What does estrogen do for women?
but i never got to know specifically how it would affect women.
does it make your voice more lofty pitched/make less hairs on the face/etc, or what?
Answers: Estrogen is what make women... well women. Its not so much the lack of facial tresses and high pitched void as it is breasts and fickle emotion.
Easiest way to see what it does is when men take it (or men who pinch steriods and mess up their estrogen/testosterone balance). They tend to grow femanine-like breast and start to get more emotional. Testosterone is mostly coupled to muscle growth, facial hair, and deeper voice.
