IVF embryos in the bin, embryo-like structures in the spotlight.

Embryo-like structures (ELS) are intended for the study of embryonic development without the use of human supernumerary embryos. Scientists working in countries that do not allow research on embryos hope that these structures will replace natural embryos. The interest in ELS is largely based on two misconceptions: the belief that there is a shortage of research embryos and the belief that research on ELS will make research on natural embryos redundant. This paper argues that research efforts should be refocused on natural embryos.

Against age limits for men in reproductive care.

Almost all countries and fertility clinics impose age limits on women who want to become pregnant through Assisted Reproductive Technologies (ART). Age limits for aspiring fathers, however, are much less common and remain a topic of debate. This article departs from the principle of reproductive autonomy and a conditional positive right to receive ART, and asks whether there are convincing arguments to also impose age limits on aspiring fathers. After considering three consequentialist approaches to justifying age limits for aspiring fathers, we take in a concrete normative stance by concluding that those are not strong enough to justify such cut-offs. We reinforce our position by drawing a comparison between the case of a 39-year-old woman who wants to become a single mother via a sperm donor on the one hand, and on the other hand the same woman who wants to have a child with a 64-year-old man who she loves and who is willing to care for the child as long as he is able to. We conclude that, as long as appropriate precautions are taken to protect the welfare of the future child, couples who want to receive fertility treatment should never be limited on the basis of the age of the (male) partner. An absence of age limits for men would respect the reproductive autonomy of both the man and the woman.

Navigating conflicts of reproductive rights: Unbundling parenthood and balancing competing interests.

Advances in assisted reproductive technologies can give rise to several ethical challenges. One of these challenges occurs when the reproductive desires of two individuals become incompatible and conflict. To address such conflicts, it is important to unbundle different aspects of (non)parenthood and to recognize the corresponding reproductive rights. This article starts on the premise that the six reproductive rights-the right (not) to be a gestational, genetic, and social parent-are negative rights that do not entail a right to assistance. Since terminating or continuing a pregnancy is a form of assistance, the right (not) to be a gestational parent should enjoy primacy in conflicts. However, while refusing assistance may hinder the reproductive project of another person, "prior assistance" does not entitle someone to violate a reproductive right. Therefore, our analysis provides reasons to argue that someone has a right to unilaterally use cryopreserved embryos or continue the development of an entity in an extracorporeal gestative environment (i.e., ectogestation). Although this could lead to a violation of the right not to be a genetic parent, it does not necessarily entail a violation of the right not to be a social parent.

Overview of the current situation of embryo donation in Belgian fertility centers.

OBJECTIVES: The aim of this study is to survey the current situation in Belgium regarding embryo donation (ED) practices and to explore the potential reasons for not offering this treatment option. STUDY DESIGN: A questionnaire was sent to all fertility centers in Belgium that are allowed to perform IVF regarding whether or not they perform ED for third parties, their overall experience with ED and the possible reasons for not doing it. The questionnaire was divided into three different sections, depending on whether the center currently performs ED for third parties, has never performed it or once performed it but no longer does. All respondents were anonymized. RESULTS: The questionnaire was returned by 16 out of 18 centers. Only three out of 16 centers currently perform ED. All these centers require additional actions before ED can be performed. Sometimes ED is not performed although it was indicated in the contract; the most important reasons are the need for additional investigations, the administrative obstacles and the non-eligibility of the embryos. Between 2017 and 2021, few ED were performed in these centers (n = 2, 38 and 6). Eight out of 16 centers previously offered ED but ceased. In two centers, patients who want to donate their supernumerary embryos are referred for treatment to a center where ED is performed, but none of these centers transfer embryos to a center performing ED. The main reasons for discontinuing ED were the additional investigations required and the unprofitable investment in time and personnel. Five out of 16 centers never offered ED. At one center, patients who still indicate ED for their supernumerary embryos are referred to a center performing ED. The reduction of the administrative burden and avoiding additional testing are the most indicated measures that could facilitate the introduction of an ED program. CONCLUSIONS: Embryo donation, although legally allowed, is currently hardly performed in Belgium. The reasons for this are mainly associated to additional mandatory post-hoc testing and the extra administrative burden which is not financially covered. Poor transparency and communication between Belgian centers may be an additional factor explaining the country's low embryo donation rate.

Psychosocial outcomes of children born via embryo donation.

