The Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.
