title: Simultaneous pulsatile release of prolactin and luteinizing hormone induced by luteinizing hormone-releasing factor agonist.
abstract: Subcutaneous injection of 50 microgram long acting agonist of LRF (LRF-Ag) resulted in the prompt, simultaneous pulsatile release of both LH and PRL in four hypogonadal women. After repeated daily administration of LRF-Ag. LH release in response to LRF-Ag was markedly attenuated, and LH pulses were abolished. LRF-Ag induced PRL release was also attenuated but remained pulsatile. These findings demonstrate the dissociation of the LRF-Ag-induced contemporaneous release of LH and PRL and suggest a hypothalamic site of action of LRF-Ag on PRL release.
