In this article, I challenge the widespread presumption that a child should have exactly two parents. I consider the pros and cons of various numbers of parents for the people most directly affected – the children themselves and their parents. The number of parents, as well as the ratio of parents to children, may have an impact on what resources are available, what relationships can develop between parents and children, what level of conflict can be expected in the family, as (...) well as the costs involved in parenting and the experience of parenting a child. Indirectly, there is also an effect on who will have the opportunity to be a parent, as well as on wider social issues that I mention but do not discuss. Having considered all these factors, I conclude that there is some reason to believe that three or more parents is usually better than one or two, especially if children are to have siblings, which is typically beneficial. However, these reasons are not strong enough to support a general presumption in favor of any particular number. We should therefore jettison the two‐parent presumption and make different numbers of parents more socially accepted as well as legally possible. (shrink)

Some philosophers argue that we should limit procreation – for instance, to one child per person or one child per couple – in order to reduce our aggregate carbon footprint. I provide additional support to the claim that population size is a matter of justice, by explaining that we have a duty of justice towards the current generation of children to pass on to them a sustainable population. But instead of, or, more likely, alongside with, having fewer children in in (...) each family, we could also create families with more than two parents. I explore this possibility by pointing out the ways in which multi-parenting can advance children’s interests: in higher levels of well-being, in non-monopolistic child-rearing, and in a future opportunity to become themselves parents.

Ought parents, in general, to value being biologically tied to their children? Is it important, in particular, that both parents be biologically tied to their children? I will address these fundamental questions by looking at a fairly new practice within IVF treatments, so-called IVF-with-ROPA ( Reception of Oocytes from Partner ), which allows lesbian couples to „share motherhood‟ with one partner providing the eggs while the other becomes pregnant. I believe that IVF-with-ROPA is, just like other IVF treatments, morally permissible; (...) but here I argue that the increased biological ties which IVF-with-ROPA allows for do not have any particular value beside the satisfaction of a legitimate wish, because there is no intrinsic value in a biological tie between parents and children; further, I argue that equality within parental projects cannot be achieved by redistributing biological ties.

In this paper, we will discuss the prospect of human reproduction achieved with gametes originating from only one person. According to statements by a minority of scientists working on the generation of gametes in vitro, it may become possible to create eggs from men’s non-reproductive cells and sperm from women’s. This would enable, at least in principle, the creation of an embryo from cells obtained from only one individual: ‘solo reproduction’. We will consider what might motivate people to reproduce in (...) this way, and the implications that solo reproduction might have for ethics and policy. We suggest that such an innovation is unlikely to revolutionise reproduction and parenting. Indeed, in some respects it is less revolutionary than in vitro fertilisation as a whole. Furthermore, we show that solo reproduction with in vitro created gametes is not necessarily any more ethically problematic than gamete donation—and probably less so. Where appropriate, we draw parallels with the debate surrounding reproductive cloning. We note that solo reproduction may serve to perpetuate reductive geneticised accounts of reproduction, and that this may indeed be ethically questionable. However, in this it is not unique among other technologies of assisted reproduction, many of which focus on genetic transmission. It is for this reason that a ban on solo reproduction might be inconsistent with continuing to permit other kinds of reproduction that also bear the potential to strengthen attachment to a geneticised account of reproduction. Our claim is that there are at least as good reasons to pursue research towards enabling solo reproduction, and eventually to introduce solo reproduction as an option for fertility treatment, as there are to do so for other infertility related purposes.

In a host surrogate motherhood arrangement, the surrogate agrees to be implanted with, and carry to term, an embryo created from the commissioning couple9s gametes. When the surrogate child is born, it is the surrogate mother who, according to UK law, holds the legal status of mother. By contrast, the commissioning mother possesses no maternal status and she can only attain it once the surrogate agrees to the completion of the arrangement. One consequence of this is that, in the event (...) that a host arrangement fails, the commissioning mother is left without maternal status. In this paper, I argue that this denial of maternal status misrepresents the commissioning mother9s role in the host arrangement and her relationship with the surrogate child. Consequently, I suggest that commissioning mothers participating in host surrogacy arrangements ought to be granted the status of mother in the event that the arrangement fails. (shrink)
