Few discussions of the ethics of mitochondrial ‘replacement’ techniques have drawn significant ethical distinctions between the two approaches now legal in the U.K. However, Anthony Wrigley, Stephen Wilkinson and John Appleby have together argued that under some circumstances pronuclear transfer (PNT) may be in better ethical standing than maternal spindle transfer (MST). They base their conclusion on what they allege to be different implications of the techniques with respect to non‐identity considerations, which they ground on a version of origin (...) essentialism. I raise a series of problems for their argument, which have cautionary implications for invocations of origin essentialism that go beyond specialized debates regarding MST and PNT. I argue that (i) origin essentialism is a fragile foundation for non‐identity considerations; (ii) gametic essentialism, which Wrigley et al. believe licenses their claims, is more questionable than origin essentialism; (iii) gametic essentialism does not straightforwardly justify their conclusion; and (iv) their conclusion in fact relies on an especially dubious position that we can call chromosomal origin essentialism. No good reasons have yet been supplied to distinguish PNT from MST on ethical grounds, and one should be wary of basing claims with practical impact on fragile foundations relating to origin essentialism.

Mitochondrial replacement therapy (MRT), also called nuclear genome transfer and mitochondrial donation, is a new technique that can be used to prevent the transmission of mitochondrial DNA diseases. Apart from the United Kingdom, the first country to approve MRT in 2015, Australia became the second country with a clear regulatory path for the clinical applications of this technique in 2021. The rapidly evolving clinical landscape of MRT makes the elaboration and evaluation of the responsible use of this technology (...) a pressing matter. As jurisdictions with less strict or non-existent reproductive laws are continuing to use MRT in the clinical context, the need to address the underlying ethical issues surrounding MRT’s clinical translation is fundamental.

Florence Ashley has argued that requiring patients with gender dysphoria to undergo an assessment and referral from a mental health professional before undergoing hormone replacement therapy is unethical and may represent an unconscious hostility towards transgender people. We respond, first, by showing that Ashley has conflated the self-reporting of symptoms with self-diagnosis, and that this is not consistent with the standard model of informed consent to medical treatment. Second, we note that the model of informed consent involved in (...) cosmetic surgery resembles the model Ashley defends, and that psychological assessment and referral is recognised as an important aspect of such a model. Third, we suggest that the increased prevalence of psychiatric morbidity in the transgender population arguably supports the requirement of assessment and referral from a mental health professional prior to undergoing HRT.

Mitochondrial replacement technology (MRT) is an emerging and complex bioethical issue. This treatment aims to eliminate maternal inherited mitochondrial DNA (mtDNA) disorders. For Muslims, its introduction affects every aspect of human life, especially the five essential interests of human beings—namely, religion, life, lineage, intellect, and property. Thus, this technology must be assessed using a comprehensive and holistic approach addressing these human essential interests. Consequently, this article analyses and assesses tri-parent baby technology from the perspective of Maqasidic bioethics—that is, Islamic (...) bioethics based on the framework of Maqasid al-Shariah. Using this analysis, this article suggests that tri-parent baby technology should not be permitted for Muslims due to the existence of third-party cell gametes which lead to lineage mixing and due to the uncertain safety of the therapy itself and because the major aim of the technology is to fulfil the affected couples interest to conceive their own genetically healthy child, not to treat and cure mtDNA disorders sufferers.

Although informed consent models for prescribing hormone replacement therapy are becoming increasingly prevalent, many physicians continue to require an assessment and referral letter from a mental health professional prior to prescription. Drawing on personal and communal experience, the author argues that assessment and referral requirements are dehumanising and unethical, foregrounding the ways in which these requirements evidence a mistrust of trans people, suppress the diversity of their experiences and sustain an unjustified double standard in contrast to other forms (...) of clinical care. Physicians should abandon this unethical requirement in favour of an informed consent approach to transgender care. (shrink)

Gene replacement therapy holds great promise in the treatment of many genetic CNS disorders. This commentary discusses the feasibility of gene replacement therapy in the unique context of the retina, with regard to: (1) the genetics of retinal neoplasia and degeneration, (2) available gene transfer technology, and (3) potential gene delivery vehicles.

For focal neurodegenerative diseases or brain tumors, localized delivery of protein or genetic vectors may be sufficient to alleviate symptoms, halt disease progression, or even cure the disease. One may circumvent the limitation imposed by the blood-brain barrier by transplantation of genetically altered cell grafts or focal inoculation of virus or protein. However, permanent gene replacement therapy for diseases affecting the entire brain will require global delivery of genetic vectors. The neurotoxicity of currently available viral vectors and the (...) transient nature of transgene expression invivomust be overcome before their use in human gene therapy becomes clinically applicable.

Mitochondria, the powerhouses of our cells, are essential to life. Normal mitochondrial function is achieved through the cooperative interaction of the nuclear and mitochondrial genomes. New IVF approaches intended to circumvent devastating mitochondrial disease look set to change the ancient pattern of mtDNA inheritance and interaction with unknown consequences.

This article argues that two forms of mitochondrial replacement therapy, maternal spindle transfer and pro-nuclear transfer, are not therapies at all because they do not treat children who are coming into existence. Rather, these technologies merely create healthy children where none was inevitable. Even if creating healthy lives has some value, it is not to be confused with the medical value of a cure or therapy. The article addresses a recent Bioethics article, ‘Mitochondrial Replacement: Ethics and (...) Identity,’ by Wrigley, Wilkinson, and Appleby, who argue that PNT is morally favorable to MST due to the Non-Identity Problem. Wrigley et al. claim that PNT, since it occurs post-conception, preserves the identity of the resulting child, whereas MST, since it occurs pre-conception, is an identity-altering technique. As such, a child born with mitochondrial disease could complain that her parents failed to use PNT, but not MST. The present article argues that the authors are mistaken: both MST and PNT are identity-affecting techniques. But this is of little matter, for we should be cautious in drawing any moral conclusions from the application of the Non-Identity Problem to cases. The article then argues that the authors are mistaken in inferring that PNT is a type of embryonic cure or therapy for children with mitochondrial disease. The article cautions against the mistaken life-saving rhetoric that is common in bioethics discussions of MRTs. (shrink)

In a previous article, I argued that assessment requirements for transgender hormone replacement therapy are unethical and dehumanising. A recent response published by the Journal of Medical Ethics criticises this proposal. In this reply, I advance that their response misunderstood core parts of my argument and fails to provide independent support for assessment requirements. Though transition-related care may have similarities with cosmetic surgeries, this does not suffice to establish a need for assessments, and nor do the high rates (...) of depression and anxiety justify assessments, especially given the protective role HRT plays towards mental well-being.

