Men with longer ring finger have bigger testicles – study

A new research has revealed that finger ratios on the right hand of males is an indicator of the size of their testicles.

The study, carried out by South Korean researchers from the Department of Urology at Gachon University Gil Hospital in Incheon and Seoul National University Hospital, found that adult males with a ring finger longer than their index finger on their right hand had larger testicles.

Conversely, men with a longer index finger compared to their ring finger have smaller testicles.
