Abstract

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.
