Pulsatile 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 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 کاملEvaluation of different strain mice during in vitro fertilization and embryo development in response to superovulation
Background: Mice are the most commonly used animal in reproductive research and following the urgent need for these type of studies and also due to the increased interest in the ethical principle of animal rights, four various inbred and outbred strains of the laboratory mouse were evaluated to select the more efficient one for reproductive research. Materials and methods: 60 female and 16 mal...
متن کاملRegulation 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...
