Contraceptive sterilization among married adults: national data on who chooses vasectomy and tubal sterilization

BackgroundVasectomy has been found to be a highly cost-effective contraceptive method. For couples, tubal sterilization and vasectomy have the same result, but the two methods are used by different segments of the population.Study designWe conducted an analysis of data from male and female samples of the 2006–2008 National Survey of Family Growth, nationally representative samples of men and women in the United States aged 15–44 years.ResultsAmong married men, 13.1% reported vasectomies (95% confidence interval 10.4%–16.3%), compared to 21.1% (17.8%–24.9%) of married women who reported tubal sterilizations. Men with higher education and income had greater prevalence of vasectomy than those less educated, while women with lower education and income had the highest prevalence of tubal sterilization.ConclusionsEfforts to promote vasectomy use need to understand the reasons behind these differences. Increasing the availability and use of vasectomy will require education about its benefits.
