Illness requiring hormone replacement therapy

In 1985, the USA Food and Drug Administration approved human growth hormone (HGH) for use in the approximately 20,000 children with hormone deficiency, either of unknown cause or from damage to the pituitary gland. With a year's treatment costing $10,000 to $20,000, HGH's two manufacturers together have annual sales of more than $200 million.
