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

Temporal trend of vasectomies in Brazil and its regions by age group and race/skin color: a temporal analysis from 2013 to 2022

OBJECTIVE

To analyze the temporal trend of vasectomies in Brazil and its regions by age group and race/skin color from 2013 to 2022.

METHODS

This is a time series analysis study based on Hospital Information System data. Average annual percentage change (AAPC) and 95% confidence intervals (95%CI) of vasectomy coefficients were estimated using Joinpoint regression. Trends were compared using parallel testing and coincidence testing.

RESULTS

In the period, there were 309,047 vasectomies in Brazil and their trend was stationary (AAPC 5.57; 95%CI -1.08; 12.66), although there was a rising trend in the Northern region (AAPC 11.53; 95%CI 2.30; 21.59) and in the Northeast region (AAPC 8.90; 95%CI 1.94; 16.34). All races/skin colors showed rising trends. Men who were 50-54 years old (AAPC 8.69; 95%CI 1.14; 16.81) and 55-59 years old (AAPC 8.71; 95%CI 0.92; 17.10) had the highest AAPC as well as rising trends. There were differences in trends, especially between age groups.

CONCLUSION

Vasectomy trends varied across Brazil, highlighting regional, age and racial disparities related to this procedure.

Changes in male permanent contraception as partner access to long-acting reversible contraception (LARC) increases: an analysis of the National Survey for Family Growth, 2006-2010 versus 2017-2019

OBJECTIVE

Male permanent contraception (PC), that is, vasectomy, is an effective way of preventing pregnancy. In the United States, male PC use has historically been concentrated among higher-educated/higher-income males of White race. In the last decade, use of long-acting reversible contraception (LARC) has increased dramatically. We sought to understand how sociodemographic patterns of male PC have changed in the context of rising LARC use.

STUDY DESIGN

We examined the nationally representative male public use files of the National Survey for Family Growth (NSFG) across five survey waves. Our outcome was primary contraceptive use at last sexual encounter within 12 months. Using four-way multinomial logistic regressions (male PC, female PC, LARC, lower-efficacy methods), we compared sociodemographic factors predictive of male PC use versus reported partner LARC use between 2006-2010 (early) and 2017-2019 (recent) waves.

RESULTS

We included 15 964 participants. From 2006 to 2019, there were absolute declines in male PC from 8.0% to 6.8%, while male-reported partner LARC use increased three-fold, from 3.4% to 11.0%. Among the highest economic strata, use of LARC converged with male PC. In adjusted analyses, high income significantly associated with male PC use in the early wave (OR 4.6 (1.4, 14.8)), but no longer in the recent wave (OR 0.9 (0.2, 4.2)). Marital status remained a significant but declining predictor of male PC across survey waves, and instead, by 2019, number of children newly emerged as the strongest predictor of male PC use.

CONCLUSION

Sociodemographic variables associated with vasectomy use are evolving, especially among high-income earners.

Decomposition analysis of racial and ethnic differences in receipt of immediate postpartum, long-acting, reversible, and permanent contraception

OBJECTIVES

This study aimed to determine the factors contributing to racial and ethnic disparities in the use of immediate postpartum, long-acting reversible contraception (IPP LARC) and permanent contraception among Medicaid recipients.

STUDY DESIGN

We conducted a cross-sectional study using 3 years of national Medicaid claims data to examine the rates of IPP LARC use alone and a composite measure of postpartum permanent contraception and IPP LARC within 7 days of delivery by race and ethnicity. We used a Blinder-Oaxaca model to quantify the extent to which medical complexity, age, rurality, mode of delivery, and year explained differences in outcomes among different minoritized groups in comparison to non-Hispanic White women.

RESULTS

Our study sample contained 1,729,663 deliveries occurring from 2016 through 2018 among 1,605,199 people living in 16 states. IPP LARC use rates were highest among Black (2.2%), followed by American Indian and Alaska Native at 2.1% and Hawaiian/Pacific Islander beneficiaries at 1.9%, Hispanic (all races) at 1.2%, and Asian at 1.0%. IPP LARC was lowest among White beneficiaries (0.8%). Medical complexity, age, rurality, year, and mode of delivery explained only 12.3% of the difference in IPP LARC rates between Black and White beneficiaries. Postpartum permanent contraception was highest among White (7.6%), Hispanic (7.2%), and American Indian and Alaska Native (6.8%), followed by Black (6.3%), Hawaiian/Pacific Islander (5.1%) and lowest among Asian women (4.1%). When we examined the use of IPP LARC or postpartum permanent contraception together, these same factors explained 94.4% of the differences between Black and White beneficiaries.

