RESUMO

INTRODUCTION: On June 24, 2022, the US Supreme Court issued its decision on Dobbs v Jackson Women's Health Organization (Dobbs). This decision had major implications on female reproductive choices, but also had potential implications on their male counterparts. We sought to determine the association of Dobbs with the number and characteristics of men seeking vasectomy. METHODS: A retrospective review was performed to determine the number of vasectomy consults and procedures completed at a single Michigan health system in the 6 months following Dobbs (June 24, 2022-December 24, 2022) vs the same 6-month time frame between 2019 and 2021. Another retrospective review was conducted in the 3 months following Dobbs (June 24, 2022-September 24, 2022) vs the same days in 2021 to determine the number of vasectomy consults completed and to evaluate for differences in the characteristics of these men. RESULTS: In the 6 months after Dobbs, there was a 150% and 160% increase in vasectomy consults and procedures completed, respectively, compared to a similar time frame in 2019 to 2021. In the 3 months after Dobbs, there was a 225% increase in new vasectomy consults compared to a similar time frame in 2021. There were no differences in the age, race, religion, median household income, or insurance type of men seeking vasectomy consult pre- vs post-Dobbs. Partnerless men (odds ratio 3.66) and those without children (odds ratio 2.85) were more likely than married men and those with 3 or more children, respectively, to seek vasectomy consult post-Dobbs. CONCLUSIONS: Dobbs was associated with a marked increase in vasectomy consultations and procedures at our institution in the state of Michigan. Future studies are needed to determine the long-term implications of Dobbs on vasectomy practices and determine if vasectomy practices differ by states and their respective abortion laws.

RESUMO

OBJECTIVE: To examine the relationship between antisperm antibody (ASA), pregnancy rates, and method of conception following vasectomy reversal, given that before and after vasectomy reversal, patients wonder if ASAs will prevent them from achieving pregnancy and American Urological Association vasectomy guidelines call for additional research to answer this question. METHODS: We performed retrospective chart review and phone interview of patients who underwent vasectomy reversal at our institution from 1/1/2000 to 12/31/2018. We excluded patients who underwent vasectomy reversal for pain, or without postoperative semen analysis with ASA. We categorized patients as having low (<50%) or high (≥50%) ASA levels using the first postoperative semen analysis. Our primary outcome was pregnancy rate, including method of conception. Differences in pregnancy rates were tested using Fisher exact test. RESULTS: Two hundred and four patients were chart reviewed. Median age at time of surgery was 40years and median obstruction interval was 7.3years. Median partner age was 32years. One hundred sixty-four (80%) patients underwent bilateral vasovasostomy. Eighty-five patients (42%) had low (<50%) ASA levels and 119 (58%) had high (≥50%) ASA levels. Sixty-seven patients completed phone interviews. Of 27 men with low ASA levels, 19 (70%) achieved a pregnancy with 16 (59%) spontaneous pregnancy. Of 40 men with high ASA levels, 30 (75%) achieved a pregnancy with 16 (40%) spontaneous pregnancy. The Fisher exact test P-value was .2. CONCLUSION: ASA levels are not associated with pregnancy rate or method of conception after vasectomy reversal. These findings can improve patient counseling before and after vasectomy reversal.

RESUMO

BACKGROUND: Health care claims have an inherent limitation in that noncovered services are unreported. This limitation is particularly problematic when researchers wish to study the effects of changes in the insurance coverage of a service. In prior work, we studied the change in the use of in vitro fertilization (IVF) after an employer added coverage. To estimate IVF use before coverage began, we developed and tested an Adjunct Services Approach that identified patterns of covered services cooccurring with IVF. METHODS: Based on clinical expertise and guidelines, we developed a list of candidate adjunct services and used claims data after IVF coverage began to assess associations of those codes with known IVF cycles and whether any additional codes were also strongly associated with IVF. The algorithm was validated by primary chart review and was then used to infer IVF in the precoverage period. RESULTS: The selected algorithm included pelvic ultrasounds and either menotropin or ganirelix, yielding a sensitivity of 93.0% and specificity of >99.9%. DISCUSSION: The Adjunct Services Approach effectively assessed the change in IVF use postinsurance coverage. Our approach can be adapted to study IVF in other settings or to study other medical services experiencing coverage changes (eg, fertility preservation, bariatric surgery, and sex confirmation surgery). Overall, we find that an Adjunct Services Approach can be useful when (1) clinical pathways exist to define services delivered adjunct to the noncovered service, (2) those pathways are followed for most patients receiving the service, and (3) similar patterns of adjunct services occur infrequently with other procedures.

