Who can be a sperm donor?

Any male over 18 years of age in good physical and psychological health.

Donors will have to undergo a medical examination, including their personal and family history, which will include a physical and psychological examination with the following tests:

The process begins with a first visit in which the donor is thoroughly informed about the donation and all possible doubts are solved. In addition, a basic health questionnaire is conducted during this interview. Afterwards, different psychological, blood and specific semen tests will be carried out to ensure the good physical and psychological condition of the candidates.


When you contact us, our patient care staff will set up an appointment with our donation program team, giving you a convenient date and time. In it, our team will conduct a short and pleasant interview consisting of questions about your personal and family health. They will also tell you, in detail, how the donation process works and will answer all your questions without any kind of obligation.

Once all your doubts are resolved, you will receive written informative documentation together with the informed consent of the technique. You will have all the time you need to think about whether you decide to go ahead with the process, just call us or send us an email confirming your acceptance.

Interview with the psychologist

These treatments have an important psychological component and we always look after the physical and psychological safety of our donors. Therefore, this interview with our psychology team will be a pleasant time to chat and rule out any type of pathology that could be transmissible to the offspring.

Medical tests

Once you have passed the interviews, we will begin the process and for this it will be necessary to perform some simple medical tests to confirm that you are in perfect health and that you are not exposed to any risk.

The tests that the nurses and embryologists will perform will be:


It describes and indicates the state of your chromosomes (with a simple blood sample).

Genetic analysis

With a small blood sample, we can test for more than 600 possible genetic diseases and we can rule out possible diseases in your genes.


A simple sample can rule out diseases or infections in your current health, such as hepatitis, AIDS and syphilis.

Semen quality study

You must provide us with an initial semen sample that will be evaluated in the andrology laboratory by the embryologists. They will analyze total sperm concentration, motile sperm count and sperm morphology.

If the fresh quality is good, a survival test will also be performed to see what % of them survive freezing and a motile sperm recovery test (REM) to analyze their capacitation behavior.

Sperm DNA fragmentation study

One of the samples you provide will be sent to us for analysis to determine the degree of fragmentation of the DNA of your spermatozoa.

Study of sperm DNA aneuploidies

Through this analysis of your sperm we can know if the chromosome endowment is correct or if there is excess or defect of any of them.

Semen and urine culture

To rule out any type of infection. As with serological tests, they will have to be performed every three months because semen that has been frozen cannot be used for six months (or two negative controls).

All these tests are free of charge and can help you to know your health status when you want to become a father. In addition, we will provide you with a copy of all the results.

Donation process

A semen sample should be collected after 2-3 days of sexual abstinence. We need a minimum of 2 normal seminograms in order to accept a donor. This is the simplest test to perform that discriminates in principle whether it is rejected or not. In the semen analysis, in addition to the count, motility and morphology, we perform the recovery of motile spermatozoa after capacitation conditions. Although the World Health Organization has published a Manual with the minimum values to consider a semen sample within normality, we do not admit donors below 70 million spermatozoa per ml and 60% motility.

If the semen analysis is accepted, the next test to be performed is semen freezing: to find out how the sperm respond to freezing.

If everything is ok, donations begin. They must be performed in the special room at the ERGO Clinic to control the identity and asepsis of the sample.

Donations are made 1 day per week with sexual abstinence of about 2-3 days and are collected in a properly identified aseptic jar. The total donation process takes approximately 2 to 3 months depending on the quality of the sample. You can set the day of the week and the time that suits you best and the showroom will be reserved for you.

What law regulates sperm donation?

The legal framework regulating assisted human reproduction is mainly constituted by Law 14/2006, of May 26, 2006, on assisted human reproduction techniques.

  • Gamete donation is a free, formal and confidential contract between the donor and the authorized center. Both the gamete bank and the registers of donors and activity of the centers are obliged to guarantee the confidentiality of the donors’ identity data.
  • The donation can only be revoked when the donor needs the donated gametes for himself, provided that they are available on the date of revocation. Upon revocation, the donor shall reimburse the recipient center for all expenses incurred.
  • The maximum authorized number of children born in Spain that would have been generated with gametes from the same donor must never exceed six. For the purposes of effectively maintaining this limit, donors must declare in each donation whether they have made other previous donations, as well as the conditions of these, and indicate the time and the center where these donations were made.

In any case, the authorized centers may refuse the donation when the donor’s psychophysical conditions are not adequate. In the event that a donor is not accepted as such, he/she will have the right to know the reasons for his/her exclusion, guaranteeing the confidentiality and privacy of the information.
