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.

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