Abstract
PURPOSE Preimplantation Genetic Testing (PGT) has attracted considerable ethical, legal, and social scrutiny, but academic debate often fails to reflect clinical realities. METHODS Addressing this disconnect, a review of 506 articles from 1999 to 2019 across humanities and social sciences was conducted to synthesize the Ethical, Legal, and Social Implications (ELSI) of PGT. This review mined PubMed, WoS, and Scopus databases, using both MeSH terms and keywords to map out the research terrain. RESULTS The findings reveal a tenfold increase in global research output on PGT's ELSI from 1999 to 2019, signifying rising interest and concern. Despite heightened theoretical discourse on selecting "optimal" offspring, such practices were scarcely reported in clinical environments. Conversely, critical issues like PGT funding and familial impacts remain underexplored. Notably, 86% of the ELSI literature originates from just 12 countries, pointing to a research concentration. CONCLUSION This review underscores an urgent need for ELSI research to align more closely with clinical practice, promoting collaborations among ethicists, clinicians, policymakers, and economists. Such efforts are essential for grounding debates in practical relevance, ultimately steering PGT towards ethical integrity, societal acceptance, and equitable access, aiming to harmonize PGT research with real-world clinical concerns, enhancing the relevance and impact of future ethical discussions.

Limitations, concerns and potential: attitudes of healthcare professionals toward preimplantation genetic testing using polygenic risk scores. Eur J Hum Genet 2023; 31:1133-1138. [PMID: 36935419 PMCID: PMC10545753 DOI: 10.1038/s41431-023-01333-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 02/08/2023] [Accepted: 03/07/2023] [Indexed: 03/21/2023] Open
Abstract
Preimplantation genetic testing using polygenic risk scores (PGT-P) has recently been introduced. However, PGT-P has been met with many ethical concerns. It is therefore important to get insights into the perspectives of stakeholders regarding PGT-P. We performed a qualitative interview study on the views of healthcare professionals toward PGT-P. We conducted in-depth semi-structured interviews with 31 healthcare professionals working in the field of preimplantation genetic testing. The interviews explored the attitudes of healthcare professionals toward the technology of PGT-P, e.g., the validity, utility, limitations and potential benefits of PGT-P. We found that most healthcare professionals were concerned about the prematurity of introducing PGT-P into clinical practice. They had various ethical considerations, such as concerns related to validity and utility of PGT-P, limited embryos and options, and difficulties for prospective parents regarding comprehension and informed decision-making. Positive aspects were also identified, e.g., regarding reproductive autonomy and potential health benefits. Overall, most healthcare professionals considered that clinical implementation of PGT-P is premature. More comprehensive, longitudinal and inclusive studies are needed first, though these might not improve PGT-P enough to responsibly implement it. Healthcare professionals were also concerned that PGT-P could cause anxiety and create difficult choices for prospective parents. These perspectives and ethical considerations are crucial to consider for future guidelines and recommendations regarding PGT-P.

Clinical Outcome, Socioeconomic Status and Psychological Constrains of Patients Undergoing Preimplantation Genetic Testing (PGT) in Northern Greece. Medicina (B Aires) 2022; 58:medicina58101493. [PMID: 36295653 PMCID: PMC9611400 DOI: 10.3390/medicina58101493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 09/07/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022] Open
Abstract
Background and objectives: Preimplantation genetic testing (PGT) offers patients the possibility of having a healthy baby free of chromosomal or genetic disorders. The present study focuses on the application of PGT for patients located in Northern Greece, investigating their clinical outcomes, their motives, and their overall physical and emotional experience during the treatment, in association with their socioeconomic background. Materials and Methods: Couples who underwent PGT for a monogenic condition (PGT-M, n = 19 cycles) or aneuploidy (PGT-A, n = 22 cycles) participated in the study. Fertilization, implantation, and pregnancy rates were recorded for all cycles. The couples were asked to fill in a questionnaire about the consultation they had received prior to treatment, their sociodemographic information, and the psychological impact PGT had on both the female and male partner. Results: The fertilization, implantation, and ongoing pregnancy rates for the PGT-M and PGT-A cycles were 81.3%, 70.6%, and 52.9%, and 78.2%, 64.3%, and 57.1%, respectively. Females experienced more intense physical pain than their male partners while psychological pain was encountered by both partners and occasionally in higher instances in males. No typical socioeconomic background of the patients referred for PGT in Northern Greece was noticed. Conclusion: PGT is an attractive alternative to prenatal diagnosis (PND), aiming to establisha healthy pregnancy by identifying and avoiding the transfer of chromosomally or genetically abnormal embryos to the uterus. Although the benefits of PGT were well-received by all patients undergoing the procedure, psychological pain was evident and especially prominent in patients with a previous affected child or no normal embryos for transfer. Holistic counseling is of utmost importance in order to make patients' experience during their journey to have a healthy baby less emotionally demanding and help them make the right choices for the future.

