Anterior pituitary disorders

The anterior (front) lobe of the pituitary gland makes up 80 percent of the gland's weight. It releases a variety of hormones that affect growth, physical and sexual development, and other endocrine glands. Oversecretion or undersecretion of certain hormones by the anterior lobe of the pituitary gland will cause other endocrine glands to over- or underproduce certain hormones, as well.
