The correct option is A Glycoprotein
Follicle stimulating hormone (FSH) is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FSH regulates the development, growth, pubertal maturation and reproductive processes of the body. FSH is a 35.5kD glycoprotein dimer. Its structure is similar to those of LH, thyroid stimulating hormone (TSH), and human chorionic gonadotropin (hCG).
