Vasectomy: the other (better) form of sterilization

Strategies for obstetricians and gynecologists to advance reproductive autonomy in a post-Roe landscape

The monumental reversal of Roe vs Wade dramatically impacted the landscape of reproductive healthcare access in the United States. The decision most significantly affects communities that historically have been and continue to be marginalized by systemic racism, classism, and ableism within the medical system. To minimize the harm of restrictive policies that have proliferated since the Supreme Court overturned Roe, it is incumbent on obstetrician-gynecologists to modify practice patterns to meet the pressing reproductive health needs of their patients and communities. Change will require cross-discipline advocacy focused on advancing equity and supporting the framework of reproductive justice. Now, more than ever, obstetrician-gynecologists have a critical responsibility to implement new approaches to service delivery and education that will expand access to evidence-based, respectful, and person-centered family planning and early pregnancy care regardless of their practice location or subspecialty.

Explaining sex discrepancies in sterilization rates in the United States: An evidence-informed commentary

CONTEXT

With abortion no longer deemed a constitutional right in the United States (US), the importance of effective contraceptive methods cannot be overstated. Both male sterilization (vasectomy) and female sterilization (tubal ligation) have the lowest failure rates of available means of contraception. Despite the less invasive and reversible nature of vasectomy compared to tubal ligation procedures and even though some healthcare professionals dissuade certain women, especially those who are white and/or economically advantaged, from undergoing a sterilization procedure, female sterilization is approximately three times more prevalent than male sterilization in the US.

PURPOSE

We suggest that the discrepancy in sterilization rates is attributable to the burdens of pregnancy and birth experienced by women, beliefs that pregnancy prevention is a woman's responsibility, a dearth of sex education that results in lack of knowledge and poor understanding of contraception, perceptions of masculinity in which contraception is viewed as feminizing, and the increase in long-term singlehood that shapes the desire of individuals to avoid unwanted pregnancy that may result in single parenting.

IMPLICATIONS

Recent reports suggest that court rulings restricting abortion access and looming threats to contraceptive legality and accessibility may be prompting a national increase in male sterilization.

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.

Qualitative Analysis of Men's Involvement in Family Planning in The Philippines: An Ecological Assessment

While family planning (FP) programs have the capacity to empower women, support gender equality, and reduce poverty, male involvement is an influential factor for the uptake of FP that has been lacking. In the past decade, there have been more progressive FP policies and growing attention on male involvement in FP in the Philippines, providing an opportunity to develop evidence-based interventions to better integrate men into FP services by approaching care delivery from a family-focused perspective. This paper sought to understand the current role of men in FP services and explore how to strengthen facilitators and overcome barriers to optimize men's involvement in FP in the Philippines. Using the Ecological Model for Health Promotion, this qualitative study used convenience sampling to collect data through in-depth interviews and focus group discussions at all levels of the ecosystem. All data were collected in the Albay area, with the exception of some policy data collected in Manila. Qualitative analysis was guided by content analysis. The final sample included 66 participants across the ecosystem. Two primary themes emerged: (1) Resources and health care systems structure impact on male involvement in FP and (2) Education and training that support male involvement in FP. The findings of our qualitative study suggest that while men in the Philippines and their ecosystems support men's FP involvement, the inconsistent health care systems and protocols are not yet reaching men with information and education they need to help them make informed FP decisions with their female partners.

Sedated masculinity: the use of anaesthesia during vasectomy in Israel

Vasectomy is considered a permanent form of contraception for men that can help reduce reproductive inequality. Its underutilisation in the context of the threats it may pose to perceptions of traditional masculinity has been closely investigated, but the lived experience of the procedure itself has been largely overlooked. This paper examines the experience of having a vasectomy in Israel, focusing on the recommended form of anaesthesia. Drawing on 15 semi-structured interviews with Israeli men who have experienced vasectomy, we found that the choice of anaesthesia has a significant impact on the meaning and experience of vasectomy. Unlike the widespread use of local anaesthesia during vasectomy in other countries, vasectomy in Israel is performed almost exclusively under twilight sedation administered intravenously. Based on our findings, we argue that framing vasectomy as an operation that requires sedation is related to views of masculinity and reproduction. Our data suggest that vasectomy in Israel is constituted as a potentially traumatic event, and anaesthesia is employed to protect patients from feelings of embarrassment and discomfort. We conclude that the prevailing method of sedation perpetuates the silencing and marginalisation of vasectomy as a contraceptive method, and consequently, its very limited accessibility in Israel.

Imaginaries of a laparoscope: power, convenience, and sterilization in rural India

Laparoscopic tubal ligation is the most prevalent method of contraception amongst India's rural and urban poor. Drawing on 18 months of ethnographic fieldwork in rural Rajasthan in 2012-2013, this paper investigates how rural women's perceptions of a biomedical instrument-the laparoscope-influence their perceptions of sterilization, a procedure often entrenched in coercive, target- and incentive-driven population control programme. By investigating how a laparoscope is entangled in global exchanges, national policies, institutional arrangements, and local moral worlds, this paper demonstrates that while wider biomedical discourses perpetuate the narrative of safety and convenience, people's everyday lives inform their understandings of technology that is widely known but rarely seen.

