The survival time of male sperm in the body is divided between the male body and the female body, while the survival time in the female body varies depending on the site. The male testicles produce new sperm every day and they usually survive in the male body for about 3 months. After ejaculation into the female body, the pH level in the female vagina is normally 3.5-4. In this acidic environment, most sperm have a very short survival time, probably only 2 hours. If the sperm can reach the woman’s uterus, they can survive for about 3 days. In the fallopian tube, the survival time of sperm can be 4-8 hours. In conclusion, the survival time of normal male sperm in the female body is relatively long, so if you are not prepared for pregnancy, it is recommended to take contraceptive measures such as condoms when having intercourse to avoid unwanted pregnancy.
