Neurochemical Regulation of the LHRH Pulse Generatorulation. Their basic features are particularly clearly revealed in gonadectomized individuals (Fig. 1). Changes in LH pulse amplitudes and frequencies during the estrous cycle of the rat have been described (Fox and Smith 1985). In ovariectomized or postmenopausal women the pulse frequency is approx

The presence of at least three distinct types of opiate receptors named μ (my), δ (delta) and κ (kappa) is generally accepted and li

Concentrations of β-endorphin in ovarian follicular fluid were reported to be significantly higher than in peripheral blood, suggesting a local ovarian secretion (Petraglia et al. 1985; Aleem et al. 1987). Recently, a periovulatory increase

Opioidergic Control of the Pituitary-Adrenal Axiscontrol of pituitary hormone secretion. In man, opiates have been shown to inhibit the pituitary-adrenal axis (Grossmann 1983). Thus, β-endorphin suppresses basal ACTH and Cortisol secretion (Taylor et al. 1983). Similarly, the δ-opiate receptor agonist morphine sulfate reduces baseline Cortisol con
