There were no other physical findings. A laparoscopy revealed the presence of ectopic endometrial tissue on the uterine wall and ovaries. Danazol (a synthetic androgen and inhibitor of gonadotropins), 600 mg/day, was prescribed for up to nine months to inhibit ovulation, suppress the growth of the abnormal endometrial tissue, and achieve appreciable symptomatic relief, with a 30% possibility of conception after withdrawal of the therapy.
