| Sumario: | Objectives. To examine how men's characteristics and traditional masculine attitudes are associated with vasectomy utilization in the United States. Methods. Using 2022–2023 National Survey of Family Growth data on men aged 30 to 49 years (n = 2278), we conducted descriptive statistics and multivariable logistic regression to assess how sociodemographic characteristics and traditional masculine attitudes are associated with undergoing vasectomy. Results. Approximately 1 in 9 men (11.9%) reported undergoing vasectomy. Men who agreed that men have greater sexual needs than women were more likely to report having ever had a vasectomy (adjusted odds ratio = 1.86; 95% confidence interval = 1.24, 2.80). Other masculine attitudes were not significantly associated with vasectomy utilization. Conclusions. Gender beliefs are an important and overlooked component of male contraceptive behavior. Men may view vasectomies as a means to maintain sexual continuity by reducing reliance on female-controlled contraception, suggesting opportunities to reframe vasectomy utilization within public health messaging.
