Abstract
Endocrine therapy has produced dramatic results in some situations in obstetrics and gynecology and is beneficial in amenorrhea of unknown origin, in some menopausal patients, and in some cases of endometriosis. It also seems to retard progression of metastasis in patients who have had surgery or radiotherapy in breast cancer. Nevertheless, the physician must guard against using endocrine therapy injudiciously and limit it to only those conditions in which it is of proved benefit.
