Anonymous or Non-anonymous and Basic Profile or Extended Profile.


1. Fill out the application form

You can fill out the online application form here.

2. Preliminary sperm samples

Once you have submitted your application, you will be contacted by one of our employees who will explain the next procedure. To begin with, you must provide 1–3 preliminary sperm samples. You can provide your sperm samples whenever it suits you, as long as it is within our opening hours.
To ensure good sperm quality, you should not have ejaculated in the last 2–3 days prior to arriving at the sperm bank.


3. Donor agreement and clinical examination

As soon as the third sperm sample has been provided, the decision will be taken as to whether your sperm quality meets the approval requirements. You will be contacted about the results. On approval, you will be requested to complete an online questionnaire about your health. A health professional will review your responses.

We will then agree on a time for you to fill out the donor agreement and undergo a clinical examination, where among other things, urine and blood samples will be taken. Remember to bring valid ID in the form of a passport or driving license.

4. Approval

The health professional will carry out a preliminary approval. Once the results of the urine and blood tests have been received, you will receive a final approval. You will receive up to DKK 500 for every approved donation as compensation.


Quarantine before your sperm is released

As an approved sperm donor, you must provide at least 10 approved samples (= one batch) in maximum 10 weeks. Only then can the sperm be released for use. Once the first batch is completed, you simply start a new batch.