CONCLUSIONS

While differences in the use of IPP LARC by race and ethnicity were identified, our findings suggest that overall use of inpatient highly effective contraception are similar across racial and ethnic groups.

IMPLICATIONS

When IPP LARC and postpartum permanent contraception are examined jointly, their use is similar across racial and ethnic groups.

Male contraceptive acceptability versus male acceptance of contraceptive responsibility

Despite the projected impact of new male contraceptives, resources and investments directed at their development remain limited in part due to concerns that men would not actually use them. Now, more than 30 studies have been conducted over the last 30 years-regionally and internationally, within clinical trials, and across populations-examining men and women's attitudes towards new male contraceptive methods, all consistently demonstrating interest in and willingness to use new methods. Yet even these studies, inclusive of competitive contraceptive market projections, seem not to be convincing enough. Rather than study whether men would be willing to use male contraceptives, more resources should be devoted to developing the infrastructure and supporting the cultural changes needed to ensure that when new male contraceptives inevitably emerge, that they will be disseminated quickly and made readily accessible. Men's views on what their roles are in society, families, relationships, and pregnancy prevention are changing in ways that may impact what they consider to be acceptable contraceptive risks. As society moves toward more gender equitable beliefs, men's positive involvement in contraception might organically develop into an expected behavior. Interventions aimed at sensitizing men toward gender equitable beliefs may pay dividends in improving male contraceptive acceptability. The current lack of a reversible male contraceptive method prevents us from collecting data that might disprove presumptions that men would be unwilling to take on responsibility for pregnancy prevention. However, studies of men's involvement in (1) over-the-counter emergency contraception, (2) vasectomy, and (3) abortion offer case studies for men's increasing consciousness of opportunities for shared contraceptive responsibility, the structural and sociopolitical barriers that men face when trying to participate in family planning, and how these might translate into new male contraceptive interest and development.

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.

Patient perspectives on vasectomy: findings from a TikTok® content analysis

Social media is increasingly used as a platform for patients to explore health care information. Our objective was to study the content on TikTok® in order to gain insight into the perspectives shared by the public on vasectomy. A search was performed using the hashtag ´#vasectomy´ on 12.20.2023 and the top 100 video posts from persons self-identifying as patients were included. Using an adaptation of a previously published system, a framework was created for organising and categorising the data related to vasectomy. Domains covered included reason for vasectomy, complications, vasectomy as a controversial topic in society and reference to the 2022 Dobbs v. Jackson ruling. Most content originated from the United States (85.0%) and the median number of views per video was 261 200 (interquartile range (IQR) 8416-1 800 000). In 12.0% of posts, the individual clearly stated that they were under 30 years of age. Two of the commonest topics to be addressed in the videos were recovery (41.0%) and pain (40.0%). 30.0% discussed the reason for undergoing vasectomy. Reasons included women's rights (12%), safety over tubal ligation (5.0%) and desire to be childless (4.0%). 9.0% referred to the Dobbs v. Jackson ruling. Complications were discussed in 19.0% including vasectomy failure (12.0%). 23.0% contained factually incorrect medical information. 31.0% of videos included the user voicing that vasectomy was considered to be a controversial subject. More than half of the videos (61.0%) were positive regarding the vasectomy process. Our findings reveal that vasectomy receives very high engagement on social media. This study confirms that patients do use it to share their experiences, both positive and negative. Misconceptions regarding this contraception method are common among the public and the urological community should work to address this.

