hypopituitarism: a generalized endocrine deficiency condition produced by failure, either partial or complete, of the pituitary gland to secrete its proper hormones. Failure after surgery for a pituitary tumor is usually complete. Idiopathic failure may be either complete or partial. In some instances, partial failure may involve chiefly the secretion of pituitary gonadotropins, the hormones that stimulate the ovaries or the testes to produce their own hormones.
