Can HIV be transmitted through semen during oral sex?

Yes, it can. HIV can be transmitted through the exchange of body fluids (e.g. blood, semen, saliva, and vaginal secretions). HIV is transmittable through all forms of sexual intercourse (oral, vaginal, and anal) when one or both partners are infected with HIV. Oral sex without a latex condom places you at risk of exposure to HIV. It should also be noted that pre-ejaculation fluid can carry HIV and it can be absorbed into the thin mucous linings of the mouth. The Center for Disease Control (CDC) recommends that during oral sex, a latex condom should be used to decrease risk of exposure.
