MICROANATOMY

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: -At birth, there are approximately 1 million eggs left. By the time you reach puberty, only about 300, 000 remain. The number of eggs you have continues to decline as you age and menstruate each cycle. Fertility also declines with age due to the decreasing number and quality of your remaining eggs.

Detailed explanation-3: -A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle. Pregnancy happens if a man’s sperm meet and fertilise the egg. Sperm can survive in the fallopian tubes for up to 7 days after sex.

Detailed explanation-4: -When you are born, this number has reduced to around two million and by the time you reach puberty and begin menstruation (start your periods) you will have somewhere between 300, 000 and 500, 000 eggs remaining. At menopause, you will have 1, 000 to 2, 000 eggs remaining.
