Paternology (FATHERHOOD) with Darby Saxbe
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.
Men’s testosterone drops after a baby’s birth, signaling a shift from mating to parenting mode.
Dads’ brains lose gray matter volume, which increases efficiency and helps process the complex demands of parenting.
Skin-to-skin contact with newborns benefits babies’ heart rate, temperature, and emotional regulation—just like with moms.
The number of dads who’ve never changed a diaper has dropped from 43% to just 3% in recent decades.
Dads who are involved in parenting improve their kids’ emotional regulation, academic outcomes, and reduce incarceration risk.

Meet Dr. Darby Saxbe: A Neighbor and Researcher

The Research Gap: Why Fatherhood Is Understudied
Saxbe reveals that research on fatherhood is severely underrepresented—10 times less than maternal research. She explains that while men are now more involved in childcare, science hasn’t caught up, leaving a critical gap in understanding male parenting.
Historical Shifts: From Hunter-Gatherers to the Industrial Revolution
The episode traces fatherhood across human history, showing that for 95% of human existence, men were deeply involved in child-rearing through alloparenting. The Industrial Revolution created a false dichotomy: work for men, home for women.
The Science of Dad Brain: Hormones and Brain Changes
“Losing gray matter may sound worrisome, but it isn't necessarily a bad thing. It can signal pruning of sorts, she writes, eliminating the weaker connections to increase efficiency.”
“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.”
“I would say first, you matter. You can make great contributions to a kid's life. Your involvement can take stress off your partner. It's good for society. It's ultimately good for you too, for your aging, for your well -being, to be more socially connected.”
“Saxby continues that losing gray matter may sound worrisome, but it isn't necessarily a bad thing. It can signal pruning of sorts, she writes, eliminating the weaker connections. to increase efficiency.”
