  2. Gonadotropin-releasing hormone - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin-releasing_hormone

    Gonadotropin-releasing hormone (GnRH) is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is a tropic peptide hormone synthesized and released from GnRH neurons within the hypothalamus .

  3. Gonadotropin-releasing hormone agonist - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin-releasing...

    A gonadotropin-releasing hormone agonist (GnRH agonist) is a type of medication which affects gonadotropins and sex hormones. [1] They are used for a variety of indications including in fertility medicine and to lower sex hormone levels in the treatment of hormone-sensitive cancers such as prostate cancer and breast cancer, certain gynecological disorders like heavy periods and endometriosis ...

    The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.

    The hypothalamus produces and releases gonadotropin-releasing hormone (GnRH). GnRH nudges the pituitary gland to produce luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

  6. Gonadotropin - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin

    Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from the arcuate nucleus and preoptic area of the hypothalamus. The gonads — testes and ovaries — are the primary target organs for LH and FSH. The gonadotropins affect multiple cell types and elicit multiple responses from the target organs.

  7. Releasing and inhibiting hormones - Wikipedia

    en.wikipedia.org/wiki/Releasing_and_inhibiting...

    For example, thyrotropin-releasing hormone (TRH) is released from the hypothalamus in response to low levels of secretion of thyroid-stimulating hormone (TSH) from the pituitary gland. The TSH in turn is under feedback control by the thyroid hormones T4 and T3. When the level of TSH is too high, they feed back on the brain to shut down the ...

  8. Gonadotropin-releasing hormone family - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin-releasing...

    The gonadotropin-releasing hormones (GnRH) (gonadoliberin) [1] are a family of peptides that play a pivotal role in reproduction. The main function of GnRH is to act on the pituitary to stimulate the synthesis and secretion of luteinizing and follicle-stimulating hormones, but GnRH also acts on the brain, retina, sympathetic nervous system, gonads, and placenta in certain species.

  9. Gonadotropin-releasing hormone modulator - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin-releasing...

    A gonadotropin-releasing hormone antagonist (GnRH antagonist) is a GnRH modulator that blocks the GnRH receptor resulting in an immediate drop in gonadotropin (FSH, LH) secretion. GnRH antagonists are primarily used in IVF treatments to block natural ovulation.