RESUMO

OBJECTIVE: To examine the percentage of patients who filled peri-procedural opioid prescriptions before and after Blue Cross Blue Shield of Michigan (BCBSM) launched a modifier 22 payment incentive for opioid-sparing vasectomies in Michigan on July 1, 2019. METHODS: We evaluated BCBSM administrative claims data from February 1, 2018 - November 16, 2020 for men 20 - 64 years old who underwent vasectomy or a control office-based urologic procedure (cystourethroscopy, prostate biopsy, circumcision, and transurethral destruction of prostate tissue.) The primary outcome was the percentage of patients who filled opioid prescriptions 30 days before to 3 days after their procedure. We performed an interrupted time series analysis to estimate changes in the percentage of patients who filled opioid prescriptions in the vasectomy and control group before and after July 1, 1019. RESULTS: Our cohort included 4,559 men who had a vasectomy and 4,679 men who had a control procedure. Within each group, demographics and clinical factors were similar before and after July 1, 2019. Before implementation of the modifier 22 policy, 32.5% of men who had a vasectomy filled an opioid prescription whereas only 12.6% of men filled an opioid prescription after July 1, 2019 -a 19.9% absolute reduction and 61.0% relative reduction (P < .001). In the control group, there was no significant change in the percentage of patients who filled opioid prescriptions before and after July 1, 2019 (0.8% absolute increase, P = .671). CONCLUSION: Implementation of modifier 22 based financial incentive for opioid-sparing vasectomies was associated with decrease in the percentage of men who filled opioid prescriptions after vasectomy.

RESUMO

PURPOSE: There is an age-related decline in male testosterone production. It is therefore surprising that young men are evaluated for testosterone deficiency with the same cutoff of 300 ng/dL that was developed from samples of older men. Our aim is to describe normative total testosterone levels and age-specific cutoffs for low testosterone levels in men 20 to 44 years old. MATERIALS AND METHODS: We analyzed the 2011-2016 National Health and Nutrition Examination Surveys, which survey nationally representative samples of United States residents. Men 20 to 44 years old with testosterone levels were included. Men on hormonal medications, with a history of testicular cancer or orchiectomy, and with afternoon/evening laboratory values were excluded. We separated men into 5-year intervals and evaluated the testosterone levels of each age group, and for all men 20 to 44 years old. We used the American Urological Association definition of a "normal testosterone level" (the "middle tertile") to calculate age-specific cutoffs for low testosterone levels. RESULTS: Our final analytic cohort contained 1,486 men. Age-specific middle tertile levels were 409-558 ng/dL (20-24 years old), 413-575 ng/dL (25-29 years old), 359-498 ng/dL (30-34 years old), 352-478 ng/dL (35-39 years old), and 350-473 ng/dL (40-44 years old). Age-specific cutoffs for low testosterone levels were 409, 413, 359, 352, and 350 ng/dL, respectively. CONCLUSIONS: Diagnosis of testosterone deficiency has traditionally been performed in an age-indiscriminate manner. However, young men have different testosterone reference ranges than older men. Accordingly, age-specific normative values and cutoffs should be integrated into the evaluation of young men presenting with testosterone deficiency.

RESUMO

Objective: To describe the prevalence and treatment characteristics of assisted reproductive technology (ART) cycles involving specific male factor infertility diagnoses in the United States. Design: Cross-sectional analysis of ART cycles in the National ART Surveillance System (NASS). Setting: Clinics that reported patient ART cycles performed in 2017 and 2018. Patients: Patients who visited an ART clinic and the cycles were reported in the NASS. The ART cycles included all autologous and donor cycles that used fresh or frozen embryos. Interventions: Not applicable. Main Outcome Measures: Analyses used new, detailed reporting of male factor infertility subcategories, treatment characteristics, and male partner demographics available in the NASS. Results: Among 399,573 cycles started with intent to transfer an embryo, 30.4% (n = 121,287) included a male factor infertility diagnosis as a reason for using ART. Of these, male factor only was reported in 16.5% of cycles, and both male and female factors were reported in 13.9% of cycles; 21.8% of male factor cycles had >1 male factor. Abnormal sperm parameters were the most commonly reported diagnoses (79.7%), followed by medical condition (5.3%) and genetic or chromosomal abnormalities (1.0%).Males aged ≤40 years comprised 59.6% of cycles with male factor infertility. Intracytoplasmic sperm injection was the primary method of fertilization (81.7%). Preimplantation genetic testing was used in 26.8%, and single embryo transfer was used in 66.8% of cycles with male factor infertility diagnosis. Conclusions: Male factor infertility is a substantial contributor to infertility treatments in the United States. Continued assessment of the prevalence and characteristics of ART cycles with male factor infertility may inform treatment options and improve ART outcomes. Future studies are necessary to further evaluate male factor infertility.

