Hold your breath no longer. The rumors about finger length and penis size are accurate. According to this article, a recent South Korean study found that men with a low index-to-ring finger ratio had a longer penis, both flaccid and when stretched.

The study, published July 4 in the Asian Journal of Andrology, consisted of 144 Korean men aged 20 and up, all of whom were in preparation for urological surgery. Researchers measured the index and ring fingers of each man’s hands in comparison with each man’s flaccid and stretched penis.

What they found may very well put to rest all those rumours you’ve heard about finger and penis length since childhood. A low index-to-ring finger ratio on the right hand indicated a longer penis. The longer the ring finger in relation to the index, the longer the penis.

While the length of each man’s erect penis showed a strong correlation to the length of the penis in flaccid and stretched state, finger length did not predict the length of an erection.

The researchers note that penis length appears to be determined in the womb. As the fetus develops, it absorbs a common set of genes, including testosterone, that influence both limb development and the urogenital system. That in turn determines length of, you guessed it, your Johnson.

And notably, the men with a higher index-to-ring finger ratio (in which the index finger was closer in length or longer than the ring finger) on their right hand had a shorter penis.

No word on the left hand.

Though the findings seem trivial, the researchers believe that the study results may help to treat clinical conditions related to male development.

And it’s a cool way to break the ice at cocktail parties.
