Nocturnal penile tumescence with stamps: a comparative study under sleep laboratory conditions.
The usefulness of nocturnal penile tumescence with stamps to measure erections during sleep has been evaluated under laboratory conditions and compared to strain gauge recording. If the ring of stamps does not break a diagnosis of organic dysfunction is supported. However, if breakage occurs at the perforations no diagnostic conclusion can be made. The diagnostic importance of nocturnal penile tumescence with stamps is limited.
