The most suitable shipping method for you depends on how precisely you can predict your ovulation date, how long you need to store the sperm before use, and on which day of the week the shipping takes place. 
If it is difficult to predict your ovulation date we recommend that you choose a nitrogen tank. If the sperm is delivered to a clinic that has a nitrogen tank then it is also possible to choose a dry ice shipment.

We do not recommend dry ice shipments on Thursdays and Fridays due to the risk of delays over the weekend.

 

For shipments to Europe (outside Denmark)

 

If you choose "pick up" your package can be ready for pick up from 8:30am on the requested pick up date. If you have someone else pick up your order for you, you should fill out this Power of Attorney (POA) with information about the person picking up the package on your behalf. The POA should be presented to Cryos prior to the time of pick up.

Please place your order well in advance. Cryos needs 2 days to handle your order before it is shipped. Then you need to add the shipping time, which is 1-2 work days for most destinations in Europe and 2-5 days for other destinations.

With payment of an additional late order fee orders can be dispatched on the same day the order is received.

Home insemination:
ICI and IUI-ready straws can be used.

We recommend using 2 x 0.5 ml straws MOT20, i.e. with a minimum of 20 million sperm cells per ml, alternative for instance 1 x MOT30 + 1 x MOT10. If 0.4 ml straws you will need 3 straws. Straws with MOT10 or higher MOT can also be used.

Straws with MOT5 should not be used.

If the timing is correct, there is no need for more than one insemination per cycle. We recommend using a urine ovulation test-kit, supplied from any pharmacy. Follow the instructions attached.

IUI treatment at a clinic:
ICI and IUI-ready straws can be used.

IUI-ready straws:
We recommend using 1 x 0.5/0.4 ml straw IUI MOT10 per treatment.

Straws with a lower or a higher motility than MOT10 can be used.

We recommend that you ask your clinic for advice before you make your order.

ICI-straws:
ICI straws can be used. The sperm must be processed at your clinic prior to treatment.

We recommend using 1 x ICI MOT20 or 2 x ICI MOT10 straws or higher motility per treatment.
We recommend that you ask your clinic for advice before you make your order.

We do not recommend using the swim-up method for donor sperm that has been frozen. If ICI donor sperm is to be processed using the swim-up method, you should use 2 x ICI MOT20 straws or higher quality per treatment.

IVF and ICSI at a clinic:
ICI and IUI-ready Straws can be used.

We recommend using 1 x 0.5/0,4 ml straw MOT5.
Straws with higher motility than MOT5 can be used.
We recommend that you ask your clinic for advice before you make your order.

CMV stands for Cytomegalovirus. It is a very common virus, which most people have had before turning 50 years old. Approximately 50% of people aged 20 have been temporarily infected with this virus.

We only screen some of our donors for CMV to accommodate use in certain countries. It is only allowed to use sperm from a donation period where the donor was IgM negative (did not have an active infection). In these countries, sperm from a donor who has previously had the infection and is now IgG positive may only be used for women who themselves are IgG positive (who have had the infection earlier).

An infection with CMV is mostly harmless. However, if a foetus is infected with CMV during pregnancy, the foetus could be at risk. This can happen if the mother has a primary infection of CMV during pregnancy.  Because of the regular screening for IgM antibodies and the clean-up of the sperm for IUI (centrifuging), the risk of virus in the sperm is considered to be minuscule.

The donors who have no CMV status on the website have not and will not be screened for this.

For all donors tested the status will show on the website.

Read more about screening.

The donors undergo rigorous selection criteria and thorough medical examinations prior to acceptance and clearance to become a donor. Donors are screened for a series of infectious and hereditary diseases. Furthermore, donors pass a number of physical and psychological tests and despite being healthy young men, only the best pass to become a Cryos donor.

Read more about screening.

Yes, we deliver to private customers.

There are many issues which must be considered, e.g. medical examination, diagnosis, scanning, timing, and hormonal stimulation or other types of medication. We recommend that you are always under the care of a physician or other health professional.