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 critically examines the volitional normative model of disease and its underlying nanotechnologic vision of medicine both defended by Robert Freitas. Having provided an account of this vision, we explicate the highlight of the model, which is a concept of disease based on individual values and preferences. The model’s normative positions are then critiqued based on our argument that the epistemic basis of Freitas’s vision of nanotechnologic medicine and, by extension, of his volitional normative model of disease is scientifically (...) flawed. An ethical and social critique of the model is then conducted on the basis of the model’s implicit ethical underpinnings. We argue that Freitas fails to justify the normativity of his model by not addressing the ethical issues that permeate it, one of which is the question of responsibility regarding the development of medical nanotechnology and the practice of new forms of medicine such as the one he envisions. We conclude that, due to its radically individualistic position, the model implies an unjustified view of nanoethics and relegates this field of ethics to the periphery of discussions of nanomedicine.

Parkinson's disease patients receiving dopaminergic treatment may experience bursts of creativity. Although this phenomenon is sometimes recognized among patients and their clinicians, the association between dopamine replacement therapy in PD patients and creativity remains underexplored. It is unclear, for instance, whether DRT affects creativity through convergent or divergent thinking, idea generation, or a general lack of inhibition. It is also unclear whether DRT only augments pre-existing creative attributes or generates creativity de novo. Here, we tested a group of (...) PD patients when “on” and “off” dopaminergic treatment on a series of tests of creative problem-solving, and related their performance to a group of matched healthy controls as well as to their pre-PD creative skills and measures of inhibition/impulsivity. Results did not provide strong evidence that DRT improved creative thinking in PD patients. Rather, PD patients “on” medication showed less flexibility in divergent thinking, generated fewer ideas via insight, and showed worse performance in convergent thinking overall than healthy controls. Pre-PD creative skills predicted enhanced flexibility and fluency in divergent thinking when PD patients were “on” medication. However, results on convergent thinking were mixed. Finally, PD patients who exhibited deficits in a measure of inhibitory control showed weaker convergent thinking while “on” medication, supporting previous evidence on the importance of inhibitory control in creative problem-solving. Altogether, results do not support the hypothesis that DRT promotes creative thinking in PD. We speculate that bursts of artistic production in PD are perhaps conflated with creativity due to lay conceptions of creativity. (shrink)

Mitochondrial replacement therapy (MRT) utilises nuclear transfer technology to replace defective mitochondria with healthy ones and thereby minimise the risk of a mitochondrial disease passing from a mother to her child. It promises much but comes with ethical controversy, significant risk of harm and many unknowns. Forming a position on MRT requires accurate information about the current state of knowledge, and an appreciation of the ethical issues at stake. Ethical deliberations will vary depending on the framework used. There (...) are in principle objections to MRT on the grounds of direct harm to human embryos and germline genetic modification. But even without these objections MRT can be weighed in terms of the balance between risks and benefits, alternatives and uncertainties. This paper explores the evidence and lays out the relevant issues to assist such a deliberation. (shrink)

The use of aggregated quality of life estimatesin the formation of public policy and practiceguidelines raises concerns about the moralrelevance of variability in values inpreferences for health care. This variabilitymay reflect unique and deeply held beliefs thatmay be lost when averaged with the preferencesof other individuals. Feminist moral theorieswhich argue for attention to context andparticularity underline the importance ofascertaining the extent to which differences inpreferences for health states revealinformation which is morally relevant toclinicians and policymakers. To facilitatethese considerations, we present (...) an empiricalstudy of preferences for the timing andoccurrence of health states associated withhormone replacement therapy (HRT). Sixteenwomen between the ages of 45 and 55 wereenrolled in this pilot study. Theirpreferences regarding five health statesassociated with HRT (menopausal symptoms, sideeffects of HRT, breast cancer, myocardialinfarction, and osteoporosis) were assessed inquantitative terms known as utilities. Twostandard methods, the visual analog scale (VAS) and the standard gamble (SG), were used toassess utility and time preference (calculatedas a discount rate). The wide variability ofresponses underlines the importance oftailoring health care to individual women'spreferences. Policy guidelines whichincorporate utility analysis must recognize thenormative limitations of aggregatedpreferences, and the moral relevance ofindividual conceptions of health. (shrink)

This article examines and presents examples of contemporary advertising within the medical and health professions that continue the process and organisation of knowledge about women and their reproductive bodies. It draws on feminist and poststructural perspectives to inform a critical evaluation of the visual representations of menopausal women and hormone replacement therapy. These representations work to construct certain definitions of the feminine that sustain and support existing contradictory cultural meanings and values about menopause. I argue that the images (...) continue to misrepresent and define what forms of femininity and sexual gender are desirable and acceptable for menopausal women. The article addresses the problems of gender discrimination and bias within the advertising industry, and illustrates the ways in which readers of visual texts may be influenced by stereotypic assumptions concerning a woman's lived experience of menopause. It illustrates how specific symbolic images directed towards men and women for hormone replacement therapy, testosterone deficiency and sexual dysfunction influence the viewer's decision making and action responses.

