How it Works

PLEASE BE ADVISED:  Cryobiology will be updating our website on or around July 20, 2019.  All account information will be transferred to the new site.  HOWEVER, you will need to update your password the first time you visit.  If you have any questions, feel free to contact us.  We are excited to launch the new site and hope it will enhance your experience with us.  Thanks!

Here is how it works:

  1. Cryobiology, Inc. recruits a diverse group of sperm donors from college campuses around the country. Becoming a Donor involves Semen Analysis, Medical History and Screening Questionnaire, Genetic Testing, certain Required Testing and follow up. The samples are subjected to a Quarantine Period of at least 180 days and then released for sale.  Less than 10% of potential donors are accepted into the program.
  2. Donor Search. Use this function of the website to filter donors according to traits that are important to you. You can immediately read a basic profile of each donor who meets your search criteria. You are not required to set up an account to use this feature.
  3. Choosing a Donor is a personal journey. Cryobiology, Inc. provides additional Donor Information to help you customize your selection. You must register and set up an account to access donor information and to purchase supplemental information.
  4. Purchase Donor Sperm by selecting an available Vial Type, Number and placing it in your shopping cart for payment.
  5. Select and purchase a Shipping Option.
  6. Sample Shipping will not occur until you and your partner (if applicable) have completed and returned the Sperm Use Agreement. This is done electronically.
  7. Samples will be shipped on the day that you specify. We do not recommend shipping on a Friday or before a holiday. Samples are packed in specialized nitrogen vapor (dry) shippers. Pickup may also be scheduled in the Columbus, OH area only.

Please Contact Cryobiology for additional information.

 Fertility Preservation Practical Matters

Men facing any circumstance that could impair their future fertility can choose to freeze (cryopreserve) and store their sperm samples for future use.  Indications for fertility preservation (click here for complete list) range from cancer chemotherapy to military service.

Preserving your future options to build a family involves knowing some important facts:

  1. Sperm samples should be frozen BEFORE treatment or exposure begins.
  2. Sperm quality varies with frequency of ejaculation and time from last ejaculation. Keep this in mind when scheduling your appointments for sperm freezing. We recommend at least 2 days, but not more than 5 days, of abstinence from ejaculation before collecting samples. In some cases, this may not be practical and we will still accept the sample for freezing.
  3. Plan to collect as many sperm samples as possible. While one sample is better than nothing, it may significantly alter your options in the future.
  4. If you are banking sperm prior to a military deployment or to accommodate frequent travel, multiple samples may be essential. Allow adequate time for rest (abstinence) days in between sample collections.
  5. Samples must be collected at one of our three locations. If we are not located near you, please call us so we can guide you to a registered sperm freezing facility near you.
  6. If you are physically unable to collect a sperm sample, there are surgical options for obtaining sperm under anesthesia. This surgical procedure must take place before you begin the treatment or exposure that will impair your fertility.  Please Contact Cryobiology for information.
  7. The quality of the final frozen sperm sample and the number of vials of sperm frozen may affect your options for using your frozen sperm in the future. Most couples using these samples will need to utilize Assisted Reproductive Technologies (like In Vitro Fertilization; IVF).
  8. There is a charge for freezing the sample and a monthly charge for storage (See Pricing or Contact Us).
  9. Samples can be collected by teens and boys as long as they are old enough to masturbate to ejaculation. Parental consent for freezing and storage is needed for men under 18 years old.
  10. Options for fertility preservation for male infants and pre-pubertal boys are limited.

Freezing and Storage of Eggs and Embryos for Fertility Preservation in Women is also available at our Columbus, OH location. Contact Cryobiology for more information.

Please see Vials Not Used and Future Donor Availability for additional information about special situations in Sperm Storage.

Vials Not Used

What happens if donor samples are sent to the physician's office and can't be used that month? Specialized equipment is needed to store frozen donor samples. Many physicians do not have this equipment in their offices. The samples are shipped in specialized nitrogen vapor (dry) shippers that maintain temperature for 7 (seven) days from shipping. Once a donor sperm sample is thawed it must be used immediately and cannot be refrozen by your physician. If you do not ovulate or cannot have an insemination that month, your samples must be stored in liquid nitrogen until they are used.

