[Sexual dimorphism in the content of luliberin following deafferentation of the mediobasal hypothalamus].
Luliberin (LH-RH) was assayed radioimmmunologically in the hypothalamic fragments taken from male and female rats, intact or with isolated mediobasal hypothalamus. An increased amount of LH-RH was found in the fragments containing organum vasculosum of the lamina terminals (OVLT) and taken from intact males. LH-RH amount was negligible in isolated parts of hypothalamic fragments containing arquate nucleus of median eminence. OVLT of females was mu;ch richer with LH-RH than that of the males. The females though were characterized by a lower blood lutropin. The inhibitory influences on the secretion of LH-RH seem to be more obvious in intact males than in females.