Advances in medicine in the latter half of the twentieth century have dramatically altered human bodies, expanding choices around what we do with them and how they connect to other bodies. Nowhere is this more so than in the area of reproductive technologies. Reproductive medicine and the laws surrounding it in the UK have reconfigured traditional boundaries surrounding parenthood and the family. Yet culture and regulation surrounding RTs have combined to try to ensure that while traditional boundaries may be pushed, (...) they are reconstructed in similar ways. This paper looks at the most recent RT to be permitted in the UK, mitochondria replacement therapy. Despite controversial media headlines surrounding the technique, MRT is in fact an example of how science and regulation seek to expand models of traditional relatedness in a way that doesn’t challenge the existing order. Yet, like other RTs, while attempts are made to ensure it doesn’t push traditional boundaries too far, fissures and inconsistencies appear in law and culture, which give interesting insights into how genetics, parentage and identity are being mediated in new but familiar ways.

Rereading Renée C. Fox's “A Sociological Perspective on Organ Transplantation and Hemodialysis,” published in 1970, one is likely to be struck more by continuity than by change. The most pressing of the social, policy, and ethical concerns that Fox raised remain problematic fifty years later. We still struggle with scientific and clinical uncertainty, with the boundary between experimentation and therapy, and with the cost of organ replacement therapies and disparities in how they are allocated. We still have an (...) imperfect understanding of transplant immune responses. We still debate when a potential donor “actually” dies, and we still seem to think better empirical criteria could harmonize the diverse religious, cultural, and socioeconomic values of patients, providers, third‐party payers, and policy‐makers. Organ transplantation was for Fox both a particular case unfolding in time and an entryway for discussing the difficult moral questions presented by many new medical technologies in a context of high demand and limited resources.

Until recently, the problem of traumatic brain injury in sports and the problem of performance enhancement via hormone replacement have not been seen as related issues. However, recent evidence suggests that these two problems may actually interact in complex and previously underappreciated ways. A body of recent research has shown that traumatic brain injuries, at all ranges of severity, have a negative effect upon pituitary function, which results in diminished levels of several endogenous hormones, such as growth hormone and (...) gonadotropin. This is a cause for concern for many popular sports that have high rates of concussion, a mild form of TBI. Emerging research suggests that hormone replacement therapy is an effective treatment for TBI-related hormone deficiency. However, many athletic organizations ban or severely limit the use of hormone replacing substances because many athletes seek to use them solely for the purposes of performance enhancement. Nevertheless, in the light of the research linking traumatic brain injury to hypopituitarism, this paper argues that athletic organizations’ policies and attitudes towards hormone replacement therapy should change. We defend two claims. First, because of the connection between TBI and pituitary function, it is likely many more athletes than previously acknowledged suffer from hormone deficiency and thus could benefit from hormone replacement therapy. Second, athletes’ hormone levels should be tested more rigorously and frequently with an emphasis on monitoring TBI and TBI-related issues, rather than simply monitoring policy violations. (shrink)

Florence Ashley has responded to our response to ‘Gatekeeping hormone replacement therapy for transgender patients is dehumanising.’ Ashley criticises some of our objections to their view that patients seeking hormone replacement therapy (HRT) for gender dysphoria should not have to undergo a prior psychological assessment. Here we clarify our objections, most importantly that concerning the parity between cosmetic surgery and the sort of intervention Ashley has in mind. Firstly, we show Ashley’s criticism of our comparison is (...) insubstantial. We then examine their comments regarding the analogy between abortion and HRT, and the language of informed consent. We also scrutinize the data upon which Ashley relies to defend the claim that informed consent without assessment always yields positive outcomes, finding this conclusion to be overstated. Finally, even if Ashley’s arguments were vindicated, the claim that the gatekeeping of HRT is motivated by hostility towards transgender people remains unsupported. (shrink)

Many clinicians are experiencing consumer resistance to the prescription of equine HRT (that is hormone replacement therapy which has been manufactured from mare's urine). In this paper I consider the ethical implications of prescribing these preparations. I decide that patients should have a right to refuse such treatment but also ask whether a prescribing doctor should choose one preparation over another on moral grounds. I determine that there is prima facie evidence to suggest that mares may suffer and (...) that prescription of equine HRT (instead of synthetic oestrogen-oestriol) would therefore have to be justified in terms of either offering greater benefits to the women or offering greater value for money to the health service. I find that there is no substantial evidence to suggest that equine HRT offers unique advantages over and above oestriol. I conclude that it would be preferable for a doctor to recommend the synthetic oestrogen to women who want relief from the symptoms of the menopause and protection from osteoporosis and cardiovascular disease.

In this article, an ethical analysis of an educational programme on renal replacement therapy options for patients and their social network is presented. The two main spearheads of this approach are: (1) offering an educational programme on all renal replacement therapy options ahead of treatment requirement and (2) a home-based approach involving the family and friends of the patient. Arguments are offered for the ethical justification of this approach by considering the viewpoint of the various stakeholders (...) involved. Finally, reflecting on these ethical considerations, essential conditions for carrying out such a programme are outlined. The goal is to develop an ethically justified and responsible educational programme. (shrink)

