Sustained Rise in Vasectomy Rates After Dobbs v. Jackson: A nationwide analysis using Epic Cosmos

Area of Science:

• Urology
• Public Health
• Reproductive Health

Background:

• The Dobbs v. Jackson Supreme Court decision altered the landscape of reproductive rights in the United States.
• Understanding the impact of this decision on men's reproductive choices is crucial for public health.
• Previous research has not extensively explored changes in male sterilization rates following major legal shifts in reproductive healthcare.

Purpose of the Study:

• To investigate the changes in vasectomy rates in U.S. counties before and after the Dobbs v. Jackson ruling.
• To analyze these changes based on the political leanings of the counties.

Main Methods:

• A cross-sectional study analyzed vasectomy rates among men aged 18-70.
• Data was collected for a 1,041-day period surrounding the Dobbs decision, divided into pre-Dobbs (2017-2019) and post-Dobbs (2022-2025) eras.
• Vasectomy rates were calculated per county as the number of vasectomies per total eligible men in that county.

Main Results:

• The post-Dobbs era saw a higher frequency of younger (<40) and unmarried men undergoing vasectomy.
• Vasectomy rates increased by 22% in Democratic-leaning counties and 7% in Republican-leaning counties after the Dobbs decision.
• These increases were statistically significant, with distinct patterns observed across different political affiliations.

Conclusions:

• Vasectomy rates significantly rose nationwide following the Dobbs decision.
• A notable disparity was observed, with higher vasectomy uptake in Democratic-leaning counties compared to Republican-leaning ones.
• This study is the first to document persistent, politically stratified changes in male reproductive decision-making over three years post-Dobbs.
