RESUMO

INTRODUCTION: Microsurgical testicular sperm extraction (microTESE) is crucial for treating non-obstructive azoospermia (NOA), offering both 'fresh' and 'frozen' options. This study evaluates the impact of fresh versus frozen microTESE on the progression to intra-cytoplasmic sperm injection (ICSI) cycles, focusing on sperm motility. MATERIALS AND METHODS: We conducted a retrospective analysis of microTESE procedures at a major medical centre from 2007 to 2021, excluding cases of obstructive azoospermia and cryptozoospermia. Patients were divided into two groups: fresh microTESE (Group FR) and frozen microTESE (Group FZ). Sperm motility was assessed, and ICSI outcomes were compared between groups. RESULTS: Out of 128 microTESE procedures on 113 NOA patients, 31 were fresh and 97 were frozen. Sperm was found in 67.7% of fresh cases and 45.3% of frozen cases. In fresh cases, 85.7% had motile sperm for ICSI, whereas in frozen cases, 81.8% had motile sperm initially, but only 52.7% retained motility post-thaw. CONCLUSIONS: Our findings indicate a significant drop in motile sperm availability for ICSI in frozen microTESE cases compared to fresh ones. This suggests a potential advantage of fresh microTESE for certain couples, despite the logistical challenges, highlighting the need for careful patient selection and counselling.

RESUMO

OBJECTIVE: Elevated sperm DNA fragmentation has potential implications for semen quality and fertility. The commonly used sperm chromatin dispersion test offers an indirect estimation but has limitations in terms of bias and variability. This study aimed to assess the reliability of the sperm chromatin dispersion assay for predicting assisted reproductive technology outcomes. MATERIALS AND METHODS: This systematic review included studies published until December 2023 that adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed/MEDLINE, Scopus, and Google Scholar databases were searched. Various assisted reproductive technology outcomes in patients with high (≥ 30%) versus low (< 30%) sperm DNA fragmentation were compared using a sperm chromatin dispersion assay and including a sub-analysis of intracytoplasmic sperm injection versus in vitro fertilization. A comprehensive meta-analysis software facilitated quantitative analysis with statistical comparisons between cases and controls. Interstudy heterogeneity was assessed, and sensitivity and publication bias tests were performed. RESULTS: Of the 199 abstracts assessed, 64 full-text articles were screened, and 44 articles were qualitatively synthesized. Fourteen articles representing 5346 participants were quantitatively analyzed. Using the sperm chromatin dispersion assay, elevated sperm DNA fragmentation was associated with lower fertilization and embryo cleavage rates. Notably, high sperm DNA fragmentation levels did not affect the clinical pregnancy, implantation, miscarriage, or live birth outcomes. Sub-analysis revealed lower fertilization, embryo cleavage, clinical pregnancy, live birth rates, and higher miscarriage rates in the intracytoplasmic sperm injection subgroup only. CONCLUSIONS: The sperm chromatin dispersion assay did not show significant differences in pregnancy or live birth rates between the high- and low-sperm DNA fragmentation groups. Noteworthy, high sperm DNA fragmentation was associated with worse assisted reproductive technology outcomes in the intracytoplasmic sperm injection group. Given the current quality of the evidence, affected by the experimental design and the absence of correction for female factors of infertility, clinicians should be wary of the assay's limited predictive power for pregnancy and live birth outcomes.

