Vedclass · Answer

(D) 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 gets surrounded by a layer 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.
