Testosterone Replacement

Whenever I see lesbians on tv or in public, it seems that they always
have more masculine facial features. A lot of them have more wrinkles
on their faces, rougher looking faces, and they look more masculine in
general. Has there been research to show that this is actually true,
and if so, what would the reason be? Is it a low amount of estrogen
compared to straight women? Or just an inordinate amount of testosterone?
