RESUMO

Preimplantation genetic testing (PGT) involves taking a biopsy of an early embryo created through in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). Genetic testing is performed on the biopsy, in order to select which embryo to transfer. PGT began as an experimental procedure in the 1990s, but is now an integral part of assisted human reproduction (AHR). PGT allows for embryo selection which can reduce the risk of transmission of inherited disease and may reduce the chance of implantation failure and pregnancy loss. This is a rapidly evolving area, which raises important ethical issues. This review article aims to give a brief history of PGT, an overview of the current evidence in PGT along with highlighting exciting areas of research to advance this technology.

RESUMO

Resumo: Este trabalho tem o objetivo de analisar as concepções de maternidade para mulheres inférteis de diferentes níveis socioeconômicos que estão em tratamento de reprodução assistida. Trata-se de um estudo qualitativo, descritivo, que utilizou como instrumento uma entrevista semiestruturada e contemplou temas como o significado de família, desejo/expectativas sobre filho e gestação e expectativas sobre a maternidade. Participaram da pesquisa 48 mulheres inférteis acima de 35 anos que usam tecnologias de reprodução assistida de alta complexidade em instituições privada e pública. Os dados foram tratados pela análise de conteúdo em que emergiram os temas: representações sociais da família; representações sociais da maternidade; expectativas com a gestação e os modelos maternos; e o filho imaginado. As participantes representaram a família de forma positiva, como um sistema de suporte, de fundação e origem de amor, configurando-a como um laço social. Por outro lado, as concepções de família com base na consanguinidade também estiveram presentes, representando a família pela perpetuação da espécie e pela importância do laço biológico. A maternidade foi marcada por significativa idealização, sendo vista como um papel gratificante e de realização da feminilidade. O peso da cobrança social para procriar também foi sentido como um dever a cumprir e que, na impossibilidade de se realizar, gera sentimentos de inferioridade, menos-valia, impotência e inadequação perante a sociedade, o que reforça o estigma da infertilidade. Tais resultados apontam a importância de reflexões sobre o papel da mulher na nossa cultura, visto que a maternidade é ainda utilizada como medida para o sucesso ou fracasso feminino. Faz-se necessário também refletir sobre a possibilidade da maior inserção do trabalho psicológico na reprodução assistida, visto a carga emocional e social envolvidas nesse processo.


Abstract: This study aimed to analyze the conceptions of motherhood for infertile women from different socioeconomic levels who are undergoing assisted reproduction treatment. This is a qualitative and descriptive study that used a semi-structured interview as an instrument and included topics such as the meaning of family and desires/expectations about the child, pregnancy, and motherhood. A total of 48 infertile women over 35 years of ages using high-complexity assisted reproductive technologies in private and public institutions participated in this research. The data were treated by content analysis in which the following themes emerged: family social representations; social representations of motherhood; expectations with pregnancy and maternal models; and the imagined son. Participants represented the family in a positive way as a support system and the foundation and origin of love, embracing the family as a social bond. On the other hand, the family concepts based on inbreeding were also present, representing the family by perpetuation of the species and the importance of biological bonds. Motherhood was marked by significant idealization, being seen as a gratifying role and the fulfillment of femininity. The weight of the social demand to procreate was also felt as a duty to be fulfilled that, in the impossibility of carrying it out, generates feelings of inferiority, worthlessness, impotence, and inadequacy toward society, which reinforce the stigma of infertility. Results point to the necessary reflections on the role of women and our culture since Motherhood is still used as a measure of female success or failure. They also point to a reflection on the possibility of greater inclusion of psychological work in assisted reproduction given the emotional and social burden involved in this process.


