WebOogenesis is the process by which mature female gametes, or ova, develop from germ cells. The image below summarizes how this happens, and over what timeline it unfolds. In mammals, the first part of oogenesis starts in the germinal epithelium, which gives rise to the development of ovarian follicles, the functional unit of the ovary. Oogenesis consists of several sub-processes: oocytogenesis, ootidogenesis, and finally maturation to form an ovum (oogenesis proper). … Ver mais Oogenesis, ovogenesis, or oögenesis /ˌoʊ.əˈdʒɛnɪsɪs/ is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized.
