RESUMO

PURPOSE: We sought to examine sperm retrieval and testicular histology in males of different ages with Klinefelter syndrome. MATERIALS AND METHODS: We identified all males with Klinefelter syndrome who underwent microdissection testicular sperm extraction at our institution from 1995 to 2020. Patients were divided into adolescent (<20 years) and adult (≥20 years) cohorts. Histology and sperm retrieval were compared using chi-square statistics. Multivariable logistic regression models were used to examine factors associated with successful sperm retrieval. RESULTS: We identified 217 males with Klinefelter syndrome, of whom 59 were adolescents and 158 were adults. Adults were stratified into 10-year groupings (20-29 years, n = 62; 30-39 years, n = 88; ≥40 years, n = 8). Approximately 17% of adolescents had testis histology containing germ cells compared with 15% of the 20 to 29-year cohort, 14% of the 30 to 39-year cohort, and 0% over 40 years. In comparison to adolescents (53%), the sperm retrieval rate was significantly higher in the 20 to 29-year cohort (71%, P = .04) and lower in the ≥40-year cohort (13%, P = .03). In multivariable analysis, the presence of hypospermatogenesis on testis biopsy (OR 5.8, P = .03) was associated with higher odds of successful sperm retrieval. CONCLUSIONS: Younger males more frequently had germ cell-containing testis histology, however this finding was not associated with a higher odds of sperm retrieval. Reproductive urologists should counsel azoospermic males with Klinefelter syndrome that sperm retrieval during adolescence for fertility preservation is not required and can be performed in young adulthood.

RESUMO

In the survivorship setting, adolescent and young adult (AYA) cancer survivors frequently demonstrate little knowledge of infertility risk, are unclear regarding their fertility status, and may under- or overestimate their treatment-related risk for infertility. In female AYA survivors, ovarian function usually parallels fertility, and can be assessed with serum hormone levels and ultrasonography. Posttreatment fertility preservation may be appropriate for survivors at risk for primary ovarian insufficiency. In male AYA survivors, fertility and gonadal function are not always equally affected, and can be assessed with a semen analysis and serum hormones, respectively. As reproductive health issues are commonly cited as an important concern by survivors of AYA cancer, multidisciplinary care teams including oncology, endocrinology, psychology, and reproductive medicine are advocated, with the aim of optimal provision of fertility advice and care for AYA cancer survivors.

RESUMO

BACKGROUND: Despite many available treatments for Peyronie's disease (PD), practice patterns of available therapeutics are not well characterized. OBJECTIVE: We conducted a national survey of urologists to characterize real-world practice patterns of PD management and to characterize the use of therapies discouraged by the American Urological Association guidelines on PD management. MATERIALS AND METHODS: A 34-item survey was distributed via RedCap to urologists who treat patients with PD in all American Urological Association sections. Questions elicited demographic information as well as practices in the diagnosis and treatment of PD. Comparisons were made with Pearson's chi-squared test. The primary outcome was reported use of therapies discouraged by the American Urological Association guidelines on PD. RESULTS: A total of 145 respondents completed the survey, of whom 19% were fellowship trained in andrology/sexual medicine, 36% practiced in an academic setting, and 50% had at least 20 years in practice. Only 60% of respondents reporting performing in-office curvature assessment prior to commencing intralesional injection or surgical treatment, with higher prevalence in andrology/sexual medicine fellowship-trained versus non-fellowship-trained urologists (85% vs. 54%, p = 0.003). The most popular treatment modalities were collagenase clostridium histolyticum (61% of respondents), phosphodiesterase-5 inhibitors (54%), and penile traction (53%). Twenty-one percent of respondents reported currently using a treatment that is explicitly discouraged by the American Urological Association guidelines (extracorporeal shockwave therapy for curvature, L-carnitine, omega-3 fatty acids, or vitamin E). DISCUSSION: Patients seeking PD treatment may be offered different therapies, some of which are not evidence-based, depending on the treating urologist. This study is limited by self-selection and response bias. Its strength is that it represents a cross-sectional overview of real-world practice patterns in PD management, which has not been previously described. CONCLUSIONS: A significant proportion of urologists reported PD management practices that are not evidence-based and not guideline-supported.

