Criminals, particularly sex offenders, in the USA and other countries have been sterilized as part of their punishment. In India the poor and poorly educated have been given hysterectomies or vasectomies, without knowing what they were, in order to lower birth rates. In none of these cases did the individual concerned have an informed right to say no.
Swedish social democratic governments sterilized 62,000 people, overwhelmingly women, between 1935 and 1976, purportedly to rid society of inferior racial types. Doctors and school authorities selected adults and children and pressured them to consent to sterilization. Many of the 60,000 women candidates were misdiagnosed as being mentally ill.
