It's hard to compete with 20 billion years of evolutionary selection, but the current medical management of the birth of the fetus and the placenta attempts to do just that, albeit rather unsuccessfully. For eons, all animals including humans passed on genes and habits that ensured delivering a live healthy newborn without bleeding excessively or dying of postpartum hemorrhage at birth.
Whether she is aware of it or not, the woman decides when, where and how to give birth. Our bodies are under our control whether we have accessed the keys to that control or not. Extreme control has been demonstrated by highly trained martial arts experts who can prevent themselves from ovulating.
