Naturally sterile Mus spretus hybrids are suitable for the generation of pseudopregnant embryo transfer recipients.

For the preparation of embryo transfer recipients, surgically vasectomized mice are commonly used, generated by procedures associated with pain and discomfort. Sterile transgenic strains provide a nonsurgical replacement, but their maintenance requires breeding and genotyping procedures. We have previously reported the use of naturally sterile STUSB6F1 hybrids for the production of embryo transfer recipients and found the behavior of these recipients to be indistinguishable from those generated by vasectomized males. The method provides two substantial 3R impacts: refinement (when compared with surgical vasectomy) and reduction in breeding procedures (compared with sterile transgenic lines). Despite initial promise, the 3Rs impact of this innovation was limited by difficulties in breeding the parental STUS/Fore strain, which precluded the wider distribution of the sterile hybrid. The value of a 3R initiative is only as good as the uptake in the community. Here we, thus, select a different naturally sterile hybrid, generated from strains that are widely available: the B6SPRTF1 hybrid between C57BL/6J and Mus spretus. We first confirmed its sterility by sperm counting and testes weight and then trialed the recovery of cryopreserved embryos and germplasm within three UK facilities. Distribution of sperm for the generation of these hybrids by in vitro fertilization was found to be the most robust distribution method and avoided the need to maintain a live M. spretus colony. We then tested the suitability of B6SPRTF1 sterile hybrids for the generation of embryo transfer recipients at these same three UK facilities and found the hybrids to be suitable when compared with surgical vasectomized mice and a sterile transgenic strain. In conclusion, the potential 3Rs impact of this method was confirmed by the ease of distribution and the utility of sterile B6SPRTF1 hybrids at independent production facilities.

FIELD TECHNIQUES FOR VASECTOMY IN BLACK HOWLER MONKEYS (ALOUATTA PIGRA).

Three adult black howler monkeys (Alouatta pigra) were vasectomized for the purpose of population control. Two different surgical approaches (inguinal and pelvic) were used to vasectomize the animals under general anesthesia. One monkey was vasectomized with a pelvic approach, and the other two monkeys were vasectomized with an inguinal approach. The inguinal approach was minimally invasive and proved to be an effective field procedure, utilizing minimal surgical equipment with a mean operative time of 35 min. The inguinal approach allowed for better visualization of the spermatic cord, which prompted easier ligation and transection of the ductus deferens. Identification of the ductus deferens was successfully performed intraoperatively using a tuberculin syringe to aseptically aspirate cord contents, as histopathology was not available. All howler monkeys fully recovered without complication. The social hierarchy of the troop and mating behavior has not been affected. There have been no new pregnancies reported in the troop since the vasectomies were performed. The inguinal approach is preferred as it is minimally invasive and can be performed confidently in a field setting.

Comparison of Childless and Partnerless Vasectomy Rates Before and After Dobbs v. Jackson Women's Health Organization.

The Supreme Court ruling Dobbs v. Jackson Women's Health Organization (June 2022) overturned federal protection of abortion rights, resulting in significant impact on both male and female reproductive rights and health care delivery. We conducted a retrospective review of all patients who underwent vasectomy at a single academic institution between June 2021 and June 2023. Our objective was to compare the rates of childless and partnerless vasectomies 1 year before and after this ruling, as these men may be more susceptible to postprocedural regret. Of total, 631 men (median age = 39 years, range = 20-70) underwent vasectomy consultation. Total vasectomies pre- and post-Dobbs were 304 (48%) versus 327 (52%). Total childless and partnerless vasectomies pre- and post-Dobbs were 44 (42%) versus 61 (58%) and 43 (46%) versus 50 (54%). Vasectomy completion rate was slightly increased post-Dobbs (90% vs. 88%; p = .240). The post-Dobbs cohort had significantly less children (1.8 vs. 2.0; p = .031). Men in the post-Dobbs era were significantly more likely to be commercially insured (72% vs. 64%) and less likely to be uninsured (1% vs. 6%; p = .002). Men who underwent childless vasectomy were significantly more likely to be younger (36.4 vs. 39.8 years; p < .001). There was a significantly greater proportion of Hispanic and Black men in the partnerless cohort compared to the cohort with partners (24% vs. 19% and 9% vs. 2%; p = .002). In conclusion, patients should be counseled on the permanent nature of this procedure, underscoring need for effective and reversible male contraception.

