Sterilization of Native American women

In the 1960s and 1970s, the Indian Health Service (IHS) and collaborating physicians sustained a practice of performing sterilizations on Native American women, in many cases without the free and informed consent of their patients. Tactics for sterilization included healthcare providers neglecting to tell women they were going to be sterilized and forms of coercion such as threatening to take away welfare or healthcare.
