Rosalind Elsie Franklin worked with X-ray crystallography at King's College London, UK, and she helped determine the helical structure of DNA in the early 1950s. Franklin's research helped establish molecular genetics, a field that investigates how heredity works on the molecular level. The discovery of the structure of DNA also made future research possible into the molecular basis of embryonic development, genetic disorders, and gene manipulation.

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.

The San Diego Zoo Institute for Conservation Research (SDZICR) in San Diego, California, is a research organization that works to generate, use, and share information for the conservation of wildlife and their habitats. In 1975, Kurt Benirschke, a researcher at the University of California, San Diego (UCSD) who studied human and animal reproduction, and Charles Bieler, the director of the San Diego Zoo, collaborated to form the Center for Reproduction of Endangered Species (CRES). In 2009, the San Diego Zoo announced the creation of SDZICR, which expanded and replaced CRES, to provide central organization and management of scientific programs at the San Diego Zoo. By 2004, Allison Alberts was the director of research and for more than a decade oversaw the SDZICR's many research initiatives, including the collection and storage of genetic and reproductive information of rare and endangered animal and plant species.

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.

In the late 1990s researchers Yuk Ming Dennis Lo and his colleagues isolated fetal DNA extracted from pregnant woman’s blood. The technique enabled for more efficient and less invasive diagnoses of genetic abnormalities in fetuses, such as having too many copies of chromosomes. Lo’s team published their results in 1997’s “Presence of Fetal DNA in Maternal Plasma and Serum.” The results led to developments of clinical tests that can access fetal genetic information and detect genetic abnormalities before birth without the significant risks that can potentially harm the fetus associated with invasive genetic testing techniques.

In February 1953, Linus Pauling and Robert Brainard Corey, two scientists working at the California Institute of Technology in Pasadena, California, proposed a structure for deoxyribonucleic acid, or DNA, in their article “A Proposed Structure for the Nucleic Acids,” henceforth “Nucleic Acids.” In the article, Pauling and Corey suggest a model for nucleic acids, including DNA, that consisted of three nucleic acid strands wound together in a triple helix. “Nucleic Acids” was published in Proceedings of the National Academy of Sciences shortly after scientists came to the consensus that genes, the biological factors that control how organisms develop, contained DNA. Though scientists proved Pauling and Corey’s model incorrect, “Nucleic Acids” helped scientists understand DNA’s structure and function as genetic material.

Mary-Claire King studied genetics in the US in the twenty-first century. King identified two genes associated with the occurrence of breast cancer, breast cancer 1 (BRCA1) and breast cancer 2 (BRCA2). King showed that mutated BRCA1 and BRCA2 genes cause two types of reproductive cancer, breast and ovarian cancer. Because of King’s discovery, doctors can screen women for the inheritance of mutated BRCA1 and BRCA2 genes to evaluate their risks for breast and ovarian cancer. King also demonstrated the genetic similarities between chimpanzees and humans and helped to identify victims of human rights abuses using genetics. King's identification of the BRCA genes and their relationship to breast and ovarian cancer, both reproductive cancers, has allowed physicians to screen thousands of women for the genes and for those women to choose to undergo preventative cancer treatment to lower their risk of cancer.

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.
