Penis size linked to finger length

Penis and finger lengthThe longer a man’s ring finger when compared with his index finger, the longer the length of his penis, according to Korean researchers.

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 144 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.

“Based on this evidence, we suggest that digit ratio can predict adult penile size, and that the effects of prenatal testosterone may in part explain the differences in adult penile length,” the researchers reported Monday in the Asian Journal of Andrology.

  1. I kept waiting for the “While you are reading this part of the article, 90% of men are still trying to measure their ring and index fingers” punchline.

  2. Well Sander, the guy interpreting the story didn’t get past the first couple of sentences, measured his fingers, and confidently reported his…I mean their…findings.