Decision-making and experiences of preimplantation genetic diagnosis in inherited heart diseases: a qualitative study. Eur J Hum Genet 2022; 30:187-193. [PMID: 34545210 PMCID: PMC8821668 DOI: 10.1038/s41431-021-00963-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 07/15/2021] [Accepted: 09/07/2021] [Indexed: 02/03/2023] Open
Abstract
Preimplantation genetic diagnosis (PGD) ensures a disease-causing variant is not passed to the next generation, including for inherited heart diseases. PGD is known to cause significant emotional burden, but little is known about how parents experience PGD to select against inherited heart disease. We aim to understand how people with inherited heart disease, and their partners, experience and make decisions about PGD. Participants were recruited from a specialised inherited heart disease clinic. Qualitative semi-structured interviews were conducted with adult participants who had considered PGD. A semi-structured interview schedule explored overall experiences and reasons for undergoing PGD. Broad topics included experience of disease, reproductive history, psychosocial and financial considerations. Interviews were recorded, transcribed verbatim and thematically analysed using a framework method. Twenty participants were included (15 with inherited cardiomyopathy, 3 with inherited arrhythmia syndrome and 2 partners). In contemplating PGD, participants considered 3 main issues: past experience of disease e.g. sudden cardiac death, sport restrictions and clinical heterogeneity; intergenerational responsibilities; and practical considerations such as finances and maternal age. Among those who chose to undergo PGD (n = 7/18), past experience of a significant cardiac event, such as family history of sudden cardiac death, was important in the decision process. The decision to undergo PGD for inherited heart disease is complex and influenced by individual values and experience of disease. We highlight key areas where further discussion may assist in PGD decision processes.

Abstract
This study examined perspectives on the ethical implications of preimplantation genetic testing (PGT) among individuals who actually (not hypothetically) used or considered using PGT. Most of the prior patient-centered research on PGT ethics used qualitative designs (9 out of the 11 articles) and focused only on single gene testing. This cross-sectional study used an anonymous online questionnaire; 15 items assessed potential ethical concerns involved in PGT decision-making, including clinical indications for PGT, the greater implications of PGT for society, and unused embryo disposition. N = 207 individuals (mean female/male age 35.7/38.9 years, 21% Hispanic or non-White) who had recently used or considered using PGT for single gene (60%) or for chromosomal testing (40%) completed the questionnaire. Most respondents supported PGT screening for disease conditions with childhood or adult onset that are untreatable (64%-85% across items); most opposed PGT for trait selection (76%-81%). Most respondents agreed that PGT aids in parental decision-making (66%-67%), although some expressed concern over potential unforeseen consequences (25%-30%). Regarding disposition of embryos without known genetic abnormalities, most respondents favored freezing indefinitely (86%) or donating to another family (69%), while for embryos with genetic abnormalities, most respondents favored donating to research (78%) or destroying them (62%). Stratification by religious affiliation revealed several differences, such as less acceptance of PGT for diseases that occur in adulthood and have no treatment options among Protestants (p = .015) and greater willingness to donate surplus embryos to research among participants without a religious affiliation (p < .001). These results are limited by the relatively homogeneous sample of participants (mostly White, married, and predominantly college-educated). In summary, participants who considered/used PGT found PGT acceptable overall for screening for disease conditions; most opposed using PGT for trait selection. Our novel questionnaire provides a structured tool for assessing the ethical perspectives surrounding the use of PGT.

A review on the motivations, decision-making factors, attitudes and experiences of couples using pre-implantation genetic testing for inherited conditions. Hum Reprod Update 2021; 27:944-966. [PMID: 33969393 DOI: 10.1093/humupd/dmab013] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 02/13/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND In pre-implantation genetic testing (PGT), fertile couples undergo IVF with genetic testing of embryos to avoid conceptions with a genetic condition. There is an exponentially increasing uptake with over 600 applications listed by the Human Fertilisation and Embryology Authority in the UK. The psychological aspects of the decision-making process and the experience of PGT, however, are relatively underevaluated, with the potential to leave patients unsupported in their journeys. OBJECTIVE AND RATIONALE In this review, we aim to comprehensively report on every aspect of couples' experiences of PGT. We consider what motivates users, the practical and ethical decisions involved and how couples navigate the decision-making process. Additionally, we report on the social and psychological impact on couples who are actively undergoing or have completed the PGT process. SEARCH METHODS A systematic search of English peer-reviewed journals of three computerized databases was undertaken following PRISMA guidelines. Studies that examined the motivations, attitudes, decision-making factors and experiences of patients who have been actively engaged in the PGT process were included. No restrictions were placed on study design or date of publication. Studies examining patients using PGT in a hypothetical context or solely using PGT for aneuploidy were excluded. Qualitative data were extracted using thematic analysis. OUTCOMES The main outcomes were patient motivations, deciding factors and attitudes, as well as the patient experience of coming to a decision and going through PGT.Patients were primarily motivated by the desire to have a healthy child and to avoid termination of pregnancy. Those with a sick child or previous experience of termination were more likely to use PGT. Patients also felt compelled to make use of the technology available, either from a moral responsibility to do so or to avoid feelings of guilt if not. The main factors considered when deciding to use PGT were the need for IVF and the acceptability of the technology, the financial cost of the procedure and one's ethical standpoint on the creation and manipulation of embryos. There was a general consensus that PGT should be applied to lethal or severe childhood disease but less agreement on use for adult onset or variable expression conditions. There was an agreement that it should not be used to select for aesthetic traits and a frustration with the views of PGT in society. We report that couples find it difficult to consider all of the benefits and costs of PGT, resulting in ambivalence and prolonged indecision. After deciding on PGT use, we found that patients find the process extremely impractical and psychologically demanding. WIDER IMPLICATIONS This review aimed to summarize the current knowledge on how patients decide to use and experience PGT and to make suggestions to incorporate the findings into clinical practice. We cannot stress enough the importance of holistic evaluation of patients and thorough counselling prior to and during PGT use from a multidisciplinary team that includes geneticists, IVF clinicians, psychologists and also patient support groups. Large prospective studies using a validated psychological tool at various stages of the PGT process would provide an invaluable database for professionals to better aid patients in their decision-making and to improve the patient experience.