A global grounded theory exploration of investigators' perspectives on male hormonal contraceptive development and acceptability

While best practices have been proposed on how to engage men in family planning (FP), the limited options of male hormonal contraceptives (MHC) are a barrier to reaching men as clients of FP programs. The lack of alternative MHC is preventing the global health community from providing holistic reproductive healthcare. A qualitative grounded theory study was conducted in 2020 to explore MHC experts' perceptions around the development and theoretical acceptability of MHCs. Individual in-depth interviews were conducted with 15 key informants. The informants cited evidence that there is a demand for MHC. The inability to access this data by the pharmaceutical industry was acknowledged. Many informants expressed concern of the possibility for MHC to increase male power in a predominantly patriarchal world. To most informants, at least for the initial introduction of MHC, fertility sharing is something that will largely happen among couples alone rather than individually. There is proven demand among women and men for MHC, however industries may still be reluctant to invest. Effort is needed by the sexual and reproductive health and rights community to include male engagement in FP and to advocate for the development and use of MHC as a tool for women's empowerment.

Male or female sterilization - the decision making process: Counselling and regret

OBJECTIVE(S)

To analyze the decision-making process of both male and female sterilization in order to improve counselling and prevent regret after sterilization in the future.

STUDY DESIGN

An online questionnaire regarding sterilization (counselling, sources of information and regret) was promoted on Facebook, Twitter and LinkedIn. A total of 1107 men and women who had undergone or considered sterilization in the Netherlands filled in the questionnaire.

RESULTS

A total of 88.9 % of the sterilized group and 67.4 % in the considered group responded that they felt well informed when they considered sterilization. However, less than half of the participants in both groups knew about all different sterilization methods. In both groups participants reported they consulted their partner the most when they considered sterilization. After sterilization 7.7 % reported having regret. Regret was reported more often when participants were sterilized ≤ 30 years. Most important reasons for regret reported by males were complications, pain, a new wish to conceive and divorce/remarriage. Most important reasons for regret reported by females were pain, complications, a new wish to conceive and menstrual symptoms. A total of 21.1 % in the sterilized and 38.0 % in the considered group responded they would have liked to use a decision aid when they considered sterilization.

CONCLUSIONS

Findings of this study provide insight in the decision-making process regarding sterilization. There is a lack of knowledge of different methods of sterilization and 7.7% regrets their sterilization afterwards. Furthermore, the results show an importance of developing a decision aid for couples considering sterilization.

Assessing Vasectomy-Related Information on YouTube: An Analysis of the Quality, Understandability, and Actionability of Information

This study aims to critically appraise the quality of vasectomy-related health information currently available on YouTube to better address patient information needs moving forward. A YouTube search was performed using the keyword “vasectomy.” The first 100 videos were assessed, with irrelevant and duplicate videos excluded. Two independent reviewers evaluated the remaining videos using the DISCERN instrument for evaluating the quality of information and the Patient Education Materials Assessment Tool for Audiovisual materials (PEMAT-A/V) for assessing the understandability and actionability of materials. Source characteristics and markers of bias and misinformation were also collected. Seventy-eight videos were included in the study, with a mean duration of 6.6 minutes and mean of 216,672 views. The median DISCERN score was poor at 28 (IQR 22–33) out of a possible 80 with mean PEMAT-AV Understandability and Actionability scores of 67.6% (±16.7%) and 33.8% (±36.2%), respectively. A medical doctor was present in 61 (78.2%) of the videos, of which 53 (86.9%) were urologists and 38 (62.2%) promoted their personal practice or institution. False statements regarding vasectomy were made in 14 (17.9%) videos. Notably, no significant difference was noted in quality, understandability, or actionability of videos created by those with personal promotion to those without. The quality of information regarding vasectomy on YouTube is poor and reaches a wide audience. Continued appraisal and creation of YouTube videos that contain quality, understandable and actionable information by urologists is necessary to ensure patients are well-informed.

Vasectomía: conocimientos, percepción y aceptación por parte de estudiantes de medicina en América Latina

Introducción. Los estudiantes de medicina desempeñan un rol importante en el logro de resultados en salud sexual y reproductiva, incluyendo una mayor participación de los hombres en la planificación familiar. Objetivo. Describir el nivel de conocimientos, la percepción y el nivel de aceptación de la vasectomía (i.e. si la recomendarían a sus pacientes y, en el caso de los hombres, si se la realizarían en algún momento de su vida) en una muestra de estudiantes de medicina latinoamericanos. Materiales y métodos. Estudio multicéntrico, transversal analítico realizado en noviembre de 2020 en 2676 estudiantes de medicina (1er-7mo año) de 8 países latinoamericanos. Los datos se recolectaron mediante un cuestionario validado en cada país y diligenciado mediante Google Forms. Se utilizó la prueba de chi-cuadrado de independencia para determinar las diferencias en las variables de estudio (nivel de conocimientos, percepción y nivel de aceptación) para cada subgrupo establecido, con un nivel de significancia de p<0.05. Resultados. El nivel de conocimientos fue alto y medio en 55.38% y 36.32% de los participantes. El país con mayor proporción de estudiantes con alto nivel de conocimientos fue México (77.31%) y el de menor proporción, Brasil (3.33%). Respecto a la percepción, 96.97% de los estudiantes consideró que la vasectomía no afecta la masculinidad y el 98.99% que la anticoncepción también es responsabilidad del hombre. En cuanto a la aceptación, el 94.02% recomendaría el procedimiento, pero solo el 69.82% de los varones (n= 759) se la realizaría. Conclusiones. La mayoría de participantes tiene un buen nivel de conocimientos, buena percepción y un buen nivel de aceptación del procedimiento. No obstante, es necesario implementar más estrategias de capacitación que les permitan promover el uso de la vasectomía como alternativa de planificación familiar en su vida profesional.  

