Trends in the Vasectomy Rate Among Privately Insured Men Aged 18-64 in the United States Between 2014 and 2021.

OBJECTIVE: To update trends in the vasectomy rate among privately insured men aged 18-64 in the United States (U.S.) between 2014 and 2021. MATERIALS AND METHODS: We used commercial health insurance claims data between 2014 and 2021 to calculate the annual vasectomy rate in men aged 18-64 in the U.S. We performed these calculations nationally and by age group, marital status, maternal age of a wife, number of children, U.S. Census Bureau region, geography, geographical region, and state. We calculated the absolute and relative changes in these rates from 2014 to 2021 to study how much and how quickly they changed. RESULTS: The vasectomy rate among privately insured men aged 18-64 in the U.S. increased by 0.11%-a 26% change-from 2014 (0.427%) to 2021 (0.537%). The absolute changes were greatest in men with 3 or more children (0.489%), with 2 children (0.295%), with a wife not of advanced maternal age (0.276%), and aged 35-44 (0.243%). The relative changes were greatest in men with no children (61%), with a wife of advanced maternal age (40.8%), who were single (40.6%), and aged 18-24 (36.7%). In every region except the Northeast, the absolute and relative changes were greater in rural geographies compared to urban geographies. CONCLUSIONS: The vasectomy rate among privately insured men aged 18-64 in the U.S. increased between 2014 and 2021. Further investigation is needed to ensure demand for vasectomies may continue to be met.

Vasectomy utilization in men aged 18-45 declined between 2002 and 2017: Results from the United States National Survey for Family Growth data.

BACKGROUND: Vasectomy remains a safe, simple, and effective contraceptive option. Conflicting data on the trend of vasectomy use among men have been described previously at various snapshots in time over the last two decades. OBJECTIVES: This paper seeks to describe the trend of vasectomy utilization in the last 15 years using a nationally representative US survey. MATERIALS AND METHODS: We analyzed data from male respondents aged 18 to 45 years of the Cycle 6 (2002), 2006-2010, 2011-2013, 2013-2015, and 2015-2017 National Survey of Family Growth (NSFG) surveys. Population estimates are calculated based on the official NSFG instructions, accounting for the complex survey design. Multivariate logistic regression models are used to study demographic and socioeconomic factors associated with vasectomy use in men. RESULTS: Baseline characteristics for men undergoing vasectomy do not differ significantly across survey years. Increased age, White race, marital status, higher education level, birthplace within the United States, higher household income, non-Catholic affiliation, and higher number of biological kids have significant positive associations with vasectomy use. After accounting for factors associated with vasectomy utilization, there was a significant temporal decline in vasectomy utilization rates in all age groups across survey years which remained in subgroup analyses of all men greater than 25, 30, and 35 years of age. DISCUSSION: This is the first population-based analysis of US data to observe a decline in vasectomy utilization over the past two decades. The decline was statistically significant after accounting for all demographic and socioeconomic factors. CONCLUSION: There is a steady decline in the prevalence of vasectomy use in men from 2002 to 2017. Given the limited contraceptive options for men and the importance of contraception and family planning in the United States, further research is needed to understand the temporal decline.

National Characteristics of Surgeons Performing Vasectomy: Increasing Specialization and a Persistent Gender Gap.

OBJECTIVE: To describe trends in the characteristics of urologic surgeons performing vasectomy over time. METHODS: We performed a retrospective, cross-sectional study examining surgeon characteristics for case logs from the American Board of Urology between 2004 and 2013. We used generalized estimating equations with a log link and negative binomial distribution to examine demographic differences (gender, rural location, and surgeon volume) in the number of vasectomies surgeons performed over time. RESULTS: Between 2004 and 2013, 5316 urologists had case logs collected within the 7-month certification window. The majority of these surgeons self-identified as general urologists (82.8%), and a small proportion identified as andrology and infertility specialists (1.7%). Across all years, the median number of vasectomies performed per certifying surgeon during the study period was 14 (interquartile range 6-26). The majority of vasectomies were performed by high-volume surgeons (≥ 26 vasectomies) ranging from 49.2% to 66.9% annually, whereas the proportion performed by low-volume (≤ 5 vasectomies) surgeons ranged from 3.3% to 6.6% annually. Male surgeons performed vasectomies 2.20 times more frequently than female surgeons (95% confidence interval 1.93-2.49; P <.0001) across the study period with no evidence to suggest this gap changed over time (gender-year interaction 1.01 [95% confidence interval: 0.97-1.06; p = .576]). CONCLUSION: While the majority of urologists performing vasectomy identify as general urologists, there appears to be a focus on vasectomy practice among a small number of high-volume surgeons. Furthermore, while the number of female surgeons performing vasectomies increased, a gender gap persists in the proportion of vasectomies performed by females.

