雄性大鼠性动机的检测方法与评价指标研究进展

Detection methods and evaluation indexes of sexual motivation in male rats:An update

性动机是指在有配偶时,发生性行为的可能或接近潜在性伴侣的意愿强度,对性健康具有重要意义。目前,性欲低下已成为日益突出的社会问题,但其检测评估尚无统一标准。本文系统梳理了雄性大鼠性动机的常用检测方法,包括雌雄交配类、竞争选择类和任务习得类三大类,同时论述相关评价指标及各种方法的优缺点,并深入探讨性动机的本质,阐述性接触行为是性动机的直接体现,建议相关研究重点关注接触行为,并需要区分性接近和社会性接近。

Sexual motivation refers to the intensity of willingness to have sex with or near a potential partner and is important for sexual health.At present,low sexual desire has become an increasingly prominent social problem,and there are no unified standards for its detection and evaluation.In this paper,we systematically sorted out the commonly used methods for detecting sexual motivation in male rats,including the three major categories of male-female mating,competitive selection and task acquisition,and discussed the relevant evaluation indexes and the advantages and disadvantages of various methods.We also explored the nature of sexual motivation,elaborated sexual contact behavior as a direct manifestation of sexual motivation,and proposed focusing relevant studies on contact behaviors and differentiating sexual proximity from social proximity.