On September 27, 2016 people across the world looked down at their buzzing phones to see the AP Alert: “Baby born with DNA from 3 people, first from new technique.” It was an announcement met with confusion by many, but one that polarized the scientific community almost instantly. Some celebrated the birth as an advancement that could help women with a family history of mitochondrial diseases prevent the transmission of the disease to future generations; others held it unethical, citing medical (...) tourism and consequences for the future of the therapy. The child in question was actually born a few months earlier on April 6, 2016, but the research was published a few months later in the October edition of Fertility and Sterility. The mother carries DNA that could have given the baby Leigh Syndrome, a severe neurological disorder characterized by psychomotor regression that typically results in death between ages two and three.[1] Also known as subacute necrotizing encephalomyelopathy, Leigh Syndrome is caused by genetic mutations in mitochondrial DNA, which causes defective oxidative phosphorylation. Because people with this condition cannot re-form ATP, “demyleniation, gliosis, necrosis, spongiosis, or capillary proliferation”[2] can occur, thereby producing bilateral lesions across the central nervous system. The 36-year-old mother previously had four miscarriages and successfully birthed two children, both of whom survived less than six years due to the syndrome. For religious reasons, the mother opted for Spindle Nuclear Transfer instead of Pronuclear Transfer,[3] which many religious organizations oppose because it entails the destruction of fertilized eggs.[4] In Pronuclear Transfer, both the parent and donor egg are fertilized. The parent’s nuclear material is then removed from the egg containing mutated mitochondria and inserted into the fertilized donor egg—from which the original nuclear material has been removed and destroyed. Spindle Nuclear Transfer, on the other hand, removes the mother’s nuclear material from the egg with unhealthy mitochondria, then implants it into a donor’s egg. The newly created egg is then fertilized with the father’s sperm. This Spindle Nuclear Transfer was performed in Mexico by a team of doctors led by Dr. John Zhang, the founder of the New Hope Fertility Center in New York City. In their report, the doctors outline that five oocytes were successfully reconstituted, four of which developed into blastocysts. Only one was euploid: containing 46 XY chromosomes. Researchers then biopsied that blastocyst and found that the transmission rate of maternal mtDNA was, “5.10 ± 1.11% and the heteroplasmy level for 8993T>G was 5.73%.”[5] This indicates that at the blastocyst stage, around five percent of the mitochondria are from the original maternal egg with the mutation for Leigh Syndrome. After birth, they biopsied different tissues and found that they had an average of less than 1.60 ± 0.92% of transmitted mtDNA from the original maternal egg. The baby is reportedly doing well and the team of doctors concluded that “[h]uman oocytes reconstituted by SNT are capable of producing a healthy live birth. SNT may provide a novel treatment option in minimizing pathogenic mtDNA transmission from mothers to their babies."[6] Even when considered theoretically, Spindle Nuclear Transfer is controversial. Many doctors believe that the risks at this stage of research are too great. Dr. Trevor Stammers, a bioethicist at St. Mary’s University in London, points out: “We do not yet have a clear picture of the interaction between nuclear DNA and mitochondria.”[7] Others hold that faulty mitochondrial DNA can still be transferred during the procedure. Still more argue this technology could create problems because of germline modification.[8] Dr. Paul Knoepfler, a cell biologist at the UC Davis School of Medicine, explains: “Since this is uncharted territory and the children born from this technology would have heritable genetic changes, there are also significant unknown risks to future generations.”[9] However, proponents counter these arguments. They say the benefits outweigh the risks, as “mitochondrial replacement techniques [like Spindle Nuclear Transfer] would eliminate maternal transmission of mitochondrial disease… allowing a woman with a family history of mitochondrial diseases to ensure her children would not be affected.”[10] Additionally, experts say that no symptoms will occur if less than 20% of the transferred mitochondrial DNA is faulty.[11] And while opponents see potential germline modification as a problem, advocates answer that this could stop a family history of mitochondrial disease, which they deem a more serious concern. In this case specifically, however, there are more issues at hand. While the team of doctors did eliminate the possibility of germline modification by selecting a male embryo, there are other ethical concerns. Some argue that this case could be described as “medical tourism.” While New Hope Medical Clinic does maintain a branch in Mexico, Dr. Zhang stated that Mexico has “no rules.”[12] It is a country with underdeveloped regulations, making it difficult to confirm that doctors adhere to widely-held medical and ethical standards. Furthermore, while it is highly unlikely that the child will develop Leigh’s Syndrome, Dr. Dietrich Egli of the New York Stem Cell Foundation says the 5% mitochondrial transfer rate indicates that the technique “was not carried out well.”[13] He points to studies of embryos where the rate of mtDNA transfer was almost ten times lower. Spindle Nuclear Transfer is currently legal in the UK,[14] and many are hoping to see it legalized in the US, although Congress currently prohibits the FDA from considering applications that would entail trials in people.[15] While Dr. Zhang’s work is arguably revolutionary, many wonder if the manner in which this study was performed—in Mexico and with a high mitochondrial transfer rate—will impact the technology’s future in the US. Last week, Dr. Zhang presented the report to scientists gathered in Salt Lake City, saying that while science isn’t a race, it is “in a sense, a race for the family to find a cure, to find hope.”[16] Only time will tell if this study set back other families racing and hoping for a cure.

