The primitive stem cell of spermatogenesis found on the periphery of each seminiferous tubule is called spermatogonia. Spermatogonia is an undifferentiated male germ cell.
These cells include skin cells, blood cells, and any cell other than sex cells. Meiosis is the process that creates sex cells. These cells include sperm and egg cells. Seminiferous tubules are structures located in the male reproductive gland known as the testis. Meiosis in males occurs in the seminiferous tubules. This means that the seminiferous tubules are crucial in the process of reproduction. The seminiferous tubules consist of a network of tubes that are lined with a type of cell known as a sertoli cells. Sertoli cells are long columnar cells that are differentiated during the process of meiosis to form sperm.
