Ep. 3 - The Dad Bod Theory (with Lee Gettler)

Birth of a Parent

Why would evolution redesign a man's body after he has children? Anthropologist Lee Gettler helped uncover a surprising answer. His research on hormone changes including testosterone suggests that fatherhood doesn't just change how men think and feel, it changes their biology too.


Shownotes: 

  • Lee’s landmark study Longitudinal Evidence that Fatherhood Decreases Testosterone in Human Males showed that men's testosterone levels decline after becoming fathers, helping reshape our understanding of paternal biology.
  • The Cebu Longitudinal Health and Nutrition Survey (CLHNS) is one of the world's longest-running birth cohort studies, following thousands of families in the Philippines. Many of Lee's landmark findings on fatherhood are based on this dataset.
  • Ruth Feldman's pioneering research on oxytocin, caregiving and parent–infant bonding is discussed during the episode.
  • Explore Lee Gettler's research on fatherhood, hormones and human development.
  • This podcast is part of the Early Childhood Matters platform by the Van Leer Foundation.
