Images of Coitus (03:42)

Reproductive physiologist Dr. Roy Levin uses an FMRI scanner to observe a couple having sex. A cross-section shows the penis change shape during intercourse.

Addressing Male Sexual Dysfunction (02:18)

Geddings Osbon invented a practical, mechanical solution for his own impotence. His vacuum pump drew blood into the spongy erectile tissue in the penis.

Viagra (03:32)

In the 1990s, scientists at Pfizer unintentionally created a chemical compound that caused erections by relaxing blood vessels.

HIV/AIDS (03:12)

A new sexually transmitted disease was discovered in the 1980s. Gay men and intravenous drug users became infected with diseases that did not affect other people.

Sexually Transmitted Disease Prevention (05:10)

AIDS has killed more than 30 million people. Infection trends in African tribes led to the knowledge that circumcision reduces the risk of HIV infection by removing Langerhans cells.

Gender Identity (04:28)

The argument over nature versus nurture has focused on the story of Bruce/David Reimer whose penis was burned during circumcision. Dr. John Money was a leading advocate of sex change operations.

Failed Experiment in Gender Neutrality (02:20)

Reimer recalls his experience being raised as a girl after a botched circumcision. Dr. Money assured his mother that it would work. Reimer's twin brother died from a drug overdose.
