Paternology (FATHERHOOD) with Darby Saxbe

Ologies with Alie Ward1h 21mJune 10, 2026
AI-Generated Summary

The podcast "Ologies" dives deep into the science of fatherhood with Dr. Darby Saxbe, a clinical psychologist and researcher at USC whose lab studies how parenthood transforms men’s brains, hormones, and relationships. Contrary to the myth that fatherhood is a passive role, Saxbe reveals that men undergo profound biological changes—like drops in testosterone and shrinkage in brain gray matter—designed to make them more nurturing and efficient caregivers. These changes, she argues, are not signs of decline but evolutionary adaptations for high-investment parenting. The episode dismantles the idea that fatherhood is a natural, instinctive role, showing instead that it’s a skill built through practice, presence, and emotional labor. Saxbe highlights how modern dads are increasingly involved—especially educated, affluent ones—yet systemic inequalities persist, with lower-income men often working more and having less time to parent. She also explores the cultural myths around fatherhood, from the "dad bod" to toxic masculinity, and reveals how pop culture often portrays dads as bumbling fools rather than capable caregivers. The episode ends with a powerful call to action: fatherhood isn’t just about genetics or biology—it’s about choice, connection, and the collective responsibility to raise better, more compassionate men and children. The most striking revelation? Fatherhood isn’t a side gig—it’s a full-time transformation.

Key Takeaways
1

Men’s testosterone drops after a baby’s birth, signaling a shift from mating to parenting mode.

2

Dads’ brains lose gray matter volume, which increases efficiency and helps process the complex demands of parenting.

3

Skin-to-skin contact with newborns benefits babies’ heart rate, temperature, and emotional regulation—just like with moms.

4

The number of dads who’ve never changed a diaper has dropped from 43% to just 3% in recent decades.

5

Dads who are involved in parenting improve their kids’ emotional regulation, academic outcomes, and reduce incarceration risk.

And I say in the book, like great fathers are made not born. It's like we think of caregiving as this like innately wired trait and it's really more like a skill that we learn and that we develop through practice and through time.
