The San Francisco Men's Health Study prospectively followed 1,034 single men aged 25–54, recruited via multistage probability sampling, to investigate the epidemiology and natural history of AIDS. At baseline, 48.5% of homosexual/bisexual participants were HIV seropositive, with rates ranging from 17.6% among those reporting no male partners to 70.8% among those with more than 50 partners, and only receptive anal/genital contact and douching were significantly associated with infection.

The San Francisco Men's Health Study is a prospective study of the epidemiology and natural history of the acquired immunodeficiency syndrome in a cohort of 1034 single men, 25 to 54 years of age, recruited by multistage probability sampling. At entry, June 1984 through January 1985, the seropositivity rate for human immunodeficiency virus (HIV) infection among homosexual/bisexual study participants was 48.5%. No heterosexual participants were HIV seropositive. Among homosexual/bisexual men reporting no male sexual partners in the two years before entry into the study, seropositivity was 17.6%. For those reporting more than 50 partners, seropositivity was 70.8%. Only receptive anal/genital contact had a significantly elevated risk of HIV infection. Douching was the only ancillary sexual practice that contributed significantly to risk of infection. (<i>JAMA</i>1987;257:321-325)
