为了确定性活动期间激素反应的心理生理相关性，在整个测试过程中连续监测13名女性和10名男性的收缩压（SBP）、肛门肌电图（EMG）和肛门光容积脉搏波（APG）。每个受试者完成两次或两次以上的自我刺激测试，持续到高潮后5分钟。连续采集血液样本，测量催产素（OT）水平。在男性和女性中，观察到从基线到高潮的OT和收缩压水平百分比变化之间存在非常高的正相关；高潮前和高潮中，OT和EMG增强；APG和EMG。肛门收缩次数和高潮持续时间也高度相关。高潮的两种模式被定义为存在或不存在高潮收缩之间的静止期。肌电图和APG振幅与性高潮的模式相关。主观高潮强度与高潮迭起的女性的OT水平显著相关。测量之间的正相关性与OT在人类性反应中的可能功能作用一致。
To determine the psychophysiological correlates of hormonal response during sexual activity, systolic blood pressure (SBP), anal electromyography (EMG), and anal photoplethysmography (APG) were monitored continuously throughout testing in 13 women and 10 men. Each subject completed two or more tests of self-stimulation to 5 min beyond orgasm. Blood samples were obtained continuously for measurement of oxytocin (OT) levels. In both men and women, very high positive correlations were observed between the percentage change in levels from baseline through orgasm of: OT and SBP; OT and EMG intensify prior to and during orgasm; APG and EMG. The number of anal contractions and duration of orgasm were also highly correlated. Two patterns of orgasm were defined by the presence or absence of a quiescent period between orgasmic contractions. EMG and APG amplitudes correlated with the pattern of orgasm. Subjective orgasm intensity correlated significantly with increased levels of OT in multiorgasmic women only. The positive correlations between measures are consistent with a possible functional role for OT in human sexual response.
