Sperm Production

Male Genital Tract:

Men produce sperm from germ cells within the testes throughout adult life. The production is controlled by various hormones, including FSH and LH (see illustration below). LH stimulates the specialized Leydig cells in the testes to secrete the male hormone testosterone. FSH, in conjunction with testosterone, stimulates the seminiferous tubules in the testes to produce mature sperm (see illustration below). Completion of the entire process of sperm production (spermatogenesis) takes about 72 days.

Sperm are highly specialized cells, which comprise two essential parts: the head, formed by the acrosome, and the tail, which enables the movement. The acrosome surrounds the nucleus where genetic information is stored (see illustration below).

Sperm Cell

The production of sperm is, however, an inefficient and vulnerable process and for the daily production of several hundred million mature sperm, more than eight times as many germ cells are required. Furthermore, only a fraction of the sperm produced will have fertilizing potential