RESUMO

Unexplained infertility affects about one-third of infertile couples and is defined as the failure to identify the cause of infertility despite extensive evaluation of the male and female partners. Therefore, there is a need for a multiparametric approach to study sperm function. Recently, we developed a Fluorescence-Based Ratiometric Analysis of Sperm Centrioles (FRAC) assay to determine sperm centriole quality. Here, we perform a pilot study of sperm from 10 fertile men and 10 men in couples with unexplained infertility, using three centriolar biomarkers measured at three sperm locations from two sperm fractions, representing high and low sperm quality. We found that FRAC can identify men from couples with unexplained infertility as the likely source of infertility. Higher quality fractions from 10 fertile individuals were the reference population. All 180 studied FRAC values in the 10 fertile individuals fell within the reference population range. Eleven of the 180 studied FRAC values in the 10 infertile patients were outliers beyond the 95% confidence intervals (P = 0.0008). Three men with unexplained infertility had outlier FRAC values in their higher quality sperm fraction, while four had outlier FRAC values in their lower quality sperm fraction (3/10 and 4/10, P = 0.060 and P = 0.025, respectively), suggesting that these four individuals are infertile due, in part, to centriolar defects. We propose that a larger scale study should be performed to determine the ability of FRAC to identify male factor infertility and its potential contribution to sperm multiparametric analysis.

RESUMO

OBJECTIVE: We sought to characterize demographics, costs, and workplace support for surgeons using assisted reproductive technology (ART), adoption, and surrogacy to build their families. SUMMARY BACKGROUND DATA: As the surgical workforce diversifies, the needs of surgeons building a family are changing. ART, adoption, and surrogacy may be used with greater frequency among female surgeons who delay childbearing and surgeons in same-sex relationships. Little is known about costs and workplace support for these endeavors. METHODS: An electronic survey was distributed to surgeons through surgical societies and social media. Rates of ART use were compared between partners of male surgeons and female surgeons and multivariate analysis used to assess risk factors. Surgeons using ART, adoption, or surrogacy were asked to describe costs and time off work to pursue these options. RESULTS: Eight hundred and fifty-nine surgeons participated. Compared to male surgeons, female surgeons were more likely to report delaying children due to surgical training (64.9% vs. 43.5%, P < 0.001), have fewer children (1.9 vs. 2.4, p < 0.001), and use ART (25.2% vs. 17.4%, P = 0.035). Compared to non-surgeon partners of male surgeons, female surgeons were older at first pregnancy (33 vs 31 years, P < 0.001) with age > 35 years associated with greater odds of ART use (odds ratio 3.90; 95% confidence interval 2.74-5.55, P < 0.001). One-third of surgeons using ART spent >$40,000; most took minimal time off work for treatments. Forty-five percent of same-sex couples used adoption or surrogacy. 60% of surgeons using adoption or surrogacy spent >$40,000 and most took minimal paid parental leave. CONCLUSIONS: ART, adoption, or surrogacy is costly and lacks strong workplace support in surgery, disproportionately impacting women and same-sex couples. Equitable and inclusive environments supporting all routes to parenthood ensure recruitment and retention of a diverse workforce. Surgical leaders must enact policies and practices to normalize childbearing as part of an early surgical career, including financial support and equitable parental leave for a growing group of surgeons pursuing ART, surrogacy, or adoption to become parents.

