South Korean researchers, at Gachon University Gil Hospital, published a study, in the Daily Telegraph, revealing that men, whose right-hand ring-finger is longer than the pointer finger, are relatively more susceptible to prostate cancer, than men with a ring-finger shorter than the pointer finger.

This study was triggered by an earlier research that proved that the length of the ring-finger in men is directly proportional with the amount of testosterone a male embryo is subjected to inside the womb.

Scientists in Incheon, South Korea utilized this study to go through the prospects of men developing prostate cancer. 366 men of those, who were hospitalized before for showing signs of prostate cancer, took part in the research. All the men were over their 40s and they all fit the criterion of a relatively longer ring-finger in their right hand.

The research resulted in statistics showing that men with longer ring-finger have 50% more prostate specific antigen (PSA) in their blood, than men with shorter ring finger, indicating that these men were 3 times more likely to be diagnosed with prostate cancer than other "normal" men.

On the other hand, the study also showed that, even though they might have a higher risk of prostate cancer, men with relatively long ring finger develop more immunity against heart diseases than those with a shorter ring finger. These men are also proved to be highly fertile.
