They take male hormones because females aren't naturally muscular in comparison to men. Steroids don't play a major role in comparison, but muscle is considered a male feature so we automatically say, she's overly muscular, that's not womanly she looks like a man. But yes male hormones give them defined jaws and a masculine body form, steroids enable them to buid these muscles, the more muscle built the more manly a woman will look. These hormones also clash with female hormones, which can make the women infertile and reduce breast size/growth. Which just adds to the problem.
I don't think they look like men exactly, maybe they're just as muscular as a man but their faces definitely don't look manly. Muscles are more than just a male trait. Who says a women can't have muscles too.
I believe women DO produce small amounts of testosterone in their ovaries, though it's usually drowned out by the oestrogen. Bodybuilding happens to accelerate the testosterone production process, and, thus, makes them seem more masculine than other women.
I have a distinct feeling that I may be talking out of my arse, though, so don't quote me on that.
lol female bodybuilder are hot , well most. your thinking of bodybuilders that take types of HGH wich can't be produced in females and makes them grow muscle easier and a side effect is maybe sum masculin features. **Moral is only the ones that do roids look like that**
