On 7 June 1965, in Griswold v. Connecticut (1965), the United States Supreme Court decided, in a seven to two decision, that married couples have the right to purchase and use contraceptives without government restriction. The case considered the constitutionality of a Connecticut state statute from 1879 that prohibited the sale or use of any contraceptive device or medication. In 1961, Estelle Griswold, an executive director of the Planned Parenthood League of Connecticut, hereafter PPLC, and physician Charles Lee Buxton were convicted for selling contraceptives at a pregnancy clinic they opened in New Haven, Connecticut, in violation of state law. Griswold and Buxton challenged the constitutionality of the Connecticut law, claiming it violated the Due Process Clause of the Fourteenth Amendment of the US Constitution, which states that the state government cannot infringe upon rights of citizens without a fair process, such as a trial. Griswold v. Connecticut helped establish an inferred right to privacy within the amendments of the US constitution, granting the right of married couples to access contraceptives and setting the foundation for future cases involving contraception, abortion, anti-sodomy laws, and marriage.

On 22 March 1972, in Eisenstadt v. Baird, hereafter Eisenstadt, the United States Supreme Court determined, in a six to one decision, that unmarried individuals have the same right to access contraceptives as married couples. Eisenstadt involved William Baird, a reproductive rights advocate who intentionally broke Massachusetts law in 1967 by giving a speech about birth control at Boston University in Boston, Massachusetts, and giving an unmarried, nineteen-year-old woman contraceptives. Baird argued that laws against unmarried people accessing contraceptives unfairly discriminated against unmarried people and denied them reproductive autonomy. Massachusetts law, however, stated that contraceptives could only be distributed by medical professions to married people. The case followed a similar legal challenge from 1965, Griswold v. Connecticut, hereafter Griswold, which found that married individuals have the right to access contraceptives based on a constitutional right to privacy in the US. Eisenstadt reinforced the constitutional right to privacy and equalized the accessibility to contraceptives for married and single individuals.
