What triggers Spontaneous Labor? A research based theory: conversation with Dr. Todd Rosen (Encore)

 Today I'm gonna share an episode that was originally aired about a year and a half ago about what might be the trigger for starting spontaneous labor. It's kind of amazing that this fundamental experience that all of us have starts with an event that arrives by surprise. In fact, we accept that , labor, if it starts when it starts, will be a surprise. Every popular depiction of a woman in labor that you've seen on TV or in movies or experienced yourself contains at least one real truth. The start of labor is a surprise. It's a surprise because despite the many things we 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 1 in 10 births in the U. S., does it turn on too early? This is the topic my guest, Dr. Todd Rosen, talks about today. Collaborator, Bingbing Wang, have developed a compelling theory about the conversation between the placenta and the fetus. That may explain what these triggers are.