RESUMO

OBJECTIVE: To assess changes in antibiotic prophylaxis for inflatable penile prosthesis surgery following publication of the American Urological Association (AUA) Best Practice Statement in April 2008. MATERIALS AND METHODS: The Premier Healthcare Database was queried for inflatable penile prosthesis surgeries from January 2000 to March 2020. The primary outcome was administration of an AUA-adherent antimicrobial regimen and secondary outcome was 90-day explant. Piecewise linear regression was used to compare antimicrobial trends before vs after guideline publication. Multivariable logistic regression models were constructed for primary and secondary outcomes. RESULTS: A total of 26,574 patients who underwent inflatable penile prosthesis surgery were identified, of whom 17,754 (67%) received AUA-adherent antibiotics. After guideline publication, there was a 42% relative increase in AUA-adherent regimen usage, with an increase in the usage trend on piecewise linear regression (from 0.1% to 0.8% of encounters per quarter, R2 = 0.75, P < .001). Increased usage trends were also observed for gentamicin (from 0.0% to 1.0% of encounters per quarter, R2 = 0.84, P < .001) and vancomycin (0.1%-0.7%, R2 = 0.77, P < .001). On multivariable regression, odds of AUA-adherence increased after guideline publication (OR: 1.67, 95% CI: 1.54-1.80, P < .001) and with surgery by a high-volume surgeon (OR: 2.21, 95% CI: 2.07-2.35, P < .01). Nonadherence to an AUA-recommended regimen with use of nonstandard antibiotics (OR: 1.16, 95% CI: 0.78-1.71, P = .5) or excess antibiotics (OR: 0.91, 95% CI: 0.62-1.30, P = .6) was not independently associated with increased risk of 90-day explant. CONCLUSIONS: Publication of the AUA Best Practice Statement was associated with subsequent increases in the usage of guideline-adherent antibiotic regimens, particularly vancomycin and gentamicin, despite absence of level-1 evidence supporting this combination.

RESUMO

RESEARCH QUESTION: What is the impact of advancing paternal age, stratifying for maternal age, on fresh embryo transfer cycle outcomes? DESIGN: All first autologous fresh embryo transfer cycles between 2013 and 2019 at a single high-volume academic institution were retrospectively reviewed. Female age was dichotomized along the cohort median of (37 years) (Female-Young [F-Y]: <37 years; Female-Old [F-O]: ≥37 years). Male age was stratified along the cohort median (38 years) and 90th centile (48 years) (Male-Young [M-Y]: <38 years; Male-Intermediate [M-I]: ≤38 and >48 years; Male-Old [M-O]: ≥48 years). The primary outcome of interest was the odds of live birth using logistic regression. Secondary outcomes included odds of implantation, clinical intrauterine pregnancy and pregnancy loss. All models were adjusted for continuous female age, use of surgically retrieved testicular spermatozoa, severe oligozoospermia and cleavage- versus blastocyst-stage embryo transfer. RESULTS: A total of 6704 couples were included and were divided into six groups based on paternal/maternal age groups (F-Y/M-Y: 2288; F-Y/M-I: 750; F-Y/M-O: 97; F-O/M-Y: 679; F-O/M-I: 2310; F-O/M-O: 580). While some associations were seen on univariable logistic regression, none of the groups with increasing paternal age showed any statistically significant differences on multivariable logistic regression with respect to implantation, clinical intrauterine pregnancy, pregnancy loss or live birth. CONCLUSIONS: Advanced paternal age does not impact clinical outcomes in fresh transfer cycles. The authors postulate that IVF with or without intracytoplasmic sperm injection is able to overcome the deleterious effects of advancing paternal age on sperm quality and subsequent embryo performance.

RESUMO

PURPOSE: To compare the reproductive outcomes of fresh embryo transfer (ET) cycles utilizing fresh versus frozen ejaculated sperm. METHODS: First autologous fresh embryo transfer cycles at a single high-volume academic institution between 2013 and 2019 were retrospectively reviewed. IVF cycles using ejaculated sperm were included, and cycles using donor or surgically retrieved sperm were excluded. Sperm concentration was stratified as ≥ 5 and < 5 million/ml. The primary outcome was live birth, and the secondary outcomes were clinical intrauterine pregnancy (IUP) and miscarriage. A multivariable logistic regression model for the aforementioned outcomes was adjusted a priori for sperm concentration as well as maternal and paternal age. RESULTS: A total of 6128 couples were included. Of these, 5780 (94.3%) utilized fresh sperm, and 348 (5.7%) frozen sperm. A total of 5716 (93.2%) had sperm concentrations ≥ 5 million/ml and 412 (6.7%) had sperm concentrations < 5 million/ml. On multivariable logistic regression, the use of freshly ejaculated sperm was not associated with significantly different odds of clinical IUP, miscarriage, or live birth when compared to cycles using frozen sperm. CONCLUSION: For couples conceiving via fresh ET, the use of fresh versus frozen ejaculated sperm is not associated with reproductive outcomes.