If your samples cannot be used with 7 days of shipping, they can be shipped back to Cryobiology, Inc. for storage. You are the owner of these samples and they will be placed in storage under your name. When you are ready to use them, the same samples can be shipped back to your physician. There is a charge for shipping.

PLEASE NOTE: Cryobiology, Inc. cannot restock vials or offer reimbursement for vials that have been shipped out of Cryobiology, Inc. However, we can store them for you, at your expense, until you are ready to use them.

Consult Your Physician

Cryobiology, Inc. wants to help you achieve your goal of having a healthy child as soon as possible. For this reason, we require that you be under the care of a physician or other health care provider in order to purchase donor sperm samples.

Consult your Physician for information about an important range of topics including:

  1. Preconception Testing or treatment that is recommended for you and your partner (if applicable). This consultation may include everything from recommended vaccinations to prenatal vitamins.
  2. Testing and information that will assist in selection of a sperm donor. For example, do you know your own blood type?
  3. Timing of your insemination including the best way to do it.
  4. Number of vials to order each cycle and when they should arrive at the Physician Office.
  5. When additional interventions or a visit to a fertility specialist may be needed to help you achieve a pregnancy.
  6. How to manage your pregnancy.

NOTE: Cryobiology, Inc. can assist you with donor selection and answer your questions about donor testing and screening. However, Cryobiology, Inc. does not offer medical advice or treatment management which can only be provided by a physician or other healthcare provider.                   

Genetic Testing

Screening Versus Testing for Disease. Sperm Donors are tested and screened for a variety of genetic diseases;  it is important for you to understand the difference. Donor screening indicates that the donor was questioned about family history, personal health history and other conditions that might suggest a risk factor for passing on a genetic disease. In some cases, screening occurs via a screening blood test that further identifies additional genetic disease risk. Most often, screening depends upon receiving truthful answers to specific questions, posed to the donor, that identify risk. When a donor is tested for a genetic disease, he has been subjected to a definitive test to see if he has a specific disease or is a carrier for a specific disease. Screening and testing are not the same!

Not all genetic diseases have definitive tests  available, so screening must be used to exclude donors at risk. However, neither screening nor testing can completely eliminate the possibility of passing on a genetic disease. For example, some types of Type 1 Diabetes run in families. Donors are screened for Type 1 Diabetes by asking them about their family and personal history. If they have Type 1 Diabetes themselves or a close family member has it, they are excluded from the donor program. However, this does not mean that a donor who has no history of Type 1 Diabetes in his family could not develop the disease himself or have a child who developed it.

Donors are not tested or screened for all genetic diseases. They are tested for some genetic diseases that are common in people in the general population or in individuals with their ethnic background.  For example, donors of Jewish descent are tested for some genetic diseases that are more prevalent in the Jewish population, including Tay-Sachs Disease, Canavans Disease and Familial Dysautonomia. Rarely, these diseases will occur in the non-Jewish population; however, the general population is not routinely tested for these diseases. On the other hand, diseases like Cystic Fibrosis and SMA are relatively common in the general population in the US.

We routinely perform the following genetic testing and screening on all sperm donors:

  1. Karyotyping
  2. Cystic Fibrosis
  3. Spinal Muscular Atrophy (SMA).

Screening for blood disorders such as Thalassemia and Sickle Cell Anemia via CBC and Hemoglobin Electrophoresis has been performed on all donors who were active after May 2001.  Donors previous to that were screened for those hemoglobin abnormalities only if indicated by the donor's ethnic background.

Donors with Jewish, Cajun and French Canadian background are tested for Tay-Sachs Disease.

Donors of Jewish Descent are tested for Tay-Sachs Disease, Canavans Disease and Familial Dysautonomia.

Potential donors who are adopted and do not know the genetic background of their biological parents are excluded from the donor program.

If you are affected by a genetic disease, are a carrier of a genetic disease or have a family history of a genetic disease, you can schedule genetic counseling for additional information and/ or possibly request additional donor testing. Please Contact Cryobiology for further information and cost.

