The current investigation explores possible reasons for the poor overall success rates of medical techniques used in the treatment of erectile dysfunction. This is the first study to compare directly the psychological impact of a mechanically produced versus an erotically produced erection. Subjective and objective parameters of sexual arousal were used to compare the experience of a mechanically attained erection versus an erotically stimulated erection. Twenty-eight (28) men without sexual dysfunction were asked to reach a full erection during each of the following two conditions: (a) by using an ErecAid System and (b) by self-stimulating while watching an erotic video. The results of this study suggest that the penile vacuum device was a successful method for attaining penile tumescence; however, the presence of penile tumescence was not accompanied by a subjective state of physical or mental sexual arousal. Thus, the mere physical presence of an erection does not seem to evoke bodily or mental feelings of sexual arousal. It is important to note that these findings suggest that attention to the psychosexual components of the individual's sexual experience are critical to the subjective experience of sexual arousal and reflect once again the multimodal response systems involved in sexual arousal. These results suggest that more effective treatment approaches would be based on a clinical strategy that provides instruction both on the technical use of a mechanical device as well as on the importance of creating an appropriate psychosexual environment.
当前的调查探讨了用于治疗勃起功能障碍的医学技术总体成功率较低的可能原因。这是第一项直接比较机械产生的勃起与性刺激产生的勃起对心理影响的研究。使用性唤起的主观和客观参数来比较机械获得的勃起与性刺激勃起的体验。28名无性功能障碍的男性被要求在以下两种情况下达到完全勃起：(a) 使用勃起辅助系统；(b) 在观看色情视频时自我刺激。这项研究的结果表明，阴茎真空装置是实现阴茎肿胀的一种成功方法；然而，阴茎肿胀的出现并未伴随着身体或精神性唤起的主观状态。因此，仅仅阴茎勃起似乎并不会引发身体或精神上的性唤起感觉。需要注意的是，这些发现表明关注个体性体验的性心理成分对于性唤起的主观体验至关重要，并且再次反映了性唤起中涉及的多模式反应系统。这些结果表明，更有效的治疗方法将基于一种临床策略，该策略既要提供关于机械设备技术使用的指导，也要说明营造适当性心理环境的重要性。
