Detailed explanation-1: -Current knowledge indicates that females are born with their entire lifetime supply of gametes. At birth, the normal female ovary contains about 1-2 million/oocytes (eggs). Females are not capable of making new eggs, and in fact, there is a continuous decline in the total number of eggs each month.
Detailed explanation-2: -“There’s just a natural death of them.” For all the eggs a woman begins with, in the end only about 400 will go through ovulation. While men produce sperm throughout their lives, over time the number of eggs declines, and they disappear with increasing frequency the decade or so before menopause.
Detailed explanation-3: -Unlike men, whose reproductive organs produce millions of fresh sperm on a daily basis, women are born with all the eggs that they will ever possess. Moreover, this number steadily declines as a woman ages: from one million eggs at birth to 300, 000 by puberty, 25, 000 by the age of 37 and 1, 000 by the age of 51.