Open or Anonymous Donor (Donor Anonymity)

Cryobiology (CBI) sperm donors fall into two categories, based on what they will disclose about their identity:

  1. Open Donors have agreed that they will permit their identity to be disclosed to a child that results from the use of their sperm once that child reaches the age of 18. The donor can change his mind about this disclosure at any time. Please note that identity disclosure does not extend to the woman who used the sperm (recipients).
  2. Anonymous Donors have decided not to disclose their identity to possible offspring or recipients and prefer to remain anonymous. 
Donors do not have the ability to contact you or your child.

The child of an open donor (who is at least 18 years old) who wishes to know the donor's identity must contact Cryobiology, Inc (CBI). CBI will contact the donor, determine if the donor still consents to have his identity revealed and then arrange for the contact between the donor and child.

In addition to their identity, Donors provide additional information about themselves that can assist you in selecting a donor. This information is described in the section entitled "Donor Information".

Note: Donors may change their mind about the information that they want to make public at any time. This may result in a change in their status on the website (change from open to anonymous or vice versa) or a change in the availability of certain Donor Information. You should consider this carefully when choosing the donor samples and donor information to purchase and/or download.

Donor Sample Quarantine

In the United States, banking of donor sperm is highly regulated for the safety of the recipient and resulting child. In particular, the Food and Drug Administration (FDA) determines conditions under which anonymous sperm samples can be processed and stored to prevent to the spread of communicable (contagious) diseases.

Anonymous Sperm Donors (all those sold by Cryobiology, Inc.) are tested for certain communicable disease agents (See Required Donor Testing for more Information) before they provide samples for freezing. These donor sperm samples must be quarantined a minimum of 180 days. At the end of 180 days, the donor is  re-tested for communicable diseases and, if the results are non-reactive, the samples can be released for sale. 

In point of fact, most samples released for sale have been quarantined longer than the 180 day minimum. The sperm donors have had multiple test panels performed before the release.Testing and quarantine ensures the safety of donor sperm samples.

 Types of Donor Sperm Vials

 At Cryobiology,Inc. (CBI), we process Donor Sperm into three types of vials:

  1. IUI (Intrauterine insemination) Vials were developed for use in Intrauterine Insemination (a specialized type of artificial insemination where sperm are placed directly into the uterus). IUI Vials do not contain seminal plasma (the liquid portion of the semen) so the vial can be thawed and used directly for intrauterine insemination without any additional processing.
  2.  ART (Assisted Reproductive Technology) Vials were developed for use in In Vitro Fertilization (IVF) and may require further processing. ICSI (Intracytoplasmic Sperm Injection) should be used with ART vials. We do not recommend the use of ART vials for IVF with standard oocyte insemination (without ICSI). Because ART vials contain fewer motile cells they may not be adequate for artificial insemination.
  3.  ICI (Intracervical Insemination) Vials were developed for use in intracervical insemination using a cervical cap. ICI Vials cannot be used for intrauterine or ART without additional processing since they contain seminal plasma.  Processing ICI Vials will reduce the number of motile sperm cells available for insemination. ICI vials are not available for all donors because this sample processing method was discontinued in September 1998. 
Note: All vial types are NOT available for all donors. See Donor Search for availability.

Required Donor Testing 

Sperm Donors are tested for communicable (infectious or contagious) diseases at the time of initial sample collection and at regular intervals while in the program. All samples are also subjected to a quarantine period of a minimum of 180 days with donor retesting before sample release.

All donors are tested for the following diseases:

  1. HIV 1 and 2 including NAT (Nucleic Acid testing).
  2. HTLV 1 and 2.
  3. Hepatitis B Antigen and Core Antibody including NAT
  4. Hepatitis C Antibody including NAT
  5. Syphilis
  6. Gonorrhea
  7. Chlamydia
  8. Cytomegalovirus (CMV Total; if positive, CMV IgM is performed).
The Food and Drug Administration (FDA) periodically updates the list of required testing for sperm donors. If a donor is not available to undergo new required testing, this may affect availability of samples. Cryobiology, Inc. stays abreast of all FDA Guidance and updates its donor screening and testing protocols as indicated.

