  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. Corpus luteum - Wikipedia

    en.wikipedia.org/wiki/Corpus_luteum

    Vaginal ultrasound showing a corpus luteum in a pregnant woman, with a fluid-filled cavity in its center. If the egg is fertilised and implantation occurs, the syncytiotrophoblast (derived from trophoblast) cells of the blastocyst secrete the hormone human chorionic gonadotropin (hCG, or a similar hormone in other species) by day 9 post ...

  4. Theca lutein cyst - Wikipedia

    en.wikipedia.org/wiki/Theca_lutein_cyst

    Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.

  5. Theca of follicle - Wikipedia

    en.wikipedia.org/wiki/Theca_of_follicle

    A depiction of the ovarian cycle in animals. In human adult females, the primordial follicle is composed of a single oocyte surrounded by a layer of closely associated granulosa cells. In early stages of the ovarian cycle, the developing follicle acquires a layer of connective tissue and associated blood vessels. This covering is called the theca.

  6. Hypothalamic–pituitary–gonadal axis - Wikipedia

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

    The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone. In oviparous organisms (e.g. fish, reptiles, amphibians, birds), the HPG axis is commonly referred to as the hypothalamus-pituitary-gonadal-liver axis (HPGL-axis) in females ...

  7. Folliculogenesis - Wikipedia

    en.wikipedia.org/wiki/Folliculogenesis

    Five hormones participate in an intricate process of positive and negative feedback to regulate folliculogenesis. They are: gonadotropin-releasing hormone (GnRH) secreted by the hypothalamus; two gonadotropins: follicle-stimulating hormone (FSH) luteinizing hormone (LH) estrogen; progesterone

  8. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    Graves' disease involves the hyperactivity of the thyroid gland which produces the T3 and T4 hormones. [8] Graves' disease effects range from excess sweating, fatigue, heat intolerance and high blood pressure to swelling of the eyes that causes redness, puffiness and in rare cases reduced or double vision.

  9. Ovulation - Wikipedia

    en.wikipedia.org/wiki/Ovulation

    Ovulation is stimulated by an increase in luteinizing hormone (LH). The ovarian follicles rupture and release the secondary oocyte ovarian cells. [1] After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. If it is not, it will break down in less than a day.
