Definition of Spermatogenesis
Spermatogenesis is a process through which the male gametes are produced. These sperm cells are produced inside the male reproductive organ known as testis which is composed of a large number of thin tightly coiled tubes called seminiferous tubules.
The walls of these tubules are constituted of the scattered cells which are termed as sertoli cells. The sertoli cells serve the purpose of providing support and nourishment to the immature sperm cells. The testes have the tendency to continuously produce sperm cells. It takes an immature sperm cell about 70 days to reach the final maturation stage.
