精子竞争可能会选择影响雌性交配或产卵率的雄性生殖特征。这些特征可能会给女性带来健康成本；然而，它们对于男性来说可能代价高昂，而且女性健康状况的任何下降也会影响男性健康状况。雄性对精子竞争的适应不仅通过改变雌性的行为或生理，而且还改变雌性的形态来操纵雌性。在球织蜘蛛中，交配可能需要破坏雌性生殖器的外部结构，这会阻止与后续雄性的生殖器交配。在这里，我们提出了一个博弈论模型，表明即使在切割成本相对较高的情况下，女性外阴残割也受到青睐，并且每个女性和最后一个男性精子优先级的大量交配遭遇都有利于它。
Sperm competition may select for male reproductive traits that influence female mating or oviposition rate. These traits may induce fitness costs to the female; however, they may be costly for the males as well as any decrease in female fitness also affects male fitness. Male adaptations to sperm competition manipulate females by altering not only female behaviour or physiology, but also female morphology. In orb-weaving spiders, mating may entail mutilation of external structures of the female genitalia, which prevents genital coupling with subsequent males. Here, we present a game theoretical model showing that external female genital mutilation is favoured even under relatively high costs of mutilation, and that it is favoured by a high number of mate encounters per female and last-male sperm precedence.
