I just saw Black Widow. Yelena and Natasha say they don’t have any ovaries because the Red Room surgically removed them. That means no estrogen. But those women have definitely been through puberty. If you don’t have any estrogen or testosterone, your bones get weak like a child’s bones. That’s no good for being a super assassin. And I don’t think the Black Widow is on testosterone injections. She’s not hairy enough for it. So is she taking estradiol pills?
The Red Room hands out estrogen pills as yet another form of control. If you don’t behave, you don’t get your daily fix. You can tell the non-compliant girls by the lack of secondary sex characteristics. Ol Washboard Wendy over there is a rebel!
Also early onset osteoporosis.
