higher than those in men with metabolic syndrome at every decade of life (p < 0.001). The average testosterone level within each group (men without metabolic syndrome vs. men with) was clinically similar across decade of life (12.43 in 40's 12.29 in 50's 12.24 in 60's vs. 10.69 in 40's 10.56 in 50's 10.63 in 60's respectively). Average testosterone levels decreased with blood draws later in the day ranging from 10.91 to 12.74 nmol/L (p < 0.01). Similarly, there was seasonal variation in serum testosterone ranging from 11.86 to 12.18 nmol/L (p < 0.01). CONCLUSIONS: We found significant variation in serum testosterone according to the presence of metabolic syndrome and time of laboratory draw, but not according to age. These data challenge the prior dogma of age-related hypogonadism and favor an individualized approach towards serum testosterone measurement and interpretation. However, further studies are needed to correlate these population-based data with individuals' hypogonadal symptoms.
RESUMO
BACKGROUND: Most radical prostatectomies are completed with robotic assistance. While studies have previously evaluated perioperative outcomes of robot-assisted radical prostatectomy (RARP), this study investigates disparities in access and clinical outcomes of RARP. STUDY DESIGN: The National Cancer Database (NCDB) was used to identify patients who received radical prostatectomy for cancer between 2010 and 2017 with outcomes through 2018. RARP was compared to open radical prostatectomy (ORP). Odds of receiving RARP were evaluated while adjusting for covariates. Overall survival was evaluated using a propensity-score matched cohort. RESULTS: Overall, 354 752 patients were included with 297 676 (83.9%) receiving RARP. Patients who were non-Hispanic Black (82.8%) or Hispanic (81.3%) had lower rates of RARP than non-Hispanic White (84.0%) or Asian patients (87.7%, p < 0.001). Medicaid or uninsured patients were less likely to receive RARP (75.5%) compared to patients with Medicare or private insurance (84.4%, p < 0.001). Medicaid or uninsured status was associated with decreased odds of RARP in adjusted multivariable analysis (OR 0.61, 95% CI 0.49-0.76). RARP was associated with decreased perioperative mortality and improved overall survival compared to ORP. CONCLUSION: Patients who were underinsured were less likely to receive RARP. Improved access to RARP may lead to decreased disparities in perioperative outcomes for prostate cancer.

PURPOSE OF REVIEW: The COVID-19 pandemic has led to devastating health outcomes across the world. Initially thought to primarily affect the respiratory system, there is now clear and abundant evidence that COVID-19 can impact upon the male genitourinary system and overall men's health. In this review article, we explore the potential mechanisms by which COVID-19 specifically affects men and we review the literature examining the adverse effects of the disease on men's health. RECENT FINDINGS: Studies suggest that men are at higher risk for severe COVID-19 infection and death. COVID-19 infection has a negative impact on men's health including worsening semen parameters, potentially lower testosterone levels, and an increased risk of erectile dysfunction. SUMMARY: COVID-19 is a highly pathogenic virus that exerts adverse effects upon the male genitourinary system in myriad ways. The COVID-19 infection can impact serum testosterone, fertility, sexual function, and mental health. Fortunately, the COVID-19 vaccine is safe and effective in preventing COVID-19 infection and many of these sequelae.

This study examined the relationship between stimulant medications used for the treatment of attention deficit hyperactivity disorder and semen parameters. We performed a retrospective cohort study at a large, academic institution between 2002 and 2020. We included men with a semen analysis without prior spermatotoxic medication use, empiric medical therapy exposure or confounding medical diagnoses (varicocele, Klinefelter's syndrome, cryptorchidism, cystic fibrosis, diabetes, cancer or cancer-related treatment, and azoospermia). Men were stratified by stimulant exposure (methylphenidate or amphetamines). A multivariable linear regression was fit to assess the association between individual semen parameters, age, stimulant exposure and non-stimulant medication use. Of 8,861 men identified, 106 men had active prescriptions for stimulants within 90 days prior to semen testing. After controlling for age and exposure to non-stimulant medications, stimulant use was associated with decreased total motile sperm count (ß: -18.00 mil/ejaculate and standard error: 8.44, p = 0.033) in the setting of decreased semen volume (ß: -0.35 ml, and standard error: 0.16, p = 0.035), but not sperm concentration, motility and morphology. These findings suggest a role for reproductive physicians and mental health providers to consider counselling men on the potential negative impact of stimulants prescribed for attention deficit hyperactivity disorder on semen volume during fertility planning.

