There is another measurement for men that involves a body part without bone structure.
Perhaps this report settles once and for all, what proportion of normally more visible measurements are true correlates with that measurement.

According to the literature (RIP my search history), height is weakly correlated with it [1], while the ratio between the second digit and fourth digit is moderately correlated [2]. Weirdly enough, the 2D:4D ratio has to do with bone lengths, but is still correlated with that measurement.
