Abstract:
The measurement and interpretation of nocturnal penile tumescence (NPT) studies depend on appropriate measurement techniques, knowledge of the conditions during which NPT was recorded, and a lack of preconceived notions about the relationship of penile circumference to penile rigidity. This case report illustrates several of the most common problems in the measurement and interpretation of NPT that could result in a false positive finding.
