Explanation:
Detailed explanation-1: -Many of the primary oocytes degenerate before birth, but even with this decline, the two ovaries together contain approximately 700, 000 oocytes at birth. This is the lifetime supply, and no more will develop.
Detailed explanation-2: -Of the millions of primary oocytes present at birth, only about 400 mature during a woman’s lifetime.
Detailed explanation-3: -Many of those eggs will be lost before puberty sets in through a natural process called ovarian follicle atresia, leaving a woman with around 300, 000 eggs at the time of puberty. Of those, it is estimated that a woman may lose as many as a thousand eggs per month over her fertile years.
