Zinc supplementation does not inhibit basal and metoclopramide-stimulated prolactinemia secretion in healthy men
(Urban & Fischer Verlag, 2002-01-01)
Dopamine (DA) and zinc (Zn++) share common mechanisms in their inhibition of prolactin (PRL) secretion. Both substances are present in the same brain areas, where Zn++ is released together with DA, suggesting a modulatory ...
