Does sperm get killed by water?

Yes. Chlorine kills all bugs including sperm. Hello. Chlorine in a swimming pool will not kill sperm. Spermicidal jelly or condoms will kill sperm. Sperm dies naturally a few hours after coming into contact with air. Sperm can live for up to 5 days inside a womans body. Yes, it will. But, if he comes directly inside you it won't kill them before they can get to the safe area inside your uterus. If he comes into the water instead you are safe though.
