The structure of the penis and other organs of the male reproductive system

Male genitalia conditionally divided into two categories - external and internal. The external genitalia are represented by the penis and scrotum, and the internal ones by the testes, appendages of the testicles, the prostate gland and seminal vesicles. All the work of the male reproductive system is aimed at producing quality sperm for the continuation of the genus - so nature is arranged. In some cases, the functions of organs can be violated, because of which the reproductive function suffers - there is a so-called male infertility.

The male penis is the organ that takes the sperm and urine out. In anatomy, the structure of the penis is divided into parts such as the head, trunk and base. The trunk consists of cavernous and spongy bodies containing pores. During sexual arousal, blood flows to the genitals and fills these pores.

The end of the penis is represented by the head. The structure of the male genital organ, especially the fact that the greatest number of erogenous points is located exactly on the head. The second zone in the erogenous zone is the lower part of the trunk of the penis. When exposed to these zones, there is an erection and, as a consequence, orgasm. At the end the head is covered by the foreskin, and under it are the special glands that give off the smegma - a substance serving as a lubricant to ensure a normal opening of the head. For representatives of the male it is very important to monitor the cleanliness in the zone of the foreskin, so as not to become a victim of inflammatory diseases.

The structure of the penis is such that when the blood rushes during excitation, the organ significantly increases in size, thickens and thickens noticeably. The structure of the male genitalia is arranged in close contact with the urinary ducts. However, nature is prudent, and during sexual intercourse, due to an increase in the size of the seed tubercle, the urine is prevented from reaching the outside, so it does not mix with such valuable genetic material as sperm. When the necessary amount of frictions is reached, orgasm sets in and sperm is output through the head opening, the formation of which is quite difficult and depends on many conditions. First, in a condensed form, sperm from the testicles are sent to the prostate gland, where it is diluted with a special liquid. With rhythmic movements during intercourse the work of the muscles of the perineum, abdominal press and directly of the prostate is activated. It is this complex coordinated work that allows you to push the sperm into the vagina with the necessary force so that it can reach the goal as soon as possible.

The structure of the penis and its functions are clear. Now consider the structure of the rest, no less important bodies. The scrotum is an organ that includes both the skin and the muscles, which serves as a receptacle for the testicles, appendages and part of the spermatic cord. Usually the skin of the scrotum is somewhat darker than the skin of the penis itself, it is covered with hair and has a sufficient number 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 testes represent the internal genitalia. In them, the formation of spermatozoa - the most valuable material in the field of reproducing themselves. Testicles also supply testosterone, which answers as a whole for the genital area of a man, they are placed on opposite sides of the penis and often have a different size, but this is not a pathology, but rather individual characteristics of the organism. The testicle is supplied with blood by means of the spermatic cord, which also takes the sperm to the vas deferens. Already from the vagina semen is excreted from the body.

A special role in the male sexual sphere is played by the prostate. This gland is located at the level of the rectum and just below the bladder. Complete development of the prostate reaches the time of puberty boys - about seventeen years. The main function of the prostate is to make the sperm more fluid and thus promote the promotion of spermatozoa in this environment. The quality of this secretion is greatly influenced by the ability of spermatozoa to actively move and fertilize. In order for spermatozoa in the vaginal environment to be more enduring, they receive a kind of recharge 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 of the mother. However, the growth of the penis continues to about 16-17 years.
