Gamete donors' and recipients' evaluation of donor counselling: a prospective longitudinal cohort study

Comparing the psychological outcomes of donor and non-donor conceived people: A systematic review

BACKGROUND

Over 70 000 donor-conceived (DC) people have been born in the UK since 1991. Little is known about their long-term psychological outcomes and no systematic review has assessed these.

OBJECTIVES

To conduct a systematic review of the psychological experiences of DC people through childhood and adulthood (Prospero: CRD42021257863).

SEARCH STRATEGY

Searches of Cumulative Index to Nursing and Allied Health Literature (CINHAL), the Excerpta Medica database (Embase), MEDLINE® and PsycINFO, conducted on 4 January 2024.

SELECTION CRITERIA

Quantitative and qualitative studies were included if: there were five or more participants; they were peer reviewed; and any DC psychological outcomes were assessed. No limits on date, language or country were applied.

DATA COLLECTION AND ANALYSIS

Double screening, selection, data extraction and quality assessment were performed, using Joanna Briggs Institute (JBI) scoring.

MAIN RESULTS

Fifty studies (with 4666 DC participants), mostly from high-income anglophone countries, with heterogeneity of design, populations and outcome measures, were included. Of 19 comparative studies, 14 found no difference in outcomes between DC and non-DC people, ten found better outcomes (in health, well-being, self-esteem and emotional warmth) and six found worse outcomes (increased autism spectrum disorder and attention deficit hyperactivity disorder, addiction issues, mental illness, disruptive behaviour and identity problems). Qualitative data revealed common themes relating to identity formation, mistrust and concerns regarding genetic heritage. The evidence regarding adulthood outcomes was very limited.

CONCLUSIONS

The research on DC individuals presents a nuanced picture, with most studies suggesting comparable or improved outcomes in terms of well-being and relationships, but with a notable minority indicating higher rates of mental health and identity struggles. Qualitative findings underscore common negative experiences, whereas the early disclosure of DC status appears beneficial for psychological well-being.

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.

Shifting to a model of donor conception that entails a communication agreement among the parents, donor, and offspring

Background

Some persons conceived with donor gametes react negatively when they found their birth via donor conception. They request access to information about and seek to communicate with the donor. However, some countries mandate donor anonymity. Other countries allow donor-conceived persons to access donor information, but they can only use this access if their parents have disclosed donor conception to them. We investigated a thorny issue of donor conception: whether donor conception should be shifted from an anonymous basis to a non-anonymous basis.

Methods

We review the issues and concerns regarding donor conception. We then consider the impact of direct-to-consumer genetic testing on donor conception, as well as the influence of donor conception on offspring’s identity and the potential of different types of donors. To discuss the future policy of donor conception, the policies on the anonymity of gamete donors were investigated using publicly-available documents in 15 countries.

Results

The aim of mandating donor anonymity is to protect the privacy of the donor and intended parents. However, the diffusion of direct-to-consumer genetic testing may make it impossible to maintain anonymity. Birth via donor conception shapes the offspring’s identity, and the donor may further influence the development of offspring’s identity through communications. It remains important to disclose donor conception to donor-conceived offspring and to provide them with donor information. However, that information might be insufficient for some donor-conceived persons. Here are benefits to having open-identity donors and known donors. Such donors can make an agreement with the parents regarding future communication with the offspring, although both sides should respect privacy. Subsequent counseling for all parties involved can result in better tripartite communication agreements.

Conclusions

In sum, ethical and practical issues that complicate donor anonymity are driving a shift to non-anonymous donor conception, in which all parties come to a communication agreement. To pave the way for such a donor conception system, transitional measures can be put into place. For countries that already adopted non-anonymous donor conception, ensuring the communication agreements is important to protect the rights of parents, donor, and offspring.

Cross-Border Reproductive Care: Psychological Distress in A Sample of Women Undergoing In Vitro Fertilization Treatment with and without Oocyte Donation

Background

Cross-border reproductive care (CBRC) refers to the movement of patients to foreign countries for fertility treatment. Limited evidence indicates that this phenomenon is associated with a risk of psychologi- cal distress, but few studies on the psychological impact of CBRC are currently available. The aim of this study was to compare the anxiety and depression levels of a group of cross-border patients with a local Spanish patient group, both of which underwent in vitro fertilization (IVF) treatment. We also sought to explore the clinical, sociodemographic and personality profiles of the CBRC group and local women.

