Donor sperm

Our donor sperm categorisation: These are your options at the StorkKlinik

Anonymous donor sperm: basic information (eye colour, hair colour, height, weight)

Anonymous plus donor sperm: basis basic information + blood type and occupation/education

Open donor sperm: the same as anonymous plus and with the option to learn the donor’s identity (you should check this yourself with the sperm banks)

The sperm banks are all different, and there may be differences in what they define as identity and whether it will be possible to contact the donor later in the child’s life.

Which donor should I/we choose?

Know which options are available and decide what is right for you, and not least a future child. See these five important questions from Midwife Julia Buus Nicholson at StorkKlinik in relation to donor selection and having a donor-conceived child.

Five important questions about donor selection and having a donor-conceived child

1. Would you like an open, anonymous plus or an anonymous donor?

It is entirely up to you. No decision is better than another one, even if there appears to be an increasing number of women—particularly in Denmark—who are opting for open donors. Our advice is that in the majority of cases whatever feels right for you and your partner will be best for your child. The important thing therefore is to consider the options available to you and decide on that basis.

When we ask single women and lesbian couples about their decision, we can see that most of them choose open donors, particularly in Denmark, where there is a lot of openness about different types of families. It is also to do with the fact that women do not want to restrict the child. Some single women might say: “As I can’t give my child a father, at least I can use an open donor.” We’re also finding that more heterosexual couples are choosing open donors than before due to an increased openness generally in society. 

Others choose an anonymous plus or an anonymous donor, because they want to take responsibility for the child (choose on the child’s behalf) and thus not just pass on/hand over a possible decision to the child regarding finding out more later in life. 

Nowadays, there is also another essential issue that has significance regarding the choice of a donor. Because what does choosing an open donor mean? An open donor is a broad term. The law does not state that the child is entitled to meet the donor on turning 18, but that the child is entitled to know the donor’s identity. This raises another question: What does identity cover? Is it a name, an address or just information about him? We don’t know as the sperm banks offer something different.

We have had open donation since 2007 in Denmark. That means that the oldest donor-conceived child has not yet reached 18. Therefore, we don’t know how the sperm banks will handle this issue. For some people, it is therefore more attractive to select an anonymous plus or an anonymous donor, simply because it is much easier to explain this to the child. The answer is not: “We’ll have to see what you can find out when you are 18”. If an anonymous plus or an anonymous donor is chosen, then we currently know exactly what information the child will get. 

In some cultures (particularly abroad), having a donor-conceived child is frowned on. For that reason, we meet some women and couples who select an anonymous donor because they do not want to give either the child or anyone else details about how the child was conceived.

2. What will you decide yourself, and what will you leave up to the clinic?

One important thing you should consider is: What will you decide yourself? For some people it is really important to be involved in every decision. Some people want a donor with blond hair and blue eyes. Other people are more concerned about having a donor that shares their values, outlook on life and interests. While some people don’t want to have any influence on this decision. 

However, most people have one or more things on their wish list, and there is certainly nothing wrong with that. It is important to emphasise though that we cannot give any guarantees. Even if the donor has blue eyes, the clinic will never be able to guarantee that the child will also have blue eyes, etc. 

If the only thing you want is a child with blond hair and blue eyes, then the clinic can select a donor with these features for you. If we are selecting a donor for you, we will not have any more information that you. We do not know the donor; it is the only the sperm banks who deal with donors.

3. What will you do if it transpires that the donor has a hereditary disorder?

We all have genetic abnormalities. This also applies to a donor. Even though the donor will have been screened and tested for several different disorders, naturally we cannot give any guarantees. But generally, the child is better off than most naturally-conceived children, because the donor is screened and tested. In many cases, the donor will typically have previously donated sperm for other children, and we would be informed if, for example, he was in quarantine while investigations were taking place to see if the reported malformation or disorder in a child could be attributed to the donor. 

4. Are you keen to have more than one child?

We’re often asked: “How much donor sperm should I buy?” It is really difficult to advise you about as we can’t know this. However, an important question to consider early in the process is the possibility of having full siblings: “If everything goes well, will you have more than one child? If so, is it important for you to have the same donor?” This, naturally, will have a bearing on the amount you should buy/reserve at the present time, and applies to open, anonymous plus and anonymous donors. 

5. When will you tell your child that they were conceived via a donor? 

What have you actually thought about saying to the child? When will you tell your child? How will you tell your child? When choosing to have a donor-conceived child, we recommend that you think about the child’s story right from the start.

We find that some people take things as they come, other plan what they’re going to say while others like to write a diary from when they first start to consider the process up until they’re holding a baby in their arms. The diary can later become a gift for the child. 

The advantage for lesbian and single women is that the child will certainly ask when they are ready to get an answer. A two-year-old might say: “Where’s my father?” Here it’s just a matter of being ready. When the child is five years old, he/she may ask again. We have met others who tell the children everything from when they’re infants.

