Does size matter? A new finding shows evidence of a link between the relative length of a man’s index and ring fingers and a way to predict the length of his penis. Asian scientists have found that the ratio between the second and fourth digits on a man’s right hand seemed to correlate to the length of his flaccid and stretched penis, with a lower index to ring finger length ratio indicating a longer penis. Over the past decade, the correlation of digit ratio with sexual behavior and other aspects of reproductive biology have been well documented and there is a growing list of traits with links to digit ratio, although the associations are less well established.
