How long can sperm survive in a woman's body?

For a woman to successfully become pregnant, not only does she need her egg cells to be of excellent quality, but also her sperm to have strong fertilization ability. After a man's sperm enters a woman's body, the time it survives in the woman's body is uncertain. Generally speaking, only a very small number of a man's sperm can fuse with the egg cell to form a sperm-egg combination. How long does a man's sperm live in a woman's body?

Generally speaking, the lifespan of male sperm in a woman's vagina does not exceed 8 hours. Then only a small fraction of the male sperm will escape and move forward again. Why is this happening? Because the sperm in the semen during ejaculation can obtain a lot of glucose and sugar-dissolving enzyme protection in the semen, and when the sperm enters the uterus, it leaves the semen. The living environment at this time is far worse than that in the semen, so the lifespan is greatly shortened. Poor quality sperm moves slowly and cannot reach the uterine cavity quickly, thus losing its vitality.

So, after the male sperm enters the female body, how long can the male sperm survive in the female body? Experts suggest: After the male sperm goes through the tube copy, only a few male sperm can finally reach the bilateral fallopian tube fertilization site. However, as long as the sperm enters both fallopian tubes, it has a stronger fertilization ability. Of course, in the end only 1-2 sperm are lucky enough to fuse with the egg, and the rest of the sperm die one after another within 24-36 hours. Only the sperm stored in the folds of the cervical mucosa can live for 2-6 days. Even so, its fertilization ability is basically lost, because the fertilization ability of sperm can only last about 20 hours.

The fertilization ability of the egg is strongest within 15 to 18 hours after being released from the ovary, and can maintain the fertilization ability for about 30 hours. After that, the egg begins to change, and the fertilization ability quickly weakens and disappears.

Although sperm ejaculated into the female reproductive system can survive for up to 4-5 days, its strong fertilization ability lasts for 1-2 days. In other words, pregnancy is only possible if sexual intercourse occurs within 1-2 days before and after the female ovulation period. This is very important for guiding infertile couples in their sexual life. Some couples have no problem conceiving each other, but they become infertile for many years after marriage because they ignore the opportunity to get pregnant.

According to the description in the article, we can understand that the survival ability of male sperm in the female body is different. The shortest may only have a lifespan of eight hours, and the longest is only 2-6 days. It is also very rare that it can combine with the egg cell to form sperm-egg fusion.