A Foucauldian discourse analysis is employed to identify how our current understandings of menopause are culturally and historically determined by medical discourse. The polarity of the normal and the abnormal (pathological) became the crux of medical deliberation, where deviation from norms becomes the reason for intervention. Through manifold relations of power and the ‘struggle of knowledges’ medicine derives social authority, influencing social orthodoxies thus normalising menopausal women via discursive constructs. The course of nature in ageing women has been re‐categorised as (...) unnatural. In using the case of hormone therapy (HT) and the emergence of bio‐identical or natural hormones, while deconstructing the premises used in marketing both types of hormone therapy, the tenuousness of scientific claims about these hormones is revealed. Discourses on bio‐identical hormones (BHT) display a reliance on seemingly opposing naturalist and scientific arguments. Menopause, having been constructed as a deficiency disease, required initially chemical hormone replacement and now bio‐identical hormones replacing the mainstream medical solution. The idea of the postmenopausal state as diseased is perpetuated as the basis to suggest therapies to women. This paper suggests that although therapeutic in a few cases, hormone preparations are in fact potentially dangerous lifestyle drugs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Invisible HarmKimberly ZieselmanI’m a 48–year–old intersex woman born with Androgen Insensitivity Syndrome (AIS) writing to share my personal experience as a patient affected by a Difference of Sex Development (DSD). Although I appear to be a DSD patient “success story”, in fact, I have suffered and am unsatisfied with the way I was treated as a young patient in the 1980’s, and the continued lack of appropriate care for (...) intersex people even today.As the Executive Director of the advocacy organization Advocates for Informed Choice and a board member of the AIS–DSD Support Group since 2012, I have heard doctors reference the “silent happy majority” of DSD patients all too often. They speak [End Page 122] of patients who were treated in childhood and went on to live (seemingly) contented lives. It appears however that doctors have drawn this conclusion from the fact that most of their patients have not returned to complain about their treatment. While there is little evidence to support the success doctors claim, there is quite a bit of evidence that suggests my suffering is the norm rather than the exception.Medical professionals would likely include me in that “silent majority,” only seeing a woman who identifies and appears typically female, graduated law school, married for over twenty years, with adopted children and a successful career. And while I have been fortunate in many ways, I no longer want my voice to be presumed buried within that silent majority. Instead, I am speaking out today to tell my story.My StoryAt age 15 I was diagnosed with amenorrhea and referred to a reproductive oncologist who told my parents I had a partially developed uterus and ovaries that would likely soon become cancerous. We were told my vagina was abnormally short and might require surgery in order to have heterosexual intercourse.Neither my parents nor I was ever told I had AIS and XY chromosomes, or that the gonads being removed were testes, not ovaries. I was told I needed a “full hysterectomy” to prevent cancer and hormone replacement therapy. That summer I spent my 16th birthday recuperating from surgery. I spent the next 25 years living a lie.A lie that has had a profound and harmful impact on me.At some level, I knew I was not being told the whole truth. My parents’ and the doctors’ actions signaled to me something more might be going on. But I was afraid to ask questions; my parents were distressed and I didn’t want to cause them any more pain. Over the years I have wondered just how much my parents knew but withheld from me (albeit with good intentions). I sensed something awful was being hidden from me, and I didn’t know whom I could trust.When I asked my doctor if I could meet someone else with my condition, I was told I was different, that there was “nobody” with my medical condition in the world, that my situation was “very rare.” I was told to get on with my life and not talk about my surgery because it wasn’t important; I was healthy and could adopt if I wanted to become a parent. I was told I must take a hormone pill each day for the rest of my life to stay healthy.But what I heard was, “you are not a real woman: you are a damaged freak, so go out and fake the rest of your life and be sure nobody knows your secret.” So that’s what I did. I was a “good girl” and took my pills, didn’t ask questions and did what the men in white coats asked me to do. There was no support provided for either my parents or me. No social workers, no therapists. Perhaps most shockingly, there was no true informed consent.A few years ago I was diagnosed with post-traumatic stress syndrome caused by anxiety I had been harboring for over two decades about my past surgery and fear of getting cancer. I decided to obtain my medical records from the hospital and discover the truth.Covering several pages of... (shrink)

The United Kingdom is the first and so far only country to pass explicit legislation allowing for the licensed use of the new reproductive technology known as mitochondrial replacement therapy. The techniques used in this technology may prevent the transmission of mitochondrial DNA diseases, but they are controversial because they involve the manipulation of oocytes or embryos and the transfer of genetic material. Some commentators have even suggested that MRT constitutes germline genome modification. All eyes were on the (...) United Kingdom as the most likely location for the first MRT birth, so it was a shock when, on September 27, 2016, an announcement went out that the first baby to result from use of the intervention had already been born. In New York City, United States-based scientist John Zhang used maternal spindle transfer to generate five embryos for a woman carrying oocytes with deleterious mutations of the mitochondrial DNA. Zhang then shipped the only euploid embryo to Mexico, where it was transferred to the mother's uterus. Zhang's team's travel across international borders to carry out experimental procedures represents a form of scientific tourism that has not been properly ethically explored; it can, however, have seriously detrimental effects for developing countries.

Mitochondrial replacement techniques have the potential to allow prospective parents who are at risk of passing on debilitating or even life-threatening mitochondrial disorders to have healthy children to whom they are genetically related. Ethical concerns have however been raised about these techniques. This article focuses on one aspect of the ethical debate, the question of whether there is any moral difference between the two types of MRT proposed: Pronuclear Transfer and Maternal Spindle Transfer. It examines how questions of identity (...) impact on the ethical evaluation of each technique and argues that there is an important difference between the two. PNT, it is argued, is a form of therapy based on embryo modification while MST is, instead, an instance of selective reproduction. The article's main ethical conclusion is that, in some circumstances, there is a stronger obligation to use PNT than MST. (shrink)

Small tandem DNA duplications in the range of 15 to 300 base‐pairs play an important role in the aetiology of human disease and contribute to genome diversity. Here, we discuss different proposed mechanisms for their occurrence and argue that this type of structural variation mainly results from mutagenic repair of chromosomal breaks. This hypothesis is supported by both bioinformatical analysis of insertions occurring in the genome of different species and disease alleles, as well as by CRISPR/Cas9‐based experimental data from different (...) model systems. Recent work points to fill‐in synthesis at double‐stranded DNA breaks with complementary sequences, regulated by end‐joining mechanisms, to account for small tandem duplications. We will review the prevalence of small tandem duplications in the population, and we will speculate on the potential sources of DNA damage that could give rise to this mutational signature. With the development of novel algorithms to analyse sequencing data, small tandem duplications are now more frequently detected in the human genome and identified as oncogenic gain‐of‐function mutations. Understanding their origin could lead to optimized treatment regimens to prevent therapy‐induced activation of oncogenes and might expose novel vulnerabilities in cancer. (shrink)

Recent studies have revealed an astonishing diversity of sex chromosomes in many vertebrate lineages, prompting questions about the mechanisms of sex chromosome turnover. While there is considerable population genetic theory about the evolutionary forces promoting sex chromosome replacement, this theory has not yet been integrated with our understanding of the molecular and developmental genetics of sex determination. Here, we review recent data to examine four questions about how the structure of gene networks influences the evolution of sex (...) determination. We argue that patterns of epistasis, arising from the structure of genetic networks, may play an important role in regulating the rates and patterns of sex chromosome replacement. (shrink)