How to plan and provide general anesthesia for a troop of 98 hamadryas baboons (Papio hamadryas) for contraceptive and preventative health interventions.

OBJECTIVE: Present an approach to the safe and efficient provision of anesthesia and birth control measures to a large group of primates. ANIMALS: 98 hamadryas baboons (Papio hamadryas) held in a German zoological institution. METHODS: A group of 12 veterinarians, 2 zookeepers, and 6 volunteers anesthetized all animals within 2 days. The baboons were orally premedicated with midazolam (0.1 to 0.5 mg/kg) and anesthetized with medetomidine (40 to 60 µg/kg, IM) and ketamine (2 to 4 mg/kg, IM); isoflurane at rates of 1.5% to 2% was used for maintaining anesthesia if necessary. All animals received a physical examination, prophylactic medication, and tuberculin testing. For population management, the animals received a contraceptive implant (adult females), orchiectomy (young males), or vasectomy (breeding males). Young males received intratesticular blocks with lidocaine. All animals received atipamezole (125 to 150 µg/kg) before recovery. RESULTS: Premedication resulted in anxiolysis, which facilitated separating and darting. Median time from darting to access to the animal was 10 minutes. Mean anesthetic times were 25 minutes for females and 55 minutes for males. The depth of anesthesia was appropriate for the procedures. No fatalities were recorded. One animal was injured by other baboons but recovered after treatment. CLINICAL RELEVANCE: Health management and birth control measures are necessary in baboon troops under human care. Anesthesia and/or contraception of individual animals often leads to intraspecific aggression. This case series describes how to provide anesthesia and contraception to an entire troop as an alternative approach that can be adopted to future similar interventions.

High variability in self-pay pricing for vasectomy and vasectomy reversal in the United States.

CONTEXT: In the United States (US) men who undergo vasectomy and/or vasectomy reversal (vasovasotomy) are likely to pay out-of-pocket for these procedures. We characterized the publicly disclosed pricing of both procedures with a focus on variability in self-pay prices. METHODS: We queried all US hospitals for publicly disclosed prices of vasectomy and vasovasotomy. We assessed interhospital variability in self-pay pricing and compared hospitals charging high (≥75th percentile) and low (≤25th percentile) self-pay prices for either procedure. We also examined trends in pricing after the 2022 US Supreme Court decision that allowed individual states to ban abortion. RESULTS: Of 6692 hospitals, 1375 (20.5%) and 281 (4.2%) disclosed self-pay prices for vasectomy and vasovasotomy, respectively. There was a 17-fold difference between the 10th and 90th percentile self-pay prices for vasectomy ($421-$7147) and a 39-fold difference for vasovasotomy ($446-$17,249). Compared with hospitals charging low (≤25th percentile) self-pay prices for vasectomy or vasovasotomy, hospitals charging high (≥75th percentile) prices were larger (median 150 vs. 59 beds, p < 0.001) and more likely to be for-profit (31.2% vs. 7.8%, p < 0.001), academic-affiliated (52.7% vs. 23.1%, p < 0.001), and located in an urban zip code (70.1% vs. 41.3%, p < 0.001). From October 2022 to April 2023, the median self-pay price of vasectomy increased by 10% (from $1667 to $1832) while the median self-pay price of vasovasotomy decreased by 16% (from $3309 to $2786). CONCLUSION: We found large variability in self-pay pricing for vasectomy and vasectomy reversal, which may serve as a barrier to the accessibility of male reproductive care.

Vasectomy: An increasingly common procedure in France.

