There has been a recent burst of studies of the function of genitalia, many of which share several important shortcomings. Given that further studies on this topic are likely (there are probably millions of species showing rapid genital divergence), I discuss the studies critically to promote clear formulation of hypotheses and interpretation of results in the future. I also emphasize some possibly important but neglected variables, including female stimulation, phylogenetic contexts, and the behavior of male genitalia, and outline simple techniques that could improve future studies.
最近有大量关于生殖器功能的研究，其中许多研究都存在几个重要的缺陷。考虑到这个话题的进一步研究会很有必要（可能有上百万个物种都在快速进化它们的生殖器），我批判性地讨论了这些研究，以促进未来清晰地提出假设和解释结果。我还强调了一些可能很重要但被忽视的变量，包括雌性刺激、系统发育背景和雄性生殖器的行为，并概述了一些可以改进未来研究的简单技术。
