Male hamsters (intact, castrated or testosterone-treated) were tested for their response to dioestrous and to oestrous females. Response to the dioestrous female was measured in terms of proximity and olfactory investigation; response to the oestrous female was measured in terms of mounting, intromission and ejaculation. Interest in dioestrous females declined in parallel with copulatory behaviour after castration and was restored by implantation of testosterone. Six weeks of testosterone treatment failed to restore copulatory behaviour to pre-castration levels; in contrast, interest in the dioestrous female was fully restored. Different components of the behaviour towards dioestrous female changed at different rates; some were restored within a week of implantation while others took several weeks to reach pre-castration levels. As found previously, the tendencies of the male to approach and to leave the female varied independently.
对雄性仓鼠（完整的、阉割的或接受睾酮处理的）进行了测试，以观察它们对动情间期和发情期雌性的反应。通过接近程度和嗅觉探究来衡量对动情间期雌性的反应；通过爬跨、插入和射精来衡量对发情期雌性的反应。阉割后，对动情间期雌性的兴趣与交配行为同步下降，并通过植入睾酮得以恢复。六周的睾酮处理未能将交配行为恢复到阉割前的水平；相比之下，对动情间期雌性的兴趣则完全恢复。对动情间期雌性的行为的不同组成部分以不同速度发生变化；有些在植入后一周内恢复，而其他部分则需要几周时间才能达到阉割前的水平。如先前发现的那样，雄性接近和离开雌性的倾向是独立变化的。
