yes, hormone therapy will change your bone structure, but it's most effective if you take hormones when you're very young. if you wait until you're an adult like i did, it takes years to see a result.

but, i've been on them for years...

it's just the specific places they measured around the hips. this is one of the very few examples of statistically meaningful sexual dimorphism in humans. if they tested my arms, it would be less of a difference. so, i wonder if i can even ask for that, too.
