Guys, you might never look at your fingers the same way. A new study from South Korean researchers at the Department of Urology at Seoul National University Hospital and Gachon University Gil Hospital shows that the length of your ring finger finger compared to your index finger on your right hand is an indicator of testicle size.

The study covered 172 Korean men aged 20-69, and it showed that if your ring finger was longer than your index finger on your right hand, chances are that you have bigger testicles. The study worked by measuring each person's second and fourth fingers and then separately measuring their testicles.
