How long does it take before sperm dies? Does pre-ejaculated sperm have the same life span? Does it die once it hits the air or does it take a while to die?
Thanks for asking!
The life span of sperm once a male has ejaculated (cum) can vary. In the vaginal canal (where a tampon would go or where a penis would go during vaginal sex), sperm can only live a few hours. Once inside the fallopian tubes (where sperm and egg meet to create a pregnancy), they have a life span of about 5 days. Sperm not ejaculated inside a woman’s body (maybe on the sheets or something) can live for up to an hour though usually die within minutes. The sperm in pre-ejaculatory fluid has a similar life span.
Hope you have a wonderful day! Keep the questions coming!
In happiness & health,
