What constitutes a reasonable compensation for non-commercial oocyte donors: an analogy with living organ donation and medical research participation

Advances in three-dimensional printing of hydrogel formulations for vascularized tissue and organ regeneration

Over the last decades, three-dimensional (3D) printing has emerged as one of the most promising alternative tissue and organ regeneration technologies. Recent advances in 3D printing technology, particularly in hydrogel-derived bioink formulations, offer promising solutions for fabricating intricate, biomimetic scaffolds that promote vascularization. In this review, we presented numerous studies that have been conducted to fabricate 3D-printed hydrogel vascularized constructs with significant advancements in printing integumentary systems, cardiovascular systems, vascularized bone tissues, skeletal muscles, livers, and kidneys. Furthermore, this work also discusses the engineering considerations, current challenges, proposed solutions, and future outlooks of 3D bioprinting.

Personal interest and attitudes towards oocyte donation practice: a cross-sectional survey among Dutch-speaking young women in Belgium

PURPOSE

This survey aimed to assess the public's knowledge and opinions on oocyte donation (OD) among a large, unselected cohort of young Belgian women, and to explore aspects that could be enhanced to promote future OD programs.

METHODS

We conducted a quantitative, epidemiological, cross-sectional web-based survey from February 2023 to April 2023. A private questionnaire was distributed to young women (21-30 years) living in Belgium via a digital link. The survey covered socio-demographic characteristics, knowledge about the OD procedure, compensation, personal attitudes, motivations and perceptions about anonymity assurance.

RESULTS

A total of 390 women responded to the online questionnaire, with a drop-out rate of 10%. The survey revealed a good level of knowledge about the procedural aspects of OD, which did not influence willingness to donate. Only 19% of respondents were willing to donate, while 39.1% hesitated, particularly regarding private OD. No significant association was found between personal values and willingness to donate. Altruism emerged as the main motivation for gamete donation. Attitudes towards anonymity varied, with childless and older individuals more reluctant to reveal their identity.

CONCLUSIONS

Our study confirms that a small portion of the population is willing to donate oocytes, while a considerable proportion (39%) is hesitating. These findings highlight the urgent need for global education programs to raise awareness and address concerns that may prevent women from participating in OD programs.

Oocyte donors' experience and expectations in a non-profit fertility care setting

PURPOSE

In this survey, we aimed to provide the description of previous oocyte donors' profile in a Belgian tertiary fertility hospital clinic. The research question is as follows: could certain aspects be changed or improved, according to previous oocyte donors? The final purpose is to boost adherence to future oocyte donation (OD) programs, given the large gap between supply and demand.

METHODS

We set up an observational cross-sectional study of oocyte donors who were recruited in a tertiary referral hospital. Participants were asked to join an anonymous online survey with questions about demographic and reproductive variables, reasons to start or discontinue OD, satisfaction rate, experience, and attitude towards presumed anonymity.

RESULTS

A total of 218 women were eligible to join the study, with a response rate of 49% (108/218). The emerging profile of the oocyte donor is a well-educated (102/108 with at least a high school degree), employed (86/108) woman in her thirties. Altruism and solidarity were the main drivers of their choice (105/108), and a general permissive attitude towards disclosure of their personal information to the recipient (60/108) was registered. In case of negative experience or discontinuation, concerns regarding pain management and specific long-lasting psychological support were expressed (8/20).

CONCLUSIONS

Our findings suggest the need to improve pain relief and to offer psychological support even beyond ending the donation process. These interventions could improve both participation and adherence to OD programs, ensuring an autonomous and free choice while avoiding any risk of exploitation.

