Embryo screening technologies offer important benefits to individuals who use them and society. These techniques can expand the reproductive options of many prospective parents and can contribute to reducing the burdens of disease and disability. Nonetheless, embryo screening techniques present individuals and societies with important ethical challenges. Here, I explore some of them. In particular, I discuss the costs for prospective parents of increased reproductive choices, as well as concerns about sanctioning problematic social norms, increasing social injustice, limiting the ways (...) societies can tackle diseases and disabilities, and promoting the commodification of children.

To what extent should parents be allowed to use reproductive technologies to determine the characteristics of their future children? Is there something morally wrong with choosing what their sex will be, or with trying to 'screen out' as much disease and disability as possible before birth? Stephen Wilkinson offers answers to such questions.

The UK Human Fertilisation and Embryology Authority was right to permit tissue typing preimplantation genetic diagnosisOn July 21 2004, the Human Fertilisation and Embryology Authority , Britain’s regulatory agency for reproductive technologies, revised its policy on preimplantation genetic diagnosis for tissue typing.1,2 The authority of the HFEA to enact such a policy was affirmed by the UK’s highest court, the House of Lords, on April 28 2005.3 Preimplantation genetic diagnosis combines in vitro fertilisation with genetic testing. In PGD, embryos generally (...) undergo biopsy prior to the eight cell stage, followed by genetic testing for a particular trait. Tissue typing PGD is done to identify an embryo that is tissue matched for a child suffering from a severe disease requiring bone marrow or cord blood stem cell transplantation and for whom no living donor exists. This procedure was first performed in 2000.4 Precise matching of tissue types is critical to successful tissue transplant, and the donors of such tissues are often referred to as “saviour siblings”.Where a tissue matched individual already exists, extracting bone marrow from that individual or collecting cord blood already in storage, rather than creating a match, presents the most immediate treatment alternative. Bone marrow donation from adults or other medically competent individuals is not generally ethically contested, and bone marrow donation from medically incompetent individuals is also permissible under certain conditions.5 Where no living tissue donor exists, however, intentionally creating a donor through tissue typing PGD is among a short list of possible treatment options.The July HFEA policy change makes PGD licensable in cases where tissue typing is the only purpose of testing. Previously, PGD was licensable in the UK only for disease testing, and tissue typing PGD was permissible only when …. (shrink)

This is a major new study of Kant's ethics that will transform the way students and scholars approach the subject in future. Allen Wood argues that Kant's ethical vision is grounded in the idea of the dignity of the rational nature of every human being. Undergoing both natural competitiveness and social antagonism the human species, according to Kant, develops the rational capacity to struggle against its impulses towards a human community in which the ends of all are to harmonize and (...) coincide. The distinctive features of the book are twofold. First, it focuses for the first time on the central role played in Kant's ethical theory by the value of rational nature as an end itself. Second, it shows the importance of Kant's systematic theory of human nature and history, and its implications for the structure, formulation, and application of Kant's moral principles. This comprehensive study will be of critical importance to students of moral philosophy, the history of ideas, political theory, and religious studies. (shrink)

While pre-implantation genetic diagnosis is available and legal in Malaysia, there is an ongoing controversy debate about its use. There are few studies available on individuals’ attitudes toward PGD, particularly among those who have a genetic disease, or whose children have a genetic disease. To the best of our knowledge, this is, in fact, the first study of its kind in Malaysia. We conducted in-depth interviews, using semi-structured questionnaires, with seven selected potential PGD users regarding their knowledge, attitudes and decisions (...) relating to the use PGD. The criteria for selecting potential PGD users were that they or their children had a genetic disease, and they desired to have another child who would be free of genetic disease. All participants had heard of PGD and five of them were considering its use. The participants’ attitudes toward PGD were based on several different considerations that were influenced by various factors. These included: the benefit-risk balance of PGD, personal experiences of having a genetic disease, religious beliefs, personal values and cost. The study’s findings suggest that the selected Malaysian participants, as potential PGD users, were supportive but cautious regarding the use of PGD for medical purposes, particularly in relation to others whose experiences were similar. More broadly, the paper highlights the link between the participants’ personal experiences and their beliefs regarding the appropriateness, for others, of individual decision-making on PGD, which has not been revealed by previous studies.

By using tissue typing in conjunction with preimplantation genetic diagnosis doctors are able to pick a human embryo for implantation which, if all goes well, will become a “saviour sibling”, a brother or sister capable of donating life-saving tissue to an existing child.This paper addresses the question of whether this form of selection should be banned and concludes that it should not. Three main prohibitionist arguments are considered and found wanting: the claim that saviour siblings would be treated as commodities; (...) a slippery slope argument, which suggests that this practice will lead to the creation of so-called “designer babies”; and a child welfare argument, according to which saviour siblings will be physically and/or psychologically harmed.

Genetic screening technologies involving pre-implantation genetic diagnosis raise particular issues about selective reproduction and the welfare of the child to be born. How does selection impact on the identity of the child who is born? Are children who are selected for a particular purpose harmed or treated as commodities? How far should the state interfere with parents' reproductive choices? Currently, concerns about the welfare of the child in selective reproduction have focused on the individual interests of the child to be (...) born. This book re-evaluates the welfare of the child through the controversial topic of saviour sibling selection. Drawing on relational feminist and communitarian ethics, Michelle Taylor-Sands argues that the welfare of the child to be born is inextricably linked with the welfare of his/her family. The author proposes a relational model for selective reproduction based on a broad conception of the welfare of the child that includes both individual and collective family interests. By comparing regulation in the UK and Australia, the book maps out how law and policy might support a relational model for saviour sibling selection. With an interdisciplinary focus, Saviour Siblings: A Relational Approach to the Welfare of the Child in Selective Reproduction will be of particular interest to academics and students of bioethics and law as well as practitioners and policymakers concerned with the ethics of selective reproduction.

Pre-Implantation Genetic Diagnosis represents the first fusion of genomics and assisted reproduction and the first reproductive technology that allows prospective parents to screen and select the genetic characteristics of their potential offspring. However, for some, the idea that we can intervene in the mechanisms of human existence at such a fundamental level can be, at a minimum, worrying and, at most, repugnant. Religious doctrines particularly are likely to collide with the rapidly advancing capability for science to make such interventions. This (...) paper focuses on opinions and arguments of selected religious scholars regarding ethical issues pertaining to PGD. In-depth interviews were conducted with religious scholars from three different religious organizations in the Klang Valley, Malaysia. Findings showed that Christian scholars are very sceptical of the long-term use of PGD because of its possible effect on the value of humanity and the parent-children relationship. This differs from Islamic scholars, who view PGD as God-given knowledge in medical science to further help humans understand medical genetics. For Buddhist scholars, PGD is considered to be new medical technology that can be used to save lives, avoid suffering, and bring happiness to those who need it. Our results suggest that it is important to include the opinions and views of religious scholars when it comes to new medical technologies such as PGD, as their opinions will have a significant impact on people from various faiths, particularly in a multi-religious country like Malaysia where society places high value on marital relationships and on the traditional concepts of family.
