A male’s ability to reproduce depends on a high quality and quantity of sperm; therefore, spermatogenesis occurs continually from the time of puberty until death. The average man produces more than 1,000 sperm cells every single second and they need around nine to ten weeks for their full development and maturation. Spermatogenesis is the process of formation of mature sperm cells through a series of mitotic and meiotic divisions along with metamorphic changes in the immature sperm cell.. Cells produced by the first few divisions of the fertilized egg are also totipotent. So are the cells that divide to produce gametes, called gametocytes, the cells that produce those, called gametogonia, and all the way back to the zygote, the cell from which an individual develops. The cell cytoplasm spans all layers of the seminiferous tubule. Sperm motility refers to the movement and swimming of sperm. Anatomy.
