Class 12 NEET Biology Human Reproduction Questions Part 2

Option (2) is the correct answer as oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells (oogonia) are formed within each foetal ovary.
No more oogonia are formed and added after birth in a human female.
At puberty only 60,000 to 80,000 primary follicles are left in each ovary, rest degenerate during the phase from birth to puberty.