Kilbride MK. In vitro fertilisation with preimplantation genetic testing: the need for expanded insurance coverage. JOURNAL OF MEDICAL ETHICS 2020; 47:medethics-2019-105879.

Abstract
Technological advances in genetic testing have enabled prospective parents to learn about their risk of passing a genetic condition to their future children. One option for those who want to ensure that their biological children do not inherit a genetic condition is to create embryos through in vitro fertilisation (IVF) and use a technique called preimplantation genetic testing (PGT) to screen embryos for genetic abnormalities before implantation. Unfortunately, due to its high cost, IVF-with-PGT is out of reach for the vast majority of Americans. This article addresses an issue that has been underexplored in the medical ethics literature: the lack of insurance coverage for IVF-with-PGT.Within the US system, a key concept in insurance is that of medically necessary care, which broadly consists of diagnostic services and treatment services. In this article, I argue that IVF-with-PGT could be classified as either a diagnostic service or as a treatment service. To make this case, I show that IVF-with-PGT is similar to other types of services that are often covered by US insurance providers. In light of these similarities, I argue that the current system is inconsistent with respect to what is-and is not-covered by insurance. To promote consistency and fairness in coverage, like cases should be treated alike-starting with greater coverage for IVF-with-PGT.

Abstract
PURPOSE The decision to undergo preimplantation genetic testing (PGT) entails a variety of personal and societal variables. Although PGT technology is widely accepted and used, few studies have queried the motives and concerns of PGT users; moreover, in-depth qualitative data regarding the PGT experience is scant. METHODS In order to explore and analyze the experience, concerns, expectations, and attitudes toward the PGT technique and its implications, semi-structured interviews were conducted in a single tertiary medical center with 43 Israeli PGT users for HLA matching and autosomal dominant, autosomal recessive, and X-linked genetic disorders. RESULTS The primary considerations in choosing PGT were prevention of birth of a child who would suffer a terminal or chronic disease as well as abrogation of a familial genetic condition. Religion played a decisive role in accepting PGT as an antenatal option. Regarding satisfaction with the PGT experience, many interviewees highlighted the need for greater attention to be given to potential stages of failure throughout the procedure and the need for emotional support. Our clinical results regarding implantation rate and cumulative live birth rate are 38-40% and 27-30%, respectively. CONCLUSION This survey broadens understanding of the specialized needs of women, couples, and minority groups undergoing PGT and underscores the relevance of counseling services for PGT users.

Abstract
Preimplantation genetic testing (PGT) is an alternative reproductive technology integrated with in vitro fertilization (IVF). It is a well-established technique offering a reproductive option for families at a high risk of transmitting a genetic disorder, allowing them to avoid making a decision about termination of an affected pregnancy (TOP). In Arab communities and particularly in Oman, where TOP is not favored under the majority of implemented Muslim law, termination of pregnancy for fetal indications is not always possible. As these communities are in favor of consanguineous marriage, they are at increased risk of serious and lethal autosomal recessive conditions, and as a result, PGT is a feasible option as a TOP decision can be avoided. However, undergoing PGT is relatively new in the Arab Muslim countries and Omani patients have only recently had access to the service. This qualitative study utilized a phenomenological approach to explore the experience of Omani families who had selected to undergo PGT as a means of reducing the risk of having a child affected with a genetic disorder. Fourteen participants from eight families who underwent PGT were interviewed. Data collected were analyzed using thematic analysis. The research identified four main themes: Anxiously waiting 'Taraqub'; Unforeseen; Secrecy; and Me and My Partner. The findings of the research have provided insight into the PGT experiences of Omani families. Unique cultural and religious perspectives should be considered when counseling Omani Muslim couples.

Abstract
OBJECTIVE To analyze psychometric properties of two novel instruments assessing decisional distress and uncertainty experienced by individuals considering preimplantation genetic testing (PGT). METHODS The new PGT Decisional Distress instrument (22 items) assesses negative/positive emotions. The new PGT Decisional Uncertainty instrument assesses Clarity about test benefits/disadvantages (5 items) and Certainty of having adequate information/support to make a good decision (7 items). Scales ranged from 0 to 4. Psychometrics (central tendencies, internal consistency reliability, and discriminant validity) were evaluated. Stratified analysis by decision stage was conducted. All participants had considered or used PGT in the previous 6 months. RESULTS N = 106 females (mean age 36.5 ± 4.8 years; 16% non-Caucasian; 9% Hispanic) across 16 US states completed an online anonymous questionnaire. On average, respondents reported minimal distress (mean 0.96), high clarity (mean 3.26), and high certainty (mean 3.06), particularly those who had already decided compared to undecided women (P ≤ .02). Instruments had excellent internal consistency (Cronbach's α's 0.92-0.94) and displayed sufficient inter-individual variability (SD's 0.75-0.89). Correlations confirmed expected patterns of association between instruments (P's < .01), indicating discriminant validity. CONCLUSION We document initial reliability and validity of new instruments to measure emotional distress and uncertainty in female patients who have recently considered PGT for single-gene or chromosomal disorders.

