Faces of men with high serum testosterone are less attractive for women during the fertility phase of the menstrual cycle
The attractiveness of the human face plays an essential role in mating as it may signal the genetic suitability of a mate. The controversial ‘ovulatory shift hypothesis’ postulates that women in the fertile phase of the menstrual cycle would prefer faces of masculine men with high testosterone...
We have shown that images of faces of males with high concentration of circulating testosterone were rated as significantly less attractive by young women, on 13th fertile day of their menstrual cycle.
Using advanced Bayesian multilevel modeling we showed that the attractiveness of men’s faces is significantly lower in men with a high concentration of serum total testosterone, even taking into account the concentration of serum estrogen in the raters.
Figure A is pure cagefuel and proves that (again) attractiveness is not normative.

Looks like TAILS is right JFL.![]()
The images of a composite face of all 77 men (a), of 39 men scored as more attractive than median (b), and of 38 men scored as less attractive than median (c) by 19 female raters. Note that compared to the attractive one the less attractive composite face is slightly bigger and was scored on average by 1.93 points lower. The men from the attractive group had lower testosterone concentration than from the less attractive group.
Proof that women have domesticated men JFL.Accelerated natural selection against aggression in the last 200,000 years coincided with the further feminization of human faces as evidenced by a reduction in brow ridge projections and a shortening of the upper facial region most likely due to reduction in androgen activity on craniofacial structures [63, 67, 68]. Given that testosterone is linked to dominance, egoistic choices, aggressive and unfaithful behavior in men, the feminization of male faces may indicate preferential selection for increased social tolerance that allowed humans to work more productively [66, 69, 70]. Thus, declining androgen effects most likely “domesticated” and shrunk the human face and body size.
