How does sex affect testosterone?

Sexual activity can increase testosterone levels in both males and females. According to Andrew Huberman, research spanning many decades, including both animal and human studies, indicates that engaging in sex, particularly sex that does not culminate in ejaculation (for males), may further boost testosterone levels. However, the data are not entirely clear, possibly due to the challenges in organizing such studies and ensuring accurate self-reporting from participants. It's important to note that these effects are most significant when the sexual relationship is healthy, consensual, and appropriate in context and age 1.
