How sperm is produced

In fact, every child is the magical product of the combination of sperm and egg. Sperm is the reproductive cell of men after development and maturity. It is formed from immature spermatogonia. Sperm is a special product unique to men. Men produce a large number of sperm every day, at least tens of thousands, or even hundreds of millions of sperm every day. So how are sperm produced?

Sperm is an important sign of a fully mature male, and it lasts for a long time, generally throughout adulthood. The formation and production of sperm requires specific conditions and processes. So how are sperm produced?

How sperm is produced

Sperm is the mature reproductive cell of males. Their development starts from immature spermatogonia. Spermatogonia divide many times and increase in size to become spermatocytes, which divide again to become spermatids, and finally develop into mature spermatozoa, that is, primordial cells-spermatocytes-spermatocytes-spermatozoa.

After sperm matures, it falls into the lumen of the seminiferous tubules and slowly migrates to the epididymis. Some of it is stored there, while most of it migrates to the vas deferens and its ampulla for storage until it is expelled during ejaculation.

During the formation of sperm, a suitable and relatively constant environment is required, and temperature is an important condition for sperm production. This suitable and relatively constant environmental temperature is regulated by the expansion and contraction of the scrotum. When the outside temperature rises, the scrotum expands and expands the heat dissipation area to cool down; conversely, when the outside temperature drops, the scrotum shrinks to keep warm. Through this regulation, the temperature inside the scrotum is kept 1.5-2.0℃ lower than the abdominal cavity.

2. Human sperm production is a continuous process. Sperm is produced every moment, which means that there are mature sperm in the body at all times. This is obviously different from the fact that only one egg matures every month in women.

An adult produces about 10 million sperm per gram of testicular tissue per day. The testicles on both sides weigh about 30 to 40 grams, so the number of sperm produced every day can reach hundreds of millions.

The development and maturation process of sperm is the development and maturation process of testicular germ cells. The production of sperm is a sign of male developmental maturity and continues throughout adulthood. The testicles in the human body must continuously produce immature germ cells, that is, the regeneration of spermatogonial stem cells themselves, so that the production of sperm has the reserve capacity, which is necessary for spermatogenesis.

The epithelium of the seminiferous tubules is composed of spermatogonia and supporting cells. During puberty, the testicles are stimulated by the pituitary gonadotropin, spermatogonia begin to activate, spermatogonia continue to proliferate and develop, and evolve into sperm.

The production of sperm begins with the regeneration of undifferentiated spermatogonia and the division and proliferation of spermatogonia. After several mitotic divisions, part of the spermatogonia grows into primary spermatocytes, while the other part remains as stem cells. The primary spermatocyte undergoes the first maturation division to form two secondary spermatocytes, which undergo the second maturation division to form two sperm cells. Sperm is a cell with a special morphology, divided into three parts: head, body, and tail. The head participates in fertilization, and the flagella movement of the tail makes the sperm motile. It takes about 11 to 16 days for sperm to be stored and moved in the epididymis, further maturing and having stronger motility. The epididymis provides a favorable environment for the storage of sperm before ejaculation, and accessory gland secretions such as prostatic fluid and seminal vesicle fluid participate in the ejaculation process.

After reading the above question about how sperm is produced, I believe everyone has a general understanding. In fact, the formation of sperm requires a proper environment and temperature. Therefore, men should protect their reproductive organs, testicles and penis, so as to ensure the quality of sperm.
