On 30 June 1980, in a five to four decision, the US Supreme Court ruled in the Case Harris v. McRae that the Hyde Amendment of 1976 did not violate the US Constitution. The Hyde Amendment banned the use of federal funding to pay for any abortion services. The US Supreme Court's decision in Harris v. McRae overturned the decision of McRae v. Califano (1980), in which the US District Court for the Eastern District of New York had ruled that the funding restrictions established by the Hyde Amendment violated the US Constitution. After the US Supreme Court's ruling in Harris v. McRae, the Hyde Amendment continued to prohibit federal Medicaid funding for abortion services, limiting the funds available for low-income women seeking abortions.

In the case of Beal v. Doe, tried in 1977, the US Supreme Court ruled that states could constitutionally restrict money from Medicaid from funding elective abortions. After the 1973 case Roe v. Wade, in which the US Supreme Court had ruled women have the rights to terminate pregnancies within the first trimester, the state of Pennsylvania passed legislation that restricted the use of Medicaid funds for abortion procedures. In 1977, several Medicaid eligible women who were unable to receive coverage for a non-therapeutic abortion brought a case against Frank S. Beal, secretary of the Department of Public Welfare of Pennsylvania. The US Supreme Court decision in Beal v. Doe gave states the authority to place Medicaid restrictions on funding for non-therapeutic or elective abortions.

In 1901, the Arizona Territorial Legislature codified territorial law that illegalized advertising, causing, or performing abortions anywhere in Arizona. The 1901 code, in conjunction with the federal Comstock Act, regulated the advertisement and accessibility of abortion services and contraceptives in Arizona. The Federal Comstock Act of 1873 had illegalized the distribution of material on contraceptives and abortions through the US Postal Services by labeling contraceptive and abortive material as obscene. After the passage of that federal law, many states and territories, including Arizona, enacted or codified state or territory-level anti-obscenity laws to augment the federal law's effects. Those laws became called Comstock laws, and Arizona's 1901 laws was its Comstock law. The Arizona Comstock law hindered Arizona women's access to abortion services until the mid twentieth century, when state and federal court decisions dismantled Comstock laws nationwide.

Jane Elizabeth Hodgson was a physician who advocated for abortion rights in the twentieth century in the United States. In November of 1970, Hodgson became the first physician in the U.S. to be convicted of performing an illegal abortion in a hospital. Hodgson deliberately performed the abortion to challenge the Minnesota State Statute 617.18, which prohibited non-therapeutic abortions. Following the legalization of abortion in the US Supreme Court case Roe v. Wade (1973), Hodgson focused on promoting accessible abortion, obstetric, and gynecological care throughout Minnesota. Her name also appears in the Supreme Court case Hodgson v. Minnesota (1990), which challenged the constitutionality of a Minnesota statute that required physicians to notify both parents forty-eight hours prior to a minor being allowed to undergoing an abortion. Hodgson’s career was centered around challenging the legal system to protect and promote reproductive rights for women, including access to abortion.

James Marion Sims developed a surgical cure for ruptures of the wall separating the bladder from the vagina during labor, ruptures called vesico-vaginal fistulas, and he developed techniques and tools used to improve reproductive examinations and health care for women in the US during the nineteenth century. Sims's lateral examination position allowed doctors to better see the vaginal cavity, and his speculum, a spoon-like object used for increased view into the vagina, helped to make gynecological examinations more thorough. Sims helped ease the physical and social strains of post-birth women who suffered from vesico-vaginal fistulas, and he established the first hospital in New York City, New York, dedicated solely to treating women and improving women's health care.

Horatio Robinson Storer was a surgeon and anti-abortion activist in the 1800s who worked in the field of women’s reproductive health and led the Physicians’ Crusade Against Abortion in the US. Historians credit Storer as being one of the first physicians to distinguish gynecology, the study of diseases affecting women and their reproductive health, as a separate subject from obstetrics, the study of pregnancy and childbirth. Storer was one of the first physicians to successfully perform a Caesarian section, or the removal of the fetus through a surgical incision, followed by the removal of the woman’s uterus, a procedure which would later be known as Porro’s operation. Storer was also an anti-abortion activist who believed that public attitudes toward abortion were too relaxed and that the laws did not effectively punish what he deemed to be the criminal act of abortion. Historians credit Storer with leading the Physicians’ Crusade Against Abortion, which they consider largely responsible for the increase in laws criminalizing abortion in the late 1800s.

Vincenz Czerny was a surgeon in the nineteenth century who specialized in cancer and women’s surgical care. Czerny performed one of the first breast augmentations using a reconstruction method to correct asymmetry and disfigurement of a woman’s breasts. Additionally, Czerny improved the safety and efficacy of existing operations, such as the vaginal hysterectomy, which involves the surgical removal of some or all of a woman’s reproductive structures. He contributed to other surgeries involving the esophagus, kidneys, and intestines. He was also one of the first individuals to research alternative methods of cancer treatment and founded the Institut für Experimentelle Krebsforschung (Institute for Experimental Cancer Research), in Heidelberg, Germany. The institute became one of the first hospitals dedicated solely to the study of cancer. Czerny’s development of the breast augmentation and vaginal hysterectomy, as well as his cancer research, helped shape the creation of modern-day surgical procedures.

James Marion Sims developed a treatment for vesico-vaginal fistulas in Montgomery, Alabama in the 1840s. Vesico-vaginal fistulas were a relatively common condition in which a woman's urine leaked into her vaginal cavity from her bladder, and many regarded the fistulas as untreatable during the early 1800s. After years of efforts to repair the fistulas with myriad tools, techniques, and procedures, Sims developed the speculum and a vaginal examination position later named for him. He also popularized the use of silver metal sutures to treat and cure women who had vesico-vaginal fistulas. Sims's surgical cure for vesico-vaginal fistulas eased both the social stigma and physical discomfort of many affected women. Though current treatments of vesico-vaginal fistulas have evolved since the nineteenth century, some of the basic principles utilized by Sims have been incorporated into present-day surgeries. In particular, Sims stressed the significance of continual bladder drainage after the operation.

On 1 July 1976, the US Supreme Court decided in the case Planned Parenthood v. Danforth that provisions of a Missouri law regulating abortion care were unconstitutional. That law, House Bill 1211, restricted abortion care by requiring written consent for each abortion procedure from the pregnant woman as written consent of the woman’s husband if she was married, or the written consent of her parents if she was unmarried and younger than eighteen. House Bill 1211 also required that physicians make efforts to preserve the lives of aborted fetuses. Following the passage of House Bill 1211 in 1974, two physicians and Planned Parenthood of Central Missouri challenged the law. Following the decisions by several lower courts, the US Supreme Court ruled on the case. The US Supreme Court struck down parts of a law that violated the US Constitution and the prior court case Roe v. Wade, and in doing so, they expanded access to abortion care in the US.

In the 1936 case United States v. One Package of Japanese Pessaries, the US Court of Appeals for the Second Circuit in New York City, New York, confirmed that physicians had the right to distribute contraceptives to patients for medical purposes. In January 1933, US Customs confiscated a package of contraceptives imported from Japan by US physician Hannah Stone. They claimed that the package violated section 305 of the Tariff Act of 1930, which, like the 1873 anti-obscenity Comstock Act, granted the US government authority to seize contraceptive materials imported into the country or sent through the mail. The court ruled that US Customs was not justified in confiscating the package and ordered its return to Stone. United States v. One Package exempted physicians from the restrictions surrounding the distribution of contraceptives and contributed to the subsequent dismantling of the Comstock Act in later court cases.
