The Human Papillomavirus (HPV) strains 16 and 18 are the two most common HPV strains that lead to cases of genital cancer. HPV is the most commonly sexually transmitted disease, resulting in more than fourteen million cases per year in the United States alone. When left untreated, HPV leads to high risks of cervical, vaginal, vulvar, anal, and penile cancers. In 1983 and 1984 in Germany, physician Harald zur Hausen found that two HPV strains, HPV-16 and HPV-18, caused cervical cancer in women. In the early twenty first century, pharmaceutical companies Merck & Co. and GlaxoSmithKline created HPV vaccines protecting against HPV-16 and HPV-18, which have reduced the number of HPV infections by fifty-six percent in the US. Discovering HPV strains 16 and 18 allowed physicians to test for those cancer-causing cell populations using Pap smears, a diagnostic tool that collects cells from the woman's cervix to identify cancerous cases of HPV infection. By identifying the cancerous strains of HPV-16 and HPV-18 and utilizing preventative measures such as the Pap smear and HPV vaccines, the rates of cervical cancer and other HPV-related cancers have reduced.

Where Are My Children? is an anti-abortion silent film released in the United States on 16 April 1916. The film was directed by Lois Weber and Phillips Smalley and produced by Universal Film Manufacturing Company/Lois Weber Productions in Universal City, California. In the film, Weber tells a story of an attorney who wants to have children and raise a family, but his wife chooses to abort her pregnancies, fearing that having children will ruin her social activities. In the early 1900s, information about contraception was not freely available or legal to obtain. Physicians were allowed to distribute contraceptives only if the woman would be put in a life-threatening circumstance were she to get pregnant. In the film, Weber encourages contraceptives as a means of family planning, but advocates against abortions. Where Are My Children? is one of the first films to discuss birth control and family planning, and it is among the first to push against motion picture censorship of contraception and family planning in cinema.

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.

Gattaca is a 1997 science fiction film produced in the US that depicts a future society that uses reproductive technology and genetic engineering in order to produce genetically enhanced human beings. By selectively choosing certain genes, scientists and physicians ensure that individuals born using reproductive technologies have desirable physical and psychological traits and prevent undesirable traits. The film tells a story of Vincent Freeman, a man conceived without the aid of reproductive technology, who works to overcome his genetic disadvantages compared to his enhanced counterparts in order to achieve his dream of a career in space travel. The film was directed and written by Andrew Niccol and released by Columbia Pictures in Culver City, California, on 24 October 1997. Gattaca addresses the ethical uses of biotechnology, gene manipulation, and genetic engineering, and the film helps illustrate the debate over human genetic engineering research and implications.

Собачье сердце (Heart of a Dog) is a novella written in 1925 by author and playwright Mikhail Bulgakov in Moscow, USSR, later Russia. An early English translation was published in 1968. Heart of a Dog tells the story of a stray dog named Sharik, who is found by a surgeon, and undergoes extensive surgery for experimental purposes to create a New Soviet man, someone committed to the ideals of communism in the Soviet Union. In Heart of a Dog, Bulgakov satirizes the communist revolution in the Soviet Union and the concept of a New Soviet man, and criticizes the science and practice of eugenics.

Tomorrow's Children is a film that tells the story of Alice Mason, a young woman whom the US government forcibly sterilizes because she comes from a family with a history of alcoholism, mental illnesses, and physical disabilities, traits that they considered biologically determined and inferior. The film, released in 1934, was directed by Crane Wilbur, produced by Bryan Foy, written by Wilbur and Wallace Thurman, and released by Foy Productions Ltd. Tomorrow's Children criticized forced sterilization and the eugenics movement in the United States in addition to protesting film censorship regulations in the early 1900s.

In 2017, Julie Carré, Nicolas Gatimel, Jessika Moreau, Jean Parinaud, and Roger Léandri published “Does Air Pollution Play a Role in Infertility?: a Systematic Review,” hereafter “Does Air Pollution Play a Role,” in the journal Environmental Health. The authors completed a systematic literature review to investigate the effects of air pollutants on fertility in exposed populations. Since air quality has an impact on overall health as well as on reproductive function, the authors sought to increase the awareness of the importance of environmental protection issues among the general public and the authorities. The article “Does Air Pollution Play a Role” provided the foundation for further research on how air pollution can contribute to low reproductive capacity in areas with high exposure.

In September 2003, Robert L. Goldenberg and Cortney Thompson published the article “The Infectious Origins of Stillbirth” in the American Journal of Obstetrics and Gynecology. In the article, the authors conducted a literature review of articles from the US National Library of Medicine database to review the relationship between perinatal infections, which are infections around the time of birth, and the occurrence of stillbirth. Stillbirth is the death of a fetus in the uterus after at least twenty weeks of pregnancy. Infectious disease can cause or increase the risk of stillbirth in several ways, by causing illness in the pregnant person, damaging the placenta, or directly infecting the fetus. Infectious agents can be viruses, bacteria, or protozoa. Rates of infectious disease and stillbirth are both higher in developing than in developed countries, and the authors state that stillbirth due to infectious disease is also higher. “The Infectious Origins of Stillbirth” provides a comprehensive review of the information available on how infections can lead to stillbirth, providing a foundation for further research.

The Boys from Brazil is a science fiction film based on the novel of the same name by Ira Levin about an underground neo-Nazi society in South America trying to clone Adolf Hitler, the dictator of Nazi Germany during World War II, to restore the Nazi movement. The film was directed by Franklin Schaffner and released in 1978 by 20th Century Fox in Los Angeles, California. The Boys from Brazil is a film that was one of the first films to depict cloning, and to discuss the ethical implications of genetic engineering, cloning, and eugenics.

In 2017, Laura Geer and colleagues published the results of a study investigating the effects of parabens and antimicrobial compounds on birth outcomes in the article “Association of Birth Outcomes with Fetal Exposure to Parabens, Triclosan and Triclocarban in an Immigrant Population in Brooklyn, New York” in the Journal of Hazardous Materials. Parabens are a class of preservatives found in cosmetic and pharmaceutical products and antimicrobial compounds are compounds that kill microorganisms such as bacteria. In the University Hospital of Brooklyn’s Prenatal Clinic in New York City, New York, the authors tested the concentration of parabens and certain antimicrobial substances in pregnant women’s urine and umbilical cord blood plasma, finding that the concentration of one of the substances, triclocarban, may affect many health outcomes for the developing fetus. The authors’ results demonstrate how some common consumer products, in large quantities, may have harmful reproductive effects and birth outcomes.
