Assisted reproductive technology in the USA: is more regulation needed?

Klinefelter syndrome: etiology and clinical considerations in male infertility†

Klinefelter syndrome (KS) is the most prevalent chromosomal disorder occurring in males. It is defined by an additional X chromosome, 47,XXY, resulting from errors in chromosomal segregation during parental gametogenesis. A major phenotype is impaired reproductive function, in the form of low testosterone and infertility. This review comprehensively examines the genetic and physiological factors contributing to infertility in KS, in addition to emergent assisted reproductive technologies, and the unique ethical challenges KS patients face when seeking infertility treatment. The pathology underlying KS is increased susceptibility for meiotic errors during spermatogenesis, resulting in aneuploid or even polyploid gametes. Specific genetic elements potentiating this susceptibility include polymorphisms in checkpoint genes regulating chromosomal synapsis and segregation. Physiologically, the additional sex chromosome also alters testicular endocrinology and metabolism by dysregulating interstitial and Sertoli cell function, collectively impairing normal sperm development. Additionally, epigenetic modifications like aberrant DNA methylation are being increasingly implicated in these disruptions. We also discuss assisted reproductive approaches leveraged in infertility management for KS patients. Application of assisted reproductive approaches, along with deep comprehension of the meiotic and endocrine disturbances precipitated by supernumerary X chromosomes, shows promise in enabling biological parenthood for KS individuals. This will require continued multidisciplinary collaboration between experts with background of genetics, physiology, ethics, and clinical reproductive medicine.

A systematic review of assisted and third-party reproduction guidelines regarding management and care of donors

BACKGROUND

Gamete and embryo donors face complex challenges affecting their health and quality of life. Healthcare providers need access to well-structured, evidence-based, and needs-based guidance to care for gamete and embryo donors. Therefore, this systematic review aimed to synthesize current assisted and third-party reproduction guidelines regarding management and care of donors.

METHODS

The databases of ISI, PubMed, Scopus, and websites of organizations related to the assisted reproduction were searched using the keywords of "third party reproduction", "gamete donation", "embryo donation", "guidelines", "committee opinion", and "best practice", without time limit up to July 2023. All the clinical or ethical guidelines and best practice statements regarding management and care for gamete and embryo donors written in the English language were included in the study. Quality assessment was carried using AGREE II tool. Included documents were reviewed and extracted data were narratively synthesized.

RESULTS

In this systematic review 14 related documents were reviewed of which eight were guidelines, three were practice codes and three were committee opinions. Five documents were developed in the United States, three in Canada, two in the United Kingdom, one in Australia, and one in Australia and New Zealand. Also, two guidelines developed by the European Society of Human Reproduction and Embryology were found. Management and care provided for donors were classified into four categories including screening, counseling, information provision, and ethical considerations.

CONCLUSION

While the current guidelines include some recommendations regarding the management and care of gamete/embryo donors in screening, counseling, information provision, and ethical considerations, nevertheless some shortcomings need to be addressed including donors' psychosocial needs, long-term effects of donation, donors' follow-up cares, and legal and human rights aspects of donation. Therefore, it is needed to conduct robust and well-designed research studies to fill the knowledge gap about gamete and embryo donors' needs, to inform current practices by developing evidence-based guidelines.

Transfer of embryos with positive PGT-M results: Genetic Counselors' perspectives and ethical considerations

Increasing numbers of fertility patients use preimplantation genetic testing for monogenic conditions (PGT-M) during in vitro fertilization (IVF). While PGT-M is primarily used to avoid implanting embryos with a monogenic condition, patients can request to transfer an embryo with the monogenic condition (positive embryo transfer), especially in cases where an IVF cycle results in no unaffected embryos. Transferring embryos with known disease-causing variants raises ethical concerns. There is limited understanding about how stakeholders in the assisted reproductive technology (ART) field approach these issues. In this study, genetic counselors were sent a survey to gather insight into their views about transferring embryos with different monogenic conditions. N = 99 genetic counselors completed the survey, 22 of whom had experience with patients requesting or deciding to transfer an embryo with a monogenic condition (positive embryo transfer experience). Most participants, including those with positive embryo transfer experience, were supportive of positive embryo transfer, regardless of the genetic condition. While participating genetic counselors were largely supportive of all patient decisions, they reported increased moral uneasiness around transferring embryos with life-limiting monogenic conditions, such as Huntington's disease. Further investigation into the experiences of genetic counselors who have experienced positive embryo transfer requests in practice can help delineate the ethical questions that ART providers face in this context and clarify how genetic counselors can contribute to establishing guidelines in the ART field.