It may be unethical to deny children with cystic fibrosis access to ethically approved clinical trials from which they might benefitDespite advances in nutritional management, aggressive antibiotic usage, and physiotherapy, cystic fibrosis remains a life limiting illness with high morbidity that imposes considerable burdens on children and families.1 Although survival to 40 years is predicted for children born in 1990s, the median age of death in 2003 was 24.2 years .The pathophysiological features of CF are produced by a defective gene (...) on chromosome 7, resulting in the defective production of a protein that regulates cellular ion transport. Defective ion transport is thought to lead to increased mucus viscosity , with poor airway clearance, recurrent bacterial infection, lung damage, and death.Gene therapy , the insertion of a normally functioning gene into deficient host cells using a suitable vector, is a potential treatment or cure for diseases produced by single gene defects—for example, CF. Gene therapy does, however, have potential or actual risks, leading many to suggest that evidence of efficacy in adults should be demonstrated before trials are conducted in children. Many serious diseases in adults such as CF have their onset in childhood. If early treatment provides greater hopes of benefit, children may be more appropriate targets for GT in CF than adults. It may be unethical to deny them access to properly constructed, ethically approved clinical trials from which they might benefit.Since research in children should be scientifically valid, in the child’s best interests, and the subject of valid consent, this article will consider these parameters in relation to trials of GT in children with CF. Because of the importance of consumer participation in the design of research we present the results of a questionnaire about GT trials delivered …. (shrink)

