Detailed explanation-1: -By the time a girl enters puberty, only about 25% of her lifetime total egg pool remains, around 300, 000. Over the next 30-40 years of a female’s reproductive life, the entire egg supply will be depleted.
Detailed explanation-2: -The number of eggs decreases as women get older. At birth, most girls have about 2 million eggs, at adolescence that number has gone down to about 400, 000, at age 37 there remain about 25, 000. By age 51 when women have their menopause they have about 1000 immature eggs but these are not fertile.
Detailed explanation-3: -Over the course of a lifetime your ovaries will release about 500 eggs in their mature form. When the supply of eggs runs out, your ovaries cease to make estrogen, and you will go through the menopause.
