Abstract
Embryo donation (ED) involves the donation of surplus embryos post family formation to others in need. Commensurate with Australian and New Zealand legislation and policy, ED is practiced as an identity-release programme shaped by four paramount principles. These include: the need to consider the longitudinal health and well-being of donor-conceived children born from assisted reproductive technologies (ART); recognition that offspring should be made aware of and be able to access information about their genetic origins; awareness that the short and long-term health and psychological welfare of other stakeholders (i.e., recipients and donors) should be ensured; and finally, that all donations are altruistic. Whilst embedded in ART legislation or professional guidelines, how these principles are operationalized through counselling in both countries remains variable. In this paper, we draw upon Australian and New Zealand research, legislation and policy shaping the counselling milieu. We highlight some of the key clinical issues that counsellors need to explore with participants of an ED arrangement and the implications of these as they apply to dilemmas within counselling practice such as counsellor roles and responsibilities.

Abstract
PURPOSE To explore perceptions towards embryo disposition among patients donating excess embryos to a research biobank. METHODS Cross-sectional study of survey responses collected as part of enrollment in a research biobank. Patients are asked questions regarding the difficulty of their disposition decision, their alternative disposition choice if donation to research was not available, quality of the counseling they received, and if additional counseling throughout their treatment would have been beneficial. Survey responses use 5-point Likert scales, with "1" being lowest/least and "5" being highest/most. RESULTS A total of 157 men and 163 women enrolled in the biobank. Median scores for difficulty of disposition decision were 3 for females and 2 for males, and for quality of counseling, the median scores were 4 for females and 3 for males. Seventy percent of patients would have chosen to discard their excess embryos had donation to research not been an option. Statistical analyses showed no significant difference in responses based on variations in race, religion, sexual orientation, and infertility diagnoses. Concordance of responses within heterosexual couples was tested and found to be poor to moderate. CONCLUSIONS Assessing patients' perceptions towards embryo disposition after donation of their excess embryos to a research biobank affords a unique perspective. The difficulty of the disposition decision, the tendency to discard embryos in the absence of a means for donation to research, and the poor agreement between heterosexual partners highlight the importance of donation to research as an accessible disposition option and the need for a personalized approach to counseling and consenting for embryo disposition.

Caughey LE, Lensen S, White KM, Peate M. Disposition intentions of elective egg freezers toward their surplus frozen oocytes: a systematic review and meta-analysis. Fertil Steril 2021; 116:1601-1619. [PMID: 34452749 DOI: 10.1016/j.fertnstert.2021.07.1195] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 07/11/2021] [Accepted: 07/12/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To examine the disposition outcomes and disposition intentions of elective egg freezers (EEFs) toward their surplus frozen oocytes and the psychosocial determinants underlying these. DESIGN A systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Actual EEFs (women with oocytes in storage), potential EEFs (women investigating elective oocyte cryopreservation or about to freeze their oocytes), and women of reproductive age (women in the community aged ≥18 years). INTERVENTION(S) A systematic review was undertaken and electronically searched MEDLINE, Embase, and PsycINFO on the Ovid platform for conference abstracts and peer-reviewed articles, published in English after January 1, 2010. A search strategy combined synonyms for oocyte, cryopreservation, donation, disposition, elective, and attitude. Eligible studies assessed disposition outcomes (how an oocyte was disposed of) and disposition intentions (how women intend to dispose of an oocyte) and/or the psychosocial determinants underlying disposition outcomes and intentions. The Joanna Briggs Institute Prevalence Tool was used to assess the risk of bias. A meta-analysis using random effects was applied to pool proportions of women with similar disposition intentions toward their oocytes. MAIN OUTCOME MEASURE(S) Disposition outcomes and intentions toward surplus frozen oocytes: donate to research; donate to others; discard; unsure. Psychosocial determinants (beliefs, attitudes, barriers, and facilitators) of disposition outcomes and intentions. RESULT(S) A total of 3,560 records were identified, of which 22 (17 studies) met the inclusion criteria (8 studies from Europe, 7 from North America, and 2 from Asia). No studies reported on past oocyte disposition outcomes. Seventeen studies reported on the future disposition intentions of 5,446 women. Only 2 of the 17 studies reported on the psychosocial determinants of oocyte disposition intentions. There was substantial heterogeneity in the pooled results, which was likely a result of the significant variation in methodology. Actual EEFs were included in eight studies (n = 873), of whom 53% (95% confidence interval [CI], 44-63; I2, 87%) would donate surplus oocytes to research, 31% (95% CI, 23-40; I2, 72%) were unsure, 26% (95% CI, 17-38; I2, 92%) would donate to others, and 12% (95% CI, 6-21; I2, 88%) would discard their eggs. Psychosocial determinants: One study reported that 50% of these women were aware of friends and/or family having difficulty conceiving, which may have contributed to their willingness to donate to others. Potential EEFs were included in 4 studies (n = 645), of whom 38% (95% CI, 28-50; I2, 84%) would donate to research, 32% (95% CI, 17-51; I2, 91%) would donate to others, 29% (95% CI, 17-44; I2, 89%) would discard, and 7% (95% CI, 1-27; I2, 77%) were unsure. Psychosocial determinants: No studies. Women of reproductive age were included in 5 studies (n = 3,933), of whom 59% (95% CI, 48-70; I2, 97%) would donate to research and 46% (95% CI, 35-57; I2, 98%) would donate to others. "Unsure" and "discard" were not provided as response options. Psychosocial determinants: One study reported that the facilitators for donation to others included a family member or friend in need, to help others create a family, financial gain, to further science, and control or input over the selection of recipients. Barriers for donation included fear of having a biological child they do not know or who is raised by someone they know. CONCLUSION(S) No studies reported on the disposition outcomes of past EEFs. Disposition intentions varied across the three groups; however, "donating to research" was the most common disposition preference. Notably, the second disposition preference for one-third of actual EEFs was "unsure" and for one-third of potential EEFs was "donate to others." There were limited studies for actual and potential EEFs, and only two studies that explored the psychosocial determinants of oocyte disposition intentions. Additionally, these data suggest that disposition decisions change as women progress on their egg freezing journey, highlighting the importance of ongoing contact with the fertility team as intentions may change over time. More research is needed to understand the psychosocial determinants of oocyte disposition decisions so fertility clinics can provide EEFs with the support and information they need to make informed decisions about their stored eggs and reduce the level of uncertainty reported among EEFs and the potential risk of psychological distress and regret. CLINICAL TRIAL REGISTRATION NUMBER PROSPERO 2020: CRD42020202733.

