In brief: Older women

It is observed that women have the lowest predicted rate of down syndrome births at ~20 (1/1925) with a gradual risewith age.
By 40 the risk reaches 1/110, 50 =1/10.Most speculate that the additive effect of lifes toxic exposures eventually add up to deminish the chances an egg can produce a normal infant.
