The ratio of the second to fourth digits (2D:4D) is believed to be a marker of prenatal androgen exposure. Among the many hypotheses for melanocyte loss, one is that sex hormones may play a role in the development of vitiligo. In this study, we aimed to investigate a possible relationship between vitiligo and 2D:4D ratios.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>The participants in this study were healthy volunteers and patients with vitiligo. This study included 100 patients with vitiligo and 110 healthy controls. An electronic Vernier caliper was employed to measure the finger lengths.

The mean age of patients with vitiligo was 27.000\u2009\u00b1\u200913.000\u2009years for females and 30.612\u2009\u00b1\u20099.112\u2009years for males, and the study sample included 54 (49.09%) females and 56 (50.91%) male patients. Patients' 2D:4D ratios were significantly lower than those of the controls for right hands (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.0001). For left hands, there was no correlation between the 2D:4D ratio (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.740). There was no statistically significant correlation between the VETI score and the 2D\/4D ratio (left hand, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.136; right hand <jats:italic>p<\/jats:italic>\u00a0=\u00a00.329).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>To our knowledge, this is the first study to look at the link between 2D:4D ratios and vitiligo in the literature.