Original investigations into the clearance of spermatozoa after vasectomy.

"The urologist and patient, with the cooperation of the laboratory performing the sperm counts, can determine within a few days after operation that aspermia has been produced and that the procedure has been successful." -Freund M, Davis JE.

Evaluation of Vasectomy Trends in the United States.

OBJECTIVE: To use the Truven Health MarketScan database to better approximate the annual rate of vasectomies performed in the US population, to determine changes over time, regional differences, providers performing this, and to know if there is any monthly variation in vasectomy rates. MATERIALS AND METHODS: Claims data were evaluated from 2007 to 2015 to determine the annual prevalence of vasectomy by patient age and region in the United States. The cohort included men aged 18-64 years with at least 1 claim in any given year in Truven Health MarketScan. Provider type and place of service were evaluated in 2014 and 2015. Monthly evaluation of vasectomy prevalence compared with total claims was performed. RESULTS: The prevalence of vasectomies decreased from 2007 to 2015, across all age groups and in all locations of the country (P <.001). Using these data and the most recent US census data, an estimated 527,476 vasectomies were performed in the United States in 2015. The North Central and West regions (0.64% and 0.60%, respectively) had the highest annual prevalence of vasectomies. The month of March and the end of the year had the highest proportion of vasectomies performed. In both 2014 and 2015, a urologist in the office setting performed 82% of vasectomies. CONCLUSION: An estimated 527,476 vasectomies were performed in the United States in 2015. From 2007 to 2015 there was a decrease in the proportion of vasectomies performed in all age groups and in all locations of the country. The end of the year and the month of March are when the most vasectomies are performed.

Novel restricted access to vasectomy in Iran: addressing changing trends in vasectomy clients' characteristics over 16 years in northwestern Iran.

OBJECTIVES: This study is designed to evaluate the popularity of vasectomy in Iran. The study was conducted to calculate the frequency of vasectomy over time, to compare vasectomy users' characteristics with the general population and whether these characteristics have changed over time. STUDY DESIGN: A cross-sectional study of 7864 men undergoing vasectomy in a 16-year period was conducted in Urmia, Iran. Comparative statistics described differences between vasectomy users and nonusers. The data were analyzed separately in two 8-year periods, 1996-2003 and 2004-2011. The time period did not involve 2012, the year which vasectomy became outlawed in the whole country. RESULTS: During the study period, the contraceptive prevalence rate of vasectomy increased from 0.1% to 3.35%. Vasectomy users were predominantly older, better educated, had more children and more urban residents than the general male population (p<0.001). Over time, men who underwent vasectomy tended to be younger, have well-educated wife and rural resident (p<0.05). CONCLUSIONS: This study highlighted a dramatic rise in the use of vasectomy between 1996 and 2011 in Iran. While the characteristics of vasectomy users versus general population were different, especially in age, education, resident area, number and sex of their children, there were significant changes from two 8-year study time periods.

Interest in nonsurgical female permanent contraception among men in Portland, Oregon and eastern Maharashtra, India.

OBJECTIVE: We examined the men's attitudes and perceptions toward the concept of female nonsurgical permanent contraception (NSPC) or novel approaches to permanent contraception (PC) that do not require incisions or surgical equipment/hysteroscope. STUDY DESIGN: Cross-sectional survey of married/partnered men in Portland, OR, and rural eastern Maharashtra, India. Descriptive analysis was performed. RESULTS: In India (N=150), most men (80%) anticipated that their partners would undergo PC in the future, compared to 30% in Portland (N=170). About a third (39.6% in India, 82% in Portland) reported being uncomfortable with PC for partners due to the need for surgery. Most men (85% in India, 82% in Portland) expressed a preference for a hypothetical new method of female NSPC over surgery, if safe and effective. CONCLUSION: Most men sampled in two diverse settings expressed interest in NSPC for women. IMPLICATIONS: Men's perceptions of new female contraceptive methods are important to the contraceptive development process. Men may find a safe and effective nonsurgical method of permanent female contraception more acceptable than surgical PC.