Donors are also tested for certain Genetic Diseases and have extensive screening and testing before Becoming a Donor.

Vial Replacement Policy

LAB: Click Here for Sample Thawing Protocol

Cryobiology, Inc. is committed to providing a high quality cryopreserved donor sperm sample with a post thaw recovery you can count on!

Sperm count and estimation of motility are subjective processes and are known to vary by technician, training and experience, counting chamber used, thawing technique and even temperature. Always use our recommended Thawing Protocol.

Here is our guidance for Expected Post Thaw Recovery for comparison purposes only:

IUI (Intrauterine insemination) Samples.

  1. Volume: 0.5 ml.
  2. Approximately 20 million motile cells/ ml (+/ - 20%). Therefore, approximately 10 million motile cells/ vial.
  3. Minimum of 50% forward progressive motility.

ART (Assisted Reproductive Technology) Samples (Not Available on All Donors)

  1. Volume: 0.5 ml.
  2. Approximately 10 million motile cells/ ml (+/ - 20%). Therefore, approximately 5 million motile cells/ vial.
  3. Minimum of 30% forward progressive motility.

Note: ICSI (Intracytoplasmic Sperm Injection) should be used with ART samples; we do not recommend the use of ART samples for standard oocyte insemination in IVF (IVF without ICSI). ART vials are not recommended for use in artificial insemination since they contain fewer motile sperm than IUI vials.

ICI (Intracervical Insemination) Samples (Only Available on Donors Frozen Before 1998)

  1. Volume: 1.0 ml.
  2. Approximately 30 million motile cells/ ml (+/ - 20%). Therefore, approximately 30 million motile cells/ vial.
  3. Minimum of 40% forward progressive motility.

Note: ICI samples cannot be used for intrauterine or ART without additional processing since they contain seminal plasma. Processing will reduce the number of motile sperm cells available for insemination.

Replacement Procedure: If samples appear to contain significantly fewer motile sperm cells than described above, please Contact Cryobiology immediately. We will:

  1. Obtain a complete lab report on the sample from the lab processing the sample for review by the Cryobiology Quality Assurance Department.
  2. If indicated, replace an inadequate vial for the next cycle if the patient is NOT pregnant and provided the samples were shipped within the last three months. (No replacements will be provided for samples that were shipped more than three months ago).

NOTE: Shipping costs are not included in the replacement.

CMV, Zika and Other Viral Diseases

Cytomegalovirus (CMV) and Zika virus are just two examples of viruses that can be sexually transmitted and can have a profound effect on a developing fetus when a pregnant woman is infected. The FDA (Food and Drug Administration) sets standards for screening and testing for certain viral diseases in men who are sperm donors.

Cytomegalovirus (CMV) is a viral disease that is relatively common in the normal population, particularly among those with routine exposure to children. Most people who are infected with CMV have no symptoms and develop antibodies to the virus with no further consequences. Others have mild flu like symptoms. Antibodies to CMV can be detected with a blood test: CMV Total. A positive CMV Total indicates that a person has been exposed to the virus at some point in the past.

However, if a pregnant woman is newly and actively infected with CMV, the virus can cause birth defects and other complications in a developing child. The presence of CMV IgM in the blood signals a recent and active infection.

The FDA mandates that all anonymous sperm donors be tested for CMV Total to determine if they have been exposed to CMV at any time in the past. If the CMV Total test is positive, the donor is tested for CMV IgM. If the CMV IgM is positive, it means that he is actively infected and cannot donate sperm until the situation has resolved. If the IgM is negative, it means that the donor has been exposed to CMV in the past but is not currently actively infected or contagious. It is important to note that a donor who tests negative for CMV but who develops a new infection may take several weeks to turn CMV positive. 

There is no such CMV testing requirement for a woman attempting to conceive or her sexually intimate partner. If a woman develops CMV during her pregnancy, she likely was exposed to the virus herself or via her partner. While it is theoretically possible that an infection could come from a donor, donors are tested regularly for CMV.