STUDY QUESTION: What are parents' perceptions of their relationships with and the psychosocial adjustments of their children who are born via embryo donation? SUMMARY ANSWER: Families created through embryo donation have well-adjusted parent-child relationships and reassuring child psychosocial outcomes. WHAT IS KNOWN ALREADY: Embryo donation is an effective and growing form of third-party reproduction, but there is limited research in this field. Prior studies suggest that families created through gamete donation function well regarding parent-child relationship quality and child behavioral and socioemotional adjustment. STUDY DESIGN, SIZE, DURATION: This is a cross-sectional survey study with 187 total participants. PARTICIPANTS/MATERIALS, SETTING, METHODS: Parents of children born via embryo donation were recruited nationally by contacting all embryo donation programs registered with the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) as well as medically directed embryo donation or 'embryo adoption' centers. Participants completed three online Qualtrics questionnaires. The first was a survey including 33 questions on demographics, the procurement process, and self-reported obstetric outcomes. Participants also completed two standardized measures assessing children's behavior and parents' adjustment to parenthood: the Strengths and Difficulties Questionnaire (SDQ) and the Parental Acceptance-Rejection Questionnaire (PARQ). Scoring of the SDQ and PARQ was totaled and compared to standardized values (SDQ) or previously published results on other forms of gamete donation (PARQ), such as oocyte donation and sperm donation. MAIN RESULTS AND THE ROLE OF CHANCE: On the SDQ (n = 46), the average total difficulties scores by age were: 8.2 ± 0.98 for ages 2-4, 7.6 ± 0.93 for ages 5-10, and 3.5 ± 0.77 for ages 11-17; this is compared to the normal reported range of 0-13, which indicates that clinically significant psychosocial problems are unlikely. Across all ages and individual categories (emotional symptoms, conduct problem, hyperactivity, peer problem, prosocial), scores on the SDQ were within the normal ranges. The average PARQ score (n = 70) for all respondents was 27.5 ± 1.18 (range: 24-96), suggesting perceived parental acceptance. LIMITATIONS, REASONS FOR CAUTION: Because this study was cross-sectional, it could not capture familial relationships over time. This survey-based study design allows for potential selection bias (parents of well-adjusted children may be more likely to participate). Additionally, the overall sample size is relatively small; however, it remains one of the largest published to date. Another significant limitation to this study is the lack of generalizability: most participants were recruited from private, faith-based, embryo donation programs who are demographically similar. WIDER IMPLICATIONS OF THE FINDINGS: Though embryo donation is an established form of third-party reproduction, it is significantly less robustly studied compared to other forms of gamete donation (oocyte or sperm donation). This study provides a larger data set with a more expanded age range of children compared to the limited number of previously published studies. Furthermore, these findings indicate a high parental disclosure rate with respect to the use of embryo donation which contrasts previous findings. STUDY FUNDING/COMPETING INTEREST(S): No external funding source was utilized for the completion of this study. No conflicts are disclosed. TRIAL REGISTRATION NUMBER: N/A.

Should a gamete bank verify the non-medical information provided by a donor?

Over the years, cases of fraud have been discovered where donors have been lying about their characteristics. The question raised by such cases is what the responsibility of the gamete bank is for the non-medical information provided by the donor. The problem is that extended donor profiles contain a large amount of information about different aspects of the donor's life and that not all this information can be verified or is worth verifying. Two cases are scrutinized in more detail: education and criminal record. The proposed solution is to split the donor information into a verified and a non-verified part with the non-verified part falling under the responsibility of the donor. The question of what information should be included in the verified part of the donor profile is still open.

Age-based restrictions on reproductive care: discerning the arbitrary from the necessary.

Policies that determine whether someone is allowed access to reproductive healthcare or not vary widely among countries, especially in their age requirements. This raises the suspicion of arbitrariness, especially because often no underlying justification is provided. In this article, we pose the question-under which circumstances is it morally acceptable to use age for policy and legislation in the first place? We start from the notion that everyone has a conditional positive right to fertility treatment. Subsequently, we set off to formulate a framework that helps to determine who should be excluded from treatment nonetheless. The framework's three core elements are: choosing and ethically justifying exclusion criteria (target), determining the actual limit between in- and exclusion (cut-off), and selecting variables that help to predict the exclusion criteria via correlation (as they are not directly measurable) (proxy). This framework allows us to show that referring to age in policy and legislation is only ethically justifiable if there is a sufficiently strong correlation with a non-directly measurable exclusion criterion. Moreover, since age is only one of many predicting variables, it should therefore not be ascribed any special status. Finally, our framework may be used as an argumentative scheme to critically assess the ethical legitimacy of policies that regulate access to (fertility) treatments in general.

