| Abstract: | Fourteen subjects participated in a sleep study designed to document the reliability of measurements of REM-related vaginal blood-flow changes. Several standard sleep parameters were also examined for comparison with vaginal measures. The most reliable vaginal measure was the maximal change in disengorgement for a given REM period averaged across a night of REM periods. The reliability of this measure compared favorably with that of a highly reliable computerized measure of REM density. It is suggested that nocturnal vaginal blood-flow measures have sufficient reliability to be useful in the differential diagnosis of organic and psychogenic sexual dysfunction.This study was supported in part by a training grant to the Department of Clinical Psychology, University of Florida, Gainesville (USPHS532DE07133-02), and a grant from the NIH (USPHSCA26364R073241-29) to the second author. |