Resumen: Este estudio tuvo como objetivo analizar las concepciones de maternidad de mujeres infértiles, de diferentes niveles socioeconómicos, que se encuentran en tratamiento de reproducción asistida. Se trata de un estudio cualitativo, descriptivo, que utilizó como instrumento una entrevista semiestructurada e incluyó temas como el sentido de la familia, deseos/expectativas sobre el hijo y el embarazo y expectativas sobre la maternidad. Participaron en la investigación un total de 48 mujeres infértiles, mayores de 35 años, usuarias de tecnologías de reproducción asistida de alta complejidad en instituciones públicas y privadas. Los datos se sometieron a análisis de contenido del cual surgieron los temas: representaciones sociales familiares; representaciones sociales de la maternidad; expectativas con el embarazo y modelos maternos; hijo imaginado. Las participantes representaron a la familia de manera positiva, como sistema de apoyo, fundamento y origen del amor, configurándola como vínculo social. Por otro lado, también estuvieron presentes las concepciones familiares basadas en la consanguinidad, representando a la familia para la perpetuación de la especie y la importancia del vínculo biológico. La maternidad estuvo marcada por una importante idealización, vista como un rol gratificante y de realización de la feminidad. También se sintió el peso de la demanda social de procrear como un deber que cumplir y que, ante la imposibilidad de realizarlo, genera sentimientos de inferioridad, desvalorización, impotencia e inadecuación en la sociedad, lo que refuerza el estigma de la infertilidad. Por tanto, son necesarias reflexiones sobre el papel de la mujer en nuestra cultura, ya que la maternidad se sigue utilizando como medida del éxito o fracaso femenino. También se reflexiona sobre la posibilidad de una mayor inclusión del trabajo psicológico en la reproducción asistida dada la carga emocional y social que implica este proceso.

RESUMO

OBJECTIVES: Assisted human reproduction (AHR) is a complex process of clinical, laboratory, and organizational activities that involve risk and safety. The regulation of the Canadian fertility industry is a mix of federal and provincial/territorial responsibility. Oversight of care is fragmented as patients, donors, and surrogates may each live in different jurisdictions. The Canadian Medical Protective Association (CMPA) undertook a retrospective analysis of CMPA medico-legal data to identify the contributing factors to medico-legal risks for Canadian physicians providing AHR services. METHODS: Experienced CMPA medical analysts, reviewed information from closed cases. A previously reported medical coding methodology was applied to a 5-year retrospective descriptive analysis of CMPA cases closed between 2015 and 2019, involving physicians caring for patients with infertility seeking AHR. Class action legal cases were excluded. All contributing factors were analyzed using the CMPA Contributing Factor Framework.1 Cases were de-identified and reported at the aggregate level for analysis to ensure confidentiality for both patients and health care providers. RESULTS: There were 860 gynaecology cases with comprehensive information and peer expert review. Of these, 43 cases involved patients seeking AHR. Due to the small sample size, the results presented are for descriptive purposes only. AHR cases had an unfavourable outcome for the physician in 29 cases. Diagnostic error was noted in 10 cases. The most common patient allegations were related to a breakdown in communication. Peer experts were critical of patient care in 34 cases. These were divided among provider, team, and system factors. CONCLUSIONS: Diagnostic error was the most common clinical concern. Deficient clinical decision-making and communication breakdown with the patient contributed to these errors. Enhanced clinical decision-making, through heightened situational awareness, strengthened diagnostic test follow-up, and improved communication with the health care team may reduce medico-legal complaints related to AHR and improve patient safety.

RESUMO

OBJECTIVE: The aim: To study the current regulation on egg donation in Ukraine as one of the most attractive destinations for reproductive tourism, establish the current loopholes in the legal framework to be addressed when amending Ukrainian legal rules. PATIENTS AND METHODS: Materials and methods: The article is based on studying international and regional legal acts, jurisprudence of European Court of Human rights, pieces of national Ukrainian legislation, law drafts submitted to Ukrainian parliament and legal doctrine. The methodology of the article includes dialectical, comparative method and the method of systematic and structural analysis. CONCLUSION: Conclusions: Existing legal framework in Ukraine has some serious lacunas that can result in violation of rights and interests of donors and of the children. Firstly, the state does not keep the unique state register of donors. Secondly, there are no rules on compensation for egg donor. Lastly, the current Ukrainian legislation does not contain provisions ensuring protection of the child`s right to know about one`s genetic origin, and thus to obtain the identifying infor-mation about the donor. All these issues should be addressed in order to establish a fair balance between the rights and the interests of donors, recipients, the child and the society.

