Identity-release donor programs are sperm and egg donation arrangements in which the donor agrees, at the time of donation, that their name and contact details will be shared with any resulting child once that child turns eighteen. The model sits between fully anonymous donation and a known-donor arrangement: the family has privacy during the child’s early years, and the child has a path to biological connection later. The donor takes on no parental rights and no financial obligations as a result of that future disclosure.
How the Arrangement Works
When a donor enrolls at a sperm bank or egg donation agency, they choose whether to donate anonymously or as an identity-release donor (sometimes called “open identity” or “open ID”). Choosing identity-release means the donor consents to at least one form of contact with any child born from their gametes after that child turns eighteen. The choice is generally permanent. Most programs do not allow an identity-release donor to switch back to anonymous status once enrolled.
The child, not the donor, controls whether contact ever happens. Donors never receive the names or identities of the families who used their gametes. When a donor-conceived adult asks for the information, the clinic or sperm bank facilitates a connection using whatever method both sides agree to, whether that is a phone call, a written exchange, or a meeting in person. Neither side is obligated to maintain an ongoing relationship. After the initial contact, the donor can engage further or decline.
What the Donor Puts on File
At enrollment the donor completes a registration package that becomes the permanent record for any future disclosure. Under the Uniform Parentage Act 2017 framework, “identifying information” means the donor’s full name, date of birth, and current address, phone number, and email.1Uniform Parentage Act (2017). Uniform Parentage Act 2017 Final Act Beyond those basics, clinics collect a detailed medical history covering current and past illnesses and the donor’s social, genetic, and family health background.
Because eighteen or more years will pass before anyone asks for the file, keeping it current is a real challenge. Most programs ask donors to sign a periodic update agreement committing them to notify the registry of changes in contact information and new health developments. Some registries charge a modest administrative fee for processing those updates. A donor who moves, changes phone numbers, or develops a new medical condition without updating the registry can render the file useless at the moment it matters most. Good intentions at twenty-two do not guarantee cooperation at forty.
Clinics and gamete banks store these records in secure databases, sometimes maintained by specialized third-party registries. They must be preserved far longer than typical medical files. Facilities operating under the UPA 2017 framework take on a formal, ongoing obligation to maintain and eventually disclose them.
How a Donor-Conceived Adult Requests the Information
The disclosure process starts when the donor-conceived person turns eighteen and contacts the clinic or gamete bank that handled the original donation. The request is typically submitted in writing with notarized proof of identity.2Fertility and Sterility. Who Requests Their Sperm Donors Identity – The First Ten Years of Information Releases to Adults With Open-Identity Donors The clinic matches the applicant to the correct donor file and confirms that the donor authorized the release of identifying information.
Timelines vary. Some disclosures resolve within a day, others stretch beyond a year, depending largely on how easily the clinic can verify the donor’s current contact details and how promptly the donor responds to outreach.2Fertility and Sterility.

At minimum, the requesting adult receives the donor’s full name, last known contact information, and date and place of birth. If the donor has filed updates over the years, the record may also include recent medical history or personal details. Before releasing the information, most programs walk the requesting adult through a final conversation covering what to expect, the donor’s known openness to contact, confidentiality considerations, and support resources in case the experience proves emotionally complicated.
Parents of a minor cannot access identifying information before the child turns eighteen, but they can separately request nonidentifying medical history at any time.
When the Donor Cannot Be Found
Programs depend on donor cooperation. If a donor has moved, changed contact information, and never updated the registry, the clinic may not be able to deliver on the promise of identity release. In that situation the clinic typically provides whatever identifying information it has on file, even if outdated, but cannot guarantee a live connection. This is one reason at-home DNA testing has become a parallel path for donor-conceived people: it does not depend on the donor having kept a registry current.
Voluntary Registries
Not every connection happens through the original clinic. The Donor Sibling Registry, founded in 2000, operates as an independent platform where donors, donor-conceived individuals, and half-siblings can register using their donor number and find genetic relatives. Some egg donation clinics and agencies now reference the registry in their contracts, allowing families and donors to connect before the child turns eighteen if both sides consent.
