I have a couple questions about the facial feature differences between the sexes and why those come to be. There seem to be some facial features that only men have.

1) Do women ever get those big square chins and jaws? Obviously there are women with square faces and some with square jaws like Angie Harmon. A square face is not inherently masculine. But I've never seen a woman with a chin/jaw like Kurt Cobain or Jay Leno.

2) do all men have a brow ridge? I've never seen a woman that had one or a man that didn't have one, that I've noticed. Some are very prominent and others are less noticeable but still there.

As a lay person my research has just told me the difference boils down to testosterone but it must be more than that right? Women do not sprout these features from taking testosterone. Even the ones that were doped up for most of their lives like the DDR wrestlers.

Lastly, what causes these features to develop and is there anything that can hinder the development of these features in men? Or to the contrary cause these features to manifest in women?

You can have a lot of frontal bossing and jaw squaring from acromegaly, which is caused by excess growth hormone
