Regulation of pituitary gonadotropin-releasing hormone receptors by pulsatile gonadotropin-releasing hormone injections in male rats. Modulation by testosterone.
The pattern of the gonadotropin-releasing hormone (GnRH) stimulus is critically important in the regulation of pituitary gonadotropin secretion and continuous infusions down-regulate secretion while intermittent pulses maintain luteinizing hormone (LH) and follicle-stimulating hormone (FSH) responsiveness. We examined the effects of pulsatile GnRH administration on pituitary GnRH receptors (GnR...
متن کاملLong-term, low-dose lead exposure alters the gonadotropin-releasing hormone system in the male rat.
Lead is a male reproductive toxicant. Data suggest that rats dosed with relatively high levels of lead acetate for short periods of time induced changes in the hypothalamic gonadotropin-releasing hormone (GnRH) at the molecular level, but these changes were attenuated with increased concentration of exposure. The current study evaluated whether exposure to low levels of lead acetate over longer...
متن کاملThe 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 کاملRapid suppression of plasma testosterone levels and tumor growth in the dunning rat model treated with degarelix, a new gonadotropin-releasing hormone antagonist.
Degarelix (FE 200486) is a member of a new class of water-soluble (>50 mg/ml) gonadotropin-releasing hormone (GnRH) antagonists in clinical development for prostate cancer. Upon subcutaneous administration, degarelix forms a gel that results in a sustained release of the compound into the circulation, immediately blocking GnRH receptors in the pituitary and inducing a fast and sustained suppres...
متن کاملEvaluation of Electromagnetic Field Effect on Oxidative Stress Level, Testosterone Hormone and Sexual Behavior in Male Rat Treated with Omega 3
Abstract Background and Objective: Omega-3s are considered essential fatty acids that cannot be synthesized by human body and should be obtained from foodstuff. This study aimed at evaluating the beneficial effect of Omega-3s ,exposed in Electromagnetic Field (EMF), on sexual behavior ,Serum total testosterone level, malondialdehyde (MDA) level and total antioxidant capacity(TAC) in male...
