Nocturnal penile tumescent evaluation of erectile function in insulin-dependent diabetic men

Abstract
Summary This study compared nocturnal penile erections in four age-matched groups of young subjects: diabetic patients with and without erectile problems, psychogenically impotent men and healthy control subjects. All men were assessed under similar conditions during three nights, each for a total of 156 study nights. Diabetic impotent men exhibited a significantly decreased number of erectile episodes (ppppp<0.05).