Association between vasectomy and risk of prostate cancer: a meta-analysis

BACKGROUND

The debate over the association between vasectomy and prostate cancer has been lasted about 40 years and there is no sign of stopping. In the present study, we aimed to evaluate whether vasectomy is associated with prostate cancer based on the most comprehensive and up-to-date evidence available.

METHODS

The PubMed, Cochrane Library, and EMBASE databases were systematically searched inception to March 14, 2021 without year or language restriction. Multivariable adjusted risk ratios (RRs) were used to assess each endpoint. Risk of bias was assessed using the Newcastle-Ottawa scale.

RESULTS

A total of 58 studies involving 16,989,237 participants fulfilled inclusion criteria. There was significant association of vasectomy with risk of any prostate cancer (risk ratio, 1.18, 95% CI, 1.07-1.31). Association between vasectomy and advanced prostate cancer (risk ratio, 1.06, 95% CI, 1.01-1.12), low-grade prostate cancer (risk ratio, 1.06, 95% CI, 1.02-1.10), and intermediate-grade prostate cancer (risk ratio, 1.12, 95% CI, 1.03-1.22) were significant. There was no significant association between vasectomy and prostate cancer-specific mortality (risk ratio, 1.01, 95% CI, 0.93-1.10).

CONCLUSIONS

This study found that vasectomy was associated with the risk of any prostate cancer and advanced prostate cancer. From the current evidence, patients should be fully informed of the risk of prostate cancer before vasectomy.

Men's Vasectomy Knowledge, Attitudes, and Information-Seeking Behaviors in the Southern United States: Results From an Exploratory Survey

Vasectomy is one of the few options men have to manage their reproductive capacity and take on a more equitable role in pregnancy prevention. While the method is underused throughout the United States, the southern states have a lower prevalence rate compared to the rest of the country. Existing survey research does not assess what men know or think about the procedure as a means of understanding why this is the case. We created and conducted an exploratory survey to assess men’s knowledge, attitudes, and information-seeking behaviors about vasectomy in the Southern United States. We used targeted Facebook advertising to recruit men ages 25–70 years living in 7 southern states to complete an online survey (n = 397). Using regression analyses, we identify that participants who had a vasectomy knew more about the procedure than participants who had not. Participants who had not had a vasectomy had less positive attitudes about the procedure across all six attitude subscales compared to participants with vasectomies. We highlight potential avenues for future research to understand why this may be the case. Finally, the majority of participants knew someone who had had a vasectomy. This suggests that men disclose having a vasectomy to others. The interpersonal dynamics around vasectomy decision-making and disclosure remain unknown and a viable area for future research. Findings from this exploratory survey may be used by public health officials interested in implementing campaigns to increase knowledge about vasectomy and reduce stigma, which may encourage more positive attitudes about the procedure.

A qualitative exploration of men's perceptions of the terms "male sterilization" versus "vasectomy" in the southern United States

OBJECTIVES

Clinical literature and contraception information guides use the terms "male sterilization" and "vasectomy" interchangeably. We investigate the meanings men attach to "sterilization" and how those meanings compare to perceptions of "vasectomy."

STUDY DESIGN

Cisgender, heterosexual men, ages 25 to 67, living across seven U.S. southern states participated in individual telephone interviews from May to December 2019. Interviews explored men's experiences with contraception, including their perception of the term "sterilization." We audio-recorded and transcribed the interviews and conducted thematic analyses using an inductive approach.

RESULTS

While most participants described "vasectomy" as a relatively benign procedure, they described "sterilization" as "sinister," "bleak," and "barbaric." Participants' discussions of sterilization invoked associations with eugenicist practices and specific historical examples of forced sterilization. While some participants recognized that vasectomy is a means of achieving sterilization, most viewed the term "sterilization" as incongruous with the modern medical procedure of "vasectomy," precisely because sterilization has been used as a form of reproductive oppression.

CONCLUSION

Our findings suggest that men have strong affective responses to the term "sterilization." Participants' knowledge of historical eugenicist practices has implications for the acceptability of vasectomy as a permanent contraceptive option in our contemporary context.

IMPLICATIONS

The phrase "male sterilization" can be associated with eugenics and coercive reproductive practices. Using the term for reproductive counselling, education, or research purposes may have implications for the acceptability of vasectomy as a permanent contraceptive option.

Married couples' dynamics, gender attitudes and contraception use in Savannakhet Province, Lao PDR

Background

The use of contraception in Lao PDR remains inadequate. In 2017, unmet contraception needs among married women aged 15–49 were 14.3% in Lao PDR overall and 18.6% in the province of Savannakhet. Although the government has a goal to reduce gender inequalities, they still persist in many areas.

Objective

The aim of this research was to understand the extent to which couples’ dynamics and gender attitudes affect contraception use in Savannakhet, Lao PDR.

Methods

To conduct this research, mixed methods were used. Quantitative methods took the form of a survey filled out by 200 married couples in the province of Savannakhet. Afterwards, focus group discussions were carried out to give meaning to the quantitative data and to obtain a deeper understanding of gender roles and contraceptive use.

Results

Findings showed that most couples rely on female-dependent contraceptives and that while women hold most of the family planning responsibility, men’s opinions have more weight on the final decision. Additionally, women’s financial autonomy and spousal communication regarding birth control were associated with contraceptive use within the couple. However, this communication usually began after the birth of the third child. Lastly, the hypothesis that egalitarian gender attitudes were associated with contraceptive use could not be confirmed.

