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. Cases of transmission via cunnilingus are extremely rare, and the reliability of these reports is questionable.
Can HIV be transmitted through oral sex (fellatio and cunnilingus)?
HIV from oral sex: Possibility, risks, and prevention
The chances of transmitting HIV through oral sex are very low. It is also possible to take further preventive measures, such as using a condom. HIV is a virus that spreads through bodily fluids. A person can contract HIV through direct contact with infected fluids or sharing syringes with someone who has the virus. In this article, we discuss whether it is possible to transmit HIV through oral sex and provide some tips for prevention. However, it can potentially happen if someone with HIV ejaculates into the mouth of their sexual partner.
Can You Get HIV from Oral Sex?
The virus is transmitted between partners when the fluids of one person come into contact with the blood stream of another person. This contact can occur from a cut or broken skin, or through the tissues of the vagina, rectum, foreskin, or the opening of the penis. Oral sex ranks very low on the list of ways HIV can be transmitted. However, the risk of contracting HIV through oral sex is not zero.
Oral sex involves using the mouth to stimulate the penis fellatio , vagina cunnilingus , or anus anilingus. However, it is hard to know the exact risk because a lot of people who have oral sex also have anal or vaginal sex. The type of oral sex that may be the riskiest is mouth-to-penis oral sex. But the risk is still very low, and much lower than with anal or vaginal sex.
