Intense tonic/clonic uterine contractions and sudden increases in heart rate coincided with the behavioral homolog of a male ejaculatory response (minus seminal emission) in a normal female stump-tailed macaque engaged in homosexual mounting episodes. The behavioral patterns were also observed in four of ten females during 5 to 40 percent of heterosexual copulations. These observations demonstrate the existence of an orgasmic response in a nonhuman primate.
在一只正常的雌性断尾猕猴进行同性骑跨行为时，强烈的强直性/阵挛性子宫收缩和心率突然增加与雄性射精反应（无精液射出）的行为同源现象同时出现。在10只雌性中的4只身上，在5%至40%的异性交配过程中也观察到了这些行为模式。这些观察结果证明了非人类灵长类动物中存在性高潮反应。
