[Melatonin and gonadoliberin (LH-RH) cells in rat hypothalamus].
Immature female rats were induced to ovulate by an injection of pregnant mare serum: melatonin, intraperitonealy injected, induce an increase of LH-RH immunoreactive neurons in the hypothalamus. These neurons are localized in septo preoptic, infundibular and premammillary areas.
