MOT is short for motility and means the sperms ability to move or swim. 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 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

For ICI at a clinic or home insemination
We recommend using at least 2 x 0.5 ml straws with a minimum of 10 million sperm cells per ml. This can be achieved by using 2 x ICI MOT10 but we recommend that you use 2 x ICI MOT20 straws or higher motility per insemination. If the timing is correct, there is no need for more than one insemination per cycle.

IUI straws can be used for vaginal and cervical insemination if ICI straws of your favourite donor are not available. In this case you should use a minimum of 2 x IUI MOT10 straws or higher motility.

For IUI at a clinic
We recommend using 1 x IUI MOT5 or 1 x IUI MOT10 straw per treatment. If these straws are not available IUI MOT20 straws or higher can also be used.

ICI straws can also be used, if the sperm is prepared at your clinic prior to treatment. After preparation, there should be at least 2 million motile sperm cells per ml for IUI treatment.
If you use ICI straws we recommend 4 x ICI MOT5, 2 x ICI MOT10 or 1 x ICI MOT20 straw or higher, per treatment. If ICI donor sperm is to be prepared using the swim-up method, you should use 2 x ICI MOT20 straws or higher quality per treatment. We do not recommend using the swim-up method for donor sperm that has been frozen.

For IVF and ICSI at a clinic
Both ICI and IUI straws can be used. We recommend 1 x IUI MOT5 or 1 x ICI MOT10 straw. Higher qualities can also be used.

The instruction for home insemination is included in all shipments of donor sperm to private customers. 

Yes, we deliver to private customers.

There are many issues which must be considered regarding assisted insemination; e.g. medical examination, diagnosis, scanning, timing, and hormonal stimulation or other types of medication. On the basis of this 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 professional 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 have access to treatment by a doctor or healthcare professional please read more about Home Insemination.

Those clients interested in picking up the specimens at our office or having the sperm shipped directly to their home, are required to have a doctor complete a Release Authorization. This form is the doctor's approval for donor semen to be used for artificial insemination either at their office or the client's home. Specimens cannot be picked up in our office or shipped to a home without a signed Release Authorization from your doctor.

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.

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

Cryos disclaims all responsibility in case of delay.

The shipping method which is most suitable 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 which 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. Be advised that dry ice shipments cannot be shipped to New York State.

Type: Durability:
Dry Ice: 3 days from the shipping date
Nitrogen Tank (Small): 7 days from the shipping date
Nitrogen Tank (Large): 12 days from the shipping date

 

If you choose "pick up", your package will be ready for pick up from 8:30am on the requested pick up date. If you have someone else pick up your order 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.

You select the shipping date when placing your order online. The shipping date you select must be at least 2 days after the date you place your order. If your ovulation is unpredictable or variable we can always modify the shipping date of your order at a later stage if needed.

If you require an express delivery, please Contact Customer Service.

The shipment will include the following documentation:

  • Packing List
  • Handling Instructions and Thawing Procedures
  • Safety Warning for Handling of Dry Ice (CO2) and Liquid Nitrogen (LN2)
  • Summary of Records containing test results and Standard release information.
  • Insemination Kit for Home Insemination (for private deliveries)
  • Return Shipping Instructions and Return Shipping Label

Yes, you can.

When you have found the donor you want and you have decided that you want your child to have siblings, we recommend that you reserve straws for more than one pregnancy. If you reserve straws you do not risk that the donor is sold out when you want another child.

We recommend that you reserve more straws than needed. If you get pregnant before all the straws you have reserved are used you can terminate the reservation and 75% of the price of the straws still in Cryos's possession is refunded when the reservation is released. 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 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.

Reasons to reserve less straws:

  • If you find it easy to become pregnant
  • If you are treated with IVF (in vitro fertilisation)
  • If you are under 35 years of age
  • If you have opted for fewer treatments, e.g. three cycle treatments. Continuing treatments over many years can be expensive and mentally draining

Reasons to reserve more straws:

  • If you find it difficult to become pregnant
  • If you use intra-vaginal insemination or intra-cervical insemination (ICI)
  • If you are more than 35 years of age
  • If you want more treatments than average
  • If you simply want more security. The more straws, the greater the security
  • If you have not decided on a maximum number of treatments

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. You will then have 12 days to contact Cryos to purchase the straws. If we do not hear from you within that period of time, the donor sperm on your waiting list will be released and made available to the next person on the waiting list.