We aimed to characterise diverse practice patterns for vasal reconstruction and to determine whether surgeon volume is associated with vasoepididymostomy performance at the time of reconstruction. We identified adult men who underwent vasal reconstruction from 2000 to 2020 in Premier Healthcare Database and determined patient, surgeon, cost and hospital characteristics for each procedure. We identified 3,494 men who underwent either vasovasostomy-alone (N = 2,595, 74.3%) or any-vasoepididymostomy (N = 899, 25.7%). The majority of providers (N = 487, 88.1%) performed only-vasovasostomy, 10 (1.8%) providers performed only-vasoepididymostomy and 56 (10.1%) providers performed both. Median total hospital charge of vasoepididymostomy was significantly higher than vasovasostomy ($39,163, interquartile range [IQR]$11,854-53,614 and $17,201, IQR$10,904-29,986, respectively). On multivariable regression, men who underwent procedures at nonacademic centres (OR 2.71, 95% CI 2.12-3.49) with higher volume surgeons (OR 11.60, 95% CI 8.65-16.00) were more likely to undergo vasoepididymostomy. Furthermore, men who underwent vasoepididymostomy were more likely to self-pay (OR 2.35, 95% CI 1.83-3.04, p < .001) and more likely had procedures in the Midwest or West region (OR 2.22, 95% CI 1.66-2.96 and OR 2.11, 95% CI 1.61-2.76, respectively; p < .001). High-volume providers have increased odds of performing vasoepididymostomy at the time of reconstruction but at a significantly higher cost. These data suggest possibly centralising reconstructive procedures among high-volume providers.

PURPOSE: We examined the relationship of the serum testosterone level to low fat, Mediterranean and low carbohydrate diets in a large, nationally representative patient sample. MATERIALS AND METHODS: We queried the NHANES (National Health and Nutrition Examination Survey) from 1999 to 2000, 2003 to 2004 and 2011 to 2012. Men 18 to 80 years old who completed the 2-day dietary history and underwent serum testosterone testing were included in analysis. Diets were categorized as low fat, Mediterranean, low carbohydrate or nonrestrictive. Multivariable modeling was used to determine the relationship between diet and serum testosterone. RESULTS: Of the 3,128 men who met study inclusion criteria 457 (14.6%) and 764 (24.4%) met the criteria for a low fat and a Mediterranean diet, respectively. Only 2 men (less than 0.1%) met the criteria for a low carbohydrate diet, which was removed from further analysis. Mean ± SD serum testosterone was 435.5 ± 6.7 ng/dl. Mean testosterone was lower among men with a low fat diet (410.8 ± 8.1 vs 443.5 ± 7.3, p=0.005) and a Mediterranean diet (412.9 ± 9.1 vs 443.5 ± 7.3, p=0.002). Multivariable analysis controlling for age, body mass index, activity level, diabetes, comorbidities and prostate cancer showed that men with a nonrestrictive diet had higher serum testosterone than those adhering to a low fat diet (ß -57.2, 95% CI -105.6 to -8.8, p <0.05). CONCLUSIONS: Men adhering to low fat diets had lower serum testosterone levels even when controlling for comorbidities, age, body mass index and activity levels. As differences in serum testosterone between the diets were modest, the avoidance of fat restrictive diets should be weighed against the potential benefits on an individual basis.

Recent data have suggested that short-term NSAID use induces a state of compensated hypogonadism. Our aim was to investigate the association between chronic, regular NSAID use and compensated hypogonadism in a large, nationally representative cohort, the US National Health and Nutrition Examination Survey (NHANES) database. Men 20-80 years who answered the analgesic use questionnaire and underwent hormonal testing were included. Multivariable regression was utilised to determine the relationship between NSAID use and serum testosterone (T), anti-Mullerian hormone (AMH) and T:AMH ratio. Among 3,749 men, 505 (13.5%) reported regular NSAID use and 3,244 (86.5%) did not. Regular users had lower T (440.7 ± 27.0 vs. 557.0 ± 24.9 ng/dl, p = .005) and albumin (43.8 ± 0.2 vs. 45.1 ± 0.1, p < .001) compared to nonregular users. On multivariable analysis, only active smoking was significantly associated with T, AMH and T:AMH ratio (p < .001, p = .036 and p = .005 respectively). Regular NSAID use was not associated with T, AMH or T:AMH ratio (p = .523, p = .974, and p = .872 respectively). In this nationally representative sample of US men, regular and chronic NSAID use was not associated with alterations in T or compensated hypogonadism. These data should reassure patients and clinicians regarding the safety of NSAID use with respect to the risk of alteration in the hypothalamic-pituitary-gonadal axis.