If you are treated by a doctor or other healthcare professionals your chances of getting pregnant is three to four times higher per cycle than by home insemination, as a doctor or healthcare professional can offer you IUI or IVF treatment.

If you do not want, or do not have access to treatment by a doctor or healthcare professional you can read more about home insemination here.

Yes, we do.

However, please check your country’s regulations regarding treatment with donor sperm. Some countries only allow treatment with Anonymous donor sperm and some only with Non-anonymous donor sperm.

For delivery to certain countries a deposit for the tank might be required.

This means that you need to make sure that the donor you select meets the standard for your country. Read more about Standards her.

 

Please place your order at least two weekdays before the shipping date as we need 2 days to process your order. Then you need to add the shipping time, which is 1-2 work days for most destinations in Europe and 2-5 days for other destinations.

With payment of an additional late order fee orders can be dispatched on the same day the order is received. Cryos disclaims all responsibility in case of delay.

The shipment will include the following documentation:

  • Packing List
  • Summary document, 'Donor Characteristic & Quarantine Release' form, with the donor’s characteristics and Standard release – download example
  • Safety warning for handling of dry ice (CO2) and liquid nitrogen (LN2)
  • Instructions manual (for private deliveries)
  • Inseminations-kit for home inseminations (for private deliveries)
  • Instructions for returning of the nitrogen tank (only for LN2 deliveries)
  • Shipping label for returning of the nitrogen tank (only for LN2 deliveries)

Yes, you can.

When you have found your favorite sperm donor you should make a reservation immediately. There is always a risk that the donor you are using will be sold out. Almost daily we hear from customers who are disappointed, because their donor has disappeared from the donor list.

Read more about Reservations.

On average it takes 5-6 IUI treatment cycles to get pregnant. Clinics report an average pregnancy rate between 10-40% per treatment cycle. It does however differ from clinic to clinic and from person to person depending on the patient's fertility, health, and age as well as the hormone stimulation, timing of the treatment, sperm preparation method, the quality of the sperm, insemination method, the clinic's experience, etc. The pregnancy rate is higher in the beginning of the treatment because the most fertile get pregnant first and decreases with more treatments. In a random group of patients a total of 50-60% will get pregnant after 6 IUI attempts and about 80% after 12 attempts.

Read more about how many straws you need per treatment.

If the sperm donor with whom you have previously registered a pregnancy is sold out, you can be registered on a waiting list – for siblings only. We will contact you if sperm is released from quarantine at some future date or if others who have made a reservation cancel their reservation.

We accept Visa, Visa Electron, MasterCard, and Dankort.

In the transport box you will find an envelope with a preprinted return label and a leaflet with instructions on how to return the tank. Other information required by the courier, such as weight, is shown on the return label as well. The return charges are included in the shipping price.
We kindly ask you to use one of the above-mentioned procedures. Choosing an alternative shipping option may result in loss of the tank and a potential claim of EUR 1000.

If you have any questions regarding returning the tank correctly, please contact our Customer Service for guidance.

Should I pay extra for returning the tank?

No – if you use the return label enclosed in the transport box, the return charges are included in the shipping price.

Can I hand in the tank at the postal office?

No – we kindly ask you to schedule a pick-up of the tank from our website www.cryosreturn.com, directly on the courier’s website or by phoning the courier. Choosing an alternative shipping option may result in loss of the tank and a potential claim of EUR 1000.​

Intra Uterine Insemination (IUI) is an insemination where the sperm in inseminated directly into the uterine cavity. This is done at a clinic. Scientific studies have shown a three to four times higher pregnancy rate through IUI than through vaginal/cervical insemination (ICI).

However, before IUI can be carried out, the sperm must be prepared through swim-up or density gradient centrifugation in order to remove prostaglandins (from the prostate) and bacteria from the sperm. ICI straws must always be prepared. If this is not done, the patient may react negatively or get severe cramps.

