| − | '''Human growth hormone''' (HGH) is a [[steroid]] that has been used illegally by some athletes to increase their muscle mass and agility. In of February 2008, [[Congress]] investigated several [[baseball]] players, including [[Roger Clemons]], to see if they ever had HGH in their bodies. | + | '''Human growth hormone''' (hGH; Somatotrophin) is a peptide hormone produced naturally by humans in the anterior [[pituitary galnd]]. The control of hGH release is primarily by the [[stimulate|stimulatory]] effect of [[Growth Hormone Releasing Hormone]] (GHRH) and the [[inhibit|inhibitory]] effect of somatostatin, both of which are secreted by the [[hypothalamus]]. The primary effect of hGH in humans is the promotion of bone and muscle growth. It also causes lipolysis (fat breakdown) and aids the body to utilise glucose for energy. As a result, in its synthetic form - recombinant human growth hormone (rhGH), or somatropin - it is a common drug of abuse amongst athletes. |
