The basic definition is: Spermatogonia are are the first cells of spermatogenesis. They originate in the 4th week of foetal development in the endodermal walls of the yolk sac and migrate to the primordium of the testis, where they differentiate into spermatogonia. Spermatogonia remain dormant until puberty.

The primitive stem cell of spermatogenesis found on the periphery of each seminiferous tubule is called spermatogonia. Spermatogonia is an undifferentiated male germ cell.
The spermatogonia are the cells that initiate spermatozoa
