We investigated the appearance of penile tumescence during periods of day napping in a population of 18 impotent men who, in addition, underwent a comprehensive sleep investigation for impotence, including polysomnographic recording and nocturnal penile tumescence monitoring. Of the subjects 16 (88%) had rapid eye movement sleep during the night. Four patients who did not have erections on 2 separate sessions of nocturnal sleep recording also did not experience penile tumescence during the day. Of the 12 patients with documented erections at night 9 (75%) also exhibited erectile episodes during napping. Diurnal penile tumescence recording is less cumbersome, less expensive and more convenient to perform than its nocturnal counterpart. Diurnal penile tumescence appears to be a summary reflection of nocturnal penile tumescence episodes. The consistency between nocturnal and diurnal penile tumescence suggests that further study of this new technique is worthwhile. Validation of diurnal penile tumescence may offer a viable alternative to the comprehensive assessment of impotent men.