Materials and Methods

This present cross-sectional study was conducted on 161 infertile females (71 CBRC patients and 90 local women) who were undergoing IVF treatment. The following questionnaires were used to collect data: Spielberger State Anxiety Inventory (STAI-S), the Beck Depression Inventory-II (BDI-II) and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). Sociodemographic, clinical, reproductive and CBRC variables were also recorded.

Results

CBRC patients, specifically CBRC oocyte recipients, showed higher levels of anxiety compared to lo- cal women. However, no significant differences in depression scores were found between both groups. Finally, when analysing personality, the Activity scale scores of the ZKPQ were found to be higher in CBRC oocyte recipients, which indicated a greater tendency for general activity and higher energy levels.

Conclusion

CBRC oocyte recipient women may have greater vulnerability to anxiety than local women prior to infertility treatment. Screening and psychological support protocols for anxiety in this population should be considered.

A mental health program for infertile couples undergoing oocyte donation: protocol for a mixed methods study

Background

The psychological consequences of infertility in couples undergoing oocyte donation differ culturally, racially, religiously, and legally from other infertile couples undergoing assisted reproductive treatments. Therefore, the inclusion of a mental health program in assisted reproductive services is essential for these couples. As such, the aim of this study is to develop a program for improving the mental health of these couples.

Methods

This study is designed using an exploratory mixed method and the program based on Talbot and Verrinder model. Different steps of this research include determination of a specific topic for planning (needs assessment), initial design of the program, finalization of the program (using the views of experts in this area), implementation of the program, monitoring of the implementation of the program and evaluation of the program. To perform the first step of Talbot’s program, the first phase of the study will be conducted. At first, through a qualitative study, the items of the questionnaire are designed and then its psychometric steps will be performed by a cross-sectional study. In the second and third steps, the classic Delphi technique will be used in four-round for initiation and finalization of the program, and the second phase will be completed. The fourth, fifth and sixth steps of the program including implementation, monitoring of the implementation and evaluation of the program in the future will be performed.

Discussion

Designing an appropriate program based on the documentations of the qualitative study and evidence can improve the mental health and quality of life of the couples undergoing oocyte donation. The program, based on the measurement of needs, will be implemented using a tool designed specifically for the target population and can be useful in the processes of treatment, education, policymaking and legislation as well as research.

New realities for the practice of egg donation: a family-building perspective

The practice of egg donation in the United States has been based on assumptions about secrecy, anonymity, and contact among the parties that require reexamination. This article argues for the need to acknowledge that secrecy and anonymity are no longer viable assumptions and that all parties may have a strong interest in contact and connection. A shift in the narrative for the practice of egg donation from a purely medical perspective to a broader family-building perspective is described. Significant practice changes to accommodate the new realities, rooted in a family-building perspective, are outlined in the arenas of medical record retention, informed consent, recipient and donor preparation and counseling, facilitation of contact among the parties, and outreach to other medical professionals, with the goal of promoting not only healthy pregnancy, but also long-term positive family functioning.

Counsellors' practices in donor sperm treatment

When intended parents choose to have donor sperm treatment (DST), this may entail wide-ranging and long-lasting psychosocial implications related to the social parent not having a genetic tie with the child, how to disclose donor-conception and future donor contact. Counselling by qualified professionals is recommended to help intended parents cope with these implications. The objective of this study is to present findings and insights about how counsellors execute their counselling practices. We performed a qualitative study that included 13 counsellors working in the 11 clinics offering DST in the Netherlands. We held a focus group discussion and individual face-to-face semi-structured interviews, which were fully transcribed and analysed using thematic analysis. The counsellors combined screening for eligibility and guidance within one session. They acted according to their individual knowledge and clinical experience and had different opinions on the issues they discussed with intended parents, which resulted in large practice variations. The counsellors were dependent on the admission policies of the clinics, which were mainly limited to regulating access to psychosocial counselling, which also lead to a variety of counselling practices. This means that evidence-based guidelines on counselling in DST need to be developed to provide consistent counselling with less practice variation.

Exploring parents' feelings about counseling in donor sperm treatment

INTRODUCTION

How do parents feel about psychosocial counseling during donor sperm treatment?

METHODS

We performed a qualitative study based on semi-structured in-depth interviews, conducted from July 2012 until August 2013, with 24 Dutch parents who had had children through donor sperm treatment between 2000 and 2012.

