The Sperm and Egg

Testes are suspended outside the abdominal cavity by the scrotum, a pouch of skin that keeps the testes close or far from the body at an optimal temperature for sperm development. Somniferous tubules are inside each testis, and are where sperm are produced by meiosis. About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn develop into mature sperm.

Sperm production takes place in the testes. The testes are in the scrotum. The scrotum is a sac located outside of the male's body. Since sperm can develop only in an environment with a temperature that is about 3°C lower than normal body temperature, the exterior position of the scrotum provides an ideal location.

Located within each testis, a fine network of highly coiled tubes are the production facilities for sperm. Sperm are produced through the meiosis of cells lining these tubes.......
