A substance secreted every ninety minutes or so by a part of the brain called the hypothalamus. This hormone enables the pituitary to secrete LH and FSH, which stimulate the gonads.
Produced by the Hypothalamus, it enables the production of LH and FSH.
Hormones that stop the release of the gonadotropins, thus interrupting ovarian and testicular function.
A substance secreted by the hypothalamus every ninety minutes or so. This hormone enables the pituitary to secrete LH and FSH, which stimulate the gonads. See also FSH; LH.
A hormone that originates in the hypothalamus in the brain. In both women and men, it is responsible for signaling to the pituitary gland to start producing FSH and LH.
The hormone produced and released by the hypothalamus that controls the pituitary gland’s production and release of gonadotropins.
A hormone produced in the brain that directs the pituitary gland to release follicle stimulating hormone and luteinising hormone. Often abbreviated to GnRH.
A substance released from thehypothalamus in a pulsatile manner approximately every 90 minutes. This hormoneacts on the pituitary gland enabling it to secrete LH and FSH, which stimulatethe gonads.
Hormone secreted by the hypothalamus that prompts the pituitary gland to release follicle stimulating hormone (FSH) and luteinizing hormone (LH) into the bloodstream.
Produced by the hypothalamus, this substance controls the production of LH and FSH by the pituitary gland.
A hormone released intermittently by the pituitary gland every 90 minutes. Enables the pituitary to stimulate FSH and LH production
A hormone that is involved in triggering ovulation. Sold under the name Factrel and Lutrepulse.
A hormone produced by the hypothalamus of the brain to regulate production and release of the gonadotropins follicle stimulating hormone and luteinising hormone. Can be administered to induce ovulation when it is deficient (particularly in amenorrhea due to weight loss or excessive exercise), but it has to be given in small amounts directly into a vein, every 60 to 90 minutes for the two weeks of a normal follicular phase (with an electronic syringe-driver), mimicking its natural pattern of secretion. See also: GnRH-analog
This is the hormone that is used by the hypothalamus to stimulate the secretion of FSH and LH from the pituitary.
The hormone which controls the production and release of gonadotropins. Secreted by the hypothalamus every ninety minutes or so, this hormone enables the pituitary to secrete LH and FSH, which stimulate the gonads.
