雄性的睾酮依赖性第二性征可能是免疫能力的信号（1），并在几个物种中进行性选择（2，3）。在人类中，女性身体的雌激素依赖性特征与健康和生殖健康相关，并被发现具有吸引力（4-6）。增强人脸的性别二态性应该通过增强女性的青春和生育能力（5，7 -11）以及男性的优势和免疫能力（5，12，13）的性激素相关线索来提高am-activity。在这里，我们报告的结果，要求受试者选择最有吸引力的面孔，从连续性，增强或减少女性和男性的平均形状之间的差异。正如预测的那样，受试者更喜欢女性化的ta，女性面孔的平均形状。这种偏好适用于英国和日本人群，但在人群内的判断中更强，这表明吸引力线索是学习的。受试者更喜欢女性化的平均或男性化的男性面孔形状。增强男性化的面部特征增加了与关系和父亲投资相关的感知优势和负面归因（例如，冷漠或不诚实）。这些结果表明，选择压力，限制性二态性和鼓励幼态持续在人类。
Testosterone-dependent secondary sexual characteristics in males may signal immunological competence(1) and are sexually selected for in several species(2,3). In humans, oestrogen-dependent characteristics of the female body correlate with health and reproductive fitness and are found attractive(4-6). Enhancing the sexual dimorphism of human faces should raise am-activeness by enhancing sex-hormone-related cues to youth and fertility in females(5,7-11), and to dominance and immunocompetence in males(5,12,13). Here we report the results of asking subjects to choose the most attractive faces from continua that enhanced or diminished differences between the average shape of female and male faces. As predicted, subjects preferred feminized ta, average shapes of a female face. This preference applied across UK and Japanese populations but was stronger for within-population judgements, which indicates that attractiveness cues are learned. Subjects preferred feminized to average or masculinized shapes of a male face. Enhancing masculine facial characteristics increased both perceived dominance and negative attributions (for example, coldness or dishonesty) relevant to relationships and paternal investment. These results indicate a selection pressure that limits sexual dimorphism and encourages neoteny in humans.
