Principle

Human Luteinizing Hormone  is made up of two non-identical, non-covalently associated glycoprotein subunits, denoted alpha and beta. In the female, LH stimulates the final maturation of the follicle, follicular rupture, and ovulation.3 Human LH is secreted by the gonadotropic cells of the anterior lobe of the pituitary gland in response to gonadotropin releasing hormone (GnRH) from the medial basal hypothalamus