RESUMO

INTRODUCTION: Klinefelter Syndrome (KS) is the most common genetic condition cause of non-obstructive azoospermia (NOA). KS also often results in decreased testicular growth and testosterone production. Because of this, exogenous testosterone therapy is commonly prescribed for KS patients to treat hypogonadism, but this may have additional impacts to future fertility potential. KS adolescent patients may be asked to provide multiple semen samples to identify potential sperm for early cryopreservation. OBJECTIVE: To develop a multi-institutional database to evaluate the prevalence of sperm in the ejaculate of adolescent KS patients. METHODS: A retrospective study was performed of all adolescent KS patients seen at two high-volume tertiary male infertility clinics between 2015 and 2020. Adolescence was defined as individuals aged 12-19 years, as per the World Health Organization. Demographic information data including weight, height, medical comorbidities, and concurrent medications were collected. Serum hormone levels including FSH, LH, and testosterone were collected, as well as any available semen analysis data. RESULTS: A total of 116 patients were identified and included in the database. A total of 100 (86.2%) had hormone data available and 48 (41.3%) had semen analysis data. Of the 48 patients with semen analyses, only 4 (8.3%) patients had rare sperm in the ejaculate while the remaining had azoospermia (91.7%). None of the specimens were suitable for cryopreservation. The average serum total testosterone level of adolescent KS patients was 181 ± 216 ng/dL. FSH levels were 14.3 ± 18.8 IU/L (normal 0.3-10.0 IU/L) and LH levels were 7.8 ± 12.4 IU/L (normal 1.2-7.8 IU/L). A total of 17 patients repeated a semen analysis, and in no instance did this result in sperm where there was none previously. CONCLUSION: The findings from a large multicenter retrospective cohort of adolescent KS patients suggest that a single semen analysis is sufficient for attempted cryopreservation purposes, and that multiple semen analyses is not needed.

RESUMO

PURPOSE: To assess the impact of microsurgical varicocelectomy technique on clinical outcomes. METHODS: Men diagnosed with varicocele between 2017 and 2020 were reviewed. We included men who underwent microsurgical varicocelectomy by two high-volume surgeons who differed in surgical technique: Method (1) testicular delivery with gubernacular vein ligation, and ligation of vasal veins > 2.5 mm; Method (2) no delivery and ligation of dilated vasal veins in cases of recurrence. Post-operative changes for semen parameters, DNA fragmentation, and serum testosterone were evaluated for each technique and compared. RESULTS: 313 patients were included; 162 with Method 1 and 151 with Method 2. The cohorts were of similar age (median 35 years, interquartile range (IQR) 28-43; 34, IQR 28-39, respectively), and BMI (25 kg/m2, IQR 23-27; 25, IQR 23-28, respectively). For Method 1, 84 (51.9%) had bilateral surgery, and 78 (48.1%) had unilateral surgery. For Method 2, 63 (41.7%) had bilateral surgery, and 88 (58.3%) unilateral surgery. In patients with sperm concentration > 5 M/mL, both techniques resulted in an improvement (p < 0.01), but there was no difference between the methods (p = 0.18). Both methods were associated with an improvement in total motile count (p < 0.05) and the amount of DNA fragmentation (p < 0.05), although no differences were apparent between the techniques (p = 0.09, p = 0.81, respectively). Finally, testosterone levels improved with Method 1, but the post-operative difference was not different than Method 2 (p = 0.06). CONCLUSION: Delivery of the testis and ligation of dilated vasal veins compared to not performing those steps do not impact semen parameters, but are associated with improvement in testosterone levels.

