The 23 pages that link to Luteinizing hormone, each with the reason it gives.

• Menstrual cycleRelated: A sharp mid-cycle surge precipitates release of the egg.

• TestosteroneRelated: In the testes, it stimulates Leydig cells to produce testosterone.

• PubertyRelated: Its rising secretion helps stimulate gonadal hormone production.

• OvulationRelated: Its midcycle surge initiates the events that release the egg.

• Hypothalamic–pituitary–gonadal axisRelated: It carries pituitary signals to gonads and helps control sex-steroid production.

• Polycystic ovary syndromeRelated: Altered signaling between the brain and ovaries is one proposed part of the syndrome’s hormonal pattern.

• Thyroid-stimulating hormoneRelated: Its structural relationship to TSH helps explain shared hormone-family features, despite different targets.

• HypogonadismRelated: Its blood level helps distinguish gonadal failure from insufficient central stimulation.

• GonadRelated: It stimulates testosterone production in testes and supports ovulation and steroid production in ovaries.

• Gonadotropin-releasing hormoneRelated: GnRH stimulates its release, and its surge triggers ovulation.

• OogenesisRelated: Its surge induces ovulation and resumes meiosis in the human oocyte.

• Ovarian follicleRelated: Its midcycle surge changes the mature follicle from growth to rupture.

• Testosterone replacement therapyRelated: Its level helps distinguish testicular failure from inadequate pituitary stimulation.

• AnovulationRelated: A missing or inadequate surge can leave a mature follicle unruptured.

• Delayed pubertyRelated: Its blood concentration helps distinguish central signaling problems from gonadal dysfunction.

• Luteal phaseRelated: Its surge initiates ovulation, after which luteal hormone production begins.

• Precocious pubertyRelated: Basal or stimulated levels help distinguish central from peripheral causes.

• LevonorgestrelRelated: Levonorgestrel emergency contraception is less effective once the luteinizing-hormone surge has begun.

• ClomifeneRelated: The increased gonadotropin signal can culminate in an LH surge and ovulation.
