Infertility caused by hyperprolactinemic amenorrhea may be complicated by 
pituitary adenoma. In a group of 36 women with 
amenorrhoea-hyperprolactinemia-syndrome were 15 infertility-patients. 10 of them 
had prolactin levels above 100 ng/ml. In 6 patients a prolactinoma was removed 
microsurgically. In every case further treatment was necessary to get normal 
cycles. 8 of these 10 infertility-patients became pregnant.
