In December 1942, Carl Clauberg came to the death camp Auschwitz and received Block 10 for his medical experimental activities. At Auschwitz Professor Carl Clauberg injected chemical substances into wombs during his experiments. Thousands of Jewish and Gypsy women were subjected to this treatment. They were sterilized by the injections, producing horrible pain, inflamed ovaries, bursting spasms in the stomach, and bleeding. The injections seriously damaged the ovaries of the victims, which were then removed and sent to Berlin.
