MICROANATOMY

Detailed explanation-1: -Newborn girls have about 1-2 million eggs, but normal ovaries until puberty only have about 300, 000 eggs. Of these, only about 500 will be released during a woman’s reproductive years.

Detailed explanation-2: -How many eggs do women have in their 30s? There is no one right answer to this question, as certain factors – such as smoking or other personal factors – may mean a woman has fewer eggs than others. The average number of oocytes at the age of 30 would be around 72, 000 (12% of maximum pre-birth levels).

Detailed explanation-3: -A woman’s biological clock 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.

Detailed explanation-4: -By puberty, a woman’s egg count might be 1 million; at 25, maybe 300, 000. Then, around 35, the decline starts to get a bit steeper until all eggs have been depleted (menopause).
