Hiv infection oral sex studies

As the risk of transmission through oral sex is estimated to be much lower than for vaginal and anal intercourse in the absence of antiretroviral therapy, it is implausible that the risk of transmission through oral sex is not affected in the same way as other sexual transmission risks when effective treatment suppresses viral load. When HIV is not fully supressed, the risk of HIV transmission through the mouth is certainly smaller than through vaginal or anal intercourse. If undamaged, the tissues of the mouth and throat are thought to be less susceptible to infection than genital or anal tissues, and an enzyme in saliva also acts to inhibit HIV. Very few cases of transmission through oral sex have been reported amongst gay men despite the continued practice of oral sex often with ejaculation into the mouth by large numbers of men over many years. There are no reliable reports of HIV being transmitted from the mouth to the genitals.

Can You Get HIV from Oral Sex?

Over 19, instances of unprotected oral sex did not lead to a single case of HIV transmission amongst a cohort of HIV-negative Spanish heterosexuals in a sexual relationship with a person with HIV. The study, conducted between and June , is reported in the June edition of AIDS and adds to the growing number of studies which suggest differing levels of risk of HIV transmission from oral sex when compared to anal or vaginal intercourse. Both members of the couple were monitored at the clinic every six months and the HIV-negative partner was tested for HIV.
