Screening of donors


SellmerDiers Sperm Bank guarantees that donors have been selected and screened in accordance with the current quality and safety standards. The purpose is to exclude donor applicants with pathogenic organisms, infectious diseases, genetic diseases etc. that may constitute a risk of disease to the Customer or any donor child.

Donor applicants go through an extensive approval procedure according to applicable rules, the recommendations of the Danish Health and Medicines Authority and the Clinic's internal standards.

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
- chlamydia
- gonorrhoea
- syphilis
- 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.