Conclusion

This study clearly demonstrates that contraception use is influenced by couples’ dynamics, more specifically spousal communication, in Lao PDR. The findings have highlighted the need to involve men in all stages of family planning, and to foster both spousal communication and financial autonomy for women. If the findings are implemented, this may foster shared decision making within couples.

Male partners and medical staff's perception on contributing factors of Family Planning (FP) in Fiji

Introduction

Male partners play an important role in Family Planning (FP) as they are directly involved in the decision making of FP with their partners. Medical staff are also involved with FP services that have a direct relation to usage of FP among the men and women. This study is aimed to explore the perception of male partners and the medical staff about factors affecting FP decision in Fiji.

Materials and methods

The qualitative study was carried out among men who were partners of the pregnant women, and medical staff at Ba Mission Hospital (BMH), Fiji in 2019. The study utilised semi-structured questionnaire to guide four Focus Group Discussions (FGDs) among 10 male partners and 10 medical staff. Interview was audio transcribed and analyzed using thematic analysis.

Result

The common themes identified from the male interviews were the opposition of male partners, religious norms and cultural beliefs, accessibility of contraception, and previous FP failure. The common themes identified from the medical staff interviews were; effectiveness of counseling, concerns on men involvement in FP, and barriers towards FP.

Conclusion

This study reveals the need for better counseling, more awareness on FP for men and more involvement of men by the medical staff in FP practices.

Religious beliefs, social pressure, and stigma: Rural women's perceptions and beliefs about vasectomy in Pwani, Tanzania

Despite being a reliable and cost effective family planning method, vasectomy remains underutilized in many low resource settings such as East Africa. We explored rural women’s perceptions and beliefs regarding barriers to vasectomy use in the low resource setting of Pwani, Tanzania. The qualitative study used in-depth semi-structured interviews to obtain data. Purposive sampling was used to recruit 20 married/cohabiting women with two or more children. Thematic analysis guided the data analysis, with qualitative data reporting informed by COREQ guidelines. Most participants were Muslim and had between two and six children. Most had completed primary-level education and were engaged in small-scale farming. We extracted three main themes with associated sub-themes:1) lack of education, which included men’s education levels and inadequate knowledge and misinformation 2) religious beliefs, social pressure and stigma, which included community stigma and the belief that vasectomy was not good for men with multiple wives; and 3) promoting men’s involvement in family planning which included educating men and the women’s perceived role in promoting vasectomy. Participating women perceived vasectomy uptake to be affected by a lack of low knowledge (among men, women, and the community), misinformation, and various sociocultural barriers. Efforts to promote vasectomy and male involvement in reproductive health services should be directed to addressing deeply-rooted sociocultural barriers. Women may have an essential role in encouraging their partners’ vasectomy uptake. In addition, engaging couples in family planning education is critical to enhance knowledge. Ideally, such community based education should be conducted in partnership with communities and healthcare providers.

RISUG® as a male contraceptive: journey from bench to bedside

Even after decades of research men still lack reliable and reversible contraceptive methods comparable to female methods of contraception. Traditional methods of male contraception present a high failure rate and also involve high risk both when used for contraception and for protection against sexually transmitted diseases. Various chemical, hormonal, immunological, vas based and herbal methods of contraception have been examined by scientists world over during the past four decades. Among the possible lead approaches, exogenous hormonal contraception, either alone or in combination with progesterone or antiandrogen, is being viewed at low profile because of their insufficiency in inducing uniform suppression of spermatogenesis and steroid related long term complications. As an alternative to vasectomy, among various intravasal devices being examined, RISUG® (Reversible Inhibition of Sperm Under Guidance), a co-polymer of styrene and maleic anhydride offers long term contraception with safety, efficacy and it can be delivered by no-scalpel injection. Thus it is the only male contraceptive procedure currently under Phase- III Clinical Trial. The non-invasive reversal technique, successfully demonstrated in langur monkeys and functional reversal achieved with dimethyl sulphoxide (DMSO) and sodium bicarbonate (NaHCO3) in rats and rabbits with safety at F1 generation (first filial generation) have projected RISUG® as a better alternative to vasectomy. In this narrative review we revisit the long journey of RISUG® beginning with formulation on a bench towards reaching the market as a safe and effective contraceptive method, discussing various milestones and roadblocks of this expedition awaiting the mandatory regulatory clearance from the Government of India. Successful completion of ongoing phase III clinical trials with demonstration of reversal in human volunteers will give an indigenously developed male contraceptive to the world.

Comparative study between the excision-ligation and autoligation of vas deferens technique for teaser rams preparation

AIM

The present study was designed to demonstrate the autoligation (AL) of vas deferens and the excision-ligation (EL) technique to generate vasectomized rams to reduce the complications, operative time, and price of the vasectomy techniques.

MATERIALS AND METHODS

A total of 12 healthy and mature Iraqi Awassi rams were used, which divided into two groups, six rams for each one. The former group was performed the EL technique while the latter group, the AL of vas deferens technique was used.

RESULTS

The results of the present study found that both techniques were same with the reproductive efficient examinations that mean the two techniques had same ability to close the male genital passage for teaser rams preparation. However, the methods were different with the histopathological changes, operation time, prices, and complications, which were minor in the AL of vas deferens compared with the EL technique.