Voluntary registries fill a gap formal programs were never designed to cover. They allow half-siblings conceived at different clinics using the same donor to find one another. For donor-conceived people whose programs closed or lost records, a voluntary registry combined with DNA testing may be the only viable path to biological relatives.
The Donor’s Legal Status: No Parental Rights, No Support Obligations
The biggest concern donors raise about identity-release is whether disclosure could later lead to a custody claim or child support obligation. Under the Uniform Parentage Act 2017, Section 702 states that a donor is not a parent of a child conceived by assisted reproduction.1Uniform Parentage Act (2017). Uniform Parentage Act 2017 Final Act That status does not change when the donor’s identity is revealed. The law treats the donor as a legal stranger to the child even after the child learns the donor’s name and address.
Disclosure does not create rights to custody or visitation for the donor, and it does not create an obligation to pay child support. These protections are typically reinforced through waivers signed during the initial donation process, spelling out that the release of information is for identity purposes only and does not alter anyone’s legal status. The intended parent-child relationship formed at birth takes priority over the biological connection revealed later.
Estate Planning Is a Real Exception
Contract provisions in a donor agreement cannot bind the donor-conceived child, because the child is not a party to the contract.3American Society for Reproductive Medicine. Gamete Donation – Legal Professional Group This matters most for inheritance. Many estate laws were written before modern reproductive technology, and a donor who dies without a will can produce intestacy outcomes nobody intended. A donor-conceived person who has been legally identified as the genetic offspring of the donor may, depending on the jurisdiction, have a colorable claim to the donor’s estate if no will or trust addresses the issue.
Both donors and intended parents benefit from having estate planning documents in place. For donors, a will or trust that clearly addresses the existence of donor-conceived offspring eliminates ambiguity. For intended parents, estate documents keep the child’s inheritance rights flowing through the intended family rather than through a biological link the donor never meant to create. The ASRM recommends finalizing these documents early rather than treating them as an afterthought.3American Society for Reproductive Medicine. Gamete Donation – Legal Professional Group
The Legal Framework and Where It Applies
The Uniform Parentage Act 2017 is the most comprehensive legal scaffolding for identity-release programs, but it is a model law, meaning states adopt it in whole, in part, or not at all. Article 9 governs donor information specifically. Section 903 requires licensed gamete banks and fertility clinics to collect the donor’s identifying information and medical history at the time of donation. Section 905 then requires those facilities to release that identifying information to the donor-conceived person once they turn eighteen and request it.1Uniform Parentage Act (2017). Uniform Parentage Act 2017 Final Act
In states that have not adopted the UPA 2017 or its Article 9 provisions, the enforceability of an identity-release agreement depends largely on contract law and the policies of the individual clinic. The strength of a donor’s promise to be identifiable therefore varies with where the donation occurred and which facility handled it.
Why Anonymous Donation Is Fading
Anonymous gamete donation is disappearing, both by law and by technology. Sweden banned anonymous donation in 1984. The United Kingdom and New Zealand followed in 2005, Ireland in 2015, Portugal in 2018, and France in 2022. In the United States, Colorado became the first state to prohibit anonymous gamete donation entirely, with the ban taking effect January 1, 2025. The Colorado law also caps any single donor at twenty-five recipient families worldwide and requires gamete banks to update donor records with new health information at least every three years.
Even where anonymous donation remains legal, consumer DNA testing has made true anonymity nearly impossible. Services that build genetic family networks can match a donor-conceived person with the donor’s relatives, effectively identifying the donor without any clinic involvement. One survey of donor-conceived individuals found that seventy-eight percent had successfully identified their donor through consumer DNA testing alone. As the practical difference between “anonymous” and “identifiable” shrinks, many donors have moved to identity-release programs voluntarily.
Family Limits Per Donor
Identity-release programs raise a practical question that anonymous donation obscured: how many half-siblings might a donor-conceived person eventually discover? Industry practice at major sperm banks typically caps usage at twenty-five families per donor within the United States, with separate country-specific limits for international distribution that can be much lower. Some jurisdictions have begun writing these caps into law rather than leaving them to industry self-regulation. The limits exist partly to reduce the genetic risks of concentrating half-siblings in one geographic area, and partly to keep the family networks that identity-release makes visible from growing to a size no one anticipated.
