I would think that there'd be a threshold where the elevated risk of birth defects would place a ceiling on how old parents should be.
25-35 seems to be the ideal window, where the parents have had ample opportunity to get to know themselves as individuals, and the risks of a severe disability aren't particularly elevated. Afterwards, the risk seems to climb very quickly.
