在有性繁殖的动物中，射精是健康的基础：雄性通过射精获得所有的直接健康，而雌性则需要射精来繁殖。射精的精子和非精子成分（包括外精子、精液蛋白质、水和大分子）在交配后的性选择和性冲突中都起着至关重要的作用，这一过程可能会导致快速的进化变化和生殖隔离。在这里，我们评估了越来越多的证据，这些证据表明，将射精成分作为一个整体，以及射精成分之间潜在的权衡，对预测男性生殖投资和女性对射精的反应有重要的影响。我们回顾了当前的理论和实证工作，并详细说明了社会和环境对射精成分的影响如何对两性的健康产生潜在的深远影响。
Ejaculates are fundamental to fitness in sexually-reproducing animals: males gain all their direct fitness via the ejaculate and females require ejaculates to reproduce. Both sperm and non-sperm components of the ejaculate (including parasperm, seminal proteins, water and macromolecules) play vital roles in post-copulatory sexual selection and conflict, processes that can potentially drive rapid evolutionary change and reproductive isolation. Here, we assess the increasing evidence that considering ejaculate composition as a whole – and potential trade-offs among ejaculate components – has important consequences for predictions about male reproductive investment and female responses to ejaculates. We review current theory and empirical work, and detail how social and environmental effects on ejaculate composition have potentially far-reaching fitness consequences for both sexes.