You should consult your own physician about your need to be tested for CMV and how your results might affect your choice of donors. Some physicians recommend testing all women for CMV and, if they are CMV negative, suggest (in an abundance of caution) that they only select a donor who is also CMV negative. Other physicians make no such recommendation. In these centers, women may be tested for CMV but, with the knowledge that anonymous sperm donors are regularly tested, are counseled that CMV status need not be a donor selection criterion.

Zika virus is a mosquito born viral disease that is currently prevalent in Mexico, Central and South America and the Caribbean. It will likely reach the US this summer as mosquito season gets underway. Like CMV, people with Zika often have few or no symptoms. However, if a pregnant woman is infected with Zika there may be significant consequences for her unborn child. Furthermore, Zika is sexually transmitted thus increasing the risk of exposure for pregnant women.

There is no readily available blood test for the Zika virus. Protection from the virus comes from screening (questioning) individuals for risk factors for Zika virus. Current FDA Guidance suggests that women who have traveled to Mexico, Central and South America and the Caribbean with or without symptoms of Zika virus should defer pregnancy for 8 weeks after possible exposure. A man (sexually intimate partner) who has traveled to the same area should use a condom during intercourse for a minimum of 8 weeks if he had no Zika symptoms and for 6 months if he had any fever or flu like symptoms. The virus is carried in the semen (liquid portion of the ejaculate) not in the sperm itself so even men who have a vasectomy are at risk of transmitting the virus.

Currently, the FDA requires that all anonymous sperm donors who have traveled to Mexico, Central and South America and the Caribbean be deferred from freezing new sperm samples for at least 6 months after their trip. This may affect the donor sperm supply for some time to come. Please keep this in mind in selecting and reserving your donor samples.

From time to time, the FDA issues guidance to screen sperm donors for their risk for other viral diseases that can be sexually transmitted. For example, men are screened for possible exposure to West Nile Virus (WNV) during the US mosquito season. In the past, men were screened for Swine Flu risk.

Cryobiology, Inc. stays abreast of all new Guidance from the FDA about communicable disease risks and donor sperm policies and updates its donor testing and screening procedures as indicated. Our goal is to provide high quality and safe donor sperm.

Choosing a Donor

Choosing a sperm donor is a personal process. Cryobiology, Inc. provides tools to help you make the best choice to build your family:

  1. Donor Search allows you to filter donors according to traits ranging from ethnicity and religious background to appearance and blood type. You can do this in privacy without registering or creating an account. 
  2. Supplemental Information is available free of charge once you register and create an account. You can narrow your search using the basic profile, Medical History,"In Your Own Words" an essay written by the donor (where available) or a donor silhouette.
  3. Additional Information is available for purchase to further customize your search and to keep for the future when you achieve a pregnancy. This includes current and childhood photographs, audio interviews or Keirsey Personality Profiles.
NOTE: All sperm donors are required to submit to physical exams, screening and testing for communicable diseases and a complete medical history before being admitted to the donor program. This process is repeated regularly. Donors are not required to provide any information that could identify them and must give written consent for release of this information; therefore, not all supplemental information is available for all donors.

See the Services Section of this website, Donor Information for instructions on download and/or purchase of supplemental materials.

For Additional Information on Donor Testing and Screening please see: Donor Medical History, Required Donor Testing, Sample Quarantine, Genetic Testing and CMV, Zika and Viral Diseases.

Choosing a Sperm Donor by Blood Type (Click Here for a PDF of this Section)

Blood type of the donor will be an important characteristic if you are undecided if you will tell your child that he/she was conceived using donor sperm. Some couples will want to ensure that their child does not have a blood type that would be biologically impossible if the male partner were the father.

If you have chosen to be open about your decision to use donor sperm or do not have male partner, the blood type may not be as important in donor selection. However, if you (the recipient) have an Rh Negative blood type, your doctor may recommend that you choose a donor that is RH negative, if possible. In any case, if you are Rh negative, you should notify your obstetrician of the donor’s blood type as specialized treatment may be required when there are differing Rh Factors.

Here is a chart for your use in determining blood type, if you choose to use it as a selection tool.

