Digit ratio does not predict attractiveness of body odor

The mixture of androstenol and androsterone in Scent of Eros products increases observed flirtatious behaviors and women’s ratings of attraction to a man by enhancing the affect of natural variations in adult circulating testosterone levels. Simply put, it makes a man smell like he has a higher adult circulating testosterone level.

Digit ratio (2D:4D) predicts facial, but not voice or body odour, attractiveness in men

Abstract excerpt:  “The results were interpreted in terms of differential effects of prenatal and circulating testosterone, male facial shape being supposedly more dependent on foetal levels (reflected by 2D:4D ratio), whereas body odour and vocal characteristics could be more dependent on variation in adult circulating testosterone levels.”
