Physiological responses to sexual stimuli may contribute to the increased rate of sexual problems seen in women with childhood sexual abuse (CSA) histories. We compared two physiological stress responses as predictors of sexual function and satisfaction, sympathetic nervous system (SNS) activation and cortisol in women with (CSA, = 136) and without CSA histories (NSA, = 102). In CSA survivors, cortisol response to sexual stimuli did not significantly predict sexual functioning; however, in NSA women, cortisol increases were associated with poorer sexual functioning, and decreases with higher functioning. For women with CSA histories, lower SNS activity was associated with poorer sexual functioning. For CSA survivors with low lifetime trauma, lower SNS activity was associated with higher sexual satisfaction; for women with high lifetime trauma, the reverse was true. Decreased SNS activity during sexual stimuli predicted higher sexual functioning in NSA women with low lifetime exposure to traumatic events, but lower sexual functioning in those with high exposure. Differences between women with and without CSA histories in the association between cortisol and SNS response and sexual functioning and satisfaction suggests that CSA causes disruptions in both short and long-term stress responses to sexual stimuli that perpetuate into adulthood.
对性刺激的生理反应可能导致有童年性虐待（CSA）史的女性出现性问题的几率增加。我们比较了两种生理应激反应，以此作为性功能和性满意度的预测指标，即有CSA史（CSA组，n = 136）和无CSA史（非CSA组，n = 102）女性的交感神经系统（SNS）激活和皮质醇水平。在CSA幸存者中，皮质醇对性刺激的反应并不能显著预测性功能；然而，在非CSA女性中，皮质醇水平升高与较差的性功能相关，而皮质醇水平降低与较好的性功能相关。对于有CSA史的女性，较低的SNS活动与较差的性功能相关。对于终生创伤程度较低的CSA幸存者，较低的SNS活动与较高的性满意度相关；对于终生创伤程度较高的女性，则相反。性刺激期间SNS活动降低，预示着终生遭受创伤事件暴露程度较低的非CSA女性性功能较高，但在暴露程度较高的女性中则预示着性功能较低。有和没有CSA史的女性在皮质醇与SNS反应以及性功能和性满意度之间的关联存在差异，这表明CSA会导致对性刺激的短期和长期应激反应中断，并持续到成年期。
