We bet we can make men look at their hands!

Researchers have discovered men with index and ring fingers close to the same size are more likely than men with mismatched digits to have a long penis.

The odd findings were recently published in the Asian Journal of Andrology after being discovered by a study at Gachon University Gil Hospital in South Korea.

Boffins had recruited 144 volunteers who were undergoing urological surgery and when they were under anaesthesia measured their fingers and penis length (both flaccid and stretched).

It was then found that the smaller the difference between the two fingers, the longer the penis -- stretched penis length correlates to erect size.

But before you start staring at everyone's hands, it's worth noting the average size difference between fingers is just 0.97 cm… obviously ours is much smaller.