RESULTS

During counseling, parents sometimes felt screened for their eligibility for parenthood rather than guided, and therefore felt discouraged about bringing up topics that were important for them. Parents of all family types would value extended psychological counseling before and after successful donor sperm treatment, that is in several stages of parenthood. Only after childbirth topics such as disclosure, fear of rejection of the social parent and future contact of the child with the sperm donor became more pertinent.

CONCLUSIONS

Both before and after childbirth, parents of all family types would value expert advice on when and how to disclose. Psychosocial guidance should be offered separately from psychosocial screening for treatment eligibility and should be offered in several stages of parenthood.

Donor Conception Disclosure: Directive or Non-Directive Counselling?

It is widely agreed among health professionals that couples using donor insemination should be offered counselling on the topic of donor conception disclosure. However, it is clear from the literature that there has long been a lack of agreement about which counselling approach should be used in this case: a directive or a non-directive approach. In this paper we investigate which approach is ethically justifiable by balancing the two underlying principles of autonomy (non-directive approach) and beneficence (directive approach). To overrule one principle in favour of another, six conditions should be fulfilled. We analyse the arguments in favour of the beneficence principle, and consequently, a directive approach. This analysis shows that two conditions are not met; the principle of autonomy should not be overridden. Therefore, at this moment, a directive counselling approach on donor conception disclosure cannot be ethically justified.

Embryo donation and counselling for the welfare of donors, recipients, their families and children

STUDY QUESTION

How do counsellors facilitating known 'open' embryo donation (ED) experience their roles and responsibilities?

SUMMARY ANSWER

Counsellors regard counselling for ED as entailing significant responsibility to ensure that the longer-term implications of the practice are understood and that positive relationships are established that will promote the well-being of donors, recipients, their families and the children involved.

WHAT IS KNOWN ALREADY

While counselling is frequently recommended in third-party assisted reproduction, there has been little research into the experiences of counsellors and their perceptions of their roles and responsibilities.

STUDY DESIGN, SIZE, DURATION

Fertility counsellors were interviewed between March and October 2012 as to their experiences and perceptions of their roles and responsibilities.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Fertility counsellors were recruited from across New Zealand and interviews were conducted with all nine counsellors involved in ED counselling. Interview data were analysed thematically to identify main themes.

MAIN RESULTS AND THE ROLE OF CHANCE

Counsellors regard ED as a complex practice with enduring implications arising from the genetic link between donors and offspring, which is seen to bestow immutable social ties. They see their role as the provision of implications counselling and the facilitation of ongoing positive relationships between donors and recipients in an 'open' context. Counsellors express concern about their responsibility for promoting the welfare of all parties--including that of the child--the limitations of counselling, and the conflation of assessment and counselling roles.

LIMITATIONS, REASONS FOR CAUTION

Experiences of counselling for ED may change over time as longer-term outcomes become more apparent.

WIDER IMPLICATIONS OF THE FINDINGS

Further consideration needs to be given as to how the welfare principle may best be operationalised in counselling practice, particularly in contexts of 'open' donation.

Outcomes of surrogacy undertaken by Australians overseas

OBJECTIVES

To describe the outcomes of surrogacy among Australian intended parents who engage in compensated surrogacy overseas.

DESIGN, SETTING AND PARTICIPANTS

Members of two Australian parenting support forums who were considering surrogacy or were currently or previously in a surrogacy arrangement were invited to complete an anonymous online survey during July 2013.

MAIN OUTCOME MEASURES

Destination countries; source of eggs; number of surrogates and embryo transfers; proportions who experienced pregnancy loss after 12 weeks' gestation, multiple pregnancy, prematurity, and live birth by destination country; and intentions regarding disclosure to children about the way they were conceived.

RESULTS

Of 1135 potential participants 259 (23%) completed the survey. Of these, 112 (43%) had undertaken at least one surrogacy attempt overseas. India and the United States were the two most common destination countries. Most respondents (95/112; 85%) had used donor eggs; half (57/112; 51%) had used more than one surrogate; and the mean number of embryo transfer procedures was 2.9. As a result of surrogacy, 85% (95/112) had at least one child; 55% (62/112) reported that their surrogate had a multiple pregnancy; 10% (11/112) reported that a pregnancy had ended in a late miscarriage or perinatal death; and 45% of births (35/78) were premature. Most respondents (80/112; 71%) were most comfortable with using an identity-release donor, and 87% (97/112) believed that this would also be in their child's best interests. Almost universally, parents were planning to disclose the use of a surrogate and/or a donor to their child.