RESUMO

Brain abscesses are a possible complication of bacterial sepsis or central nervous system infection but are uncommon in the neonatal period. Gram-negative organisms often cause them, but Serratia marcescens is an unusual cause of sepsis and meningitis in this age group. This pathogen is opportunistic and frequently responsible for nosocomial infections. Despite the existing antibiotics and modern radiological tools, mortality and morbidity remain significant in this group of patients. We report an unusual unilocular brain abscess in a preterm neonate caused by Serratia marcescens. The infection had an intrauterine onset. The pregnancy was achieved through assisted human reproduction techniques. It was a high-risk pregnancy, with pregnancy-induced hypertension, imminent abortion, and required prolonged hospitalization of the pregnant woman with multiple vaginal examinations. The infant was treated with multiple antibiotic cures and percutaneous drainage of the brain abscess associated with local antibiotic treatment. Despite treatment, evolution was unfavorable, complicated by fungal sepsis (Candida parapsilosis) and multiple organ dysfunction syndrome.

RESUMO

The success rate for the evaluation of the results of techniques of Assisted Human Reproduction implies the occurrence of pregnancy with a live, healthy child. There are reports of the association between chemical and unhealthy environmental air conditions (bacteria, dust, particulates and volatile compounds) and reducing the success rate of embryo production and the occurrence of pregnancy. This paper reviews available information about the interference of biochemical, environmental and microbiological changes with the success of the assisted reproductive technique.

RESUMO

Assisted Human Reproduction (AHR) treatment is unregulated in Ireland, although it is practised there. Within Europe, Ireland is one of the only European countries without any form of AHR-specific regulation. This study aims to investigate the experiences and viewpoints of Irish women undergoing AHR treatments and establish if the lack of legislation is affecting these experiences. A quantitative survey was carried out on women undergoing AHR treatment in Irish clinics. Patients highlighted a lack of information in terms of end-to-end care and poor information around treatments and success rates. Key issues highlighted included unanticipated high treatment costs and add-on treatment costs, lack of financial support from the government, no redress process in the event of dissatisfaction, and generally an overall feeling of a lack of support both from the AHR clinics and the Irish government. This study offers a real-time view of the Irish AHR system from the patient's experience of AHR and under the lens of the lack of a legislative system. In early 2022, the Irish government announced that it would adopt its bill around AHR treatment and that subsidies for AHR treatment are to come into effect, which will alleviate some financial pressures on patients. Further studies of the legislation carried out post implementation will provide more information about the impact of having a legislated AHR process on the patients.

RESUMO

The use of assisted human reproduction (AHR) represents a meaningful and important life event for lesbians wishing to create biologically related families. Despite increasing numbers of lesbians utilizing AHR services, barriers to access persist. This qualitative study investigated the experiences of lesbians and their interactions with reproductive services in Ontario, Canada, where limited public funding is available for all AHR patients and where the lesbian, gay, bisexual, transgender, and queer (LGBTQ) community makes up to 30% of clientele. Eleven semi-structured interviews were conducted, and findings revealed a wide range of experiences. Lesbian patients expressed a desire for more support from their care providers in navigating a complex and costly medical journey through a system largely designed for the needs of heterosexual patients. Additionally, private fertility clinics, as the environment for accessing publicly funded services, were felt to contribute pressure to pay out-of-pocket for add-on medical procedures. To improve the quality of care, participants recommended providing more high-level information on the medical journey and taking an individual approach with lesbian patients, in particular, assuming a patient has sufficient fertility until proven otherwise.

RESUMO

BACKGROUND: Assisted human reproduction (AHR) treatment is not regulated in Ireland although it has been practiced since 1987. Thus, Ireland is one of the only European countries without any form of AHR specific regulation. This literature review research aimed to provide a comprehensive and comparative overview of AHR regulation and any associated literature to compare Ireland and other developed countries. METHODS: Systematic searches were conducted in several databases (Google Scholar, Web of Science, MEDLINE, SCOPUS and official government websites) utilising search strings in relation to AHR legislation for each country under review. A final review of 155 research articles were eligible after screening related to legislation in each country for inclusion. The findings were synthesised and summarised by legislation in each country. RESULTS: Different countries offer different levels of ART and IVF provision and services in terms of the type of services allowed, financial support, age, sex and eligibility of recipients. The UK's oversight legislation combined with the Netherlands financial legislation section provides as being most effective hybrid model of best practice for adoption in Ireland. CONCLUSIONS: This research concluded that there is no AHR legislation in any country that can be described as all-encompassing in terms of the services allowed, financial support and age of recipients. It was concluded that significant changes need to be made to the Irish draft legislation which is in limbo with the government for the last 3 years in order to meet Irish patient needs.


