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.
During this phase, the pituitary gland, located at the base of the brain, releases two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which stimulate the ovary and cause follicular growth. The developing follicle secretes the hormone estrogen, which has several important roles in the body.
