"WitrynaSpermatogenesis is a continuous process during adult life and, thus, the adult testes contain all stages from stem cells to mature sperm (Figure 1).

WitrynaOogenesis. Spermatogenesis is the process of the origin and development of the male gametes. Oogenesis is the process of the origin and development of the female gametes i.e. the egg cells or the ova, inside the female reproductive organ, namely the ovary. The gametes produced are motile. The gametes produced are non-motile. WitrynaOogenesis, illustrated in Figure 24.13, occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to about one to two million cells in the embryo. Figure 24.13.