Cryos offers IUI ready sperm that has been prepared and is ready to use for IUI treatment.

Intra Cervical Insemination (ICI) is a vaginal insemination, where the sperm is inseminated into the entrance of the cervical channel.

ICI is performed with raw (unwashed) sperm with its content of seminal plasma, prostate secretion, etc. Raw sperm is not sterile and because of the contents of prostaglandin it must not be used for an intra uterine insemination (IUI).

The pregnancy rate for ICI varies from 20-25% for young, healthy women’s first treatment to less than 5% for older women. If no pregnancy is achieved after 3-6 treatment cycles we recommend more advanced treatment such as IUI or IVF (In Vitro Fertilisation).

If ICI unwashed sperm is not available of your favorite donor then IUI ready sperm can be used instead.

The instructions manual for home insemination is included in all shipments of donor sperm to private customers. You can also download it.

 

We have two types of sperm donors: Anonymous and Non-anonymous. Both groups include Basic and Extended profiles. You can also choose an Exclusive donor from both groups.

Donortypes:

  • Anonymous + Basic profile
  • Non-anonymous+ Basic profile
  • Anonymous + Extended profile
  • Non-anonymous + Extended profile

Anonymous

The identity of Anonymous sperm donors always remains confidential.

Non-anonymous

Children can learn the identity of Non-anonymous sperm donors at the age of 18 if they can document or render probable that they are the result of a conception with donor sperm from a specific Non-anonymous sperm donor. Documentation requirements are not particularly stringent. Sperm donors have agreed to be contacted by the donor children.

For more information, please read our Terms of Agreement.

Basic profile

Sperm donors with a Basic profile, anonymous as well as non-anonymous, are registered under a number like 456, 8756 or 11250. Basic profiles only provide information on race, ethnicity, eye colour, hair colour, height, weight, blood type and usually profession/education.

Extended profile

Sperm donors with an Extended profile, anonymous as well as non-anonymous, are registered under a fictitious name such as PER, OLUF or SVEND. The Extended profiles consist of up to 5-6 pages of personal information on the sperm donor's background, education, family background, interests and hobbies. The following additional information may apply: staff impression, childhood photos of the sperm donor, a handwritten greeting, a sound recording of the sperm donor's voice and EQ profile.

Read more about the sperm donors.

 

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 clinic accepts treatment with Extended profile donors as some clinics 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.

If the regulations of your country says that you cannot use a certain type of donor profile for clinic treatment, remember that you can order any type of donor for home insemination. You choose, what is best for you.

Example UK:

If you are going for treatment at a clinic in the UK the donor has to be Non-anonymous and you should select the standard UK in our donor search engine to see all the available UK compliant donors.

If you want to do home insemination you can choose among all of our donors.

Yes, we have open ID donors.

They can also be called "ID disclosure" donors and some "known" donors. We call them "Non-anonymous" 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.

Sometimes donor children, parents or donors contact us in order to get in touch with each other. It may sound positive, but we have obligations towards the donors as well as to the future parents.

Clients and donors have signed an agreement never to try and contact the other part. But of course we have no agreement with the children and cannot influence their behavior.

The identity of the Anonymous donors will be confidential forever.

The identity of the Non-anonymous donors, is kept secret until the child turns 18. If the child at this point wants to get in contact with the donor, we can provide the child with the donor’s name, personal health security number (or other ID number) and last known address. The donors have given a consent to meet the children, however Cryos has no responsibility for this. The children need the Donor number/name in order to request the information.

If you want to ensure that your child can contact the donor, you must choose a Non-anonymous donor.

 

Exclusive donors are presented with a black star in Donor Search.

An exclusive donor means that no one has purchased sperm from them yet. All our donor types can be purchased as an exclusive donor as long as nobody else has purchased/reserved sperm from the donor in question.

To get an exclusive donor you have to buy the donor out. 

