In this paper, I consider the criteria necessary to demonstrate the postcopulatory ability of females to favor the sperm of one conspecific male over another, that is, sperm choice. In practice it is difficult to distinguish between sperm competition and sperm choice, and sperm choice can be demonstrated only if the effects of sperm competition can be controlled. Few studies have used experimental protocols that do this, so evidence for sperm choice is limited. Moreover, in those studies in which sperm choice occurs, it does so to avoid incompatible genetic combinations and is therefore unlikely to result in directional sexual selection.
在本文中，我探讨了证明雌性在交配后有能力偏好一个同种雄性的精子而非另一个同种雄性的精子（即精子选择）所需的标准。在实际中，很难区分精子竞争和精子选择，并且只有在能够控制精子竞争的影响时，才能证明存在精子选择。很少有研究采用能做到这一点的实验方案，因此精子选择的证据有限。此外，在那些存在精子选择的研究中，其发生是为了避免不相容的基因组合，所以不太可能导致定向性选择。
