What 'Anonymous' on an Egg Donor Page Actually Means

A donor’s page says anonymous, and most readers take that as one fact about the donor. It is not one fact. It is an intention held by several parties, a rule that may or may not sit behind that intention, and a prediction about technology that the professional bodies have already stopped making.

This matters more in a surrogacy journey than in a treatment cycle, because you are usually buying a future at the same time: a child who will grow up, ask questions, and live among records kept by organisations that may not exist in twenty years.

The word has already been retired by the people who wrote the guidance

United States professional guidance on gamete and embryo donor terminology asks the field to stop using anonymous and known, and to say nonidentified and directed (identified) instead. The reasoning is stated rather than implied: anonymity was historically protected by clinical protocols and by legislation about who is a legal parent, and social media plus broad access to direct-to-consumer DNA testing mean that expectations of donor anonymity can no longer be assured. The document’s own summary is blunter: the era of perpetual donor anonymity has ended.

Two consequences follow for anyone reading a catalogue.

The stricter category is the anonymous one. A donor who is judged ineligible on infectious or genetic grounds cannot have their tissue used for a non-directed donation at all. In a directed donation, where the parties know each other, the same tissue may be used provided both sides understand the risk and consent to it. So a page advertising nonidentified donors is offering you tissue that cleared a higher bar, and a known donor is not automatically the safer choice it reads as.

Traceability does not depend on your donor. The guidance records that donors and donor-conceived people may be findable even if they never submit DNA themselves, because a relative with a genetic link may be in a database. It estimates tens of millions of Americans have genetic information held in privately owned and largely unregulated databases, and it notes facial recognition has become markedly more accurate. Its worked example is mundane rather than exotic: two families, neither of whom disclosed anything, each send a sample to a consumer service, and both are told a half-sibling has appeared.

What a law gives depends on a year of birth

The United Kingdom shows how much the guarantee varies inside one country. The Nuffield Council on Bioethics sets out the position as of 2023: the Human Fertilisation and Embryology Authority keeps a register of donor conception procedures, and a person born from donated gametes used in a licensed clinic can apply for identifying information about their donor at 18. That rule came into force in 2005, so it reaches the people born from that year onward.

Two groups sit outside it. People conceived before 2005 have no access to identifying information unless the donor chooses to make themselves identifiable. And before 1991, when statutory regulation of fertility treatment began, no information was held centrally at all; the record for those donations is very limited or absent. The register the HFEA funds for that cohort, the Donor Conceived Register, works by voluntary DNA matching rather than by entitlement.

Read as a lesson rather than as a summary of British law, that history says: the rule you contract under is a rule of a moment, and the child you are planning for will be governed by whatever the rule has become by the time they can use it. It also says something practical about destination research, which the destination checklist is built around. A donor information regime is not one fact but several, and one of them is from which year.

What a contract can actually commit

Between the intention and the law sits the document. The terminology guidance describes nonidentified as the shared intention of everyone involved, including the clinic or bank, not to exchange identifying information, and it says that intention holds only so far as the law allows, or to whatever explicit and limited degree the paperwork states.

That second half is where useful detail lives. The guidance notes that a consent or contract may allow contact to be arranged between a donor-conceived person and their donor once the child reaches a stated age, often the age of majority, and that those arrangements are what open-identity means. So there are at least three quite different arrangements on offer: an intention with no written mechanism; a contract that arranges contact at a stated age; and a jurisdiction whose register will hand over identifying information if the child applies.

Which one you choose changes what you can tell a future child. The gamete donation guidance answers the part of that question you can put directly: it recommends that a donor’s consent cover a future request for follow-up testing or medical information arising from a diagnosis in a donor-conceived child. That is a concrete promise you can request in writing, and it is worth more than a photograph of the donor as a teenager. The same guidance asks for a detailed three-generation family history from every donor so far as possible, and says a donor who was adopted and cannot supply one should be considered case by case. Ask which of those two situations your donor’s page is actually describing.

Three things to have in writing

1. Which category applies to this donor. Nonidentified in intention only, or a contract that arranges contact at a stated age, or an identifiable donor under a register. Ask for the word the paperwork uses, not the word on the page.
2. Whether the donor consented to future medical information requests, and what the bank or clinic will do if a health condition appears in a donor-conceived child.
3. Who holds the records and for how long, and what happens to them if the clinic or bank stops operating. Ask whether the same answers appear in your contract and in the donor’s consent, and compare them; the carrier-side guide covers where those holdings usually sit.

What no donor document settles

Nothing here decides parentage, and no donor document tells you how many families this donor’s gametes have already been used for. The information regime you are buying into is set by a destination’s law as much as by a provider’s paperwork, which is why it belongs in the six dimensions a destination page should answer rather than in a message from a sales team.

What is set out above follows published guidance and a 2023 policy record, with their dates. It is not legal advice, and the rules that apply to your child may have been written after those were.