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 (Donor Characteristic & Quarantine Release) 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.
See complete list of alias donors.

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 affect on the choice of a 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:

  • 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 at problem in the first pregnancy, but during the following pregnancies the child's condition must be followed carefully.
  • 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 its creation, this has no relevance.

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.

The donors undergo rigorous selection criteria and thorough medical examinations prior to acceptance and clearance to become a donor. Donors are screened for a series of infectious and hereditary diseases. Furthermore, donors pass a number of physical and psychological tests and despite being healthy young men, only the best pass to become a Cryos donor.

Read more about screening.

In order to protect the privacy and rights of our donors and recipients we cannot answer the specific question of how many children our donors have. 

Instead, we can inform that it is Cryos International's policy to follow any national limitation or national quotas*. 

Pregnancy quotas are made in order to limit the risk of inbreeding. However, due to strict regulation in many countries low supply of donor sperm is a consequence, which has lead many patients to cross boarders ("fertility tourism") in order to receive treatment.

You can always check if a donor has reached the national quota under Donor Search when you click on a donor - Donor Details (Check pregnancy quota).

*) The "national quota" is the maximum number of pregnancies permitted per donor based on any kind of regulation in the form of laws, circular letters, or collective agreements from organizations in the country in question (if such limitations are known to Cryos). Abortions are not included.

Our decision to make information about donors with suspected or known genetic conditions available to our customers is based on our desire to be as transparent about these conditions as possible. Genetic conditions, also commonly referred to as hereditary diseases, are present in the general population and thus also in our selection of donors. All individuals carry genes that are potentially hazardous. Some genes are recessive and we may never know that we carry them whereas others will exert their influence through interactions with environmental factors and events in the person's development and lifestyle.

Genetic screening at Cryos is driven by a clinical need and scientific evidence and it is determined on the basis of a pragmatic balance of the donors as well as the recipients interests. Despite this screening procedure, unknown hereditary conditions may be transmitted. When we are informed about this, we will make the information available to our customers.

So, on the one hand it is important to be transparent about donor conditions but on the other hand it is also important for us to ensure that our customers have the right "not to know" and to say stop before being confronted with a donor’s condition.

If you choose to be informed about a donor’s conditions, the information could potentially have tremendous impact on your own life as well as the individuals genetically related to your donor, including any children and any other family members. As soon as you have acquired knowledge about your donor’s condition, you have a responsibility (and possibly an obligation) to inform your family members about the advantages and disadvantages associated with the condition.

So, do you want to KNOW about your donor’s condition or do you prefer NOT TO KNOW? Cryos will leave this up to you.

If you want to learn more about the subject, you can read the literature listed below:

To report a suspected condition simply complete the form Report of Condition or call our Customer Service.

The report will be sent directly to our genetic consultant who will assess the information.

In a fast developing world with new technologies and increased genetic screening, Cryos has decided to become transparent about the fact that our donors have genetic conditions. Genetic conditions, also commonly referred to as hereditary conditions, are present in the general population and thus also in our selection of donors. 

If we receive information about a possible hereditary condition in the donor or a donor child, the information will be assessed if there is a possibility that it is related to the donor, the information is made available on our website. A registered condition does not mean that the donor cannot be used, for more information please see the section: Who can use a CON donor?

There is no reason to be concerned about the partnering of two donor conceived children from the same donor. The risk is extremely low, especially if the sperm bank distributes nationally and internationally, as Cryos does.

However, to get a better understanding of the risks, you should know more about consanguinity. Consanguinity, at it’s simplest, means that the DNA of the two parents is too identical. Recessive disorders in the DNA, which both the parents were only carriers of, can result in being passed on to the offspring and affect them. It is important to understand that we all carry plenty of recessive disorders in the DNA (C.J. Bell 2011) also the donors.

