In 1942, the United States Supreme Court Case of Skinner v. Oklahoma ruled that states could not legally sterilize those inmates of prisons deemed habitual criminals. Skinner v. Oklahoma was about the case of Jack Skinner, an inmate of the Oklahoma State Penitentiary in McAlester, Oklahoma, who was subject to sterilization under the Oklahoma Habitual Criminal Sterilization Act of 1935. The case, decided on 1 June 1942, determined that state laws were unconstitutional if those laws enabled states to forcibly sterilize inmates deemed to be habitual criminals. Such laws violated the Equal Protection Clause of the Fourteenth Amendment to the US Constitution. The Skinner v. Oklahoma decision also reflected tensions in US eugenic policies when juxtaposed against similar policies of the Nazi regime in Europe, especially with regard to sterilization measures.

In 1996, the US Congress mandated that the US Environmental Protection Agency (EPA) create and regulate the Endocrine Disruptor Screening Program. The program tests industrial and agricultural chemicals for hormonal impacts in humans and in wildlife that may disrupt organisms' endocrine systems. The endocrine system regulates the release of small amounts of chemical substances called hormones to keep the body functioning normally. Some chemicals can impede the endocrine system's function by mimicking or blocking hormone reception, which can disrupt processes of development and reproduction and harm organisms. As of 2017, the Endocrine Disruptor Screening Program is the largest US program to identify and regulate chemicals that affect the normal production of sex hormones like estrogen and androgen, which can have long-term effects on development and reproduction.
