Web26 de abr. de 2024 · Oogenesis is the female version of gametogenesis. It is the process of formation of female gamete or ovum, necessary for sexual reproduction. The process of oogenesis starts pre-natally, i.e. before the birth of the female child. It begins about 8-20 weeks after the fetus has begun to grow and goes on until the birth of the child.
