At Institut Marquès we have our own Premium Sperm Bank and vast experience in donor selection. The donor is personally chosen by the doctor to guarantee the most suitable for each patient. The matching process takes into account both the blood group and the RH as well as the physical features of future parents (eye, hair and skin color, etc …). Donors undergo a thorough sociological and psychological assessment and a full medical check-up and blood works, including the study of their karyotype, several tests to rule out infectious diseases and specific tests to rule out the most frequent mutations in the European population. They also perform blood tests that are repeated periodically to detect sexually transmitted diseases. Moreover, the family medical history is reviewed to discard possible genetic illnesses. Finally, they undergo tests to rule out any chromosomal abnormalities in the ejaculated sample (FISH in sperm) and to detect the 50 most common cystic fibrosis mutations. According to Spanish legislation, semen donors must be between 18 and 50 years old.
