Follicle-stimulating hormone (FSH) is a glycoprotein hormone found in humans and other animals. It is synthesized and secreted by gonadotropes of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) act synergistically in reproduction.
Follicle-stimulating hormone (FSH). FSH is a protein made by the brain that stimulates ovulation. If your ovaries are beyond menopause, they no longer respond to FSH, and your brain reacts by sending out even more of these hormones. If your periods have stopped for some time, a persistently high level of FSH (over 40 milli-international units per milliliter, or mIU/mL) indicates that menopause may be permanent.
