Two genetic technologies capable of making heritable changes to the human genome have revived interest in, and in some quarters a very familiar panic concerning, so-called germline interventions. These technologies are: most recently the use of CRISPR/Cas9 to edit genes in non-viable IVF zygotes and Mitochondrial Replacement Therapy the use of which was approved in principle in a landmark vote earlier this year by the United Kingdom Parliament. The possibility of using either of these techniques in humans has encountered the (...) most violent hostility and suspicion. However it is important to be aware that much of this hostility dates back to the fears associated with In Vitro Fertilization and other reproductive technologies and by cloning; fears which were baseless at the time concerning both IVF and cloning the use of both of which have proved to be highly beneficial to humanity and which have been effectively regulated and controlled. This paper argues that CRISPR should by pursued through res.. (shrink)

This paper aims to argue for the thesis that it is not a priori morally justified that the first phase of space colonisation is based on sexual reproduction. We ground this position on the argument that, at least in the first colonisation settlements, those born in space may not have a good chance of having a good life. This problem does not depend on the fact that life on another planet would have to deal with issues such as solar radiation (...) or with the decrease or entire absence of the force of gravity. These issues could plausibly be addressed given that the planets or settlements we will feasibly colonise could be completely transformed through geoengineering processes. Likewise, the ability of humans to live in space could be enhanced through genetic modification interventions. Even if, however, the problems concerning survival in space were solved, we think that, at least in the first period of colonisation of space or other planets, giving birth to children in space could be a morally irresponsible choice since we argue, the life we ​​could give them might not be good enough. We contend that this is the case since when we decide to have a baby. We argue that it is not morally right to be content that our children have a minimally sufficient life worth living; before we give birth to children in space, we should make sure we can give them a reasonable chance of having a good life. This principle applies both on Earth - at least where you can choose - and for space travel. (shrink)

Mitochondrial replacement techniques are designed to allow couples to have children without passing on mitochondrial diseases. Recently, Giulia Cavaliere and César Palacios-González argued that prospective parents have the right to use MRTs to pursue genetic relatedness, such that some same-sex couples and/or polygamous triads could use the process to impart genetic relatedness between a child and more of its caregivers. Although MRTs carry medical risks, Cavaliere and Palacios-González contend that because MRTs are identity-affecting, they do not cause harm to an (...) existing human being, and our intuitions otherwise arise from the non-identity problem. Here, I review several attempts to address the non-identity problem, and propose a solution to the problem. Furthermore, I argue that regardless of one’s stance on whether MRTs are identity-affecting, the use of MRTs to pursue genetic relatedness alone falls outside the scope of the medical profession, as they involve substantive medical risk for no medical benefit.

Rethinking Reprogenetics by Immaculada de Melo-Martin has at its heart a desire to spark discussion about the foundations of our right to reproduce. While many of the arguments are familiar in feminist ethics, de Melo-Martin's text is a useful addition in that she is focusing on the development and application of genetic technology toward reproductive ends, including the ends of transhumanism. Particularly, de Melo-Martin is skeptical about claims that genetic reproduction is a need or right deserving of social resources. This (...) is particularly an issue when genetic reproduction requires public resources to do it or as a consequence of it. She raises questions about whether the desire to have genetically related... (shrink)

In this paper, we argue that lesbian couples who wish to have children who are genetically related to both of them should be allowed access to mitochondrial replacement techniques (MRTs). First, we provide a brief explanation of mitochondrial diseases and MRTs. We then present the reasons why MRTs are not, by nature, therapeutic. The upshot of the view that MRTs are non-therapeutic techniques is that their therapeutic potential cannot be invoked for restricting their use only to those cases where a (...) mitochondrial DNA disease could be ‘cured’. We then argue that a positive case for MRTs is justified by an appeal to reproductive freedom, and that the criteria to access these techniques should hence be extended to include lesbian couples who wish to share genetic parenthood. Finally, we consider a potential objection to our argument: that the desire to have genetically related kin is not a morally sufficient reason to allow lesbian couples to access MRTs. (shrink)

Some Comments on de Melo-Martin and Harris.

