Himmler, inspired by bureaucrats of the Race and Settlement Main Office, hoped to reverse a decline in the "Aryan" birthrate which he attributed to homosexuality among men and abortions among healthy Aryan women,[26] which were not allowed under the 1935 law, but nevertheless practiced.

After the law was challenged in three appeals courts, the U.S. Supreme Court held that it was constitutional because, unlike the earlier Nebraska state law, it was not vague or overly broad.

2007 – The Parliament of Portugal voted to legalize abortion during the first ten weeks of pregnancy. This followed a referendum that, while revealing that a majority of Portuguese voters favored legalization of early-stage abortions, failed due to low voter turnout.[34] The second referendum passed, however, and President Cavaco Silva signed the measure into effect in April, 2007.[35][36]

It is unclear if either of these qualifications was enforced.

Abortion, in other words, could be allowed if it was in the interest of racial hygiene… the Nazis did allow (and in some cases even required) abortions for women deemed racially inferior… On November 10, 1938, a Luneberg court declared abortion legal for Jews.
