Structural and functional regression of polycystic ovaries by danazol.
The effects of danazol on ovarian steroidogenesis and follicular size was studied in androgen-sterilized rats bearing polycystic ovaries. Daily treatment with 4 or 20 mg of the drug caused a reduction in ovarian weight and regression of cystic follicles. Serum levels of luteinizing hormone (LH), testosterone, and estrogen were significantly decreased. The persistent estrus smears were changed to diestrus, indicating inhibition of estrogenic activity.
