There are a number of important choices to make when you choose your sperm donor. First, you need to consider if you would like an Anonymous or a Non-anonymous Donor. This decision is dependent on the restrictions in your country as well as your individual preferences. You can read about Anonymous and Non-anonymous Donors here.
You must also consider how much information you would like to have about the donor. You can choose a donor with a Basic Profile, where you get only basic information about the donor, or a donor with an Extended Profile, where you get a lot of personal information about the donor. Read about Basic and Extended Profiles here. Some of the donors also have photos of themselves as adults available.
You can use the Donor Search to find a donor who matches your criteria.
Yes, some of the donors have photos of themselves as adults available, and you can purchase access to see them. Read more about donors with adult photos here.
The majority of our donors are Danish and reflect the general population in Denmark. However, some of our donors are staying in Denmark as exchange students, working abroad etc. Our donors have many different ethnical backgrounds and phenotypes.
All our sperm straws meet the specific requirements in force at the time of the donation regarding screening, quarantine, age and anonymity. Over time, the screening panel has been extended and today it includes 46 of the most common recessive genetic diseases.
The donors’ 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 relevance towards the choice of donor, just as rare as it would be when finding a partner under natural conditions. If you choose a donor based on the blood type, please remember that this could limit the availability of donors when making your selection.
The blood type is important if the woman’s blood type is Rhesus negative (expressed Rh-) and if the donor is Rh+. In this case, there is a 50% chance that the child will get the blood type Rh+ and there is the risk that the mother will develop antibodies against the child. This is normally not a problem in the first pregnancy, but the following pregnancies should be monitored carefully.
Yes, you can use a friend or an acquaintance as a donor in Denmark. You can read about Known Donor here (in Danish).
Countries have different regulations regarding selection, screening and approval procedures for donors and donor sperm. We call these Standards. A donor/sperm straw can be released according to one or several Standards.
At Cryos, we operate with the following Standards: DK, EU, FI, NL, ISR, ITA, NO, NYS, SE, UK, USA.
If you are going to receive treatment in a fertility clinic in one of the above-mentioned countries, you should use the corresponding Standard. If you are going to receive treatment in a clinic in a country that is not mentioned above, please ask your fertility clinic for advice on which Standard to choose.
You can search for a specific Standard in the Donor Search.
Read more about Standards here.
MOT is short for motility which represents the number of active sperm cells per ml sperm. For example, 1 ml MOT20 contains a minimum of 20 million active sperm cells after thawing. Our sperm straws contain 0,5 ml which means that each MOT20 straw contains at least 10 million active sperm cells.

At Cryos, you can buy two types of sperm straws: ICI and IUI.
ICI is unwashed/unprepared sperm. ICI straws can be used for intra-cervical insemination. ICI straws cannot be used for intra-uterine insemination without prior preparation as this may cause a severe allergic reaction. However, you can buy ICI sperm straws for intra-uterine insemination, if your fertility clinic prefers to prepare the sperm prior to the treatment.
IUI is washed/prepared sperm where all ejaculate fluids have been removed. IUI straws can be used for intra-uterine insemination and for intra-cervical insemination.
Both ICI and IUI sperm straws can be used for IVF and ICSI treatment.
Please ask your fertility clinic for advice as to which type of sperm straws to choose.

CMV stands for cytomegalovirus and is a common virus that can infect everyone. In fact, most people have had a CMV infection by the time they turn 50 without being aware of it. They thereafter will have a positive CMV status.
Some of our donors are screened for their CMV status in order to accommodate use in some countries where testing for CMV is required. You can see the donors’ CMV status under each profile in the Donor Search. None of the donors who have been tested for CMV have an active virus at the time of donation. They are always tested for CMV both before and after the donation.
Since the donor can donate over an extended period of time, the donor’s CMV status can change from negative to positive. The samples which he has donated in the period where he has had a positive infection are disposed of and we do not accept new donations until the screening results show that the virus is no longer active.
An infection with CMV is mostly harmless. However, if a fetus is infected with CMV during pregnancy, the fetus could be at risk. Because of the regular screening and the clean-up of sperm for IUI, the risk is considered to be extremely low.
If you are concerned about CMV, we recommend that you are screened for CMV and discuss your results with your doctor.
You can read more about CMV in this blog post.
Ordering and shipping
The price of donor sperm depends on several parameters. These are for example: the quality of the sperm, Standard, whether you choose an Anonymous or a Non-anonymous Donor, and whether you choose a donor with a Basic or an Extended Profile.
Donor sperm is shipped to destinations all around the world. Shipments are sent in a dry ice container or in a nitrogen tank.
A small dry ice container lasts for 3 days, a large dry ice container lasts for 5 days, a small nitrogen tank lasts for 7 days, and a large nitrogen tank lasts for 12 days. You should count the day of shipping as day one for durability of the sperm straws.
You need to choose the type of container according to the date of your fertility treatment or your ovulation – depending on the treatment method you have chosen. You should also remember to calculate the time from shipment to delivery.
You should place your order at least 2 weekdays before your desired shipping date and up to 4 weeks before your desired shipping date.
You can read more about when to place your order on the page Shipping and delivery.
