Abstract
Two experiments were conducted testing reliability of expansion chamber determined gauge element breakage ranges; 20 trials with sexually functional males provided comparative data on the gauge in actual application. Circumference of the expansion chamber and increases in penile circumference were simultaneously monitored via a mercury strain gauge. Results for both experiments indicated considerable overlap at gauge element breakpoints, and yielded an overall misdiagnosis rate of 15.5% in a young, healthy population.