However, the risk may only increase by a few percent, in comparison to normal procreation. The larger problem of consanguinity arises if it continues generation after generation, as everybody sooner or later will be affected. This is seen for instance in very small and isolated communities or in royal families. This is not relevant for donors as it is only a one-generation issue.

To avoid or minimize the affects of consanguinity, small sperm banks servicing only a little community should only allow very few children per donor, but it can be up to 1 donor child for every 32,000 citizens if nationally or internationally distributed, according to the recommendation from the American Society of Reproductive Medicine (page 53). This goes to show that consanguinity is only a question about distribution and in fact, consanguinity by sperm donors is considered to be much less frequent than the general risk in the community (J.L. Serre, 2013).

To ensure geographical distribution, we follow to national and international quotas. You can always check if a donor has reached the national or the international quota under Donor Search when you click on "See details" of a specific donor. You can use the "Check pregnancy quota" function to get the right information.

Danish authorities have instructed us that donors who have been registered with a genetic condition, can only be used if the recipient has already conceived a child with the donor. This counts for all countries including Denmark.

However, these donors would under certain circumstances still be applicable as long as there is transparency with respect to the detected condition.

It is a fact that all individuals, and, hence, also all donors and recipients are carriers of several mutations associated with hereditary diseases including diseases with recessive and multifactorial inheritance. Therefore, it is not possible to eliminate this risk, meaning that it can be misleading to withdraw donors with registered conditions because recipients might believe that the donors, who can be purchased, cannot be associated to hereditary diseases. This is not the case, as we know that all people are carriers of hereditary diseases, we just do not know the type of disease. This leads to the question, if you want to have this knowledge at all?

For donors with registered conditions, it applies that we have gained knowledge of a specific condition and subsequently if possible a risk assessment has been established concerning the specific condition, when using the donor.

For a number of cases where it has been possible to identify the exact mutation in a specific gene causing a recessive disease, it is possible to eliminate the risk of using the donor, by testing the recipient for mutations in the specific disease gene. For other types of inheritance, information on the severity of the specific condition together with the risk assessment provides the recipient with the information to decide whether the recipient still wants to use the given donor.

To conclude, if you want to buy sperm from a donor with a registered condition, you must declare that you already have a child with this donor and you must declare that you have received and understood the information concerning the registered condition.

Furthermore, we recommend that you seek local genetic counselling regarding questions about using a donor with a registered condition.

As countries have different regulations regarding selection, screening, and approval procedures for donors and donor sperm, as well as different requirements for documentation, Cryos operates with different "Standards" for release. A donor/ejaculate can be released according to one or several Standards. 

Donors/ejaculates can be released according to the Standards in Denmark (DK), EU, Finland (FI), Holland (NL), Norway (NO), New York State (NYS), United Kingdom (UK), and United States of America (USA).

For home insemination you can use any Standard.

For treatment by a professional in one of the above countries you should use the relevant Standards. For treatment by a professional in another country than mentioned above please ask the professional for assistance.

It is the customers responsibility to ensure that import and handling is legal in the destination country.

Read more about Standards here.

Home insemination:
ICI and IUI-ready straws can be used.

We recommend using 2 x 0.5 ml straws MOT20, i.e. with a minimum of 20 million sperm cells per ml, alternative for instance 1 x MOT30 + 1 x MOT10. If 0.4 ml straws you will need 3 straws. Straws with MOT10 or higher MOT can also be used.

Straws with MOT5 should not be used.

If the timing is correct, there is no need for more than one insemination per cycle. We recommend using a urine ovulation test-kit, supplied from any pharmacy. Follow the instructions attached.

IUI treatment at a clinic:
ICI and IUI-ready straws can be used.

IUI-ready straws:
We recommend using 1 x 0.5/0.4 ml straw IUI MOT10 per treatment.

Straws with a lower or a higher motility than MOT10 can be used.

We recommend that you ask your clinic for advice before you make your order.

ICI-straws:
ICI straws can be used. The sperm must be processed at your clinic prior to treatment.

