Men's testicles are often referred to as testicles. They are an important part of the male body in general and the reproductive system in particular.
Description of the organ
In ancient times, when a man swore an oath that he would never lie, he touched his testicles. If he had both testicles, then this proved his masculinity. Quite a few are interested in what the anatomy of the testicle is. We will study this issue in this article.
Men's testicles are a paired organ, and they are always isolated from each other. They are located in the cavity of the scrotum and are covered with a special membrane. They are specific structures that have seminal ducts. The process of spermatogenesis is carried out in them. Mature spermatozoa move to the appendages, after which they are released during ejaculation.
Interesting fact
Standard for all men is some testicular asymmetry. This feature is not a deviation, and you should not worry about it. Asymmetry does not have any effect on male fertility. Scientists suggestthat such a feature is a protective reaction that helps reduce the risk of simultaneous tramming of both testicles. However, many men continue to worry about this, thinking that the asymmetry of the testicles affects their functioning.
It is also quite common for men to worry that one testicle may be slightly larger than the other. Such experiences are groundless. Different testicle sizes are normal. The weight of the testicles can also be different - 25-50 grams.
What is the male testicle? What part does it take in the process of spermatogenesis? What is the anatomy of the testis?
So, male testicles are paired gonads that produce the hormone testosterone, as well as germ cells - spermatozoa.
The location of the testicles in the scrotum provides the optimal temperature, which is necessary for the normal process of spermatogenesis. If a man wears very tight or thick underwear, abuses saunas and baths, then this can cause infertility resulting from exposure to elevated temperatures. Some modern inventions can also tell on men's he alth, for example, heated seats in a car. Therefore, do not abuse this comfort.
During the study of the most important functions of the testicles, it was possible to obtain quite valuable data related to the treatment of infertility. Analysis of the composition of semen allows you to identify a variety of reasons why men experience infertility. Diagnostics,carried out in a timely manner, allows you to take appropriate measures in the course of treatment.
Anatomy of the testis
The anatomy of the male testicles is quite complex. This is due to the fact that they have an important purpose. Allocate in them the middle part, as well as the rear, upper, lower ending. The epididymis adjoins the posterior end of the testicle.
As we have already noted, the testicles are paired organs that have a flattened oval shape. Until the full maturation of a man, the development of the testicles and appendages is very slow, however, then there is a significant acceleration in their development.
The testicle is covered with a membrane, and partitions extend from it, subdividing the testicle into special lobules. Each consists of 270 slices. The anatomy of the male testicle is unique.
The functions of the testicles and their structure
• Each of the 270 cloves contains several seminal canals. There may be one, two or three. The seminal canals are convoluted and reach a length of up to 75 centimeters. The process of spermatogenesis occurs in them. It should be noted that the total length of these tubules can reach half a kilometer. At the mediastinum, the shape of the canal straightens, they pass into the testicular network located in the plexus of the testicles. What else does the anatomy of the male testicles include?
• Canals of the testicular plexus have efferent canals, of which there are 15 pieces. The efferent canals enter the epididymis (epididymis), thereby forming the head. Spermatozoa acquire an exceptional ability to fertilize only afterpass along the appendage.
• Next, consider the anatomy of the epididymis. The channels then pass into the duct, which removes the sperm. The vas deferens is also part of the spermatic cord. This duct passes through wide ducts in the groin to the bladder. The maximum convergence of the ducts with each other is observed in the region of the bladder.
• The ejaculatory duct (male testis) expands slightly at the end to form the ejaculatory duct. Its length reaches two centimeters. It passes through the prostate and opens as a narrow opening on the tubercle of the urethra.
The testicles are well supplied with blood, which contributes to a sufficient exchange of hormones and metabolites. Good blood flow also allows you to maintain the required temperature. It is worth noting that the testicles in men have a temperature slightly lower than the temperature of the rest of the body. The difference is about one and a half degrees. In this case, the surface of the scrotum has an even lower temperature. About 3.5 degrees below body temperature. Here is the structure of the testicle. The anatomy of this organ is quite interesting.
Maintaining a lower temperature on the surface of the scrotum and inside the testicles is possible due to two main mechanisms:
1. The scrotum has very thin skin.
2. The presence of a specific choroid plexus, due to the fact that the arteries located between the lobes of the testicles are densely entwined with veins.
Cell structure of the male testicle
Approximately 14% of the total volume is occupied by mast interstitial tissue, which, in turn, consists of Leydig cells, mast cell junctions, connective tissue, capillaries, macrophage fragments.
Approximately 70% of male testicles are composed of seminal ducts, formed by three types of somatic cells, such as Sertoli cells, puritubular cells, spermatogenesis cells.
The testicle is always covered with a protein membrane and fused with it. It is located in the parietal and visceral sheets. In tandem, they form a sheath that is associated with muscle bundles. These tufts support the testicles very effectively, avoiding unnecessary concussions.
The albuginea has a specific thickened structure and is located near the posterior edge of the testicle. Partitions extend from the thickening, which form connective tissue and divide the male testicle into 270 lobules.
The anatomy of the human testicle is well known.
Standard testicle sizes
A man's testicle should be no smaller than a plum. That is, the norm is about three by four centimeters.
Quite often, men worry about the location and size of their testicles. If the difference in size is no more than a centimeter, and at the same time the man does not experience any discomfort, then there are no reasons for worrying. However, if the difference in size is more than a centimeter, then it is better to seek the advice of a specialist.
This is the structure of the testicles in men. Anatomy in detailconsidered. But what are their functions?
The main function of the testicles
The main functional task of the testicles is the production of the main male sex hormones, generative and endocrine function. The main point of endocrine function is the secretion of testosterone. It enters the blood directly from this paired organ.
The testicles also carry out an important function of internal secretion - the formation of germ cells occurs in them.
The effect of testosterone on the body
The influence of testosterone causes the development of the body according to the male type: the larynx has a special structure, the vocal cords thicken a little, the hairline is significantly developed.
In addition, testosterone promotes the growth and proper development of the prostate and appendages, male seminal vesicles, the development of body muscles, the formation of male libido, the growth and proper development of the external genital organs.
