Mary Alice was 14 and Minnie was 12 when they became victims of the abusive practice of sterilizing poor, black women in the South. Their mother, who had very little education and was illiterate, signed an "X" on a piece of paper, expecting her daughters, who were both mentally disabled, would be given birth control shots. Instead, the young women were surgically sterilized and robbed of their right to ever bear children of their own.The Center filed a lawsuit on behalf of the Relf sisters and exposed the wide-spread sterilization abuse funded by the federal government and practiced for decades. The district court found an estimated 100,000 to 150,000 poor people were sterilized annually under federally-funded programs. Countless others were forced to agree to be sterilized when doctors threatened to terminate their welfare benefits unless they consented to the procedures.
