以往的研究表明，雌性黑腹果蝇通过交配受到其配偶的伤害。在这里，我们证明了男性对女性造成的伤害随着男性的体型而增加。具体而言，女性的寿命和产卵率显着下降，作为增加其配偶的身体大小的函数。因此，女性交配较大的男性有较低的终身健身。雄性体型对雌性寿命的不利影响并不通过雄性对雌性生殖力、产蛋率或雌性再交配行为的影响来介导。同样，男性的大小对女性一生的生殖力的影响是独立的男性大小对女性寿命的影响。女性的体型和女性对男性伤害的抵抗力之间没有关系。因此，虽然增加男性的身体大小是已知的，以提高男性交配成功，它有一个不利的影响，直接健身的配偶。我们的研究结果表明，这种伤害是一个多效性的影响，其他一些选定的功能，而不是适应。在某种程度上，雌性更喜欢与体型较大的雄性交配，这种选择是有害的，这种模式与性对抗共同进化理论相一致。
Previous studies indicate that female Drosophila melanogaster are harmed by their mates through copulation. Here, we demonstrate that the harm that males inflict upon females increases with male size. Specifically, both the lifespan and egg–production rate of females decreased significantly as an increasing function of the body size of their mates. Consequently, females mating with larger males had lower lifetime fitness. The detrimental effect of male size on female longevity was not mediated by male effects on female fecundity, egg–production rate or female–remating behaviour. Similarly, the influence of male size on female lifetime fecundity was independent of the male–size effect on female longevity. There was no relationship between female size and female resistance to male harm. Thus, although increasing male body size is known to enhance male mating success, it has a detrimental effect on the direct fitness of their mates. Our results indicate that this harm is a pleiotropic effect of some other selected function and not an adaptation. To the extent that females prefer to mate with larger males, this choice is harmful, a pattern that is consistent with the theory of sexually antagonistic coevolution.