RESUMO

IMPORTANCE: Findings from several high profile meta-analyses have raised concerns about an ongoing global decline in sperm concentration and male fertility. However, these studies exhibit considerable heterogeneity in key variables including study population, methodology, fertility status, and geographic region. OBJECTIVE: To perform a systematic review and meta-analysis exploring temporal trends in sperm concentration among fertile men and men unselected for fertility status in the United States. DATA SOURCES: A literature search performed in Scopus and PubMed databases for studies published between 1970 and 2023. Additional studies were included from citations of prior global meta-analyses and reviews evaluating temporal trends in sperm count. STUDY SELECTION AND SYNTHESIS: Studies were included if they presented original data on sperm concentration in US men without known infertility from 1970 to 2023. Aggregate data were assessed across all study populations, with additional subgroup analyses stratified by fertility status and US region. MAIN OUTCOMES: Weighted generalized linear models were generated to evaluate the association between mean sperm concentration and sample collection year. RESULTS: A total of 874 articles were screened, with 58 meeting the inclusion criteria. These represented 75 unique study populations totaling 11,787 men in the United States. Across all study populations, no change in sperm concentration was observed between 1970 and 2018 in unadjusted models (ß = 0.14 million/mL per year). When adjusting for US region, no statistically significant decline in sperm concentration was seen. When adjusting for both region and fertility status, a modest annual decline was observed to meet statistical significance (ß = -0.35 million/mL per year). Of the 49 study populations reporting adequate data to determine mean total sperm count, there was a significant increase in total sperm count of 2.9 million per year between 1970 and 2018. Subgroup analysis found no statistically significant change in mean sperm concentration among any US census region or fertility status cohort. CONCLUSION AND RELEVANCE: In contrast to prior global studies, this analysis suggests no clinically significant decline in sperm concentration among confirmed fertile men and the general male US population without known infertility. Although these findings provide some reassurance against a widespread rapid decline, further studies are necessary to better understand this important topic.

RESUMO

In men with impaired semen parameters, empiric medical therapies such as clomiphene citrate, a selective estrogen receptor modulator (SERM), and anastrozole, a selective aromatase inhibitor, are often employed. The effects of jointly administering these agents on semen parameters are not well understood. Here, we describe the findings of our multi-center, retrospective cohort study of men with idiopathic primary or secondary infertility. Twenty-one men were treated with combination therapy (anastrozole and clomiphene) and 69 men were treated with monotherapy (anastrozole). Patients with pre-treatment normozoospermia and recent or current exogenous testosterone therapy were excluded. Baseline and post-treatment semen and sex hormone parameters were compared among groups. The median follow-up duration was 91 days [interquartile range (IQR), 64-117 days]. Following treatment, 43% of men in the combination therapy group demonstrated normozoospermia, compared to 25% in the monotherapy group. Furthermore, men in the combined group demonstrated marked improvements in total motile sperm count (TMSC) [11.3 vs. 2.1 million (M), P=0.03]. There were no significant differences in hormone levels among the two groups following treatment. Combination therapy with clomiphene citrate and anastrozole was associated with modest benefits in post-treatment semen parameters, when compared to anastrozole monotherapy. These benefits may contribute to improvements in pregnancy outcomes with less invasive assisted reproductive technologies, such as intrauterine insemination (IUI). Future investigations with larger sample sizes and prospective study designs are necessary.

RESUMO

Male-factor infertility is implicated in over half of the millions of cases of infertility worldwide, and varicoceles are the most common correctable cause of male-factor infertility. The pathophysiologic mechanism for varicoceles is complex and next-generation technologies offer promising insights into the molecular underpinnings of this condition. In this narrative review, we highlight historical and contemporary paradigms associated with varicoceles, with an emphasis on the biological underpinnings of this disease. Specifically, we review the literature describing the underlying causes of varicoceles, discuss the molecular and cellular mechanisms causing pathological changes in some (but not all) men, and highlight key articles regarding the next-generation analyses (e.g., transcriptome, epigenome, proteome, and microbiome) being applied to better understand the condition and its treatment. These data demonstrate an ongoing evolution of the knowledge of varicoceles and the potential for improved personalized care in the future for men with this condition.

