Innie v Outie Labia: Listener Question
Innie vs Outies: no, we are not referring to bellybuttons. In this episode, we’re talking about the labia of the Volva! Does it actually matter? Which one is more common? Now, this episode was actually sparked by a brilliant listener who sent us her question to our IG inbox (as a non-clinician):...

Marfan Syndrome in Pregnancy
Marfan syndrome is an autosomal dominant, connective tissue disorder. Because it’s autosomal dominant, an affected parent has a 50% chance of passing the genetic mutation to their offspring in every pregnancy. Approximately 25% of cases actually stem from spontaneous, de novo mutations with no...

Is Mag Always Needed for PP Readmission for PreE?
If you’ve ever managed postpartum preeclampsia, you know the clinical gray zone: after an initial intrapartum course of magnesium sulfate, when do you actually restart it for a postpartum, readmission exacerbation? Always? There’s no standard national guidance on this. Every unit seems to do...

The LT-O Whole Blood CONTROVERSY
If you’ve been listening for a while, you might remember an episode we ran about two years ago where we dove deep into the use of low-titer O-positive whole blood in emergency resuscitation. At the time, the consensus in trauma care was leaning heavily "pro"—advocating for getting O-positive…

Retest GDM Late 3rd Tri for LGA or Poly? (OCT 2026 Data)
Picture this common, late-gestation conundrum: You’re reviewing a 34-week sono. The mid-pregnancy 24-to-28-week glucose screen was completely normal. But now, the sonogram pops up with an estimated fetal weight of over 90%, or maybe a MVP (or AFI) that’s overtly elevated. The classic clinical...

Routine pp Hgb?
Today we’re diving into a lab order that almost every ob-gyn, midwife, and labor-and-delivery nurse were traditionally trained to do: the routine Postpartum Day 1 Hemoglobin and hematocrit. For decades, checking a patient’s H&H after delivery was automatic. Didn’t matter if it was a smooth,...

The Cerebellum (TCD) as EGA Referee
So, here is a not uncommon situation: A new OB patient presents for initial prenatal care at 28 weeks by “sure LMP” but her ultrasound EGA is just over 3 weeks behind. Simple redating, right? How can we be assured that we are not missing FGR? That is where the “ancillary” use of transcerebellar...

Estrogen’s Protection Against Breast CA: The Underappreciated Data
Today, we are taking a deep dive into a medical truth that sounds completely counterintuitive, almost upside down, based on everything you think you know about women's health. But here’s the kicker: it’s actually nothing new at all. For over two decades, ever since the landmark Women’s Health...

“New” Data: CS Skin Incision To Delivery Interval (AJOG-MFM)
If you practice obstetrics, you already know that our entire world is ruled by a stopwatch. Think about it: we are obsessed with time. We wait exactly 60 or 120 minutes for a gestational diabetes challenge. We stare at a monitor for a strict 30 minutes timing a biophysical profile. The entire...
