Male genitals are conventionally divided into two categories - external and internal. The external genitalia are represented by the penis and scrotum, and the internal ones are the testes, epididymis, prostate gland and seminal vesicles. All the work of the male reproductive system is aimed at producing high-quality sperm for procreation - this is how nature works. In some cases, the functions of the organs may be impaired, due to which the reproductive function suffers - so-called male infertility occurs .
The male penis is an organ that removes sperm and urine. In anatomy, the structure of the penis is divided into such parts - the head, trunk and base. The trunk consists of cavernous and spongy bodies containing pores. During sexual arousal, blood rushes to the genitals and fills these pores.
The termination of the penis is represented by the head. The structure of the male genital organ is especially due to the fact that the largest number of erogenous points is located on the head. The second erogenous zone is the lower part of the trunk of the penis. When exposed to these zones, an erection occurs and, as a result, an orgasm. At the end, the head is covered with foreskin, and under it there are special glands that secrete smegma - a substance that serves as a lubricant to ensure normal opening of the head. For males, it is very important to monitor cleanliness in the foreskin so as not to become a victim of inflammatory diseases.
The structure of the penis is such that with a rush of blood during arousal, the organ increases significantly in size, becomes denser and visibly thickens. The structure of the male genital organs is arranged in close contact with the urinary ducts. However, nature is prudent, and during intercourse due to an increase in the size of the seed tubercle, urine is prevented from exiting, so it does not mix with such valuable genetic material as sperm. Upon reaching the required number of frictions, an orgasm occurs and sperm is excreted through the opening of the head, the formation of which is quite difficult and depends on many conditions. First, in condensed form, sperm from the testes is sent to the prostate gland, where it is diluted with a special fluid. With rhythmic movements during intercourse, the work of the muscles of the perineum, the abdominals and the prostate itself is activated. It is this complex, coordinated work that allows you to push sperm into the vagina with the necessary strength so that it reaches the goal as quickly as possible.
The structure of the penis and its functions are clear. Now consider the structure of the remaining, no less important organs. The scrotum is an organ that includes both skin and muscles, which serves as a container for the testicles, appendages and part of the spermatic cord. Usually the skin of the scrotum is slightly darker than the skin of the penis itself, it is covered with hair and has a sufficient amount of sweat glands. All this is necessary to ensure the constancy of the temperature environment inside the scrotum itself, because it is slightly lower than the total body temperature - about thirty-four degrees, although the internal temperature in the body is about thirty-seven.
The testicles represent the internal genital organs. In them, the formation of sperm cells - the most valuable material in the reproduction of their own kind - takes place. The testicles also supply testosterone, which is generally responsible for the male’s sexual sphere, they are located on opposite sides of the penis and often have an uneven size, but this is not a pathology, but rather individual characteristics of the body. The testicle is supplied with blood through the spermatic cord, which also removes sperm to the vas deferens. Already from the vas deferens sperm is excreted from the body.
A special role in the male genital area is played by the prostate. This gland is located at the level of the rectum and slightly lower than the bladder. The prostate reaches full development by the time of puberty in boys - by about seventeen years. The main function of the prostate is to make sperm more fluid and thus contribute to the promotion of sperm in this environment. The quality of this secret is significantly affected by the ability of sperm to actively move and fertilize. In order for sperm in the vaginal environment to be more resilient, they get a kind of nourishment from the seminal vesicles.
The structure of the genital organs of men in general and the structure of the penis in particular is laid in the womb. However, penile growth continues until approximately 16-17 years.
