Naturally, the problem was that it didn’t work. There wasn’t any testosterone in the testicular extracts—patients would be injected with a water-based extract, and testosterone does not go into solution in water. And the smidgens of organs that were transplanted would die almost immediately, with the scar tissue being mistaken for a healthy graft. And even if they didn’t die, they still wouldn’t work—if aging testes are secreting less testosterone, it is not because the testes are failing, but because another organ (stay tuned) is no longer telling them to do so.
