At birth the testis of a biological male does not contain sperm, but contains immature stem cells which can produce sperm after puberty. Once puberty starts, signals from the pituitary gland tell the testes to start producing the hormone testosterone and the testes start to increase in size. From about mid-puberty onwards, the germ cells in the testes become mature enough to start producing sperm. In the mature testes, the Sertoli cells are responsible for making sperm and the Leydig cells are responsible for producing testosterone.
