Endometrial hyperplasia is a precursor lesion of endometrial carcinoma. Clinical studies of endometrial hyperplasia have shown that levonorgestrel (LNG) is more therapeutically effective than medroxyprogesterone acetate (MPA). The present pharmacological in vitro study was performed to compare progestin effects on
