 The success rate of bromocriptine in amenorrhoea.
 If hyperprolactinaemia is the cause of amenorrhoea, the chances of restoring normal gonadal function with bromocriptine are very good. After one month of treatment, one woman in four will return to normal menstrual cycling: within two months, this number will increase to six out of ten, and after ten months, eight out of ten women will be menstruating normally. (Most of the remaining twenty per cent have had pituitary surgery and irradiation therapy and were gonadotrophin deficient).
