Research indicates hysterectomy surgery may adversely affect the pelvic autonomic nerves and autonomic mechanisms are integral to the sexual arousal response in women. This study explored the possibility that women who undergo hysterectomy may experience an impaired vasocongestive response to erotic stimulation. Thirty-two women with a history of benign uterine fibroids who had ( n = 15) or had not ( n = 17) undergone hysterectomy participated in two experimental sessions in which self-report and physiological (vaginal pulse amplitude; VPA) sexual responses were recorded during an erotic film presentation. In one of the sessions, the women exercised on a treadmill for 20 min prior to viewing the erotic films as a means inducing autonomic arousal. Exercise significantly increased VPA but not subjective sexual responses in both groups of women. VPA responses were marginally higher among the fibroid than hysterectomy group in the no-exercise condition. The hypothesis that physiological sexual arousal may be impaired with hysterectomy surgery was only partially supported.
研究表明,子宫切除术可能会对盆腔自主神经产生不利影响,而自主神经机制是女性性唤起反应不可或缺的一部分。本研究探讨了接受子宫切除术的女性对性刺激的血管充血反应可能受损的可能性。32名有良性子宫肌瘤病史的女性参与了两个实验环节,其中15名接受过子宫切除术,17名未接受过子宫切除术。在观看色情影片期间,记录她们的自我报告和生理(阴道脉搏振幅;VPA)性反应。在其中一个环节中,女性在观看色情影片前在跑步机上锻炼20分钟,以此诱导自主神经兴奋。锻炼显著增加了两组女性的VPA,但没有增加主观的性反应。在不锻炼的情况下,肌瘤组的VPA反应略高于子宫切除组。子宫切除术可能会损害生理性唤起的这一假设仅得到了部分支持。