RESUMO

Male infertility is defined as a failure to conceive after 12 months of unprotected intercourse owing to suspected male reproductive factors. Non-malignant red blood cell disorders are systemic conditions that have been associated with male infertility with varying severity and strength of evidence. Hereditary haemoglobinopathies and bone marrow failure syndromes have been associated with hypothalamic-pituitary-gonadal axis dysfunction, hypogonadism, and abnormal sperm parameters. Bone marrow transplantation is a potential cure for these conditions, but exposes patients to potentially gonadotoxic chemotherapy and/or radiation that could further impair fertility. Iron imbalance might also reduce male fertility. Thus, disorders of hereditary iron overload can cause iron deposition in tissues that might result in hypogonadism and impaired spermatogenesis, whereas severe iron deficiency can propagate anaemias that decrease gonadotropin release and sperm counts. Reproductive urologists should be included in the comprehensive care of patients with red blood cell disorders, especially when gonadotoxic treatments are being considered, to ensure fertility concerns are appropriately evaluated and managed.

RESUMO

Think about 6 loved ones of reproductive age in your life. Now imagine that 1 of these 6 individuals is suffering from infertility. Perhaps they feel alone and isolated, unable to discuss their heartbreak with their closest friends, family, and support network. Suffering in silence. In this editorial, we discuss the infertility journey through the lens of the patients, the providers, and the scientists who struggle with infertility each and every day. Our goal is to open a dialogue surrounding infertility, with an emphasis on dismantling the longstanding societal barriers to acknowledging male infertility as a disease. Through education, communication, compassion, and advocacy, together we can all begin to break the deafening silence of male infertility.

RESUMO

BACKGROUND: Culture-based studies have shown that penile prostheses harbor biofilms in the presence and absence of infection, but these findings have not been adequately validated using contemporary microbiome analytic techniques. AIM: The study sought to characterize microbial biofilms of indwelling penile prosthesis devices according to patient factors, device components, manufacturer, and infection status. METHODS: Upon penile prostheses surgical explantation, device biofilms were extracted, sonicated, and characterized using shotgun metagenomics and culture-based approaches. Device components were also analyzed using scanning electron microscopy. OUTCOMES: Outcomes included the presence or absence of biofilms, alpha and beta diversity, specific microbes identified and the presence of biofilm, and antibiotic resistance genes on each prosthesis component. RESULTS: The average age of participants from whom devices were explanted was 61 ± 11 years, and 9 (45%) of 20 had a diagnosis of diabetes mellitus. Seventeen devices were noninfected, and 3 were associated with clinical infection. Mean device indwelling time prior to explant was 5.1 ± 5.1 years. All analyzed components from 20 devices had detectable microbial biofilms, both in the presence and absence of infection. Scanning electron microscopy corroborated the presence of biofilms across device components. Significant differences between viruses, prokaryotes, and metabolic pathways were identified between individual patients, device manufacturers, and infection status. Mobiluncus curtisii was enriched in manufacturer A device biofilms relative to manufacturer B device biofilms. Bordetella bronchialis, Methylomicrobium alcaliphilum, Pseudoxanthomonas suwonensis, and Porphyrobacter sp. were enriched in manufacturer B devices relative to manufacturer A devices. The most abundant bacterial phyla were the Proteobacteria, Actinobacteria, and Firmicutes. Glycogenesis, the process of glycogen synthesis, was among the predominant metabolic pathways detected across device components. Beta diversity of bacteria, viruses, protozoa, and pathways did not differ among device components. CLINICAL IMPLICATIONS: All components of all penile prostheses removed from infected and noninfected patients have biofilms. The significance of biofilms on noninfected devices remains unknown and merits further investigation. STRENGTHS AND LIMITATIONS: Strengths include the multipronged approach to characterize biofilms and being the first study to include all components of penile prostheses in tandem. Limitations include the relatively few number of infected devices in the series, a relatively small subset of devices included in shotgun metagenomics analysis, and the lack of anaerobic and other expanded conditions for culture. CONCLUSION: Penile prosthesis biofilms are apparent in the presence and absence of infection, and the composition of biofilms was driven primarily by device manufacturer, individual variability, and infection, while being less impacted by device component.

