How long does it take for sperm to form accurately?

Each male sperm will grow in the male body for about 4 to 5 days. Almost from the beginning, the male body structure is formed. Every day, tens of thousands of sperm are produced, but not every sperm will survive. During sexual intercourse, the male will ejaculate sperm into the female vagina through the genitals, and only about 1 to 2, or 3 to 4, will survive. So how long does the sperm travel is the most accurate?

There is a pair of "Li Sheng brothers" in the scrotum, one on each side, called testicles. Although there is a "wall" between them, their functions are the same. Just like two kidneys, sometimes one can still complete the task of urination without one, if one testicle is missing for some reason, the other can also take on all the responsibilities.

The human embryo has formed testicles and started to work in the 7th week. The testicles are pink, shiny ovals, weighing about 15 grams, and each testicle has a volume of about 15 to 25 cubic centimeters. Most adult men of the Han nationality have a volume of 20 cubic centimeters, and Westerners have slightly larger testicles than Chinese people.

If you cut open the testicle and take a look, you can see that there are 200 to 300 testicular lobules inside, and each lobule contains 3 to 4 small curved tubes, which are called convoluted seminiferous tubules. The diameter of the tubules is only 150 to 250 microns, but the length is 30 to 70 centimeters. If the nearly 1,000 convoluted seminiferous tubules in the testicle are connected, the total length is about 500 meters. These small tubules finally merge into a main tube, which goes to the epididymis and vas deferens.

For individuals, testicles are the decisive factor that makes a man a great man; for humans, testicles are the necessary condition for us to last forever.

The ability of the testicles is to produce sperm. They are the sperm factory. In the seminiferous tubules, there are reproductive cells. Under suitable conditions, these reproductive cells will evolve into sperm. The growth cycle of human reproductive cells takes about 61 to 64 days. Sperm is the creator of life, and its importance is known to everyone.

Normally, the testicles produce 50 million sperm every day, which means that in just over three months, the testicles can produce 5 billion viable cells, which is close to the total population of the world. Naturally, although the testicles work hard to produce sperm, only one or a few of them can really play a role in the end.

There are many mysteries in the male body. Generally speaking, from the perspective of anatomists, a male's sperm can produce 200 testicular lobules, and the number of sperm ejaculated every day through the winding small tubes is in the tens of thousands. Therefore, sperm is very important and everyone needs to understand this process.
