It is located in the pelvic region.
It consists of:
A pair of testes
Accessory glands and ducts
External genitalia
Testes
Situated within the scrotum, which protects the testes and also helps in maintaining the temperature.
Each testis is 4 to 5 cm in length, and 2 to 3 cm in width, and has about 250 compartments called testicular lobules.
Testicular lobules have seminiferous tubules which are the sites of sperm formation.
Seminiferous tubules are lined by two types of cells:
Male germ cells − They undergo meiosis to form sperms.
Sertoli cells − They provide nourishment to the germ cells.
Region outside the seminiferous tubules is called the interstitial space, which contains Leydig cells (interstitial cells).
The Leydig cells produce androgens.
