Proven Study
A study in Scotland showed that the kind of "male face" a woman finds attractive can differ depending on where a woman is in her menstrual cycle. For instance, if she is post-menstrual she may be attracted to plain facial features. When pre-menstrual she can be attracted to more feminine features in a man. If she is ovulating she is attracted to men with rugged, masculine features, and if she is menstruating she is more prone to be attracted to a man with a pair of scissors shoved in his temple.
