In the United States, between 1907 and 1978, the proliferation of eugenic state practices routinely targeted institutionalized women with legalized involuntary sterilization. Sterilization laws and policies were a form of reproductive control, which predominantly impacted women from marginalized communities. After the implementation of federal regulations prohibiting involuntary sterilization practices, state agencies continued to engage in coercive sterilization under the guise of “voluntariness.” Using a reproductive justice framework, we introduce a concept of reproductive control embedded within the carceral state. Tracing historical sterilization practices and examining the use of long-acting reversible contraceptives (LARC), we argue that LARC represents a different form of involuntary sterilization. The emergence of LARC as a highly effective, nonagentive, and mediated form of contraception for vulnerable populations demands interrogation. We identify the use of LARC as soft sterilization, which is both related to and distinct from other forms of reproductive control. As such, reproductive autonomy is not possible without the destruction of the carceral state.