PURPOSE: The rise in opioid related deaths and addiction has been linked to physician prescribing. Opioids are commonly prescribed to patients with renal colic due to nephrolithiasis. The aim of this study was to describe the relationship between nephrolithiasis and opioid use in the United States. MATERIALS AND METHODS: Using the NHANES (National Health and Nutrition Examination Survey) we analyzed the relationship between a self-reported history of kidney stones and current opioid use in a nationally representative sample. RESULTS: Current opioid use was significantly greater among those who did vs did not report a history of kidney stones (10.9%, 95% CI 9.1-12.9 vs 6.1%, 95% CI 5.4-6.8). The prevalence of opioid use increased with the number of kidney stones passed, reaching 13.7% (95% CI 11.1-16.9) in subjects who had passed 2 or more stones (p <0.001). On multivariable logistic regression analysis adjusting for age, gender, smoking status, number of health care visits in the last year and comorbid conditions nephrolithiasis was independently associated with opioid based medication use (OR 1.27, 95% CI 1.07-1.49, p = 0.006). CONCLUSIONS: The association between a history of kidney stones and current narcotic use suggests that nephrolithiasis may be a risk factor for long-term opioid use. While this study is limited by the cross-sectional design and the absence of detailed stone histories, it adds to the evidence that altering pain management strategies may be beneficial in this population.

PURPOSE: Inflatable penile prostheses and artificial urinary sphincters are used to treat men with erectile dysfunction and stress urinary incontinence, respectively. After prostate cancer treatment men often experience erectile dysfunction and stress urinary incontinence. Dual prosthetic implantation can improve the quality of life of these men. We evaluated reoperation outcomes in men who underwent dual implantation compared to each device implanted individually. MATERIALS AND METHODS: We queried the SPARCS (New York State Department of Health Statewide Planning and Research Cooperative) database for men who underwent inflatable penile prosthesis and/or artificial urinary sphincter insertion between 2000 and 2014. The primary outcomes were the inflatable penile prosthesis and artificial urinary sphincter reoperation rates (revision, replacement or removal). Multivariable regression analysis was performed to assess the association of dual implantation with reoperation. Adjusted time to event analysis was also performed. RESULTS: Median followup in the inflatable penile prosthesis cohort was 66 months (IQR 25-118) and in the artificial urinary sphincter cohort it was 69 months (IQR 27-121). Compared with men who received a penile prosthesis alone those with a penile prosthesis and an artificial urinary sphincter had a higher likelihood of undergoing inflatable penile prosthesis reoperation at 1 year (OR 2.08, 95% CI 1.32-3.27, p <0.01) and 3 years (OR 2.60, 95% CI 1.69-3.99, p <0.01). Compared with an artificial urinary sphincter alone patients with an inflatable penile prosthesis and an artificial urinary sphincter did not have a higher likelihood of undergoing artificial urinary sphincter reoperation at 1 year (p = 0.76) or 3 years (p = 0.73). CONCLUSIONS: Combined inflatable penile prosthesis and artificial urinary sphincter insertion portends a higher likelihood of inflatable penile prosthesis reoperation at 1 and 3 years. However, artificial urinary sphincter outcomes remain comparable. These findings should be used to better counsel patients about the risk of reoperation when undergoing dual implantation.

