  2. Luteinizing hormone - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone

    Luteinizing hormone (LH, also known as luteinising hormone, [1] lutropin and sometimes lutrophin [2]) is a hormone produced by gonadotropic cells in the anterior pituitary gland. The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. [ 3 ]

  3. Lateral hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Lateral_hypothalamus

    The lateral hypothalamus (LH), also called the lateral hypothalamic area (LHA), [1] contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; [2] this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature ...

  4. Luteinizing hormone beta polypeptide - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone_beta...

    The luteinizing hormone beta subunit is encoded by a single gene in all mammals. In primates, this gene is located within a cluster that arose through gene duplication, and also includes multiple redundant genes encoding the beta subunit of chorionic gonadotropin as well as several nonfunctional pseudogenes .

  5. Gonadotropin - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin

    Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...

  6. Hypothalamic–pituitary–gonadal axis - Wikipedia

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

    One of the most important functions of the HPG axis is to regulate reproduction by controlling the uterine and ovarian cycles. [18] In females, the positive feedback loop between estrogen and luteinizing hormone help to prepare the follicle in the ovary and the uterus for ovulation and implantation. When the egg is released, the empty follicle ...

  7. Anterior pituitary - Wikipedia

    en.wikipedia.org/wiki/Anterior_pituitary

    The anterior pituitary (also called the adenohypophysis or pars anterior) is a major organ of the endocrine system.The anterior pituitary is the glandular, anterior lobe that together with the (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.

  8. Luteinizing hormone/choriogonadotropin receptor - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone/chorio...

    Luteinizing hormone up-regulates cholesterol side chain cleaving enzyme in sensitive tissues, the first step of all human steroidogenesis. The LHCG receptor's main function is the regulation of steroidogenesis .

  9. Follicle-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating_hormone

    Its structure is similar to those of luteinizing hormone (LH), thyroid-stimulating hormone (TSH), and human chorionic gonadotropin (hCG). The alpha subunits of the glycoproteins LH, FSH, TSH, and hCG are identical and consist of 96 amino acids, while the beta subunits vary. [4] [5] Both subunits are required for biological activity.
