The Preovulatory Surge of Gonadotropin Releasing Hormone
1992The regulation of gonadotropin releasing hormone secretion during the preovulatory surge of luteinizing hormone has been a focus of neuroendocrinological investigation for decades. Although it is clear that an increase in estradiol secretion from the developing follicle is an essential ovarian signal for the LH discharge, a fundamental question remains:

Gonadotropin-releasing hormone in practice.
Archives of internal medicine, 1986To the Editor. —Allan R. Glass, MD, made several excellent points in his letter in the March issue of theArchives 1 comparing the merits of pulsatile gonadotropin-releasing hormone (Gn RH) therapy with conventional gonadotropin therapy. We agree that the expense of pulsatile Gn RH therapy has been a disappointment, thus far.

In rhesus monkeys with hypothalamic lesions that abolish gonadotropic hormone release by the pituitary gland, the constant infusion of exogenous gonadotropin-releasing hormone (GnRH) fails to restore sustained gonadotropin secretion.

Gonadotropin-Releasing Hormone And Reproductive Medicine
Journal of Obstetrics and Gynaecology Canada, 2003The hypothalamic gonadotropin-releasing hormone (GnRH) is a key regulator of the reproductive system, mainly through its effects on pituitary luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release. Gonadotropin-releasing hormone analogues are modifications of the natural decapeptide, being either agonists (GnRHa) or antagonists.

Mechanism of Action of Gonadotropin Releasing Hormone
Annual Review of Physiology, 1986GnRH interacts with a plasma membrane receptor to provoke gonadotropin release, as well as regulate numbers of its own receptor and target cell responsiveness. Receptor numbers are altered in different physiological states of the animal. Microaggregation of the GnRH receptor mimics all known actions of the releasing hormone, and therefore is viewed as ...

Neuroimmunomodulation by Gonadotropin Releasing Hormone
Advances in Neuroimmune Biology, 2011Gonadotropin-releasing hormone (GnRH) and GnRH receptor are produced locally by immune cells, suggesting an autocrine or paracrine role for GnRH within the immune system. The lymphocytes (T, B and NK cells), monocytes, macrophages, neutrophils, eosinophils and mast cells are affected directly or indirectly by GnRH. GnRH or GnRH agonists regulate immune

Gonadotropin-Releasing Hormone Agonists for Endometriosis
New England Journal of Medicine, 2008A 36-year-old woman with a presumptive diagnosis of endometriosis presents with long-standing pelvic pain that is not relieved by means of oral contraceptives or medroxyprogesterone. Treatment with a gonadotropin-releasing hormone agonist is recommended.

Gonadotropin Releasing Hormone Treatment
1996Gonadotropin releasing hormone is produced by cells in the medial-basal hypothalamus and delivered to the portal circulation via the GnRH-tuberoin-fundibular tract. The arcuate nucleus is the central site of action, releasing GnRH into the portal circulation in a pulsatile fashion.