Vasectomy incidence in the military health system after the reversal of Roe v. Wade

Dobbs v. Jackson Women's Health Organization (Dobbs decision) has already had profound impact on reproductive health care in the United States. Some studies have reported increased incidence of vasectomy after the Dobbs decision. The Military Health System (MHS) provides a unique opportunity to evaluate this relationship in a universally insured, geographically representative population. We conducted a retrospective cross-sectional study of vasectomies among all male beneficiaries in the MHS, ages 18 to 64, from 2018 to 2022. Beneficiaries receiving a vasectomy were identified via billing data extraction from the MHS Data Repository (MDR). Descriptive statistics of demographic factors of all those receiving a vasectomy in the study period were evaluated. Crude and multivariate logistic regression models were used to evaluate for differences in demographic variables in those receiving a vasectomy pre-Dobb's decision as compared to after the Dobb's decision. The total number of men receiving a vasectomy each month over the study period was analyzed, as were the numbers in a state immediately implementing abortion access restrictions (Texas), and one without any restrictions on abortion access (Virginia). Our analysis found that men receiving a vasectomy post-Dobbs decision were more likely to be younger, unmarried, and of junior military rank than prior to the Dobbs decision. In the months following the Dobbs decision in 2022 (June-December), there was a 22.1% increase in vasectomy utilization as compared to the averages of those months in 2018-2021. Further, it was found that the relative increase in vasectomy after the Dobbs decision was greater in Texas (29.3%) compared to Virginia (10.6%). Our findings highlight the impact of the Dobbs decision on reproductive health care utilization outside of abortion.

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.

The percentage of men counseled by urologists who received a vasectomy mildly increased after the publication of the AUA vasectomy guideline

This retrospective cohort study explored whether the publication of the vasectomy guideline by the American Urological Association in December 2012 increased the percentage of men counseled by urologists who received a vasectomy. We used commercial health insurance claims between 2010 and 2015 to identify the initial sterilization counseling visit for men aged 18-64 and whether each of them received a vasectomy within six months of that visit. A difference-in-differences analysis isolated the effect of the guideline on the percentage of men counseled by urologists who received a vasectomy, exploiting suspected variation in guideline exposure and adherence between urologists and non-urologists. In total, 226 012 men had an initial sterilization counseling visit, of which 182 204 (80.6%) were counseled by urologists and 43 808 (19.4%) were counseled by non-urologists. The percentage of men counseled by urologists who received a vasectomy mildly increased by 1.5% (p = 0.002) after the publication of the guideline. Therefore, the percentage of men who receive a vasectomy may in part be explained by practice guidelines and clinicians' willingness to consider the procedure, and future research should investigate how clinicians arrive at their decisions to recommend a vasectomy and whether a standardized counseling protocol would ensure consistency.

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.

Down But Not Out: Vasectomy Is Faring Poorly Almost Everywhere-We Can Do Better To Make It A True Method Option

INTRODUCTION

Demand for vasectomy-1 of 2 contraceptive methods for men-has been low, with deep-seated myths, misconceptions, and provider bias against it widespread. Programmatic attention and donor funding have been limited and sporadic.

METHODS

We analyzed vasectomy use in 84 low- and middle-income countries (LMICs) plus the 11 high-income countries with vasectomy prevalence above 1%. These 95 countries comprise 90% of the world's population. Data come from United Nations survey compilations, population estimates, and gender inequality rankings. We also reviewed recent articles on vasectomy and analyses of chronic challenges to vasectomy service provision.

RESULTS

Vasectomy use is 61% lower now than 2 decades ago. Of 922 million women using contraception worldwide, 17 million rely on vasectomy-27 million fewer than in 2001. In contrast, 219 million women use tubectomy-8 million more than in 2001. Of 84 LMICs, 7 report vasectomy prevalence above 2%. In 56 LMICs, no more than 1 in 1,000 women relies on vasectomy. Female-to-male disparities in permanent method use widened globally, from 5:1 to 13:1, and are much higher in some regions and countries (e.g., 76:1 in India). Countries with the highest vasectomy prevalence are among those with the highest gender equality and vice versa.

CONCLUSION

Vasectomy use is surprisingly low globally and declining. Use remains negligible in almost all LMICs, reflecting low demand and program priority. For vasectomy to become an accessible, rights-based option, program efforts need to be holistic, ensuring an enabling environment while coordinating demand- and service-focused efforts. Vasectomy champions at all levels should be supported on a sustained basis. On the demand side, harnessing mass and social media to increase accurate knowledge and normalize vasectomy as a method and service will be particularly valuable. Evidence from Bolivia suggests relatively few trained providers and procedures could result in a country's attaining 1% vasectomy prevalence.

