Introduction to sperm maturation

Men produce sperm every day, so many people may wonder when sperm matures. Which days are the days of sperm maturation?

As for the maturation period, many people may think that sperm and eggs have a maturation period. In fact, it is not contaminated. Then,

This article will introduce it to you.

Mature male reproductive cells. They are generally divided into three parts: head, middle section, and tail. The head is mainly composed of the cell nucleus, the middle section contains the

The centrosome and mitochondria, from which the flagella are generated, constitute the tail. Sperm of humans and most multicellular animals occurs in the testis

The seminiferous epithelium in the seminiferous tubules has two types of cells: a large number of spermatogenic cells at various stages of development and a small number of columnar

Support cells.

When male puberty begins, spermatogenic cells at all levels develop and mature, and active sperm appear. The sperm development and maturation process can be divided into the following order:

It is divided into three stages: ① Reproduction stage: The primitive, undifferentiated early spermatogonia divide and reproduce.

② Growth stage. Some spermatogonia no longer divide and grow into primary spermatocytes. ③ Maturation stage. Primary spermatocytes further

After two meiotic divisions, the spermatocytes mature into two secondary spermatocytes.

After one meiotic division, it becomes four sperm cells. In the second meiotic division, each chromosome is divided into two chromatids, and then

The sperm cell is then divided into sperm cells. During the process of sperm cell transformation into sperm, the cell nucleus becomes the sperm head.

The intratesticular dilator stays for 2 weeks, and continues to develop and mature, gaining fertilization ability. During the spermatogenesis process, spermatogenic cells at various levels are sensitive to certain factors.

The sperm production process is very sensitive to the influence of temperature, radiation, hormones, drugs, diseases, etc., which can all cause abnormalities or stagnation of the sperm production process.

Everyone knows that sperm matures every day. The sperm matures every day. Under normal circumstances, under the premise of good health,

We all produce a healthy and mature sperm every day. If you are planning to conceive, you should go to the hospital for a checkup immediately.
