Spermatogenesis - Wikipedia
WebSpermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testicle. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. [1] . These cells are called spermatogonial stem cells.