RESUMO

INTRODUCTION: Immunocompromised patients are postulated to have higher rates of post-operative infection. We sought to determine if inflatable penile prosthesis (IPP) reoperation rates (due to infection, erosion, device malfunction or patient dissatisfaction) are higher among immunocompromised men. METHODS: We analyzed men who underwent initial IPP insertion from 2000 to 2016 in the New York Statewide Planning and Research Cooperative System database. Immunocompromised patients were propensity-score matched in a 1:3 fashion with immunocompetent patients. We estimated and compared reoperation rates (including removal, reoperation due to infection, revision, or replacement of an IPP after an index procedure) at 30 days, 90 days, 1 year and 3 years of follow up between immunocompromised men and controls by performing a Kaplan Meier analysis and Log-rank tests. Cox proportional hazards models were built to examine the overall association between immune deficient status and the risk of reoperation. MAIN OUTCOME MEASURE: Reoperation rate and time to reoperation after index IPP placement. RESULTS: A total of 245 immunocompromised patients who received an initial IPP between 2000 and 2016 were identified. After propensity score matching, we analyzed 235 immunocompromised men and 705 controls. There was no difference in overall reoperation rates between immunocompromised men and controls within any time period assessed (30 days, 90 days, 1 year, or 3 years). In our Cox proportional hazards model, the hazards of overall reoperation, removal, or revision/replacement (HR 1.11 [95% CI 0.74-1.67], HR 1.58 [95% CI 0.90-2.79)], and HR 0.83 [95% CI 0.47-1.45], respectively) were not significant different between immunocompromised men and controls. Reoperation due to infection was also not significantly different between immunocompromised and immunocompetent men (HR 2.06 [95% CI 0.97-4.40]). STRENGTHS & LIMITATIONS: This study is strengthened by its size as the largest cohort of immunocompromised men treated with IPP to date in the literature, but is limited by the retrospective nature of the database which may introduce selection bias and by the low event rate for IPP reoperation. CONCLUSIONS: Reoperation rates, including those due to infection, are not significantly different between immunocompromised men and immunocompetent controls. Therefore, immune status in appropriately selected candidates does not appear to place patients at substantially higher risk of explant or revision. Gaffney CD, Fainberg J, Aboukhshaba A, et al.

RESUMO

Varicocele refers to an abnormally dilated and tortuous pampiniform venous plexus within the spermatic cord. The prevalence of varicocele is reported to be approximately 15% in the general male population. Its incidence increases with age and has a higher incidence in infertile men. Varicocele treatment (surgical or interventional) is considered one of the most common therapies of reversible infertility in men. Percutaneous embolization offers nonsurgical, minimally invasive option for the treatment of varicoceles, requiring only minimal sedation. In this article, the authors review the clinical and technical details of percutaneous varicocele embolization with a summary of currently available evidence.

RESUMO

Our study aimed to assess for predictors of varicocele-associated pain and whether it predicts semen parameters after microsurgical varicocelectomy. We assessed all men diagnosed with a varicocele by two surgeons from 2017 to 2020, excluding those who did not undergo surgical treatment. Patients were stratified based on the presence of pain at clinical assessment, and these groups were compared. Logistic regression models were utilised to assess for predictors of pain. A total of 313 men were included, with relatively similar proportions completed by both surgeons (48.2% and 51.8%). A total of 98 (31.3%) had typical varicocele-associated pain at the time of assessment. The pain group was younger than the no pain group (30.5 versus. 35.0, respectively, p < .01), and those with pain had greater varicocele grades (p = .008). Although not statistically different, there was a greater portion of left-sided only varicoceles in the pain group (p = .09). No significant differences were demonstrated between sperm concentration, motility, volume or morphology pre-operatively, or post-operatively between groups. Younger age and varicocele grade were predictive of varicocele-associated pain. In conclusion, almost 1/3 of men presented with varicocele-associated pain. Pain does not predict response to varicocelectomy, but these men tend to be younger, and have higher grade varicoceles.

