Abstract
A study was conducted to investigate the validity of nocturnal penile tumescence recording with stamps. To obtain precise measurement of the relationship between stamp breakage and erection normal, potent men were studied in a controlled laoratory setting. Full erection was required before breakage occurrred. Although the data obtained offer some support for the potential value of using nocturnal penile tumescence stamps in the differential diagnosis of impotence, several issues must be resolved before the clinical value of this simple technique can be established.
