And so we'll see four of these sperm cells produced at the end because these spermatids, with the help of these nourishing cells known as sirtoli cells, showed in green, eventually differentiate into our sperm. Cell. So these spermatids, when they interact with the surtoli cells the surtoli cells not only give the cells the proper nutrients but the surtole cells also faggot phagocytes. They remove the cytoplasm from our spermatid to produce the sperm cell. And we'll discuss what the structure is of the sperm cell in just a moment. Once the sperm cells are actually formed they are released into the lumen, the cavity of the seminar's tubule.
