lu·te·in·iz·ing hormone

n. Abbr. LH
A hormone produced by the anterior lobe of the pituitary gland that stimulates ovulation and the development of the corpus luteum in the female and the production of testosterone by the interstitial cells of the testis in the male.

luteinizing hormone

(Biochemistry) a gonadotrophic hormone secreted by the anterior lobe of the pituitary gland. In female vertebrates it stimulates ovulation, and in mammals it also induces the conversion of the ruptured follicle into the corpus luteum. In male vertebrates it promotes maturation of the interstitial cells of the testes and stimulates androgen secretion. Abbreviation: LH Also called: interstitial cell-stimulating hormone See also follicle-stimulating hormone, prolactin
[C19: from Latin lūteum egg yolk, from lūteus yellow]


luteinizing hormone: a pituitary hormone that acts in the ovary to stimulate ripening of the follicle and formation of the corpus luteum.

luteinizing hormone

(LH) A hormone that in females helps to make ova mature and triggers ovulation, and in males makes testes produce testosterone. LH comes from the pituitary gland and acts with FSH. See folliclestimulating hormone.
