Do urination kill sperm?

Question

My b/f last nite masturbated then got up to use the restroom, he urinated and then came back to bed. About an hour later he was rubbing himself on me and entered me very quickly but did not ***, is there a chance that could have gotten me pregnant I thought urination kills sperm?

Answer 1

The chances are slim.  Urination will wash away the majority of s***n, however some could have survived.  I wouldn't worry about it too much.

Answer 2

No, the s***n would not have survived for that period of time out side of the body, or in the p***s for that matter, and yes the acid in urine alone would kill off any leftover sperm in the urethra  

Answer 3

All it takes is one of those little guys that made it upstream. Urine does NOT kill sperm. If it did, women would never get pregnant. There's always a bit of urine in the urethra/cervix. You might be thinking that urine is sterile, which it is. Wounded men in war are told to put urine on injuries to sterilize their injury. That's a different thing entirely.

Answer 4

Slim chance if he didn't ejaculate inside you.  

...though sometimes, nature finds a way.
