Its it true that air kills sperms?

What has made you ask that ? If you look it up on tinternet it should say but I read it lives up to 5 days but then again I am still unsure

I believe it is suppose to live up to five days inside the woman, not out in the air. And what a weird question. This is not a good form of birth control. If that's what you think. Gee, I don't know what you are thinking.