RESUMO

OBJECTIVE: To identify patient factors associated with a clinically significant improvement in semen parameters among infertile men treated with the aromatase inhibitor anastrozole. DESIGN: Multi-institutional retrospective cohort study. SETTING: Two Tertiary Academic Medical Centers. PATIENTS: A total of 90 infertile men treated at 2 tertiary academic medical centers who met inclusion criteria and obtained pretreatment and posttreatment semen analyses. INTERVENTION: Prescription of anastrozole (median 3 mg/wk). MAIN OUTCOME MEASURES: Upgrade in the World Health Organization sperm concentration category (WHO-SCC). Univariate logistic regression, multivariable logistic regression, and partitioning analyses were performed to identify statistically significant patient factors capable of predicting treatment response. RESULTS: With anastrozole treatment, 46% (n = 41/90) of men responded favorably with a WHO-SCC upgrade, and 12% (n = 11/90) experienced a downgrade. Responders exhibited lower pretreatment levels of luteinizing hormone (LH, 4.7 vs. 8.3 IU/L) and follicle-stimulating hormone (4.7 vs. 6.7 IU/mL), higher pretreatment levels of testosterone (T, 356 vs. 265 ng/dL), and similar baseline level of estradiol (E2, 73% vs. 70% with detectible level). Baseline semen parameters differed, with anastrozole responders demonstrating higher baseline semen concentration (3.6 vs. 0.3 M/mL) and higher total motile sperm counts (3.7 vs. 0.1 M). Anastrozole therapy converted 29% (n = 26/90) of the cohort to normozoospermia and enabled intrauterine insemination access in 31% (n = 20/64) of previously ineligible patients. Interestingly, neither body mass index nor the baseline E2 level or E2-T ratio was associated with WHO-SCC upgrade. Multivariable logistic regression revealed the T-LH ratio (odds ratio: 1.02, 95% confidence interval: 1.00-1.03) and baseline nonazoospermia (odds ratio: 9.4, 95% confidence interval: 1.1-78.9) to be statistically significant predictors of WHO-SCC upgrade (area under receiver operating characteristic curve: 0.77). The final user-friendly partitioning model consisting of the T-LH ratio ≥100 and baseline non-azoospermia was 98% sensitive and 33% specific for WHO-SCC upgrades (area under the curve: 0.77). CONCLUSION: Anastrozole therapy decreases serum E2 levels, increases serum gonadotropins, and clinically improves semen parameters in half of men with idiopathic infertility. Nonazoospermic infertile men with T-LH ratios ≥100 are likely to benefit from anastrozole treatment irrespective of baseline E2 level or E2-T ratio. Men with azoospermia rarely respond to anastrozole and should be counseled on alternative treatments.

RESUMO

OBJECTIVE: To assess the incidence of discordant testicular pathology in men undergoing bilateral microdissection testicular sperm extraction (mTESE) and association with sperm retrieval rate. METHODS: We performed a retrospective single-institutional review of all patients undergoing mTESE from 2007 to 2021 and aggregated clinical history, physical exam, semen analysis, and operative findings. Specimens with discordant pathology were re-reviewed by an experienced genitourinary.ßpathologist and categorized in a standardized fashion. Data were analyzed using SPSS. RESULTS: One hundred fourteen non-obstructive azoospermia.ßmen undergoing 132 mTESEs were identified within the study period. Eighty-five percent (112/132) of cases had pathology specimens available, and within this specific cohort the success rate was 41.9% (47/112). A total of 206 pathological reports resulted including 52.4% Sertoli cell only, 4.9% Leydig cell hyperplasia, 8.7% fibrosis, 16.5% maturation arrest, and 17.5% hypospermatogenesis. Twelve percent of testicles had more than 1 pathologic diagnosis. Sixty-six men had synchronous bilateral testicular pathology, and 11/66 (16.6%) had at least partially discordant pathology on initial review. Focused re-review by a genitourinary pathologist confirmed exclusively discordant pathology in 7/66 (10.6%) cases, with a sperm retrieval rate of 57% (4/7). The sperm retrieval rate.ßin men with discordant pathology was not significantly different from those with concordant pathology. CONCLUSION: Over 1 in 10 men undergoing mTESE may have discordant pathology between testicles, though this may not affect sperm retrieval rate.ßat the time of procedure. Clinicians should consider submitting bilateral testicular specimens for pathology to (1) clarify their outcomes data, and (2) assist with clinical decision-making and surgical planning if a repeat mTESE is indicated.