An invisible caregiver for visibly older parents: Experiences of (young) adults shared as comments to newspaper articles on advanced age parenthood.

At the centre of the debate on advanced age parenthood are concerns for the offspring's well-being. In the few empirical studies available, researchers found that children born to older parents show similar or better cognitive, behavioural and psychosocial outcomes compared to children born to younger parents. Most of these studies examining the children's perspective are quantitative. This study qualitatively examined the experiences presented by (young) adults who identified as born to older parents offered in response to a selection of newspaper articles on the topic. Performing inductive thematic analysis, we found that positive experiences were often presented as a way to contradict prejudices about advanced age parenthood. Other comments described the visual representation of the older parents' age as an attribute that created difference and, in some cases, social distance from peers and the outside world in general. Central to the negative experiences was a contrast between the visibility of being a child of older parents and the invisibility of caring for them. Moreover, in a majority of the latter comments, the commenters' caregiving experiences combined with the social network's notable lack of understanding and support regarding the caregiving responsibilities were described as adversely affecting their lives. These findings provide more insight into the experiences of (young) adults born to advanced age parents and their potential needs.

"It was not an accident": Women's experiences of renewing motherhood at 40.

In recent decades, there has been an increase in motherhood at an advanced age that has raised several medical and social concerns. We conducted a qualitative interview study, guided by Interpretative Phenomenological Analysis, to focus on the motivations and experiences of Belgian women who 'renewed' their motherhood later in life, meaning they had one or several children and then (at least 10 years later) had another child at the age of 40 or older. We focused on ten women's experiences of motherhood later in life, as well as on the way they managed social norms and expectations regarding family building and the appropriate life course. We identified two main themes. The first theme describes the participants' encounters with social norms that challenged their decision to reproduce and parent later in life, and how they managed and anticipated criticism, surprise, disbelief and incomprehension about their renewed motherhood in various ways. The second theme shows how these women talked about taking responsibility as a (renewed) mother of advanced age. For them, responsible motherhood involved making thoughtful reproductive choices, attending to the range of needs of their children, and making extra efforts to safeguard the social and emotional wellbeing of their youngest children, thereby seeking to reduce potential harm resulting from these reproductive choices. This study provides insight into these women's self-conception and their interactions with prejudiced social views of motherhood and family building.

Why we need stem-cell derived gametes.

In-vitro gametogenesis (IVG) is almost exclusively discussed as a potential solution for people who have no (functional) gametes. However, IVG could also be seen as an alternative to standard IVF. Instead of submitting women to ovarian stimulation and invasive oocyte retrieval, the creation of oocytes from stem cells should be the first treatment option (assuming it to be reasonably safe and effective). The primary reason for the application of this method would not be for these women to become genetic parents but to alleviate the physical and psychological burden of standard IVF treatment on them.

Lowering the age limit of access to the identity of the gamete donor by donor offspring: the argument against.

Countries that abolished donor anonymity have imposed age limits for access to certain types of information by donor offspring. In the UK and the Netherlands, a debate has started on whether these age limits should be lowered or abolished all together. This article presents some arguments against lowering the age limits as a general rule for all donor children. The focus is on whether one should give a child the right to obtain the identity of the donor at an earlier age than is presently stipulated. The first argument is that there is no evidence that a change in age will increase the total well-being of the donor offspring as a group. The second argument stresses that the rights language used for the donor-conceived child isolates the child from his or her family and this is unlikely to be in the best interest of the child. Finally, lowering the age limit reintroduces the genetic father in the family and expresses the bionormative ideology that contradicts gamete donation as a practice.

When elective egg freezers become egg donors: practical and ethical issues.

Many people hope that the unused and unwanted eggs frozen by women for self-use could be applied to reduce the shortage of donor eggs. However, several practical (additional screening and counselling) and ethical (informed consent and reimbursement) issues may dampen this hope. This paper also considers the question of whether elective egg freezers who want to donate their eggs should be reimbursed for the costs they have met for the IVF cycle and storage. It is argued that a partial reimbursement for the collection (hormonal stimulation and retrieval) is morally acceptable because it is limited to proven expenses (and does not violate the altruism rule) and because the recipients should contribute to the costs of a scheme from which they are benefiting. The storage fee should be paid by the egg freezer herself and no reward for effort, time and inconvenience should be given. This compromise benefits both donors and recipients.