CONCLUSIONS

Almost half of the intended parents via surrogacy who completed this survey had undertaken compensated surrogacy overseas; most of these used donor eggs, but few considered Australian donors. A high proportion of surrogates had multiple pregnancies and there was a high rate of premature birth. These adverse outcomes could be avoided if the surrogacy was undertaken in Australia. Removing some of the existing barriers to surrogacy in Australia may reduce the number of surrogacy arrangements carried out overseas.

Proposed legislative change mandating retrospective release of identifying information: consultation with donors and Government response

STUDY QUESTION

How do gamete donors who presumed they could remain anonymous respond to proposed legislation to retrospectively remove anonymity?

SUMMARY ANSWER

A little more than half of the donors opposed the recommendation to introduce legislation to remove donor anonymity with retrospective effect.

WHAT IS KNOWN ALREADY

An increasing proportion of parents disclose their origins to their donor-conceived children and growing numbers of donor-conceived adults are aware of how they were conceived. Research indicates that access to information about the donor is important to donor-conceived people. However, worldwide most donor-conceived people are unable to find any identifying information about the donor because of the practice of anonymous gamete donation.

STUDY DESIGN, SIZE, DURATION

This study adopted a qualitative research model using semi-structured interviews with gamete donors that included open questions. Interviews with 42 volunteers were conducted between December 2012 and February 2013.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Before 1998 gamete donors in Victoria, Australia, were able to remain anonymous. Pre-1998 donors were invited through an advertising campaign to be interviewed about their views on a recommendation that legislation mandating retrospective release of identifying information be introduced.

MAIN RESULTS AND THE ROLE OF CHANCE

Donors were almost evenly split between those who supported and those who rejected the recommendation to introduce legislation to remove donor anonymity with retrospective effect. About half of the donors who rejected the recommendation suggested the compromise of persuading donors voluntarily to release information (whether identifying or non-identifying) to donor-conceived people. These donors were themselves willing to supply information to their donor offspring. The findings of this study informed the Victorian Government's response to the proposed legislative change. While acknowledging donor-conceived people's right of access to information about their donors, the Government decided that identifying information should be released only with the consent of donors and that donors should be encouraged to allow themselves to be identifiable to their donor offspring.

LIMITATIONS, REASONS FOR CAUTION

There is no way of knowing whether participants were representative of all pre-1998 donors.

WIDER IMPLICATIONS OF THE FINDINGS

The balancing of donors' and donor-conceived people's rights requires utmost sensitivity. All over the world, increasing numbers of donor-conceived people are reaching adulthood; of those who are aware of their mode of conception, some are likely to have a strong wish to know the identity of their donors. Legislators and policy-makers in jurisdictions permitting anonymous gamete donations will need to respond when these desires are expressed, and may choose to be guided by the model of consultation described in this paper.

Attitudes towards embryo donation in Swedish women and men of reproductive age

BACKGROUND

When performing in-vitro fertilization (IVF), more embryos than needed are often derived. These embryos are usually frozen and stored, but as ruled by Swedish law they have to be discarded after 5 years. In other countries it is legal to donate the excess embryos to other infertile couples who for different reasons cannot undergo the procedure of IVF. The aim of the present study was to investigate public opinion in Sweden regarding different aspects of embryo donation.

METHODS

A questionnaire regarding attitudes towards aspects of embryo donation was sent to a randomized sample of 1,000 Swedish women and men of reproductive age.

RESULTS

A total of 34% responded to the questionnaires. A majority of the respondents (73%) were positive towards embryo donation. Seventy-five per cent agreed that it should be possible to donate embryos to infertile couples. Approximately half of the participants (49%) supported embryo donation to single women. A majority of the participants emphasized that demands should be imposed on the recipient's age (63%), alcohol addiction (79%), drug addiction (85%), and criminal record (67%). Forty-seven per cent of the respondents agreed that the recipient should be anonymous to the donor, and 38% thought that the donor should remain anonymous to the child.

CONCLUSIONS

The results of the present study indicate support for embryo donation among a subset of the Swedish population of reproductive age. If embryo donation were to be allowed in Sweden, strategies for treatment and counselling need to be developed.

A hierarchy of needs? Embryo donation, in vitro fertilisation and the provision of infertility counselling

OBJECTIVE

The aim of the paper is to examine how those working in, using and regulating assisted conception clinics discussed infertility counselling and its provision within the context of embryo donation and in vitro fertilisation.