CONCLUSION

The AL technique of vas deferens to prepare teaser animal is recommended over the EL technique due to different aspects such as cost, fewer complications, and active teaser for a long period are the main aspects of AL technique.

More Than a Physical Burden: Women's Mental and Emotional Work in Preventing Pregnancy

In the United States, responsibility for preventing pregnancy in heterosexual relationships disproportionately falls on women. While the biotechnological landscape of available methods may explain the assignment of the physical burden for contraception to women, this does not mean the concomitant time, attention, and stress that preventing pregnancy requires must also be primarily assumed by women. Building on work identifying health care providers as contributors to the construction of normative ideas about reproduction, this study analyzed 52 contraceptive counseling visits with women who reported they did not want future children for the construction of responsibility for the mental and emotional aspects of contraception. Offering a case of how gender inequality is (re)produced through clinical encounters, findings demonstrate that clinicians discursively constructed these responsibilities as women's and point to structural aspects of the visit itself that reify this unequal burden as normal. Results are consistent with research identifying the broader feminization of family health work in heterosexual relationships. To the extent that the distribution of the mental and emotional responsibilities of preventing pregnancy is both a product of and contributor to gender inequality, this analysis yields insight into the production-and possible deconstruction-of (reproductive) health care as a gendered social structure.

Married Men and Vasectomy: A Focused Group Study in an Urban Community in Ghana

An effective method of birth control in men yet least accepted and patronized is vasectomy. Vasectomy provides health benefits to the user, his direct family, and the entire population as it helps to control population growth. This article explored the beliefs and attitudes of commercial drivers on vasectomy in an urban community in Ghana. The study employed qualitative exploratory design using focus group discussion. Data were collected from 12 married men between the ages of 45 to 60 years who were selected through purposive sampling method. The focus group discussions were audiotaped, handwritten, and recorded. Recorded data were then transcribed verbatim, and the current version of the NVivo software for analyzing qualitative data was used to manage the data. Three major themes emerged from the study: knowledge of respondents on vasectomy, beliefs, and attitudes of married men toward vasectomy. Each of the themes had three subthemes. The study revealed that vasectomy was perceived by some of the respondents to be synonymous to castration which comes with negative effects. Inadequate knowledge, negative perceptions, future uncertainty, and the irreversible nature of vasectomy emerged as contributing to the low patronage and some of the reasons why most of the respondents had no intentions of opting for vasectomy. In view of these findings, it is imperative for all stakeholders to give urgent attention to behavior change strategies that can be put in action to ameliorate the effects of these negative attitudes and misbeliefs. Ultimately, the tide can be turned around and vasectomy will be a preferred alternative when it comes to family planning in Ghana.

Surgical sterilization among US men and women with employer-based insurance: A claims data analysis

OBJECTIVE

To assess variability in the use of surgical sterilization among privately insured U.S. men and women.

STUDY DESIGN

We queried the MarketScan Commercial Claims database using CPT, ICD9, and HCPCS codes to identify 658,509 individuals between 18-65 years old (0.37% of total) who underwent male or female sterilization between 2009-2014. We examined annual trends using Cochran-Mantel-Haenszel test. We analyzed differences in age, geographic distribution, and family size using Wilcoxon sum-rank and generalized chi-squared tests.

RESULTS

Between 2009-2014, 422,290 men (0.55% of total men) and 236,219 women (0.24% of total women) with employer-sponsored insurance underwent male and female sterilization, respectively. Annual male sterilizations decreased from 77,565 (0.60%) in 2009 to 61,436 (0.51%) in 2014 (p<.001), while annual female sterilizations decreased from 43,766 (0.26%) to 30,465 (0.19%) (p<.001) over the same time period. Median age at time of male or female sterilization was 38 and 37 years, respectively. The decision to undergo sterilization at age 35 or older was associated with family size of 4 or more individuals (p<.001). Sterilization was more common in urban areas, with 84% of male sterilizations and 79% of female sterilizations performed in urban areas. 79% of men compared to 60% of women who underwent sterilization were the primary policyholders of their employer-sponsored healthcare plans (p<.001).

CONCLUSION

Male sterilization was twice as common as female sterilization in this privately insured cohort. Use of surgical sterilization was associated with increased age and larger family size. There was a decline in the annual number of male and female sterilizations during the study period.

IMPLICATIONS

Male sterilization is more common among US men with employer-based insurance than among the general population. The decline in sterilization may reflect cultural factors and the rise of long-acting reversible contraception. Analyzing the sociodemographic factors impacting sterilization may provide insight into contraceptive choice and improve reproductive health services.

Exploring access to vasectomy services: a case study of funding in Counties Manukau

INTRODUCTION Although vasectomy rates in New Zealand have been reported as among the highest worldwide, there is limited information about who is receiving these services and how they are being accessed. This information is needed to develop equitable access to vasectomy services. AIM To describe the ethnicity and socioeconomic status of men accessing District Health Board-funded and self-funded vasectomies in Counties Manukau. METHODS A retrospective cohort analysis of provider data linked to ethnicity and area deprivation as an indicator of socioeconomic status. RESULTS Of 332 vasectomies, 66% were for New Zealand European men. Socioeconomic status was not associated with the number of procedures for New Zealand European men, but of the Māori and Pacific men who underwent vasectomies, most lived in the greatest areas of deprivation; 58% (18/31) and 50% (12/24), respectively. When vasectomies were funded, the number of procedures doubled for men from areas of high deprivation. The number of procedures was low for men of other ethnicities. DISCUSSION Our findings indicate differential access to vasectomies by ethnicity and socioeconomic status. Funding vasectomies may provide community benefits in terms of improving equity in access and alleviating a financial burden for many families living in areas of high deprivation.

