Androgens have been shown to enhance follicle-stimulating hormones (FSH) induced aromatase activity in cultured granulosa cells obtained from the ovaries of immature rats, however, aromatizable androgens are more effective than nonaromatizable androgens. The present study was designed to investigate the
Inhibition of estrogen biosynthesis and regression of mammary tumors by aromatase inhibitors.

4-Hydroxy-4-androstene-3,17-dione (4-OHA) and 4-acetoxy-4-androstene-3,17-dione (4-AcA), in addition to being competitive inhibitors of aromatase, cause time-dependent, irreversible, loss of enzyme activity in both human placental and rat ovarian microsomes. In vivo, treatment of rats with 4-OHA also causes loss of ovarian
