Oxygen is toxic to sperm and leads to decreased sperm function and death. This is in addition to the detrimental effects of air on sperm as the semen dries when the ejaculate is exposed to the environment. When does sperm die, and how fast does sperm die when exposed to oxygen and other factors?
Semen is a sperm carrier in the male reproductive system. Sperm takes about 3 months to mature, and has a short life after excretion. The sperm life entering the female reproductive system is longer than that without entering.
Can you get pregnant from semen on hands? What if you wash your hands? Your bed?

The length of time they stay alive has a lot to do with environmental factors and how fast they dry up. If you ovulate shortly after you finish your period, the sperm may still be alive and can fertilize the egg.
I was just wondering if you could tell me how long semen can survive outside of the human body. My girlfriend is worried as some semen got on her hand and about 10 minutes later she touched her vagina. There was no intercourse and no genital contact.

Update: A previous version of this article contained quotes from an expert whose credentials are now in question. We have reached out to him for confirmation of those credentials and have not heard back. But how much do you really know about sperm? We debunked some common myths about sperm that you probably still believe.
Precisely how long they can survive depends on the environment that they are released into and how quickly the fluid surrounding the sperm cells dries up. After ejaculation, sperm can live inside the female body for around 5 days. The fluid in a woman's reproductive tract has all of the nutrients that sperm need for their survival during that time.
Some die within minutes, and some can live anywhere up to seven days, under perfect conditions. But most live about two or three days inside the female reproductive system, according to USC Fertility. You need just one sperm to make it to the right place — the correct fallopian tube — at the correct time — after ovulation — to create a new life.