RESUMO

BACKGROUND: Sperm chromatin dispersion test is a common and inexpensive technique to assess sperm DNA fragmentation, but its subjectivity in assessing a small number of spermatozoa is a disadvantage. OBJECTIVES: To study the efficacy of a new sperm chromatin dispersion test kit (R10) combined with an artificial intelligence-aided halo-evaluation platform (X12) and compare the results to those of existing sperm DNA fragmentation testing methods. MATERIALS AND METHODS: Semen samples from normozoospermic donors (n = 10) and infertile men with abnormal semen parameters (n = 10) were enrolled. DNA fragmentation indices were examined by multiple assays, including R10, Halosperm G2 (G2), sperm chromatin structure assay, and terminal deoxynucleotidyl transferase deoxynucleotidyl transferase nick end labeling. In R10 assay, the DNA fragmentation indices were obtained both manually (manual R10) and by X12 (AI-R10). The obtained DNA fragmentation indices were analyzed by agreement analyses. RESULTS: The DNA fragmentation indices obtained by manual R10 and those obtained by AI-R10 showed a strong significant correlation (r = 0.97, p < 0.001) and agreement. The number of spermatozoa evaluated by AI-R10 was 2078 (680-5831). The DNA fragmentation indices obtained by manual R10 and AI-R10 both correlated with those of G2 (r = 0.90, p < 0.001; r = 0.88, p < 0.001). Between the AI-R10 and G2 results, Passing-Bablok regression showed no systematic or proportional difference, and Bland-Altman plots revealed overall agreement and a mean bias of 6.3% with an SD of 6.9% (95% limit of agreement: -7.2% to 19.9%). AI-R10 and sperm chromatin structure assays showed systematic differences with a mean bias of -1.9%, while AI-R10 and terminal deoxynucleotidyl transferase deoxynucleotidyl transferase nick end labeling revealed proportional differences with a mean bias of -10.7%. CONCLUSIONS: The novel sperm chromatin dispersion kit and artificial intelligence-aided platform demonstrated significant correlation and agreement with existing sperm chromatin dispersion methods by assessing greater number of spermatozoa. This technique has the potential to provide a rapid and accurate assessment of sperm DNA fragmentation without technical expertise or flow cytometry.

RESUMO

OBJECTIVE: To better understand the internet advertising material published on clinician websites for the 30,000 men who undergo evaluation for vasectomy reversal (VR), which is a technically demanding procedure requiring microsurgical expertise. METHODS: Internet search trends for "vasectomy" and "vasectomy reversal" from 2004 to 2022 were assessed using Google Trends. Search engines were then queried on a state-by-state basis for physicians performing VR and the available information aggregated and analyzed using standard statistical approaches. RESULTS: VR search volume consistently represented roughly one-tenth of the search volume for vasectomy. One hundred and ninety reversal clinics were identified in 44 of 50 states with the highest number identified in the southeast region and an overall median price of $6500. Ninety percent of physicians were male and completed residencies in urology. Other specialties included obstetrics and gynecology, general surgery, family medicine and orthopedic surgery. Forty-two percent of urologists had completed infertility fellowships. Sixty percent of physicians utilized a microscope, and 4.7% of physicians explicitly stated they did not perform vasoepididymostomy even when indicated. Fifty two percent of clinics reported VR success rates as high as 100%, and 34% of clinics reported pregnancy outcomes. Twenty-five percent of clinics reported out-of-pocket VR pricing and 26% discussed possible complications. CONCLUSION: VR is a technically demanding cash-pay procedure being performed by physicians with a wide array of backgrounds and outcomes. Urologists should strive to lead by example and report their training, personal experiences, and expected outcomes to enable optimal medical decision making for each patient.

