Female golden hamsters (Mesocricetus auratus) which have actively terminated mating with one male will respond in succession to two or more novel males. However, mating with the first male results in a reduction in receptivity shown toward a second male, with the size of the decrease being proportional to the amount of copulatory stimuli provided by the first male. Furthermore, the decreased receptivity shown toward the second male results in his achieving fewer ejaculations. These effects are more pronounced when the second mating occurs 5 min or 8 h after the first mating than when it occurs 1 or 4 h later, suggesting both short-term and long-term inhibitory effects. Copulation with a single male also effects a 40% shortening of behavioral receptivity. In a promiscuous species such as the hamster, prolonged copulation by the male may enhance the short-term inhibition of female receptivity, thereby reducing the risk of subsequent sperm displacement. The long-term effect occurs too late to affect sperm competition and may, instead, function to reduce the risk of predation as a result of unnecessary further mating.
主动终止与一只雄性仓鼠交配的雌性金黄仓鼠（Mesocricetus auratus）会相继对两只或更多只陌生雄性仓鼠产生反应。然而，与第一只雄性仓鼠交配会导致对第二只雄性仓鼠的接受度降低，降低的程度与第一只雄性仓鼠提供的交配刺激量成正比。此外，对第二只雄性仓鼠接受度的降低导致它射精次数减少。当第二次交配在第一次交配后5分钟或8小时进行时，这些影响比在第一次交配后1小时或4小时进行时更为明显，这表明存在短期和长期抑制作用。与单一雄性仓鼠交配还会使行为接受期缩短40%。在仓鼠这样的滥交物种中，雄性仓鼠长时间交配可能会增强对雌性接受度的短期抑制，从而降低后续精子被取代的风险。长期影响发生得太晚，无法影响精子竞争，相反，它可能起到降低因不必要的进一步交配而被捕食的风险的作用。
