Sperm storage

    At Cryos you have the possibility to freeze and store your sperm for later use. There can be many reasons to why you would want to freeze and store your sperm. Common to all is the wish to preserve the possibility to have children later on in life.

    Cryos offers to freeze and store your sperm, so you can use it at a later time. Once the sperm is frozen it can be stored for the rest of your life (there is no expiration date). Freezing and storing of your sperm is what we call sperm storage.

    Sperm stored at Cryos for later use

    How to store your sperm 

    If you wish to have sperm storage at Cryos, please contact one of our departments in Aarhus, Aalborg, Copenhagen or Odense to make an appointment. When you arrive, you will be asked to fill out a form. You can also find and download the form below. The sperm sample can either be made at Cryos or in your own home. We just need the sperm sample within 1 hour after ejaculation. Glass containers for the sperm are available at Cryos. Remember to write your name and social security number on the label on the glass.   

    • Download  the form 

    Everyone who stores their own sperm falls under the “partner donors” category of the Danish Health Authority’s guidance because it is presumed that the sperm is going to be donated to a partner at some point. According to the guidance, all donors must be tested for anti-HIV 1/2, HBsAg, anti-HBc, and anti-HCV. The tests are mandatory. See the Danish Health Authority’s guidance nr. 9356 pct. 4.1 of 26.05.2015 for partner donors.  

    Worth knowing before storing your sperm

    • When making a sperm storage, a sexual abstinence period of 2-3 days prior to collecting the sperm is recommended.  
    • If the sperm sample is not made at Cryos, it is important that the sperm is kept at room temperature (20-30° C).  
    • Before ejaculation, the penis should be cleaned with water and without using soap.  
    • The sperm should be emitted directly into the glass container. Try to avoid spilling and be aware that the best quality of sperm is found in the first drops.
    • Condoms should not be used for collecting the sperm due to spermicidal supplements in the condom.
    • Interrupted intercourse in connection to sampling the sperm is not recommended due to the risk of spilling.  

    Renew your sperm storage online  

    You must choose a storage period for the sperm when you set up sperm storage. The minimum period is 3 months - see the table below for all options. The storage period can always be renewed online by using the username and password, which will be provided when the sperm storage is set up.  

    We will send you a reminder in advance, to notify you about the expiration date. The first reminder will be through e-mail. If we do not hear from you, we will send you another reminder by recommended letter. If you do not wish to receive reminders by e-mail, we will send them by recommended letter at a cost of DKK 250 (excl. VAT). 

    How to get your sperm delivered from the storage  

    You can request your sperm samples to be shipped from your online account. If you do not have access to a computer, you can fill out a delivery statement and send it by letter or fax to Cryos along with a copy of photo identification e.g. passport or driving license. Once the delivery statement is received, the delivery can take place. Please choose nitrogen tank as shipping method for your delivery. Find our shipping prices here.

    How to terminate your sperm storage  

    Your storage can be terminated online by using your username and password.

Once the termination statement is received, your storage will be terminated, and your straws will be destroyed.

    Unless you have a referral from a hospital with whom Cryos has a payment agreement, you will have to pay the cost of the sperm storage yourself. There are no grants from the Health Insurance or Health Insurance Denmark.
