curious wonderings of the science genius girl

So what IS the link between female hormones and gallstones? I know that they are considerably more likely to occur in women, full stop, and then within the subset of women, more likely to occur for: women post-hysterectomy, TS women who didn't have a uterus to start with, and women who are estrogen-dominant. But why?
