Male genitalia are conditionally divided into twocategories - external and internal. The external genitals are represented by the penis and scrotum, and the internal ones by the testicles, 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.
Male penis - the organ that derivessperm 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, an orgasm. At the end, the head is covered with the foreskin, and under it are the special glands that give off the smugma, 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 risesthe time of excitation the organ significantly increases in size, is compacted and visibly thickened. 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 spermatic 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 emitted 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, the abdominal press and directly 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 reaches its 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 organs. 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. They are the formation of spermatozoa - the most valuable material in the field of reproduction of their own kind. The testicles also supply testosterone, which is responsible for the genital area of the male as a whole, they are located 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 byprostate. 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 durable, 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.
