A man’s fingers can reveal his fertility. A study carried out by South Korean researchers from the Department of Urology at Gachon University Gil Hospital in Incheon in collaboration with Seoul National University Hospital has concluded that the arrangement and length of fingers on a man’s hand can tell how ‘endowed’ one is.
Reported on Mail Online, the study found that adult males with ring fingers longer than their index fingers on their right hands had larger testicles.
Conversely, men with longer index fingers compared to their ring fingers were found to have smaller testicles. The study established that the size of testicles was proportional to the ability of a man to sire children.
