Hypothesis
Do women's preferences for masculinity and symmetry in male faces and bodies change across the menstrual cycle?
Conclusion
The study found no evidence for a cyclic shift in female preferences for masculinity and symmetry in male faces and bodies across the menstrual cycle.
Supporting Evidence
- Attractiveness ratings were correlated with independent ratings of masculinity and symmetry.
- There was no significant difference in attractiveness ratings between high- and low-fertility phases.
- Previous studies using computer-generated stimuli found cyclic shifts in preferences, but this study used real photographs.
Takeaway
Women didn't change their preferences for masculine or symmetrical men based on their menstrual cycle, meaning they liked these traits equally at all times.
Methodology
The study used photographs of 117 male faces and bodies, rating them for attractiveness, masculinity, and symmetry by 25 women at high- and low-fertility phases of their menstrual cycle.
Potential Biases
The majority of female raters were in stable relationships, which may influence their preferences.
Limitations
The sample size of female participants was relatively small compared to previous studies, which may limit the generalizability of the findings.
Participant Demographics
Participants were 25 Caucasian females with regular menstrual cycles, aged 23-34 years, 80% of whom were in stable relationships.
