LH
Luteinizing hormone or lutropin (LH) is a glycoprotein secreted by the gonadotropic cells of the anterior pituitary. LH stimulates testosterone secretion by the Leydig cells of the testes and ovulation and development of the corpus luteum. The assay is indicated for the investigation of abnormalities of the hypotalamo-hypophyso-gonadal axis, e.g. at pubertal abnormalities, infertility and menstrual disorders.
