In December 1942, Professor Carl Clauberg came to the deathcamp Auschwitz and started his medical experimental activities. He 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.