METHOD

35 participants were recruited for semi-structured, face-to-face interviews. All data were analysed using thematic analysis.

RESULTS

The thematic analysis revealed recurring themes based upon the portrayals of infertility counselling, embryo donation and in vitro fertilisation.

CONCLUSIONS

This paper suggests that an implicit hierarchy exists around those using assisted conception techniques and their infertility counselling requirements, which was dependent upon the assisted conception technique used. As a result, some people using assisted conception techniques felt that their needs had been overlooked due to this covert hierarchy.

PRACTICE IMPLICATIONS

Those working in, using or regulating assisted conception clinics should not view infertility counselling as restricted to treatments involving donation, or solely for people within the clinical system.

Theoretical and experimental basis of oocyte vitrification

In the last decades significant advances have been made in successful cryopreservation of mammalian oocytes. Human oocyte cryopreservation has practical application in preserving fertility for individuals at risk of compromised egg quality due to cancer treatments or advanced maternal age. While oocyte cryopreservation success has increased over time, there is still room for improvement. Oocytes are susceptible to cryodamage; which collectively entails cellular damage caused by mechanical, chemical or thermal forces during the vitrification and warming process. This review will delineate many of the oocyte intracellular and extracellular structures that are/may be stressed and/or compromised during cryopreservation. This will be followed by a discussion of the theoretical basis of oocyte vitrification and warming, and a non-exhaustive review of current experimental data and clinical expectations of oocyte vitrification will be presented. Finally, a forward-thinking vision of a potential means of modifying and improving vitrification and warming procedures and success will be proposed. This review addresses theoretical and experimental evidence accumulated over the last two decades supporting the application of vitrification and warming to oocyte cryopreservation. Issues ranging from clinical needs for oocyte cryopreservation, cryopreservation-induced stresses and normal oocyte function, practical application of vitrification-warming of oocytes, and potential future directions will be discussed. In addition, we debate commonly discussed technical methods of oocyte vitrification-warming that may not necessarily be grounded in scientific knowledge. Instead these methodologies are many times theoretical, potentially empirical and commonly lack significant testing and scientific rigor. Questions include: (i) what is the best cryoprotectant? (ii) are some cryoprotectants more toxic compared with others? (iii) how should cryosolutions be mixed with cells? (iv) is there a best container for vitrification? (v) is there a threshold cooling-warming rate or is a faster rate always better? and finally (vi) should oocytes be vitrified with or without adjacent cells? With this said, it is recognized that important advancements have been made in the past decade in oocyte cryopreservation, many times through empirical findings. Finally, we propose some new areas of research that may influence future success of oocyte vitrification and warming, fully recognizing that these theories require mechanical and biological experimental testing.

Two decades after legislation on identifiable donors in Sweden: are recipient couples ready to be open about using gamete donation?

BACKGROUND Two decades after the introduction of Swedish legislation that allows children born as a result of gamete donation access to identifying information about the donor, a nationwide multicentre study on the psychosocial consequences of this legislation for recipients and donors of gametes was initiated in 2005. The aim of the present study was to investigate recipient couples' attitudes and behaviour regarding disclosure to offspring and others, attitudes towards genetic parenthood and perceptions of information regarding parenthood after donation. METHODS The present study is part of the prospective longitudinal 'Swedish study on gamete donation', including all fertility clinics performing donation treatment in Sweden. A consecutive cohort of 152 heterosexual recipient couples of donated oocytes (72% response) and 127 heterosexual recipient couples of donated sperm (81% response) accepted participation in the study. In connection with the donation treatment, male and female participants individually completed two questionnaires with study-specific instruments concerning disclosure, genetic parenthood and informational aspects. RESULTS About 90% of participants (in couples receiving anonymous donated gametes) supported disclosure and openness to the offspring concerning his/her genetic origin. Only 6% of all participants had not told other people about their donation treatment. Between 26 and 40% of participants wanted additional information/support about parenthood following donation treatment. CONCLUSIONS Two decades after the Swedish legislation of identifiable gamete donors, recipient couples of anonymously donated sperm and oocytes are relatively open about their treatment and support disclosure to offspring. Recipient couples may benefit from more information and support regarding parenthood after gamete donation. Further studies are required to follow-up on the future parents' actual disclosure behaviour directed to offspring.

