Recent research has revealed that many aspects of female sexuality change across the menstrual cycle. In this study, we examined changes in sexual fantasies and visual sexual interests across the menstrual cycle. A total of 27 single, heterosexual women (M age=21.5 years) not using hormonal contraceptives answered questions on a web-based diary every day for 30 days about their sexual fantasies and behaviors. Twenty-two of them also completed a viewing time task during three different menstrual cycle phases (follicular, ovulation, and luteal) to assess changes in visual sexual interest. Ovulation status was determined by a self-administered urine test. Results showed that the frequency and arousability of sexual fantasies increased significantly at ovulation. The number of males in the fantasies increased during the most fertile period, with no such change for the number of females. Fantasy content became more female-like during ovulation, focusing more on emotions rather than explicit sexual content. Women displayed a category non-specific pattern of viewing time with regard to target age and gender, regardless of fertility status. Results were discussed in the context of the ovulatory shift hypothesis of female sexuality.
最近的研究揭示，女性的性特征在整个月经周期中会发生多个方面的变化。在这项研究中，我们考察了性幻想和视觉性兴趣在月经周期中的变化。共有 27 名未使用激素避孕药的单身、异性恋女性（M 年龄=21.5 岁）在 30 天内每天通过在线日记回答有关性幻想和行为的问题。其中 22 人还在三个不同的月经周期阶段（卵泡期、排卵期和黄体期）完成了观看时间任务，以评估视觉性兴趣的变化。排卵状态通过自我管理的尿液测试确定。结果表明，性幻想的频率和唤起程度在排卵期显著增加。在最肥沃的时期，幻想中的男性数量增加，而女性数量没有变化。在排卵期，幻想内容变得更加女性化，更多地关注情感而非明确的性内容。无论生育状态如何，女性在观看时间方面表现出非特定类别的模式，与目标年龄和性别无关。结果在女性性行为的排卵转移假说的背景下进行了讨论。