Association Between Publicly Funded Contraceptive Services and the Abortion Rate in Texas, 2010-2015

OBJECTIVE

To evaluate how the availability of contraceptive services was associated with a change in the abortion rate before and after Texas' legislative changes to the family planning budget in 2011 and abortion access in 2013.

METHODS

In this cross-sectional study, we obtained 2010 and 2015 data on contraceptive provision (number of publicly funded clinics and number of contraceptive clients served per 1,000 reproductive-aged women) from the Guttmacher Institute and county-level abortion data from the Texas Department of State Health Services. We categorized counties as having an abortion rate that increased or declined less than the national rate between 2010 and 2015 ( low-decline counties ) compared with those having an abortion rate that declined equal to or greater than the national rate between 2010 and 2015 ( high-decline counties ). We evaluated differences in contraceptive provision between high-decline and low-decline counties and evaluated county characteristics (racial and ethnic composition, unemployment, poverty, uninsured, education, distance to an abortion clinic, deliveries covered by Medicaid, and Catholic hospital marketplace dominance) as potential confounders.

RESULTS

Of 157 counties that had at least one contraceptive clinic in either 2010 or 2015, 49 were low-decline counties and 108 were high-decline counties. Although the total number of publicly funded family planning clinics increased by 10.8%, there was a 4.7% decrease in the total number of contraceptive clients served statewide. Compared with low-decline counties, high-decline counties had a higher median number of contraceptive clients served per 1,000 women aged 18-44 years (31.9 vs 60.7, P <.05) in 2015. Between 2010 and 2015, the abortion rate decreased 19.7% for each 1.0% increase in contraceptive clients served.

CONCLUSION

Texas counties with higher abortion-rate declines had more publicly funded contraceptive clinics and served more contraceptive clients than counties with lower declines, which may indicate the importance of greater access to publicly funded contraceptive services.

Vasectomy Regret Among Childless Men

OBJECTIVE

To address historical concerns surrounding vasectomy in childless men, we sought to evaluate for the level of regret in this unique cohort.

METHODS

The records of patients who underwent vasectomy via single surgeon between 2006 and 2021 were retrospectively reviewed and those who had not fathered children in any capacity at time of vasectomy were selected. We devised a 6-question survey inquiring about regret and thoughts on vasectomy reversal and assisted reproductive technology (ART). The questions are listed in Table 1. Patients were queried via a telephone call to rate their level of regret, both immediately after vasectomy and present day. The cohort was analyzed via age at time of vasectomy, time since vasectomy and marital status.

RESULTS

There were 4812 overall patients who underwent vasectomy in this interval, with 205 (4.3%) who were childless. The response rate was 33.2% (68/205). Average age was 36.6 years with average time since vasectomy at time of phone call was 5.51 years. Regret rate was 4.4% immediately following vasectomy and 7.4% at time of telephone interview. A confirmatory, second consultation before vasectomy was present in 6.8% (14/205). The majority of patients 150/205 (73.1%) were married. When patients were stratified by marital status, there was no significant difference in any of the questions. The majority of patients were satisfied with their decision, with few contemplating or pursuing reversal or ART (Table 1).

CONCLUSION

Regret in childless patients who undergo vasectomy is very rare, with the majority of patients feeling that their life was improved.

The Interest in Permanent Contraception Peaked Following the Leaked Supreme Court Majority Opinion of Roe vs. Wade: A Cross-Sectional Google Trends Analysis