Talking about male body-based contraceptives: The counseling visit and the feminization of contraception

In developed countries, women bear the primary, and sometimes exclusive, responsibility for preventing pregnancy in heterosexual sexual relations. This unequal burden is not an intrinsic fact; it is the consequence of broad social narratives and interpersonal negotiations. The contraceptive counseling visit is increasingly recognized as a site of the discursive production of normative ideas about reproduction, suggesting that clinicians themselves may contribute to the assignment of responsibility for contraceptive labor to women (i.e. the feminization of contraception). Scholars have not yet considered how providers talk to patients about methods that are male body-based (i.e. condoms, withdrawal, and vasectomy) and, as such, may disrupt the feminization of responsibility for contraception. Using transcripts of 101 contraceptive counseling visits recorded between 2009 and 2012 in the San Francisco Bay Area, I investigate how clinicians discuss male body-based methods with female patients. Drawing on a constructivist approach, I find that clinicians generally devalued male body-based methods in their counseling. They did so by, first, failing to discuss them as options for long-term contraception. Second, when they did discuss them, clinicians tended to emphasize aspects of the methods that were presumed "negative" (e.g. the lower efficacy of withdrawal and condoms) but not features that patients might view positively (e.g. the high efficacy of vasectomy or the lack of side effects with condoms and withdrawal). In aggregate, these discursive practices marginalize male body-based methods as contraceptive choices. As a practical effect, this may encourage women to choose a method that does not best meet their preferences. At a structural level, by devaluing methods that could undercut the unequal division of fertility work, these discursive patterns contribute to the feminization of responsibility for contraception and the retrenchment of the unequal gendered division of fertility work.

Contraceptive method use in the United States: trends and characteristics between 2008, 2012 and 2014

Objective

The objective was to examine levels of, correlates of and changes in the use of individual and grouped methods of contraception among US females aged 15–44 from 2008 to 2014.

Study design

Using three rounds of the National Survey of Family Growth, we analyzed samples of 12,279 (2008), 5601 (2012) and 5699 (2014) females. We conducted simple and multivariable logistic regression analyses to identify associations between demographic characteristics and contraceptive use, as well as between characteristics and changes in use patterns.

Results

In terms of overall trends in contraceptive use between 2008 and 2014, there was no significant change in the proportion of women who used a method among either all women (60%) or those at risk of unintended pregnancy (90%). Significant changes in use occurred among six methods. The largest increase in use was among users of long-acting reversible contraceptive (LARC) methods, including the intrauterine device and implant — from 6% to 14% — across almost all population groups of female contraceptive users, while the largest decrease occurred among users of sterilization — from 37% to 28% — with lower-income women driving the decline in female sterilization and higher-income women driving the decline in a partner’s sterilization as a primary method. Moderate increases were seen in the use of withdrawal and natural family planning.

Conclusion

Most shifts in recent contraceptive use have occurred among the most effective methods — sterilization and LARCs. Differences in method-specific user characteristics underscore the importance of ensuring full access to the broad range of methods available.

Implications

The lack of change in the overall use of contraceptives among women at risk for unintended pregnancy may have implications for the extent to which further declines in national rates of unintended pregnancy can be expected.

HIGH PREVALENCE OF VOLUNTARY STERILIZATION AMONG AMERICAN WOMEN EXPLAINED BY TRADE-OFFS RESULTING FROM MALE PARENTAL COMMITMENT

Tubal ligation is the modal form of family planning among American women aged 30 and older. As the preference for tubal ligation over cheaper, lower risk and more reliable methods, such as vasectomy, has puzzled experts, a theoretical approach that explains this preference would be useful. The present study investigates the high prevalence of voluntary sterilization among American women from the perspective of life history theory, arguing that the trade-offs between investing in current and future offspring will favour tubal ligation when women cannot obtain reliable male commitment to future parental investment. Data came from the National Survey of Fertility Barriers (NSFB), a nationally representative survey of 4712 American women aged 25-45 conducted between 2004 and 2007. Four novel predictions of the prevalence of tubal ligation, drawn from life history theory, were developed and tested: 1) it is most common among unpartnered women with children, and least common among married women with children; 2) it is negatively correlated with age at first birth; 3) it is least common among highly educated women without children, and most common among less educated women with children; and 4) among women with two or more children, it is positively correlated with lifetime number of long-term partners. These predictions were tested using multivariate regression analysis. The first prediction was not supported: women with children were more likely to be sterilized, regardless of their marital status. The other three predictions were all supported by the data. The results suggest that trade-offs influence women's decisions to undergo voluntary sterilization. Women are most likely to opt for tubal ligation when the costs of an additional child will impinge on their ability to invest in existing offspring, especially in the context of reduced male commitment.

The Association Between Vasectomy and Prostate Cancer: A Systematic Review and Meta-analysis

Importance

Despite 3 decades of study, there remains ongoing debate regarding whether vasectomy is associated with prostate cancer.

Objective

To determine if vasectomy is associated with prostate cancer.

Data Sources

The MEDLINE, EMBASE, Web of Science, and Scopus databases were searched for studies indexed from database inception to March 21, 2017, without language restriction.

Study Selection

Cohort, case-control, and cross-sectional studies reporting relative effect estimates for the association between vasectomy and prostate cancer were included.

