Comparative assessment of pre- and post-donation attitudes towards potential oocyte and embryo disposition and management among ovum donors in an oocyte donation programme.

BACKGROUND: In anonymous oocyte donation programmes, the disposition of retrieved oocytes and subsequent embryo management are at the discretion of the IVF programme and the oocyte recipients, as donors waive all rights following their donation. Nonetheless, donors are routinely made aware of ways in which oocytes and resulting embryos may be used and elect to proceed with the process even in the presence of reservations to some clinical scenarios before their donation. The aim of our study was to examine oocyte donors' attitudes to oocyte and embryo disposition and management and how initial reservations change over the course of the donation process. METHODS: Oocyte donors in a university-based IVF programme were asked about their willingness to donate in relation to various clinical scenarios during the initial screening interview and at the post-donation exit interview. Results were tabulated as 'yes' or 'no'. RESULTS: At the pre-donation interview, 72% of donor candidates expressed reservations to one or more clinical scenarios. More reservations were expressed at the post-donation interview compared with the pre-donation interview. The greatest reservations were donating to recipients >50 years of age (P < 0.05). Despite this, 97% of donors were willing to donate again. CONCLUSION: Oocyte donors' attitudes towards various clinical scenarios changed following their donation, reflecting overall greater reservations following the donation process. Although speculative, donors may be more willing to assert their opinions or donor attitudes become more restrictive.

Embryo disposition: the forgotten "child" of in vitro fertilization.

Cryopreservation of embryos is frequently employed in in vitro fertilization (IVF) practices because transfer of more than 3 embryos per cycle is not advantageous, and cryopreserved embryos offer fairly high pregnancy rates upon eventual transfer. Unfortunately, frozen embryos accumulate (approximately 4 per cycle). Thus, industrialized countries have developed laws or guidelines to govern their disposition, which may be disposal, or donation to medical research or to a recipient infertile couple. Worldwide, national regulations vary from eternal preservation to 10-year and 5-year preservation limits. The attitudes of couples who have undergone IVF range from almost parental concern for the embryos to regarding them as medical by-products--with little relationship to a couple's having a living child, in most studies. This paper describes disposition studies in various countries and couples' actions taken at time of disposition, with special detail on the problems involved in embryo donation to another couple.

Factors that affect infertility patients' decisions about disposition of frozen embryos.

OBJECTIVE: To describe factors that affect infertility patients' decision making regarding their cryopreserved embryos. DESIGN: Forty-six semistructured in-depth interviews of individuals and couples participating in IVF programs. SETTING: Two major southeastern academic medical centers. PATIENT(S): Fifty-three individuals, including 31 women, 8 men, and 7 couples. MAIN OUTCOME MEASURE(S): Qualitative analysis of interview transcripts. INTERVENTION (S): None. RESULT(S): Seven broad themes informed participants' decisions about embryo disposition: family and personal issues, trust, definition of the embryo, prospective responsibility to the embryo, responsibility to society, adequacy of information, and lack of acceptable disposition options. Many wished for alternative options, such as a ceremony at the time of disposal or placement of embryos in the woman's body when pregnancy was unlikely. CONCLUSION(S): Recent debates regarding embryo disposition do not reflect the range of values that infertility patients consider when deciding about frozen embryos. In addition to questions about the embryo's moral status, decision making about embryos is informed by a range of factors in the lives of individuals who created them. These perspectives may have important implications for the content and timing of informed consent, facilitating embryo disposition, and advancing policy debates about the ethics of frozen embryo use.

Determining access to assisted reproductive technology: reactions of clinic directors to ethically complex case scenarios.

BACKGROUND: Our aim was to increase understanding of how patient selection is handled by assisted reproductive technology (ART) clinicians. METHODS: Ethically complex case scenarios were evaluated by the directors of USA ART clinics. Scenarios included using a son as sperm donor for his father, sex selection without associated disease, treatment of morally irresponsible couples, and a dispute over embryo disposition. Respondents reviewed eight scenarios and gave their opinions on whether to offer treatment. Reasons given for these decisions were placed into one of 13 categories. RESULTS: Survey response rate was 57%. Between 3 and 50% of respondents would treat in each case. Of reasons given, 'conditional' responses (requiring counselling, blood tests or agreement to other 'conditions') were common (31.4%). Non-maleficence (risk) accounted for 29.4% of responses, philosophy of medicine 18.9%, respect for patient autonomy 5.9% and legal concerns 4.6%. Discrimination and threats were each significant in one case. Reasons evoking absolutist beliefs, personal discomfort, commitment to justice, religion and ethical relativism were rare. CONCLUSIONS: Clinicians felt conflict between a desire to respect patient autonomy and their discomfort over the risk associated with the procedure. They raised concerns about misuse of medical technology. Attempts to resolve complex issues through negotiation and compromise were common.

Assessment of wishes regarding disposition of oocytes and embryo management among ovum donors in an anonymous egg donation program.

Revealing possible clinical scenarios to potential anonymous donors for their donated oocytes appears to uncover ambivalence in the majority of prospective candidates about their donation and unwillingness in some to proceed. Full disclosure to a prospective donor candidate of the program's policies for directives of donated oocytes and embryo management emphasizes the importance of the informed consent process and how it may affect the decision to donate.

Parents' conceptualization of their frozen embryos complicates the disposition decision.

OBJECTIVE: To ascertain what couples think about their embryos and how they approach making a decision about disposition in light of the fact that the disposition of unused frozen embryos has significant implications for medical research and embryo donation. DESIGN: Ethnographic qualitative interview study. SETTING: Academic research environment. PATIENT(S): Fifty-eight couples who had conceived using a donor oocyte and had at least one frozen embryo in storage. MAIN OUTCOME MEASURE(S): Tape-recorded interviews with 58 wives and 37 husbands were transcribed and analyzed for emergent themes. RESULT(S): With an average of 7.1 embryos per couple, after an average of 4.2 years of storage, 72% of couples with frozen embryos had not reached a disposition decision. Most couples had not anticipated or appreciated the consequences of having surplus embryos. Parents variously conceptualized frozen embryos as biologic tissue, living entities, "virtual" children having interests that must be considered and protected, siblings of their living children, genetic or psychological "insurance policies," and symbolic reminders of their past infertility. CONCLUSION(S): The disposition decision is not only a significant and frequently unresolved issue for couples with stored frozen embryos, but their deeply personal conceptualizations of their embryos contributes to their ambivalence, uncertainty, and difficulty in reaching a decision.
