Physical attractiveness has been shown to reflect women's current fecundity level, allowing a man to choose a potentially more fertile partner in mate choice context. However, women vary not only in terms of fecundity level at reproductive age but also in reproductive longevity, both influencing a couple's long-term reproductive success. Thus, men should choose their potential partner not only based on cues of current fecundity but also on cues of reproductive longevity, and both may be reflected in women's appearance. In this study, we investigated if a woman's facial attractiveness at reproductive age reflects anti-Müllerian hormone (AMH) level, a hormone predictor of age at menopause, similarly as it reflects current fecundity level, estimated with estradiol level (E2). Face photographs of 183 healthy women (Mage = 28.49, SDage = 2.38), recruited between 2nd - 4th day of the menstrual cycle, were assessed by men in terms of attractiveness. Women's health status was evaluated based on C-reactive protein level and biochemical blood test. Serum AMH and E2 were measured. The results showed that facial attractiveness was negatively correlated with AMH level, a hormone indicator of expected age at menopause, and positively with E2, indicator of current fecundity level, also when controlled for potential covariates (testosterone, BMI, age). This might result from biological trade-off between high fecundity and the length of reproductive lifespan in women and greater adaptive importance of high fecundity at reproductive age compared to the length of reproductive lifespan.
外貌吸引力已被证明反映了女性当前的生育能力水平,使男性能够在配偶选择的背景下选择一个潜在更具生育能力的伴侣。然而,女性不仅在生育年龄的生育能力水平上存在差异,而且在生殖寿命上也存在差异,这两个因素都影响着夫妻的长期生殖成功。因此,男性在选择潜在伴侣时不仅应该基于当前生育能力的线索,还应该基于生殖寿命的线索,而这些线索可能都反映在女性的外貌上。在这项研究中,我们调查了女性在生育年龄的面部吸引力是否反映了抗苗勒管激素 (AMH) 水平,AMH 是绝经年龄的激素预测指标,与雌激素水平 (E2) 反映当前生育能力水平的方式相似。我们招募了 183 名健康女性(Mage = 28.49,SDage = 2.38),在月经周期的第 2-4 天,让男性对她们的面部吸引力进行评估。根据 C 反应蛋白水平和生化血液测试来评估女性的健康状况。测量了血清 AMH 和 E2。结果表明,面部吸引力与 AMH 水平呈负相关,AMH 是绝经年龄的激素指标,与 E2 呈正相关,E2 是当前生育能力水平的指标,即使在控制了潜在的协变量(睾酮、BMI、年龄)后也是如此。这可能是由于女性高生育能力和生殖寿命之间的生物学权衡,以及在生殖年龄时高生育能力相对于生殖寿命的更大适应性重要性所致。
