很明显，雄性仓鼠可以区分个体的气味，同种雌性仓鼠，这是通过使用习惯化-非习惯化方法来证明的。然而，从过去的研究中还不清楚雄性仓鼠是否能够区分发情和不发情的雌性仓鼠的气味。通过一系列的习惯化-非习惯化实验来确定雄性是否通过两种雌性分泌物（侧腺分泌物和阴道分泌物）来区分不同的发情周期状态。我们发现，当雄性习惯了雌性侧翼腺分泌时，雄性在试验中会区分这只雌性和另一只雌性，无论是两只都处于发情期，还是两只都处于发情期，或者一只处于发情期而另一只处于发情期。发情期和发情期雌鼠对侧翼腺气味的异常反应程度无显著差异。这些结果表明，雄性主要利用侧翼腺的气味来获取有关个体的信息。在适应-不适应试验中，用阴道分泌物进行测试时，雄性只在第二只雌性发情时表现出调查的差异，这表明雄性主要利用阴道分泌物获取生殖状态的信息。
It is clear that male hamsters discriminate between the odors of individual, conspecific females, as shown by using habituation-dishabituation methods. However, it is not clear from past research whether male hamsters are able to discriminate between the odors of estrous and non-estrous females. A series of habituation-dishabituation experiments were conducted to determine whether males discriminated between different estrous cycle states using two female secretions, those from flank glands and vaginal secretions. We found that, when habituated to a female flank-gland secretion, males discriminated between this female and a second female on the test trial, whether both were in estrus, both were in diestrus, or one was in estrus and the other in diestrus. There was no difference, however, in the magnitude of their dishabituation response toward flank-gland odors of females in estrus and diestrus. These results suggest that males use flank-gland odors to gain information primarily about individuals. When tested with vaginal secretions in habituation-dishabituation tests, males only showed differences in investigation when the second female was in estrus, indicating that males use vaginal secretions to gain information primarily about reproductive state.
