And basically what I want to know is what was the biggest, was there a big outcome? Like, did you have certain expectations going into the study about what you might find? Were there any surprises along the way? And what do you think might have been the biggest takeaways from all this research?
16:12
Yes.
16:13
Well, I think starting off with the physiology paper and what I've learned over these years about oxytocin physiology in labor and birth is really the effects on the brain.
16:22
You know, it's not just a oxyfastosin birth it's not just a hormone that makes birth go fast that causes those contractions of the uterus but it's actually released from the brain in a specific way in labor you know in a pulsatile release from the brain to the uterus but also at the same time within the brain so all the time that these contractions are happening and the contraction is getting stronger and stronger the brain release is increasing and that has pain relieving effects it has calming and soothing effects it activates the pleasure and reward centers, which is kind of explain some of those things of my own experience really.
16:56
And all the writing I did about ecstatic birth, because when these reward and pleasure centers are activated and this is, this is general of all mammals, right? I'm not just talking about women here, but the reward and pleasure centers get activated through labor and birth, the dopamine centers.
17:11
And then the mother meets her babies for the first time straight after birth.
17:14
And she gets the sensory information, you know, the, the smell of them, the look of them, the feel of them, the taste of them.

And so everything can track differently, right?

small,

becomes bigger and bigger, and in the end becomes virtually unstoppable.
20:50
So one of the oxytocin feedback systems is what's sometimes called the Ferguson reflex.
20:56
So what happens is that as labor progresses, the baby starts moving down in the pelvis and activates specific senses, specific sensory nerves in the lower vagina and cervix.
21:09
And the activation of this nerve sends a message to the brain.
21:13
And that message says, release more oxytocin.
21:16
So release more oxytocin, travels to the uterus, binds to the receptors, triggers more contractions, baby gets pushed lower.

pre-labor cesareans and like scheduled cesareans and how it's the safest way to birth and um you know you're saving your parts um there's there's all these positives and and i just as you're speaking and thinking about women who are choosing a way of birthing where they miss this entire like hormonal like they're opting out of an entire hormonal cascade that It sounds like it's going to be the best setup that you can have with your baby and not even realize that that's it.
