Physiological Factor of sexuality of Men and Women

The anatomical and physiological provision of the genital area, along with the genital organs, involves various departments of the peripheral and central nervous system, as well as many departments of the endocrine apparatus.

The reproductive organs of a MAN (genitals) are divided into
sex glands (testes);
genital tract (semen ducts);
additional education (adnexal sex glands);
Copulatory organs (penis).

In practice, the male genital organs are divided into external and internal. The internal ones include the testicles, their appendages, seminal vesicles, the vas deferens, the prostate gland, and the external ones include the penis and scrotum.
Testicles (testicles, testicles) - a pair of male gonads. Anatomically, the testicle is an oval, somewhat flattened body along the medial surface, which in an adult has a size of 4-4.5x2.5-3.5 cm and a weight of 20-30 g. A few weeks before birth, the testicles are displaced through the inguinal canal into the scrotum - an important pouch formation. The testicles are suspended in the scrotum with the help of cremaster muscles, which in the cold raise the testicles closer to the body and protect them from hypothermia, and in high temperatures they relax, and the testicles fall lower, which reduces the temperature. One of the testicles usually sags a little lower than the other, but this is not of fundamental importance.
