Oral Sex Is Generally Safe, but STI Risks Remain
Is Oral Sex Completely Safe? An Expert Explains Why It Can Have Health Risks · news18.com

When someone swallows semen, it goes into the stomach and is broken down like other substances.

It does not travel to the uterus or ovaries, so swallowing it cannot cause pregnancy.

Pregnancy can be possible if semen gets into or near the vagina.

Semen is not proven to provide special nutrition or health benefits.

Oral sex can spread some sexually transmitted infections, even when a person has no symptoms.

Mouth cuts, sores, or bleeding gums may make infection risks more concerning.

Condoms and dental dams can lower the chance of transmission.

A rare semen allergy can cause symptoms such as itching, burning, redness, or swelling.

A healthcare professional can help assess repeated or unusual symptoms.
