Vedclass · Answer

(B) During fetal development,millions of oogonia are formed within each fetal ovary. No more oogonia are formed or added after birth. These oogonia start division and enter into prophase-$I$ of the meiotic division and get temporarily arrested at that stage,called primary oocytes. Each primary oocyte then gets surrounded by layers of granulosa cells and is called the primary follicle. $A$ large number of these follicles degenerate during the phase from birth to puberty. Therefore,at puberty,only $60,000-80,000$ primary follicles are left in each ovary.
