This cross-sectional study investigates the relationship of aggression and second-to-fourth digit ratio (2D:4D) among randomly selected second year medical students of DLSHSI. Ninety (90) male and ninety-four (94) female respondents aged 18-26 were assessed to determine the relationship between aggression, assessed using the Buss and Perry Aggression Questionnaire, and second-to-fourth digit ration (2D:4D), taken from digital measurement of hand scans. There was no association found between 2D:4D and BPAQ scores upon Pearson correlation coefficient analysis. It was found that there was a significant difference in the level of physical aggression in both genders but no significant difference in level of aggression of males and females in terms of physical, verbal, hostility, and anger traits as well as the total level of aggression. It was also noted that left and right 2D:4D was significantly different among the genders (p=0.0003;0.004).
