Abstract

Objective: The present study aimed to compare the 2nd finger to 4th finger ratio (2D:4D) of patients with antisocial personality disorder to the 2D:4D of a group of healthy subjects.


Method: A total of thirty one male patients with antisocial personality disorder and the twenty-eight healthy controls were included in the present investigation. Finger (2D) and ring (4D) lengths and 2D:4D ratio of the subjects were determined.


Results: In the present study, we found that patients with antisocial personality disorder had a significantly lower ratio of 2D:4D of both hands.


Conclusion: In conclusion, we suggest that patients with antisocial personality seem to have a lower ratio of 2D:4D compared to healthy control subjects, leading us to think that higher prenatal gonadal androgens may be related to antisocial personality disorder.
