Oogenesis picture
WebOogenesis is the creation of an egg (also known as an ovum or oocyte) in the female foetus. Oogenesis starts in the foetus at around 7 weeks' gestation, when primordial germ cells colonize the newly formed ovary. They are now referred to as oogonia.16. Oogonia undergo mitosis or rapid proliferation (multiplication). Weboogenesis, in the human female reproductive system, growth process in which the primary egg cell (or ovum) becomes a mature ovum.
