Screening impotence by home nocturnal tumescence self-monitoring

Abstract
Twenty subjects complaining of impotence were assessed using nocturnal penile tumescence (NPT), neurological, vascular and hormonal analysis. Subjects undertook NPT in both home and hospital environments: 10 hospital first and 10 home first. The were high levels of agreement between diagnosis using NPT in the two conditions and diagnosis from the physiological tests. There was a high correlation of frequency of erections between the home and hospital conditions, together with a high consecutive night reliability when using the monitor in the home condition (r = .94, p = .001).
