How long does the sperm survive out side the body ?

Semen: During workups for infertility we usually recommend that semen be examined within a 30 minute window. Semen loses viability very rapidly outside the body.

Not long unfrozen: Sperm ejaculated outside the body might survive in semen, the fluid released during ejaculation, up to a few hours. Sperm can be preserved for weeks when semen is stored at a lowered temperature, ...Or years when semen is frozen, such as those in a sperm bank.
