the youngest human to ever bear children successfully was a 5 year old mexican girl, true story. the oldest human to ever bear children was a 73 year old woman in india via in-vitro fertilization. in both cases the child was delivered via caesarean section. so... if we're going to use the "old enough to breed" argument, you should find every woman between the ages of 5 and 73 desirable for procreation.
