Fetal ultrasonography has made women's and men's relationship to the fetus more equal. Drawing on information obtained from multiple conjoint interviews with 62 childbearing couples, I suggest that although women and men are both advantaged by fetal ultrasonography, expectant fathers' experience of the fetus is always enhanced, whereas pregnant women's experience may also be attenuated. For men, fetal ultrasonography is like a prosthetic device: an enabling mechanism that permits them access to a female world from which they have been excluded (...) because of their limited biological role in reproduction. For women, fetal ultrasonography is enabling, but it may also be a disabling mechanism that disrupts their privileged access to the fetus. (shrink)

Is the mammalian embryo/fetus a part of the organism that gestates it? According to the containment view, the fetus is not a part of, but merely contained within or surrounded by, the gestating organism. According to the parthood view, the fetus is a part of the gestating organism. This paper proceeds in two stages. First, I argue that the containment view is the received view; that it is generally assumed without good reason; and that it needs substantial support if it (...) is to be taken seriously. Second, I argue that the parthood view derives considerable support from a range of biological and physiological considerations. I tentatively conclude in favour of the parthood view, and end by identifying some of the interesting questions it raises. (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)

Mitochondrial DNA (mtDNA) diseases are a group of neuromuscular diseases that often cause suffering and premature death. New mitochondrial replacement techniques (MRTs) may offer women with mtDNA diseases the opportunity to have healthy offspring to whom they are genetically related. MRTs will likely be ready to license for clinical use in the near future and a discussion of the ethics of the clinical introduction ofMRTs is needed. This paper begins by evaluating three concerns about the safety of MRTs for clinical (...) use on humans: (1) Is it ethical to use MRTs if safe alternatives exist? (2) Would persons with three genetic contributors be at risk of suffering? and (3) Can society trust that MRTs will be made available for humans only once adequate safety testing has taken place, and that MRTs will only be licensed for clinical use in a way that minimises risks? It is then argued that the ethics debate about MRTs should be reoriented towards recommendingways to reduce the possible risks of MRT use on humans. Two recommendations are made: (1) licensed clinical access to MRTs should only be granted to prospective parents if they intend to tell their children about their MRT conception by adulthood; and (2) sex selection should be used in conjunction with the clinical use ofMRTs, in order to reduce transgenerational health risks.

This article argues that a particular metaphysical model permeates cultural practices surrounding pregnancy: the foetal container model. Widespread uncritical reliance on this view of pregnancy has been highly detrimental to women's liberty and reproductive autonomy. In this article, I extend existing critiques of the medical treatment of pregnant women to the context of the burgeoning commercial surrogacy industry. In doing so, I aim to show that our philosophical analysis in both spheres is constrained by the presupposition that the foetus and (...) pregnant woman are metaphysically and ethically distinct entities. By exploring the similarities and differences between the expectations placed on pregnant women in these two spheres, I show that the foetal container model is not a homogeneous understanding of pregnancy applied consistently across contexts; rather, it has been used to justify various practices and attitudes toward pregnancy and pregnant women through different moral frameworks, in the service of different overarching aims.

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)

Nowadays, novel techniques such as Reciprocal effortless in vitro fertilization (ReIVF) enable two individuals to “carry the same pregnancy,” that is to “carry” the same embryo in both their bodies. However, even though these techniques are likely to be increasingly requested, little is known about their safety and efficacy, and much less about their bioethical legitimacy and issues. Considering their uniqueness, this study assesses the compatibility of ReIVF as well as of another similar technique with the classical principles of medical (...) ethics: autonomy, beneficence, nonmaleficence, and justice. The aim is twofold: (i) to start investigating whether these techniques and their underlying reasons are, or could ever be, bioethically justifiable and (ii) to make clinicians and any other potentially interested persons such as researchers, lawmakers and prospective parents themselves are more aware of the health and social implications of using these techniques. Hence, after a brief overview of the technical aspects of the procedures that allow two persons to carry the same pregnancy, this study offers a general moral framework that can be useful for starting to address some relevant aspects of these procedures, such as their benefits and harms on the health of the individuals involved, the reasons behind their use, and the possibility that they might be covered by states in the future. Finally, this study provides a bioethical overview on ReIVF as well as on similar techniques considering different perspectives, while also suggesting some questions and recommendations for further research.

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.

Reproductive biotechnologies can separate concepts of parenthood into genetic, gestational and social dimensions, often leading to a fragmentation of heteronormative kinship models and posing a challenge to historical methods of establishing legal and/or moral parenthood. Using fictional cases, this article will demonstrate that the issues surrounding the intersection of current and emerging reproductive biotechnologies with definitions of parenthood are already leading to confusion regarding social and legal family ties for offspring, which is only expected to increase as new technologies develop. (...) Rather than opposing these new technologies to reassert traditional concepts of the family, however, this article will explore the opportunities that these technologies represent for re‐imagining various culturally cherished values of family‐making in a way that is inclusive of diverse genders, sexualities and cultures. It will consider IVF, gametogenesis, mitochondrial donation, surrogacy, artificial gestation, CRISPR‐Cas9 gene editing, foster care and adoption as some of many possible pathways to parenthood, including for members of the LGBTIAUQ+ community.
