where was the first birth control pill invented
Birth control In 1909, Richard Richter developed the first intrauterine device made from silkworm gut, which was further developed and marketed in Germany by Ernst Gräfenberg in the late 1920s.[156] In 1951, a chemist, named Carl Djerassi from Mexico City made the hormones in progesterone pills using Mexican yams.[157] Djerassi had chemically created the pill but was not equipped to distribute it to patients. Meanwhile, Gregory Pincus and John Rock with help from the Planned Parenthood Federation of America developed the first birth control pills in the 1950s, such as mestranol/noretynodrel, which became publicly available in the 1960s through the Food and Drug Administration under the name Enovid.[146][158] Medical abortion became an alternative to surgical abortion with the availability of prostaglandin analogs in the 1970s and mifepristone in the 1980s.[159]
Birth control in the United States Birth control advocacy organizations around the world also began to collaborate. In 1946, Sanger helped found the International Committee on Planned Parenthood, which evolved into the International Planned Parenthood Federation and soon became the world's largest non-governmental international family planning organization.[26] In 1952, John D. Rockefeller III founded the influential Population Council.[27] Fear of global overpopulation became a major issue in the 1960s, generating concerns about pollution, food shortages, and quality of life, leading to well-funded birth control campaigns around the world.[28] The 1994 International Conference on Population and Development and the 1995 Fourth World Conference on Women addressed birth control and influenced human rights declarations which asserted women's rights to control their own bodies.[29]
