The importance of hamster vaginal secretion relative to other femine odors for attraction of males and elicitation of copulatory behavior was examined by comparing the behavior of males toward normal females with that toward vaginectomized females. Males were more attracted to intact females than to vaginectomized females when odors were the only cues available and also when auditory, visual, and odor cues were available but contact was prevented. There were no differences in the attractiveness of estrous and diestrous females, whether intact or vaginectomized. When males and females were allowed to interact, there were no differences in any measures of male sexual behavior toward normal versus vaginectomized females, which indicates that the presence of vaginal secretion is not necessary for male sexual behavior. The significance of these findings for conceptions of pheromone action in mammals is discussed.
通过比较雄性对正常雌性和阴道切除雌性的行为，研究了仓鼠阴道分泌物相对于其他雌性气味在吸引雄性和引发交配行为方面的重要性。当气味是唯一可用线索时，以及当听觉、视觉和气味线索都可用但接触被阻止时，雄性对未切除阴道的雌性比切除阴道的雌性更感兴趣。发情期和非发情期的雌性，无论是否切除阴道，其吸引力没有差异。当雄性和雌性被允许相互作用时，雄性对正常雌性和切除阴道雌性的性行为的任何测量指标都没有差异，这表明阴道分泌物的存在对雄性性行为不是必需的。讨论了这些发现对哺乳动物信息素作用概念的意义。
