Spermatogenesis starts in the bottom part of seminiferous tubes and, progressively, cells go deeper into tubes and moving along it until mature spermatozoa reaches the lumen, where mature spermatozoa are deposited.

Where does spermatogenesis occur?

Spermatogenesis is a complex, strictly regulated process that takes place inside the seminiferous tubules of the testis. The process includes the proliferation of male germ cells, meiosis, and finally the haploid differentiation, which is characterized by dramatic morphological changes.

What is the first stage of spermatogenesis?

Spermatogenesis and Spermiation

The first phase is referred to as spermatogonial proliferation and renewal. During this period, relatively undifferentiated diploid spermatogonia, the immature germ cells, undergo several mitotic divisions to generate a large population of cells called primary spermatocytes.