Those clients interested in picking up the specimens at our office or having the sperm shipped directly to their home, are required to have a doctor complete a Release Authorization. This form is the doctor's approval for donor semen to be used for artificial insemination either at their office or the client's home. Specimens cannot be picked up in our office or shipped to a home without a signed Release Authorization from your doctor.

The insemination of spermatozoa directly into the uterine cavity is called IUI and 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. 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.

ICI (Intra Cervical Insemination) is insemination of sperm into the vagina or in the entrance to the cervical channel.

ICI is performed with raw (unwashed) sperm with its content of seminal plasma, prostate secretion, etc. Raw semen is not sterile and because of the contents of prostaglandin it should not be used for direct intra uterine insemination (IUI). If ICI-unwashed sperm is to be used for IUI it should be prepared by swim-up or by density gradient centrifugation before use. Only specialist can perform such a treatment.

The pregnancy rate for ICI varies from 20-25% for young, healthy womens 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 instruction for home insemination is included in all shipments of donor sperm to private customers. 

We have two types of donors: Anonymous and Non-Anonymous donors. In both groups you can find Basic and Extended profiles. In all groups there are Exclusive Donors.

The donors are either Anonymous or Non-anonymous. These definitions do not mean that the donors are not identifiable. As donor sperm carry DNA, there is always a risk that donors, recipients and children can be traced via DNA-analysis and maybe otherwise making the privacy questionable in the future.

Anonymous: If the donor is Anonymous Cryos will never release the identity of the donor, and the client agrees not to try to contact the donor.

Non-Anonymous: Non-Anonymous donors identity can be revealed to a donor child when he/she has reached the age of 18. The donor child must contact Cryos.

Basic profile:
These profiles are registered with a number e.g. 3456. Only a few characteristics (race, ethnicity, eye colour, hair colour, height, weight, blood type and in most cases education/occupation) are available. We do not check education/occupation.

Extended profile:
These profiles are registered with a fictitious name, e.g. CLIFF. Extended Profiles have comprehensive information about the donors e.g. background, favorite pet, and family relations.

On most of the profiles you can see the Staff impression - a short, subjective description of the donor by our staff. In most cases you are able to see a childhood photo of the donor as well as hear a voice message recorded by the donor. In 2011 we started to register Emotional Intelligence (EQ). We check the race, ethnicity, eye colour, hair colour, height, weight, and blood type.

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. Before you choose please make sure 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 UK compliant donors available.

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

Yes, we have open ID donors.

Some also call them "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 the 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 to the donors as well as to the future parents. As long as just one of those involved do not want contact, this applies to all.

Parents and donors have signed an agreement never to try and contact the other part, but we have no agreement with the children and cannot influence their behaviour.

If the donor is Anonymous Cryos will never release the identity of the donor.

If the donor is Non-anonymous, Cryos will disclose the identity of the donor (name, last known address and ID-number) to clinics and authorities in countries where this is mandatory before or in relation to import or treatment. Cryos will disclose the identity of the donor to the child itself at the donor child’s request and only once the child has reached the age of 18. The child must document, or render probable, that he/she is the result of a treatment with donor sperm from a specific Non-anonymous donor from Cryos. The code (name/number) of the donor in question must be informed.

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

The donor has agreed to be contacted by the children, but Cryos has no responsibility whether the donor will actually do so in the future.

 

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. New donors are presented with a star in Donor Search and this means that no one has yet purchased sperm from the donor. 

If you want exclusivity for a specific donor you must purchase/reserve all the sperm in stock. If the donor you wish to purchase is still active you will be registered in our system and you will get the priority right for future releases. In order to keep your exclusivity you must continue purchasing/reserving all the straws/sperm that is released from this donor.

You can always cancel the exclusivity by releasing the stock of reserved sperm. In that case 75% of the amount paid for the sperm is refunded - see Reservation

If you want to make the exclusivity permanent you must buy the donor out. This means that you pay and additional amount of which part of the amount is for the donor himself. After we have received your payment, the donor will stop donating. If you buy out the donor you avoid having to purchase/reserve future releases, especially if no more sperm is required.

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

From 2001-2003, donor sperm was released via Scandinavian Cryobank, LLC Seattle. This company was dissolved in 2003, and from 2004 donor sperm was released from a new US-based company – also called Scandinavian Cryobank, LLC New York, which changed its name to the present Cryos International – New York, LLC in 2007. These donors were given an alias consisting of a four-letter fictitious name. 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 when the donor is an alias. Since 1st of March 2009, Cryos has not sold alias donors under numbers, only under fictitious names.

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 from the US and reflect the general population in the USA.

However, we cooperate with Cryos International and have donors with other ethnical backgrounds and phenotypes, such as Scandinavian.