Ireland is one of the only European countries without any form of assisted human reproduction specific regulation. This research aimed to review of assisted human reproduction regulations to compare Ireland with other developed countries. There is no assisted reproduction legislation in any country that can be described as perfect. The UK's legislation combined with the Netherlands financial legislation section is concluded as being most effective hybrid model of best practice for adoption in Ireland. It was concluded that significant changes need to be made to the Irish draft legislation which is in limbo with the government for the last 3 years.

RESUMO

The object of this article is to contribute to the conceptual development of the procreational will, as an element that legitimises the medical acts of the assisted human reproduction techniques and that determines the resulting parenthood. The research problem refers to the disparity that is observed in Spanish and Catalan legislation between heterologous assisted reproduction and posthumous assisted reproduction: While in the first case informed consent is enough for the purpose of parenthood, in the second case the concurrence of genetic data is also required. The same scheme is presented in Argentina based on the projected regulation on posthumous reproduction. The hypothesis is that this problem has a bioethical reason, consisting in the distinction between the static dimension and the dynamic dimension of the procreative will, and in the requirement to genetic data in the absence of the latter.(AU)


El objeto del presente artículo es contribuir al desarrollo conceptual de la voluntad procreacional, en tanto elemento que legitima los actos médicos propios de las técnicas de reproducción humana asistida y que determina la filiación resultante. El problema de investigación refiere a la disparidad que se advierte tanto en la legislación española como en la catalana entre la reproducción asistida heteróloga y la reproducción asistida post mortem: Mientras en el primercaso el consentimiento informado es suficiente a los términos de la filiación, en el segundo supuesto se exige también la concurrencia del dato genético. El mismo esquema se presenta en Argentina a partir de la normativa proyectada sobre reproducción postmortem. La hipótesis sostenida es que ello posee una razón bioética suficiente, consistente en la distinción entre la dimensión estática y la dimensión dinámica de la voluntad procreacional, y en el recurso al elemento genético ante la ausencia anticipadade la segunda.(AU)


L'objecte del present article és contribuir al desenvolupament conceptual de la voluntat procreacional, en tant element que legitima els actes mèdics propis de les tècniques de reproducció humana assistida i que determina la filiació resultant. El problema de recerca refereix a la disparitat que s'adverteix tant en la legislació espanyola com en la catalana entre la reproducció assistida heteròloga i la reproducció assistida post mortem: Mentre en el primer cas el consentiment informat és suficient als termes de la filiació, en el segon supòsit s'exigeix també la concurrència de la dada genètica. El mateix esquema es presenta a l'Argentina a partir de la normativa projectada sobre reproducció post mortem. La hipòtesi sostinguda és que això posseeix una raó bioètica suficient, consistent en la distinció entre la dimensió estàtica i la dimensió dinàmica de la voluntat procreacional, i en el recurs a l'element genètic davant l'absència anticipada de la segona.(AU)

RESUMO

Resumen Las tecnologías de fertilización in vitro involucran una articulación tensa y contradictoria de sentidos hegemónicos establecidos en sistemas de creencias y normas respecto de la reproducción, la herencia genética, el parentesco, las identidades, las sexualidades, la naturaleza, lo sagrado, los cuerpos y el control y producción de la vida. A partir de experiencias etnográficas provenientes de entrevistas en profundidad realizadas entre los años 2007 y 2010 y entre 2017 y 2021 a trabajadoras en agencias de gestación por sustitución en Estados Unidos, profesionales vinculadas con los procedimientos en clínicas de fertilidad en Argentina y usuarios/as que acudieron a estas prácticas, este trabajo analiza las diferentes dimensiones y componentes que intervienen en los procedimientos de fertilización asistida: cuando las prácticas movilizan actores "aliados" al proyecto de paternidad y maternidad, las relaciones de poder y subalternidad resultan invisibilizadas en las transacciones. De forma simultánea, estas resultan imprescindibles para la producción material de las "parentalidades híbridas" en las que contextos particulares brindan interpretaciones y sensibilidades "situadas" en la trayectoria histórico-política argentina.


