Introduction: The digit ratio between the index and the ring finger of the right hand (2D:4D) shows sexual dimorphism and has been proposed as an indirect measure of prenatal androgen exposure. It has been implicated in many gender differences including performance in sports. However, reports in males and females are conflicting. Handgrip strength is a good overall measure of muscle strength and function. Hence, our aim was to study the 2D:4D in males and females and to look for any correlation between 2D:4D and handgrip strength.
Materials and Method: Scanned images of the right hand of young volunteers were analysed and the 2D:4D ratio was calculated. Handgrip strength was measured and results were correlated with 2D:4D.
Result and conclusion: 2D: 4 D ratio of males was significantly less than in females(p<0.001). 2D:4D ratio in males positively correlated with handgrip strength (p<0.05) but not in females.
Keywords: 2D:4D ratio, sexual dimorphism, Hand grip strength
