Past findings on the diagnostic sensitivity of vaginal photoplethysmography are limited by testing among women with heterogeneous sexual dysfunctions and by the use of statistical techniques that are unable to assess how changes in subjective arousal are associated with changes in physiological arousal.
The aims of this study were to: (i) test the sensitivity of vaginal photoplethysmography and continuous measures of subjective sexual arousal in differentiating between women with and without sexual arousal or orgasm dysfunction; and (ii) examine the diagnostic utility of measuring the synchrony between genital and subjective sexual responses.
Sexual arousal was assessed in sexually healthy women (n = 12), women with orgasm disorder (OD; n = 12), and 38 women who met the criteria for the three subcategories of sexual arousal dysfunction described by Basson et al. (i.e., genital sexual arousal disorder [GAD; n = 9], subjective sexual arousal disorder [SAD; n = 13], and combined genital and subjective arousal disorder [CAD; n = 16]).
Physiological sexual arousal was assessed using vaginal photoplethysmography, and subjective sexual arousal was measured continuously and using a Likert-scale in response to sexual videos.
Women with GAD showed the lowest and women with CAD showed the highest levels of vaginal pulse amplitude response to erotic stimuli. Women with sexual arousal disorder showed significantly lower levels of subjective sexual arousal to erotic stimuli than did sexually healthy women. Relations between subjective and physiological measures of sexual arousal were significantly weaker among women with sexual arousal disorder than sexually healthy women or women with OD.
Preliminary support was provided for the diagnostic utility of measuring the synchrony between subjective and genital arousal in women with sexual arousal disorder. Findings do not support the sensitivity of using vaginal photoplethysmography, or continuous or Likert-scale measures of subjective arousal for differentiating between subtypes of women with sexual arousal disorder.
过去关于阴道光体积描记法诊断敏感性的研究结果受到以下因素的限制：研究对象为性功能障碍各异的女性，以及使用无法评估主观唤醒变化与生理唤醒变化之间关联的统计技术。
本研究旨在：（i）测试阴道光体积描记法和连续测量主观性唤起的敏感性，以区分有和无性唤起或性高潮功能障碍的女性；以及（ii）检查测量生殖器和主观性反应同步性的诊断效用。
对 12 名性健康女性、12 名性高潮障碍（OD）女性和 38 名符合 Basson 等人描述的性唤起障碍三个亚类标准的女性（即生殖器性唤起障碍[GAD；9 名]、主观性唤起障碍[SAD；13 名]和生殖器和主观性唤起障碍综合[CAD；16 名]）进行性唤起评估。使用阴道光体积描记法评估生理唤起，使用连续测量和 Likert 量表评估对性视频的主观唤起。
性唤起的生理评估使用阴道光体积描记法，主观性唤起的评估采用连续测量和 Likert 量表，以性视频作为刺激。
GAD 女性对性刺激的阴道脉搏幅度反应最低，CAD 女性最高。性唤起障碍女性对性刺激的主观性唤起明显低于性健康女性。性唤起障碍女性的主观和生理性唤起之间的关系明显弱于性健康女性或 OD 女性。
初步支持了在性唤起障碍女性中测量主观和生殖器唤起同步性的诊断效用。研究结果不支持使用阴道光体积描记法、连续或 Likert 量表测量主观唤起来区分性唤起障碍女性的亚类的敏感性。
