Male intimate anatomy. The structure of the male reproductive system

The male anatomy is definitely different from the female anatomy. The most characteristic differences relate primarily to the structure of the genital organs. The anatomy of the male genital organs is divided into internal and external organs. Outside are the penis and scrotum. The scrotum protects the testicles that produce sperm. Male fertility largely depends on the functioning of the testicles. The internal genital organs include the epididymis, vas deferens, seminal vesicles and glands - the prostate (i.e. prostate or prostate) and bulbourethral glands.

1. Male external genitalia

genital anatomy ensures the performance of the main functions of the male reproductive system, namely: spermatogenesis, i.e. the process of sperm formation and transport of sperm into the female genital tract. Male reproductive organs they are divided into internal and external.

1.1. Penis

It is a copulatory organ, at the top of the penis there is a head very sensitive to irritants, covered with a skin fold, that is, the foreskin; the penis consists of two tissues that swell with blood during the act of making, increasing its volume and length; the penis has a urethral fragment (urethral opening) through which urine or semen exits. Therefore, the penis combines the functions of the male reproductive system and the urinary system.

1.2. Purse

This is a skin pouch located in the vulva. The testicles are in the scrotum. The scrotum protects the testicles and maintains their optimal temperature.

2. Male internal genital organs

2.1. testicles

The testicles are located in the scrotum, in a folded skin sac; inside the testicles there are seminiferous tubules responsible for the transport of spermatozoa, and interstitial glands that produce hormones (including testosterone), so the testicles are the most important organs for the proper functioning of two systems: reproductive and endocrine; the left testicle is usually larger and lower suspended, highly sensitive to injury and temperature changes,

2.2. epididymides

Epididymides are adjacent to the testes along their anterior course. Epididymides are tubules that form a duct several meters long, in which there are cilia responsible for the movement of spermatozoa. It is filled with sperm storage until they reach full maturity. Epididymides are responsible for the production of acidic secretion, which contributes to the maturation of spermatozoa.

2.3. vas deferens

On the other hand, the vas deferens is the duct that carries sperm from the epididymis through the scrotum to the inguinal canal and into the abdominal cavity. From there, the vas deferens pass into the pelvis and behind the bladder enter the prostate canal, where they connect with the duct of the seminal vesicle and form the ejaculatory duct.

2.4. vesicospermenal gland

It is located near the bottom of the bladder and is used to produce substances that provide energy for sperm. It is a source of fructose, which nourishes the sperm. In addition, the liquid contains ingredients that cause uterine contractions, which increases a woman's chances of fertilization.

2.5. Prostate

The prostate gland is also known as the prostate gland or the prostate gland. It is a chestnut-sized gland surrounding the urethra, consisting of right and left lobes, which are connected by a knot; the gland is surrounded by smooth muscles, the contraction of which transports the sperm out; Under the prostate are the bulbourethral glands.

2.6. bulbourethral glands

The bulbourethral glands are responsible for the release of pre-ejaculate, i.e. a secret that protects sperm from the acidic environment of the urethra and vagina.

This fluid contains a small amount of spermatozoa, but this amount is still enough for fertilization.