Mitochondrial replacement techniques (MRTs) are a new group of biotechnologies that aim to aid women whose eggs have disease-causing deleteriously mutated mitochondria to have genetically related healthy children. These techniques have also been used to aid women with poor oocyte quality and poor embryonic development, to have genetically related children. Remarkably, MRTs create humans with DNA from three sources: nuclear DNA from the intending mother and father, and mitochondrial DNA from the egg donor. In a recent publication Françoise Baylis argued (...) that MRTs are detrimental for genealogical research via mitochondrial DNA because they would obscure the lines of individual descent. In this paper, I argue that MRTs do not obscure genealogical research, but rather that MRT-conceived children can have two mitochondrial lineages. I argue for this position by showing that MRTs are reproductive in nature and, thus, they create genealogy. (shrink)

If bioethical questions cannot be resolved in a widely acceptable manner by rational argument, and if they can be regulated only on the basis of political decision-making, then bioethics belongs to the political sphere. The particular kind of politics practiced in any given society matters greatly: it will determine the kind of bioethical regulation, legislation, and public policy generated there. I propose approaching bioethical questions politically in terms of decisions that cannot be “correct” but that can be “procedurally legitimate.” Two (...) procedures in particular can deliver legitimate bioethical decisions, once combined: expert bioethics committees and deliberative democracy. Bioethics so understood can exceed bioethics as a moral project or as a set of administrative principles to regulate medical practice; it can now aspire to a democratic project that involves ordinary citizens as far as reasonably possible. I advance this argument in four steps: (1) using the example of human germline gene editing, (2) I propose a general understanding of proceduralism, and (3) then combine two types and (4) conclude with a defense of majoritarian proceduralism. I develop this argument in terms of one example: germline gene editing. (shrink)

The CRISPR system for gene editing can break, repair, and replace targeted sections of DNA. Although CRISPR gene editing has important therapeutic potential, it raises several ethical concerns. Some bioethicists worry CRISPR is a prelude to a dystopian future, while others maintain it should not be feared because it is analogous to past biotechnologies. In the scientific literature, CRISPR is often discussed as a revolutionary technology. In this paper we unpack the framing of CRISPR as a revolutionary technology and contrast (...) it with framing it as a value-threatening biotechnology or business-as-usual. By drawing on a comparison between CRISPR and the Ford Model T, we argue CRISPR is revolutionary as a product, process, and as a force for social change. This characterization of CRISPR offers important conceptual clarity to the existing debates surrounding CRISPR. In particular, conceptualizing CRISPR as a revolutionary technology structures regulatory goals with respect to this new technology. Revolutionary technologies have characteristic patterns of implementation, entrenchment, and social impact. As such, early identification of technologies as revolutionary may help construct more nuanced and effective ethical frameworks for public policy. (shrink)

A new reprogenetic technology, mitochondrial replacement, is making its appearance and, unsurprisingly given its promise to wash off our earthly stains --or at least the scourges of sexual reproduction--, John Harris finds only reasons to celebrate this new scientific feat.1 In fact, he finds mitochondrial replacement techniques (MRTs) so “unreservedly welcome” that he believes those who reject them suffer from “a large degree of desperation and not a little callousness.”2 Believing myself to be neither desperate nor callous, but finding myself (...) also no closer at all – not even after reading his article—to following Harris in welcoming these technologies wholeheartedly, it seems appropriate to respond.

Children created through mitochondrial replacement techniques (MRTs) are commonly presented as possessing 50% of their mother’s nuclear DNA, 50% of their father’s nuclear DNA and the mitochondrial DNA of an egg donor. This lab-engineered genetic composition has prompted two questions: Do children who are the product of an MRT procedure have threegeneticparents? And, do MRT egg donors have parental responsibilities for the children created? In this paper, I address the second question and in doing so I also address the first (...) one. First, I present a brief account of mitochondrial diseases and MRTs. Second, I examine how MRTs affect the numerical identity of eggs and zygotes. Third, I investigate two genetic accounts of parenthood and MRT egg donation. Fourth, I explore three causal accounts of parenthood and MRT egg donation. My conclusion is that, under the appropriate circumstances, MRT egg donors are parentally responsible for the children created under genetic accounts of parenthood and under causal accounts of parenthood.

