Clinical psychologist and USC professor Dr. Darby Saxbe joins The Male Room to unpack the science behind fatherhood, from the ways caregiving reshapes the brain to how testosterone, sleep loss, stress and postpartum mood changes can affect new dads. Drawing from her new book Dad Brain, Saxbe explains why great fathers are made through practice, presence and repetition and not just biology. The conversation also explores dad bods, men’s mental health, changing gender roles, sitcom father stereotypes and why modern fatherhood is far more flexible, complicated and rewarding than old clichés suggest.