Cryostorage management of reproductive cells and tissues in ART: status, needs, opportunities and potential new challenges

Among the wide range of procedures performed by clinical embryologists, the cryopreservation of reproductive cells and tissues represents a fundamental task in the daily routine. Indeed, cryopreservation procedures can be considered a subspecialty of medically assisted reproductive technology (ART), having the same relevance as sperm injection or embryo biopsy for preimplantation genetic testing. However, although a great deal of care has been devoted to optimizing cryopreservation protocols, the same energy has only recently been spent on developing and implementing strategies for the safe and reliable storage and transport of reproductive specimens. Herein, we have summarized the content of the available guidelines, the risks, the needs and the future perspectives regarding the management of cryopreservation biorepositories used in ART.

Main topics in assisted reproductive market: A scoping review

BACKGROUND

Infertility affects around 12% of couples, and this proportion has been gradually increasing. In this context, the global assisted reproductive technologies (ART) market shows significant expansion, hovering around USD 26 billion in 2019 and is expected to reach USD 45 billion by 2025.

OBJECTIVES

We realized a scoping review of the ART market from academic publications, market reports, and specialized media news, to identify the main terms and characterize them into the main topics in the area.

DESIGN

We apply an LDA topic modeling process to identify the main terms, and clustered them into semantic synonymous topics. We extracted the patterns and information to these topics and purposed a factor/consequence correlation to them.

RESULTS

We found 2,232 academic papers and selected 632 to include in the automatic term detection. We also included 34 market reports and seven notices produced by specialized enterprises. Were identified 121 most relevant cited terms covering 7,806 citations. These terms were manually aggregated into 10 topics based on semantic similarity: neutral terms (37.2%), economic aspects (17.6%), in vitro fertilization (IVF) commodities & cross-border reproductive care (CBRC) (10.6%), geographic distribution (9.5%), social aspects (7%), regulation (6%), trends & concerns (3.9%), accessibility (3.4%), internet influence (2.9%), and fertility preservation for non-medical reasons (2%).

DISCUSSION

The analysis indicates a market with expressive complexity. Most terms were associated with more than one topic, indicating the synergism of this market's behavior. Only seven terms related to economic aspects, surrogacy and donation represent around 50% of the citations. Except for the topic formed by generic terms, the topic of the economic aspects was the most represented, reflecting macro perspectives such as a-la-carte standard of treatments, many clinics operating on a small/medium scale, and the recent formation of conglomerates. The IVF commodities & CBRC topic brings an overview of gametes pricing and transnational surrogacy, and its regulation. The topic of geographic distribution indicates that that the Asia-Pacific (APAC) market has the most significant growth potential in all fields. Despite the increase in supply and demand for infertility treatments and technological advances in recent decades, the success rate of IVF cycles remains at around 30%. Terms referring to research and development or technical improvement were not identified in a significant way in this review.

CONCLUSIONS

The formation of topics by semantic similarity proved to be an initial path for the elaboration of in-depth studies on the dynamics between several factors, for this, we present the panel classifying main terms into factors (demand, pent-up demand, or distributive) or ART market consequences. Through this approach, it was possible to observe that most of the works addresses economic aspects, regulation and geographic aspects and that topics related to research and improvement have not been addressed. In this way, we highlight the need to deepen the analysis of market elements that may be related to increased efficiency of IVF in the technical field.

Circulating miRNAs as a Tool for Early Diagnosis of Endometrial Cancer-Implications for the Fertility-Sparing Process: Clinical, Biological, and Legal Aspects

This review article explores the possibility of developing an integrated approach to the management of the different needs of endometrial cancer (EC) patients seeking to become pregnant. Life preservation of the woman, health preservation of the baby, a precocious and-as much as possible-minimally invasive characterization of the health and fertility parameters of the patient, together with the concerns regarding the obstetric, neonatal, and adult health risks of the children conceived via assisted reproductive techniques (ART) are all essential aspects of the problem to be taken into consideration, yet the possibility to harmonize such needs through a concerted and integrated approach is still very challenging. This review aims to illustrate the main features of EC and how it affects the normal physiology of pre-menopausal women. We also focus on the prospect of a miR-based, molecular evaluation of patient health status, including both EC early diagnosis and staging and, similarly, the receptivity of the woman, discussing the possible evaluation of both aspects using a single specific panel of circulating miRs in the patient, thus allowing a relatively fast, non-invasive testing with a significantly reduced margin of error. Finally, the ethical and legal/regulatory aspects of such innovative techniques require not only a risk-benefit analysis; respect for patient autonomy and equitable health care access allocation are fundamental issues as well.

