Sertoli 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.Remember that the sertoli cells are also known as nurse cells.
