Clínica Tambre has the oldest sperm bank in Madrid and it is one of the oldest in Spain. Its founder, Dr. Caballero, began his work more than 40 years ago, adapting to the advances which have been made in Assisted Reproduction over the years
Before being accepted, each and every one of the donors undergoes the prior examination as outlined in the legislation. We also include additional tests in order to make the screening process more extensive:
- Personal interview and medical history.
- Two semen analyses.
- Freezing / thawing
- Semen and urine culture (Stamey test: first-voided urine, last-voided urine, prostate and urethral secretions, and semen with a ureaplasma and chlamydia analysis)
- Psychological evaluation
- General analyses including a test to detect sickle cell anaemia.
- Serology: HIV, Hepatitis B y C, Syphilis.
- Karyotype. To rule out any hereditary diseases or chromosome abnormalities.
- Cystic fibrosis and Beta Thalassemia. Although this is not one of the tests we are obligated to perform as a Sperm Bank, our clinic chooses to carry out a more thorough examination since these two diseases are more common among the Mediterranean population
- Periodic check-ups. It’s very important that donors have periodic serology and microbiology check-ups. According to the Spanish Law on Assisted Reproduction, sperm may not be used until it has been tested negative for HIV twice and therefore we perform these tests every three months.
