title: Penile tumescence monitoring during morning naps: a pilot investigation of a cost-effective alternative to full night sleep studies in the assessment of male erectile disorder.
abstract: Although nocturnal penile tumescence (NPT) monitoring during full night sleep studies provides valuable information in the assessment of male erectile disorder, it is expensive and inconvenient. With the goal of reducing this cost and inconvenience, we investigated the use of penile tumescence monitoring during morning naps. Seven healthy male S s abbreviated their previous night's sleep and then came to an outpatient setting for a morning nap. Sleep and penile tumescence measures were recorded continuously during a 3-hr nap. All subjects slept well (M = 92.8% sleep efficiency) and experienced at least one sleep erection (M = 2.0) with significant circumference change (M = 37.3 mm). These preliminary findings suggest that tumescence monitoring during naps may be useful as an inexpensive and convenient screening approach in the assessment of male erectile disorder.
