Is early postnatal growth velocity, a proxy of minipubertal androgen action, related to adult second-to-fourth digit (2D:4D) ratios in men? A test in Cebu, Philippines.

We found modest evidence that adult digit ratios relate to an anthropometric correlate of androgen exposure during minipuberty. Definitive assessment of the role of postnatal T in shaping digit ratios will require direct measures of perinatal T related to longitudinally assessed digit ratios.
