Using a three-dimension head mounted displayer in audio-visual sexual stimulation aids in differential diagnosis of psychogenic from organic erectile dysfunction.
We designed this study to compare the efficacy of using a three-dimension head mounted displayer (3-D HMD) and a conventional monitor in audio-visual sexual stimulation (AVSS) in differential diagnosis of psychogenic from organic erectile dysfunction (ED). Three groups of subjects such as psychogenic ED, organic ED, and healthy control received the evaluation. The change of penile tumescence in AVSS was monitored with Nocturnal Electrobioimpedance Volumetric Assessment and sexual arousal after AVSS was assessed by a simple question as being good, fair, or poor. Both the group of healthy control and psychogenic ED demonstrated a significantly higher rate of normal response in penile tumescence (P<0.05) and a significantly higher level of sexual arousal (P<0.05) if stimulated with 3-D HMD than conventional monitor. In the group of organic ED, even using 3-D HMD in AVSS could not give rise to a better response in both assessments. Therefore, we conclude that using a 3-D HMD in AVSS helps more to differentiate psychogenic from organic ED than a conventional monitor in AVSS.