Analysis of clinical factors and reasons that influence the disposition of cryopreserved embryos in Japanese patients with infertility treated in our clinic. J Obstet Gynaecol Res 2021; 47:1425-1432.

Abstract
AIM To investigate the clinical factors and factors that affect the decisions regarding storage of cryopreserved embryos obtained using assisted reproductive technology. METHODS Clinical characteristics affecting the decisions regarding cryopreserved embryos were analyzed in 5724 Japanese couples who underwent in vitro fertilization (IVF) or intra-cytoplasmic sperm insemination (ICSI) and embryo transfer over 4 years since April 2015 at our clinic. Statistical analysis was carried out using JMP software. RESULTS The number of oocytes retrievals and embryos stored, outcomes and number of children, and age of the female patients and male partners were related to the decision-making regarding cryopreserved embryos. Childbearing and no wish for another child were the major reasons for discontinuing embryo storage. The number of oocytes retrievals and embryos in storage, age of the female patients, and sex of the child were independently associated with this decision-making in 2682 patients with a single child. Women with male children were more likely to choose discontinuation of embryo storage than those with female children. CONCLUSION Already having a child and not wishing for further treatment due to age along with the presence of a male child affect the decision to continue or discontinue embryo storage in Japanese patients with infertility.

Abstract
Background The aim of this study was to investigate attitudes towards embryo donation and embryo donation families among professionals working in primary child healthcare, and their experiences of these families. Methods A cross-sectional online survey was conducted in Sweden between April and November 2016. A total of 712 primary healthcare physicians, registered nurses and psychologists were approached to participate in this study. The study-specific questionnaire measured attitudes and experiences in the following four domains: legalisation and financing, the family and the child’s health, clinical experience of meeting families following embryo donation, and knowledge of embryo donation. Results Of the 189 women and 18 men who completed the questionnaire (response rate 29%), relatively few (13%) had clinical experience of caring for families following embryo donation. Overall, 69% supported legalisation of embryo donation for infertile couples, and 54% agreed it should be publicly funded. The majority (88%) agreed the child should have the right to know the donors’ identity. Respondents did not believe that children conceived through embryo donation are as healthy as other children (50%), citing the risks of poor mental health (17%) and social stigmatization (18%). Approximately half reported low confidence in their own knowledge of embryo donation (47%) and wanted to know more (58%). Conclusions These results indicate relatively large support among healthcare professionals in Sweden for the legalisation of embryo donation. In order to provide adequate healthcare to families following embryo donation, there is a need to develop educational resources to increase knowledge about the medical and psychosocial consequences of embryo donation among healthcare professionals working in primary healthcare.