Delivery takes 1-2 weekdays for most destinations within Europe and 2-5 weekdays for most destinations outside of Europe. However, this may vary depending on destination and other conditions. Cryos cannot guarantee the exact delivery date.
You need to plan your shipment date according to the date of your fertility treatment or your ovulation – depending on the treatment method you have chosen.
Read more about shipping and delivery.
Donor sperm must be stored at a very low temperature (-196 °C) and therefore, you cannot store sperm straws in your own freezer.
You should place an order if your desired shipping date is within the next 4 weeks. However, if you want to reserve the straws from your favourite donor with us for future treatments, you should place a reservation instead.
To place a reservation, you must pay a storage fee. Read more about making a reservation here.
Due to changes in the Danish legislation, Cryos International Denmark, being a Danish sperm bank, can no longer distribute donor sperm to private addresses. Distribution of donor sperm is only allowed to approved tissue centres, fertility clinics, hospital departments and authorized healthcare professionals.
Please contact our Customer Service to learn about your options.
A Quota Reservation is required in some countries to ensure that the limit of pregnancies achieved by the same donor is not reached.
The Quota Reservation guarantees that you can use the donor during your entire treatment and for siblings – even if local quotas have been reached since your first purchase. Please remember to reserve straws for siblings.
To check if a Quota Reservation is required in your treatment country, please see Donor Search.
If you have bought a Quota Reservation but have not obtained a pregnancy and do not wish to continue treatment with the same donor, you can get a refund of the Quota Reservation. To get a refund, please log in to your profile from a computer (not a mobile device) and click on Pregnancies.
If you have become pregnant with the help of a Cryos donor, it is important that you report the pregnancy to us.
We suggest reporting your pregnancy when you have passed the first trimester and before the birth of your child.
To report your pregnancy, please log in to your account on our website and go to the page Pregnancies. Here you can register your pregnancy.
If you have had treatment in a clinic, you should report your pregnancy to both your clinic and to Cryos.
Each country has a pregnancy quota, meaning a limit for the number of pregnancies by one donor. It is important to report your pregnancy to Cryos to ensure that the limit of pregnancies by a donor is not exceeded.
The pregnancy rate is dependent on a lot of different factors. Therefore, we cannot tell you what the expected pregnancy rate is for your treatment with donor sperm.
The pregnancy rate for example depends on the fertility clinic, the treatment method and personal factors such as age and life style.
All donors have been selected and screened according to Cryos' extensive quality assurance, operational procedures and policies for donor recruitment, assessment and screening. Despite this thorough selection and screening procedure, the risk of having a child with a medical condition cannot be eliminated.
Not all conditions are hereditary. However, it is a fact of nature that every human being carries a number of DNA mutations which can be associated with various disorders or conditions. If the condition reported in relation to a specific donor turns out to be hereditary, this information could potentially have significant impact on anyone genetically related to the donor and their family members. Cryos takes reports of conditions very seriously and we will not withhold information from any individual related to the donor.
When Cryos receives a report of a condition, the donor is immediately removed from our Donor Search and put on hold during analysis and investigation.
Read more about how we handle conditions here.
Donors who have been registered with a genetic condition, can only be used if you have already conceived a child with the donor and wish for a sibling with that same donor.
If you want to buy sperm from a donor with a registered condition, you must therefore declare that you already have a child with this donor, and that you have received and understood the information concerning the registered condition. We do recommend you to seek local genetic counselling if you have questions about using a donor with a registered condition for a sibling.
Cryos follows the national quota which defines the number of families that can use a donor in a given country. You can always check if the national quota has been reached for a specific donor by selecting your country of residence and country of treatment in the Donor Search.
Please, check with the authorities in your own country, if you are interested in knowing the national quota.
You do not need to worry about the partnering of two donor conceived children from the same donor. The risk that this will happen is extremely low, and the risk may only increase by a few percent compared to normal procreation.
Cryos follows the national quota which defines the number of families that can use a donor in a given country. This helps to ensure that the risk of inbreeding remains extremely low.
You can always check if the national quota has been reached for a specific donor by selecting your country of residence and country of treatment in the Donor Search.
If you have chosen a Non-anonymous Donor, your child will have the possibility of getting in contact with the donor in the future. If you have chosen an Anonymous Donor, Cryos will never reveal the identity of the donor.
When you have registered a pregnancy, you will be able to download a Donor Child Certificate. You will find the certificate by logging in to your account. You can add the name and date of birth of your child to the certificate.
If the donor is Non-anonymous, the child can contact Cryos once he or she turns 18 and present the Donor Child Certificate to get the donor’s contact information. Unfortunately, Cryos cannot guarantee that the donor will want to establish contact in the future.
If you have further questions, please contact Customer Service.
Each country has their own regulations concerning donor sperm. This is for example with regards to donor anonymity, and the people who are allowed be treated at a clinic (heterosexual couples, homosexual couples and/or singles).
In most cases, you will be able to find the current regulations on the health authority of your country’s website.
At Cryos, we comply with regulations worldwide by using country specific Standards. If you find your country on the Standards list, you can be assured that we are compliant with your country’s regulations.
However, we also recommend that you talk to your fertility clinic about the specific regulations in your country of treatment. They will be able to guide you in choosing the right type of donor sperm for your treatment.
