The effects of supraphysiological levels of testosterone on neural networks upstream of gonadotropin-releasing hormone neurons
Objective(s): Several pathological conditions are associated with hyper-production of testosterone; however, its impacts are not well understood. Hence, we evaluated the effects of supraphysiological levels of testosterone on gonadotropin-releasing hormone (GnRH) system in the hypothalamus of male rats. Also, we assessed the expression of two excitatory (kisspeptin and...
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...
متن کاملImmunization of pigs against chicken gonadotropin-releasing hormone-II and lamprey gonadotropin-releasing hormone-III: effects on gonadotropin secretion and testicular function.
The objective of this experiment was to evaluate the effects of active immunization against 2 GnRH isoforms on gonadotropin secretion and testicular function in pigs. Synthetic chicken (c) GnRH-II and lamprey (l) GnRH-III peptides, with the common pGlu-His-Trp-Ser sequence at the N-terminal omitted, were conjugated to BSA. Forty-eight male piglets were randomly assigned to 1 of 4 treatments. Pi...
متن کاملTREATMENT OF PRECOCIOUS PUBERTY BY A LONG-ACTING GONADOTROPIN-RELEASING HORMONE ANALOGUE IN CHILDREN
The GnRH analogue has been shown to be effective in the treatment of precocious puberty when given as a daily subcutaneous injection. We studied the effectiveness of a long-acting GnRH analogue, Triptoreline, for the treatment of central precocity, by suppressing gonadotropin and estradiol secretion in three children with true precocious puberty. One month after single dose intramuscular i...
متن کاملAntibodies Against Gonadotropin-Releasing Hormone in Patients with Posterior Laryngitis
Patients with functional gastrointestinal disorders express antibodies against gonadotropin-releasing hormone (GnRH) in serum. One common cause of posterior laryngitis (PL) is extra-esophageal reflux, but a functional etiology has also been suggested. The aim of this study was to scrutinize patients with PL with regard to the presence of GnRH antibodies and to examine the association between an...
