sperm is male reproductive cell , matured sex cells which carriers genetic information from male .
The male reproductive system in man consists of primary sex organs,the testes,and a set of accessory sexual structures.Each of two testes in the adult male is an ovoid body.Both are located outside the body cavity within a skin covered pouch called the scrotum.The two principal functions of the testes are the formation of sperm cells by spermatogenesis and the production of male sex hormone,testosterone. The reproductive system of human female consists of two female gonads(the ovaries) which produce female gametes or egg cells,and associated ducts and structures.