The donors undergo rigorous selection criteria and thorough medical examinations prior to acceptance and clearance to become a donor. Donors pass a physical test and are screened for a battery of infectious and hereditary diseases, but despite being healthy young men, often students of higher education, only a small percentage pass to become a Cryos donor. A Summary of Records, containing test results and Standard release information, is attached to the order confirmation as well as included in all shipments. The Summary of Records is subject to change over time.

The Zika virus is a mosquito-transmitted infection related to dengue, yellow fever and West Nile virus known to cause severe birth defects in babies. Cryos continues to be very proactive in preventing the possible transmission of the Zika virus by implementing policies well in advance of the FDA requirements.  While the FDA has not approved a donor screening test for tissue banks, they have issued several Emergency Use Authorizations (EAU) for various test kits used to detect the Zika virus. These test kits are currently being used by blood banks, public health officials and physicians to screen patients for the virus.  In order to provide the safest donor sperm and eggs, all of Cryos donors who made deposits on or after August 1st, 2016 have now been tested.

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 semen is a consequence, which lead many patients to cross boarders ("fertility tourism") in order to receive treatment. In order to track these patients and pregnancies Cryos operate with a wordwide quota system**

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

*) The "national quota" is the maximum number of pregnancies 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). Siblings and abortions are not included.

**) "Cryos' “worldwide quota" is a general limit of 1 pregnancy per 200,000 citizens in the patient's country. Siblings and abortions are not included. This quota only takes into consideration the nationality of the patient not the country in which the patient is treated.

Example:
If a Finnish woman is treated in Finland, her pregnancy will count in the national quota which is 5 pregnancies (abortions and siblings not included) per donor. Her pregnancy will also count in the worldwide quota. If she is treated in the UK her pregnancy will neither have an influence on the Finnish nor the UK national quotas. However, it will influence the worldwide quota (1 pregnancy per 200,000 citizens in the patient’s country) which in this case is 26 pregnancies (Finnish citizens 5,223,442 : 200,000 = 26 pregnancies).

Our decision to make information about donors with suspected or known genetic conditions available to our customers is based on our desire to be transparent about these conditions. 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 are hidden in recessive form 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.

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 conditions or do you prefer NOT to know? Cryos leaves it up to you.

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.
This means that if we receive information about a possible hereditary condition in the donor or a donor child, the information will be assessed and if it is probable 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.

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

For ICI at a clinic or home insemination
We recommend using at least 2 x 0.5 ml straws with a minimum of 10 million sperm cells per ml. This can be achieved by using 2 x ICI MOT10 but we recommend that you use 2 x ICI MOT20 straws or higher motility per insemination. If the timing is correct, there is no need for more than one insemination per cycle.

IUI straws can be used for vaginal and cervical insemination if ICI straws of your favourite donor are not available. In this case you should use a minimum of 2 x IUI MOT10 straws or higher motility.

For IUI at a clinic
We recommend using 1 x IUI MOT5 or 1 x IUI MOT10 straw per treatment. If these straws are not available IUI MOT20 straws or higher can also be used.

ICI straws can also be used, if the sperm is prepared at your clinic prior to treatment. After preparation, there should be at least 2 million motile sperm cells per ml for IUI treatment.
If you use ICI straws we recommend 4 x ICI MOT5, 2 x ICI MOT10 or 1 x ICI MOT20 straw or higher, per treatment. If ICI donor sperm is to be prepared using the swim-up method, you should use 2 x ICI MOT20 straws or higher quality per treatment. We do not recommend using the swim-up method for donor sperm that has been frozen.

For IVF and ICSI at a clinic
Both ICI and IUI straws can be used. We recommend 1 x IUI MOT5 or 1 x ICI MOT10 straw. Higher qualities can also be used.

MOT is short for motility and means the sperms ability to move or swim. 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 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 analysed 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 (especially 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 Secutity Straws are specifically manufactured for safe cryo storage of biological products in liquid nitrogen. Directly after filling, both extremities of the CBS™ High Security straw are thermally sealed with one of our specific machines. 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.

Cbsstraw

 

CMV stands for Cytomegalovirus. It is a very common virus, which most people have before turning 50 years old. Approximately 50% of people aged 20 and approximately 90% of people aged 80 have been temporarily infected with this virus.

The reason why some of our donors have been screened for CMV is to accommodate use in some countries. It is only allowed to use sperm from a donation period when 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 an unborn baby is infected with CMV during pregnancy, there is a risk for the foetus. 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.

See Screening for further information.
