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)

In a recent paper – Lesbian motherhood and mitochondrial replacement techniques: reproductive freedom and genetic kinship – we argued that lesbian couples who wish to have children who are genetically related to both of them should be allowed access to mitochondrial replacement techniques. Françoise Baylis wrote a reply to our paper –‘No’ to lesbian motherhood using human nuclear genome transfer– where she challenges our arguments on the use of MRTs by lesbian couples, and on MRTs more generally. In this reply (...) we respond to her claims and further clarify our position. (shrink)

Since mitochondrial replacement techniques were developed and clinically introduced in the United Kingdom, there has been much discussion of whether these lead to children borne of three parents. In the UK, the regulation of MRT has dealt with this by stipulating that egg donors for the purposes of MRT are not genetic parents even though they contribute mitochondrial DNA to offspring. In this paper, I examine the way that the Human Fertilisation and Embryology Act in the UK manages the question (...) of parentage. I argue that the Act breaks the link typically made between genetic causation and genetic parenthood by redefining genetic causation solely in terms of nuclear genetics. Along with this, mtDNA is construed as a kind of supplement to the nuclear family. Drawing on the account of the supplement developed by Jacques Derrida, I argue that mtDNA and the women who donate it are seen as both essential to establishing the nuclear family but also exterior to and insignificant for it.

The UK-based deliberations that led up to the legalisation of two new ‘mitochondrial donation’ techniques in 2015, and which continued after that time as regulatory details were determined, featured a division of advisory labour that is common when decisions are made about new technologies. An expert panel was convened by the Human Fertilisation and Embryology Authority, charged with assessing the scientific and technical aspects of these techniques. Meanwhile, the Nuffield Council on Bioethics addressed the ethical issues. While this division of (...) labour was undertaken in the name of thoroughness, I argue here that it can have the unintended consequence that hybrid questions that simultaneously involve ethical and technical aspects—especially questions about where to set evidential thresholds for the acceptance of new technology—do not receive enough attention.

UK law permits parents to use mitochondrial replacement to have genetically-related children without serious mitochondrial disease. However, long-term follow-up is required for each case. Whet...

Tri-parent baby technology is an assisted reproductive treatment which aims to minimize or eliminate maternal inheritance of mutated mitochondrial DNA. The technology became popular following the move by the United Kingdom in granting license to a group of researchers from the Newcastle Fertility Centre, Newcastle University to conduct research on the symptoms of defective mtDNA. This technology differs from other assisted reproductive technology because it involves the use of gamete components retrieved from three different individuals. Indirectly, it affects the preservation (...) of lineage which is important from an Islamic point of view. This paper aims to analyze and discuss the implications of the tri-parent technology on preservation of lineage from the perspective of Maqasid al-Shari’ah based the Islamic bioethics. The analysis shows that there are a few violations of the preservation of lineage, hence the tri-parent baby technology should not be permitted. (shrink)
