title: Neurogenic galactorrhea-amenorrhea.
abstract: Neuroendocrine function in two women with galactorrhea-amenorrhea arising from abnormalities in the PRL reflex arc was compared to that of normal women. Basal gonadotropins were lower than normal, and one patient lacked episodic secretion of LH; however, the serum gonadotropin rise after iv LRH was in the normal range in both patients. Mean basal PRL levels were slightly elevated in one patient and were normal in the other, and the PRL levels after TRH, chlorpromazine, and levodopa testing were similar to those seen in normal women. Breast stimulation did not increase PRL levels in either patient. PRL levels fell with bromergocryptine therapy, galactorrhea ceased, and normal menses resumed. These studies indicate that chronic afferent impulses originating in the PRL reflex arc can result in galactorrhea and amenorrhea and that bromergocryptine therapy in such patients can restore normal menses.
