Spermatogenesis
[Gr. spermatos - seed, semen; Gr. genesis - origin, descent].The process in males whereby mature spermatozoa are formed from spermatocytes.

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 occurs in seminiferous tubules in testes.
The cell that undergoes meiosis is a primary spermatocyte.

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.

This is due to the fact that spermatogenesis in mammals is more efficient at a temperature somewhat less than the core body temperature (37°C or 98.6°F for humans). The cremasteric muscle is part of the spermatic cord.

stack of intracellular membrane compartments (organelle) that function to modify and package secreted and integral membrane proteins; during spermatogenesis, the golgi apparatus causes the formation of an acrosomal vesicle in the sperm head.

Two genes positioned near one another on a chromosome may encode proteins that figure in the same cellular process or in completely unrelated processes. As an example of the former, many of the genes involved in spermatogenesis reside together on ...
