    At Cryos we have more than 35 years of experience with sperm donation. A lot has happened through the years, and especially the development and recognition of new family structures has increased the importance of sperm donation. Today, sperm donation is widely used by women and couples all over the world as a help to achieve pregnancy.

In other words, we work hard to ensure quality in every step of the process – from screening of sperm donor candidates to correct use of donor sperm in fertility treatment at your clinic. Read on to learn about the different steps of the sperm donation process.

    The sperm donation process

    Many people are surprised to learn exactly how thoroughly we screen all sperm donor candidates before accepting them as Cryos sperm donors. Becoming a sperm donor is not something that anyone can do – in fact, only about 5-10% of all sperm donor candidates live up to our sperm donor requirements and eventually become donors. In the following, you can learn more about the different steps that each sperm donor goes through before the actual sperm donation.

    Step 1: Applying as a sperm donor

    First, a potential sperm donor must fill out an application form with basic information and contact info and then book an appointment for a preliminary sperm sample.

    Step 2: Preliminary sperm test and analysis

    The sperm donor candidate visits one of our sperm bank locations and provides a preliminary sperm sample. This is of course a very important step, as we want to make sure that his sperm can survive the freezing and be able to fertilize an egg later on. To measure sperm quality, we look at the motility (MOT). Read more about sperm motility and what it means for your fertility treatment.

    Step 3: Clinical examination and family medical history

    If his sperm quality is good, and he lives up to our preliminary sperm donor requirements, the donor candidate will undergo a clinical examination. The purpose of the clinical examination is to ensure that there are no physical signs of diseases, and a health professional will therefore thoroughly check the sperm donor candidate’s skin, lymph nodes, blood pressure, BMI, etc.

    Before the examination, the candidate must complete an extensive questionnaire regarding his and his family’s medical history. The questionnaire will then be discussed with a health professional in relation to the physical examination to check whether there is any history of serious hereditary mental or physical diseases. We will also ask for blood and urine samples to test for infectious diseases such as HIV, chlamydia, etc. and common genetic variants causing cystic fibrosis and other frequent, serious hereditary diseases. If you want to know more about the different tests, you can read more on our page Screening of sperm donors.

    Step 4: Psychosocial interview

    Besides their physical health, we want to make sure that the sperm donors are mentally healthy and understand the meaning of sperm donation. During a psychosocial interview with our in-house psychologist, the donor candidate will be asked about his motivations, ethical considerations, openness, and expectations.

    Step 5: Sperm Donor Profile choices and questionnaires

    During the screening process, the sperm donor candidate will be informed about the difference between being an ID Release or Non-ID Release sperm donor as well as having a Basic or Extended Donor Profile, and he will be asked to decide which type of sperm donor he wants to be. If he chooses an Extended Profile, he needs to fill out another questionnaire with questions about his life experiences, preferences, personality, etc. and send in child photos, a handwritten message, and a voice recording. ID Release sperm donors also sign different consent forms allowing their identifying information to be shared with donor-conceived children later on.

    Step 6: Approval - the sperm donation can begin

    If the donor fulfils the sperm donor requirements and passes all tests and screening, he will be approved as a sperm donor. Only then can he begin the actual sperm donation and help others achieve their dream of a child. The sperm donor commits to delivering at least 10 approved sperm donations, which is referred to as a batch. Before and after every batch, the sperm donor must have his blood and urine tested to make sure that he has not caught any infectious diseases. If the tests look fine after completing a batch, the sperm will be released for purchase via the Sperm Donor Search on our website, and the sperm donor will receive his compensation. He can then decide if he wants to continue the sperm donation and commit to another batch.

    From sperm donation to freezing in straws

    Once a sperm donor candidate has been approved for sperm donation, he commits to delivering 10 sperm donations within a period of approximately 10 weeks. The actual sperm donation takes place at one of Cryos’ sperm bank locations. Here, we have private donor cabins where the sperm donor goes in to donate. Afterwards, the sample is handed over to the staff and instantly taken into our laboratory, where we will thoroughly check the sperm quality to ensure that only high-quality sperm is distributed from Cryos.

    If the sperm quality is good, the sperm will be further processed in the lab before it is put into so-called straws of 0.5 ML that are easy to freeze, store and thaw. All donor straws are clearly marked with the sperm donor name or number as well as the ejaculate number and categorized according to the type and quality of the sperm.

    At Cryos we offer two types of donor sperm: IUI and ICI. IUI donor sperm can be used for most fertility treatments, as this has been washed and prepared for use. ICI donor sperm is unprepared and contains all the natural fluids present in a normal ejaculate. This is ready to use for ICI treatment, but must be washed by your fertility clinic if used for other treatments such as IUI or IVF.

    Furthermore, the donor sperm is divided according to motility, which is an expression of the quality or concentration of sperm cells. The higher the sperm motility, the more active sperm cells are.

    Finally, the donor sperm is kept frozen and safely stored in a nitrogen tank at -196 °C, until it is purchased by someone who has decided to get pregnant with donor sperm.

    Shipping and use of sperm donations

    When we receive an order of donor sperm, we will carefully move the donor sperm straws from our tank and into a smaller container or tank that will keep the sperm frozen and safe during transportation. A courier company will deliver the order to your clinic, which checks and signs for the delivery. You can read more about the shipping and delivery of donor sperm here.

    Once it is time for your fertility treatment, the donor sperm will be thawed at room temperature. This takes about 15-20 minutes, and immediately after, your clinic must perform a microscopic sperm analysis to check that the sperm quality is as expected. After that, the sperm is ready for use in fertility treatment such as IUI or IVF.

    Who benefits from sperm donation?

    Donor sperm from Cryos is used for different reasons and by people all around the world. About 50% of the women ordering donor sperm from Cryos are single mothers to be, who choose sperm donation because they have not found the right man yet or simply want to raise a child on their own terms.

    Another 35% are lesbian couples, for whom sperm donation is a unique opportunity because one of the women in the relationship will have a genetic relation to the child.

    Finally, infertility is a common problem and approximately 15% of all couples who are trying to conceive seek help. Because of different factors, the number of couples experiencing infertility has increased through the years. When dealing with infertility as a heterosexual couple, the option of conceiving through sperm donation allows a genetic relation between mother and child.

    Frequently asked questions about sperm donation

    How much do you get paid for a single sperm donation?

    The compensation a sperm donor receives for a single sperm donation is between 200 - 500 DKK (28 - 67 Euro). The amount depends on different factors like sperm motility, choice of Donor Profile, and amount of sperm donated.

    Can you make sperm donations anonymously?

    Yes, sperm donors can donate their sperm anonymously. If, however, a sperm donor chooses to be an ID Release Donor, he accepts that children conceived from his sperm donations can contact Cryos at the age of 18 and receive identifying information about him. A Non-ID Release Sperm Donor, on the other hand, wishes to remain anonymous. 

    Why do men donate their sperm?

    The sperm donors at Cryos donate their sperm because they want to help others achieve their dream of a child. Some of them have a close family member or friend who has struggled to have children, and others are parents themselves. The compensation is a chance to earn a little extra but is not the primary reason and the motivation to donate.
