In this cross-sectional study, 156 university students (85 females, 71 males) aged 18-30 were included. Handgrip strength, a marker of physical performance, was measured using a digital dynamometer following the standardized protocol recommended by the American Society of Hand Therapists. Finger lengths were assessed with a digital caliper, and the 2D:4D ratio was calculated accordingly. The study revealed moderate positive correlations between hand grip strength and the lengths of both the right fourth digit and the left fourth digit, as well as a weak correlation with the left second digit length in male participants. No statistically significant associations were found between 2D:4D ratios and handgrip strength on either hand. The findings suggest that prenatal hormonal influences may shape both morphological (2D:4D ratio) and functional (handgrip strength) outcomes, with potential implications for physical performance traits.