PURPOSE: Recent years have brought many changes in the management of localized prostate cancer as national screening guidelines have been updated and diagnostic practice patterns evolved. We sought to better understand how the changing landscape influenced treatment utilization in the United States. METHODS: We used the SEER database in this retrospective analysis of patients with clinically localized prostate cancer between 2004 and 2013. We evaluated utilization of primary treatment modalities over time with descriptive and trend analyses, and examined treatment utilization by cancer risk group and age at diagnosis. RESULTS: Of 398 074 patients in the analytic data set, 38% elected radiation therapy, 38% underwent radical prostatectomy, and 24% opted for expectant management. While in 2004 radiation treatment was almost twice as common as expectant management (42% vs 23%), by 2013 approximately equal percentages of patients were treated with each of the three modalities. Expectant management use increased over time, while the proportion of patients opting for surgery decreased remarkably with increasing age at diagnosis in intermediate- and higher-risk disease. Among radiotherapy options, brachytherapy was most common among lower-risk patients in 2004 but substantially decreased over time (P < 0.001). CONCLUSIONS: Management of localized prostate cancer changed substantially over time in the United States. Utilization of expectant management has increased for men with low- and intermediate risk cancer. Among those who pursue curative therapy, younger men remain more likely to elect surgery whereas older men tend to choose radiotherapy. Further studies are needed to better characterize factors contributing to treatment selection.

PURPOSE: Guidelines from the NCCN® (National Comprehensive Cancer Network®) advocate digital rectal examination screening only in men with elevated prostate specific antigen. We investigated the effect of prostate specific antigen on the association of digital rectal examination and clinically significant prostate cancer in a large American cohort. MATERIALS AND METHODS: We evaluated the records of the 35,350 men who underwent digital rectal examination in the screening arm of the Prostate, Lung, Colorectal and Ovarian Cancer Screening trial for the development of clinically significant prostate cancer (Gleason 7 or greater). Followup was 343,273 person-years. The primary outcome was the rate of clinically significant prostate cancer among men with vs without suspicious digital rectal examination. We performed competing risks regression to evaluate the interaction between time varying suspicious digital rectal examination and prostate specific antigen. RESULTS: A total of 1,713 clinically significant prostate cancers were detected with a 10-year cumulative incidence of 5.9% (95% CI 5.6-6.2). Higher risk was seen for suspicious vs nonsuspicious digital rectal examination. Increases in absolute risk were small and clinically irrelevant for normal (less than 2 ng/ml) prostate specific antigen (1.5% vs 0.7% risk of clinically significant prostate cancer at 10 years), clinically relevant for elevated (3 ng/ml or greater) prostate specific antigen (23.0% vs 13.7%) and modestly clinically relevant for equivocal (2 to 3 ng/ml) prostate specific antigen (6.5% vs 3.5%). CONCLUSIONS: Digital rectal examination demonstrated prognostic usefulness when prostate specific antigen was greater than 3 ng/ml, limited usefulness for less than 2 ng/ml and marginal usefulness for 2 to 3 ng/ml. These findings support the restriction of digital rectal examination to men with higher prostate specific antigen as a reflex test to improve specificity. It should not be used as a primary screening modality to improve sensitivity.

PURPOSE: We sought to determine the association between multiple regions of interest on prebiopsy magnetic resonance imaging and the detection of clinically significant prostate cancer in men undergoing magnetic resonance imaging-ultrasound fusion biopsy. MATERIALS AND METHODS: We performed a retrospective, single institution analysis of men who underwent fusion biopsy. Men with prior positive biopsies, magnetic resonance imaging performed elsewhere and/or magnetic resonance imaging prior to release of the PI-RADS™ (Prostate Imaging Reporting and Data System) version 2 were excluded from study, resulting in 381 participants. Modeled independent variables included patient age, number of regions of interest with a PI-RADS categorization of 3 or greater, body mass index, prostate specific antigen, prostate volume and PI-RADS categorization. Multivariable logistic regression was performed to determine factors associated with finding clinically significant prostate cancer (Gleason 7 or greater) on biopsy. RESULTS: Median age was 67.2 years (IQR (61.6-73.0) and median prostate specific antigen was 6.6 ng/ml (5.0-10.0). Adjusted analysis demonstrated that age (OR 1.10, 95% CI 1.06-1.15, p ≤0.001), body mass index (OR 1.08, 95% CI 1.01-1.16, p = 0.038) and prostate specific antigen (OR 1.06, 95% CI 1.01-1.10, p = 0.015) were associated with detection of clinically significant prostate cancer. PI-RADS categories 4 (OR 4.62, 95% CI 2.23-9.33) and 5 (OR 6.75, 95% CI 2.72-16.71, each p <0.001) were associated with greater odds of clinically significant prostate cancer. Multiple regions of interest were not associated with the detection of clinically significant prostate cancer (OR 1.05, 95% CI 0.60-1.84, p = 0.857). CONCLUSIONS: Multiple regions of interest do not portend a greater likelihood of finding clinically significant prostate cancer. Physicians should recognize that multiple regions of interest should not influence the decision to perform fusion biopsy. Our findings may ease patient anxiety concerning these findings.

