How long does male sperm survive?

When we can understand some common sense of reproductive health, then for couples who want to conceive, we can greatly increase the chances of conception, such as understanding the survival time of sperm. After the sperm enters the female body, fertilization is possible within 20 hours.

1. Because the sperm in the semen during male ejaculation contains a lot of fructose and enzymes that decompose sugar, these substances can protect the sperm. After the sperm enters the uterine cavity, the sperm separates from the semen. The living conditions in the uterine cavity are far worse than those in the semen, so the sperm will quickly lose vitality after leaving the semen. As the sperm loses vitality, it swims slower and slower, and finally dies before reaching the uterine cavity.

2. So, how long can sperm live after entering the female body? Professionals say: Sperm passes through many places, and finally there are very few sperm that can reach the fallopian tube and be fertilized. However, as long as the sperm enters the fallopian tube, there is a great possibility of fertilization. Of course, in the end only 1-2 sperm are lucky enough to combine with the egg, and the other sperm will basically die in one or two days. Only sperm stored in the crypts of the cervical mucosa can live longer, but basically no more than 6 days. Although it is alive, it has no ability to fertilize. Sperm can only be fertilized within 20 hours.

3. The egg is most likely to combine with the sperm within 15 to 18 hours after it is released from the ovary, and this period can last up to 30 hours before the egg gradually changes sex and loses the possibility of fertilization.

4. Although the sperm ejaculated by the male into the female reproductive tract has a long or short life span, it has a strong fertilization ability for 1 to 2 days. So what this tells us is that effective fertilization can only be achieved if sexual intercourse is performed within one or two days after the female ovulates. This is very important for couples who want to get pregnant, so as to avoid missing the best time and causing the misunderstanding of infertility.