And don’t forget … a donor-conceived child is a much longed-for child. They were longed-for way before they were conceived. It’s an option. Their mother has wanted them, as has their co-mother or father. And they were wanted by the donor. It’s a big gift, including being told this later in life!

Three tips if you want to use donor sperm

Midwife Julia Buus Nicholson gives her three top tips for if you want to use donor sperm.

1. Listen to your gut

When you decide on a donor, it should feel right. There is no right or wrong decision here. But if it feels right to you, then it is the right decision. 

2. Openness and honesty are the most important things

The most important thing is that you are honest with your child and that you tell the truth. Tell the truth right from the start, not when they reach the age of 15. All the research shows that it is much easier for the child to handle the truth than to feel that there is a taboo associated with being a donor-conceived child. Single and lesbian women can’t avoid the subject, but for heterosexual couples this is something that should be addressed. 

It’s one thing being honest with your child, but what you tell everyone else is another matter. What does a single woman living, for example, in a small village in Northern Norway with her two-year boy say? Does she change her story depending on what she thinks will be best received: “I was in a relationship with this guy, but it didn’t work out” Or does she say: “I went to Denmark and got donor sperm?” 

If she tells her child and everyone else the truth thereby showing that she is happy with her decision, then the child will feel OK and will realise that there is nothing wrong with being a donor-conceived child.

3. Think about you child 

Also put the child’s needs before your own. Think about how you imagine your child will react as he/she grows up.  

The sperm banks

The sperm banks offer a selection of different donor types/donor sperm with different options regarding information about the donor. 

It is the sperm bank that receives, checks and distributes semen samples to the fertility clinics. 

The donors are men with a Caucasian/European appearance and their average age is 25. If required, we can request donor sperm with another ethnic origin

Most sperm donors are university students in Denmark, and their motivation is typically both idealistic and financial. 

To be approved as a sperm donor, the donors undergo several medical checks and they must be healthy and not have any illness in their family. 

The Danish Health Authority website has all the details about the medical checks donors must have before a small number (8–10%) of them are approved and can be used as donors. 

Before the donor sperm is released for sale, it will have been in quarantine, while the donors provide negative tests for infectious diseases three and six months after providing the actual donation.

This is a requirement that the Danish Health Authority imposes on the sperm banks to reduce the risk of infectious disease including HIV.

We work with the following sperm banks:

If you are having fertility treatment using donor sperm, there are several options available to you: 

  • You can let StorkKlinik choose a donor for you based on your wishes regarding eye colour, hair colour and height. We will do our utmost to accommodate your wishes, but we cannot guarantee anything.
  • You can purchase donor sperm through StorkKlinik based on your wishes regarding eye colour, hair colour and height. You will be guaranteed your wishes, and the sperm will be ready when you come for insemination. Phone us at +45 3257 3316, and we would be happy to assist you with the practicalities.
  • You can purchase donor sperm yourself and choose from different characteristics. The following are links to the sperm banks we work with: 
  1. www.europeanspermbank.com
  2. www.cryosinternational.com
  3. www.sellmerdiers.com 

If you are registered here in the clinic, you have free login to the European Sperm Bank’s list of donors as well as a discount code for Cryos International. This allows you to select a donor yourself and order donor sperm.

If you phone or email us, we will email you the information that should be used.


If you would like to order specific donor sperm, you can do this yourself via one of the sperm banks or you can let StorkKlinik do it for you.

This should be done after you consultation and before you start treatment. The donor sperm will then be reserved in your name. You pay for the number of portions of donor sperm that you would like to have sent to StorkKlinik, a freight charge and an annual administration/depot fee to store 1–10 portions in the depot. 

At StorkKlinik, it is also possible to reserve donor sperm from the same donor with whose sperm you became pregnant. Then the same donor can be used for siblings. This depends of course on whether there is remaining sperm from the donor in question in the sperm bank. 

If you have had a child using donor sperm at another clinic, StorkKlinik can investigate if it is possible to request donor sperm from the same donor. 

For this however, you must have been given the donor number from that clinic.

Known donor

Do you have a known sperm donor?

If you would like to use your own or a known donor (who is not a partner) for treatment in StorkKlinik, the known donor will be subject to the Danish Health Authority’s practice and legal requirements regarding screening through interview, physical examination and blood tests as well as swabs for certain infectious diseases.

1. Screening through interview for sperm donation from a known donor.  

All known donors should be assessed by a medical professional at StorkKlinik. The assessment is based on the risk of infectious diseases and the risk of passing on any hereditary disorder. The donor must complete and sign a declaration in which he makes a solemn declaration about his health. He also consents to having his health information disclosed to the woman/couple to whom he wishes to donate. There will also be a physical examination in connection with the consultation.

2. Freezing sperm

Freezing sperm as well as relevant and mandatory tests are done in the European Sperm Bank 

3. A written evaluation as well as verbal information about any risks and results are provided

You must sign an informed consent form, and then your fertility treatment can start. 

If you are thinking of coming here with a known donor, please phone (+45 3257 3316) or email us (» info@storkklinik.dkus) first, so that we can give you the best possible information.
