WebOogenesis. Oogensis is a type of gametogenesis. It is the production of an ovum or egg cell and occurs in all sexually reproductive species. Oogenesis involves the creation of haploid sex cells through the process of meiosis. Female germ cells undergo extensive mitotic division in the foetal ovary. The creation of oogonia. The creation of oogonia traditionally doesn't belong to oogenesis proper, but, instead, to the common process of gametogenesis, which, in the female human, begins with the processes of folliculogenesis, oocytogenesis, and ootidogenesis.
