What is a Phallometric test?
Phallometry (also known as penile plethysmography) is a technique used in the assessment and treatment of paraphilias in men. In essence, it detects an increase in penile circumference in response to specific visual or auditory stimuli and, on this basis, suggests the nature of the subject’s sexual interests.
What is a PPG test?
The penile plethysmograph (PPG) is a penile sexual arousal test that is often used to help determine whether a male participant is likely or unlikely to respond sexually to a child or adolescent. The results may be used in arriving at an opinion as to whether a person is a likely sex offender or is likely to reoffend.
Is Phallometric testing accurate?
A 1998 large-scale meta-analytic review of the scientific reports demonstrated that phallometric response to stimuli depicting children, though only 32% accurate, had the highest accuracy among methods of identifying which sexual offenders will go on to commit new sexual crimes.

What is diabetes PPG?
A postprandial glucose (PPG) test is a blood glucose test that determines the amount of glucose, in the plasma after a meal. The diagnosis is typically restricted to postprandial hyperglycemia due to lack of strong evidence of co-relation with a diagnosis of diabetes.