OBJECTIVES: To analyze the evolutionary trends concerning vasectomy over the last 8 years in order to better understand the situation and identify measures to be implemented to develop this activity. METHODS: The number of vasectomy procedures performed between 2015 and 2022 was extracted from the Open CCAM file compiled from the national database of the Programme de médicalisation du système d'informations français (PMSI). RESULTS: Over the period 2015-2022, the number of vasectomy procedures increased from 3743 in 2015 to 29,890 in 2022. This increase was observed in all French metropolitan and overseas regions. The number of minimally invasive vasectomies (notably without scalpel) rose sharply, from 313 to 7760. Almost all vasectomies were performed during outpatient hospitalization (0 nights), with fewer than 300 acts reported/year in outpatient care. CONCLUSION: In France, vasectomy is becoming an increasingly frequent contraceptive method. This analysis is in line with recent surveys carried out in France, and tends to prove that more and more couples of childbearing age are in favour of sharing the contraceptive burden.

Dynamism of andrological surgery in France: Evolution of procedures over 10 years.

INTRODUCTION: Andrology and urogenital reconstruction are emerging disciplines in French urology. The aim of our study was to evaluate the evolution of andrological surgical procedures over the period 2013-2022 using national data. MATERIALS AND METHODS: We collected national common classification of medical acts (CCAM) coding data for all procedures involving andrological surgery from the Scansanté internet platform set up by the Technical Agency for Information on Hospitalisation, which collects prospectively from healthcare structures all procedures coded according to CCAM coding. All surgical procedures in andrology were selected. The inclusion period extended from 2013 to 2022. RESULTS: In 10 years, the number of vasectomies has increased tenfold, with 29,890 cases in 2022. Vaso-vasostomies remain marginal, with 80 cases per year. Trans-identity surgeries are rising sharply. Vaginoplasties have multiplied by 4 (333 in 2022) and masculinising surgeries have multiplied by 10 (234 in 2022). Penile prosthesis surgery has increased slightly over 10 years. The number of testicular biopsies has remained stable over time, as has the number of surgeries for curvature of the penis. CONCLUSION: Two andrological surgeries are showing very strong growth: vasectomy and transgender surgery. The emergence of these 2 activities is linked to societal aspirations. Urologists need to be trained to meet this demand. NIVEAU DE PREUVE: Grade 4.

Seminoperitoneum in a Dog with a History of a Vasectomy: Case Report.

An 8 yr old male German shorthaired pointer was presented on July 4, 2022, for acute abdominal and testicular pain. The dog was vasectomized at an unknown age under the care of his previous owners. The dog had an enlarged, painful left testis, scrotal edema, and an enlarged, nonpainful prostate. Abdominal ultrasound revealed mild peritoneal and retroperitoneal effusion, orchiepididymitis, enlarged ductus deferentes and testicles, and suspected benign prostatic hyperplasia versus prostatitis. Peritoneal effusion cytology revealed seminoperitoneum with marked neutrophilic inflammation. Peritoneal effusion aerobic culture and Brucella canis rapid slide agglutination test were negative. The dog was hospitalized overnight with IV antibiotic therapy and analgesics. The following day, the dog's abdominal pain, testicular pain, and scrotal edema were resolved. The dog was discharged and castrated after completion of antibiotic therapy and complete resolution of clinical signs. Testicular histopathology results were not available. Seminoperitoneum is uncommon in dogs and is a rare diagnosis for dogs with acute abdominal pain. This is the second known reported case of a seminoperitoneum in a vasectomized dog.

[The sociological approach to vasectomized patient trajectories at the Buenos Aires University Clinical Hospital "José de San Martín"].

