Contraception is used to help prevent unintended pregnancies and sexually transmitted infections (STI). Higher percentages of pregnancies to unmarried persons are unintended than for those who are married (1). Patterns of contraceptive use as reported by women, including differences by marital status, are well documented using National Survey of Family Growth (NSFG) data (2–4); however, less research focuses on contraceptive use as reported by men. Using 2011–2015 NSFG data from men, with selected time trends, this data brief describes contraceptive use at last recent vaginal sexual intercourse (within 3 months) among unmarried men, focusing primarily on male methods of contraception (condom, withdrawal, and vasectomy).
