The royal society has found finally found a link to fetal testosterone exposure and facial masculinization. This long time study measured the prenatal testosterone of many Caucasian men and women, and then took photos of their faces, converted them to 3D models, and using a software analyzed them and found out that prenatal testosterone exposure is indeed correlated to masculine facial features (even more than pubertal testosterone.
Among the diphormism traits they losted: skin tone, IPD (wide set eyes are more masculine) chin prominence, eye size and beard growth.
Reminder this study was done specifically on Caucasian men so no ethnics.
No correlation was found between 2d:4d digit ratio and any of these traits.
