The Science of Testosterone: Understanding Sex Differences in Play and Behavior

In this engaging talk, the speaker explores the role of testosterone in shaping sex differences in behavior, particularly in play. Testosterone, present in both sexes but significantly higher in men, influences growth, brain function, and behavior. Drawing from research in behavioral endocrinology and personal experiences, the speaker highlights how rough-and-tumble play is more common in boys due to evolutionary pressures and testosterone levels. She addresses cultural concerns around masculinity, emphasizing that play is not a precursor to toxic behavior but a vital tool for learning social skills. By understanding the biological and social dimensions of sex differences, we can foster a more nuanced and compassionate conversation.
