How long does sperm survive in the body?

There are many common problems with male sperm, the most common of which is sperm deformity, which has a great impact on fertility. In this case, men need to receive timely treatment to avoid further damage to their own fertility. But how much sperm can survive in the body is something many women do not understand. The following is a detailed introduction so that you can have some understanding of this situation and know what to do when women are preparing to become pregnant.

Sperm survival in the body:

Generally speaking, the life span of sperm in the female vagina does not exceed 8 hours. After that, only a small number of sperm will escape and continue to move forward. Why is this? Because when a man ejaculates, the sperm in the semen can be protected by a large amount of fructose and enzymes that decompose sugar in the semen. When the sperm enters the uterine cavity, it leaves the semen. At this time, the living conditions are far worse than in the semen, so the life span is greatly shortened. Poor quality sperm moves slowly and cannot reach the uterine cavity quickly, and loses its vitality.

So, after sperm enters the female body, how long can it survive in the female body? Experts say: After passing through many checkpoints, only a few sperm can finally reach the fertilization site in the fallopian tube. However, as long as the sperm enters the fallopian tube, it has a strong fertilization ability. Of course, in the end only 1-2 sperm are lucky enough to combine with the egg, and the rest of the sperm will die within 24-36 hours. Only the sperm stored in the crypts of the cervical mucosa can live for 2-6 days, even so, its fertilization ability has been basically lost, because the fertilization ability of sperm can only be maintained for about 20 hours.

Although sperm injected into the female reproductive tract can survive for up to 4-5 days, its fertilization ability lasts only 1-2 days, which means that conception is only possible if sexual intercourse occurs within 1-2 days before or after ovulation.

After understanding the survival time of sperm in the body, women need to understand their own ovulation period in order to be able to get pregnant easily, so that they can get pregnant smoothly. Men also need to adjust their bodies before getting pregnant. Smoking and drinking are not options, otherwise they will have a great impact on sperm.