Independent on Sunday October 2nd One of the country's lead­ing philosophical counsellers, and chairman of the Society for Philosophy in Practice (SPP), Tim LeBon, said it typically took around six 50 ­minute sessions for a client to move from confusion to resolution. Mr LeBon, who has 'published a book on the subject, Wise Therapy, said philoso­phy was perfectly suited to this type of therapy, dealing as it does with timeless human issues such as love, purpose, happiness and emo­tional (...) challenges. `Wise Therapy, is part of a series aimed at promoting an integrative attitude as its ethos. Among all the many perspectives of psychotherapists and counselors, philosophy needs to take its place and needs to find its voice. Tim LeBon has provided an effective means by which counselors can bring philosophy into their work with clients' - APPA journal `Tim Le Bon's Wise Therapy is a comprehensible and well argued book dealing with the practical therapeutic applications of philosophical research that may well be of interest to philosophers but -- as the author himself intends -- will be of most obvious benefit to therapists and counselors, both by informing their dialogue with clients in new ways and by helping them become more informed about ways to resolve the ethical dilemmas arising within the context of their own work' - Metapsychology `A fascinating workshop for therapists and clients, backed up a thorough degree if philosophical acuity' - Journal of the Society for Existential Analysis `I strongly recommend the book for philosophers as well as practitioners, teachers, students and supervisors in counselling and psychotherapy' - Self and Society `Provides some additional and valuable arrows for the therapist's quiver' - Irvin Yalom, author of Love's Executioner `Like Aristotle, Tim LeBon examines what is said and extracts what is best from it…. There are many fascinating exercises designed to bring out and enlighten the client's values, conception of the good life, well-being, happiness, pleasure, and the proper place of reason in life…. Wise Therapy is well written and engaging. The case histories are illuminating examples of therapeutic techniques at work, the thought experiments are well designed, and the philosophical position adapted from the internal debates of the philosophers is level headed…. I recommend it highly to philosophers with an interest in counselling, and psychological counsellors with an interest in philosophy' - Jeff Mason, The Philosophers' Magazine `Tim LeBon has… authored a text which should become a staple on the philosophical counsellor's bookshelf…. Wise Therapy is a concise, well-written book…. His ability to relate philosophical concepts to counselling concerns is admirable and attests to the skill and knowledge he possesses as a working counsellor. But, by far the most important part of Tim LeBon's book to PC is the last chapter, "The Counsellor's Philosophical Toolbox"' - Craig Munns in The Examined Life ` Tim LeBon has done a good job of offering practical approaches to some of the most important and vexing issues that arise in counselling…. Tim LeBon's book contains helpful suggestions, practical information, and useful examples, and would make a good addition to the library of any counsellors willing to allow philosophy to turn mere client sessions into wise therapy' - Peter Raabe, Practical Philosophy Wise Therapy is an original and practical guide to how philosophy can benefit counselling and psychotherapy. Tim LeBon argues that therapy, informed by philosophy, can help clients make better decision and achieve emotional wisdom. He uses philosophical approaches to explore issues of right and wrong, the emotions and reasons, well-being and the meaning of life, and develops a 'counsellor's toolbox' of techniques that can help practitioners apply the wisdom of philosophy to good therapeutic practice. For counsellors who may find philosophical approaches to therapy useful, this work addresses key philosophical topics - the emotions, free will, the meaning of life and ethics. It is jargon-free where possible and assumes no previous philosophical training. From The Independent, 16th November 2004 Plato is my agony aunt It was the end of a love affair that broke her heart. Could the wisdom of the great philosophers show her how to be happy again? Claire Smith tries a novel form of therapy "The unexamined life is not worth living," Socrates said. Nor is the life you're left with after your boyfriend has left you for another woman - at least, that's how it felt in October last year when mine broke rank and went off with an art student from Cleveland, Ohio. We were over there for the opening of his new art exhibition. He'd flown over four days before me and had met her at a party. Supposedly, they "connected". The five months that followed were a roller-coaster of confusion, vitriol and despair. I knew there'd been problems in our relationship. We saw the world very differently; he delighted in the charm of the ordinary, I wanted maximum divinity. He walked; I galloped. He drank tea; I loathed the stuff. But, along the banks of the Thames, we'd made a promise to always stick together. Our love was something unique: "transcendental", I called it. And besides, we recycled. Surely a commitment to save the world would save our relationship? Alas, no. So there I was, a woman scorned. Hell truly hath no greater fury. And what made it worse was that I still believed in our transcendental love. If I wanted to change the way I was feeling, I needed to alter the way I was thinking. But how? A few bottles of wine and a sharp blow to the head might have done the trick. Fortunately, there's an older, more trusted way of turning your head on its head that counsellors are starting to use: philosophy. The idea of employing Plato as an agony aunt was begun in 1981 by the German philosopher Gerd Achenbach. Although philosophy spends a lot of its time asking real-life questions that affect real-life people - What is happiness? And is it always wrong to lie? - most of the debate goes on in ivory towers. What Achenbach and subsequent philosophers including Tim LeBon, the chairman of the UK's Society for Philosophy in Practice, wanted to do was "give practical application" to this gigantic library of great thoughts. So how does it work? Like most types of therapy, you sign up for a set of sessions. "Two would give you a new perspective on one issue; six would help you to make a major life-decision, like a career change; with 12 you can start to rethink your entire life philosophy," explains LeBon. Each session lasts 50 minutes and costs £50 - and, no, you don't have to have any previous knowledge of philosophy. "If you think of Friends, it would suit Ross and Chandler more than Joey," LeBon says. "It's for anyone who wants to make their emotions more intelligent. Or for those who have tried other kinds of therapy, and want something more cerebral." The first session begins with the patient venting off about whatever's troubling them. The rant over, the counsellor then picks out some key concepts that are crucial to the problem - in the case of heartbreak, it is love and happiness that come hurtling to the fore - and then gets the patient to define what they mean. So, what is love? What is happiness? To kick-start the patient's thinking, LeBon describes what a great philosopher had to say about it. In my case, he tells me what Plato wrote about love in his Symposium: that to stop man fighting the gods, Zeus decided to cut each human in two, so they would lose their strength. "This, then, is the source of our desire to love each other," Plato said. "Each of us is a 'matching half' of a human whole, because each was sliced like a flatfish, two out of one, and each of us is always seeking the half that matches him." This method of probing what we might think are "obvious" ideas, such as love and happiness, was devised by Socrates in the squares of Athens. "The only I thing I know is that I know nothing at all," he boasted. What Socrates showed was that although many of the thinkers of his time thought they knew what justice, happiness and goodness meant, their understanding was tied in to their personal agenda and world view, and, what's more, when pushed, their ideas often contradicted themselves. A bit like me on love. Whereas part of my understanding of love was something that gave life meaning, made it worth living and bound us together, I also believed that true love was "transcendental": that it was out of this world, and it didn't matter if the two people who loved each other couldn't get along in the day-to-day. Love was bigger than the mundane. But when it came to the next stage of the therapy, critical thinking - "to check out whether your assumptions stand up to examination" - I walked head first into a contradiction. If I think love's purpose is to make life worth living, but then say it's irrelevant to daily life, surely my two ideas of love are not compatible? As the cogs in my brain start to creak into motion, I feel myself taking a step back from my predicament: thinking about how I've been thinking. This idea I had of transcendental love might have started off as a romantic dream. But when the relationship stopped working, and I found myself feeling trapped and frustrated, I used it to justify the mechanics of a relationship that just didn't work in the daily grind. I used it to lie to myself. In the final stage, LeBon gets me to start thinking about how to go forward. "You can't change what has happened," he says. "You can't change that he's left you, or how you behaved in the relationship. So, as the Stoics did, let's work on controlling the controllables: the things that you can change." To work out what can be changed, he gets me to try out a thought experiment, a method often used in philosophy to imagine other worlds where people can have different codes of behaviour. Thought experiments shatter your preconceived ideas of how the world should be and let your imagination run wild to how the world could be. "I find Viktor Frankl very useful here, the Austrian psychiatrist and concentration-camp survivor who actually believed that everything in life happens for a purpose," LeBon says. "Suppose this break-up did happen for a reason that will work to your benefit," he suggests. "What might that be? The answer might be that you can now focus on something important that was denied in the relationship. Or - the Hollywood version - so you'll meet someone who is really right for you." Temporarily freed of any sense of responsibility for the relationship that was, and its sorry demise, the list came fast. I could now travel more; he didn't like me travelling on my own, but too often he didn't want to go anywhere, preferring to stay in his studio and make art. I'd love to meet someone with a similar sense of adventure to mine. For the first time in two years, I was being honest with myself about what I really wanted - listening to those voices that we all have inside our heads, and too often try to muzzle. So did philosophy save me? Well, I'm now dating a travel writer I have to run to keep up with. I still haven't got over the fact that my replacement came from Cleveland, Ohio. But I guess I never will.

But there is also always some reason in madness" - Friedrich Nietzsche · "That man shall live as his own master and in happiness who can say each day 'I have lived'" - Horace · "The good of man is the active exercise of his soul's faculties in conformity with excellence or virtue... Moreover this activity must occupy a complete lifetime; for one swallow does not make spring, nor does one fine day; and similarly one day or a brief period of happiness does not make a man supremely blessed and happy" - Aristotle · "There is nothing on this earth more to be prized than friendship" - Thomas Aquinas · "Whatever you do... love those who love you" - Voltaire · "Happiness is not an ideal of reason but of imagination" - Immanuel Kant · "Happiness is a state of which you are unconscious.

