交配会改变雌性的行为和生理，对雄性和雌性的健康都有重要影响。这些变化通常是由男性射精的成分引起的，如精子和精液蛋白。然而，由于年龄，交配史或营养状况等因素，男性的射精可能会发生显着变化。因此，雄性的这种差异可能会导致雄性刺激雌性的反应强度发生变化，从而改变两性的适应结果。我们用果蝇（Drosophila melanogaster）测试了雄性状况的三个方面是否会形成一种重要的、但尚未得到充分研究的交配后反应--增加的雌性对雌性的攻击。我们发现，与年长雄性交配的雌性比与年轻雄性交配的雌性更少打架。这种影响加剧了老，性活跃的男性，但没有影响的男性饥饿状态交配引起的女性侵略。年龄和交配史对雌性交配后摄食持续时间也有显著影响，我们的研究结果补充了越来越多的文献，即雄性条件的变化可以通过雌性交配后的反应（包括雌性与雌性的相互作用）来塑造性选择。因此，研究这种变化可能有助于了解性的条件如何影响另一方的行为。
Mating changes female behaviour and physiology across a wide range of taxa, with important effects for male and female fitness. These changes are often induced by components of the male ejaculate, such as sperm and seminal fluid proteins.However, males can vary significantly in their ejaculates, due to factors such as age, mating history, or nutritional status. This male variation may therefore lead to variation in the strength of responses males can stimulate in females, with alterations in fitness outcomes for both sexes.Using the fruit fly,Drosophila melanogaster, we tested whether three aspects of male condition shape an important, but understudied, post-mating response – increased female-female aggression.We found that females mated to old males fought less than females mated to young males. This effect was exacerbated in mates of old, sexually active males, but there was no effect of male starvation status on mating-induced female aggression. There was also a significant effect of age and mating history on female post-mating feeding duration.Our results add to a growing body of literature that variation in male condition can shape sexual selection through post-mating responses in females, including female-female interactions. Studying such variation may therefore be useful for understanding how the condition of sex affects the behaviour of the other.
