Spermatogenesis is the process by which male spermatogonia develop into mature spermatozoa. Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis.
Spermatogenesis refers to the creation, or genesis, of sperm cells, which occurs in the male gonads or testes. Sperm cells develop initially from germ stem cells known as spermatogonia .

Spermatogenesis
Sperm production begins at puberty at continues throughout life, with several hundred million sperm being produced each day. Once sperm form they move into the epididymis, where they mature and are stored.

spermatogonium Precursor of mature male reproductive cell; gives rise directly to a spermatocyte.
In the ovary it is referred to as oögenesis and in the testes as spermatogenesis. Meiosis produces the gametes called eggs (ovum, sing., ova, plural) and sperm. It involves two cell divisions and therefore four cells result from each meiotic event.
