The role of sexual arousal in the etiology and/or maintenance of superficial dyspareunia is still unclear. Lack of sexual arousal may be both the cause and the result of anticipated pain. This study compared genital and subjective sexual responses to visual sexual stimuli of women with dyspareunia and women without sexual complaints. We investigated whether women with dyspareunia were less genitally and subjectively responsive to noncoital (oral sex) as well as coital visual sexual stimuli than women without sexual problems, or whether they exhibited a conditioned anxiety response such that sexual arousal responses were lower only to stimuli that may induce fear of pain (i.e., coitus). A total of 50 women with dyspareunia and 25 women without sexual problems were shown two sexual stimuli, one depicting oral sex and the other one depicting coitus. Genital arousal was assessed as vaginal pulse amplitude using vaginal photoplethysmography. Self-reported ratings of subjective sexual arousal were collected after each erotic stimulus presentation. Women with dyspareunia had comparable levels of genital arousal to two different visual sexual stimuli as women without sexual complaints. Contrary to expectation, there was an indication that women with dyspareunia reacted with higher levels of genital arousal to the explicitly depicted coitus stimulus than controls, whereas controls had higher genital responses to the oral sex stimulus. With respect to subjective sexual arousal, it was found that women with dyspareunia reported less positive feelings in response to both erotic stimuli than controls. We conclude that, with adequate visual sexual stimulation, women with dyspareunia showed equal levels of genital sexual arousal to visual sexual stimuli as women without sexual complaints. Therefore, there was no evidence for impaired genital responsiveness associated with dyspareunia. Also, we found no evidence for a conditioned anxiety reaction in response to exposure to a coitus scene.
性唤起在浅表性性交疼痛的病因和/或维持过程中的作用仍不明确。性唤起不足可能既是预期疼痛的原因,也是其结果。本研究比较了性交疼痛女性和无性方面主诉女性对视觉性刺激的生殖器及主观的性反应。我们调查了性交疼痛女性在生殖器及主观方面对非性交(口交)以及性交视觉性刺激的反应是否比无性问题的女性更弱,或者她们是否表现出一种条件性焦虑反应,即仅对可能引发疼痛恐惧的刺激(即性交)性唤起反应更低。总共向50名性交疼痛女性和25名无性问题女性展示了两种性刺激,一种描绘口交,另一种描绘性交。使用阴道光电容积描记法将生殖器唤起评估为阴道脉搏幅度。在每次呈现色情刺激后收集主观的性唤起自我报告评分。性交疼痛女性对两种不同视觉性刺激的生殖器唤起水平与无性方面主诉的女性相当。与预期相反,有迹象表明性交疼痛女性对明确描绘的性交刺激的生殖器唤起水平高于对照组,而对照组对口交刺激的生殖器反应更高。关于主观的性唤起,发现性交疼痛女性对两种色情刺激的反应所报告产生的积极感受均少于对照组。我们得出结论,在有足够的视觉性刺激下,性交疼痛女性对视觉性刺激的生殖器性唤起水平与无性方面主诉的女性相同。因此,没有证据表明性交疼痛与生殖器反应受损有关。此外,我们也没有发现暴露于性交场景会引发条件性焦虑反应的证据。
