A team of South Korean researchers led by Tae Beom Kim of Gachon University in Incheon, may have come up with answers in predicting penis length in a recent study published in the Asian Journal of Andrology, globalpost said.
The team investigated 144 men to find out “why men who undergo normal puberty have different penile lengths'' and came up with a surprising conclusion; men’s index finger (also referred to as the forefinger, pointer finger, trigger finger, etc.) tend to be shorter than their ring finger, giving a lower digit ratio… “the lower the ratio of the lengths of the two fingers, the longer the penis was in its stretched state.”
Other findings related to the two fingers revealed men with a lower ratio have a more symmetrical face and are more attractive to women, a phenomenon that has been referred to as ‘sexy ratio,’ Los Angeles Times said.
And researchers at Warwick University and the Institute of Cancer Research in Britain reported that men whose index fingers were longer than their ring fingers were found to be one-third less likely to develop prostate cancer.