PURPOSE: The incidence of localized prostate cancer has decreased with shifts in prostate cancer screening. While recent population based studies demonstrated a stable incidence of locoregional prostate cancer, they categorized organ confined, extraprostatic and lymph node positive disease together. However, to our knowledge the contemporary incidence of prostate cancer with pelvic lymph node metastases remains unknown. MATERIALS AND METHODS: We used SEER (Surveillance, Epidemiology and End Results) data from 2004 to 2014 to identify men diagnosed with prostate cancer. We analyzed trends in the age standardized prostate cancer incidence by stage. The impact of disease extent on mortality was assessed by adjusted Cox proportional hazard analysis. RESULTS: During the study period the annual incidence of nonmetastatic prostate cancer decreased from 5,119.1 to 2,931.9 per million men (IR 0.57, 95% CI 0.56-0.58, p <0.01) while the incidence of pelvic lymph node metastases increased from 54.1 to 79.5 per million men (IR 1.47, 95% CI 1.33-1.62, p <0.01). The incidence of distant metastases in men 75 years old or older reached a nadir in 2011 compared to 2004 (IR 0.81, 95% CI 0.74-0.90, p <0.01) and it increased in 2012 compared to 2011 (IR 1.13, 95% CI 1.02-1.24, p <0.05). The risk of cancer specific mortality significantly increased in men diagnosed with pelvic lymph node metastases (HR 4.5, 95% CI 4.2-4.9, p <0.01) and distant metastases (HR 21.9, 95% CI 21.2-22.7, p <0.01) compared to men with nonmetastatic disease. CONCLUSIONS: The incidence of pelvic lymph node metastases is increasing coincident with a decline in the detection of localized disease. Whether this portends an increase in the burden of advanced disease or simply reflects decreased lead time remains unclear. However, this should be monitored closely as the increase in N1 disease reflects an increase in incurable prostate cancer at diagnosis.

PURPOSE: Uptake of active surveillance and changes in prostate cancer care may affect the utilization of and complications following prostate needle biopsy. We characterized recent trends and risk factors for prostate needle biopsy complications using a statewide, all-payer cohort. MATERIALS AND METHODS: We used SPARCS (New York Statewide Planning and Research Cooperative System) to identify prostate needle biopsies performed between 2011 and 2014 via the transrectal and the transperineal approach (9,472 and 421 patients, respectively). We characterized trends in utilization and complications using Poisson regression and the Cochrane-Armitage test. We applied logistic regression to examine predictors of complications within 30 days of prostate needle biopsy. RESULTS: Ambulatory use of prostate needle biopsy decreased with time (p <0.01). The most common indication for prostate needle biopsy was elevated prostate specific antigen in 53.2% of patients, followed by active surveillance for cancer in 26.7%, abnormal digital rectal examination in 2.6% and atypia in 1.6%. The prostate needle biopsy associated infection rate increased from 2.6% to 3.5% during the study period (p = 0.02). Among the 777 repeat prostate needle biopsies, the complication rate was comparable to that of initial prostate needle biopsy. Preprocedural rectal swab was done in less than 1% of prostate needle biopsies. On multivariable analysis, patient race, procedure year, diabetes (OR 1.92, 95% CI 1.29-2.86, p <0.01), transrectal approach (OR 3.48, 95% CI 1.27-9.54, p = 0.02) and recent hospitalization (OR 2.03, 95% CI 1.43-2.89, p <0.01) were significantly associated with infection. The median total charge for infectious complications was $4,129 (IQR 711-19,185). CONCLUSIONS: Across New York State, infectious complications after prostate needle biopsy have increased over time. With higher complications using the transrectal approach and minimal utilization of targeted antibiotic prophylaxis, further efforts should focus on the evaluation and implementation of these strategies to reduce post-prostate needle biopsy complications nationally.