Abstract Biomedicine has built its object of study and intervention from a long and continuous process of desacralization, fragmentation, and progressive dissolution of the body as a monolithic entity in material and symbolic terms. Technological interventions provided possibilities for bodies, identities, and lives to be constructed, recombined, and designed by mobilizing molecular entities, which can be perceived as biofragments, with intervention practices. Consequently, in vitro fertilization technologies imply a tense and contradictory articulation of hegemonic meanings based on belief systems and norms about reproduction, genetic inheritance, kinship, identities, sexualities, nature, sanctity, bodies, and control and production of life. From ethnographic experiences in the area of assisted fertilization, this article analyzes the different dimensions and components that intervene in these procedures: when practices mobilize actors "allied" to the paternity and maternity project, the power and subalternity relations are made invisible in transactions. At the same time, these are essential for the material production of "hybrid parenthoods" in which particular contexts provide interpretations and sensibilities "situated" in the Argentine historical-political trajectory.

RESUMO

The Catholic perspective rejects assisted human reproduction techniques, but the morality of artificial insemination (AI) is open for discussion. This article aims to analyze the morality of AI from a new angle, namely whether these interventions exclude all possibility of damaging the human embryo and the offspring's health. The scientific evidence about the children's health who are born through AI allows us to affirm that the procedures do not comply with the principle of damage exclusion: AI does not exclude all possibility of damaging the embryo and impacting the health and exposure to disease of the offspring born through these techniques.

RESUMO

We argue that increased risk for a variety of diseases in ART children has been consistently reaffirmed by different methods and in diverse populations, providing a methodological critique of recent sibling studies, which hold great potential for studying the risks of ART. A recent within-family analysis using a national population register holds a distinct size advantage over previous studies, and suggested that apparent risks to offspring may be attributable to birth order. However, limitations of the design may have resulted in an erroneous conclusion. We discuss the advantages of a frequently neglected sibling study design, which compares siblings born of surrogate motherhood. While uncertainty remains, the evidence points to elevated risk for ART offspring. It may therefore be prudent to call for an extension of preventive and precautionary decisions to the entire population, and to change informed consent to incorporate the long-term health consequences of fertility treatments.

RESUMO

INTRODUCTION: Pregnancies resulting from assisted reproductive technologies (ART) have been documented to have a higher risk of adverse effects. OBJECTIVE: To provide evidence on obstetric and perinatal complications associated with conceptions by ART versus spontaneous pregnancies. METHOD: Comprehensive review of original articles published between 2010 and 2018 addressing the more common obstetric and perinatal complications in pregnancies resulting from in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), in comparison with spontaneous conceptions. RESULTS: Thirty-seven original articles, which reported on 26 cohort studies and 11 case-control trials, were included. IVF and ICSI conceptions were associated with a larger number of obstetric and perinatal complications such as low birth weight, prematurity, low weight for gestational age, admission to the neonatal intensive care unit, congenital malformations, C-sectionand premature rupture of membranes, among others. CONCLUSIONS: Pregnancies by ART are associated with an increased risk of obstetric and perinatal complications in comparison with spontaneous conceptions. Further research is needed to determine which aspects result in higher risk.


INTRODUCCIÓN: Se ha documentado que los embarazos por técnicas de reproducción asistida (TRA) presentan mayor riesgo de efectos adversos. OBJETIVO: Proporcionar evidencia actualizada de las complicaciones obstétricas y perinatales asociadas con concepciones mediante TRA versus embarazos espontáneos. MÉTODO: Revisión de artículos originales publicados entre 2010 y 2018, que abordan complicaciones obstétricas y perinatales de mayor frecuencia en embarazos por fertilización in vitro (FIV) e inyección intracitoplasmática de espermatozoides (ICSI) comparados con concepciones espontáneas. RESULTADOS: Se incluyeron 37 artículos originales, 26 de cohorte y 11 de casos y controles. Las concepciones por FIV e ICSI se asociaron con más complicaciones obstétricas y perinatales como bajo peso al nacimiento, prematuridad, menor peso para la edad gestacional, ingreso a la unidad de cuidados intensivos neonatales, malformaciones congénitas, cesárea, ruptura prematura de membranas, entre otras. ­. CONCLUSIONES: Las concepciones por TRA se asocian con mayor riesgo de complicaciones obstétricas y perinatales en comparación con las espontáneas. Es necesario realizar estudios adicionales que determinen qué aspectos derivan en mayor riesgo.

