MICROANATOMY

Detailed explanation-1: -The production of these vital reproductive cells occurs in the testis and ovary during the processes of spermatogenesis and oogenesis, respectively. [1] The primary male reproductive organs, the testes, are located inside the scrotum and function to produce sperm cells as well as the primary male hormone, testosterone.

Detailed explanation-2: -Testes Produce Spermatozoa. Spermatozoa are produced within structures called the seminiferous tubules. These tubules contain stem cells called spermatogonia (singular is spermatogonium) that derive from primordial germ cells that enter the testis during embryogenesis.
