The penis

The penis is the genital organ characteristic of man. It is crossed by a canal, the urethra, which serves both to pass urine and semen.

The glans is covered by skin: foreskin. During erection, this skin is back and the glans is uncovered. The foreskin is attached to the glans by a membrane called the brake.

The testes: sperm factory

The testes are the site of sperm production. They are two in number, contained in a sac called the scrotum, which can be abbreviated.

They are shaped like eggs by 2.5 inches wide by 3.5 cm long on average. If the testicles are located outside the body because they must be at a temperature slightly below 37 degrees, to produce sperm. They are also responsible for the secretion of a hormone: testosterone. She is behind the development of secondary male sexual characteristics (hair, muscles ...).
