Attractiveness, body size, masculine sex roles and 2D:4D ratios in men

Several studies have examined men’s attractiveness in relation to the index-to-ring-finger (2D:4D) ratio, which may be linked to prenatal androgen levels. These studies have yielded conflicting results and have not controlled for related characteristics (i.e., body size and masculine personality/sex role). The present study again examined this relation and attempted to address these limitations. Participants were 273 men recruited at university. The men were assessed for physical attractiveness (both self-perceived and other-rated), body size (height, BMI), 2D:4D ratios and masculine personality/sex roles. Results showed that masculine personality/sex role and height predicted men’s attractiveness. Results also indicated that a low (more masculine) 2D:4D ratio in the right hand was related to men’s attractiveness. This relationship occurred controlling for body size and personality/sex roles, along with relevant demographics. The findings suggest that women may be partially attracted to men because of their relative level of prenatal androgen exposure; and that features of physical attractiveness in men are, at least partly, androgen-based markers of fitness detectable by women.
