According to the article:
The men hooked themselves up to a rubber-band-like device that detected erections by measuring the thickness of the penis. The women used a small device that shines a light into the vagina and detects reflected light. According to Bailey, the vagina becomes darker during arousal.
Pretty interesting. I wonder if it changes as a woman ages, and if it is independent of or dependent on culture.
