Becoming a dad changes more than your life. It also changes your brain. Among other things, new fathers can experience changes in brain volume and shifts in testosterone. We explore the science of “dad brain” in this episode with @darbysaxbe.bsky.social www.sexandpsychology.com/blog/podcast...

New dads often imagine that they are not biologically “wired” to care for their kids in the same way that moms are. In Dad Brain, @darbysaxbe.bsky.social shows nothing could be further from the truth. An amazing, necessary book!

Everyone is obsessed with testosterone these days - politicians call their opponents "low-T," RFK brags about his HRT, & the market for T supplements has exploded. But men's testosterone drops naturally around the transition to fatherhood, and that's adaptive. I unpack the research in a new essay.

For many men, fatherhood is deeply transformative. It can rewire empathy and priorities, changing how they relate to the wider world. Dads matter, and their unique strengths deserve real recognition. Listen to my full podcast with @darbysaxbe.bsky.social here: open.spotify.com/episode/5Fxa...

My lab asked pregnant couples to discuss their plan for sharing infant care. After birth, we brought them back to the lab. We discovered that couples did not accurately predict their division of baby care, and parents fare better when dads do more. More here: darbysaxbe.substack.com/p/can-couple...

Here's an irony of contemporary society: Most of us who work and socialize in adult spaces get very little time with babies and young children, while parents are isolated and overwhelmed. In my Substack this week, I advocate for more babies in public spaces and more baby time for all!
