In organizing their eugenics program the Nazis were inspired by the United States' programs of
forced sterilization, especially on the eugenics laws that had been enacted in
California.

The
Law for the Prevention of Hereditarily Diseased Offspring, enacted on July 14, 1933, allowed the compulsory sterilisation of any citizen who according to the opinion of a "Genetic Health Court" suffered from a list of alleged genetic disorders and required
physicians to register every case of hereditary illness known to them, except in women over 45 years of age.
[22]Physicians could be fined for failing to comply.
In 1934, the first year of the Law's operation, nearly 4,000 persons appealed against the decisions of sterilization authorities. A total of 3,559 of the appeals failed. By the end of the Nazi regime, over 200
Hereditary Health Courts (
Erbgesundheitsgerichte) were created, and under their rulings over 400,000 persons were sterilized against their will.
