How Is Recombinant HGH Manufactured?

Prior to the 1980s, the only source of pharmaceutical growth hormone was extraction from the pituitary glands of human cadavers, a process that yielded very small quantities and required pooling material from many donors. That extraction method was discontinued after cases linked it to transmission of Creutzfeldt-Jakob disease, a rare and serious neurological condition, prompting an urgent search for an alternative source.

Recombinant DNA technology provided that alternative: scientists inserted the gene encoding human growth hormone into a host organism's genetic material, engineering it to produce the hormone as it grew. The resulting protein is purified and processed into pharmaceutical-grade somatropin. This approach eliminated the disease-transmission risk of cadaveric extraction and allowed production at a scale the earlier method could never achieve, enabling broader — but still prescription-only — clinical use from the 1980s onward.
