Differential regulation of FSH and inhibin gene expression and synthesis by testosterone in immature and mature male rats

FSH in therapy: physiological basis, new preparations and clinical use

Follicle stimulating hormone (FSH) is a glycoprotein hormone secreted by the pituitary gland that, together with luteinizing hormone (LH), controls development, maturation and function of the gonad. Like the related hormones, LH, thyroid stimulating hormone (TSH) and human chorionic gonadotropin (hCG), FSH consists of two polypeptide chains, α and β, bearing carbohydrate moietiesN-linked to asparagine (Asn) residues. The α subunit is common to all members of the glycoprotein hormone family, whereas the β subunit, although structurally very similar, differs in each hormone and confers specificity of action.
