A number of advances in assisted reproduction have been greeted by the accusation that they would produce children ‘without parents’. In this paper I will argue that while to date these accusations have been false, there is a limited but important sense in which they would be true of children born of a reproductive technology that is now on the horizon. If our genetic parents are those individuals from whom we have inherited 50% of our genes, then, unlike in any (...) other reproductive scenario, children who were conceived from gametes derived from stem cell lines derived from discarded IVF embryos would have no genetic parents! This paper defends this claim and investigates its ethical implications. I argue that there are reasons to think that the creation of such embryos might be morally superior to the existing alternatives in an important set of circumstances. (shrink)

In this paper I examine what I take to be the best case for reproductive human cloning, as a medical procedure designed to overcome infertility, and argue that it founders on an irresolvable tension in the attitude towards the importance of being ‘genetically related’ to our children implied in the desire to clone. Except in the case where couples are cloning a child they have previously conceived naturally, cloning is unable to establish the right sort of genetic relation to make (...) couples the parents of their cloned child. If anybody is the genetic parent of a cloned child it is the natural parent(s) of the DNA donor. Paradoxically, in order to resist the claims of the parents of the donor to the cloned child, the argument for human reproductive cloning must place more weight on the intention to parent a child, than we do in cases of ordinary reproduction. It must insist that the parental relation is established by the intentions of the couple who bring a clone into the world and not by their genetic relation to the child. The emphasis placed on intention as establishing the parental relationship works to undermine the justification for cloning in the first place. For cloning to play a useful role as a reproductive technology, it must allow couples to become parents who could do so no other way. However, to the extent that intention is sufficient to establish parenthood, adoption or surrogacy, which are existing alternatives to cloning, will serve equally well to allow couples to become parents.

ABSTRACTHow should we conceive of a right to reproduce? And, morally speaking, what might be said to justify such a right? These are just two questions of interest that are raised by the technologies of assisted reproduction. This paper analyses the possible legitimate grounds for a right to reproduce within the two main theories of rights; interest theory and choice theory.

The recent success in generating live offspring from embryonic stem cell –derived gametes in mice sparked visions of growing tailor-made sperm for men faced with infertility. However, although this development will almost certainly lead to new insights into the processes underlying spermatogenesis and thus in the possible causes of male infertility, it is less certain if deriving sperm from ES cells, which are in turn derived from a sterile man, can make someone a genetic parent. As the gap between newly (...) envisioned reproductive technologies and natural reproduction widens, the question thus needs to be asked if these possible therapies still lead to genetic parenthood.

The main objection to human embryonic stem cell research is that it involves killing human embryos, which are essentially beings of the same sort that you and I are. This objection presupposes that we once existed as early embryos and that we had the same moral status then that we have now. This essay challenges both those presuppositions, but focuses primarily on the first. I argue first that these presuppositions are incompatible with widely accepted beliefs about both assisted conception and (...) monozygotic twinning. I then argue that we never existed as embryos. If this last claim is right, killing an embryo does not kill someone like you or me but merely prevents one of us from existing. (shrink)

Human development is a matter of complex interactions between nutritional regimes, genes, educational regimes and other diverse developmental resources. I argue that there is no ethically salient difference between the contributions made to development by genes and the contributions made by these other resources. Since we think nutrition and schooling should be included in the calculus of distributive justice, we should include at least some genes in this calculus too. What is more, under the right circumstances genetic engineering may become (...) a useful tool for the distribution of developmental resources. This said, attention to the parity of genetic and environmental causation can also help to articulate the legitimate suspicions many groups have of genetic engineering. (shrink)

What exactly is it that makes someone a parent? Many people hold that parenthood is grounded, in the first instance, in the natural derivation of one person's genetic constitution from the genetic constitutions of others. We refer to this view as "Geneticism". In Part I we distinguish three forms of geneticism on the basis of whether they hold that direct genetic derivation is sufficient, necessary, or both sufficient and necessary, for parenthood. Parts two through four examine three arguments for geneticism: (...) the property argument, the causal argument, and the parity argument. We conclude that none of these arguments succeeds. (shrink)

Because an influenza pandemic would create the most serious hardships for those who already face most serious hardships, countries should take special measures to mitigate the effect of a pandemic on existing social inequalities. Unfortunately, there is little evidence that anybody is thinking about that.

