 Although contraceptive information in popular media was curtailed, technical and medical journals and textbooks were not subject to this regulation, and physicians continued to discuss both issues and technologies pertaining to birth control.The early 20th century saw a resurgence of interest in birth control in the United States, due largely to the efforts of Margaret Sanger, Fania Mindell and other social activists.One of the most outspoken advocates for contraception during this time was Emma Goldman, who openly defied the Comstock laws by recommending the womb veil in leaflets she distributed after her lectures.
