How your Placenta and Baby "Talk" to Decide when Labor Starts: Conversation with Dr. Todd Rosen
from Making Sense of Pregnancy: What Experts Want you To Know About Your Body · host Paulette Kamenecka
Every popular depiction of a woman in labor that you've ever seen on TV or in movies or experienced yourself contains one real truth: the start of labor is a surprise. It's a surprise because despite the many things we do know about labor, we don't know how or why it's initiated. What series of things have to happen to get labor to turn on, and why-- in one in ten births in the US-- does it turn on too early? This is the topic My guest, Dr. Todd Rosen, talks about today. He and his collaborator Bing bing Wong have developed a compelling theory about the conversation between the placenta and the fetus that may explain what the triggers are.
