Open ID Donor, Blood Type and Ancestry

Do you have open ID donors?

Yes, we have open ID donors. We call them "Non-Anonymous" donors.

They can also be called "ID disclosure" donors as well as "known" donors.

The Non-Anonymous donors have contractually accepted that the children, when they have turned 18, can gain access to their identity. You can search for Non-Anonymous donors in Donor Search.

Where are your donors from?

The majority of our donors are Danish and reflect the general population in Scandinavia. Scandinavia is a historical and geographical region centered on the Scandinavian Peninsula in Northern Europe and includes the three kingdoms of Denmark, Norway and Sweden.

However, as a part of Cryos International we have donors with other ethnical backgrounds and phenotypes.

What type of donor should I choose?

In some countries, it is illegal to use Non-Anonymous donors and in others it is illegal to use Anonymous donors, so remember to check your country's regulations.

  • If a lot of information about the donor is important to you, you should choose a Non-Anonymous donor with an Extended profile. However, before choosing, please ensure that the healthcare professional accepts treatment with Extended profile donors as some only treat with Basic profile donors

  • If you want to know as little as possible about the donor, you should choose an Anonymous donor with Basic profile

Example in the UK:
If you are going for treatment by a healthcare professional in the UK the donor has to be Non-Anonymous and you should select the UK Standard in our donor search to see all the available UK compliant donors.

Is blood type important for my choice of donor?

The donor's blood type is tested according to the AB0-system (A, B, AB or 0), and the Rhesus-system (-/+). It is rare that the blood type has an effect on the choice of donor, just as rare as it has a role when finding a partner under natural conditions. If you choose a donor on the basis of blood type, please remember this could reduce the selection of donors drastically.

The blood type is important in two cases:

  1. If the woman’s blood type is Rhesus negative (expressed Rh-) and if the donor is Rh+.
    In this case there is a 50% risk that the child will get the blood type Rh+ and the possibility that the mother creates antibodies against the child is present. This is normally not a problem in the first pregnancy, but during the following pregnancies the child's condition must be followed carefully.

  2. If you do not want to tell the child that it is a donor child. 
    If the social father's blood type is different than the possible combinations according to the donor’s blood type, it will be clear, that the social father cannot be the genetic father. If you are planning to tell the child about their origin, this has no relevance.

What are alias donors?

From 2001-2006, Cryos International – Denmark ApS released donor sperm from certain donors in the USA.

The fictitious name was used for marketing purposes in the USA, while the original number was used in Denmark. However, since 1st of March 2009, all the alias donors have been presented together under their fictitious name, and the documentation now clearly indicates (Summary of Records) when the donor is an alias. Since 1st of March 2009, Cryos has not sold alias donors under numbers, only under fictitious names.

See example of an alias donor.
