背景虽然阴蒂对刺激更敏感，其神经支配比阴道更有利于感觉反馈，但性心理生理学领域使用包括生殖器反应测量在内的心理生理学方法来研究性唤起，严重依赖于阴道而不是阴蒂的测量，目的研制和测试一种用于测量阴蒂脉冲幅度（CPA）的新型阴蒂光电体积描记器，其传感器和光源的方向不同（平行与成角度），在15名绝经前性功能正常的妇女中进行测试。同时评估阴道脉冲幅度（VPA）。这些女性观看了3分钟的色情和焦虑诱导电影片段，每个阴蒂传感器，穿插中性视频摘录。此外，他们还被要求在色情视频演示期间和之后表明他们的主观性唤起水平。结果主要的结果指标是CPA、VPA和主观性唤起。结果阴蒂光体积描记器成功检测到CPA。倾斜传感器的信号质量最好。电影的主要影响和电影和时代之间的相互作用更强的阴蒂比阴道装置。此外，CPA比VPA更密切地跟踪性电影强度的变化。内和受试者之间的相关性生殖器的反应和主观性唤起更高的阴蒂比阴道device.Clinical TranslationComparison CPA与其他生殖器的血流措施在临床样本中表示，可能有助于改善生理评估的性反应women.Strengths和LimitationsOur样本是小的，包括健康志愿者。未来的研究可以检查重测信度，包括多个记录会话，并进一步探讨CPA的特异性，通过比较性和非性刺激与积极value.ConclusionThis研究提出了第一个工具，成功地测量CPA。
BackgroundAlthough the clitoris is more sensitive to stimulation and its innervation more conducive to sensory feedback than the vagina, the field of sexual psychophysiology, which uses psychophysiological methods including genital response measures to study sexual arousal, relies heavily on the measurement of vaginal, rather than clitoral, pulse amplitude.AimTo develop and test a new clitoral photoplethysmograph for the measurement of clitoral pulse amplitude (CPA).Methods2 versions of the new device, which differed in the orientation of the sensor and light source (parallel vs angled), were tested in 15 premenopausal, sexually functional women. Vaginal pulse amplitude (VPA) was assessed simultaneously. The women viewed a 3-minute erotic and an anxiety-inducing film segment with each clitoral sensor, interspersed with neutral video excerpts. In addition, they were asked to indicate their subjective level of sexual arousal during and after erotic video presentations.OutcomesThe main outcome measures are CPA, VPA, and subjective sexual arousal.ResultsThe clitoral photoplethysmograph successfully detected CPA. The quality of the signals was best for the angled sensor. Main effects of the film and the interaction between the film and epoch were stronger for the clitoral than for the vaginal device. In addition, CPA followed more closely changes in intensity of sexual films than VPA. Within- and between-subject correlations between genital response and subjective sexual arousal were higher for the clitoral than for the vaginal device.Clinical TranslationComparison of CPA with other genital blood flow measures in clinical samples is indicated and may contribute to improved physiological assessments of sexual response in women.Strengths and LimitationsOur sample was small and consisted of healthy volunteers. Future research could examine test-retest reliability, by including multiple recording sessions, and further explore the specificity of CPA by comparing sexual and non-sexual stimuli with positive valence.ConclusionThis study presents the first instrument to successfully measure CPA.