Comparative metabolomic profiling of women undergoing in vitro fertilization procedures reveals potential infertility-related biomarkers in follicular fluid

Infertility is a worldwide concern, affecting one in six couples throughout their reproductive period. Therefore, enhancing the clinical tools available to identify the causes of infertility may save time, money, and emotional distress for the involved parties. This study aims to annotate potential biomarkers in follicular fluid that are negatively affecting pregnancy outcomes in women suffering infertility-related diseases such as endometriosis, tuboperitoneal factor, uterine factor, and unexplained infertility, using a metabolomics approach through high-resolution mass spectrometry. Follicular fluid samples collected from women who have the abovementioned diseases and managed to become pregnant after in vitro fertilization procedures [control group (CT)] were metabolically compared with those from women who suffer from the same diseases and could not get pregnant after the same treatment [infertile group (IF)]. Mass spectrometry analysis indicated 10 statistically relevant differential metabolites in the IF group, including phosphatidic acids, phosphatidylethanolamines, phosphatidylcholines, phosphatidylinositol, glucosylceramides, and 1-hydroxyvitamin D3 3-D-glucopyranoside. These metabolites are associated with cell signaling, cell proliferation, inflammation, oncogenesis, and apoptosis, and linked to infertility problems. Our results indicate that understanding the IF's metabolic profile may result in a faster and more assertive female infertility diagnosis, lowering the costs, and increasing the probability of a positive pregnancy outcome.

A comparison of assisted human reproduction (AHR) regulation in Ireland with other developed countries

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.

The need for regulation in the practice of human assisted reproduction in Mexico. An overview of the regulations in the rest of the world

BACKGROUND

The emergence of assisted reproductive technology (ART) in humans has been an important tool for the treatment of infertility. The number of treatments performed in Latin America has been increasing, and Mexico is the third country with the most assisted reproduction cycles performed in the region. However, Mexico lacks a national regulation for assisted reproduction. Therefore, it is necessary to implement regulations that allow for a safe clinical practice based on ethics which can be available to any social group.

MAIN BODY

The aim of this review was to examine the existing legislation that regulates human assisted reproduction practices in Mexico, but also to examine the legal analysis of the policies, laws, and regulations in effect in some countries in Latin America, North America, and Europe. For this, seven databases were consulted, and 34 articles from 2004 to 2021 referring to the practice of ART within the legal framework and the anthropological analysis that this entails were analyzed. Eight documents were also consulted such as the Mexican General Health Law of the Official Journal of the Federation (February 7, 1984) with its last published reform (DOF 01-06-2021). And three official agency websites were also consulted. No specific legislation was found for human assisted reproduction practices in Mexico; however, assisted reproduction clinics are ruled under some agreements implemented by national organizations such as the Mexican Association of Reproductive Medicine and, at the Latin America level, the Latin America Network of Assisted Reproduction (abbreviated REDLARA in Spanish); in addition, the practice of ART is considered, although not explicitly, in the General Health Law.

CONCLUSION

In Mexico, there is no legal regulation in charge of assisted reproduction practices, which is why there is an urgent need to establish human assisted reproduction laws without incurring discriminatory and unconstitutional acts, and at the same time, be in accordance with scientific advances. This will allow a considerable reduction in the violation of human rights.

Perception of Key Ethical Issues in Assisted Reproductive Technology (ART) by Providers and Clients in Nigeria

PURPOSE

In the past decade, developments in the field of Assisted Reproductive Technology (ART) have intensified the hopes and the desires of infertile people to overcome infertility, resulting in an increasing demand for such services worldwide. However, as developments in ART have evolved rapidly, so have ethical, social, and political controversies surrounding many aspects arisen. It is known that societal ethics is dependent on the values and culture of a given group. We sought to explore how practitioners and clients in Nigeria perceive some Key ethical issues surrounding ART.

MATERIALS AND METHODS

This was an explorative descriptive study involving in-depth interview of three ART providers and eight female ART clients, all domiciled in Southeastern Nigeria. Sampling was by purposive and snowballing techniques for providers and clients, respectively. Ethical approval was obtained from University of Ibadan/University College Hospital and University of Nigeria Teaching Hospital Research Ethics Committees. Responses were grouped into themes for ease of discussion.

