Treatment of vaginal endometriosis with danazol.

Six infertile patients with vaginal endometriosis were treated with danazol at 600 mg daily for 6 months. Three patients had previously undergone surgery for pelvic endometriosis. After 4 months of danazol treatment there was a clear reduction in the size and number of the lesions in all the patients. At the end of the treatment 4 patients still had small lesions, which showed histological evidence of regressive changes. Four women became pregnant within 6 months of the termination of therapy.