Introduction With the leaked Supreme Court draft regarding Roe vs. Wade, substantial public reactions followed as the horizon of abortion laws within the United States of America have been changing. We sought to compare internet searches for vasectomy and tubal ligation seven days following the leaked draft on May 2, 2022. Methods We used public data provided by Google Trends to investigate the interest and geographic distribution of searches for the two forms of permanent contraception: Vasectomy and tubal ligation. We calculated the mean Search Volume Index (SVI) of these terms. Data analysis was performed with Microsoft Excel Version 16.60 (Redmond, USA), and comparisons between groups were performed using paired t-tests. Results The term 'vasectomy' saw a 121% increase (p=0.0063), and 'tubal ligation' had a 70% (p=0.029) increase compared to the week prior. 49/50 states had increased search inquiries for each term. However, the North and Southwestern regions of the U.S. had increased relative surge for vasectomy and the Midwest region for tubal ligation procedures, respectively. South Dakota and Idaho, with trigger laws that banned abortion immediately following the overturn of Roe vs. Wade, had the greatest surge in SVI for tubal ligation and vasectomy, respectively. Conclusion Our study indicates that with the potential overturn of Roe vs. Wade, there was a significantly increased interest in these two forms of permanent contraception. Future studies should investigate specific concerns and questions patients may have when it comes to the different options of contraception.

Vasectomy Regret or Lack Thereof

Background

Vasectomy is a procedure that results in permanent yet reversible sterility and remains a great contraceptive option for many. Previous research studies have highlighted frequency of vasectomy utilization, defining characteristics of individuals who opt for this method, various surgical techniques, and the risks and benefits associated with the procedure. What remains to be defined is why or why not individuals may experience post-vasectomy regret and whether the previous characteristics correlate.

Objective

The objective of this review is to synthesize information regarding reasons individuals may regret their vasectomy and seek reversal, what options exist for accomplishing the reversal, and patients' fertility prognosis post-vasovasostomy.

Methods

This review utilized a combination of secondary and tertiary data analysis across a wide scope of academic databases pertaining to the topic of interest.

Results

Typically, most males who have sought a vasectomy are satisfied with their decision, however, approximately 6% of this population seeks reversal. Key factors influencing vasectomy regret include age at the time of vasectomy, parental status, pre- and post-operative relationship status, unresolved physical and psychosexual problems, and development of chronic scrotal pain following the procedure. Few options exist for vasectomy reversal including microsurgical reconstructive vasectomy reversal (VR) and sperm extraction for in vitro fertilization. There is no guarantee that fertility will be restored in any case but a major predictive factor for success is the time interval prior to reversal.

Conclusion

Vasectomy is intended to be a permanent form of contraception; however, a minor chance remains that individuals may experience post-operative regret due to various factors. This warrants proper comprehensive counseling by the patient's provider regarding benefits and risks, procedural outcomes, opportunities for reversal, and fertility prognosis.

Vasectomy Knowledge and Interest Among U.S. Men Who Do Not Intend to Have More Children

Vasectomy is used less often than female sterilization, and many men who do not want more children may lack accurate information about vasectomy. Between May and June 2018, we used a nationally representative online panel to survey U.S. men between 25 and 55 years of age who did not want more children about their vasectomy knowledge. We also asked about interest in undergoing the procedure if it were free or low cost and explored whether a paragraph addressing common misperceptions was associated with interest. We assessed characteristics associated with high vasectomy knowledge (≥3 accurate responses to four questions about vasectomy's effect on sexual functioning and method efficacy) and vasectomy interest, using chi-square tests and multivariable-adjusted Poisson regression. Of 620 men surveyed, 564 had complete data on the outcomes and covariates of interest. Overall, 51% of respondents demonstrated high vasectomy knowledge. Men who knew someone who had a vasectomy were more likely to have high knowledge (prevalence ratio [PR]: 1.50; 95% CI [1.22, 1.85]). One-third of the sample (35%) said they would consider getting a vasectomy. Men with high (vs. moderate/low) knowledge were more likely (PR: 1.36; 95% CI [1.04, 1.77]) to consider getting a vasectomy. Race/ethnicity, income level, and receiving the informational paragraph were not associated with vasectomy interest. Greater vasectomy knowledge affects men's interest in the procedure. Given that many U.S. men lack accurate knowledge, efforts are needed to address misinformation and increase awareness about vasectomy to ensure men have the information they need to meet or contribute to reproductive goals.

Vasectomy: is the apparent decline real or not?

Trends in vasectomy use are controversial, but rates might be declining over time. Several factors could contribute to this apparent decrease, which warrant consideration before definitive conclusions are made.
