From about March 1941 to January 1945, Nazi Dr. Carl Clauberg did medical experiments on many women at Auschwitz. He wanted to find a way to sterilize millions of people as easily and quickly as possible. He tried using X-rays, surgery, and medications to sterilize women prisoners. The Nazis' plan was to get rid of everyone who was not "Aryan." As part of this plan, the Nazis sterilized many people so they could not have children who were not "Aryan."
