- Luteinizing hormone
- A hormone released by the pituitary gland in response to luteinizing hormone- releasing hormone. Abbreviated LH, it controls the length and sequence of the female menstrual cycle, including ovulation, preparation the uterus for implantation of a fertilized egg, and ovarian production of both estrogen and progesterone. In males, it stimulates the testes to produce androgen. Also known as interstitial-cell-stimulating hormone (ICSH).
* * *luteinizing hormone n a glycoprotein hormone that is secreted by the adenohypophysis and that in the female stimulates ovulation and the development of the corpora lutea and together with follicle-stimulating hormone the secretion of estrogen from developing ovarian follicles and in the male the development of interstitial tissue in the testis and the secretion of testosterone abbr. LH called also interstitial-cell stimulating hormone, lutropin
* * *(LH)a hormone (see gonadotrophin), synthesized and released by the anterior pituitary gland, that stimulates ovulation, corpus luteum formation, progesterone synthesis by the ovary (see also menstrual cycle), and androgen synthesis by the interstitial cells of the testes. Also called: interstitial cell stimulating hormone (ICSH).
* * *(LH) a glycoprotein anterior pituitary hormone that is a gonadotropin (28,000 daltons) and acts with follicle-stimulating hormone to promote ovulation as well as secretion of androgens and progesterone. It instigates and maintains the second (secretory) portion of the mammalian estrus and menstrual cycle. In females it is concerned with corpus luteum formation and in males it stimulates the development and functional activity of testicular Leydig cells. Called also interstitial cellâ€“stimulating h. and lutropin.
