The suppressive effects of Danazol, an isoxazol derivative of the synthetic steroid 17 α-ethinyltestosterone, on endometrial DNA synthesis were investigated in rats by immunohistochemistry with bromodeoxyuridine (BrdU) and DNA-synthesizing enzyme assays. Rats treated with Danazol for 14 days at 17-19 weeks of age showed a decrease of plasma gonadotropins associated with ovarian hypofunction, persistent diestrus, and a smaller number of corpora lutea in ovary, resulting in no BrdU-immunoreactive (S-phase) cells in endometrial epithelium and lower activity of thymidine kinase in the uterus compared with control.
