In this episode, Armand DiMele explores the fascinating and often overlooked topic of human semen and its impact on well-being. Drawing on research from evolutionary psychologists, he discusses how certain compounds in semen can influence female biology and mood. The episode delves into the phenomenon of menstrual synchrony among heterosexual women and the absence of this effect in homosexual women and those using contraceptives. DeMille highlights the mood-enhancing chemicals found in semen, including cortisol and oxytocin, and their potential effects on mental health. While acknowledging the importance of understanding these findings, he also cautions against misusing this information, particularly in the context of sexual health.
