Stan asked the Naked Scientists:
   From what I understand it is the pituitary gland which produces the hormones which causes you to grow taller and the hypothalamus which signals the pituitary gland when to produce these hormones though nerves.

Would it not be possible to either stimulate these nerves somehow to make short people grow taller, or determine exactly what chemical composition these hormones consists off, duplicate them, and apply them to the blood stream/in pills for the same effect?

What do you think?

Human growth hormone treatment has existed for half a century ...

An unfortunate side-effect of using human growth hormone is that the brain-wasting prion disease CJD (Creutzfeldt–Jakob disease) could be transferred to patients undergoing pituitary hormone therapy.

This was later reduced by better purification of the extracted hormone.
Even later, this risk was avoided entirely by using hormone grown in bacteria, using genetic engineering techniques.
