Melbourne: Men, who have shorter index fingers, as compared to their ring fingers may have longer penises, a new research has revealed.
Korean scientists studied 144 men and discovered that the ratio between their second and fourth fingers - known as digit ratio - is linked to stretched penile length, reports a daily.
They discovered that while each man`s height, ring finger length and digit ratio were all associated with the size of his penis, the digit ratio was the sole "significant predictive factor" for stretched penile length.
The lower the ratio, the study suggests, the longer the penis may be.
According to the team, digit ratio "has been correlated with a number of aspects of reproductive biology and sexual behaviour over the past decade, including a link with the risk of developing prostate cancer".
