When mos likely to become impregnated female humans are more attracted to traditionally masculine traits.
Female hormones impact women’s assertiveness and sexual availability, according to a study recently published in Psychoneuroendocrinology.
Previous studies of female sexual behavior have found that women are the fussier sex when it comes to mate selection. This is thought to be because women put in the greater parental investment due to pregnancy, giving birth, breast feeding and historically being the primary carer for the offspring, whilst the male took on a hunter-gatherer role. Therefore, females are more selective in choosing a high quality mate that compensates for their parental investment.
