  2. Hypothalamic–pituitary–gonadal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    Fluctuations in this axis cause changes in the hormones produced by each gland and have various local and systemic effects on the body. The axis controls development, reproduction, and aging in animals. Gonadotropin-releasing hormone (GnRH) is secreted from the hypothalamus by GnRH-expressing neurons.

  3. 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 .

  4. GnRH neuron - Wikipedia

    en.wikipedia.org/wiki/GnRH_Neuron

    The strongest activator of GnRH neurons is a hormone called kisspeptin. [16] GnRH neurons also integrate information from the body through hormones like neuropeptide Y [17] and adiponectin. [18] These hormones provide the GnRH neurons with information about the body's status to help determine whether reproduction should be prioritized or ...

  5. Releasing and inhibiting hormones - Wikipedia

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

    The hypothalamus uses RFRP-3 in mammals or GnIH in avian species to inhibit GnRH. The hypothalamus uses follistatin to tell the pituitary to inhibit follicle-stimulating hormone; it also has many other systemic effects. Myocytes use myostatin to tell each other to inhibit myogenesis. Melanocyte-inhibiting factor (melanostatin) inhibits release ...

  6. Gonadotropic cell - Wikipedia

    en.wikipedia.org/wiki/Gonadotropic_cell

    GnRH is a hormone released by the hypothalamus, and it is responsible for signaling gonadotrophs to release gonadotropins FSH and LH. GnRH binds to gonadotropin-releasing hormone receptors (GnRHR), which is a G-protein coupled receptor, and signals the oscillation of calcium that hyperpolarizes gonadotropic cell membranes. [6]

  7. 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.

  8. List of human hormones - Wikipedia

    en.wikipedia.org/wiki/List_of_human_hormones

    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.

  9. Gonadarche - Wikipedia

    en.wikipedia.org/wiki/Gonadarche

    Gonadarche marks the beginning of puberty and it is the process in which gonads, or the primary reproductive organs, mature, following stimulation of gonadotropin hormone-releasing hormone (GnRH) release in the hypothalamus. [6] The release of GnRH triggers a release of hormones that activate the maturation of the ovary and testis. [3] This ...
