The choice between an open-identity (willing-to-be-known) donor and an anonymous donor is one of the most consequential decisions in assisted reproduction — not just for the intended parent but for the child who will grow up with the consequences of that decision. This guide examines what the evidence shows, what donor-conceived adults say, and how to weigh the factors that matter most.
The Case for Open-Identity Donors
Open-identity donors (also called ID-release or willing-to-be-known donors) agree to allow the sperm bank to release their identity to any donor-conceived offspring who request it at age 18. This arrangement — increasingly the default at many leading sperm banks — gives donor-conceived people the option of knowing who their donor is without obligating contact if they choose not to pursue it. The asymmetry is important: an open-identity donor arrangement always preserves the option of contact; an anonymous arrangement permanently forecloses it.
Survey data from donor-conceived adults consistently supports this asymmetry. Multiple studies of donor-conceived adults find that 60–80% express curiosity about their donor’s identity, and a significant subset describe distress about the impossibility of knowing an anonymous donor’s identity. A landmark 2006 study by Joanna Scheib found that donor-conceived adolescents (ages 12–17) with identity-release donors reported greater psychological adjustment and more positive family communication than those with anonymous donors, independent of other family variables. The American Society for Reproductive Medicine’s 2021 ethics committee report acknowledged that anonymous donation creates harms to donor-conceived people that should weigh in family formation decisions.
Practical Realities of ‘Anonymous’ Donation in the DNA Age
The practical reality of anonymous donation has been fundamentally changed by direct-to-consumer DNA testing. Commercially available DNA tests (23andMe, AncestryDNA) make it possible for donor-conceived people to identify half-siblings and often to identify donors through family networks — even when the donor registered as anonymous with the sperm bank. Genetic genealogist Cece Moore and others have demonstrated that connecting a DNA test result to an identity is achievable for most donors who have any relatives who have tested, which in a population of 330 million Americans means a substantial fraction of anonymous donors are now de facto identifiable.
The implication is that ‘anonymous’ donation no longer reliably guarantees anonymity — it only determines whether the sperm bank will facilitate identification. A donor-conceived person motivated to find their donor will likely be able to do so using consumer DNA tools regardless of the donation’s official anonymity status. Parents choosing anonymous donors should do so with this reality in mind: the decision is less about whether the child will ever be able to find the donor and more about whether the family has an official, bank-facilitated pathway for that connection. Choosing anonymous donation while expecting true anonymity to hold may set the stage for a disclosure moment that is more complicated than a family with an open-ID donor would face.
Arguments for Anonymous Donation
The arguments for anonymous donation are not without merit and deserve honest representation. Some donors are willing to donate only if anonymity is guaranteed — meaning that a fully open-ID-only policy would reduce the donor pool and potentially reduce diversity of available donors. Anonymous donors represent a significant share of the current supply, particularly for popular historical donors whose specimens may still be available from stored lots. Families who have already used anonymous donors should not be made to feel they have harmed their child — the research shows outcomes depend far more on parenting quality and disclosure openness than on donor identity release status.
Additionally, some families — including families in cultures or communities where donor conception carries stigma — may have legitimate privacy interests in anonymous donation that affect family safety or social functioning. The individual family’s specific circumstances matter in this decision, and ethical reasoning that ignores context in favor of absolute principles risks failing the very families it intends to serve. The goal is to make the most informed decision possible with full awareness of the evidence, not to produce mandatory conclusions that override individual circumstances.
Making Your Decision
The most evidence-aligned recommendation for families who have genuine freedom to choose is to select an open-identity donor or at minimum a donor who has agreed to future contact facilitated by the sperm bank or a mutual consent registry. This choice preserves options for your child in ways that anonymous donation does not, without obligating contact that neither party wants. When an open-identity donor of the right profile is not available, choosing the most information-rich anonymous profile available — one with a detailed family health history, personal essay, audio interview, and professional photo — minimizes the information deficit that donor-conceived people often describe as their primary source of distress.
Whatever donor type you choose, your ongoing conversation with your child about their origins, your openness to their questions, and your willingness to support their curiosity (including potential future contact with a donor or half-siblings) matters more to their long-term identity development than the initial anonymity decision. Parents who are emotionally open to their child’s donor-related curiosity — who support rather than fear their child’s interest in genetic heritage — produce better outcomes than parents who restrict information but chose an open-identity donor. The choice of donor type and the parenting approach to donor-conceived identity are both important; the parenting approach is consistently more powerful.
