Are ovulatory cycle shifts in women's mate attraction and preferences robust? What are underlying mechanisms of potential cycle shifts? These questions are the subject of a current scientific debate surrounding the good genes ovulatory shift hypothesis. Here, we report a large, preregistered, within-subjects study, including salivary hormone measures and conception risk estimates based on luteinizing hormone tests. In four sessions across one ovulatory cycle, N = 257 women (= 1028 sessions) rated the attractiveness of 40 natural male bodies, 40 natural female bodies and 40 objects. Multilevel analyses yielded weak evidence for ovulatory increases in women's general attraction, specifically to male bodies, though they are not systematically related to changes in steroid hormone levels. Further, we found no compelling robust evidence for mate preference shifts across the cycle, as only one out of many different tests showed some weak evidence for such effects. Mechanisms regulating cycle shifts, the impact of our results on developing and revising cycle shift theories, and influences of different methodologies on results are discussed.

女性对配偶的吸引力和偏好的排卵周期变化是否稳健？潜在周期变化的潜在机制是什么？这些问题是当前围绕良好基因排卵转移假说进行的科学辩论的主题。在这里，我们报告了一项大型、预先注册的受试者内研究，包括基于促黄体激素测试的唾液激素测量和受孕风险估计。在一个排卵周期的四次会议中，N= 257 名女性（= 1028 次）对 40 个自然男性身体、40 个自然女性身体和 40 个物体的吸引力进行了评分。多层次分析得出了女性总体吸引力增加的微弱证据，特别是对男性身体的吸引力，尽管它们与类固醇激素水平的变化没有系统地相关。此外，我们没有发现在整个周期中配偶偏好变化的有力证据，因为许多不同的测试中只有一个显示出这种影响的一些微弱证据。讨论了调节周期偏移的机制，我们的结果对发展和修改周期偏移理论的影响，以及不同方法论对结果的影响。