Fertility stakeholders' concerns regarding payment for egg and sperm donation in New Zealand and Australia

New Zealand and Australia are countries which currently prohibit donor payment and require open-identity forms of donation. This study explored the concerns of fertility stakeholders regarding payment which would constitute financial reward for gamete donation, and factors predicting such concerns. A total of 434 participants from across New Zealand and Australia completed an online survey anonymously. Participants included those with infertility and treatment experience, donors, recipients, donor-conceived people and clinic professionals. Results indicated that participants' concerns related to their assumptions about the type of donor motivated by financial reward, and the possibility that, if paid, donors might conceal information relevant to treatment and the donor-conceived person. Furthermore, participants were concerned about increasing recipient costs. Participants with personal experience of infertility held stronger concerns overall. Professionals expressed concerns of clinical relevance, such as the withholding of donor information relevant to treatment outcomes. The lowest levels of concern were expressed in relation to payment devaluing the meaning of human life. Qualitatively, themes highlighted concerns regarding payment enticing the 'wrong' type of donor, increased cost to recipients, and concern about the wellbeing of donor-offspring. Collectively, such concerns must be understood against the New Zealand and Australia open-identity donation context which enables the possibility of contact between donors and offspring. These findings indicate that donor recruitment campaigns need to account for different stakeholder concerns, and consider ways to address donor shortages effectively while remaining compliant with legislative requirements.

Motivations for egg donation to previously unknown recipients: donation as a personal, relational act of giving

Egg donation has becoming increasingly common however there is a shortage of donors in many countries, including New Zealand. Research regarding motivations to donate in the context of New Zealand's open-identity and altruistic donation policy and practice is, thus far, limited. This in-depth qualitative study comprised interviews with 21 women to examine their motivations in donating to recipients previously unknown to them. Donors valued parenthood highly and had become aware of the fertility struggles of other women through their own experiences, those of friends or family, or through online personal accounts or advertising. The ability to select recipients and build a comprehensive picture of them, such as through reading recipient profiles or meeting them in person, as is possible in New Zealand, deepened their identification with recipients and thus their empathy and desire to help. They resisted commercial models, positioning themselves as by nature altruistic and regarding their donations as expressions of solidarity and acts of personal gift-giving to specific others who became known to them through donation. Donation was interpreted as a socially relational process, setting up expectations around relationships and ongoing connection. Such understandings have implications for recruitment as well as ongoing experiences and support needs.

Fair allocation of cryopreserved donor oocytes: towards an accountable process

A growing number of people desire ART with cryopreserved donor oocytes. The allocation of these oocytes to couples and mothers to be is a 2-fold process. The first step is to select a pool of recipients. The second step is to decide who should be treated first. Prioritizing recipients is critical in settings where demand outstrips supply. So far, the issue of how to fairly allocate cryopreserved donor oocytes has been poorly addressed. Our ethical analysis aims to support clinics involved in allocation decisions by formulating criteria for recipient selection irrespective of supply (Part I) and recipient prioritization in case supply is limited (Part II). Relevant criteria for recipient selection are: a need for treatment to experience parenthood; a reasonable chance for successful treatment; the ability to safely undergo an oocyte donation pregnancy; and the ability to establish a stable and loving relationship with the child. Recipients eligible for priority include those who: have limited time left for treatment; have not yet experienced parenthood; did not undergo previous treatment with cryopreserved donor oocytes; and contributed to the supply of donor oocytes by bringing a donor to the bank. While selection criteria function as a threshold principle, we argue that the different prioritization criteria should be carefully balanced. Since specifying and balancing the allocation criteria undoubtedly raises a moral dispute, a fair and legitimate allocation process is warranted (Part III). We argue that allocation decisions should be made by a multidisciplinary committee, staffed by relevant experts with a variety of perspectives. Furthermore, the committees' reasoning behind decisions should be transparent and accessible to those affected: clinicians, donors, recipients and children born from treatment. Insight into the reasons that underpin allocation decisions allows these stakeholders to understand, review and challenge decisions, which is also known as accountability for reasonableness.

Mild stimulation should be mandatory for oocyte donation

The increasing commercialization of oocyte donation is a source of concern. This evolution is expressed in the fact that oocyte donors’ interests are not a priority. For decades now, people mention that oocyte donation holds serious health risks for donors, as if this is an unavoidable given. However, most of the harm is caused by high hormonal stimulation. The risk/benefit balance of high stimulation compared to the risk/benefit balance of mild stimulation does not justify causing greater harm to donors, especially given the fact that donors submit to the procedure without any medical benefit for themselves and to help others.
