Men with ring fingers that are longer than their index fingers are likely to have been exposed to more testosterone before birth.
The correlation of this digit ratio to prenatal hormone levels has long been common knowledge, but a recent study has taken this information a step further. A recent study published in Discover Magazine claims that women tend to be more attracted to men with higher ring-to-index-finger ratios. Or in other words, the longer the ring finger in comparison to the index, the more attractive a man’s face is rated. A interesting thing to note, however, was that women in the study did not show a preference for smells or voices of these males with longer ring fingers. This implies that such characteristics are more dependant on circulating levels of adult testosterone than levels of the hormone imparted on males while still in the womb.