RESULTS

Providers and clients were in support of sex selection for family balancing, and multiple embryo transfers. They also perceive that the health of the woman should be the factor considered and not biological age for service provision. However, views differed on marital status as an access factor. Participants were in support of legally binding regulations to guide practice.

CONCLUSION

A culturally sensitive national regulation is recommended to guide practice in this vital area of reproduction.

Offering preimplantation genetic testing for monogenic disorders (PGT-M) for conditions with reduced penetrance or variants of uncertain significance: Ethical insight from U.S. laboratory genetic counselors

Preimplantation genetic testing for monogenic disorders (PGT-M) was originally developed to identify embryos affected with serious childhood-onset disorders, but its use has recently broadened. Guidance on the use of PGT-M in the United States (U.S.) is currently limited, with no formal laws or guidelines established on its use. The goals of this study were to determine for which types of conditions U.S. laboratories currently do not offer PGT-M, to explore ethical considerations U.S. laboratory genetic counselors (GCs) take into consideration when deciding to accept or reject a PGT-M request, and to explore whether U.S. laboratory GCs believe PGT-M should be offered for conditions with reduced penetrance or for variants of uncertain significance (VUS). Qualitative analysis of semi-structured interviews with nine genetic counselors, from five different PGT-M laboratories, was conducted. Participants were required to be GCs working at a PGT-M laboratory in the U.S. and either actively counsel patients on PGT-M or determine a patient's eligibility for PGT-M. Two participants reported their separate laboratories have no limitations for allowable PGT-M testing, while the other seven participants representing three other laboratories reported having limitations. The main ethical consideration GCs reported considering when deciding to accept or reject a PGT-M request was patient autonomy, with a focus on the patient understanding risks of the testing. All participants reported believing PGT-M should be allowable for conditions with reduced penetrance and VUS, with all participants stating their respective laboratories allow for this currently. However, all participants reported a lack of sufficient guidelines and that having guidelines from a professional organization would be beneficial to their practice. In conclusion, lack of current guidelines in the United States has created discrepancies between PGT-M laboratories. PGT-M laboratory GCs support the use of PGT-M for conditions with reduced penetrance and VUS with informed consent. The need for guidelines is supported.

The highly complex issue of conscientious objection to abortion: can the recent European Court of Human Rights ruling Grimmark v. Sweden redefine the notions of care before freedom of conscience?

PURPOSE

The article aims to elaborate on two recent European Court of Human Rights (ECtHR) decisions which have rejected, on grounds of non-admissibility, the appeals by two Swedish midwives who refused to carry out abortion-related services, basing their refusal on conscientious objection, and to expound upon the legal and ethical underpinnings and core standards applied to the framing process of such a ECtHR decision.

MATERIALS AND METHODS

By drawing upon relevant recommendations from international institutions, the authors have aimed to assess how the ECtHR rationale could affect the balance between CO and patient rights; searches have been conducted up until December 2020.

RESULTS

In both decisions the European Court has asserted that the right to exercise conscientious objection must give way to the protection of the right to health of women seeking to have an abortion.

CONCLUSIONS

ECtHR judges concluded that the failure to provide for a right to conscientious objection does not constitute, in fact, a violation of the more general right to freedom of thought, conscience and religion, if provided for by a state law to protect the right to health. The legal ethical and social ramifications of such a decision are of enormous magnitude.

Theme trends and knowledge structure of assisted reproductive technology and birth defects: A quantitative and co-word analysis

AIM

The main purpose of our study is to determine the current research status of assisted reproductive technology (ART) and birth defects by means of co-word analysis, to explore the hot spots and weak points of current research, and to provide ideas and opinions for follow-up researchers.

METHODS

The PubMed database was used to investigate the knowledge structures of the applied words ART and birth defects. The published literature was searched until December 31, 2018. The extracted MeSH terms were quantified using the Bibliographic Item Co-Occurrence Matrix Builder and the high-frequency MeSH terms were determined. According to the MeSH term-source article matrix, hierarchical cluster analysis was performed using SPSS 19.0. The high frequency MeSH term co-occurrence matrix was constructed to support strategic diagram and social network analysis (SNA).

RESULTS

According to the search strategy, 1635 papers were included. Of all the extracted MeSH terms, 105 high frequency MeSH terms were identified and the hotspots were classified into nine categories. In the strategic diagram, research on the effects of prenatal diagnosis methods and ART on the development of offspring has been well developed. In contrast, research on reproductive ethics, epigenetics, and epidemiology is relatively immature, indicating the need for future research. For SNA results, the position status of each component is described by the center value.

