Clinical information
|
Follicle-stimulating hormone (FSH) is a member of the pituitary glycoprotein hormone family which also includes luteinizing hormone (LH) and thyroid-stimulating hormone (TSH).1 Members of the pituitary glycoprotein hormone family consist of a shared alpha subunit and a beta subunit encoded by a separate gene.1-3 The FSHB gene encodes the beta subunit of follicle stimulating hormone.1-3 FSH enables ovarian folliculogenesis and is essential for Sertoli cell proliferation and spermatogenesis.