BackgroundHuman genome editing technologies offer much potential benefit. However, central to any conversation relating to the application of such technologies are certain ethical, legal, and social difficulties around their application. The recent misuse, or inappropriate use, by certain Chinese actors of the application of genome editing technologies has been, of late, well noted and described. Consequently, caution is expressed by various policy experts, scientists, bioethicists, and members of the public with regard to the appropriate use of human germline genome editing (...) and its possible future effect on future generations.Main textAs concerns about the applications of heritable genome editing have grown, so too have the questions around what is to be done to curtail ‘rogue actors’. This paper explores various ways in which to regulate genomic editing that are socially beneficial, while being cognisant of legal and ethical principles and rights values. This is done by evolving regulatory frameworks across jurisdictions in an attempt to raise issues, address common principles, and set responsible standards for stewardship of the novel technology.ConclusionsIt is suggested that robust and concrete regulatory measures be introduced that are culturally and contextually sensitive, inclusive, appropriate, and trustworthy – and are based on public empowerment and human rights objectives. Doing so will ensure that we are perfectly positioned to harness and promote the benefits that novel technologies have to offer, while safeguarding public health and curtailing the ambitions of rogue actors. This it is acknowledged is no easy task, so, as a point of departure, this paper sets out a path forward by means of certain, practical recommendations – by constructing genome editing regulation in a manner that both fulfils the desire to better progress human health and that can withstand legal and ethical scrutiny.The following observations and recommendations are made: Firstly, that a solution of effective, legitimate governance should consist of a combination of national and supranational legislative regulation or ‘hard’ law, in combination with ‘soft’ ethics, firmly anchored in and underpinned by human rights values. Second, that efforts to support legal and ethical solutions should be rigorous, practical, and robust, contribute to a reaffirmation of human rights in a contextually sensitive manner, and be transnational in reach. Lastly, that greater harmonisation across jurisdictions and increased public engagement be sought. This it is proposed will address the question of how to implement a normative framework which in turn can prevent future rogue actors. (shrink)

Following the Second Summit on Human Gene Editing in Hong Kong in 2018, where the birth of two girls with germline genome editing was revealed, the need for a responsible pathway to the clinical application of human germline genome editing has been repeatedly emphasised. This paper aims to contribute to the ongoing discussion on research ethics issues in germline genome editing by exploring key issues related to the initial applications of CRISPR in reproductive medicine. Following an overview of the current (...) discussion on bringing germline genome editing into clinical practice, we outline the specific challenges associated with such interventions and the features that distinguish them from conventional clinical testing of new medical treatments. We then review proposed ethical requirements for initial heritable genome editing, such as the absence of reasonable alternatives, the existence of sufficient and reliable preclinical data, appropriate informed consent, requirements related to safety, and long-term follow-up.

Current advances in assisted reproductive technologies aim to promote the health and well-being of future children. They offer the possibility to select embryos with the greatest potential of being born healthy (eg, preimplantation genetic testing) and may someday correct faulty genes responsible for heritable diseases in the embryo (eg, human germline genome modification (HGGM)). Most laws and policy statements surrounding HGGM refer to the notion of ‘serious’ as a core criterion in determining what genetic diseases should be targeted by these (...) technologies. Yet, this notion remains vague and poorly defined, rendering its application challenging and decision making subjective and arbitrary. By way of background, we begin by briefly presenting two conceptual approaches to ‘health’ and ‘disease’: objectivism (ie, based on biological facts) and constructivism (ie, based on human values). The basic challenge under both is sorting out whether and to what extent social and environmental factors have a role in helping to define what qualifies as a ‘serious’ disease beyond the medical criteria. We then focus on how a human rights framework (eg, right to science and right to the highest attainable health) could integrate the concepts of objectivism and constructivism so as to provide guidance for a more actionable consideration of ‘serious’. Ultimately, it could be argued that a human rights framework, by way of its legally binding nature and its globally accepted norms and values, provides a more universal foundation for discussions of the ethical, legal and social implications of emerging or disruptive technologies.

