Nearly 150 California female inmates were sterilized over the course of 13 years, many of them saying they were pressured into the surgery, according to The Center for Investigative Reporting.
Gloria Killian is a former inmate who now runs the advocacy group Action Committee for Women in Prison.
Killian didn't have the surgery, however "in the minds of a lot of people who work there, we're just kind of sub-human," she said. "You know, we don't deserve to have children. We don't deserve good medical care."
However, no sterilizations have been performed since 2010, said Joyce Hayhoe with California Correctional Health Care Services.
"We took immediate steps to stop the procedure because under our regulations only medically necessary procedures are to be performed on inmates," Hayhoe said.
