In Davis v. Davis (1992), the Supreme Court of Tennessee decided a dispute over cryopreserved preembryos in favor of Junior Lewis Davis, who sought to have the preembryos destroyed over the objections of his former wife, Mary Sue Davis. The decision in Davis, although not binding in other states, suggested a framework for resolving similar disputes in the US. That framework established that courts should follow the wishes of those who contribute their sperm and egg cells, or gamete providers, to create preembryos. In the event of a dispute, courts should enforce any prior agreement between the gamete providers and in the absence of such an agreement, the court should weigh the interests of the parties, ordinarily ruling in favor of the party who wishes to avoid procreation.

In a dispute over the allocation of cryopreserved preembryos, the Supreme Court of Washington resolved the case of David J. Litowitz v. Becky M. Litowitz (2002) by reaching a decision that neither party wanted. David Litowitz sought to find adoptive parents for two cryopreserved preembryos created during his marriage to Becky Litowitz when the couple was attempting to have children using in vitro fertilization (IVF). Becky sought to implant the preembryos in a surrogate in an effort to parent a child. In June 2002, the court instead determined that the preembryos should have been destroyed. The court focused on the former couple s written consent agreement signed at the time of their participation in the IVF program, which stated that the preembryos would be destroyed after five years of storage.

In Arizona, statutes that protect persons, such as the wrongful death statute, will not be interpreted by the courts to grant personhood status to frozen embryos. The legislature may grant such protection in the statute if it chooses to do so by explicitly defining the word person to include frozen embryos.

In a case of first impression in the state of New York, the highest state court decided that a priori written agreement between progenitors of frozen embryos regarding the disposition of their "pre-zygotes" in the event of divorce is binding. By copying the general result arrived at by the Tennessee Supreme Court in Davis v. Davis in 1992, the New York court magnified the weight of authority in favor of upholding prior written agreements for in vitro fertilization practices.

The Dickey-Wicker Amendment is an amendment attached to the appropriations bills for the Departments of Health and Human Services, Labor, and Education each year since 1996 restricting the use of federal funds for creating, destroying, or knowingly injuring human embryos. The Dickey-Wicker Amendment began as a rider (another name for an amendment) attached to House Resolution (H.R.) 2880. H.R. 2880 was a 1996 appropriations bill sponsored by the head of the House Appropriations Committee, Republican Representative Bob Livingston of Louisiana, for the Department of Health and Human Services titled "The Balanced Budget Downpayment Act, I." Though the appropriations bill's sole sponsor was Representative Livingston, the amendment itself is named for its authors: Representative Jay Dickey, a Republican from Arkansas, and Roger Wicker, a Republican from Mississippi.

A PhD and medical doctor turned ethicist, Leon Kass calls himself an unlicensed humanist. Throughout his unique career he has sought to impact others and engage important cultural issues. This he has accomplished over the course of many years by studying biochemistry, teaching humanities, writing articles and books on ethics, and serving as chair of the President's Council on Bioethics. Kass has become a controversial figure in the field of embryology, having written numerous articles and overseen the publication of several reports on a range of topics including the ethics of cloning, assisted reproduction technology, and human stem cell research.

Human pluripotent stem cells are valued for their potential to form numerous specialized cells and for their longevity. In the US, where a portion of the population is opposed to destruction of human embryos to obtain stem cells, what avenues are open to scientists for obtaining pluripotent cells that do not offend the moral sensibilities of a significant number of citizens? It is this question that the official position paper, or white paper, "Alternative Sources of Human Pluripotent Stem Cells," published in May 2005 by the President's Council on Bioethics under the chairmanship of Leon Kass, seeks to answer. Three experts external to the council, Andrew Fire from the Stanford University School of Medicine, Markus Grompe of the Oregon Health and Science University, and Janet Rossant from the Samuel Lunenfeld Research Institute in Toronto, also reviewed the white paper prior to publication.

Henrietta Lacks, born Loretta Pleasant, had terminal cervical cancer in 1951, and was diagnosed at The Johns Hopkins University in Baltimore, Maryland, where researchers collected and stored her cancer cells. Those cells went on to become the first immortal human cell line, which the researchers named HeLa. An immortal cell line is an atypical cluster of cells that continuously multiply on their own outside of the organism from which they came, often due to a mutation. Lacks’s cancer cells enabled scientists to study human cells outside of the human body, though that was controversial since she did not voluntarily donate her cells for such research. Science writer Rebecca Skloot chronicled Lacks’s life in her book, The Immortal Life of Henrietta Lacks, which became a movie in 2017. Lacks’s HeLa cell line has contributed to numerous biomedical research advancements and discoveries and her story has prompted legal and ethical debates over the rights that an individual has to their genetic material and tissue.

This influential opinion by famed jurist Oliver Wendell Holmes, Jr. was copied by courts throughout the United States. For over sixty years, courts refused to recognize a cause of action on behalf of a child who died before or after birth as a result of injuries suffered in the womb because the fetus was considered legally a part of its mother and thus did not possess personhood. This policy changed after the decision in Bonbrest v. Kotz in 1946.

On 1 October 1995, Steven Epstein published “The Construction of Lay Expertise: AIDS Activism and the Forging of Credibility in the Reform of Clinical Trials,” hereafter “Lay Expertise,” in the journal Science, Technology, & Human Values. In the article, Epstein shows how particular activists in the 1980s helped reform government-run clinical trials for people with acquired immunodeficiency syndrome, or AIDS. Those activists did that work at a time when AIDS was widespread among communities of gay men, and there were no treatments available to combat the disease. Epstein documents how AIDS activists gained credibility in the eyes of the scientific establishment through specific tactics of engagement. “Lay Expertise” laid a foundation for understanding how AIDS movement activism transformed the field of biomedicine, and paved the way for additional research on illness-related social movements, such as those related to infertility and embryonic stem cell research.
