Would a 17 alpha hydroxylase XY male have uterus/tubes? I didn't think so as MIF on the Y chromosome would knock it out.... Kaplan Qbank says otherwise. PS in terms of distinguishing 17 alpha hydrox. def from Testicular Feminization syndrome in an XY, -the main difference symptomologically would be breasts at puberty (in AR because testosterone aromatize to estrogen)? Anyone got anything else?
