Spermatogenesis is the process by which spermatozoa are produced from spermatogonial stem cells. It can be divided into three main stages:
1. Spermatocytogenesis: This is the mitotic division of spermatogonia into primary spermatocytes. 2. Meiosis: Primary spermatocytes undergo two rounds of meiotic division to form haploid spermatids. 3. Spermiogenesis: This is the final stage where spermatids differentiate into mature spermatozoa. This involves the formation of the acrosome, condensation of nuclear material, and development of the flagellum.
