Abstract:
PURPOSE: This study evaluated the diagnostic utility of a 3-Dimensional head mounted display(HMD) in audiovisual sexual stimulation(AVSS). MATERIALS AND METHODS: A total of 45 men were included in this study: 15 healthy, 15 patients diagnosed with organic impotence, and 15 patients with psychogenic impotence. The NEVA(Nocturnal Electrobioimpedance Volumetric Assessment) system was performed during AVSS with both the 3-D HMD and a conventional monitor. In this study, normal erection was defined as a change in penile blood volume of more than 200% over the baseline for more than 5 minutes. After AVSS, each subject rated his sexual drive as grade I(poor), II(moderate), or III (good). RESULTS: Use of the conventional monitor produced a normal state in 8 men: 5 healthy volunteers(33%) and 3 patients with psychogenic impotence(20%). Use of the 3-D HMD produced a normal state in 23 men: 12 healthy volunteers(80%) and 11 patients with psychogenic impotence(73%). In the healthy volunteers and psychogenic impotence group, the duration of erectile events and percent of volume increase from baseline increased significantly more with 3-D HMD than with the conventional monitor. Compared to results using the conventional monitor, the subjects' sexual drive with 3-D HMD was also significantly increased(p<0.05). CONCLUSIONS: AVSS with 3-D HMD improves the recording of physiological erectile response and may be a valuable tool in making the correct diagnosis of erectile dysfunction.
