In this enlightening conversation, Dr. Carole Hooven, a Harvard biologist and author of "T: The Story of Testosterone," delves into the powerful influence of testosterone on male identity and behavior. She discusses how T underpins sex differences from prenatal development to adulthood, shedding light on both biological and cultural impacts. Historical cases of castration reveal shocking insights into masculinity, while the hormone's effects on aggression and nurturing are thoroughly examined. Hooven also passionately advocates for celebrating positive masculine traits.

Testosterone's Influence
Testosterone is a key driver of sex differences, particularly in male behavior.
Culture shapes how these differences are expressed, but biology lays the foundation.
insights INSIGHT
Arguments Against Testosterone
Critics acknowledge testosterone's role in physical differences but downplay its impact on the brain and behavior.
They argue that social and cultural influences are the primary drivers of behavioral sex differences.
insights INSIGHT
Early Testosterone Effects
Testosterone production starts prenatally in males, shaping reproductive development and potentially influencing brain development.
Castration studies, like the castrati singers, reveal testosterone's crucial role in libido and secondary sex characteristics.

In 'T: The Story of Testosterone, the Hormone that Dominates and Divides Us', Carole Hooven delves into the role of testosterone in shaping human sex differences, behavior, and societal dynamics. The book provides a clear and accessible review of the scientific literature on testosterone, discussing its effects on development, aggression, and gender identity. Hooven argues for the importance of understanding testosterone's biological influence while acknowledging the complexity of its interaction with social factors.
Demonic males
Richard Wrangham
Demonic Males examines the evolutionary factors contributing to human male violence by studying the behaviors of chimpanzees and other great apes. The book contrasts the aggressive societies of chimpanzees with the more peaceful bonobos, highlighting the role of social structure and female dominance in reducing violence. It argues that while humans have a genetic predisposition to violence, societal structures and intelligence can mitigate these tendencies.
What creates the differences between the sexes? Many would point to culture, and my guest today would agree that culture certainly shapes us. But she’d also argue that at the core of the divergence of the sexes, and in particular, of how men think and behave, is one powerful hormone: testosterone.
Her name is Dr. Carole Hooven, and she’s a Harvard biologist and the author of T: The Story of Testosterone, the Hormone That Dominates and Divides Us. Today on the show, Carole explains the arguments that are made against testosterone’s influence on shaping men into men, and why she doesn’t think they hold water. She then unpacks the argument for how testosterone does function as the driving force in sex differences, and how it fundamentally shapes the bodies and minds of males. We delve into where T is made, how much of it men have compared to women, and what historical cases of castration tell us about the centrality of testosterone in male development. We then discuss how T shapes males, starting in the womb, and going into puberty and beyond, before turning to its influence in athletic performance. We end our conversation with Carole’s impassioned plea for celebrating what’s great about men.
