Do nocturnal penile tumescence recordings alter electroencephalographic sleep?
While concurrent monitoring of sleep is considered to be a necessary component of evaluating nocturnal penile tumescence (NPT), in order to ensure that NPT data are not invalidated by fragmented sleep or diminished REM sleep, it is not known whether NPT recording itself disrupts sleep beyond the expected first night effect. In this study of 42 outpatient men with major depression and 36 normal control subjects, we found no effect of NPT recording on measures of sleep continuity, proportion of NREM to REM sleep, or REM sleep in either depressed or healthy control subjects.
