The signing in
I learned today that during the 1950s, Progestin, a synthetic progesterone, was administered to women who had histories of miscarriages. Progestin, a female hormone, is structured similarly to testosterone, and when activated can bond to those receptors, and cause male genitalia tracts to develop without the Y chromosome. The babies of mothers who took Progestin were born, but unfortunately, in some cases the girls' genital tracts were masculinized. In severe cases, the girls were born with what looked like male genitalia, and raised as boys until puberty, when their estrogen levels increased. Got to be a story in there somewhere!
