Becoming a father doesn’t just change your life, research suggests it can actually change your brain. In this episode of Thriving Kids, Dr. Dave Anderson sits down with psychologist and researcher Dr. Darby Saxbe, author of Dad Brain: The New Science of Fatherhood and How It Shapes Men’s Lives, to explore the emerging science of what happens to men’s brains, hormones, relationships, and sense of identity when they become fathers. Dr. Saxbe explains why some of the brain changes associated with fatherhood may help dads become more attuned to their children, how testosterone levels can shift as men move into caregiving roles, and why becoming a parent can bring both psychological vulnerability and long-term neurological benefits. They also discuss paternal mental health, loneliness, and social connection among men, the pressures created by online messages about masculinity, and how being an engaged father can offer men a powerful source of connection and purpose. In this episode, they cover: • How men’s brains can change during the transition to fatherhood • Why some brain changes may help fathers become more responsive to their babies • What researchers are learning about paternal postpartum depression and anxiety • Why the popular idea that “higher testosterone is always better” misses what the research actually shows • How relationships and social connection contribute to men’s long-term health • How fatherhood can encourage healthier behaviors in men Key takeaways • Fathers’ brains change, too. Research suggests that becoming a father is associated with changes in brain structure and function, including areas involved in understanding and responding to other people’s thoughts and emotions. • Those changes can bring both opportunity and vulnerability. In Dr. Saxbe’s research, some of the brain changes associated with stronger bonding and greater caregiving involvement were also associated with more symptoms of anxiety, depression, psychological distress, and sleep problems. • Fathers’ mental health deserves attention. Becoming a parent is a major physical, emotional, and social transition for all parents, yet fathers are often overlooked in conversations about postpartum well-being. • Testosterone isn’t simply a “more is better” hormone. Testosterone can naturally change as men transition into caregiving roles, and Dr. Saxbe argues that flexibility — rather than maximizing testosterone — is a more useful way to understand these changes. • Fatherhood can encourage healthier habits. Research suggests fathers may be more likely to engage in protective health behaviors and less likely to engage in some risky behaviors once they become responsible for a child. • Great parents are made, not born. One of Dr. Saxbe’s central messages is that good parenting isn’t innate. Investment, motivation, practice, and experience help parents develop the skills they need.
