The interaction between cortisol and testosterone does not reliably predict men's facial attractiveness or health. While some evidence suggests a link to facial dominance, the overall relationship is not robust.
Area of Science:
- Endocrinology
- Evolutionary Psychology
- Facial Morphology
Background:
- Previous research suggests a link between hormone levels and perceived facial attractiveness.
- Evidence regarding the interaction of cortisol and testosterone in predicting facial attractiveness is inconsistent.
Purpose of the Study:
- To investigate the correlation between men's facial attractiveness and the interaction of cortisol and testosterone levels.
- To examine the relationship between this hormone interaction and perceived facial health and dominance.
Main Methods:
- Correlational analysis was used to assess relationships.
- Men's facial attractiveness, health, and dominance were rated.
- Interactions between cortisol and testosterone levels were analyzed.
Main Results:
- No significant correlation was found between the cortisol-testosterone interaction and facial attractiveness ratings.
- No significant correlation was found between the cortisol-testosterone interaction and facial health ratings.
- A potential link between the hormone interaction and facial dominance was observed, particularly with higher testosterone in men with higher cortisol.
Conclusions:
- The interaction between cortisol and testosterone does not appear to be a robust predictor of men's facial attractiveness or health.
- The interaction may play a role in perceived facial dominance, warranting further investigation.
