The Relationship Between Second-to-Fourth Digit Ratio and Female Gender Identity

Year Published: 2012

Published In: The Journal of Sexual Medicine

Sample: 37 trans-men, 40 control (20 cis-men, 20 cis women)

Conclusion: "The finger length ratio 2D : 4D in GID-FtM was significantly lower than in female controls in the right hand in this study. 2D : 4D showed a positive correlation with GIS score. Because 2D : 4D influences are assumed to be established in early life and to reflect testosterone exposure, our results suggest a relationship between GID-FtM and perinatal testosterone."