We recommend using 1 x ICI MOT20 or 2 x ICI MOT10 straws or higher motility per treatment.
We recommend that you ask your clinic for advice before you make your order.

We do not recommend using the swim-up method for donor sperm that has been frozen. If ICI donor sperm is to be processed using the swim-up method, you should use 2 x ICI MOT20 straws or higher quality per treatment.

IVF and ICSI at a clinic:
ICI and IUI-ready Straws can be used.

We recommend using 1 x 0.5/0,4 ml straw MOT5.
Straws with higher motility than MOT5 can be used.
We recommend that you ask your clinic for advice before you make your order.

MOT is short for motility and means the sperms ability to move. A MOT20 means that there is a minimum of 20 million motile spermatozoa per ml in the sample after thawing according to the WHO-standard.

We operate with the following qualities:

  • Intra Cervical Insemination or unwashed sperm :
    ICI-MOT5, ICI-MOT10, ICI-MOT20, ICI-MOT30, ICI-MOT40 and ICI-MOT50
  • Intra Uterine Insemination or washed/purified sperm :
    IUI-MOT5, IUI-MOT10, IUI-MOT20, IUI-MOT30, IUI-MOT40 and IUI-MOT50

A straw of each ejaculate is analyzed after it has been frozen and thawed. The motility after thawing is the stated quality. This means that "ICI-MOT10" has more than 10 (up to 19) million highly motile spermatozoa per ml after thawing.

We recommend that you only store the sperm at home in the container we deliver to you. The sperm cannot be stored in your freezer; it is not cold enough.

The accumulative pregnancy rate should be about 10-40% after the first treatment, and about 15-60% after the second treatment cycle, etc. with a total of about 50-70% after six treatment cycles and about 60-80% after 12 treatment cycles. But the pregnancy rate differs from clinic to clinic and is influenced by the type of patients (specially age) and treatment methods. A Danish University clinic reported an average pregnancy rate of 22.3% for 1131 cycles (developing from 12.9% in 1990 to 34.6%).

The sperm is delivered in clear 0.4 or 0.5 ml CBS High Security Straws. Each straw is marked with the donor number/fictitious name and ejaculate number, e.g. "7890-12" or "CLIFF-25". 

CBS® (CryoBioSystem) High Security Straws are specifically manufactured for safe cryo storage of biological products in liquid nitrogen. Directly after filling, both ends of the CBS™ High Security straw are sealed. This makes the straw absolutely leak-proof, preventing contamination of the sample and its environment.

Manufactured from biocompatible materials, straws are used in medically assisted procreation techniques and particularly for sperm preservation. The CBS™ High Security Straw is a clear, flexible tube made of ionomeric resin. Length: 133 mm (130 mm after sealing). Sterilized by irradiation.

The straw is 510 (k) FDA-cleared and CE-marked as a medical device for storage of human gametes and embryos.

See also RBM Online - Vol 9. No 2. 2004 134-151. Article 1256. The article has an in depth comparison of vials and CBS straws.

CMV stands for Cytomegalovirus. It is a very common virus, which most people have had before turning 50 years old. Approximately 50% of people aged 20 have been temporarily infected with this virus.

We only screen some of our donors for CMV to accommodate use in certain countries. It is only allowed to use sperm from a donation period where the donor was IgM negative (did not have an active infection). In these countries, sperm from a donor who has previously had the infection and is now IgG positive may only be used for women who themselves are IgG positive (who have had the infection earlier).

An infection with CMV is mostly harmless. However, if a foetus is infected with CMV during pregnancy, the foetus could be at risk. This can happen if the mother has a primary infection of CMV during pregnancy.  Because of the regular screening for IgM antibodies and the clean-up of the sperm for IUI (centrifuging), the risk of virus in the sperm is considered to be minuscule.

The donors who have no CMV status on the website have not and will not be screened for this.

For all donors tested the status will show on the website.

Read more about screening.