RESUMO

OBJECTIVES: To evaluate the extent to which erectile dysfunction (ED) is managed by urologists versus non-urologists. We sought to characterize the epidemiology, diagnosis, and outpatient treatment of ED using a nationally representative cohort. METHODS: We examined all male patient visits between 2006 and 2016 in the National Ambulatory Medical Care Survey, a survey designed to provide a nationally representative estimate of ambulatory visits in the United States. Distribution of ED diagnoses among physician specialties was determined. Demographic, clinical, and treatment characteristics of men with ED seeing urologists versus non-urologists were compared using chi-squared tests. RESULTS: Among the 170,499 patient visits analyzed, 1.2% were associated with a diagnosis of ED, which translated into 3,409,244 weighted visits annually. Visits for ED were predominantly seen by urologists (58.0%) and family practitioners (26.2%). Men visiting non-urologists for ED were more likely to be younger than 65 (77.4% vs 52.9%, P < .05). Men seeing urologists for ED more frequently had an active cancer diagnosis (24.2% vs 2.8%, P < .05). Non-urologists more readily ordered or reordered phosphodiesterase-5 inhibitors for men with ED (66.62% vs 50.77%, P < .05). Advanced therapies such as intracavernosal injections and intra-urethral agents were almost exclusively ordered by urologists compared to non-urologists (2.72% vs 0.25%, P < .05). CONCLUSION: Almost half of all ED visits were seen by non-urologist providers, who were much less likely than urologists to order advanced pharmacologic therapies. This difference in prescribing patterns presents an opportunity for interdisciplinary collaboration and education to ensure that all patients seeking treatment for ED are receiving guideline-based care.

RESUMO

OBJECTIVE: To assess the impact of ejaculatory hood (EH)-sparing transurethral vaporization of the prostate (TUVP) on sexual function, with a specific focus on erectile and ejaculatory function. METHODS: We studied 25 patients who underwent EH-sparing Photo Selective Vaporization of the Prostate using the Greenlight Laser or Bipolar Button Plasma Vaporization of the Prostate from August 2016 to March 2018. All patients were sexually active with anterograde ejaculation prior to treatment. Patients completed the Male Sexual Health Questionnaire (MSHQ) and AUA Symptom Score pre- and postoperatively. We compared preprocedure sexual function with postprocedure sexual function at 1- and 3-month intervals. A logistic regression model was used to identify predictors of improvement in sexual function. RESULTS: Twenty-five patients underwent EH-sparing TUVP from August 2016 to March 2018. At 3-months postoperatively, patients had significant improvement in erection score (12 vs 9, P = .04) and erection bother score (5 vs 3.5, P <.01) compared to baseline. They also had improvement in ejaculation score (26 vs 23, P = .03), ejaculation bother score (5 vs 4, P = .01), and total MSHQ score (87.5 vs 73, P = .01). Anterograde ejaculation was preserved in 80.0% of patients. Logistic regression identified higher AUA score severity as an independent predictor of MSHQ score improvement (1.32, CI: 1.03-1.69, P = .03). CONCLUSION: At 3 months postoperatively, the majority of men who underwent EH-sparing TUVP had preserved anterograde ejaculation and improved overall sexual function based on MSHQ survey. This validates EH-sparing TUVP in men with BPH who wish to maintain sexual function.

RESUMO

Prostate cancer is the most common malignancy in men and the second leading cause of cancer-related death in men. Radiotherapy is a curative option that is administered via external beam radiation, brachytherapy, or in combination. Sexual dysfunction is a common toxicity following radiotherapy, similar to men undergoing radical prostatectomy, but the etiology is different. The pathophysiology of radiation-induced sexual dysfunction is multi-factorial, and the toxicity is a major cause of impaired quality of life among long-term prostate cancer survivors. Management of a patient's sexual function during and after radiotherapy requires multidisciplinary coordination of care between radiation oncology, urology, psychiatry, pharmacy, and dermatology. This review provides a framework for clinicians to better understand prostatic radiotherapy-induced sexual dysfunction diagnosis, evaluation, and a patient-centered approach to toxicity preventive strategies and management.

