In response to the criticism of unethical human experimentation, the Reich government issued "Guidelines for New Therapy and Human Experimentation" in Weimar Republic, Germany. The guidelines were based on beneficence and non-maleficence, but also stressed legal doctrine of informed consent. The guidelines clearly distinguished the difference between therapeutic and non-therapeutic research. For therapeutic purposes, the guidelines allowed administration without consent only in dire situations, but for non-therapeutic purposes any administration without consent was strictly forbidden. However, the guidelines from Weimar were negated by Adolf Hitler. By 1942, the Nazi party included more than 38,000 German physicians, who helped carry out medical programs such as the Sterilization Law.
