Current guidelines recommend that sexually active men who have sex with men (MSM) be screened at least annually for bacterial sexually transmitted infections (STIs) at sites of sexual contact regardless of condom use. Extragenital (rectal and pharyngeal) STI are common in MSM and associated with an increased risk of human immunodeficiency virus. We describe the prevalence of MSM who reported any STI test and an extragenital STI test in the past 12 months (p12m) in the United States.


Data were obtained from the 2017 American Men's Internet Survey, an annual cross-sectional behavioral internet survey of MSM in the United States. We examined the prevalence of MSM who reported any STI test and an extragenital STI test in the p12m and compared the prevalence across demographic, clinical, and behavioral factors.


Of 10,049 sexually active MSM who participated in American Men's Internet Survey 2017, 42% reported any STI test in the p12m and 16% reported an extragenital (rectal or pharyngeal) STI test in the p12m. Among those who reported getting an extragenital STI test in the p12m, 19% reported providing a throat swab only, 14% reported providing a rectal swab only, and 68% reported providing both a rectal and throat swab for STI testing.


In a large sample of internet-using MSM in the United States, levels of STI screening were suboptimal, with fewer than half (42%) of MSM reporting any STI test and even fewer reporting an extragenital STI test in the p12m. Increased efforts are needed to ensure annual STI screening guidelines among MSM are implemented.
