Some HIV-negative men in long term relationships with HIV-positive men have an antibody response in saliva which may inhibit HIV infection, report Swedish researchers in an article published online ahead of print in AIDS. This is the first time that such a response has been described in saliva, and may help explain why infection through oral sex is somewhat infrequently reported even in serodiscordant couples.
While it is well established that while HIV infection during fellatio and other types of oral sex can and does happen, the number of infections that can be attributed to oral sex is relatively small in comparison with the number of times that unprotected oral sex is practiced. One reason is that saliva contains enzymes which partially inhibit HIV infection.
