An abnormality of oestrogen feedback in amenorrhoea-galactorrhoea
Abstract
Fourteen patients with amenorrhoea and hyperprolactin-anemia but no evidence of pituitary tumours were each given an intramuscular injection of 1 mg oestradiol benzoate. Thirteen patients failed to release luteinizing hormone in response to the oestrogen. This hypothalamic abnormality may help to explain the menstrual disturbances in subjects with hyperprolactinaemia.