According to the Argentinian Ministry of Health records the number of patients requesting vasectomy increased twelve times in public hospitals in 2015-2019. The physicians and specialists account for this change in recent years, arguing, among other reasons, cultural change when male assumes active position in contraceptive methods. The article addresses vasectomized patient trajectory at the Buenos Aires University Clinical Hospital "José de San Martín". The purpose of the study was to define from sociological point of view if we are actually witnessing cultural change. While considering last ten years (2012-2022), through diachronic analysis of patient demand at the Male Fertility Laboratory (n=1136) it was found that although main motivation is fertility, minority (6%) consulting to confirm absence of sperm in the ejaculate following vasectomy increased significantly in 2022 (Pearson's chi-squared test p<0.0001). After qualitative/quantitative interviews of former patient group (n=36) two sub-populations were distinguished: childless (42%; Median age: 30 years old; range: 24-35) and those having a family (58%; Median age: 39 years old; range: 35-54). Most of them had University degree (67%) and learned about this anti-contraceptive method by the Internet. It is remarkable that 94% of them were not aware of the the Argentinian Law № 236139 of 2006 that grants their right to vasectomy. Among all patients randomly interviewed in 2022 (n=200) condom anti-contraceptive method was the best known (67%). The conclusion was made that in the meantime developed New Trend that comprises high educational level segment of population of Argentina that in the future can become the germ of Cultural Change encompassing the whole society.

Permanent and long-acting reversible contraception volumes at a multihospital system in Ohio before and after Dobbs.

OBJECTIVES: Immediately following the Dobbs decision, Ohio prohibited abortion after the detection of fetal cardiac activity. We aimed to characterize changes in the uptake of long-acting reversible contraception (LARC) and permanent contraception following the abrupt enactment of restrictive abortion legislation. STUDY DESIGN: We conducted a retrospective cohort study using electronic medical record data of patients aged 15 to 55 who underwent permanent contraception (tubal ligation, vasectomy) or LARC placement (intrauterine device, contraceptive implant) at a multihospital system in northeast Ohio from January 1, 2022 to Decemeber 31, 2022, 6 months before and after Dobbs. We compared procedure volumes and patient characteristics. RESULTS: We identified 4247 tubal ligation and LARC procedures pre-Dobbs, including 725 (17.1%) permanent contraception and 3522 (82.9%) LARC. Post-Dobbs, the total number of tubal ligation and LARC procedures increased by 15.8% (4916), and there was a significant increase in the proportion of permanent contraception, (p < 0.001). Vasectomy volume increased by 33.3% post-Dobbs, from 1193 to 1590 procedures. Compared to pre-Dobbs, patients undergoing contraceptive procedures post-Dobbs were younger (tubal ligation and LARC, 30.9 median years [24.5, 36.8] vs 31.5 [25.2, 36.9], p = 0.011; vasectomy, median 36.6 years [32.9, 39.6] vs 37.2 [34.2, 40.4], p < 0.001) and more likely to report single relationship status (57.4% vs 55.9% for tubal ligation and LARC, p = 0.028% and 23.0% vs 18.1% for vasectomy, p = 0.002). CONCLUSIONS: This study demonstrates increased uptake of contraceptive procedures following the Dobbs decision. This rise in permanent contraception suggests a relationship between abortion policy and contraceptive decision-making, especially among younger patients. IMPLICATIONS: Increased permanent and long-acting reversible contraception procedures following Dobbs reveal shifting contraceptive choices, particularly among younger individuals, indicating a connection between abortion policy and reproductive decisions.

Trends in vasectomy and sexually transmitted diseases in Chile: findings from robust national databases.

A controversy about the increase or decline of vasectomy is emerging; however, the evidence is still scarce in Latin America. This ecological study analyzed the vasectomy and sexual transmitted diseases (STD) trends over a period of 10 years in Chile and determined if there is any relationship between them. We conducted a mixed ecological study using secondary and representative data on the number of vasectomies and STD cases from 2008 to 2017. Vasectomy rates were calculated for age-specific groups of men aged 20-59 years, and specific STD (HIV, chlamydia, gonorrhea, trichomoniasis, and syphilis) for the same period. Multivariate negative binomial regression models were fitted to evaluate rate trends and relationships. The mean vasectomy age was 40.3 years, with no significant differences between the years of the study (p = 0.058). The overall vasectomy rate significantly increased from 2008 to 2017 (p < 0.001), with differences between age groups (p < 0.001). The most significant increase was observed in men aged 30-49 (p < 0.001). The STD rates significantly increased (p < 0.05) during the study period. A significant positive correlation was found between vasectomy and gonorrhea incidence rates (p = 0.008) and an inverse correlation was found with hepatitis B incidence rates (p = 0.002). Vasectomy trends and STD rates significantly increased from 2018 to 2017 in Chile. especially among men aged 30-49 years. The relationship between vasectomy and STD increments suggests a new risk factor for reproductive and sexual health policies to aid controlling the HIV and STD epidemic.

