Chapter

Abstract

Nocturnal penile tumescence and rigidity (NPTR) analysis using the Rigiscan system is composed of two parts: (1) a portable nocturnal penile tumescence and rigidity data-logging unit and (2) a computer with printer for processing and printing the data. The test was developed to study a man’s erectile function while sleeping.
