Digit Length Ratio as an Indicator of Fetal Androgen Levels: Relationship to Prostate Volume‐Related Men Lower Urinary Tract Symptoms

Our study demonstrates that the 2D:4D ratio is a straightforward and effective tool for assessing BPH patients, as it correlates with the severity of LUTS symptoms. This non-invasive measure offers potential value in evaluating LUTS, and with age standardization, it could be applied more broadly across age groups. Further large-scale studies are needed to refine its standardization and expand upon current findings.
