The Clínica Tambre sperm bank was the first to be opened in the Community of Madrid and the second in Spain.
With more than 40 years of experience, hundreds of sperm donors have already made their contribution here. We are the leading sperm bank in Madrid thanks to our professionalism, central location, and flexible working hours which let you choose the day and the time that best suit you for a visit.
What is sperm donation?
Sperm donation is an anonymous, confidential, and altruistic act that makes treatment possible for couples in which the male partner has low sperm quality or runs the risk of passing on a genetic defect, or for women who wish to become pregnant but who do not have a male partner.
Who can be a sperm donor?
Any male over the age of 18 that is in good health The process begins with a first visit where the donor will be thoroughly informed about the donation procedure and any questions he may have will be answered. During this interview the donors will also fill out a basic health questionnaire. Afterwards, candidates will undergo multiple tests to ensure that they are physically and mentally healthy, these include a psychological evaluation, blood tests and sperm analyses.
How long can I be a donor for?
You can stop donating whenever you want or when the maximum number of pregnancies permitted by law has been exceeded.
After 3-5 days of sexual abstinence, the donor will provide a sample by masturbation at the Clinic, which will be collected in a sterile container and under aseptic conditions.
Gamete banks as well as the clinics’ donor and activity registers are obligated to guarantee the confidentiality of the donor’s identity information.
Reimbursement for expenses and inconveniences
Without prejudice to the altruistic and non-profit nature of sperm donation, donors shall be solely reimbursed for physical inconveniences and work and travel expenses that may result from the donation. This reimbursement, however, shall not provide any financial incentive.
Legal considerations for sperm donation
The legal framework regulating human assisted reproduction is primarily comprised of the Spanish Law 14/2006, of the 26th of May on human assisted reproduction techniques.
- Donating gametes is a formal, confidential, and free contract entered into between the donor and the authorised clinic. Gamete banks as well as the clinics’ donor and activity registers are obligated to guarantee the confidentiality of the donor’s identity information.
- Donations can only be withdrawn if the donor himself needs the donated gametes and only if these are available on the date on which he wishes to withdraw them. Upon withdrawal, the donor will return all expenses reimbursed by the receiving clinic.
- The maximum authorised number of children who may be born in Spain from gametes from the same donor shall never exceed six. To effectively maintain this limit, at each donation donors must declare whether they have made any previous donations and under what conditions, indicating when they made the donation and to what clinic.
The authorised clinics may reject a donation when the donor’s psychophysical conditions are not suitable. In the event that a donor was not accepted for said reasons, he would be entitled to know the reasons for his exclusion while guaranteeing the privacy and confidentiality of said information.
I’m already a sperm donor.
Accepted donors will select a day of the week (whichever works best for their schedule) to come into the Clinic and donate. Holidays are observed.
General requirements for becoming a sperm donor:
Donors must be older than 18, physically and mentally healthy, and have full capacity to act. The average age of our donors is 23 years old. Donors will undergo a medical examination which includes their personal and family medical history and consists of a physical and a psychological evaluation along with the following tests:
- Semen Analysis
A sperm sample will be collected after a minimum of 3 days of sexual abstinence. We need a minimum of 2 normal semen analyses in order to be able to accept a donor. This is the easiest test to perform and this initially determines whether a donor will be rejected or not. In addition to measuring sperm count, motility, and morphology, we also retrieve motile spermatozoa after capacitation. Although the World Health Organization has published a Manual in which the minimum values needed to consider a sperm sample normal have been determined, we don’t accept any donors who have a sperm count below 70 million spermatozoa per ml and whose sperm have less than 60% motility.
If the semen analysis is accepted, the next test will be:
- Sperm Freezing:
to see how well the spermatozoa respond to freezing.
If this test is also accepted, the following information will be collected with a blood test (blood is drawn only once):
- Blood type, Rh factor,
- VDRL or a similar test for detecting syphilis,
- hepatitis serology, detection of HIV indicators,
- clinical exam for detecting neisseria gonorrhoeae and chlamydia trachomatis,
- general analyses (blood count, biochemistry),
- genetic analysis (karyotype).
The final test is a semen and urine culture, to rule out any type of infection. Several of these tests will have to be done every three months because frozen sperm cannot be used until six months after donation (or two check-ups with negative results).
Finally, the donor must sign an informed consent form that explains the entire process and the tests that he’ll undergo.
