LH

Synonyms

  • Luteinizing Hormone
  • Luteinising hormone

Clinic significance

A glycoprotein hormone secreted by the anterior pituitary when stimulated by LH-RH produced in the hypothalamus. In females, LH synergizes with FSH to stimulate estrogen production and this test is useful in IVF(assisted conception) protocols for following ovarian stimulation or for diagnosing Stein-Leventhal syndrome. In females the secretion of LH is under the control of ratio of estrogen/progesterone. In males, LH acts on interstitial testicular cells to stimulate testosterone production and this test (in parallel with FSH) (to a FSH assay) is useful in investigations of impaired gonad function.
