Savior Siblings and the Ethics of Preimplantation Genetic Diagnosis
This paper examines the ethical and moral controversies surrounding preimplantation genetic diagnosis (PGD) when used to create "savior siblings" — children conceived and selected to provide HLA-compatible stem cells or tissue to a critically ill brother or sister. The paper traces PGD's origins, outlines the diseases that make such procedures medically necessary, and surveys competing ethical positions on embryo selection, the moral status of embryos, and the psychological welfare of the donor child. Real-world cases, including the Whitaker and Hashmi families in the United Kingdom, illustrate how policy, law, and ethics intersect. The paper also discusses the unique role nurses play in supporting and assessing families who pursue this process.

What makes this paper effective
- The paper draws on multiple peer-reviewed sources and real case studies — the Whitaker and Hashmi families — to ground abstract ethical arguments in concrete, human situations.
- It presents opposing viewpoints fairly, giving space to both supporters and critics of savior sibling creation, which strengthens its analytical credibility.
- The conclusion connects the ethical debate to the specific professional role of nurses, giving the paper a clear disciplinary focus and practical takeaway.
Key academic technique demonstrated
The paper uses a multi-perspective ethical analysis framework, systematically presenting deontological concerns (the child as an end versus a means), consequentialist arguments (saving 330,000 children annually), and virtue-based reasoning (the character of loving parents). This layered approach allows the author to show that no single ethical lens resolves the dilemma, reflecting mature academic reasoning about contested bioethical questions.
Structure breakdown
The paper opens with a definition and history of PGD, then moves through escalating levels of controversy — from general ethical debate, to specific moral objections about embryo status, to the medical necessity argument. Real-world UK policy cases provide applied examples. The conclusion synthesizes the tension and introduces the nurse's professional responsibility, bookending the clinical framing established at the outset.
Introduction
This paper addresses the ethical issues that arise when parents undergo a procedure to conceive a child who will perfectly match the blood type of an existing sick child, for the purpose of saving that sick child's life. This procedure is known as preimplantation genetic diagnosis (PGD). While it provides hope to desperate parents, it also carries significant ethical implications and concerns.
Preimplantation Genetic Diagnosis
Preimplantation genetic diagnosis is described as an "early form of pre-natal diagnosis and a procedure in which a biopsy is taken from an embryo previously fertilized outside of a woman's womb to determine different characteristics about that embryo prior to in vitro fertilization and implantation" (Fasbender, 2009, p. 17). This procedure was first used in 1989 for the purpose of avoiding "the implantation of an embryo that was affected by a mutation or chromosomal abnormality associated with serious illness" (Fasbender, 2009, p. 17).
Uses for PGD since that time include "family balancing" — that is, choosing the sex of a child — and, more controversially, the creation of a child "who is Human Leukocyte Antigen (HLA)-matched with a preexisting sibling in need of stem cell transplants" (Fasbender, 2009, p. 19). Using the procedure in this manner enables parents to select an embryo free from serious genetic disease while simultaneously selecting for a tissue match, so that the umbilical cord blood of the resulting baby can provide stem cells to treat a seriously ill sibling (Spriggs, 2005, p. 341). Future marrow and tissue donation may also be expected from the donor child, which further intensifies the ethical debate (Fasbender, 2009, pp. 19–20).
