One size does not fit all: the personal nature of completed embryo donation.

Purpose: To assess factors associated with embryo donation among individuals interested in donation in the United States.

Methods: An invitation to complete the 123-item survey was emailed from June to September 2022 to patients at a private practice fertility clinic with interest in donation at the time of IVF. Survey questions included disposition decision, attitudes about embryo status and genetic relatedness, donation disclosure, ideal donation arrangement, and decision satisfaction.

Results: Three hundred thirty-seven completed the survey. Two hundred thirty donated to another person(s), 75 discarded embryos, 25 remained undecided, and disposition was unknown for 7 respondents. There were no demographic differences between groups based on final disposition or use of donor gametes. Few gamete recipients were interested in donation due to biological attachment to embryos. Final embryo disposition was associated with religious factors, not wanting to waste embryos, and storage fee concerns. Final disposition was also significantly associated with concern about donor-conceived children's (DCP) welfare, being denied the ability to complete donation, personal IVF outcomes, financial or legal issues, future contact with DCP, cognitive appraisal of disposition, beliefs about embryos, someone else raising their genetic child, anonymity, and beliefs about DCP not knowing genetic relationships (p < .001). Donation to others was associated with less regret and greater satisfaction with the emotional/medical aspects of donation and counseling compared to those who discarded embryos (p < .001).

Conclusion: The decision to donate embryos to another person(s) is complex. Counseling that considers individual circumstances, values, and evolving dynamics may facilitate informed decision-making for those navigating infertility treatment, family building, and embryo disposition.