Experiences and attitudes of Danish men who were sperm donors more than 10 years ago; a qualitative interview study.

BACKGROUND: More knowledge about the long-term impact of sperm donation is essential as the donor's attitude towards donation may change over time. Personal and social developments may prompt a rethinking of previous actions and decisions, or even regret. Thus, the aim of this study was to explore the experiences and attitudes of men who were sperm donors more than 10 years ago. METHODS: From May to September 2021, semi-structured, qualitative interviews were conducted with 23 former donors (> 10 years since last donation) from Cryos International sperm bank. Two participants were non-anonymous donors and 21 were anonymous. The interviews were conducted by phone or via video (mean 24 minutes). All interviews were recorded, transcribed verbatim and rendered anonymous. Data were analyzed using thematic analysis. RESULTS: The analysis showed that most men had been donors for monetary and altruistic purposes, and now considered sperm donation as a closed chapter that was 'unproblematic and in the past'. Most men valued anonymity and emphasized the non-relatedness between donor and donor conceived offspring. Knowledge about recipients and donor offspring was seen as 'damaging' as it could create unwanted feelings of relatedness and responsibility towards them. All men acknowledged donor conceived persons' potential interests in knowing about their genetic heritage in order to understand appearance and personal traits, but also emphasized the donors' rights to anonymity. Potential breach of anonymity was generally considered 'highly problematic' as it was expected to disturb their families and force a relationship on them. CONCLUSION: This study reports on former donors who might not have volunteered for research due to lack of interest or protection of privacy. The majority of men valued anonymity and clearly demarcated a line between sperm donation and fatherhood, which was enforced by not knowing about the donor offspring or recipients.

An analysis of the outcome of 11 712 men applying to be sperm donors in Denmark and the USA.

STUDY QUESTION: Is the outcome of donor recruitment influenced by the country in which recruitment took place or the initial identity (ID)-release choice of applicants? SUMMARY ANSWER: More applicants are accepted as donors in Denmark than in the USA and those who choose ID release are more frequently accepted than those who do not. WHAT IS KNOWN ALREADY: The successful recruitment of sperm donors is essential to provide a range of medically assisted reproduction (MAR) procedures, which rely upon donor sperm. However, while much has been written about the medical screening and assessment of sperm donors from a safety perspective, relatively little has been written about the process of recruiting donors and how it works in practice. There are differences in demographic characteristics between donors who choose to allow their identity to be released to their donor offspring (ID release) compared to those who do not (non-ID release). These characteristics may also influence the likelihood of them being recruited. STUDY DESIGN, SIZE, DURATION: A total of 11 712 men applied to be sperm donors at a sperm bank in Denmark and the USA during 2018 and 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: Anonymized records of all donor applicants were examined to assess the number passing through (or lost) at each stage of the recruitment process. Statistical analysis was carried out to examine differences between location (Denmark or USA) and/or donor type (ID release versus non-ID release). MAIN RESULTS AND THE ROLE OF CHANCE: Few applicants (3.79%) were accepted as donors and had samples frozen and released for use; this was higher in Denmark (6.53%) than in the USA (1.03%) (χ2 = 243.2; 1 degree of freedom (df); z = 15.60; P < 0.0001) and was higher in donors who opted at the outset to be ID release (4.70%) compared to those who did not (3.15%) (χ2 = 18.51; 1 df; z = 4.303; P < 0.0001). Most candidate donors were lost during recruitment because they: withdrew, failed to respond, did not attend an appointment, or did not return a questionnaire (54.91%); reported a disqualifying health issue or failed a screening test (17.41%); did not meet the eligibility criteria at the outset (11.71%); or did not have >5 × 106 motile sperm/ml in their post-thaw samples (11.20%). At each stage, there were statistically significant differences between countries and the donor's initial ID choice. During recruitment, some donors decided to change ID type. There were no country differences in the frequency in which this occurred (χ2 = 0.2852; 1 df; z = 0.5340; P = 0.5933), but it was more common for donors to change from non-ID release to ID release (27.19%) than the other way around (11.45%) (χ2 = 17.75; 1 df; z = 4.213; P < 0.0001), although movements in both directions did occur in both countries. LIMITATIONS, REASONS FOR CAUTION: No information was available about the demographic characteristics of the applicants, which may also have influenced their chances of being accepted as a donor (e.g. ethnicity and age). Donor recruitment procedures may differ in other locations according to local laws or guidelines. WIDER IMPLICATIONS OF THE FINDINGS: A better understanding of when and why candidate donors are lost in the recruitment process may help develop leaner and more efficient pathways for interested donors and sperm banks. This could ultimately increase the number of donors recruited (through enhanced information, support, and reassurance during the recruitment process) or it may reduce the financial cost to the recipients of donor sperm, thus making it more affordable to those who are ineligible for state-funded treatment. STUDY FUNDING/COMPETING INTEREST(S): The study received no funding from external sources. All authors are Cryos employees or members of the Cryos External Scientific Advisory Committee. TRIAL REGISTRATION NUMBER: N/A.

