How Hormones Shape Sexual Orientation & Behavior | Dr. Marc Breedlove

Mar 30, 2026 | Dr. Marc Breedlove, PhD, is a professor of neuroscience at Michigan State University and an expert on how hormones shape brain development and sexual orientation. We discuss how prenatal testosterone impacts whether someone is romantically attracted to men or women later in life, and what correlates of sexual orientation — such as finger-length ratios — tell us about the role of hormones in brain and psychological development. We also discuss why the number of older brothers a male has biases sexual orientation. Throughout, we explain how nature and nurture interact to shape male-female differences, behavior, and romantic partner choice.

Jewish 101: Ep. 17 - Sex in Judaism

Oct 15, 2011 • Human sexuality in the Jewish tradition is reviewed in an ongoing study of the story of the Garden of Eden, including the rabbinic view of female sexuality, birth control, and the day most appropriate for sexual relations. Taught by Rabbi Mark S. Golub.

I post this video because much in it is so different from the Christian view and perspective. Indeed, much of it is in stark contrast with the Christian view of sexual desire and behaviour. It is most interesting to learn a completely different approach to this issue. Listening to what this rabbi has to say on the matter is well worth your time. – Mark
