Penile Plethysmograph (PPG) - Forensic Psychology Centre : Forensic Psychology Centre
Penile plethysmography PPG or phallometry is measurement of bloodflow to the penis , typically used as a proxy for measurement of sexual arousal. The most commonly reported methods of conducting penile plethysmography involve the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge , or the volume of the penis with an airtight cylinder and inflatable cuff at the base of the penis. Corpora cavernosa nerve penile plethysmographs measure changes in response to inter-operative electric stimulation during surgery. The volumetric procedure was invented by Kurt Freund and is considered to be particularly sensitive at low arousal levels. The easier to use circumferential measures are more widely used, however, and more common in studies using erotic film stimuli. A corresponding device in women is the vaginal photoplethysmograph.

The penile plethysmograph PPG is an assessment method that can be used to detect sexual deviancy. In order to maximize the likelihood that risk assessments are as accurate as possible and interventions are effective with sex offenders, treatment should focus on the changeable factors that are known to be associated with sexual recidivism i.

A stretchable band with mercury in it is fitted around the subject's penis. The band is connected to a machine with a video screen and data recorder. Any changes in penis size, even those not felt by the subject, are recorded while the subject views sexually suggestive or pornographic pictures, slides, or movies, or listens to audio tapes with descriptions of such things as children being molested. Computer software is used to develop graphs showing "the degree of arousal to each stimulus.