Abstract
Purpose This study aims to describe the motives and considerations of couples carrying a structural chromosomal abnormality deciding on preimplantation genetic testing (PGT). Methods A qualitative exploratory study was conducted using semi-structured dyadic interviews with 13 couples (N = 26) carrying a structural chromosomal abnormality. All couples had an informative consultation in our PGT centre in the Netherlands. Results Almost all couples considered PGT or natural conception combined with prenatal diagnosis (PND) as the only two reproductive options. Among several considerations mentioned, the majority indicated that the wish to increase the chance of a successful pregnancy was the most important motive to opt for PGT. All couples who opted for PGT had first tried to conceive spontaneously and entered the PGT programme because of their adverse experiences during these attempts (infertility, recurrent miscarriage, termination of pregnancy, birth of an affected child). Couples that refrained from PGT were of advanced maternal age and expressed the long trajectory of PGT as the main reason to refrain. If conceiving spontaneously would not lead to an ongoing pregnancy, these couples also indicated that they would use PGT. Conclusion This study shows that couples carrying a structural chromosomal abnormality consider PGT and spontaneous conception with PND as relevant reproductive options. They are looking for the option that is in their opinion the fastest way to establish a successful pregnancy. Information on the perceived pros and cons of PGT or spontaneous conception in these couples can help to optimize counselling and psychological support during the decision-making process.

Patients' preimplantation genetic testing decision-making experience: an opinion on related psychological frameworks. Hum Reprod Open 2019; 2019:hoz019. [PMID: 31598567 PMCID: PMC6777985 DOI: 10.1093/hropen/hoz019] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Revised: 06/24/2019] [Accepted: 07/01/2019] [Indexed: 12/18/2022] Open
Abstract
The process of deciding whether to pursue preimplantation genetic testing (PGT) of an embryo is highly stressful for individuals and couples and has adverse emotional consequences (e.g. distress and uncertainty). PGT influences patients’ lives in both positive and negative ways and is experienced at an individual level, as a dyadic unit, as a family member and as part of the society. Here, we argue that providing a conceptual framework with which to understand the `experience of decision making’ about PGT for monogenic disease (PGT-M) testing specifically, as well as the factors contributing to `decisional distress’ and `uncertainty’ that patients endure as a result—apart from what decision they make—is crucial to optimizing patient counseling, satisfaction and outcomes in the field of ART. Derived from psychological theory, the framework proposed here identifies three categories of contributing factors to decisional distress and uncertainty in considering PGT-M; namely, ‘intraindividual’, ‘interpersonal’ and ‘situational’ factors. We reviewed evidence from the PGT literature to inform our framework. Well-accepted theories of stress and health decision making were also reviewed for their relevance to PGT-M decision making, focusing on potential distress and uncertainty. Our novel conceptual framework can be used to inform clinical practice, to advance research and to aid the development of interventions for individuals and couples who are deciding whether or not to use PGT-M. Alleviating emotional distress and uncertainty can improve patients’ well-being during their reproductive journey.

Abstract
AIM Increasing preimplantation genetic testing (PGT) cycles are being performed in Hong Kong. This study aims to evaluate the knowledge, attitude and ethical consideration of Chinese couples toward PGT. METHODS Couples requesting PGT between June 2013 and March 2014 were invited to complete a questionnaire. RESULTS Total 49 couples (49 women, 47 men) completed the questionnaires. Eighteen couples (37%) were waiting for PGT (pre-PGT group), 15 couples (31%) were undergoing PGT (PGT group) and 16 couples (32%) had completed at least one PGT cycle (post-PGT group). Only 53% of the couples could tell the recurrent risk, and 31% (with monogenic disorders) could tell the mode of inheritance of their condition. The acceptability of PGT (>80%) and attitude toward the embryo fate (58-78%) were good. The post-PGT group had more concern than the PGT and pre-PGT groups on the prenatal diagnostic testing (**P = 0.007). 12.5% of the couples worried about the transfer of healthy embryos with carrier state and they all had monogenic disorders. If the prenatal testing confirmed an affected fetus, a higher percentage (32%) in the Post-PGT group disagreed to terminate the pregnancy in contrast to a much lower 6% in the pre-PGT group (**P = 0.02). Three-quarter of the couples opted to tell their child about their conception through PGT. CONCLUSION Chinese couples in Hong Kong had an overall good acceptability and positive attitude toward PGT. We appreciate the difficulties the couples have gone through PGT. A checklist on what to cover pre-during-post-PGT in the counseling process is needed.

Abstract
The increasing technical complexity and evolving options for repro-genetic testing have direct implications for information processing and decision making, yet the research among patients considering preimplantation genetic diagnosis (PGD) is narrowly focused. This review synthesizes the literature regarding patient PGD decision-making factors, and illuminates gaps for future research and clinical translation. Twenty-five articles met the inclusion criteria for evaluating experiences and attitudes of patients directly involved in PGD as an intervention or considering using PGD. Thirteen reports were focused exclusively on a specific disease or condition. Five themes emerged: (1) patients motivated by prospects of a healthy, genetic-variant-free child, (2) PGD requires a commitment of time, money, energy and emotions, (3) patients concerned about logistics and ethics of discarding embryos, (4) some patients feel sense of responsibility to use available technologies, and (5) PGD decisions are complex for individuals and couples. Patient research on PGD decision-making processes has very infrequently used validated instruments, and the data collected through both quantitative and qualitative designs have been inconsistent. Future research for improving clinical counseling is needed to fill many gaps remaining in the literature regarding this decision-making process, and suggestions are offered.

