In males, this process is called spermatogenesis … WebOogenesis in mammals: In mammals the process of oogenesis shows the following three phases: 1. Phase of multiplication: The primordial germ cells become the oogonia—the egg mother cell. The oogonial cells eventually undergo proliferation by repeated mitotic divisions, giving rise to the eggs and become primary oocytes when cell division ceases.
