50年前，杰夫·帕克（Geoff Parker）将精子竞争定义为来自两个或多个雄性的精子在使一组卵子受精方面的竞争。自从他那篇具有重大影响的论文发表以来，精子竞争已经发展成为一个庞大的研究领域，并且许多方面仍在不断被发现。其中一个相对了解较少的方面是雄性射精内精子之间选择和竞争的重要性。雄性射精中存在的精子数量之多表明，同一雄性产生的同胞精子之间的竞争可能很激烈。在这篇综述中，我们总结了帕克的理论模型，这些模型对在单倍体配子而非二倍体雄性控制下的精子特征的进化做出了预测。我们回顾了来自众多领域和分类群的射精内竞争的现有证据。我们还讨论了我们在研究射精内精子竞争时所面临的概念和实际障碍，以及新技术如何有助于解决一些目前尚未解决的问题。
本文是“精子竞争50年”主题专刊的一部分。
Sperm competition was defined by Geoff Parker 50 years ago as the competition between sperm from two or more males over the fertilization of a set of eggs. Since the publication of his seminal paper, sperm competition has developed into a large field of research, and many aspects are still being discovered. One of the relatively poorly understood aspects is the importance of selection and competition among sperm within the ejaculate of a male. The sheer number of sperm present in a male's ejaculate suggests that the competition among sibling sperm produced by the same male may be intense. In this review, we summarize Parker's theoretical models generating predictions about the evolution of sperm traits under the control of the haploid gamete as opposed to the diploid male. We review the existing evidence of within-ejaculate competition from a wide range of fields and taxa. We also discuss the conceptual and practical hurdles we have been facing to study within-ejaculate sperm competition, and how novel technologies may help in addressing some of the currently open questions. This article is part of the theme issue ‘Fifty years of sperm competition’.