Data Extraction and Synthesis

Two investigators performed study selection independently. Data were pooled separately by study design type using random-effects models. The Newcastle-Ottawa Scale was used to assess risk of bias.

Main Outcomes and Measures

The primary outcome was any diagnosis of prostate cancer. Secondary outcomes were high-grade, advanced, and fatal prostate cancer.

Results

Fifty-three studies (16 cohort studies including 2 563 519 participants, 33 case-control studies including 44 536 participants, and 4 cross-sectional studies including 12 098 221 participants) were included. Of these, 7 cohort studies (44%), 26 case-control studies (79%), and all 4 cross-sectional studies were deemed to have a moderate to high risk of bias. Among studies deemed to have a low risk of bias, a weak association was found among cohort studies (7 studies; adjusted rate ratio, 1.05; 95% CI, 1.02-1.09; P < .001; I2 = 9%) and a similar but nonsignificant association was found among case-control studies (6 studies; adjusted odds ratio, 1.06; 95% CI, 0.88-1.29; P = .54; I2 = 37%). Effect estimates were further from the null when studies with a moderate to high risk of bias were included. Associations between vasectomy and high-grade prostate cancer (6 studies; adjusted rate ratio, 1.03; 95% CI, 0.89-1.21; P = .67; I2 = 55%), advanced prostate cancer (6 studies; adjusted rate ratio, 1.08; 95% CI, 0.98-1.20; P = .11; I2 = 18%), and fatal prostate cancer (5 studies; adjusted rate ratio, 1.02; 95% CI, 0.92-1.14; P = .68; I2 = 26%) were not significant (all cohort studies). Based on these data, a 0.6% (95% CI, 0.3%-1.2%) absolute increase in lifetime risk of prostate cancer associated with vasectomy and a population-attributable fraction of 0.5% (95% CI, 0.2%-0.9%) were calculated.

Conclusions and Relevance

This review found no association between vasectomy and high-grade, advanced-stage, or fatal prostate cancer. There was a weak association between vasectomy and any prostate cancer that was closer to the null with increasingly robust study design. This association is unlikely to be causal and should not preclude the use of vasectomy as a long-term contraceptive option.

Power and the gendered division of contraceptive use in Western European couples

Recent research has approached contraceptive use, or "fertility work", as another household task that is primarily managed by women. Building on the theoretical frameworks of relative resource theory and gender perspectives, this study investigates the association between partners' power (measured as their relative education, division of housework and decision-making) and the choice of male versus female, or no contraception. Data from the Generations and Gender Survey for four Western European countries (Austria, Belgium, France and Germany; 2005-2010) are used to examine the hypotheses with multinomial logistic diagonal reference models. The results show that man's and woman's educational level are equally important predictors for a couple's contraceptive method choice. Furthermore, the findings suggest that households in which the man performs more housework or the woman has more say in decisions are more likely to rely on male methods or female sterilization, rather than on the more commonly used female reversible methods.

Barriers to Offering Vasectomy at Publicly Funded Family Planning Organizations in Texas

Few publicly funded family planning clinics in the United States offer vasectomy, but little is known about the reasons this method is not more widely available at these sources of care. Between February 2012 and February 2015, three waves of in-depth interviews were conducted with program administrators at 54 family planning organizations in Texas. Participants described their organization’s vasectomy service model and factors that influenced how frequently vasectomy was provided. Interview transcripts were coded and analyzed using a theme-based approach. Service models and barriers to providing vasectomy were compared by organization type (e.g., women’s health center, public health clinic) and receipt of Title X funding. Two thirds of organizations did not offer vasectomy on-site or pay for referrals with family planning funding; nine organizations frequently provided vasectomy. Organizations did not widely offer vasectomy because they could not find providers that would accept the low reimbursement for the procedure or because they lacked funding for men’s reproductive health care. Respondents often did not perceive men’s reproductive health care as a service priority and commented that men, especially Latinos, had limited interest in vasectomy. Although organizations of all types reported barriers, women’s health centers and Title X-funded organizations more frequently offered vasectomy by conducting tailored outreach to men and vasectomy providers. A combination of factors operating at the health systems and provider level influence the availability of vasectomy at publicly funded family planning organizations in Texas. Multilevel approaches that address key barriers to vasectomy provision would help organizations offer comprehensive contraceptive services.

Vasectomy and risk of prostate cancer: population based matched cohort study

OBJECTIVE

 To determine the association between vasectomy and prostate cancer, adjusting for measures of health seeking behaviour.

DESIGN

 Population based matched cohort study.

SETTING

 Multiple validated healthcare databases in Ontario, Canada, 1994-2012.

PARTICIPANTS

 326 607 men aged 20 to 65 who had undergone vasectomy were identified through physician billing codes and matched 1:1 on age (within two years), year of cohort entry, comorbidity score, and geographical region to men who did not undergo a vasectomy.

MAIN OUTCOMES MEASURES

 The primary outcome was incident prostate cancer. Secondary outcomes were prostate cancer related grade, stage, and mortality.

RESULTS

 3462 incident cases of prostate cancer were identified after a median follow-up of 10.9 years: 1843 (53.2%) in the vasectomy group and 1619 (46.8%) in the non-vasectomy group. In unadjusted analysis, vasectomy was associated with a slightly increased risk of incident prostate cancer (hazard ratio 1.13, 95% confidence interval 1.05 to 1.20). After adjustment for measures of health seeking behaviour, however, no association remained (adjusted hazard ratio 1.02, 95% confidence interval 0.95 to 1.09). Moreover, no association was found between vasectomy and high grade prostate cancer (adjusted odds ratio 1.05, 95% confidence interval 0.67 to 1.66), advanced stage prostate cancer (adjusted odds ratio 1.04, 0.81 to 1.34), or mortality (adjusted hazard ratio 1.06, 0.60 to 1.85).

