From my perspective this is dangerous because an ossified pelvis cannot expand to accomodate a pregnancy.
If you want until she is an adult woman then her pelvic size is fixed and this endangers the baby if the head is too big for the ilium
If however you impregnate a young woman whose pelvis has not ossified, then the outward pressure of the fetus could expand the growth of the pelvis so that it is big enough for the fetus to inhabit.
This not only is safer for that current fetus but any future feti you put into her since you will have permanently expanded her pelvic width for optimal baby residence.
The ossification of the pelvic crest in females begins around 12-13 and the union of the ossification centres completes around 15-18 so it would seem this is the prime range for a first pregnancy.
supposedly studies show that there is less maternal mortality with moms age 20-24 than with moms age 15-19
I think this is misleading though since we don't take into account variables which could influence this outcome.
These are stats taken from a sedentary age where women are inactive and I think physical activity would increase cell turnover and biological adaptation, allowing things like pelvic shifting to tape place.
Also there are economic factors - the 20-24 is probably established/married whereas the 15-19 is not allowed to be married to a man and is unsupported (ie malnourished, stressed) during her pregnancy, by comparison.
If we allowed the 15-19 group to marry and encouraged physical activity I bet their mortality rate would be lower than the 20-24.
