The primitive stem cell of spermatogenesis found on the periphery of each seminiferous tubule is called spermatogonia. Spermatogonia is an undifferentiated male germ cell.
However, sertoli cells are present in the seminiferous tubule. Where do the sperm cells mature? A textbook says they mature in the epididymis. However, sertoli cells are present in the seminiferous tubule, which nourish the developing the sperm cells until they are mature. Sertoli cells are present in the seminiferous tubule, not the epididymis. Hoertoli cells and spermatogenic cells help create and nourish the newly forming sperm. These immature sperm leave the seminiferous tubule as spermatozoa and enter the epididymis. Here the spermatozoa grow a tail, finish maturing, and are stored until ejaculation.
