Heinrich Himmler inspecting the camp brothel in Mauthausen/Gusen In combination with the German military brothels in World War II, it is estimated that at least 34,140 female inmates were forced into sexual slavery during the Third Reich. The women forced into these brothels came mainly from the Ravensbrück concentration camp, except for Auschwitz, which employed its own prisoners. In the end, the camp brothels did not produce any noticeable increase in the prisoners' work productivity levels, but instead, created a market for coupons among the camp VIPs. In World War II, Nazi Germany established brothels in the concentration camps ( Lagerbordell) to create an incentive for prisoners to collaborate, although these institutions were used mostly by Kapos, 'prisoner functionaries' and the criminal element, because regular inmates, penniless and emaciated, were usually too debilitated and wary of exposure to Schutzstaffel (SS) schemes.
