Abstract
Postcoital genital washing by uncircumcised men may affect the risk
of male HIV acquisition.
Method: We assessed the association between self-reported washing after sex in
2976 initially HIV-negative, uncircumcised men enrolled in a prospective cohort study
in Rakai, Uganda.
Results: Data from the 2976 participants who reported sexual intercourse in the past
12 months contributed 4290 visits, with 7316.6 person-years of observation during
the 2-year follow-up. The overall HIV-incidence was 1.28/100 person-years 95%CI
(1.04–1.57). About 91.0% of men reported washing their penis after sex, and their HIV
incidence was 1.34/100 person-years (95%CI 1.08–1.66), compared with an incidence
of 0.62/100 person-years (95%CI 0.17–1.60) in men who did not wash their penis after
intercourse. Using Poisson multivariable regression, the adjusted incidence rate ratio
of HIV acquisition associated with postcoital washing was 1.94 (95%CI 0.71–5.29).
Conclusion: Postcoital penile washing, as practiced in this rural African population
does not afford protection from HIV acquisition among uncircumcised men, and may
increase risk.