RESUMO

OBJECTIVE: To compare racial differences in male fertility history and treatment. DESIGN: Retrospective review of prospectively collected data. SETTING: North American reproductive urology centers. PATIENT(S): Males undergoing urologist fertility evaluation. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Demographic and reproductive Andrology Research Consortium data. RESULT(S): The racial breakdown of 6,462 men was: 51% White, 20% Asian/Indo-Canadian/Indo-American, 6% Black, 1% Indian/Native, <1% Native Hawaiian/Other Pacific Islander, and 21% "Other". White males sought evaluation sooner (3.5 ± 4.7 vs. 3.8 ± 4.2 years), had older partners (33.3 ± 4.9 vs. 32.9 ± 5.2 years), and more had undergone vasectomy (8.4% vs. 2.9%) vs. all other races. Black males were older (38.0 ± 8.1 vs. 36.5 ± 7.4 years), sought fertility evaluation later (4.8 ± 5.1 vs. 3.6 ± 4.4 years), fewer had undergone vasectomy (3.3% vs. 5.9%), and fewer had partners who underwent intrauterine insemination (8.2% vs. 12.6%) compared with all other races. Asian/Indo-Canadian/Indo-American patients were younger (36.1 ± 7.2 vs. 36.7 ± 7.6 years), fewer had undergone vasectomy (1.2% vs. 6.9%), and more had partners who underwent intrauterine insemination (14.2% vs. 11.9%). Indian/Native males sought evaluation later (5.1 ± 6.8 vs. 3.6 ± 4.4 years) and more had undergone vasectomy (13.4% vs. 5.7%). CONCLUSION(S): Racial differences exist for males undergoing fertility evaluation by a reproductive urologist. Better understanding of these differences in history in conjunction with societal and biologic factors can guide personalized care, as well as help to better understand and address disparities in access to fertility evaluation and treatment.

RESUMO

OBJECTIVE: To study the use of video visits for male infertility care prior to the COVID-19 pandemic METHODS: We reviewed video visits for male infertility patients completed at a tertiary academic center in southeast Michigan. These patients had follow-up after an initial in-person evaluation. We designed this retrospective case series to describe the diagnostic categories seen through telehealth, management steps completed during video visits, and to understand whether additional in-person care was required within 90 days of video visits. In addition, we estimated time and cost savings for patients attributed to video visits. RESULTS: Most men seen during video visits had an endocrinologic (29%) or anatomic (21%) cause for their infertility. 73% of video visits involved reviewing results; 30% included counseling regarding assistive reproductive technologies; and 25% of video visits resulted in prescribing hormonally active medications. The two patients (3%) who were seen in clinic after their video visit underwent a varicocelectomy in the interim. No patients required an unplanned in-person visit. From a patient perspective, video visits were estimated to save a median of 97 minutes (IQR 64-250) of travel per visit. Median cost savings per patient- by avoiding travel and taking time off work for a clinic visit-were estimated to range from $149 (half day off) to $252 (full day off). CONCLUSION: Video visits for established male infertility patients were used to manage different causes of infertility while saving patients time and money. Telehealth for established patients did not trigger additional in-person evaluations.

RESUMO

Although a wide array of interventions exist for men seeking fertility after vasectomy, up to 6% of them will elect for a vasectomy reversal. While the widespread adoption of telemedicine promises convenience and improved access, lack of ability to do a physical examination may hinder appropriate counselling. Although vasectomy reversal is successfully completed in most of the men either with a vasovasostomy or a vasoepididymostomy, there could be various reasons for the inability to successfully complete the operation. Our commentary outlines the reasons why a vasectomy reversal is not possible or successful. We also discuss a pre-operative management algorithm in men seeking vasectomy reversal to ensure appropriate counselling with a thorough pre-operative history, physical examination and on occasion, hormonal evaluation.

RESUMO

Semen analysis is the cornerstone of evaluating male infertility, but it is imperfect and insufficient to diagnose male infertility. As a result, about 20% of infertile males have undetermined infertility, a term encompassing male infertility with an unknown underlying cause. Undetermined male infertility includes two categories: (i) idiopathic male infertility-infertile males with abnormal semen analyses with an unknown cause for that abnormality and (ii) unexplained male infertility-males with "normal" semen analyses who are unable to impregnate due to unknown causes. The treatment of males with undetermined infertility is limited due to a lack of understanding the frequency of general sperm defects (e.g., number, motility, shape, viability). Furthermore, there is a lack of trusted, quantitative, and predictive diagnostic tests that look inside the sperm to quantify defects such as DNA damage, RNA abnormalities, centriole dysfunction, or reactive oxygen species to discover the underlying cause. To better treat undetermined male infertility, further research is needed on the frequency of sperm defects and reliable diagnostic tools that assess intracellular sperm components must be developed. The purpose of this review is to uniquely create a paradigm of thought regarding categories of male infertility based on intracellular and extracellular features of semen and sperm, explore the prevalence of the various categories of male factor infertility, call attention to the lack of standardization and universal application of advanced sperm testing techniques beyond semen analysis, and clarify the limitations of standard semen analysis. We also call attention to the variability in definitions and consider the benefits towards undetermined male infertility if these gaps in research are filled.