RESUMO

RESEARCH QUESTIONS: Can a previously defined relationship between sperm capacitation and the probability of a man generating pregnancy within three cycles, prospectively predict male fertility in diverse clinical settings? A second study asked, what is the prevalence of impaired sperm fertilizing ability in men questioning their fertility (MQF), and does this relate to traditional semen analysis metrics? DESIGN: In the multicentric, prospective observational study, data (n = 128; six clinics) were analysed to test a published relationship between the percentage of fertilization-competent, capacitated spermatozoa (Cap-Score) and probability of generating pregnancy (PGP) within three cycles of intrauterine insemination. Logistic regression of total pregnancy outcomes (n = 252) assessed fit. In the cohort comparison, Cap-Scores of MQF (n = 2155; 22 clinics) were compared with those of 76 fertile men. RESULTS: New outcomes (n = 128) were rank-ordered by Cap-Score and divided into quintiles (25-26 per group); chi-squared testing revealed no difference between predicted and observed pregnancies (P = 0.809). Total outcomes (n = 252; 128 new + 124 previous) were pooled and the model recalculated, yielding an improved fit (P < 0.001). Applying the Akaike information criterion found that the optimal model used Cap-Score alone. Cap-Scores were performed on 2155 men (with semen analysis data available for 1948). To compare fertilizing ability, men were binned by PGP (≤19%, 20-29%, 30-39%, 40-49%, 50-59%, ≥60%). Distributions of PGP and the corresponding Cap-Scores were significantly lower in MQF versus fertile men (P < 0.001). Notably, 64% of MQF with normal volume, concentration and motility (757/1183) had PGP of 39% or less (Cap-Scores ≤31), versus 25% of fertile men. CONCLUSIONS: Sperm capacitation prospectively predicted male fertility. Impaired capacitation affects many MQF with normal semen analysis results, informing diagnosis versus idiopathic infertility.

RESUMO

Prostate cancer is the most common malignancy and the second leading cause of cancer-related death in men. Radiotherapy is a curative option that is administered via external beam radiation, brachytherapy, or in combination. Erectile, ejaculatory and orgasm dysfunction(s) is/are known potential and common toxicities associated with prostate radiotherapy. Our multidisciplinary team of physicians and/or scientists have written a three (3) part comprehensive review of the pathogenesis and management radiation-induced sexual dysfunction. Part I reviews pertinent anatomy associated with normal sexual function and then considers the pathogenesis of prostate radiation-induced sexual toxicities. Next, our team considers the associated radiobiological (including the effects of time, dose and fractionation) and physical (treatment planning and defining a novel Organ at Risk (OAR)) components that should be minded in the context of safe radiation treatment planning. The authors identify an OAR (i.e., the prostatic plexus) and provide suggestions on how to minimize injury to said OAR during the radiation treatment planning process.

RESUMO

Introduction and Objectives: After transurethral prostatectomy, erectile dysfunction and ejaculatory dysfunction are significant concerns for patients. We compared ejaculatory hood-sparing technique in patients who underwent photoselective vaporization of the prostate using the GreenLight Laser (EjS-PVP) with the ejaculatory hood-sparing technique in patients who underwent bipolar button plasma vaporization of the prostate (EjS-BPVP) in the surgical management of benign prostatic hyperplasia (BPH). Materials and Methods: Twenty-seven patients were randomized to either undergo EjS-PVP or EjS-BPVP from August 2016 to March 2018. All of the patients were sexually active with antegrade ejaculation before prostatectomy. We evaluated International Prostate Symptom Score (IPSS), quality of life (QoL), peak flow rate (Qmax), postvoid residual volume (PVR), International Index of Erectile Function and ejaculatory function by the Male Sexual Health Questionnaire (MSHQ). Men were evaluated preoperatively and at 1, 3, and 6 months postoperatively. The primary outcome was ejaculation preservation measured as no change or preservation in antegrade ejaculate at the last follow-up visit by MSHQ (6 months). Results: Twenty-seven patients with a mean age of 65.6 ± 8.4 years underwent either EjS-BPVP or EjS-PVP (Table 1). There were no differences in baseline characteristics between the two groups. Improvements in IPSS, QoL, Qmax, and PVR were durable throughout the study period in both groups. There was no difference in outcomes between groups. Postoperatively, there was no change in ejaculatory function with EjS-BPVP utilizing either 180 W EjS-PVP or bipolar energy. The change in MSHQ Ejaculation Scale was -2.1 and -5.4 at 6 months in both arms. The 6-month ejaculatory preservation rate was 85% in the EjS-PVP group and 78% in the EjS-BPVP group. Conclusions: EjS GreenLight photoselective vaporization and bipolar plasma button vaporization is a safe and effective method for treating men with lower urinary tract symptoms secondary to BPH with maintenance of antegrade ejaculation.
