先前的研究报道了女性的外表，配偶偏好，额外和配对性欲和行为的排卵变化。但因样本量小、设计不当和分析中未公开的灵活性而受到批评。在本研究中，我们试图通过预先登记我们的假设和分析计划，并通过收集大量的日记样本来解决这些批评。我们以日记的形式收集了1,054名女性的26,000多份可用的在线自我报告，其中429人自然骑自行车。我们从月经开始的报告中推断出了生育期。我们使用激素避孕药作为准对照组，因为他们经历月经，但不排卵。我们探讨了我们的结果对不同方法的稳健性（包括不同的生育率估计，不同的排除标准，调整潜在的混淆，方法因素的调节）。我们发现了强有力的证据支持先前报道的排卵增加的额外配对的欲望和行为，配对的欲望，和自我感知的愿望，以及没有意外的关联。然而，我们没有发现预测的影响伴侣伴侣保留行为，服装选择，或自恋。与一些早期的文献相反，伴侣的性吸引力并没有缓和周期的变化。总之，现有文献关于排卵变化的可重复性是混合的。最后，我们基于模拟的建议，阅读过去的文献和设计未来的大规模预注册的受试者内的研究，以了解排卵周期的变化和激素避孕的影响。排卵变化大小的个体间差异是进一步研究的重要领域。
Previous research reported ovulatory changes in women's appearance, mate preferences, extra- and in-pair sexual desire, and behavior. but has been criticized for small sample sizes, inappropriate designs, and undisclosed flexibility in analyses. In the present study, we sought to address these criticisms by preregistering our hypotheses and analysis plan and by collecting a large diary sample. We gathered more than 26,000 usable online self-reports in a diary format from 1,054 women, of which 429 were naturally cycling. We inferred the fertile period from menstrual onset reports. We used hormonal contraceptive users as a quasi-control group, as they experience menstruation, but not ovulation. We probed our results for robustness to different approaches (including different fertility estimates, different exclusion criteria, adjusting for potential confounds, moderation by methodological factors). We found robust evidence supporting previously reported ovulatory increases in extra-pair desire and behavior, in-pair desire, and self-perceived desirability, as well as no unexpected associations. Yet, we did not find predicted effects on partner mate retention behavior, clothing choices, or narcissism. Contrary to some of the earlier literature, partners' sexual attractiveness did not moderate the cycle shifts. Taken together, the replicability of the existing literature on ovulatory changes was mixed. We conclude with simulation-based recommendations for reading the past literature and for designing future large-scale preregistered within-subject studies to understand ovulatory cycle changes and the effects of hormonal contraception. Interindividual differences in the size of ovulatory changes emerge as an important area for further study.
