Studies indicate that finger length ratios but not the size of the fingers themselves can provide some clue about member length. The Republican debate on 3 March took a turn for the raucous early in the evening, when Donald Trump responded to a jab Marco Rubio had made a few days earlier about the size of his hands :.

Are your index and ring fingers mismatched? Congratulations, you're more likely than men with matching digits to have a long penis. A smaller ratio between the second and fourth fingers is linked to a longer stretched penis size, researchers report today July 4 in the Asian Journal of Andrology. The findings go beyond providing a new finger ratio-based pick-up line for men in bars, however; researchers say that a quick look at a man's fingers could reveal his exposure to male hormones in the womb, providing a hint about his risk for hormone-driven diseases like prostate cancer.

The research team, led by urologist Dr. Tae Beom Kim from Gachon University in Incheon, Korea, measured the fingers and penises -- both stretched-out and flaccid -- of men who were anesthetized before undergoing urological surgery. Men's ring fingers are usually longer than their index fingers. But Kim and colleagues linked a larger gap in finger length -- a lower 2D:4D ratio -- to a longer stretched-out penis. The length of the penis when stretched is believed to correlate to its erect length, the team reported.

Strong, calloused palms suggest that a man works with his hands , spends lots of time outside, or lifts weights. Bruised knuckles may be associated with fighters. And long, dexterous fingers on male hands seem to be common among concert pianists, surgeons, and artists. Turns out, men who are overly concerned about the size of their hands should shift their attention to their fingers.
