HIV and other STIs in oral sex
Page last reviewed 5.4.2024
The risk of HIV in oral sex is very small. However, other STIs are more easily transmitted through oral sex without a condom or dental dam. For example, chlamydia and gonorrhea should also be tested from the pharynx if you have had oral sex without a condom.
The risk of HIV transmission in unprotected oral sex is very low. In oral sex, the one who performs it and has a possibility of getting sperm or vaginal fluids in their mouth has a small possibility of HIV transmission if a condom or dental dam has not been used. Other STIs (chlamydia, gonorrhea, syphilis) can be transmitted to any person in oral sex, including rimming. Chlamydia and gonorrhea should also be tested in the pharynx, if the pharynx could have been infected through unprotected oral sex.
There is no risk of Hepatitis C in oral sex.
