Sex biases in immunity have generated much interest because of their possible connection with sex differences in reproductive strategies. Researchers have often argued that males should invest less in immunity than should females. In a recent paper, Stoehr and Kokko challenge this reasonably substantiated view of 'susceptible males'. Their model, and another by Medley, helps highlight relevant tests that could explain other important sources of within-species variation in immunity and its importance to parasitism.
免疫中的性别偏见引发了诸多关注，因为它们可能与生殖策略中的性别差异存在关联。研究人员常常认为，雄性在免疫方面的投入应少于雌性。在最近的一篇论文中，斯托尔和科科对这种有合理依据支持的“易感雄性”观点提出了质疑。他们的模型以及梅德利提出的另一个模型，有助于突出一些相关测试，这些测试可以解释物种内部免疫变异的其他重要来源及其对寄生现象的重要性。