Anonymity and secrecy options of recipient couples and donors, and ethnic origin influence in three types of oocyte donation

BACKGROUND

This study compares recipient couples' and donors' motivations towards the type of donation and attitudes concerning secrecy or disclosure of the mode of conception in three oocyte donation groups: couples and their donor for a known donation, couples and their donor for a permuted anonymous donation (known-anonymous) and couples without a donor, on a waiting list for a donation (anonymous).

METHODS

Data collected by two psychologists through semi-structured interviews of 135 recipient couples and 90 donors before oocyte donation were analysed retrospectively.

RESULTS

In known donation (42 couples), donors were preferentially family members with a blood tie (54.7%). Choosing their donor seemed mainly for the couple's reassurance rather than to access the child's origins as 50% wanted secrecy. On the other hand, in known-anonymous donation (48 couples), donors were more frequently chosen among friends (41.6%; P = 0.038). These couples were either open to disclosure (45.8%; P = 0.002) or remained hesitant (39.6%). In anonymous donation (45 couples), 49% chose not to seek a donor mostly in order to maintain secrecy towards the child (77.3%). Among the 51% who sought but could not find a donor, only 30.4% wanted secrecy. Recipients from North Africa and from Europe preferred anonymous or known-anonymous donation (83.3 and 75.6%), whereas sub-Saharan Africans opted more often for known donation (63%; P < 0.001). Among Europeans (90 couples), 50% were in favour of disclosure compared with only 8.9% of recipients from North or sub-Saharan Africa (45 couples; P < 0.001).

CONCLUSIONS

A diversity of attitudes and cultural differences exist among recipient couples and donors regarding oocyte donation; this pleads for maintaining access to different types of oocyte donation as well as for psychological counselling prior to treatment.

Prospective randomized comparison of human oocyte cryopreservation with slow-rate freezing or vitrification

OBJECTIVE

To compare cryopreservation of mature human oocytes with slow-rate freezing and vitrification and determine which is most efficient at establishing a pregnancy.

DESIGN

Prospective randomized.

SETTING

Academically affiliated, private fertility center.

PATIENT(S)

Consenting patients with concerns about embryo cryopreservation and more than nine mature oocytes at retrieval were randomized to slow-rate freezing or vitrification of supernumerary (more than nine) oocytes.

INTERVENTION(S)

Oocytes were frozen or vitrified, and upon request oocytes were thawed or warmed, respectively.

MAIN OUTCOME MEASURE(S)

Oocyte survival, fertilization, embryo development, and clinical pregnancy.

RESULT(S)

Patient use has resulted in 30 thaws and 48 warmings. Women's age at time of cryopreservation was similar. Oocyte survival was significantly higher following vitrification/warming (81%) compared with freezing/thawing (67%). Fertilization was more successful in oocytes vitrified/warmed compared with frozen/thawed. Fertilized oocytes from vitrification/warming had significantly better cleavage rates (84%) compared with freezing/thawing (71%) and resulted in embryos with significantly better morphology. Although similar numbers of embryos were transferred, embryos resulting from vitrified oocytes had significantly enhanced clinical (38%) pregnancy rates compared with embryos resulting from frozen oocyte (13%). Miscarriage and/or spontaneous abortion rates were similar.

CONCLUSION(S)

Our results suggest that vitrification/warming is currently the most efficient means of oocyte cryopreservation in relation to subsequent success in establishing pregnancy.

An overview on ethical issues about sperm donation

Beyond the scientific progress in assisted reproductive technologies (ART), it is necessary to discuss the ethical considerations behind these advances. Ethical issues concerning sperm donation have been considered and discussed by government and non-governmental agencies, the public, media and academic institutions in many countries. Recommendations and guidelines concerning sperm donation issues vary from country to country and between professional groups within countries. This paper attempts to present an overview of findings and reports from various agencies concerning the ethics of sperm donation. The following topics are considered: limiting the number of donor offspring; minimizing risk of infection and genetics from sperm donors; age requirements for sperm donors; and anonymity versus non-anonymity of sperm donors. The diversity of policies shows that each country has its unique set of guidelines tailored toward its own specific needs. Similarly, countries designing their own procedures and guidelines concerning reproductive medicine must tailor them toward their own needs and practical considerations. In Mainland China, the anonymous policy for sperm donation should still be carried out, and the number of donor offspring should be revaluated. ART procedures must be conducted in a way that is respectful of those involved. Ethical principles must respect the interests and welfare of persons who will be born as well as the health and psychosocial welfare of all participants, including sperm donors.
