Cytosolic and nuclear progesterone receptor levels (RPC RPN) were measured in normal and in pathological human endometria after single-dose progesterone injection 1-3 h before tissue collection (test subjects) and the results compared to those obtained in controls (no progesterone treatment). In test cases of late proliferative or midcycle normal endometria and in estrogen-primed normal postmenopausal endometria, RPN levels were higher and RPC levels were lower compared with those obtained in control samples. In test cases of postmenopausal pathological endometria, histologically normal endometria of women with postmenopausal bleeding and in one case of endometrial polyp, RPN levels were also higher and RPC levels lower than those in the respective controls, but the change of distribution of the RP (cytosol/nuclear extract) was significantly lower than in normal endometrium.
