Mu Opioid Receptor Regulation of Gonadotropin-Releasing Hormone-Luteinizing Hormone Axis during Short-Term Food Deprivation: Role of Alpha1-Adrenoreceptor Signaling.

OBJECTIVES: Brain bio-energetic stability is required for optimal gonadal steroid positive-feedback activation of the gonadotropin-releasing hormone-I (GnRH-I)-pituitary luteinizing hormone (LH) neuroendocrine axis. Caudal hindbrain metabolic-sensory noradrenergic neurons counter energy deficiency by curtailing the mid-cycle LH surge. C.....
