Growth Hormone Deficiency in Men

In boyhood, the human growth hormone (GH) controls a young man's height. It is normal for GH levels to decline as a male reaches adulthood, but new research suggests that some males may have too low a level. Low levels of GH are linked to poor muscle tone, increase body fat, low energy levels, and cardiovascular changes. GH insufficiency is associated with pituitary gland problems, brain injury, autoimmune disorders, and nervous system conditions in men.
