At European Sperm Bank, new donors can no longer choose to become No-ID Release. We only accept ID Release donors, today. We do have sperm straws from No-ID release donors in stock., Therefore, donor anonymity is still an option for some aspiring parents, depending on local regulations.
ID Release and No-ID Release are now widely accepted terms and the preferred choice for official use. However, many people are accustomed to other terms, such as open donor (for ID Release) and anonymous donor (for No-ID Release). We have used the terms interchangeably in this guide.
An anonymous sperm donor (No-ID Release) is a donor who decides that no personal information or identifying details will ever be revealed or shared with individuals conceived using their donated sperm. With anonymous sperm donation, the donor consents to clear boundaries for the future and understands and agrees that there will be no future contact with donor-conceived children or adults.
Donor anonymity does not mean that all donor information is withheld. Donor profile information will always be available, as it enables aspiring parents to make an informed decision. Though the nature of this data will vary from sperm bank to sperm bank, it should only contain non-identifying info. For instance, at European Sperm Bank, donor attributes on profiles include:
In some cases, the profile may also include baby photos, handwritten notes, and voice recordings. All information is carefully screened to ensure it contains no identifying details.
People typically choose anonymous sperm donors for three main reasons:
In some cases, cultural norms and local legal restrictions may also contribute to a preference for anonymous sperm donation.
While there is some truth to all these motivations, there can be exceptions. For instance, choosing an anonymous donor may simplify things for parents, but it might make them more complicated for donor-conceived individuals. Likewise, these motivations are not exclusive to anonymous donations. Many ID Release options establish clear boundaries and have strict rules about what is and isn’t permitted.
That’s not to say ID Release is better than No-ID Release or vice versa. The choice is a personal one and dependent on your preferences. However, it is important to recognise that decisions surrounding sperm donation and donor selection can be complex and multifaceted.

An open identity sperm donor (ID Release) is a donor who agrees to the release of identifying personal information to any individuals conceived using their sperm, once that individual reaches a certain age. The legal threshold for ID Release is often 18. However, some countries release information when a donor-conceived individual reaches the age of 16.
While non-anonymous sperm donors’ ID information will be released, there is no guarantee of contact between donor and the donor-conceived individual. Typically, the donor-conceived individual has to initiate the process by requesting contact, and then the ID donor can agree or decline. The donor is not allowed to initiate contact. It’s also important to note that parents do not usually receive any identifying information about the donor before or during fertility treatment.
A donor-conceived adult who was conceived using sperm from an ID Release donor can access personal information that often includes the donor’s:
The information released varies from country to country, as do the precise rules surrounding identity disclosure, so it’s always important to research local regulations.
The formal process for requesting donor details is also region-specific. In most countries, it involves contacting the relevant local authority responsible for the national register (such as the HFEA in the UK or SaReg in Germany) and requires evidence of donor conception.
In cases where the sperm donor was registered with European Sperm Bank, more information is usually contained within our records than in any national register. Consequently, we also facilitate ID Release. Our three-step process involves:
As the first step of the process, we require documents confirming the individual’s donor conception. We need the following details and documents:
Once the individual’s kinship with the donor is confirmed, our coordinator schedules a session to talk through the next steps. During this conversation, the donor-conceived individual and the coordinator also discuss how they feel about learning the identity of their donor, and how to deal with those feelings.
Before we give out a donor’s identity information, the individual must sign a donor confidentiality agreement. The purpose of the agreement is to protect the donor’s privacy and to clarify that the individual understands what they can do with the information they receive.
We inform the donor once the individual receives the donor’s ID information. At this point, there is contact possibility and, if the donor-conceived individual wishes to request contact, we do so on their behalf. The donor then agrees to or declines the request.
Donors have no right to any information about children conceived using their sperm or the parents of those children.
Open identity sperm donors and aspiring parents choose ID Release because they believe it:
Increasingly, it’s also a legal requirement. In some countries, such as the UK, all new sperm donors must agree to ID Release and be an open donor in order to donate.

The difference between anonymous and non-anonymous sperm donors is whether identifying information is available for a donor-conceived individual when they come of age. The ID Release vs No-ID Release question is difficult, and both donors and aspiring parents often have to think carefully about their decision.
Donor anonymity laws determine whether anonymous, open, or both donor types are available, and this varies from country to country.
As you can see, the legality of particular donor arrangements varies significantly and is entirely dependent on each country’s restrictions.
Donor identification laws in some countries no longer permit anonymous donation because they believe transparency protects the rights of donor-conceived adults who want to understand their history and origins. At the same time, sperm donor anonymity has become harder and harder to protect in the age of readily available genetic testing and genealogical tracing websites.

Children respond differently to donor anonymity, and research shows there is a wide range of experiences and feelings towards anonymous donation.
Some donor-conceived children show no interest in learning the identity of their donor, and it plays no role in their lives and doesn’t affect their sense of belonging to a family.
For others, learning who their donor is an important part of their personal narrative and a necessary step in understanding who they are and where they come from.
Whether their donor is ID Release or No-ID Release, experts recommend parents talk to donor-conceived children about their origins as early as possible, in an age-appropriate way. Donor conception conversations should prioritise:
Support (if you need or want it) – asking for help from a professional is a positive step if you’re feeling apprehensive about these conversations. While many parents don’t feel they need this support, many others find it extremely valuable.
Sperm donor anonymity depends on the country, with some countries only permitting ID Release, others mandating anonymous sperm donation, and several allowing both. Where anonymous sperm donors are still able to donate, sperm banks implement strict measures to secure their anonymity.
Meanwhile, as DNA testing has become more accessible, anonymity is less absolute. For instance, it may be possible to identify an anonymous donor if a donor-conceived individual performs a DNA test and one of the donor’s relatives is registered with a genealogy website.
Regulations typically prevent donor-conceived children from contacting anonymous donors later in life. However, you cannot anticipate the impact of anonymous sperm donation on a child, and some donor-conceived individuals may still try to find and contact their donor. Accessible DNA testing has made this considerably easier.
No, anonymous sperm donors cannot contact donor-conceived children or their parents. Neither ID Release nor No-ID Release donors receive any information about the individuals they donate to or the children conceived using their sperm. They cannot initiate contact.
