Sweden will not allow the change of gender on legal documents without the person in question going on to hormones, yet leaving it to the individual to pay for any egg or sperm freezing, this is still extremely problematic as: United States During the Progressive Era ( to 1920), the United States was the first country to concertedly undertake compulsory sterilization programs for the purpose of eugenics. Thomas C. Leonard, professor at Princeton University, describes American eugenics and sterilization as ultimately rooted in economic arguments and further as a central element of Progressivism alongside wage controls, restricted immigration, and the introduction of pension programs. The heads of the programs were avid proponents of eugenics and frequently argued for their programs which achieved some success nationwide mainly in the first half of the 20th century. Eugenics had two essential components. First, its advocates accepted as axiomatic that a range of mental and physical handicaps—blindness, deafness, and many forms of mental illness—were largely, if not entirely, hereditary in cause. Second, they assumed that these scientific hypotheses could be used as the basis of social engineering across several policy areas, including family planning, education, and immigration. The most direct policy implications of eugenic thought were that "mental defectives" should not produce children, since they would only replicate these deficiencies, and that such individuals from other countries should be kept out of the polity. The principal targets of the American sterilization programs were intellectually disabled people and the mentally ill, but also targeted under many state laws were the deaf, the blind, people with epilepsy, and the physically deformed. While the claim was that the focus was mainly the mentally ill and disabled, the definition of this during that time was much different from today's. At this time, there were many women that were sent to institutions under the guise of being "feeble-minded" because they were promiscuous or became pregnant while unmarried. A relative minority of sterilizations targeting crime took place in prisons and other penal institutions. In the end, over 65,000 individuals were sterilized in 33 states under state compulsory sterilization programs in the United States, in all likelihood without the perspectives of ethnic minorities. The first state to introduce a compulsory sterilization bill was Michigan, in 1897, but the proposed law failed to pass. Eight years later Pennsylvania's state legislators passed a sterilization bill that was vetoed by the governor. Indiana became
