How age affects fertility

Age affects fertility drastically in women and less so in men. Women are born with all the eggs they are going to have in their lifetime stored in their ovaries at birth, and they start utilizing those eggs from birth until they go through menopause, which is just when their ovaries have run out of eggs for ovulation. The egg cell is as old as a woman, and therefore when a woman's twenty, her eggs are relatively young and they function very well. In her thirties, they are still fairly young and functioning well as far as fertility output. When women get into their forties, early forties, mid forties, late forties, the egg function declines dramatically. The chances of fertility decrease dramatically from about age thirty-nine on. So it's key for a woman who's concerned about having a family to either begin that family if she can in her early thirties, or certainly by her late thirties. If she gets closer to forty, the odds of her being pregnant and successful having a child get lower and lower. The male doesn't get affected the same way. Time and age don't affect the male, but men of older age have certain risks. Not fertility risks, but they have risks of having abnormalities in the children that they father in their sixties, seventies, and eighties.
