2D:4D Ratio

Apparently the ratio of the index finger length to the ring finger length indicates the exposure a baby has to testosterone while in the womb. Lesser the ratio, longer the ring finger, more masculine is the baby. https://www.livescience.com/49883-finger-length-in-men.html.

Seems like what WHR is for women, 2D:HD is for men.