If the Couple's blood types are:The Donor's blood type may be:
A and AA or O
A and BA, B, or O
A and OA or O
B and BB or O
B and OB or O
O and Omust be O

If the recipient is AB and the male is:The Donor may be:
Aany type
Bany type
Omust be O
ABany type

If the male is AB and the recipient is:The Donor should be:
A*AB but not O
B*AB but not O
O*AB but not O
ABany type

*A or B could be used, but if the donor and the recipient both contribute the gene for O, the child would be O. A child with a O blood type could not have biologically come from this couple. Keep this in mind, if a suitable AB donor cannot be found.

Please note:  Matching of blood types does NOT necessarily guarantee that either partner will be able to donate blood and/or tissue to the offspring.  Rh factors will be the determining factor in those situations many situations. Inheritance of Rh factors is difficult to predict without complete family histories of both the male and female partners.

Donor Medical History and Screening Questionnaire

Donor Medical History is an important screening tool in selecting donors. Each donor provides a three generation medical history as part of his initial application. If a potential donor is adopted and does not have knowledge of the medical and genetic history of his biological parents, he is excluded from the donor program.

History of certain diseases in the donor or his immediate family automatically exclude him from becoming a sperm donor (e.g. Type 1 Diabetes, schizophrenia, Huntington’s Disease, to name a few). The medical history may also suggest a need for additional follow-up questions.

Each potential donor also responds to a Donor Screening Questionnaire to determine if he has any lifestyle, health or even travel history factors that suggest that he is at risk for communicable diseases. For example, men who have traveled to the Caribbean, Central and South America and Mexico in the recent past may not be eligible to donate semen due to the risk of Zika Virus.

Cryobiology accepts less than 10% of men who apply to become sperm donors based on regulatory, logistical and availability issues. This selectivity is designed to ensure that donor sperm samples are of the highest quality and meet safety requirements to protect both the recipient and the resulting child.

Limit on Pregnancies by Donor

Cryobiology, Inc. places a limit on the number of pregnancies for each donor based on both geography and on absolute number of pregnancies. Our goal is reduce the risk of inadvertent intermarriage of siblings in the future and to always be aware of any previously unsuspected health issues or genetic diseases in donors or their offspring. However, we can only achieve this goal if patients and physician offices are diligent in reporting pregnancies and their outcomes. 

Pregnancies can be reported on line using our Report a Pregnancy function. These results are routinely reviewed for trends that may indicate that a particular donor:

  1. Should be restricted in a given geographic area.  This Geographic Restriction is indicated in Donor Search and Donor Purchase.
  2. Has reached the maximum number of pregnancies and must be taken out of use.
  3. Has a pregnancy history that suggests a need for follow up on certain health or genetic disease issues.

Geographic Restrictions 

A donor may become geographically restricted for sale when his sperm has been used to achieve ten pregnancies or if a pre-determined population count has been reached. 

A woman (recipient) or couple may purchase donor sperm in cases of Geographic Restriction in cases where Sibling Pregnancy Attempt is desired.

Please Contact Cryobiology if you have found a donor that has a geographic restriction in your city and state for more information.

Future Donor Availability

Donors only provide samples for a limited period of time. Therefore, future availability of donor samples and donor information is not a certainty. A donor is labeled as Limited Availability when the number of vials available for sale dwindles.

If you wish to use the same donor for future sibling pregnancies, we recommend that you purchase additional donor vials for storage at Cryobiology, Inc. Advance purchase and storage at Cryobiology ensures future availability to you and safe storage for the samples.

Restocking. In some cases, samples that have been stored at Cryobiology, Inc. and are not used can be returned for partial reimbursement. We cannot offer reimbursement for any vials that have been shipped out of Cryobiology.

Cryobiology, Inc. also maintains a Donor Waiting List. If a particular donor is no longer available, you can be placed on this list in case vials become available.

Donor Information may only be available online while donor samples are also available for sale. If you wish to purchase donor information, it is best to do so when choosing a donor or when a first pregnancy is achieved.

Please Contact Cryobiology for additional information.