Short-Term Changes in Vasectomy Consults and Procedures Following Dobbs v Jackson Women's Health Organization.

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.

Patient Portal Engagement Affects Postvasectomy Semen Analysis Completion.

OBJECTIVE: To identify factors that affect completion of postvasectomy semen analysis (PVSA) in men receiving telehealth prevasectomy counseling. Telehealth visits have become increasingly common for prevasectomy consultations. Prior studies have shown that men prefer telehealth vasectomy consultations over in-person options. Postvasectomy semen testing should be completed to confirm sterilization. METHODS: Three hundred and seventy-one men aged 19 and older who saw a single physician for a telehealth prevasectomy consultation and completed an in-office vasectomy were included in the study. Demographic information such as age, patient relationship status, and distance from the clinic were accessed via electronic medical record. Patients were assessed based on their engagement with electronic preprocedure instructions, and the primary outcome measured was completion of PVSA. RESULTS: 45.6% of men completed a PVSA. There was no significant difference in completion of the PVSA between those who opened their electronic instructions before their vasectomy and those who did not (46.1% vs 44.4%, P = .77). Of those who messaged the clinic for any reason at least once after their consultation, 62% completed their PVSA; 41% who did not contact the clinic completed the PVSA (P = .0009). CONCLUSION: While there was no difference in completion of PVSA in patients who opened their instructions vs those who did not, patients with a higher level of engagement with the patient portals were more likely to complete their semen test. By understanding factors influencing patient compliance with postvasectomy semen testing, healthcare professionals can develop targeted interventions to ensure safe and successful outcomes.

Antisperm Antibody Levels After Vasectomy Reversal Are Not Associated With Pregnancy Rates or Method of Conception.

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.

Vasectomy provider decision-making balancing autonomy and non-maleficence: qualitative interviews with providers.

Background: Male sterilization, or vasectomy, is 99.9% effective at preventing pregnancy with less than a 2% risk of complications. Despite the high efficacy, low risk, low cost, and gender equity benefits of vasectomy, just 2% of women reported that they and their partners relied on vasectomy as their contraceptive method globally in 2019. Health care providers can be both a facilitator and a barrier in men's health generally, and may be in vasectomy provision as well. This study sought to describe the decision-making rationales of experienced vasectomy providers when evaluating patient candidacy in complex cases. Methods: Fifteen vasectomy providers belonging to the global Vasectomy Network google group from seven countries participated in online interviews using a semi-structured in-depth interview guide. Providers were asked about their vasectomy training, their reasons for vasectomy provision, challenging cases they have faced, and approaches used to manage challenging cases. Vignettes were used to further elicit decision-making rationale. Thematic analysis was conducted using MAXQDA20. Results: Provider decision-making was predicated on ensuring patients were well-informed, able to consent, and certain about their choice to have a vasectomy. Once those foundational conditions were met, providers filtered patient characteristics through their training, laws and policies, sociocultural norms, experience, and peer influence to produce a cost-benefit breakdown. Based on the cost-benefit analysis, providers determined whether to weigh autonomy or non-maleficence more heavily when determining vasectomy patient candidacy. Conclusions: Despite clinical best practices that promote prioritizing patient autonomy over non-maleficence, some providers continued to weigh non-maleficence over autonomy in vasectomy patient candidacy evaluations. Non-maleficence was particularly prioritized in cases providers deemed to be at higher risk of regret. The findings of this study suggest vasectomy provider training should emphasize evidence-based best practices in shared decision-making and patient-centered care to facilitate vasectomy provision that honors patient autonomy and rights.
