Child bearing
These days you see professionally successful woman are having babies in their forties after they have achieved the pinnacle of their career. Women lose their natural ability to conceive with age. Egg formation process called oogenesis begins before a girl is born during the prenatal development of the ovaries. In the Embryonic Ovaries the number of eggs cells are determined. Biologically speaking at birth a girl baby is born with two million eggs. During puberty only 3-400,000 eggs remained alive. In case of male, sperm production is continuous since the diploid mother cells that give rise to primary spermatocytes continue mitosis through out life. However sperm count become lower with age in man. Sperms are freshly generated by spermatogenesis compared to the egg which started the process before birth and set the number at early stage of meiotic cell division. Set numbers of eggs during prenatal development in girls continue to die and get aged with the passing of time.
A 38 years old women ovulating an egg is 38 years old which began Meiosis 37 years ago. During that period of time the egg was exposed to different conditions of the body. As a result there are chances of DNA damage to aged eggs. The increased risk of birth defects in older mother may be related to the aged eggs.
