Studies about women and dating preferences
This finding has been found to hold across different cultures.
It has been argued that masculine facial dimorphism (in men) and symmetry in faces are signals advertising genetic quality in potential mates.
Symmetrical faces and bodies may be signs of good inheritance to women of child-bearing age seeking to create healthy offspring.
Studies suggest women are less attracted to men with asymmetrical faces, Since achieving symmetry is a difficult task during human growth, requiring billions of cell reproductions while maintaining a parallel structure, achieving symmetry is a visible signal of genetic health.
Women, on average, tend to be attracted to men who are taller than they are and who display a high degree of facial symmetry, masculine facial dimorphism, and who have broad shoulders, a relatively narrow waist, and a V-shaped torso.
One study called into question the importance of facial masculinity in physical attractiveness in men arguing that when perceived health, which is factored into facial masculinity, is discounted it makes little difference in physical attractiveness.
A study found that the same genetic factors cause facial masculinity in both males and females such that a male with a more masculine face would likely have a sister with a more masculine face due to the siblings having shared genes.
The study also found that, although female faces that were more feminine were judged to be more attractive, there was no association between male facial masculinity and male facial attractiveness for female judges.
With these findings, the study reasoned that if a woman were to reproduce with a man with a more masculine face, then her daughters would also inherit a more masculine face, making the daughters less attractive.

Studies have also suggested that women at peak fertility were more likely to fantasize about men with greater facial symmetry, and other studies have found that male symmetry was the only factor that could significantly predict the likelihood of a woman experiencing orgasm during sex.
