BACKGROUND: Although human immunodeficiency virus (HIV)-negative men having sex with men (MSM) bear a substantial burden of human papillomavirus (HPV)-associated disease, prospective studies of genital HPV infection in this population are scarce.
METHODS: HPV genotyping was conducted on genital samples from men (aged 18-70 years) from Brazil, Mexico, or the United States who provided specimens at 6-month intervals for up to 4 years. Eligibility criteria included no history of genital warts or HIV infection. Evaluable specimens were collected from 564 MSM and 3029 men having sex with women (MSW). Incidence and clearance estimates with 95% confidence intervals were calculated.
RESULTS: The 12-month cumulative incidence of genital HPV was high in both MSM (25%; 95% confidence interval, 21%-30%) and MSW (21%; 20%-23%). After stratifying by city, MSM and MSW incidence rates were comparable, with 3 exceptions where MSM had higher incidence in ≥1 city: the group of quadrivalent vaccine types, HPV-45, and HPV-11. Median times to HPV-16 clearance were also comparable, with point estimates of >6 months for both MSM and MSW.
CONCLUSIONS: Unlike with many other sexually transmitted infections, genital HPV natural history may be similar in HIV-negative MSM and MSW. Study periods of ≤6 months, however, may not be long enough to accurately measure the persistence of these infections in men.