Male contraception: past, present and future.

Current contraceptive options available to men include withdrawal, condoms, and vasectomy, each of which has its own drawbacks. In this chapter we will describe the pros and cons for each, as well as methodological and product updates. Statistics from the U.S. Centers for Disease Control on acceptance and satisfaction will be included. Advances in vasectomy and reversal will be presented. Methods to develop new contraceptive technologies fall into two categories: hormonal and non-hormonal. Many targets and strategies have been proposed for non-hormonal male contraception within the testis. Targets include structural components in the testis, as well as enzymes, ion channels and other proteins specific to spermatozoa. Here we provide an overview of the spermatogenic mechanisms and proteins that have received research interest to date. We also discuss potential novel targets, such as ubiquitin specific proteases, that warrant greater research emphasis.

Vasectomia laparoscópica em macacos-prego (Cebus nigritus) / Laparoscopic vasectomy in nail-monkeys (Cebus nigritus)

This study aimed to evaluate the technique of laparoscopic vasectomy in nail-monkeys (Cebus nigritus). Therefore eight animals were subjected to inhalation anesthesia. Three portals (two 5mm and one 10mm) were positioned in the ventral abdominal wall. Vasa deferentia were isolated and cauterized by bipolar energy, and afterword sectioned near the internal inguinal ring. The procedures lasted 30.67+8.78 minutes without complications. It could be conclude that the proposed technique is suitable for this animal species.

Trend, client profile and surgical features of vasectomy in Ghana.

OBJECTIVE: To examine the socio-demographic and reproductive characteristics of vasectomy acceptors and surgical features of vasectomy in Ghana. METHODS: Retrospective review of 271 vasectomies performed between 1 January 2000 and 31 December 2009 in three healthcare facilities. RESULTS: Less than 0.5% of family planning clients opt for vasectomy in Ghana; acceptors are both professional and semi-skilled workers. The mean age of vasectomy acceptors was 40.7 years, and their mean number of children four. All clients had two children or more; there was a trend towards a greater number of children with increasing age (p trend <0.001) or a lower educational level of the clients (p trend =0.01). Most clients obtained their information on vasectomy through the media and healthcare workers. Nearly all vasectomies were performed under local anaesthesia using the no-scalpel technique. The operating time of gynaecologists was significantly shorter than that of urologists (median operating time 10 minutes vs. 25 minutes; p <0.001). The reported vasectomy failure rate was about 1%. CONCLUSIONS: The prevalence of vasectomy is low in Ghana. The factors influencing utilisation of male sterilisation services must be identified in order to improve uptake of this method of contraception in the country.

Factors influencing the declining trend of vasectomy in Sichuan, China.

Vasectomy was once the most common birth control method in both Sichuan Province, China and the world. However, since the 1990s the prevalence of vasectomy in Sichuan, has declined significantly compared to female sterilization in Sichuan and national prevalence of male/female sterilization during the same period. To explore possible reasons for this decline, 27 focus group discussions (FGDs) and 8 in-depth interviews (IDIs) were conducted in four strata of Sichuan. Procedures for qualitative data analysis were used. The findings reveal the decline in vasectomy in Sichuan Province is influenced by multiple factors, including shifts in demographics, changes in family planning working approach and people's perceptions of reproduction, lack of information and misunderstandings about vasectomy, the stereotype of male dominance, bias and preference of program and provider, and the impact of a market economy. Several implications arise from the study for future program development.

Update on male hormonal contraception: is the vasectomy in jeopardy?

Traditionally, male contraception has consisted of either barrier methods, such as condoms, or vasectomy. However, in recent years, we have made great strides in the basic science and clinical medicine to better understand the feedback mechanisms and physiology of the male reproductive system. These advances have enabled the development of several nonsurgical, hormonal, reversible, well-tolerated alternatives for male contraception. Men are more likely now than ever to participate in the choice of contraceptive techniques. This review will discuss the current status and recent developments in nonsurgical hormonal male contraception, a field that has been historically limited by social, financial and physiological challenges.

