Neuroscience and Sexuality

Think 3 Comments 19

Hour 2:     How do differences in our brains determine differences in our physical development and sexual orientation? We’ll talk this hour with neuroscientist Simon LeVay, who first studied these differences over twenty years ago. LeVay’s new book on the subject is “Gay, Straight, and the Reason Why: The Science of Sexual Orientation” (Oxford University Press, Paperback, 2012).

    I thought this was a great discussion! I believe more of the same would beneficially educate gay and straight people on what determines one’s sexuality and thereby creating an atmosphere of acceptance of sexuality overall.

    Contrary to what we heard at the opening of the program, larger identical twin studies show that the genetic influence in shaping one’s sexuality are not as great as other influences. Later in the program, Dr. LeVay did say that genetic influence is only part of the story in shaping human sexuality, according to his calculation about 50%. A 2010 Swedish study of over 7000 identical twins found that genetic influence was much less ranging from 18-39 % while environmental factors accounted for over 60% of shaping the person’s sexual orientation.
