"Web27 Apr 2024 · Background. Luteinizing Hormone (LH) is a glycoprotein secreted by the anterior pituitary. It is composed of two dissimilar subunits. The alpha chain is identical to that of FSH, and very similar to TSH and HCG. The beta chain differs considerably from FSH and TSH, but again is similar to HCG. LH and FSH are members of the gonadotropin family. " - Secretion site of lh
