The ability of female mice to return to oestrus following exposure to males perfumed either with oil of wintergreen or with the commercial perfume, "Kanta" was evaluated. Unisexual grouping of female mice induced anoestrus in all individuals. Oestrus was, however, promptly induced in the majority of unisexually grouped females by exposure to normal males. By contrast, exposure to perfumed males failed to induce oestrus in unisexually grouped females. The results suggest that male urine which is the source of the primer pheromone involved in the induction of oestrus was ineffective because of the masking effect of artificial scents. Hence the unisexually grouped females were unable to perceive the pheromone from males and continued to remain in anoestrus following exposure to perfumed males. The results provide additional evidence in support of the view that the urinary pheromone produced by males induces oestrus in females by acting through olfactory pathways.
评估了雌性小鼠在接触用冬青油或商业香水“坎塔”加香的雄性小鼠后恢复发情期的能力。雌性小鼠的单性别分组导致所有个体出现发情间期。然而，通过接触正常雄性小鼠，大多数单性别分组的雌性小鼠迅速进入发情期。相比之下，接触加香雄性小鼠未能使单性别分组的雌性小鼠进入发情期。结果表明，作为诱导发情期的引发信息素来源的雄性尿液由于人工香料的掩盖作用而失效。因此，单性别分组的雌性小鼠无法感知来自雄性的信息素，在接触加香雄性小鼠后仍处于发情间期。这些结果为以下观点提供了额外的证据支持：雄性产生的尿液信息素通过嗅觉途径作用于雌性，从而诱导发情期。