Abstract
Fanconi anemia (FA) is characterized by congenital malformations, progressive bone marrow failure, and predisposition to malignancy. Hematopoietic stem cell transplantation is used to treat FA, and best results are attained with sibling donors who are human leukocyte antigen (HLA) identical matches. Preimplantation genetic diagnosis (PGD) offers parents of an affected child the opportunity to have an unaffected child who is an HLA match. While some research has investigated parents' experiences during the PGD process, no published studies specifically address factors influencing their decision-making process and long-term interpersonal outcomes. The aims of this study are to: (1) examine parents' expectations and the influence of media, bioethics, and religion on their decision to undergo PGD; (2) examine parents' social support and emotional experiences during their PGD process; and (3) characterize long-term effects of PGD on relationship dynamics (partner, family, friends), others' attitudes, and parental regret. Nine parents participated in semi-structured interviews. Thematic analysis revealed their decision to use PGD was variously influenced by media, bioethics, and religion, in particular, affecting parents' initial confidence levels. Moreover, the PGD process was emotionally complex, with parents desiring varying amounts and types of support from different sources at different times. Parents reported others' attitudes towards them were similar or no different than before PGD. Parental regret regarding PGD was negligible. Results of this study will promote optimization of long-term care for FA families.

Abstract
Preimplantation genetic diagnosis (PGD), a form of assisted reproductive technology, is a new technology with limited awareness among health care professionals and hereditary cancer families. Nurses play a key role in the care of patients and are often in an ideal position to discuss and refer patients on sensitive quality of life issues, such as PGD. Two hundred and one nurses at Moffitt Cancer Center (MCC) responded to an online survey assessing knowledge and educational needs regarding PGD and families with hereditary cancer. The majority of respondents were female (n = 188), white (n = 175), had an RN/BSN degree (n = 83), and provided outpatient care at the cancer center (n = 102). More than half of respondents (78%) were unfamiliar with PGD prior to the survey and respondents who had heard of PGD had limited knowledge. More than half of the participants reported PGD was an acceptable option for families with hereditary cancer syndromes and thought individuals with a strong family or personal history should be provided with information about PGD. This study indicates that oncology nurses may benefit from and desire education about PGD. With advances in reproductive technology and options, further PGD education is needed among healthcare professionals. An examination of current oncology nursing curriculum and competencies regarding genetic education may identify need for future revisions and updates.

Abstract
STUDY QUESTION What do scientists in the field of preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS) consider to be the future direction of comprehensive embryo testing? SUMMARY ANSWER Although there are many biological and technical limitations, as well as uncertainties regarding the meaning of genetic variation, comprehensive embryo testing will impact the IVF/PGD practice and a timely ethical reflection is needed. WHAT IS KNOWN ALREADY Comprehensive testing using microarrays is currently being introduced in the context of PGD and PGS, and it is to be expected that whole-genome sequencing will also follow. Current ethical and empirical sociological research on embryo testing focuses on PGD as it is practiced now. However, empirical research and systematic reflection regarding the impact of comprehensive techniques for embryo testing is missing. STUDY DESIGN, SIZE AND DURATION In order to understand the potential of this technology and to be able to adequately foresee its implications, we held an expert panel with seven pioneers in PGD. PARTICIPANTS/MATERIALS, SETTING, METHODS We conducted an expert panel in October 2011 with seven PGD pioneers from Belgium, The Netherlands, Germany and the UK. MAIN RESULTS AND THE ROLE OF CHANCE Participants expected the use of comprehensive techniques in the context of PGD. However, the introduction of these techniques in embryo testing requires timely ethical reflection as it involves a shift from choosing an embryo without a particular genetic disease (i.e. PGD) or most likely to result in a successful pregnancy (i.e. PGS) to choosing the best embryo based on a much wider set of criteria. Such ethical reflection should take account of current technical and biological limitations and also of current uncertainties with regard to the meaning of genetic variance. However, ethicists should also not be afraid to look into the future. There was a general agreement that embryo testing will be increasingly preceded by comprehensive preconception screening, thus enabling smart combinations of genetic testing. LIMITATIONS, REASONS FOR CAUTION The group was composed of seven participants from four Western Europe countries. As willingness to participate in this study may be connected with expectations regarding the pace and direction of future developments, selection bias cannot be excluded. WIDER IMPLICATIONS OF THE FINDINGS The introduction of comprehensive screening techniques in embryo testing calls for further ethical reflection that is grounded in empirical work. Specifically, there is a need for studies querying the opinions of infertile couples undergoing IVF/PGS regarding the desirability of embryo screening beyond aneuploidy. STUDY FUNDING/COMPETING INTEREST(S) This research was supported by the CSG, Centre for Society and Life Sciences (project number: 70.1.074). The authors declare no conflict of interest.

Abstract
Preimplantation genetic diagnosis (PGD) has been considered as an alternative to prenatal diagnosis for prevention of genetic disorders while avoiding the subsequent termination of pregnancy. However, the limited amount of template DNA available in a single diploid cell used for PGD leads to number of problems including an increased incidence of detectable contamination; amplification failure and allele drop out. Due to their highly polymorphic and amplifiable characteristics, short tandem repeat (STR) analysis has been proposed as a mean to overcome these limitations. Heterozygosity of the applied STRs is of paramount importance in their informativity, and should therefore be studied in any certain population. Here, for the first time, we report on the heterozygosity analysis of five STR markers (D5S1408, D5S1417, D5S610, D5S629 and D5S637) flanking to SMA gene region, to examine their applicability in the PGD for SMA disease. We have also investigated other statistical features of these markers and found that all of the five studied STRs were informative and four meet the Hardy-Weinberg equilibrium for the studied population. Furthermore, our results propose that similar approaches can be used for the PGD of other single gene disorders.

