How long sperms could survive after ejaculation?

Sperm survival after ejaculation varies depending on the environment:

Inside the Female Reproductive Tract :  Sperm can survive for **3 to 5 days** in the female reproductive tract, particularly in the cervical mucus, which provides a suitable environment for sperm viability.

Outside the Body : Once exposed to air, sperm can survive for a very short time. On dry surfaces, they typically die within **a few minutes**. In a moist environment, such as on a wet surface, they may survive for a bit longer, but generally not more than **30 minutes to an hour**.

In Semen :  In semen, sperm can remain viable for a longer period, but once the semen dries, the sperm will die quickly.
