Male testicles are often called testicles. They are an important component of the male body as a whole and the reproductive system in particular.
Body description
In the old days, when a man took 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 constitutes anatomy of the testicle. We will study this issue in this article.
The male testicles are a paired organ, and they are always isolated from each other. They are located in the scrotum cavity 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 into the appendages, after which they are released during ejaculation.
Interesting fact
The standard phenomenon for all men is some asymmetry of the testicles. This feature is not a deviation, and you should not worry about it. Asymmetry does not have any effect on male fertility. Scientists suggest that this feature is a protective reaction that helps to reduce the risk of simultaneously traumatizing both testicles. However, many men continue to worry about this, thinking that the asymmetry of the testicles affects their functioning.
Also quite often there are men worried about the fact that one testicle may have a size slightly larger than the other. Such experiences are groundless. Different testicle sizes are normal. The weight of the testicle can also be different - 25-50 grams.
What is a male testicle? What part does it take in spermatogenesis? What is the anatomy of the testicle?
So, the male testicles are paired gonads that produce the hormone testosterone, as well as germ cells - sperm.
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 tight underwear, abuses trips to saunas and baths, then this can cause infertility resulting from exposure to elevated temperatures. Some modern inventions can also say on men's health , for example, heated seats in a car. Therefore, do not abuse such comfort.
In the course of the study of the most important testicular functions, quite valuable data were obtained related to the treatment of infertility. Analysis of the composition of sperm allows you to identify a variety of reasons why men have infertility. Diagnosis carried out in a timely manner allows you to take appropriate measures during the treatment process.
Testicular anatomy
The anatomy of the male testicles is quite complex. This is due to the fact that they have an important purpose. Allocate the middle part in them, as well as the posterior, upper, lower end. Epididymis is adjacent to the posterior end of the testis.
As we have already noted, the testes are paired organs that have a flattened oval shape. Until the onset of full ripening of the man, the development of the testicles and appendages occurs very slowly, however, further there is a significant acceleration of their development.
The testicle is covered with a membrane, and partitions depart from it, dividing the testicle into special lobules. Each consists of 270 lobules. The anatomy of a man’s testicle is unique.
Functions of testicles and their structure
• Each of 270 lobules contains several seed canals. There can be one, two or three. Seed channels have a convoluted shape 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. In the mediastinum, the channel shape straightens, they pass into the testicular network, located in the plexus of the testicles. What else does male anatomy include?
• The channels of the testicular plexus have extension channels, of which 15 pieces. The efferent channels enter the epididymis (epididymis), thereby forming the head. Sperm cells acquire an exceptional ability to fertilize only after they pass through the appendage.
• Next, consider the anatomy of the epididymis. The canals then pass into the sperm-derived duct. The vas deferens is also part of the spermatic cord . This duct runs through the wide ducts into the groin to the bladder. The maximum convergence of the ducts with each other is observed in the area of the bladder.
• The duct that expels the seed (male testis) expands slightly at the end, forming a vas deferens. Its length reaches two centimeters. It passes through the prostate and a narrow hole opens on the tubercle of the urethra.
The testicle is 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. 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 low temperature on the surface of the scrotum and inside the testicles is possible, thanks to two main mechanisms:
1. The scrotum has very thin skin.
2. The presence of a specific vascular plexus, due to the fact that the arteries located between the lobes of the testicles are densely braided by veins.
The cell structure of the male testis
About 14% of the total volume is mast interstitial tissue, which, in turn, consists of Leydig cells, mast cell connections, connective tissue, capillaries, macrophage fragments.
About 70% of the male testes consist of seminal channels formed by three types of somatic cells, such as Sertoli cells, puritubular cells, and spermatogenesis cells.
The testicle is always covered with a protein coat and spliced with it. It is located in the parietal and visceral sheets. In tandem, they form a membrane that is associated with muscle bundles. These bundles very effectively support the testes, which avoids unnecessary tremors.
The protein shell has a specific thickened structure and is located near the posterior edge of the testicle. Partitions depart from the thickening, which form the connective tissue and divide the male testicle into 270 lobules.
The human testicle anatomy 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 in size.
Quite often, men worry about the location and size of their testicles. If the difference in size is not more than a centimeter, and at the same time the man does not experience any uncomfortable sensations, then there are no reasons for experiencing. 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 examined in detail. 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 bloodstream directly from this paired organ.
The testes also perform 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 determines the development of the body according to the male type: the larynx has a special structure, the vocal cords are slightly thickened, and 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 musculature of the body, the formation of male libido, the growth and proper development of external genital organs.
