Card 6 / 39:
Discuss spermatogenesis with respect to the timing of the process, and the number and types of cells finally produced.
Stem cells are laid down in the male during gestation and lie dormant until adolescence/puberty. At this time, spermatogenesis begins and continues until death, producing the maximum number of sperm (i.e. four per cell that started meiosis) with each meiotic division. The process takes approximately 70 days and the sperm are released into the lumen of the seminiferous tubules.
