Human growth hormones are hormones that stimulate growth and cell reproduction in the body. They are used to help treat a variety of deficiencies in the body including growth hormone deficiency which causes a person to stop growing at a young age. This deficiency can also cause sexual immaturity if left untreated. This can have varying effects on a person's life and possibly even fatal effects. Without human growth hormones these people would have nowhere to turn to but because there are human growth hormones they can be treated. With human growth hormones they can grow again gaining the height of a normal person and live a normal life and not have to put up with the effects of having such a deficiency.
