نویسندگان
چکیده
Background: The long protocol has been recognized as the gold standard in controlled ovarian hyperstimulation (COH). However, full dose of gonadotropin-releasing hormone agonist (GnRH-a) under prolonged become increasingly popular China. This study sought to compare pregnancy outcomes among following 3 groups: a group, and 2 types improved groups.

Gonadotropin-releasing hormone agonist-induced pituitary apoplexy
UNLABELLED Pituitary apoplexy represents an uncommon endocrine emergency with potentially life-threatening consequences. Drug-induced pituitary apoplexy is a rare but important consideration when evaluating patients with this presentation. We describe an unusual case of a patient with a known pituitary macroadenoma presenting with acute-onset third nerve palsy and headache secondary to tumour e...
متن کاملAgonist-induced internalization and downregulation of gonadotropin-releasing hormone receptors
Gonadotropin-releasing hormone (GnRH) acts via seven transmembrane receptors to stimulate gonadotropin secretion. Sustained stimulation desensitizes GnRH receptor (GnRHR)-mediated gonadotropin secretion, and this underlies agonist use in hormone-dependent cancers. Since type I mammalian GnRHR do not desensitize, agonist-induced internalization and downregulation may underlie desensitization of ...

Objective The objective of this study is to compare rates of pregnancy and IVF parameters in subjects who were stimulated with follicle stimulating hormone (FSH) plus either recombinant human luteinizing hormone (r-LH) or human menopausal gonadotropins (hMG), in long gonadotropin releasing hormone (GnRH) agonist IVF protocols. MaterialsAndMethods This is a cohort study of patients undergoing IV...
متن کاملPulsatile administration of gonadotropin-releasing hormone agonist to gilts actively immunized against gonadotropin-releasing hormone.
Sexually mature gilts (n = 20) were actively immunized against GnRH. Primary and booster immunizations of GnRH conjugated to bovine serum albumin induced production of antibodies in all gilts. Nineteen of the gilts became acyclic with suppressed concentrations of gonadotropins and estradiol. Intravenous challenges with 100 micrograms GnRH and 5 micrograms D-(Ala6, des-Gly-NH2(10)) ethylamide Gn...
