Where Does Men's Egg Pain Really Pain? Explain the Little Secret of Men's Reproductive Organs

In the life of both sexes, the male reproductive organs play a leading role, but if you don't understand the reproductive organs of both sides, the sexual life will also be tasteless. What is the male reproductive organ? Let me introduce to you how the male reproductive organs are.

What is the male reproductive organ?

testis

It is commonly known as "egg, which is one of the most vulnerable genitals of men," and the word "egg pain" is also derived from it!

The internal structure of the testis is surrounded by a layer of tough tissue, called the white membrane, which has the function of protecting the testis. The white membrane thickens and extends inward, dividing the testis into many small compartments. These compartments are called testicular mediastinum, and the compartments are called testicular lobules. Normal men generally have 200~300 lobules, which are filled with testicular substance and are the place where sperm is produced, called convoluted tubules. If you cut a small piece of testicular parenchyma and put it under the microscope for observation, you can see that the seminiferous tubules are thin tubes.

In adults, the diameter of each seminiferous tubule is 150~250 microns, the length of each tubule is 30~70 cm, and the longest tubule can reach 150 cm. There are 300~1000 seminiferous tubules in a testicle, with a total length of 200~300 meters. It is obvious that the base of testicular sperm production is quite large. The seminiferous tubules in each testicular lobule are combined into 2~3 straight seminiferous tubules, forming a testicular network, which is then combined into 15~20 testicular output tubules that are connected with the epididymis, through which sperm enter the epididymis and mature. The seminiferous tubule is the base of sperm production. Such a small pipe has such magical ability. Why? It's really hard to solve its doubts. There are quite complex subtle changes in cell biology and biochemistry. Up to now, scientists are still painstakingly exploring their fate. Nevertheless, the basic process of sperm production has been recognized.

semen

Semen is not a kind of reproductive organ, but it is an important product of male genitalia, which is the unique "essence" of men!

After sperm is produced by the testis, it develops and matures in the epididymis and stores in the epididymis and near the epididymis of the vas deferens. It generally takes 74 days for sperm to be produced in the testis and 16 days to mature in the epididymis, which takes about 3 months in total. The duration of sperm survival in the reproductive tract is generally 28 days, and if stored too long, it will become old and lose vitality. The testicles of men begin to produce sperm when they are about 14 years old. When they reach sexual maturity at the age of 16 to 17 years old, spermatorrhea will occur; After the age of 40, the spermatogenic ability gradually decreases.
