The pituitary gland is a small bean-shaped gland that is located beneath the brain at the base of the skull. It is often referred to as the "master gland" - since it controls the secretions of hormones.
These hormones can have a dramatic and broad range of effects on growth and maturation; sexuality and reproduction; and overall metabolism.
Occasionally, pituitary tumors can occur. While these tumors are often benign, they must be monitored so that they do not eventually press on important nerves and brain tissue.
