The testicles.. Place of male sperm production and production of male hormone (testosterone) responsible for secondary male reproductive traits



The testicles are the spines and contain a number of lobes. Each lobe contains very fine anibles known as spermiculi and are up to a few hundred meters in each testicle. These tubules are the place where male sperm are formed. The testes are also produced by the male hormone testosterone, which is produced from the interstitial cells that are spread in the testicular tissue. This hormone is responsible for secondary male reproductive traits such as coarseness, muscle density in men and hair growth in certain areas of men. It also contributes to the maturation and growth of sperm (sperm ) Within the testicle (spermatozoa). The external testicles are surrounded by a membrane known as the scrotum. Sometimes the testicles remain in some children inside the cavity of the body and do not descend into the scrotum, which may lead to infertility later if not treated. It is believed that the internal temperature of the body (37.5 m) is not suitable for the formation of sperm in the testis while inside the cavity of the body, but in the scrotum, the temperature is suitable for composition as the temperature up to about 35 m so you must see your doctor to work on the testis Hanging in the scrotum to be lowered.
