Oogonia enter into meiosis and are arrested in prophase of first meiotic division to form primary oocyte by 20weeks in fetal life These primary oocytes do not enter metaphase, but rest in diplotene stage of prophase until pubey This is due to the secretion of oocyte maturation inhibitor by follicular cells.