Marriage is a real thing" - Johann Wolfgang von Goethe I shrink, therefore I am Therapy has many answers, but some questions require the help of a philosopher, says Clint Witchalls Sunday November 21, 2004 The Observer Danny had worked in the City of London for 10 years. As a research analyst, stockbroker and fund manager, he'd made a lot of valuable contacts, earnt a lot of cash, and learnt some important business skills. However, as he approached his mid-thirties, he no longer felt good about himself or what he did for a living, and he found his colleagues cold and unfriendly. A chronic illness made him realise his mortality, and he began to reassess his priorities. Danny had been struggling with his career conundrum for nearly five years when he met David Arnaud, a philosophical counsellor. After a few soul-searching sessions, Danny arrived at a decision. Today, he teaches economics to sixth-formers, and he loves it. 'It's a much better lifestyle,' he says. Many people are turning to philosophical counsellors to get answers to questions such as: 'How do I make sense of myself?' 'What is important to me?' 'Where am I going?' These are perhaps not the sort of questions that require psychiatric intervention, but Arnaud, who recently completed the first empirical study of philosophical counselling in the UK, has found that within just five sessions the majority of clients, with important decisions to make, tend to move from a state of concern and confusion to a resolution. Modern philosophical counselling can be traced back to 1981, when the philosopher Gerd Achenbach opened the first practice near Cologne. Achenbach referred to the new discipline as 'therapy for the sane.' Today, there are hundreds of philosophical counsellors around the world, with the movement particularly strong in the US, Britain and the Netherlands. 'The dilemmas people face aren't always primarily psychological,' says Alex Howard, a philosophical counsellor from Newcastle. 'If people face problems that are social or economic, it doesn't make sense to define their problems in purely psychological terms.' Tim LeBon, a founder member of the Society for Philosophy in Practice (SPP) and author of Wise Therapy, adds: 'We are faced with far more life choices than our grandparents, yet have far fewer resources to deal with them. Our grandparents may have gone to a priest or to other family members for advice; most people don't trust these solutions any more and so want to make their own well-informed, well thought-out choices. Philosophical counselling can help these people - people in mid-life crises who are wondering how to make the most of the rest of their life. People who want to take stock of their values.' Where stressed executives might once have been prescribed a course of tranquillisers or antidepressants, they can now get a dose of Bertrand Russell instead: 'Success is too dearly purchased if all the other ingredients have been sacrificed to obtain it.' While some philosophical counsellors do recommend books for their clients to read, most sessions are about helping the client identify faulty thoughts. For example, a briefing in Aristotelian logic might show a client why their beliefs are erroneous. The person might infer that they're a screw-up because they've screwed up. The counsellor could point out that they're making an error called 'fallacy of composition' - that is, what's true of the part isn't necessarily true of the whole. In philosophical counselling, problems aren't pathologised as they are by the psychiatric profession, and the dialogue between client and counsellor is more like a meeting of equals, compared to many therapies where the client is treated like a patient and seen as someone who is, in some way, inadequate. 'Anybody can benefit from philosophical counselling,' says Howard. 'But it does require someone who is willing to take stock.' Lou Marinoff, author of international bestseller Plato Not Prozac! has done much to promote philosophical counselling. 'Some people who have stabilised their neurochemistry and validated their emotions now wish to examine or re-examine the criteria of their beliefs, the principles of their conduct, or the meaning of their lives,' he says. 'With whom shall they do this? Psychologists and psychiatrists can shed light on such issues - as can rabbis, priests, imams and gurus. Philosophers are now rejoining the ranks of helpers.' LeBon believes certain therapies (such as cognitive behavioural therapy) don't go far enough in helping their clients. 'For instance, if you are anxious about your relationship, a cognitive therapist would try to dispute your catastrophising and jump to conclusions to make you feel less anxious,' says LeBon. 'A philosophical counsellor would do this, but would also look for existential meaning in your anxiety - perhaps you really don't want to be in the relationship and that is what your anxiety is telling you.' LeBon also gives short shrift to psychoanalysts. 'There's very little evidence for the Freudian unconscious, and it's time to move on to more intellectually satisfying and helpful therapies,' he says. However, Alain de Botton, the man who popularised philosophy as self-help, isn't ready to bury psychologists and their ilk just yet. 'The truth is that psychoanalysis grew out of philosophy - it's not some completely new idea, and in fact, done properly, psychoanalysis is philosophical anyway. It may even be dangerous to the mental health of some people to suggest a philosopher rather than a properly trained analyst. The knowledge of analysts when it comes to many emotional problems is now much greater than that of most philosophers.' Guardian Unlimited © Guardian Newspapers Limited 2004. (shrink)

Mitochondrial replacement therapy requires oocytes of women whose mitochondrial DNA will be transmitted to resultant children. These techniques are scientifically, ethically and socially controversial; it is likely that some women who donate their oocytes for general in vitro fertilisation usage would nevertheless oppose their genetic material being used in MRT. The possibility of oocytes being used in MRT is therefore relevant to oocyte donation and should be included in the consent process when applicable. In present circumstances, specific consent (...) should be obtained. However, once MRT becomes more routine, such consent could be incorporated into the general consent process for oocyte donation. The reported lack of proper consent for MRT from the oocyte donor in the first baby born via the technique is an ethical failing and should be corrected in any future practice of MRT. (shrink)

Jürgen Habermas is regarded as a central bioconservative commentator in the debate on the ethics of human prenatal genetic manipulations. While his main work on this topic, The Future of Human Nature, has been widely examined in regard to his position on prenatal genetic enhancement, his arguments regarding prenatal genetic therapeutic interventions have for the most part been overlooked. In this work I do two things. First, I present the three necessary conditions that Habermas establishes for a prenatal genetic manipulation (...) to be regarded as morally permissible. Second, I examine if mitochondrial replacement techniques meet these necessary conditions. I investigate, specifically, the moral permissibility of employing pronuclear transfer and maternal spindle transfer. I conclude that, according to a Habermasian perspective on prenatal genetic manipulation, maternal spindle transfer and pronuclear transfer are morally impermissible. Maternal spindle transfer is, in principle, morally permissible, but only when we have beforehand preselected a sperm and an egg for our reproductive purpose. These findings are relevant for bioconservatives, both for those who hold a Habermasian stance and for those who hold something akin to a Habermasian stance, because they answer the question: what should bioconservatives do regarding mitochondrial replacement techniques? In fact, the answer to this question does not only normatively prescribe what bioconservatives should do in terms of their personal morality, but it also points towards what kind of legislation regulating mitochondrial replacement techniques they should aim at.