RESUMO

OBJECTIVE: This paper looked into the findings of a survey on the ethical and emotional aspects encircling the fate of surplus embryos in Assisted Human Reproduction (AHR). METHODS: Five staff members of a fertility clinic in the Brazilian State of São Paulo answered a semi-structured qualitative interview. RESULTS: The answers alluded to the different meanings assigned to embryos by medical staff (genetic material) and couples undergoing fertility treatment (potential child). The meaning couples assigned to their embryos, along with inherent uncertainty and distress, affected the choice of what would be done to surplus embryos. CONCLUSION: Psychological support may be helpful to two key groups present in assisted human reproduction: clinic staff, for support in their interactions with couples; and couples in need of support and awareness on surplus embryo donation.

RESUMO

Although numerous articles have shown intracytoplasmic sperm injection and in vitro fertilization to be correlated with increased risk of disease, a few works have been published on the risks associated with artificial insemination. Meanwhile, questions about the possible causes underlying these correlations have remained in the background. The main objective of this work is not to review the risks associated with artificial insemination, but rather to describe how developmental processes may be affected by these techniques. Thus, we offer a theoretical framework for understanding the possible causes that underlie the correlation between low-complexity or milder techniques and offspring health outcomes.

RESUMO

Commercial gamete donation in Canada is prohibited by the Assisted Human Reproduction Act. However, the Act permits gamete recipients to reimburse donors for donation-related expenses. Until recently, the types of expenses that were eligible and the process for reimbursing donors were not specified. In 2016, Health Canada announced its intent to develop regulations that would regulate gamete donor reimbursement; it released the proposed policy in 2017. As a result of consultations with Canadian lawmakers, physicians, and patients, debates surrounding commercial gamete donation are being revisited. Considering the ethical implications of gamete donation payment arrangements, a patient-centred care framework is useful going forward in the regulation of this practice. Patient-centred values of communication, respecting relational autonomy, and respecting patient interests should guide decisions regarding regulation of gamete donation arrangements in Canada.

RESUMO

This paper reports the case of a patient who sought assisted reproductive technology (ART) treatment and was referred to pre-implantation genetic diagnosis (PGD) on account of a chromosomal translocation presented with secondary infertility. The patient underwent a highly complex ART treatment and had 14 metaphase II oocytes collected on the day of follicular aspiration. The embryos were taken to extended culture and five were biopsied and vitrified. The embryo genetic report showed aneuploidy in four of the blastocysts, while the other resulted in 46, XX. In conclusion, chromosome translocations involving the X chromosome might result in the deregulation of gene expression and defective ovarian formation. Therefore, the genes present in the X chromosome are believed to be essential in normal ovarian function.

RESUMO

Current law in Victoria, Australia requires that all prospective assisted reproduction patients provide a criminal background check and child protection order check prior to being eligible for treatment. These presumptions against treatment stipulated in the Assisted Reproductive Treatment Act ( http://www.legislation.vic.gov.au/domino/web_notes/ldms/pubstatbook.nsf/f932b66241ecf1b7ca256e92000e23be/3ADFC9FBA2C0F526CA25751C0020E494/$FILE/08-076a.pdf , 2008) are discriminatory against all people that are infertile. Requiring assistance in founding a family says nothing about whether someone will be a minimally decent parent to their (future) child. The most plausible justifications for this differential treatment of family builders that require assistance are unsound. The wellbeing of the resulting child is something that the prospective patient(s) should be presumed to have at heart, as this is the default assumption with other kinds of family builders that do not require assistance. That assisted reproduction treatment is publicly funded does not mean that the state is thereby justified in putting moral conditions on access to treatment. As we should not accept discriminatory laws, especially about practices that are of fundamental importance to the lives of citizens, the presumptions against treatment stipulated in ARTA should be eradicated.
