Understanding how male and female fitness evolve requires anunderstanding of how they are linked. Males and females sharemost of their genome, so selection on one sex is likely to haveconsequences for the other. If selection acts upon sexuallydimorphic traits with a shared developmental/genetic basis (e.g.gonadal function), these consequences may be substantial bothat the genotypic and phenotypic level (Rogers et al. 2020).In birds, selection for egg production induces large changes tothe oviduct. Male and female gonads differentiate from thesame tissue, so correlated responses in the testes are likely.Pick et al. (2017) recently demonstrated that artificial selectionfor female reproductive investment affects reproductive successin males . It is not yet known whether sex-specific selectioninfluences ejaculate traits (e.g. sperm function), or how this islinked to testis morphology.

了解男性和女性的健康是如何进化的，需要了解他们是如何联系的。雄性和雌性的基因组大部分是相同的，所以对一种性别的选择很可能会对另一种性别产生影响。如果选择作用于具有共同发育/遗传基础（例如性腺功能）的性二态性状，则这些后果可能在基因型和表型水平上都是实质性的（Rogers et al. 2020）。男性和女性的性腺从相同的组织中分化出来，因此睾丸中的相关反应是可能的。Pick et al.（2017）最近证明了女性生殖投资的人工选择会影响男性的生殖成功。目前尚不清楚性别特异性选择是否影响射精特征（例如精子功能），或者这与睾丸形态如何相关。
