Roosh's lab-bound scientist counterparts corroborate #2 of the "9 Immutable Laws of Pick up":

"Women subconsciously prefer the aroma of dominant men when they are at the most fertile stage of the menstrual cycle, research suggests... Those who were ovulating rated the "dominant" men as sexiest, but there was no similar pattern among women at other stages of their menstrual cycle. The findings, published in Biology Letters, suggest women are evolved to seek out the most virile sexual partner when conception is likely. But the rest of the time they probably prefer potential social partners." (source: The BBC)

Another one... (i especially like the part about "fooling the male visual system"):

Women with high levels of the sex hormone oestrogen have prettier faces, research suggests.
The findings make evolutionary sense - men are attracted to the most fertile women, the University of St Andrews team told a Royal Society journal
"Head of the study, Miriam Law Smith, said: "Women are effectively advertising their general fertility with their faces.
"Make-up can improve appearance across the board, but it will obviously help people who are less attractive more."
For example, eye make-up can be used to make the eyes appear bigger and foundation can make the skin look clearer.
"Our findings could explain why men universally seem to prefer feminine women's faces.
"In evolutionary terms, it makes sense for men to favour feminine fertile women - those that did would have had more babies," she added.
Dr Tony Little, a lecturer in the School of Biological Sciences at the University of Liverpool, said: "It's a very interesting study.
"The findings make sense. There are clear benefits to choosing particular types of female faces. Oestrogen is related to fertility.
"The findings about make-up are also interesting. The implication is that women are employing a deceptive strategy. They can fool the male visual system with make-up."