CONCLUSION

 The findings do not support an independent association between vasectomy and prostate cancer.

Mexican Men's View of Vasectomy

The present study explored the views of Mexican men concerning vasectomy. One hundred and five men who had not had a vasectomy were asked to complete the following phrase "If you no longer wanted to have more children and a vasectomy was suggested, you would react with . . . or you would think . . . " with at least five different answers. Participants then had to rank each of their answers according to how well they describe the participant's feelings in the hypothetical situation. The results were analyzed using the Natural Semantic Networks Technique. The most common words used by participants with a limited educational background were reject, followed by fear and anger, and they did not use any words that implied acceptance of vasectomy. In contrast, the most common words used by participants with higher education were curiosity, followed by acceptance and interest; however, they also used the words fear and insecurity. The most frequent attitudes reported by men with limited education were negative, whereas participants with a higher education reported more ambivalent attitudes. These findings are discussed in light of sociocultural features and could be helpful in designing reproductive health programs with more effective counseling to diminish negative views about vasectomy.

The perplexing links between contraceptive sterilization and (dis)advantage in ten low-fertility countries

This study investigated the association between contraceptive sterilization and socio-economic status (measured by educational attainment) in ten countries, using data from the 2006-10 National Survey of Family Growth and the 2004-10 Generations and Gender Surveys. The findings confirm that a long-standing association between socio-economic status and sterilization persists in the contemporary United States: female sterilization is associated with economic disadvantage, whereas male sterilization is associated with economic advantage. The latter association is found to be unique to the United States, but female sterilization is associated with disadvantage in most of the other countries studied. While basic demographic background factors such as early childbearing and parity can explain the observed associations in most of the countries, a strong gendered association between sterilization and socio-economic status remains in the United States and Belgium even after adjusting for these factors.

Perceived Interest in Vasectomy among Latina Women and their Partners in a Community with Limited Access to Female Sterilization

The low prevalence of vasectomy among Latino men in the United States is often attributed to cultural characteristics despite limited evidence supporting this hypothesis. We assessed male partners' perceived willingness to undergo vasectomy through surveys with 470 Mexican-origin women who did not want more children in El Paso, Texas. Overall, 32% of women reported that their partner would be interested in getting a vasectomy. In multivariable analysis, completing high school (OR=2.03 [1.05, 3.95]), having some college education (OR=2.97 [1.36, 6.48]) or receiving US government assistance (OR=1.95 [1.1, 3.45]) was associated with partners' perceived interest. Additionally, we conducted two focus groups on men's knowledge and attitudes about vasectomy with partners of a subsample of these women. Despite some misperceptions, male partners were willing to get a vasectomy, but were concerned about cost and taking time off work to recover. Health education and affordable vasectomy services could increase vasectomy use among Mexican-origin men.

Permanent contraception for women

Permanent methods of contraception are used by an estimated 220 million couples worldwide, and are often selected due to convenience, ease of use and lack of side effects. A variety of tubal occlusion techniques are available for female permanent contraception, and procedures can be performed using a transcervical or transabdominal approach. This article reviews currently available techniques for female permanent contraception and discusses considerations when helping patients choose a contraceptive method and tubal occlusion technique.

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.

Postpartum contraception

As birth spacing has demonstrated health benefits for a woman and her children, contraception after childbirth is recognized as an important health issue. The potential risk of pregnancy soon after delivery underscores the importance of initiating postpartum contraception in a timely manner. The contraceptive method initiated in the postpartum period depends upon a number of factors including medical history, anatomic and hormonal factors, patient preference, and whether or not the woman is breastfeeding. When electing a contraceptive method, informed choice is paramount. The availability of long-acting reversible contraceptive methods immediately postpartum provides a strategy to achieve reductions in unintended pregnancy.

Marital status and female and male contraceptive sterilization in the United States

OBJECTIVE

To examine female and male sterilization patterns in the United States based on marital status, and to determine if sociodemographic characteristics explain these patterns.

DESIGN

Survival analysis of cross-sectional data from the female and male samples from the 2006-2010 National Survey of Family Growth.

SETTING

Not applicable.

PATIENT(S)

The survey is designed to be representative of the US civilian noninstitutionalized population, ages 15-44 years.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Vasectomy and tubal sterilization.

RESULT(S)

In the United States, vasectomy is the near-exclusive domain of married men. Never-married and ever-married single men, and never-married cohabiting men, had a low relative risk (RR) of vasectomy (RR = 0.1, 0.3, and 0.0, respectively), compared with men in first marriages. Tubal sterilization was not limited to currently married, or even to ever-married women, although it was less common among never-married single women (RR = 0.2) and more common among women in higher-order marriages (RR = 1.8), compared with women in first marriages. In contrast to vasectomy, differential use of tubal sterilization by marital status was driven in large part by differences in parity.

CONCLUSION(S)

This study shows that being unmarried at the time of sterilization--an important risk factor for poststerilization regret--was much more common among women than men. In addition to contributing to the predominance of female, vs. male, sterilization, this pattern highlights the importance of educating women on the permanency of sterilization, and the opportunity to increase reliance on long-acting reversible contraceptive methods.