RESUMO

In June 2022 the United States Supreme Court issued a ruling in the case Dobbs v. Jackson that overturned Roe v. Wade, the 1973 ruling establishing a federally protected right to abortion in the United States. Anecdotal reports suggested increased vasectomy volume following this event; however, no published data exist. We sought to describe trends in vasectomy consultation before and after the Dobbs v. Jackson ruling (referred to as pre- and post-Dobbs herein). Following IRB approval, we reviewed charts of all adults seeking vasectomy consultation in July-August 2021 and July-August 2022 at a large healthcare organization. We then aggregated vasectomy procedural billing data from 2018 to present. The primary outcome was volume of vasectomy consultation appointments and the secondary outcome was number of vasectomies performed. In July-August 2021 (Pre-Dobbs), 116 men attended vasectomy consultation versus 142 men in July-August 2022 (Post-Dobbs). Median age Post-Dobbs was significantly younger than Pre-Dobbs (35 vs 38 years, respectively, p = 0.01) with a significant increase in Post-Dobbs men under 30 seeking vasectomy (p = 0.005). A total of 16.9% (24/142) of Post-Dobbs men were childless, compared to 8.6% (10/116) of Pre-Dobbs men (p = 0.05). Of those with children, median number of offspring was unchanged at 2. Billing data showed a significant increase in vasectomy procedural volumes Post-Dobbs. While overturning Roe v Wade directly impacted female reproductive rights, number of vasectomy consultations and procedures increased significantly following this decision. Younger men, especially those under 30, as well as childless men were significantly more likely to seek consultation Post-Dobbs compared to the prior reproductive legal climate. While longer-term data are needed, findings indicate that men are invested in maintaining reproductive autonomy for themselves and their partners.

RESUMO

PURPOSE: Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility. MATERIALS AND METHODS: Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field. RESULTS: The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available. CONCLUSIONS: This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.

RESUMO

OBJECTIVE: To determine whether the omission of preprocedure genitourinary exam for vasectomy inherent to a virtual consultation reduces the likelihood of successfully completing in-office vasectomy. Currently, the AUA Vasectomy guidelines encourage in-person examination when possible, though COVID-19 has catalyzed the uptake of virtual consultations at many institutions. We hypothesized that rates of completed in-office vasectomy do not significantly differ between patients examined during consultation in the office and those seen virtually with no exam. METHODS: Virtual vasectomy consults from April to December 2020 were retrospectively reviewed and compared to a size-matched, randomly-selected control group who underwent in-office vasectomy consultation. The primary outcome was completion of in-office bilateral vasectomy. Baseline demographic characteristics were compared. Fisher's exact test and Student's t-test were performed on categorical and continuous variables, respectively. RESULTS: Of 211 patients who underwent virtual vasectomy consultation during the study period, 153 presented for in-office vasectomy. They were compared to 153 vasectomies from the in-person consult cohort. No demographic differences were observed between virtual and in-office consult groups. No statistical difference was observed in completion rates of in-office vasectomy, which was 97.4% (149/153) in the virtual consult cohort and 98.7% (151/153) in the in-office consultation cohort (P = .68). CONCLUSION: Rates of completed in-office vasectomy did not significantly differ based on consult platform, suggesting that a pre-vasectomy physical exam is not required to predict successful completion of the procedure. Telehealth should be utilized as an additional platform to improve access for male contraceptive procedures in a young and busy population.
