Testicule - what is it? Structure and function of male testicles

Testicles are often called male testes - an incredibly important part of the male body and the reproductive system in particular.

In ancient times, when a man swore that he would speak only the truth, he touched his testicles. If a man had both testicles, then this was the main sign of his masculinity. Many people are interested in the question: "Testicule - what is it?". Let's look at this article.

Eggs are always isolated from each other and located in the cavity of the scrotum. Each of them is covered with special shells. They are specific structures with seminal ducts. It is in them that the process of spermatogenesis takes place. Spermatozoa that are ripe, move into the appendages, and then are ejected during ejaculation.

Interesting fact

Some asymmetry of the testicles in men is a standard phenomenon. That is, it's normal, there's nothing to worry about. It in no way has absolutely no effect on the fertility of a man. Scientists believe that this asymmetry can be a protective reaction, which reduces the risk of simultaneous trauma of both testicles. Although many representatives of the strong half of humanity are worried about whether everything is properly arranged and whether everything functions correctly.

Often there are men who experience because one testicle can be larger than another. But such experiences are superfluous. Different in size testicles - a common phenomenon. Their weight can vary from 25 to 50 grams.

So, the testicle - what is it? What effect does it have on the process of spermatogenesis in the male body? About this further.

The testicles are male gonads, which produce testosterone and sperm.

The temperature that is optimal and necessary for the process of spermatogenesis is ensured by the placement of a testicle in the male scrotum. Wearing very tight and dense underwear, as well as abuse of hikes in baths and saunas can cause infertility. In addition, modern inventions, such as heated car seats, can affect the male health. It is better not to abuse this comfort.

In carrying out studies of the most important functions of male testes, you can gather very valuable information related to the treatment of infertility. If you analyze the composition of sperm, you can determine the various causes of infertility in men. Timely diagnosis, in turn, allows you to take appropriate measures in the treatment.

Structure, anatomy and size

Male testicles are rather complicated. This is due to their important purpose. They distinguish the lower, upper, posterior end and its middle part. To the rear, epididymis adjoins.

Eggs are paired organs, which have a slightly flattened oval shape. Before full masculine maturation occurs, the appendages and testes develop very slowly, but then their development is greatly accelerated.

Covered with a shell, from which the partitions leave. They subdivide the organ into lobules - each contains 270 pieces.

Structure and function of the testes

• Each of the 270 lobules contains from one to three seminal channels of crimped form and a length of up to 75 centimeters (it is the process of spermatogenesis that occurs in them). The total length of such tubules can reach about 500 meters. The shape of the canal is straightened by the mediastinum, and the channels pass into the testicle network, which is located in the testicular plexus.

• The channels of this plexus have 15 channels of enduring, they enter the appendages of the testicles (epididymis), thus forming a head. The ability of fertilization appears in spermatozoa only after they pass along the epididymis.

• Adjacent channels smoothly flow into the duct, which displays the seed. The vas deferens simultaneously constitutes a part of the seed rope. This duct goes to the bladder through the wide inguinal ducts. It is in the region of the bladder that the two vas deferens approach the maximum.

• The vas deferens (male testicle) widens slightly at the end, which forms the ejaculatory duct. Its length is about two centimeters. It crosses the prostate and opens with a narrow opening on the tubercle of the canal, intended for the release of urine.

Now it is clear what it is - testicles. It has an excellent supply of blood, in connection with which a sufficient exchange of metabolites and hormones is achieved. It also allows you to adjust the temperature. The testicle temperature in a man is slightly lower than the normal temperature of the entire body, about a half degrees. And the temperature of the skin on the surface of the scrotum is even lower - by three and a half degrees lower.

Thanks to the following two mechanisms, it is possible to maintain the lower temperature of the male scrotum and testicles in it:

1. The skin of the scrotum is very thin.

2. A specific vascular plexus, in which the arteries located between the testicle lobules thickly adhere to the veins.

The structure of the male testis at the cellular level

14% of the total volume is occupied by fat interstitial tissue. It, in turn, consists of fatty cell connections, Leydig cells, capillaries, connective tissue, fragments of macrophages.

70% of the total volume of male testes occupy the seminal canals, which consist of three types of somatic cells: peritubular cells, Sertoli cells, spermatogenesis cells.

The white membrane. Testicle with her. It is located in the visceral and parietal sheets. Together they form a shell associated with beams of muscle nature. These bundles sufficiently effectively hold the testicles, thereby avoiding concussions.

The white membrane is located near the testicular posterior margin and has a specific thickened structure. From this thickening, the septa that form the connective tissue depart. They divide the testicle into a large number of lobules.

Standard testicle size

The eggs of the average man should be no less than the sink.

The normal size is four centimeters in length and three centimeters in width.

There are situations that men are worried about the size and location of their own testicles. If they differ from each other by no more than one centimeter, and there are no painful sensations, then there is no cause for concern. But if the deviation is more than one centimeter, it is best to contact a specialist urgently.

What is the effect of the size of the paired organ?

There is an opinion that the working capacity of the testicles depends on their size. This is in part true. As an example, consider a chimpanzee. The size of their testicles is larger than that of gorillas, and chimpanzees have much more sexual intercourse than gorillas. However, scientists did not conduct exact studies in this area. It is not a secret that black men have testicles that are twice as large as the testicles of Asian men. But if you compare the ability to fertilize Asians and blacks, it becomes clear that fertilization does not depend on the size of testicles in men.

The main function of the testicles

The main function of the testes is the process of producing the main male sex hormones and other active substances, as well as endocrine and generative functions. The formation of the hormone testosterone is the main purpose of the endocrine function. In the body's blood, it comes from the testicles.

They carry out the most important function of the secretory organ - they supply the hormones that are produced in the blood. In addition, they have a function of internal secretion - produce and remove sex cells.

What does the level of testosterone in the body affect?

• Under the influence of testosterone, the body develops according to the normal male type: the special structure of the larynx, the increase in the thickness of the vocal cords in men, and the hairline.

• Growth and proper development of appendages and prostate, male seminal vesicles.

• Development of the musculature of the body.

• The formation of male libido.

• Growth and proper development of external genitalia.
