HivPlusMag reports:
A study published online in advance of release in the print journal AIDS shows that oral sex may actually help prevent HIV infection in sexually active gay men.Researchers in Sweden studied several gay male couples in which one partner is HIV-positive but not taking anti-HIV medications and the other partner is HIV-negative. They found that many of the HIV-negative men who were repeatedly exposed to HIV through the semen or preseminal fluids of their HIV-positive partners during oral sex developed an antibody response in their saliva that neutralized the virus.
The researchers believe that repeated exposure to HIV during oral sex leads to the production of the antibody IgA1 in the saliva, which has been shown in previous studies to have an anti-HIV effect.
If this study holds up, will there a better reason to give head?
