The Secret of sex

One of a four-part series presenting research and breakthroughs in the field of human genetics. This segment examines aspects of reproduction, as well as what being male or female means at the cellular level. Dr. Roy Levin, a reproductive physiologist, uses an FMRI scanner to glean surprising images from a couple having intercourse. Startling physiological effects are seen over a mere six months in a woman who begins testosterone therapy. Experts include Marc Breedlove, Professor of Neuroscience at Michigan State University; Dr. Peter Goodfellow, authority on the Y chromosome; Professor John Burn, clinical geneticist at Newcastle University; Dr. John Manning, leading specialist on testosterone; and Dr. Melissa Hines, Professor of Psychology at City University who has studied testosterone's influence on how children play.
