Stimulation of the prostate can provoke the release of HIV into semen, even in men who are taking HAART and have undetectable viral load in their blood, according to a small study reported in the July 23rd edition of AIDS. The study investigators believe that their findings could have important implications for HIV prevention and speculate that prostate stimulation (and subsequent HIV shedding) during sex may contribute to the high HIV infection rates seen in gay men.
