Germany: Sterilization experiments begin on women prisoners at Auschwitz-Birkenau.
Women at Auschwitz-Birkenau concentration camp, 1942
The Nazis conducted a series of medical experiments on large numbers of prisoners, mainly Jews (including Jewish children), from across Europe in its concentration camps.
Prisoners were forced to participate; they did not willingly volunteer and there was never informed consent. Typically, the experiments resulted in death, disfigurement or permanent disability, and as such are considered as examples of medical torture.
The various hazardous experiments were designed to help German military personnel in combat situations and to develop new weapons, aid in the recovery of military personnel that had been injured and to advance the racial ideology backed by the Third Reich.
They conducted experiments on bone, muscle and nerve transplantation, head injury, freezing, malaria, mustard gas, sulfonamide, sea water, and even experiments on homosexual prisoners in attempts to cure homosexuality.
Sterilization experiments were designed to develop a method suitable for sterilizing millions of people with a minimum of time and effort. These experiments were conducted by means of X-ray, surgery and various drugs. Thousands of victims were sterilized.
Intravenous injections of solutions speculated to contain iodine and silver nitrate were successful, but had unwanted side effects such as vaginal bleeding, severe abdominal pain and cervical cancer. Therefore, radiation treatment became the favored choice. Specific amounts of exposure to radiation destroyed a person's ability to produce ova or sperm. The radiation was administered through deception. Prisoners were brought into a room and asked to complete forms, which took two to three minutes. In this time, the radiation treatment was administered and, unknown to the prisoners, they were rendered completely sterile. Many suffered severe radiation burns.
After the war, these crimes were tried at what became known as the Doctors' Trial, and revulsion at the abuses perpetrated led to the development of the Nuremberg Code of medical ethics.
