The "Humanae Vitae," meaning "Of Human Life" and subtitled "On the Regulation of Birth," was an encyclical promulgated in Rome, Italy, on 25 July 1968 by Pope Paul VI. This encyclical defended and reiterated the Roman Catholic Church's stance on family planning and reproductive issues such as abortion, sterilization, and contraception. The document continues to have a controversial reputation today, as its statements regarding birth control strike many Catholics as unreasonable.

The principal work of St. Thomas Aquinas, the Summa Theologica is divided into three parts and is designed to instruct both beginners and experts in all matters of Christian Truth. It discusses topics central to Christian morality, ethics, law, and the life of Christ, providing philosophical and theological solutions to common arguments and questions surrounding the Christian faith. The views presented in this body of writing are currently upheld in large part by the modern doctrines of the Roman Catholic Church. Interesting references to and insights on ensoulment and embryology, as well as other topics discussed in Summa Theologica, indicate a strong Aristotelian and Augustinian influence.

Eclipse of Reason is a 1987 anti-abortion documentary film directed, filmed, and narrated by Bernard Nathanson, an obstetrician in the US. American Portrait Films released the film in 1987 featuring Nathanson’s commentary and footage of an abortion of a four-month-old fetus. The film also featured the testimony of women who had suffered following similar procedures. In Eclipse of Reason, Nathanson equates the fetus to a person, likening abortion procedures to murder and arguing for the illegalization of abortion. This documentary was a sequel to Nathanson’s first documentary film, The Silent Scream released in 1984. Both documentaries argued for illegalizing abortion, which had been decriminalized in 1973 in the United States. Eclipse of Reason was one of the most influential films that garnered public attention to the abortion debate in the US during the 1980s.

Barry Morris Goldwater was a Republican Arizona Senator and US presidential candidate in the twentieth-century whose policies supported the women's reproductive rights movement. Goldwater, a businessman and Air Force reservist, transitioned into politics in the 1950s. He helped align popular support for a conservative Republican Party in the 1960s. Throughout his life, he worked to maintain personal liberty and to limit governmental intrusion into citizens' private lives. Goldwater, influenced by his wife Margaret (Peggy) Goldwater, supported women's rights to abortions. Goldwater's advocacy and support for reproductive rights assisted in the foundation of the Planned Parenthood chapter in Phoenix, Arizona, and for national policies promoting birth control and abortion rights.

From 1977 to 1987, Harald zur Hausen led a team of researchers across several institutions in Germany to investigate whether the human papillomavirus (HPV) caused cervical cancer. Zur Hausen's first experiment tested the hypothesis that HPV caused cervical cancer rather than herpes simplex virus type 2 (HSV-2), the then accepted cause. His second and third experiments detailed methods to identify two previously unidentified HPV strains, HPV 16 and HPV 18, in cervical cancer tumor samples. The experiments showed that HPV 16 and 18 DNA were present in cervical tumor samples. Zur Hausen concluded that HPV, not HSV-2, caused cervical cancer, which enabled researchers to develop preventions, such as the HPV vaccine.

Emmett McLoughlin wrote People's Padre: An Autobiography, based on his experiences as a Roman Catholic priest advocating for the health of people in Arizona. The Beacon Press in Boston, Massachusetts, published the autobiography in 1954. McLoughlin was a Franciscan Order Roman Catholic priest who advocated for public housing and healthcare for the poor and for minority groups in Phoenix, Arizona, during the mid twentieth century. The autobiography recounts McLoughlin's efforts in founding several community initiatives throughout Phoenix, including the St. Monica's Community Center, later renamed St. Pius X Catholic Church, the Phoenix housing projects, and St. Monica's Hospital, later renamed Phoenix Memorial Hospital. McLoughlin's autobiography discusses his advocacy for people to have greater access to maternity and prenatal healthcare, to testing and treatment for sexually transmitted infections, and to birth control in the Phoenix area.

Walter Schiller studied the causes of diseases in the US and Austria in the early twentieth century and in 1928, invented the Schiller test, or a way to diagnose early cervical cancer in women. Cervical cancer is the uncontrollable division of cells in the cervix, or lower part of the uterus. While living in Austria until his emigration to escape the Nazis in 1937, Schiller concluded that there was a form of cervical cancer, later named carcinoma in situ, that physicians could detect earlier than when tumors start to appear. To determine whether women exhibited that early form of cancer, Schiller stained women’s cervixes with a type of iodine that would stain healthy cervical tissue and not cancerous cervical tissue. Cervical cancer is more deadly to women when it is caught later in its progression, and was difficult to detect in Schiller's time. Schiller’s research enabled physicians to diagnose cervical cancer early, helping women receive treatment quicker and ultimately helping to popularize annual diagnostic exams in the US.

In 1913, journalist Samuel Hopkins Adams published “What Can We Do About Cancer? The Most Vital and Insistent Question in the Medical World,” hereafter “What Can We Do About Cancer,” in Ladies’ Home Journal. Cancer is a disease that is the result of abnormal cell division in different parts of the body, such as the breasts or the cervix. During that time, many women did not discuss or disclose early symptoms of reproductive cancers, such as breast lumps and abnormal vaginal discharge, out of shame or disgust. Thus, people often considered cancer to be a taboo topic. “What Can We Do About Cancer?” provides a representation of what people in the early 1900s thought to be the early warning signs of cancer in women. Although, as of 2021, researchers have made advancements that have increased the scientific understanding of cancer and how it develops, Adams’ article provided women in the US during the 1900s with recommendations on early methods of cancer detection.

"Casti Connubii," a papal encyclical given by Pope Pius XI on 31 December 1930, served primarily as a reaffirmation and expansion of the issues discussed in Arcanum, an encyclical written by Pope Leo XIII. It was released to address new threats to marriage and conjugal unity, and indeed is translated "On Christian Marriage" or "On Chastity in Marriage." The document explores the meaning of Christian marriage and emphasizes its threefold purpose as borrowed from St. Augustine: to produce offspring, to grow in conjugal faith, and to show benefit from the sacrament. It begins by exploring the nature of marriage, followed by a discussion of its advantages for individuals and societies, erroneous but common beliefs about marriage, threats to pure marriage, and finally how to address them. Included in the threats to pure marriage is that of the growing popularity of contraception and abortive procedures, at which point Pope Pius XI elaborates on the Church' s statement that life begins at conception.

A licensed obstetrician and gynecologist, Pearl Tang worked to improve the health of women and children in Maricopa County, Arizona, during the twentieth and twenty-first centuries. Her work with the Maricopa County Health Department ranged from immunizations to preventing cervical cancer. Tang obtained federal grants and community support to establish various child and maternal health clinics throughout Maricopa County as chief of the Maricopa County Bureau of Maternal and Child Health. Tang established mobile clinics, including a clinic she called the Maternity Care Bus, to address the lack of access to medical care among rural women in Arizona. She also focused on family planning through education and the distribution of contraception. Tang's efforts in Maricopa Country increased the delivery of maternal, child, and family planning care and helped lower Arizona's infant mortality rate.