Abstract
The scope of conditions for which preimplantation genetic diagnosis (PGD) is licensed has recently been expanded in the United Kingdom to include genetic predisposition to adult-onset cancer. This qualitative interview study explores reproductive decision making, knowledge of and attitudes to reproductive genetic testing (prenatal diagnosis and PGD) with 25 women aged 18-45 years who received a positive BRCA test in the United Kingdom before having children. In this cohort of younger women, BRCA testing was motivated by risk management decisions; for some, BRCA status has affected their later decisions about having children. The perceived severity of hereditary breast/ovarian cancer (HBOC) influences thoughts about passing on the mutation to children and willingness to consider reproductive genetic testing, but most participants do not believe HBOC is a condition for which pregnancy termination is justified. PGD is considered more acceptable and advantageous because it would prevent transmission to future generations, but women have concerns about selecting embryos and the fact that they and affected family members would not have been selected. Women would also be deterred by the need to undergo in vitro fertilisation (IVF) and ovarian stimulation for PGD. Awareness of reproductive testing options was very variable among the cohort. The findings highlight the complexities of reproductive decision making for young women who knowingly carry a BRCA mutation, and the dilemmas inherent to reproductive genetic testing when the condition being tested for also affects a prospective parent. Counselling and psychological support for BRCA-positive women and couples concerning reproductive options are strongly indicated.

Abstract
Prenatal diagnosis (PND) aims to provide accurate, rapid results as early in pregnancy as possible. Conventional PND involves sampling cells of foetal origin by chorionic villus sampling at 11-14th weeks of pregnancy or amniocentesis after 15th week. These are invasive procedures and have a small but significant rate of 0.5% to 1% for loss of pregnancy. An alternative to existing methods for conventional PND for couples at risk of transmitting a genetic disease to their child is preimplantation genetic diagnosis (PGD). PGD is a newly emerging form of a very early prenatal diagnosis. The technique combines assisted reproductive technology with molecular genetics and cytogenetics to allow the identification of abnormality in embryos prior to implantation. The diagnosis of genetic disease in human preimplantation embryos was pioneered in the late 1980s for testing of aneuploidy, single gene and X-linked disease, such as cystic fibrosis, haemophilia and chromosomal abnormalities. The PGD-related legal and ethical issues have been debated at many levels both nationally and internationally. The attitude towards PGD varies substantially not only in different parts of the world but also within the Europe, owing to scientific, cultural and religious differences. PGD has become widely practised throughout the world for various indications and can substantially decrease the eventual risks of passing a genetic undesired condition of the offspring. Nevertheless, its extension to some new and non-medical indications has raised ethical concerns, in particular its potential eugenic dimension.

Abstract
Peutz-Jeghers syndrome (PJS) is a hereditary disorder caused by LKB1 gene mutations, and is associated with considerable morbidity and decreased life expectancy. This study was conducted to assess the attitude of PJS patients towards family planning, prenatal diagnosis (PND) and pregnancy termination, and pre-implantation genetic diagnosis (PGD). In a cross-sectional study, 61 adult PJS patients were asked to complete a questionnaire concerning genetic testing, family planning, PND and PGD. The questionnaire was completed by 52 patients (85% response rate, 44% males) with a median age of 44 (range 18-74) years. A total of 37 (71%) respondents had undergone genetic testing. In all, 24 respondents (46%, 75% males) had children. A total of 15 (29%) respondents reported that their diagnosis of PJS had influenced their decisions regarding family planning, including 10 patients (19%, 9/10 females) who did not want to have children because of their disease. Termination of pregnancy after PND in case of a foetus with PJS was considered 'acceptable' for 15% of the respondents, whereas 52% considered PGD acceptable. In conclusion, the diagnosis of PJS influences the decisions regarding family planning in one third of PJS patients, especially in women. Most patients have a negative attitude towards pregnancy termination after PND, while PGD in case of PJS is judged more acceptable. These results emphasise the importance of discussing aspects regarding family planning with PJS patients, including PND and PGD.

Abstract
OBJECTIVE To provide an in-depth account of the experience of pre-implantation genetic diagnosis (PGD). METHOD Exploratory qualitative interview study. Participants were recruited from one major in vitro fertilization (IVF) clinic in Sydney, Australia. Data were collected through 14 in-depth interviews with women at different stages of PGD, utilized a thematic approach and facilitated by NVivo software. RESULTS Women reported using PGD as empowering and led them to feel in control of their reproductive futures. Health professionals who did not tell women about PGD were seen as a barrier to accessing treatment. The ability to select embryos free from the genetic condition (for which it was at risk) alleviated stress. Despite this, stress experienced with PGD was significant for women, and often related to past experiences of reproductive trauma and grief. The outcome of embryos was also the cause of stress for women. CONCLUSION Women undergoing PGD have a diverse range of reproductive and genetic histories, psychosocial circumstances and world views that all interact and impact their experience of PGD. Successful support and care of these women should address all of these factors and tailor the support provided for women using this physically and emotionally complex form of reproductive technology.

Abstract
BACKGROUND Preimplantation genetic diagnosis (PGD) has been proposed as an alternative to prenatal diagnosis (PND). This study compares the attitudes towards PGD of four groups of parents in Saudi Arabia: two groups at genetic risk for different conditions but with no experience of PGD procedures and two groups who had experience, either of PGD or of in vitro fertilisation (IVF) for infertility. METHODS One hundred and eighty four participants attending the King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Riyadh were interviewed using a semi-structured questionnaire: 49 had children affected by a haemoglobin disorder, 48 had children with non-syndromic deafness, 37 were attending the PGD service and 50 were attending IVF services for infertility. RESULTS Opinions in the two genetic groups were very similar: families were enthusiastic about PGD and relatively unconcerned about its technical limitations or the desirability of a confirmatory PND. The technical limitations of PGD and the moral status of embryos were of greatest concern to the PGD group. Waiting for the pregnancy result was the most commonly mentioned concern in the PGD and IVF groups. CONCLUSION PGD might be considered for a range of conditions in Saudi Arabia. However, it is not an easy option, and couples must be selected and counselled appropriately.

