We all know that it takes sperm and egg to combine to have a child, but I’m afraid there are more facts about sperm and egg that many people may not be aware of. For example, do you know how long a sperm can live after it leaves the body? The data tells us that sperm can only survive outside the body for about half an hour, while in the female reproductive tract it can survive for about 24 to 72 hours, that is, half a day for sperm moving in the vagina and two to eight days for sperm moving in the cervix. Sperm in the uterus and fallopian tubes can survive for about two to two and a half days. Sperm in the underwear can only survive for about half an hour, and in the male genitalia for a few weeks. About how long sperm survive outside the body depends on the temperature, if the temperature is lower, the semen can survive for a few weeks. If the temperature is very high, it can only exist for about half an hour, but if it is frozen in liquid form, it may appear to be preserved for a long time, such as a type of frozen sperm procedure that is very popular nowadays. So generally the sperm survives in the body for about 15 to 30 minutes, and still at a high temperature. The survival rate of sperm outside the body is quite low, and it cannot be implanted directly into the female vagina for fertilization, and sometimes a deformed sperm may occur.
