It is not possible for women to get pregnant from swallowing sperm since there is no connection between the stomach and the uterus, fallopian tubes or ovaries. However, sexually transmitted infections (STI) can be passed through oral sex. Barriers such as condoms and dental dams can help make oral sex safer, but they don’t prevent you from getting an STI 100% of the time.
Semen is not poisonous. If you swallow your own semen or someone else’s it is safe as long as it is STI-free! If you or your partner(s) has symptoms of an STI, you should not have any kind of sex–including oral sex–until you see a health care provider. Tell your provider that you are having oral sex so that they can check you for infections and answer any questions you may have.