Demographics of vasectomy--USA and international.

Vasectomy is safer, simpler, less expensive, and equally as effective as female sterilization--yet it remains one of the least known and least used methods of contraception. Worldwide, an estimated 33 million of married women ages 15 to 49 (less than 3%) rely on their partner's vasectomy for contraception.

Vasectomia sem bisturi - experiência ambulatorial / No-scalpel vasectomy - out-patient experience

Projeto piloto, não-comparativo para avaliar a experiência regional da vasectomia sem bisturi como um método contraceptivo permanente em um serviço de planejamento familiar, em nível ambulatorial, que poderia ser realizada por ginecologistas e médicos generalistas. Métodos: O estudo foi realizado no Serviço de Planejamento Familiar do Hospital Municipal de Ituiutaba, Minas Gerais, em convênio com o Departamento de Ginecologia e Obstetrícia da Universidade Federal de Minas Gerais, aprovado pelo Conselho de Ética daquele Hospital. Após ações educativas sobre todos os métodos contraceptivos, escolha espontânea do método pelo casal com assinatura de consentimento pós-informado, foram submetidos à vasectomia 181 pacientes com a idade variando de 25 a 52 anos, em um período de dois anos. Os procedimentos foram realizados em regime ambulatorial. Dos 181 casos operados, houve um caso de reanastomose espontânea que foi submetido à nova cirurgia, dois pacientes apresentaram epidimites que foram resolvidas com antibióticos e um caso de pequeno hematoma, que solucionou espontaneamente. Conclusão: A vasectomia sem bisturi demonstrou ser um método seguro, simples, com boa aceitabilidade, apresentando pequenos índices de falhas e de complicações que pode ser realizada por ginecologistas ou médicos generalistas num ambiente de ambulatório.

A 15-year longitudinal analysis of trends in elective urological surgery - an evidence base for Modernising Medical Careers.

INTRODUCTION: The impact of Modernising Medical Careers on the differential need for consultant urologists and urological surgeons is as yet unknown. This study's aim was to determine what changes there had been in operative urological activity so as to predict the need for urological surgeons in the future. MATERIALS AND METHODS: A retrospective study of all elective operative urological surgery over a 15-year period was performed. The absolute numbers of patients presenting for different grades of surgery were aggregated and analysed using the Spearman's rank correlation test. RESULTS: Aggregated data from 27,839 procedures demonstrated no change in the number of operations (r 0.01; NS) or the number of diagnostic endoscopic procedures (r 0.21; NS) carried out over the study period. There was a decrease in endoscopic surgery related to a 70% reduction in trans-urethral resection of the prostate (TURP) (r -0.89; P = <0.0001) and an increase in ureteroscopic interventions (r 0.82; P = 0.0002) for stone disease. There was no change in the amount of major surgery carried out (r -0.43; NS) over the 15 years. CONCLUSIONS: There have been changes to the pattern of surgery urologists have provided over the last 15 years but the need for complex surgical interventions has not altered. This suggests there will be as great a need for operating surgeons in the future, as currently exists.

[Vasectomy: indications and implementation in historic perspective]. / Vasectomie: indicaties en uitvoering in een historisch perspectief.

Approximately 35,000 vasectomies were performed in the Netherlands in 2004. Although vasectomy may be looked upon as the most reliable method of contraception (risk of pregnancy in the first year: 0.08-0.15%), realistic preoperative counselling about possible complications such as haemorrhage (5%), wound infection (5%), and haematoma (14%) and long-term consequences such as the wish for renewed fertility (2.6% of the men opt for vasectomy reversal), the delayed achievement of sterility (4% three months after vasectomy), chronic scrotalgia (5%) and the risk of recanalisation (0.28-00.5%) is of utmost importance. Moreover, the couple should be convinced that vasectomy can only be considered successful if less than 100,000 non-motile sperms per ml are demonstrated by a certified laboratory in a post-vasectomy semen analysis. As an alternative for vasectomy, several clinical studies to assess the value of male hormonal contraception are currently in progress.