This paper explores the ethics of introducing genome-editing technologies as a new reproductive option. In particular, it focuses on whether genome editing can be considered a morally valuable alternative to preimplantation genetic diagnosis (PGD). Two arguments against the use of genome editing in reproduction are analysed, namely safety concerns and germline modification. These arguments are then contrasted with arguments in favour of genome editing, in particular with the argument of the child’s welfare and the argument of parental reproductive autonomy. In (...) addition to these two arguments, genome editing could be considered as a worthy alternative to PGD as it may not be subjected to some of the moral critiques moved against this technology. Even if these arguments offer sound reasons in favour of introducing genome editing as a new reproductive option, I conclude that these benefits should be balanced against other considerations. More specifically, I maintain that concerns regarding the equality of access to assisted reproduction and the allocation of scarce resources should be addressed prior to the adoption of genome editing as a new reproductive option.

Der weltweit erste Mitochondrien-Transfer, auch als Erzeugung eines „Drei-Eltern-Kindes“ bezeichnet, hat 2016 eine intensive Debatte ausgelöst. Hinsichtlich des Verfahrens, das bisher nur in Großbritannien zugelassen ist, werden auch verschiedene ethische Aspekte angesprochen. Dazu gehören die Risikoabwägung, die reproduktive Selbstbestimmung und die psychosoziale Entwicklung eines Kindes, das von drei Individuen abstammt. Dabei fällt auf, dass zentrale konzeptuelle Fragen hinsichtlich des Mitochondrien-Transfers nicht geklärt sind. Ist der Mitochondrien-Transfer eine genetische Intervention in die Keimbahn? Handelt es sich bei dem Verfahren um eine medizinisch (...) indizierte Therapie oder um eine elektive Behandlung assistierter Reproduktion? Welche Konzepte von Identität und Elternschaft liegen der Auffassung eines „Drei-Eltern-Kindes“ zugrunde? Im Kontext dieser konzeptuellen Fragen muss eine ethische Analyse des Mitochondrien-Transfers durchgeführt werden. In den meisten Fällen zeigt sich allerdings, dass die ethische Analyse zu stark auf Einzelaspekte fokussiert ist, wodurch diese konzeptuellen Fragen aus dem Blick geraten. Daher verbinden wir in unserem Beitrag die ethische Analyse mit konzeptuellen Überlegungen. Dabei ist es von zentraler Bedeutung, auch die biomedizinischen Grundlagen des Verfahrens eingehend zu erörtern, um die konzeptuellen Aspekte angemessen einordnen zu können. In einem ersten Schritt erläutern wir die unterschiedlichen Verfahren des Mitochondrien-Transfers. In einem zweiten Schritt schlagen wir eine konzeptuelle Klärung der drei genannten Fragen vor. Diese konzeptuelle Klärung dient als Grundlage, um die ethischen Aspekte der reproduktiven Selbstbestimmung, Risikoabwägung sowie Elternschaft und Identitätskonzeption zu analysieren. In einem dritten Schritt fassen wir die Ergebnisse zusammen. (shrink)

BackgroundClustered Regularly Interspaced Short Palindromic Repeats-associated technology may allow for efficient and highly targeted gene editing in single-cell embryos. This possibility brings human germline editing into the focus of ethical and legal debates again.Main bodyAgainst this background, we explore essential ethical and legal questions of interventions into the human germline by means of CRISPR-Cas: How should issues of risk and uncertainty be handled? What responsibilities arise regarding future generations? Under which conditions can germline editing measures be therapeutically legitimized? For this (...) purpose, we refer to a scenario anticipating potential further development in CRISPR-Cas technology implying improved accuracy and exclusion of germline transmission to future generations. We show that, if certain concepts regarding germline editing are clarified, under such conditions a categorical prohibition of one-generation germline editing of single-cell embryos appears not to be ethically or legally justifiable.ConclusionThese findings are important prerequisites for the international debate on the ethical and legal justification of germline interventions in the human embryo as well as for the harmonization of international legal standards.

Several objections against the morality of researching or employing mitochondrial replacement techniques have been advanced recently. In this paper, I examine three of these objections and show that they are found wanting. First I examine whether mitochondrial replacement techniques, research and clinical practice, should not be carried out because of possible harms to egg donors. Next I assess whether mitochondrial replacement techniques should be banned because they could affect the study of genealogical ancestry. Finally, I examine the claim that mitochondrial (...) replacement techniques are not transferring mitochondrial DNA but nuclear DNA, and that this should be prohibited on ethical grounds. (shrink)
