We investigated women's facial attractiveness and body shape as a function of menstrual cycle phase, with the expectation from previous research that both would be enhanced during the high fertile phase. To control for the effects of women's daily behaviors on their appearance and waistline, we visited 37 normally cycling women twice in their dorm, where we photographed and measured them at low and high fertile days of their cycle immediately upon their waking. Seventy-four judges from a separate institution chose, for each woman, the picture they thought was more attractive. We analyzed a subset of 20 women who, by forward counting, had a High Fertility visit between Days 10-13 and a Low Fertility visit between Days 20-23; and we also analyzed a subsample of 17 women who, by reverse counting, had a High Fertility visit on the days leading to ovulation and a Low Fertility visit one week after ovulation. In neither set of analyses were women's waist- to-hip ratios lower nearer ovulation, and in neither set were women's high fertile pictures chosen at an above-chance rate by either male or female judges. We did not find evidence that facial attractiveness and waist-to-hip ratio are reliable physical cues of ovulatory status.
我们研究了女性面部吸引力和体型与月经周期阶段的关系，基于先前研究预期二者在高生育力阶段都会增强。为控制女性日常行为对其外貌和腰围的影响，我们在37名月经周期正常的女性宿舍对她们进行了两次访问，在她们周期的高生育力日和低生育力日醒来后立即对其进行拍照和测量。来自另一个机构的74名评判员为每位女性选出他们认为更有吸引力的照片。我们分析了一个由20名女性组成的子集，通过顺数法，她们在第10 - 13天有一次高生育力访问，在第20 - 23天有一次低生育力访问；我们还分析了一个由17名女性组成的子样本，通过倒数法，她们在排卵前几天有一次高生育力访问，在排卵一周后有一次低生育力访问。在这两组分析中，接近排卵期时女性的腰臀比都没有更低，而且在这两组分析中，男性或女性评判员选择女性高生育力照片的比例都未高于随机概率。我们没有找到证据表明面部吸引力和腰臀比是排卵状态的可靠身体线索。