Abstract
OBJECTIVE To investigate infertility patients' attitudes towards frozen embryos and the factors that influence patients' decisions. STUDY DESIGN This is a cross-sectional quantitative observational study conducted between 1 April 2010 and 1 April 2015. Patients underwent IVF with embryo cryopreservation and successfully delivered at least one baby were called to complete a questionnaire regarding decisions about embryo disposition and reasons for their preferred option. The chi-square test was used to compare the attitudes about embryo disposition between subgroups. A multinomial logistic regression was performed to examine the effects of various individual characteristics on the decision. The effects were presented by adjusted odds ratios (OR) and their 95% confidence interval (95% CI). SETTING Guangzhou Women and Children's Hospital. RESULTS Among 769 interviewed couples, 718 couples (93.4%) completed the questionnaire. A total of 462 couples (64.3%) continued to store embryos. Among the participants who discontinued storage, 214 couples (83.6%) chose to discard embryos, and 42 couples (16.4%) agreed to donate embryos for research. Having no college education and longer storage duration were associated with an increase in the likelihood of discontinuing storage. The couples having twins from IVF were more likely to discontinue storage (OR=6.33, 95%CI: 4.37-9.39) compared to those having only one child. Regarding the choice of discarding or donation for research among those who decided to discontinue frozen embryos, females aged 30 or above were more willing to donate their embryos for research (OR=2.85, 95%CI:1.12-7.23). CONCLUSION The preference for embryo disposition was associated with the number of children, storage duration, and the couple's education. Chinese patients generally chose to store cryopreserved embryos and were less receptive to the concept of embryo research compared with patients in other developed countries.

Abstract
Although in vitro fertilization (IVF) has offered hope to those struggling with infertility, it has also had some unintended consequences, including the fate of embryos that may be "surplus" to requirement following IVF treatment. The number of embryos in storage across the world is high, creating a dilemma for patients who need to make disposal decisions, as well as presenting an administrative and practical dilemma for clinics. Research has suggested that patients' views of the status of their embryo/s may affect their disposal decisions, and yet the nature of the links between views of the embryo and decisions to either donate or discard remain unclear. In this article, we engage in a discursive analysis of literature on disposal decisions. We discuss the range of ways in which embryos may be constructed, and demonstrate how these discourses make available or constrain particular action possibilities, and offer particular subject positions for patients. The analysis highlights the complexity of the relationship between embryo status and decision making, and may assist clinicians in supporting and guiding patients' decisions.

Abstract
Genetic relatedness poses significant challenges to traditional practices of medical ethics as concerns the biobanking of human biological samples. In this paper, we first outline the ethical challenges to informed consent and confidentiality as these apply to human biobanks, irrespective of the type of tissue being stored. We argue that the shared nature of genetic information has clear implications for informed consent, and the identifying nature of biological samples and information has clear implications for promises of confidentiality. Next, with regard to the special case of biobanking human embryos and eggs, we consider issues arising from: first, the type of tissues being stored; second, the use to which these tissues are put; and third, how this plays out given the shared and identifying nature of these tissues. Specifically, we examine the differences between human bodily tissues and human reproductive tissues focusing on the assumed potential of the reproductive tissues and on the possible greater emotional attachment to these tissues because of their real and imagined kinship. For some donors there may be a sense of family connection with embryos and eggs they once thought of as 'children-in-waiting'. Finally, we conclude by considering the implications for ethical practice.

Abstract
OBJECTIVE The objective of this study was to identify factors that contribute to patient decision-making for disposition of surplus cryopreserved embryos in Canada. METHODS In 2013, interviews were conducted with 45 IVF patients from three clinic sites, representing a total of 33 households. Patients interviewed all had unused cryopreserved embryos in storage in 2010. Initial demographic data collection was followed by one in-depth semi-structured interview conducted in 2013. Data were managed and coded thematically. RESULTS Most patients (21 patients, representing 16 households) renewed storage agreements to keep embryos in storage at the time of the interview. Among patients who did not renew their storage agreements at some point between 2010 and 2013, six patients (representing 5 households) had since used all their embryos, two patients (representing one household) had decided to keep their embryos in storage in perpetuity, three patients (representing 3 households) discarded their embryos outright, and 13 patients (representing 9 households) donated their embryos to research or clinical training. Among patients who donated to research or clinical training, three key themes emerged: a desire to "give back," to contribute to scientific progress, and to avoid "wasting" embryos. These patients were not always certain about whether they had chosen research or clinical training. CONCLUSION This study demonstrates the applicability of international findings about embryo disposition decision-making to the Canadian setting. Moreover, it identifies that while patients making disposition decisions often choose to donate embryos to research and/or clinical training, they are not always certain about what these options entail. Clinicians, counsellors, and others must ensure that patients are not only aware of their embryo disposition options, but that they understand the nature of these options as well.