RESUMO

Male infertility is a common disease. Male infertility is also a core competency of urology training and clinical practice. In this white paper from the Society for the Study of Male Reproduction and the Society for Male Reproduction and Urology, we identify and define different physician productivity plans. We then describe the advantages and disadvantages of various physician productivity measurement systems for male infertility practices. We close with recommendations for measuring productivity that we hope urologists and administrators can use when creating productivity plans for male infertility practices.

RESUMO

Although infertility is now recognized as a disease by multiple organizations including the World Health Organization and the American Medical Association, private insurance companies rarely include coverage for infertility treatments. In this review, the authors assess the current state of care delivery for male infertility care in the United States. They discuss the scope of male infertility as well as the unique burdens it places on patients and review emerging market forces that could affect the future of care delivery for male infertility.

RESUMO

Infertility is a devastating experience for both partners as they try to conceive. Historically, when a couple could not conceive, the woman has carried the stigma of infertility; however, men and women are just as likely to contribute to the couple's infertility. With the development of assisted reproductive technology (ART), the treatment burden for male and unexplained infertility has fallen mainly on women. Equalizing this burden requires reviving research on male infertility to both improve treatment options and enable natural conception. Despite many scientific efforts, infertility in men due to sperm dysfunction is mainly diagnosed by a semen analysis. The semen analysis is limited as it only examines general sperm properties such as concentration, motility, and morphology. A diagnosis of male infertility rarely includes an assessment of internal sperm components such as DNA, which is well documented to have an impact on infertility, or other components such as RNA and centrioles, which are beginning to be adopted. Assessment of these components is not typically included in current diagnostic testing because available treatments are limited. Recent research has expanded our understanding of sperm biology and suggests that these components may also contribute to the failure to achieve pregnancy. Understanding the sperm's internal components, and how they contribute to male infertility, would provide avenues for new therapies that are based on treating men directly for male infertility, which may enable less invasive treatments and even natural conception.

RESUMO

PURPOSE: To determine whether the type of delivery system is associated with intensity of care at the end of life for Medicare beneficiaries with cancer. PATIENTS AND METHODS: We used SEER registry data linked with Medicare claims to evaluate intensity of end-of-life care for patients who died of one of ten common cancers diagnosed from 2009 through 2014. Patients were categorized as receiving the majority of their care in an integrated delivery system, designated cancer center, health system that was both integrated and a certified cancer center, or health system that was neither. We evaluated adherence to seven nationally endorsed end-of-life quality measures using generalized linear models across four delivery system types. RESULTS: Among 100,549 beneficiaries who died of cancer during the study interval, we identified only modest differences in intensity of end-of-life care across delivery system structures. Health systems with no cancer center or integrated affiliation demonstrated higher proportions of patients with multiple hospitalizations in the last 30 days of life (11.3%), death in an acute care setting (25.9%), and lack of hospice use in the last year of life (31.6%; all P < .001). Patients enrolled in hospice had lower intensity care across multiple end-of-life quality measures. CONCLUSION: Intensity of care at the end of life for patients with cancer was higher at delivery systems with no integration or cancer focus. Maximal supportive care delivered through hospice may be one avenue to reduce high-intensity care at the end of life and may impact quality of care for patients dying from cancer.

RESUMO

INTRODUCTION: Health care prices in the United States are often opaque to providers and patients while prices of nonhealth care services are displayed prominently across the Internet. Posting prices online will soon be a national requirement for hospitals, including for urological care. Male infertility care is rarely covered by insurance so many providers have developed cash prices to assist their patients. Expected success rate is also of interest to patients. The online availability of this information is unknown. METHODS: Membership databases of the Society for the Study of Male Reproduction and Society for Male Reproduction and Urology were searched to identify U.S. based clinical urologists. Websites were found with Google and analyzed for infertility services provided, prices and success rates. Specifically, websites were reviewed for information on any infertility care, vasectomy, vasectomy reversal, varicocele, sperm retrieval or microscopic testicular sperm extraction. RESULTS: A total of 222 individual providers were identified of which 204 had associated websites. Information about general male infertility services was readily available (85%), while specific procedures were described on 66% of websites or lower. Pricing information was available on 7.4% (15) of websites. Success rates were most frequently described for vasectomy reversal (23%). Pricing and success rates were more commonly found for private practice or personal websites. CONCLUSIONS: Pricing and success rates for male infertility are uncommonly listed on websites for U.S. male infertility providers. Several barriers may contribute including institutional policies and lack of physician input on website content. As pricing online becomes required, hospitals and likely urology practices will need to provide this information publicly.
