Birth Control Review was a lay magazine established and edited by Margaret Sanger in 1917, three years after her friend, Otto Bobsein, coined the term "birth control" to describe voluntary motherhood or the ability of a woman to space children "in keeping with a family's financial and health resources.". Sanger published the first issue while imprisoned with Ethel Byrne, her sister, and Fannie Mindell for giving contraceptives and instruction to poor women at the Brownsville Clinic in New York. Sanger remained editor-in-chief until 1928, when she turned it over to the American Birth Control League. The last issue was published in January 1940.
