Compulsory sterilization, also known as forced or coerced sterilization, is a government-mandated program to involuntarily sterilize a specific group of people. Sterilization removes a person's capacity to reproduce, and is usually done through surgical procedures. Several countries implemented sterilization programs in the early 20th century. Although such programs have been made illegal in most countries of the world, instances of forced or coerced sterilizations persist. Rationalizations for compulsory sterilization have included eugenics, population control, gender discrimination, limiting the spread of HIV, "gender-normalizing" surgeries for intersex people, and ethnic genocide. In some countries, transgender individuals are required to undergo sterilization before gaining legal recognition of their gender, a practice that the United Nations Special Rapporteur on torture and other cruel, inhuman or degrading treatment or punishment has described as a violation of the Yogyakarta Principles. Affected populations Governmental family planning programs emerged in the late 19th century and have continued to progress through the 21st century. During this time, feminists began advocating for reproductive choice, but eugenicists and hygienists were advocating for low income and disabled peoples to be sterilized or have their fertility tightly regulated in order to "clean" or "perfect" nations. The second half of the 20th century saw national governments uptake of neo-Malthusian ideology that directly linked population growth to increased (and uncontrollable) poverty, which during the embrace of capitalism, meant that countries were unable to economically develop due to this poverty. Much of these governmental population control programs were focused on using sterilization as the main avenue to reduce high birth rates, even though public acknowledgement that sterilization made an impact on the population levels of the developing world is still widely lacking. Early population programs of the 20th century were marked as part of the eugenics movement, with Nazi Germany's programs providing the most well-known examples of sterilization of disabled people, paired with encouraging ethnic Germans who fit the "Aryan race" phenotype to rapidly reproduce. In the 1970s, population control programs focused on the "third world" to help curtail over population of poverty areas that were beginning to "develop" (Duden 1992). As of 2013, 24 countries in Europe required sterilization for legal gender recognition and 16 countries did not provide for any possibility to change legal gender at all, which meant that transgender people could have challenges applying for jobs, opening bank accounts, boarding planes, or may not be able to do these things at all.
