In this fascinating documentary on transsexuality, Dr. John Money shares his ideas on gender identity. Dr. Money is well known for his research on what makes a person become heterosexual, homosexual, bisexual or transsexual. In this film he presents his ideas on the anatomical and biological factors that steer one towards masculinity or femininity, sorting them out from the historical, cultural and sociological influences. Sex and Money shows people in various stages of transsexual transformation. We see the adaptations they have made with their families and partners, and note that they seem able to lead rather conventional lives.
