The selection criteria in this procedure include:
- donor age
- assessment of risk behaviour
- donor interviews
- completion of questionnaires
- possibly review of medical records to determine the medical history of the donor applicant and his family
- a physical examination
- assessment by a specialist in human genetics
Sperm, blood and urine sampling with a view to testing sperm quality and for a wide range of infectious and genetic diseases
- hepatitis B
- hepatitis C
- chromosomal analysis
- cystic fibrosis
- blood type.
In addition, donors are tested and examined for infectious diseases on an ongoing basis during the entire donor period.
Screening for DNA fragmentation
SellmerDiers Spermbank screens for DNA fragmentation in all donor candidates. If the DNA fragmentation is too high, it will have a major impact on the donor's fertility. If DNA fragmentation is above 15%, the possibility of a successful pregnancy is significantly compromised in spite of good sperm quality, and successful pregnancies will often result in abortions. All donor applicants with DNA fragmentation above 15% are rejected.
