Where is a man's sperm produced?

Male friends' sperm is produced in the testis, that is, in the testicle. Male friends should understand the formation of sperm and the factors that affect it, because this is a kind of protection for sperm. Generally speaking, sperm is greatly affected by temperature.

What is sperm

Sperm refers to the mature male reproductive cells, which are formed in the testis.

Sperm survival time

Although a normal sexually mature man can discharge 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 sperm escape and continue to move forward. When the sperm rush up to the uterine cavity, their number is only 1%-5% of that at ejaculation. After passing through various checkpoints, there are only a few sperm that 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. However, 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.

How sperm is produced

An adult male can produce 70 to 150 million sperms every day. Sperm are produced in the testicles and take about 10 weeks to mature. They are then stored in the epididymis. The temperature must be 3 to 5 degrees Celsius below body temperature to produce a large number of healthy sperms.
