Heinrich Himmler on 7 July 1942 ordered experimentation on women at Auschwitz concentration camp, which would later be extended to males. The purpose of the experiments was to find ways to sterilize Jews.

Extermination of Jews was something Himmler and many, including Hitler, fully supported. As head of the Schutzstaffel(SS) as well as the assistant chief of the Gestapo, he controlled all the secret police and paramilitary forces in Germany. This power gave Himmler the power to carry out Hitler’s Final Solution and the reason why he called for a conference about conducting such experiments. Attending the conference were SS General Richard Glueks (hospital chief), SS Major-General Karl Gebhardt, and Professor Karl Clauberg (a leading German gynecologist) and members of the Concentration Camp Protectorate.
It was decided that the experiments on sterilization would be done in a way women would not know what was being done to them. The experiments would reveal the best methods of sterilizing Jewish women and how to sterilize men as well using X-rays. Hitler approved but it was kept top secret. A prior plan to euthanize disabled people, those suffering from incurable diseases, or confined due to mental disorders had resulted in a public outcry they did not want repeated. One of the main reasons for sterilization was to use it in places where concentration camps could not be built. It was expanded to others they deemed inferior (Slavs, Roma, homosexuals etc.) Using medical treatments to hide their true objective of killing Jews would be revealed after the war.