CONCLUSIONS

By providing a quantitative bibliometric study, it can help with the overall command of the latest topic and guide researchers in their new projects.

Postmenopausal Pregnancy in the Era of Assisted Reproductive Technologies

Assisted reproductive technologies allow women to achieve pregnancy at ages beyond the limits of their natural reproductive lifespans. As women seek pregnancy later in life, physicians are challenged with balancing their professional autonomy against patient autonomy. Increased parental age increases risk to mother and fetus. Legal aspects of postmenopausal women desiring fertility services will vary by location. Ethically, the principles of beneficence, nonmaleficence, and justice become important factors in a physician's evaluation process. This article aims to highlight current guidelines for postmenopausal women desiring fertility services and address medical, legal, and ethical concerns that may arise when assessing these patients.

Regulatory responses to assisted reproductive technology: a comparative analysis of Spain and Israel

PURPOSE

The market of assisted reproductive technologies (ARTs) is rapidly evolving, raising growing ethical and social dilemmas. This paper compares the regulatory responses to technological and market developments in Israel and Spain, both intensive users of ART. We identify strengths and deficiencies in the regulation of ART in these two countries.

METHODS

We developed a conceptual framework to classify the factors affecting regulations and priority setting, and applied it using a Delphi survey combined with in-depth interviews. We selected two panels of experts from various fields, trying to simulate the bioethics committees of Israel and Spain.

RESULTS

ART is often wrongfully perceived as a solution to age-related infertility. Both panels embraced alternative solutions. The impact of private commercial interest on regulations is resulting in excessive practices such as the repeat of ineffective cycles and the push of sometimes unnecessary treatment add-ons. Our findings show experts dissatisfaction with the regulations of donor-eggs concerning reimbursement and registries in both countries.

CONCLUSIONS

The adequacy of ART to solve age-related infertility should be confronted with alternative approaches, with emphasis on the distribution of accurate information. The magnitude of ART markets, particularly the use of donor-eggs, should raise the need for additional societal debate and the reform of regulations. The impact factors analysis leads us to question the current regulatory framework, which could be improved by nominating a non-governmental statutory central regulatory agency in Israel and by reforming the Spanish agency.

Constructing queer mother-knowledge and negotiating medical authority in online lesbian pregnancy journals

Medical interactions around reproduction are increasingly extending beyond the physician's office and onto the Internet, where negotiation with medical authority occurs in complex and dynamic ways. Recently, scholars have noted the Internet's potential for creating spaces where women can dialogue with and reconstruct medical authority, yet this growing body of work is overwhelming heteronormative. This paper thus interrogates how lesbian women use the Internet to challenge, deploy, and rework medical authority around reproduction while navigating the transition to parenthood. I draw from 17 online journals authored by lesbian couples during the conception, pregnancy, and birth of their first child, each spanning between 18 months and 2 years, in order to understand how the transition process unfolds over time. I argue that lesbian couples engage with medical authority when seeking affirmation and normalisation yet discard and publicly reject the heteronormative assumptions that accompany reproductive medicine. Further, they chart a new process that I term 'constructing queer mother-knowledge', in which they critique and balance knowledges from institutionalised medicine, their own bodies, and their queer communities. With this new concept, I complicate understandings of lesbian mothers-to-be and their interactions with medical authority as they build subversive families.

A case report of embryo donation: ethical and clinical implications for psychologists

Third-party reproduction is a growing field, and an increasing body of literature considers the ethics of embryo donation. Due to the psychosocial complexities that generally accompany the donation and/or use of donor embryos, psychologists can play a pivotal role in these specialised fertility cases. While laws in the USA are in place to regulate the medical procedures involved in embryo donation, only unenforceable guidelines exist for psychologists specialising in fertility cases. The presentation of this case study aims to: (1) clarify the ethical concerns that fertility psychologists should consider in similar situations by assessing whether American Society of Reproductive Medicine (ASRM) and the American Psychological Association (APA) guidelines compete or complement one another within this case of embryo donation and (2) consider the interests, obligations and rights of all parties involved. Several principles, standards and guidelines that must be considered are described. Overall, the APA Ethics Code and the ASRM Guidelines appear to complement one another for most aspects of this case. Fertility psychologists should consider the clinical implications of the interests, rights and duties of all involved parties, including themselves.