Robert Sparrow has recently raised the possibility that stem cell technology could in the future be used to create multiple generations of embryos in the laboratory before transferring one embryo to a woman’s womb to create a pregnancy. Sparrow argues that any children produced in this way would be genetic orphans—they would lack living genetic parents—and explores the possible moral implications of this. A number of other authors have raised objections to Sparrow’s moral claims, but his descriptive claim remains unchallenged. (...) In this chapter, we challenge it, arguing that Sparrow’s imagined technology could be performed in such a way that the children produced would have living genetic parents. (shrink)

Ovarian tissue transplantation is an experimental procedure that can be used to treat both infertility and premature menopause. Working within the current legal framework in the USA, I examine whether ovarian tissue should be legally treated like gametes or organs in the case of ovarian tissue transplantation between two women. One option is to base classification upon its intended use: ovarian tissue used to treat infertility would be classified like gametes, and ovarian tissue used to treat premature menopause would be (...) classified like organs. In the end, however, I argue that this approach will not work because it engenders too many legal, cultural and logistical concerns and that, at least for the near future, we should treat ovarian tissue like gametes.

Infertility affects 15 per cent of the world's couples. Research at Edinburgh University has been directed at transplanting fetal ovarian tissue into infertile women, thus enabling them to bear children. Fetal ovary transplantation (FOT) has generated substantial controversy; in fact, one ethicist deemed the procedure 'so grotesque as to be unbelievable' (1). Some have suggested that fetal eggs may harbour unknown chromosomal abnormalities: however, there is no evidence that these eggs possess a higher incidence of genetic anomaly than ova found (...) in a healthy adult female. There is also concern that fetal egg children will be psychologically harmed by the knowledge of their special conceptual status. It will be demonstrated that special conceptual status in and of itself does not determine developmental success. Rather, psychological well-being is dependent upon how the family and child cope with the unique challenges inherent in FOT. Lastly, though considering FOT a legitimate method of family building, given the global population crisis the wisdom of procreational rights will be challenged. Inherent to this challenge is a re-evaluation of the treatment of infertility as a significant disease necessitating remedy. (shrink)

What is it that makes someone a parent? Many writers – call them ‘monists’– claim that parenthood is grounded solely in one essential feature that is both necessary and sufficient for someone's being a parent. We reject not only monism but also ‘necessity’ views, in which some specific feature is necessary but not also sufficient for parenthood. Our argument supports what we call ‘pluralism’, the view that any one of several kinds of relationship is sufficient for parenthood. We begin by (...) challenging monistic versions of gestationalism, the view that gestation uniquely grounds parenthood. Monistic and necessity gestationalism are implausible. First, we raise the ‘paternity problem’– necessity gestationalists lack an adequate account of how men become fathers. Second, the positive arguments that necessity gestationalists give are not compelling. However, although gestation may not be a necessary condition for parenthood, there is good reason to think that it is sufficient. After further rebutting an ‘intentionalist’ account of parenthood, in which having and acting on intentions to procreate and rear is necessary for parenthood, we end by sketching a pluralist picture of the nature of parenthood, rooted in causation, on which gestation, direct genetic derivation, extended custody, and even, sometimes, intentions, may be individually sufficient for parenthood.

This paper explores the implications of human reproductive cloning for our notions of parenthood. Cloning comes in numerous varieties, depending on the kind of cell to be cloned, the age of the source at the time the clone is created, the intended social relationship, if any, between source and clone, and whether the clone is to be one of one, or one of many, genetically identical individuals alive at a time. The moral and legal character of an act of cloning (...) may, moreover, differ in light of these distinctions. Surprisingly, however, reproductive cloning in all its variety seems to undermine the view of parenthood that is most popular among proponents of reproductive technology in the bioethics literature. This view, geneticism, has much to recommend it. I will show, however, that as commonly understood, geneticism is incompatible with the reproductive view of cloning. I then canvass alternative accounts of parenthood—namely, conventionalism, gestationalism, and intentionalism—but none succeeds in explaining reproductive cloning. I thus return to a reconstructed version of geneticism. I argue that the problem for geneticism rests not with the notion of genetic parenthood as such but with a particular, flawed, understanding of it, which I call informational geneticism. Informational geneticism should be rejected in favor of a “physicalistic” version of geneticism, which treats genes as particular objects, not abstract types, and takes seriously the essentially embodied character of reproduction. For these reasons, physicalistic geneticism survives the challenge represented by reproductive cloning. Additionally, physicalistic geneticism accommodates attractive aspects of competing views of parenthood, meeting some powerful objections in the process. (shrink)
