Follicle-stimulating hormone (FSH) is a hormone found in humans and other animals. It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FSH is a glycoprotein. Each monomeric unit is a protein molecule with a sugar attached to it; two of these make the full, functional protein. The protein dimer contains 2 polypeptide units (1)., labeled alpha and beta subunits. The alpha subunits contain 92 amino acids. The beta subunits vary. FSH has a beta subunit of 118 amino acids (FSHβ), which confers its specific biologic action and is responsible for interaction with the FSH-receptor. The sugar part of the hormone is composed of fucose, galactose, mannose, galactosamine, glucosamine, and sialic acid, the latter being critical for its biologic half-life. The half-life of FSH is 3-4 hours. FSH regulates the development, growth, pubertal maturation, and reproductive processes of the human body.
