A 17-year-old male asked:

Saliva kill sperm? If it does how long does it take?

Swallow: Swallow it and move on. There is no scientific study that has looked at this. If you are concerned after performing oral sex on a man and getting his sperm in your mouth then you may brush your teeth or use a mouthwash. There is absolutely no medical concern here.
