Male genital tract

We need not here writing long-winded story about what a man’s genitals are and for what it is. In this article we will focus purely on anatomical detail and attractions that the male genital tract hiding.

The male reproductive system consists of external and internal organs. Some of these bodies are paired some are not. The entire unit is the indispensable system in reproductive function.

Management genital tract

  • hypothalamus, anterior pituitary through hormones, regulates the production of testosterone
  • testes produce the hormone testosterone
  • Sertoli cells direct spermatogenesis (formation of sperm)

Testosterone

  • ensures the development of the male genitalia type of fetus
  • after puberty causes the growth of external genital organs
  • development of secondary sexual characteristics (voice, body hair, building the skeleton)
  • stimulates the production of the hormone which regulates hematopoiesis (erythropoietin)

The external genital organs

  • Penis (penis) – coupling organ in the flaccid state measures 10 – 13 cm. Cock has three erectile bodies, two pair stored at the dorsal side and unpaired spongy body. Venous filling spaces occurs when the penile arousal (erection). Phallus is terminated ACORN, which protects the foreskin.
  • Scrotum (scrotum) – skin bag divided into two separate areas for right and left testicle.

Internal genital organs

  • Testis (testis) – paired gland 4-5 cm long, 2-3 cm wide. During fetal development, the testicles are located deep in the lumbar region, before the birth descend into the scrotum. Sperm fact require a lower temperature for maturation than the abdominal cavity. Testicle is protected by several layers of membranes. In the testes are also present Laydigovy cells that protect the sperm and produce testosterone.
  • Epididymis (epididymis) – deposited along the rear perimeter of the testicle. Here are collected sperm can stay here for up to 40 days.Epididymal combine to eventually result in the vas deferens.
  • Vas deferens (ductus defferens)
  • Měchýřkovité glands – secretions of these glands contains nourishment for sperm
  • The prostate gland (prostate) – looks like a chestnut, is located under the bladder, which abuts beginning of the urethra. Secretions from the prostate mixes with sperm and ejaculate arises. Rear side of the prostate facing the rectum, so when the DRE palpable.
  • Urethra (urethra masculine) – used to drain urine and to convey the sperm to the egg.

Spermatogenesis

  • The number of chromosomes in the sperm is half than other cells in the body – 22 somatic and sexual 1 (X or Y), which determines the sex of the child.
  • Mature sperm has three basic parts – a header (containing chromosomes), cervix (energy movement) and flagella (sperm movement).

The male sexual system is a very sophisticated system, where the slightest deviation leads to infertility, which in recent years has significantly increased. Sedentary jobs, tight clothes, unhealthy lifestyle (smoking, fatty foods, lack of exercise). Protect your reproductive system until it’s time, artificial insemination is not always possible and sperm cells of men with slow growing.
