Most people don’t know the survival time of sperm outside the body. First of all, we must have a certain understanding of it. The semen excreted by a normal man contains tens or hundreds of millions of sperm. When the sperm is just ejaculated outside the body, the temperature is around 35 degrees and lower than 37 degrees, and it can survive for about a day. Like large hospitals, sperm in refrigerated sperm banks will last longer. Do you know how long sperm survives outside the body? Experts will answer for you:
Although a normal sexually mature man discharges tens of millions or even up to 200 million sperm in one ejaculation, most of these sperm 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 part of the sperm escapes and continues to move forward. When sperm rush up to the uterine cavity, their number is only 1-5 of that during ejaculation. Why is this? Because the sperm remaining in the semen during ejaculation can be protected by a large amount of fructose and sugar-degrading enzymes in the semen. , when the sperm enters the uterine cavity and leaves the semen, its living conditions are far inferior to those in the semen, so the life span is greatly shortened. Sperm with poor quality run slower and cannot reach the uterine cavity quickly, so they lose their sperm. vitality. After passing through many checkpoints, very few sperm are left that can finally reach the fertilization site of the fallopian tube.
However, as long as sperm enters the fallopian tube, it has a strong ability to fertilize. Of course, only 1-2 sperm are lucky enough to be able to combine with the egg in the end, and the rest of the sperm die within 24-36 hours.
