Naturally a woman is born with the fixed number of eggs she will need during her reproductive years (12- 45 years). By birth she usually has about 500,000 to 700,000 immature eggs. She loses about half of this naturally, by the time she gets her first period and be-comes biologically fertile. There after she will continue to remove about ten eggs every month but with only one or two maturing to be released for possible fertilization and hence pregnancy. If no fertilization occurs these eggs are lost in the month and she then gets her period (menstruation),the cycle continues over and over again.
The best quality of eggs are usually produced within the ages of 20 to 35 years. There after the quality of the eggs reduce and (POI). In many of these women the cause of the POI/POF/PMP some cycles may even occur with-out the woman releasing any eggs. By the age of 50 a woman usually reaches menopause and the eggs practically get finished. However, it has been found out that actually the ovaries can be rejuvenated to pro-duce some more young eggs cells that have been redundant since birth, thus awakening up the egg and hormone production.
In some other women, the ovaries may stop producing eggs and hormones at a younger age (less than 40 years), a condition called premature menopause (PMM) or premature ovarian failure (POF)How do the eggs of a woman form? The life Cycle of a woman’s egg may not be known .
