What is the general survival rate of sperm?

I believe everyone knows that after male ejaculation, sperm will enter the female uterus through the fallopian tube, but many people do not know how long sperm can survive. This is common sense, so it will not do you any harm to understand it, and it can also help you to understand this knowledge correctly. So let's take a closer look below. I believe you will find it very magical after knowing it.

Although a normal sexually mature man can release tens of millions or even up to 200 million sperms in one ejaculation, most of these sperms lose their vitality and die in the acidic environment of the female reproductive tract. Generally speaking, the life span of sperm in the vagina does not exceed 8 hours, and only a small number of sperms escape and continue to move forward.

When sperms rush up to the uterine cavity, their number is only 1%-5% of that at the time of ejaculation. Why is this? Because the sperms that remain in the semen during ejaculation can be protected by a large amount of fructose and enzymes that break down sugars in the semen. When the sperms enter the uterine cavity, they leave the semen, and their living conditions are far worse than in the semen. Therefore, their lifespan is greatly shortened. Sperms of poor quality move slowly, cannot reach the uterine cavity quickly, and lose their vitality.

After passing through so 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.

I believe that now you already know how long sperm can survive, which will be very helpful for your future process of having children. However, the number of sperm in a man's lifetime is limited, so it is recommended that male friends should not have too many sexual intercourses, otherwise it is likely to cause poor health.
