A clinical trial on mitochondrial replacement therapy is currently being conducted and if this technique proves effective, National Health Service England will fund MRT through the highly specialised services funding stream. This paper considers whether MRT should be publicly funded by the NHS. Given the current financial pressure the NHS is experiencing, a comprehensive discussion is essential. There is yet to be a thorough discussion on MRT funding, perhaps because this is a small-scale issue and presumed to be covered by (...) the HSS budget. However, the source of funding has not been confirmed due to the trial’s incompletion. Upon its completion, reasoned decisions need to be made over the allocation of scarce NHS resources. It is therefore important to consider the following arguments in advance. Three arguments given against NHS funding of MRT will be evaluated. The first argument against NHS funding examines the HSS overspending its budget in an underfunded NHS, suggesting funding must be carefully reprioritised. Second, the ethical issue of allowing public access to a technique with insufficient evidence behind it will be explored. The final point considers the option of privately funding MRT and how this would affect the treatment’s development. After illustrating the weaknesses of such arguments, it will be concluded that MRT should be funded by the NHS. (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)

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)

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.