Abstract
BACKGROUND PGD has been described in previous cross-sectional and retrospective studies as a stressful experience. No prospective studies of the psychological impact of PGD are currently available. METHODS Using a prospective study design, validated measures exploring anxiety and depression were used to assess women using PGD prior to treatment, following embryo transfer, following the pregnancy test result and at 24 weeks of pregnancy. Maternal-fetal attachment was also assessed during pregnancy. RESULTS The prospective design revealed the cyclical pathway through PGD for many women, often comprising repeated cycles of ovarian stimulations and IVF and frozen embryo transfers. As predicted, there were significant fluctuations in women's anxiety scores, with increases observed following embryo transfer and pregnancy testing. Women's anxiety scores returned to baseline levels during pregnancy as assessed at 24 weeks gestation. Depression scores did not significantly fluctuate during PGD. Maternal-fetal attachment scores in this sample did not differ from the normative Australian data. CONCLUSIONS For some women, the PGD pathway is convoluted and requires multiple IVF cycles and embryo transfers to achieve pregnancy. A subset of women experience significant emotional burden during PGD treatment, and it is these women who require closer attention and support. In this sample, emotional adjustment in pregnancy following PGD appears to be sound.

Abstract
OBJECTIVE To illuminate and synthesize what is known about the underlying decision making processes surrounding couples' preimplantation genetic diagnosis (PGD) use or disuse and to formulate an initial conceptual framework that can guide future research and practice. METHODS This systematic review targeted empirical studies published in English from 1990 to 2008 that examined the decision making process of couples or individual partners that had used, were eligible for, or had contemplated PGD. Sixteen studies met the eligibility requirements. To provide a more comprehensive review, empirical studies that examined healthcare professionals' perceptions of couples' decision making surrounding PGD use and key publications from a variety of disciplines supplemented the analysis. RESULTS The conceptual framework formulated from the review demonstrates that couples' PGD decision making is composed of three iterative and dynamic dimensions: cognitive appraisals, emotional responses, and moral judgments. CONCLUSION Couples think critically about uncertain and probabilistic information, grapple with conflicting emotions, and incorporate moral perspectives into their decision making about whether or not to use PGD. PRACTICE IMPLICATIONS The quality of care and decisional support for couples who are contemplating PGD use can be improved by incorporating focused questions and discussion from each of the dimensions into counseling sessions.

Abstract
This article reports from a study exploring the social processes, meanings and institutions that frame and produce 'ethical problems' and clinical dilemmas for practitioners, scientists and others working in the specialty of preimplantation genetic diagnosis (PGD). A major topic in the data was that, in contrast to IVF, the aim of PGD is to transfer to the woman's womb only those embryos likely to be unaffected by serious genetic disorders; that is, to produce 'healthy babies'. Staff described the complex processes through which embryos in each treatment cycle must meet a double imperative: they must be judged viable by embryologists and 'unaffected' by geneticists. In this article, we focus on some of the ethical, social and occupational issues for staff ensuing from PGD's double imperative.

Abstract
PURPOSE Innovative applications of genetic testing have emerged within the field of assisted reproductive technology through preimplantation genetic diagnosis. As in all forms of genetic testing, adequate genetic counseling and informed consent are critical. Despite the growing recognition of the role of informed consent in genetic testing, there is little data available about how this process occurs in the setting of preimplantation genetic diagnosis. METHODS A cross-sectional study of in vitro fertilization clinics offering preimplantation genetic diagnosis in the United States was conducted to assess patient education and informed consent practices. Descriptive data were collected with a self-administered survey instrument. RESULTS More than half of the clinics offering preimplantation genetic diagnosis required genetic counseling before preimplantation genetic diagnosis (56%). Genetic counseling was typically performed by certified genetic counselors (84%). Less than half (37%) of the clinics required a separate informed consent process for genetic testing of embryonic cells. At a majority of those clinics requiring a separate informed consent for genetic testing (54%), informed consent for preimplantation genetic diagnosis and genetic testing took place as a single event before beginning in vitro fertilization procedures. CONCLUSIONS The results suggest that patient education and informed consent practices for preimplantation genetic diagnosis have yet to be standardized. These findings warrant the establishment of professional guidelines for patient education and informed consent specific to embryonic genetic testing.

Abstract
Preimplantation genetic diagnosis (PGD) was first reported as successful in humans in the early 1990s and nearly two decades later the psychological impact of PGD has not yet been clearly defined. As PGD requires the use of IVF, this paper provides a brief summary of literature related to the various psychological aspects of IVF followed by a review of the literature related to the psychological and broader psychosocial impact of PGD. The current literature includes attitudinal studies of couples for whom PGD may be beneficial and results suggest that those with traumatic reproductive and genetic histories are more likely to find PGD an acceptable treatment option. A small number of studies have used samples of women and couples who have used PGD. Due to a general lack of homogeneity in scope, method and results, these studies have not provided a uniform understanding of the PGD experience. Promisingly, however, two studies on parents of children born after PGD that explored parental stress show no differences between PGD, IVF and natural conception couples. The paper concludes that the missing link in the literature is a prospective study of PGD using validated psychological scales. Suggestions for future research are provided.

