There is increasing evidence that leptin is a physiological link between obesity and infertility. Although leptin receptors have been demonstrated in human ovaries, there is no information regarding the effects of leptin on cells from developing ovarian follicles. To test the direct effects of leptin on human ovarian cells, granulosa cells (GC) and theca(More)
The present studies investigated the role of glucocorticoid receptors (GR) in the inhibitory effects of acute and chronic immobilization stress on pituitary luteinizing hormone (LH) release. Systemic administration of the GR antagonist, RU486, significantly attenuated the acute decline in circulating LH observed in intact male rats immobilized by encasement(More)
While it has been shown that intracerebral administration of exogenous glucocorticoids diminishes pituitary luteinizing hormone (LH) release, it is not known if these hormones act directly on gonadotropin-releasing hormone (GnRH)-synthesizing neurons, or if their central inhibitory effects are mediated by specific neural substrates. In the present study, we(More)
