A penile plethysmograph is a device placed around a male's penis for the purpose of measuring sexual arousal. The plethysmograph is capable of measuring minute changes in the circumference in the penis, and these changes in circumference are presumed to be correlated with sexual arousal. A typical penile plethysmograph examination involves exposing the patient to various visual and/or auditory depictions of sexual behavior and measuring his response to each.
