Life history theory and the adaptive calibration model state that characteristics of one's early environment influence individual differences in both neuroendocrine reactivity to stress and sexual risk-taking behavior. However, few studies have directly examined the relationship between neuroendocrine reactivity to stress and risky sexual behavior. This study used multilevel modeling to test whether cortisol reactivity and recovery in response to laboratory stress were associated with women's history of sexual behavior and their sexual arousability in response to laboratory sexual stimuli. Participants were 65 women (35% heterosexual, 44% bisexual, and 21% lesbian) who completed two laboratory sessions, two weeks apart. Women's self-reported sexual arousability to sexual stimuli interacted with their sexual abuse history to predict their trajectories of cortisol stress reactivity and recovery. Cortisol reactivity and recovery were not associated with women's sexual risk taking, such as the age of sexual debut, sociosexuality, or lifetime number of sexual partners.
生活史理论和适应性校准模型表明，一个人早期环境的特征会影响其神经内分泌对压力的反应性和性冒险行为的个体差异。然而，很少有研究直接检验神经内分泌对压力的反应性与危险性行为之间的关系。本研究使用多层模型来检验对实验室压力的皮质醇反应和恢复是否与女性的性行为史以及她们对实验室性刺激的性唤起能力有关。参与者为 65 名女性（35%异性恋、44%双性恋和 21%女同性恋），她们在两周内完成了两个实验室会议。女性对性刺激的自我报告性唤起与其性虐待史相互作用，预测了她们皮质醇应激反应和恢复的轨迹。皮质醇反应和恢复与女性的性冒险行为（如性初夜年龄、社交性或终生性伴侣数）无关。