Abstract
Childhood DNA testing, prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are available for familial adenomatous polyposis (FAP). However, the use of PND and PGD is controversial. The purpose of this study was to investigate attitudes toward, and experiences with, childhood DNA testing, PND and PGD among members of families at high risk for FAP. In this nationwide, cross-sectional study, questionnaires were sent to individuals from families at high risk for FAP assessing attitudes toward and experiences with childhood testing, PND and PGD, as well as several sociodemographic, clinical and psychosocial variables. Of the individuals from FAP families invited to participate in the study, 525 members participated (response rate=64%). Most parents who had children who were minors (n=93) (82%) were satisfied with the DNA testing procedure. One-third of all individuals wanted DNA testing for their children before age 12. Forty percent of FAP patients indicated that the disease influenced their desire to have children. Only 15% considered termination of pregnancy for FAP acceptable. Approximately 30% of individuals with a FAP diagnosis and their partners considered PND and PGD as acceptable for themselves. A positive attitude was associated with higher levels of guilt and a positive attitude toward termination of pregnancy. Importantly, of those with FAP at childbearing age, 84% had had no previous information at all about either PND or PGD. Future efforts should be aimed at educating FAP family members about reproductive options, allowing them to make an informed choice about family planning. Routine discussion of all reproductive options with a medical specialist should be encouraged.

Abstract
The use of pre-implantation genetic diagnosis (PGD) for hereditary cancer is subject to on-going debate, particularly among professionals. This study evaluates the attitude towards PGD and attitude-associated characteristics of those concerned: family members with a hereditary cancer predisposition. Forty-eight Von Hippel-Lindau and 18 Li–Fraumeni Syndrome families were identified via the 9 family cancer clinics in the Netherlands. In total, 216 high risk family members and partners were approached, of whom 179 (83%) completed a self-report questionnaire. Of the high risk family members, 35% expressed a positive attitude towards PGD. Those with a current desire to have children were significantly more likely to have a positive attitude: 48% would consider the use of PGD. No other sociodemographic, medical or psychosocial variables were associated significantly with a positive attitude. The most frequently reported advantage of PGD is the avoidance of a possible pregnancy termination. Uncertainty about late effects was the most frequently reported disadvantage. These results indicate that approximately half of those contemplating a future pregnancy would consider the use of PGD. The actual uptake, however, is expected to be lower. There is no indication that psychosocial factors affect interest in PGD.

Abstract
Preimplantation genetic diagnosis is a form of very early prenatal diagnosis. The technique combines assisted reproductive technology with molecular genetics and cytogenetics to allow the identification of abnormalities in embryos prior to implantation. Since its introduction in 1990 this approach has been applied to an increasing number of single gene disorders, chromosomal rearrangements, and more recent indications such as aneuploidy screening and HLA matching. Since its inception the technology has attracted much attention: geneticists have expressed concerns about the robustness and validity of diagnosis based on single cell analysis, perinatologists were anxious about the effect of embryo biopsy on normal fetal development; and philosophers and ethicists have argued the cases for and against embryo selection. This article attempts to highlight the difficult choices and ethical challenges confronting patients and clinicians in an effort to balance the recognition of parental autonomy with the obligation of clinics to consider the welfare of any child born as a result of this treatment.

Abstract
Although morally acceptable in theory, preimplantation genetic diagnosis (PGD) for mitochondrial DNA (mtDNA) disorders raises several ethical questions in clinical practice. This paper discusses the major conditions for good clinical practice. Our starting point is that PGD for mtDNA mutations should as far as possible be embedded in a scientific research protocol. For every clinical application of PGD for mtDNA disorders, it is not only important to avoid a 'high risk of serious harm' to the future child, but also to consider to what extent it would be possible, desirable and proportional to try to reduce the health risks and minimize harm. The first issue we discuss is oocyte sampling, which may point out whether PGD is feasible for a specific couple. The second issue is whether one blastomere represents the genetic composition of the embryo as a whole -- and how this could (or should) be investigated. The third issue regards the cutoff points below which embryos are considered to be eligible for transfer. We scrutinize how to determine these cutoff points and how to use these cutoff points in clinical practice -- for example, when parents ask to take more or less risks. The fourth issue regards the number of cycles that can (or should) justifiably be carried out to find the best possible embryo. Fifth, we discuss whether follow-up studies should be conducted, particularly the genetic testing of children born after IVF/PGD. Finally, we offer the main information that is required to obtain a truly informed consent.

Abstract
OBJECTIVE The aim of the study was to assess the rate of acceptance of preimplantation genetic diagnosis (PGD) as an alternative to prenatal diagnosis in Lebanese women with previously affected children with homozygous beta-thalassemia. METHODS Women with a previously affected child attending a non governmentally funded thalassemia care center between 1 June 2005 and 31 May 2007 were offered a genetic counseling session. This was followed by administering a questionnaire through direct interview. RESULTS All 97 women approached accepted to participate in the study (100% response rate). Sixty eight per cent of women considered PGD a better alternative to prenatal diagnosis. The most important perceived advantage of PGD was the avoidance of termination of an affected pregnancy. CONCLUSIONS PGD is an acceptable alternative to conventional prenatal diagnosis in women at risk of conceiving a child affected with beta-thalassemia. This is particularly true in countries of the Middle-East where therapeutic abortions for fetal indications are prohibited by the law and religion.
