How to Measure Arousal and Penis With Metoidioplasty

Cecile Cisco used a rubber band to measure arousal in her lab. She was the first person with micro penises to do so, but it's not clear if there are any differences between men and women who have them. The research is based on metoidioplasty, which creates a penis that is roughly analogous in size to an average three-inch penis. It would be unlikely for someone like this to experience discomfort when they were aroused by these gauges because of their small size.
