Oogonia multiply until the fifth month .within six months after birth ,each will transform into a primary oocyte .
What is oogonia ?
During foetal stag of development the embryo develops the germinal epithelium of ovary .some of the cells of germinal epithelium enlarge and divide mitotically . the dividing cells projects into the stroma as a cord known as the egg tube of Pflugar;which later becomes a round mass ,called the egg nest .all these dividing cells are egg mother cells known as Oogonia.this is derived from the endodermal lining of the embryonic yolk sac which comes to lie in the ovary of the female ( while it is still an embryo ).
What is primary oocyte?
One cell of the egg nest grows but does not divide furter so as to form the primary oocyte.the primary oocyte is diploid and enters the growth phase.it is dormant stage ,nucleus intact ,female is born with these in her ovary.every month primary oocytes resume oogenesis and start developing growth and development in the onset of puberty.