Deconstructing age(s): an analysis of the different conceptions of age as a legal criterion for access to assisted reproductive technologies.

Whether there should be restrictions for access to Assisted Reproductive Technologies (ART) is a matter of continuous medical, societal, and ethico-legal debate. One of the most controversial topics in this context is the use of parental age as a criterion to limit access to ART. Views are divided on whether there should be an upper age limit for one or both parents and on where such limits should be. Although this debate is centered around the issue of 'age' and although age-related limits are present in many legislations, the intrinsic ambiguity of the term `age' is largely overlooked. In this article, we build on gerontological, medical, and sociological literature on the concepts of 'age' and 'aging' to distinguish three conceptions of age that are relevant for ART regulation: the chronological, the biological, and the social-cultural one. Beyond mapping out these conceptions of age, we describe how they relate to ART and reproduction, and illustrate the advantages and disadvantages of relying on each of them as a basis for limiting ART access. Finally, we propose a template for defining legal age limits for ART access in the law, based on the refined understanding of the different conceptions of age that we outline and we discuss two potential objections to our proposal.

The forgotten group of donor-conceived persons.

A forgotten group of donor-conceived persons is those who believe that gamete donation is morally wrong and should be prohibited. Although they share the two main arguments with the anti-anonymity group, i.e. the psychological harm as a consequence of lacking the necessary information for identity construction, and the violation of a fundamental human right, namely the right to be cared for by one's genetic parents, their voices are largely ignored in the debate. The anti-donation group also has a large part of the ideology of the family in common with the anti-anonymity group. The paper concludes that the anti-donation position should be accepted as an equivalent position. Moreover, given the similarities between the two positions, people who accept the claims of the anti-anonymity donor-conceived persons should explain why the claims of the anti-donation group should not be honoured.

Sperm sharing: as problematic as oocyte sharing?

Sperm sharing has recently been introduced in a number of clinics in the UK. In all gamete sharing schemes, two goals can be distinguished: increasing the donor pool and enabling less affluent patients to access IVF treatment. This article compares sperm sharing with oocyte sharing in order to determine whether the differences and similarities affect the moral acceptability of the practice. It then compares sperm sharers with regular sperm donors and notices that sperm sharers seem to have fewer rights than regular sperm donors. The next step is to look at the alternatives to reach the two goals of sharing schemes. Regarding the first goal of increasing the donor pool, there are alternative procedures that are minimally coercive and where less affluent people are not targeted. Regarding the goal of increasing access to IVF treatment, clinics could propose cheaper IVF protocols to less affluent people or offer the IVF cycle at reduced prices. I conclude that the ethical problems caused by sharing schemes that offer financial benefits in return for oocytes or sperm can be avoided by using alternatives.

Oocyte vitrification for elective fertility preservation: a SWOT analysis.

Oocyte vitrification, also known as egg freezing, is increasingly being used by women as a precautionary measure against the anticipated decline in fertility. In countries where this procedure is allowed, elective oocyte vitrification has become an integral part of the treatment portfolio of fertility clinics. The widespread tendency towards the postponement of motherhood and the advances in laboratory technologies are encouraging women to consider oocyte vitrification and, by doing so, increase their reproductive autonomy. However, elective oocyte vitrification, or elective egg freezing (EEF), still elicits controversy, not only when EEF is appraised from a cost-efficiency point of view, but also in terms of medical and ethical concerns. In general, although the laboratory tool of vitrification has revolutionized the treatment of infertility, the pros and cons need to be clarified when considering EEF.
