That is a myth. Sperm can survive outside of the human body. Doctors have reported sperm outside of the body living for as long as several hours, depending on the environment.
In the right enviroment, sperm are resilient little buggers. For instance, they can survive a whole week inside of a women's body. If they don't have the protection of a human body, man or woman's, they usually die between a 1/2 hour and four hours. Basically, you can be certain sperm in dead, when the semen is dry. Dried sperm is dead sperm. [ Razhie's advice column | Ask Razhie A Question ]
