A study out of Cambridge University is shining light on the role the placenta plays in “ensur[ing] optimal health for both the mother and the fetus,” writes Dr. Fazale Rana of Reasons To Believe. Rana describes a “potential tug of war” that could theoretically happen between the mother and her preborn baby when it comes to the need for nutrients. But in reality, this doesn’t happen — thanks to the regulatory effects of the placenta. The placenta develops from cells belonging to the developing preborn child (blastocyst) after implanting into the wall of the uterus (between 5 and 8 days after fertilization):
Instead of being passive tissue that absorbs available nutrients from the mother, the placenta dynamically distributes nutrients between mother and fetus, optimally ensuring the health of both mother and developing baby… [by] receiv[ing] metabolic signals from both the mother and fetus and respond[ing] to this input by regulating the nutrient amounts made available to the fetus.
In other words, this research shows that pregnancy is not a competition between the rights of mother and child (as abortion advocates would have us believe).
