Initially our donors are selected by our sperm bank staff, based on a number of parameters:
- Sperm Quality
- Age
- Personality
- Education
- Criminal Background Check
- 4 Generation Family Health History
Further screening includes blood and urine analysis:
- Physical Exam every 6 months (including EKG)
- Chemistry Panel
- Complete Blood Count
- Urinalysis
- ABO-Rh Blood typing
- HIV
- HTLV I/II
- Hemoglobin Fractionation
- Hepatitis B Surface Antigen
- Hepatitis B Core Antibody
- Hepatitis C Viral Antibody
- Syphilis
- CMV IgG/IgM
- Chlamydia
- Gonorrhea
The genetic testing we do includes the following:
- 4 generation family medical history, which is reviewed by a trained genetic specialist and a medical doctor (all donors)
- Cystic Fibrosis screening
→ Up to 97 mutations on donors with optional advanced testing.
→ 32 standard mutations tested on all donors include:

- Chromosome analysis (all donors)
- Spinal Muscular Atrophy (SMA) (all donors)
- Sickle Cell Disease. For all donors a Hemoglobin Fractionation analysis is done to detect this indirectly.
- Thalassemia (all donors). A Hemoglobin Fractionation analysis is done to detect this indirectly. Please contact us if you would like to have your donor genetically screened for carrier status.
- Bloom Syndrome (donors with Azhkenazi Jewish Ancestry)
- Canavan disease (donors with Ashkenazi Jewish ancestry)
- Familial Dysautonomia (donors with Ashkenazi Jewish ancestry)
- Fanconi Anemia type C (donors with Ashkenazi Jewish ancestry)
- Gaucher disease (donors with Ashkenazi Jewish ancestry)
- Niemann-Pick type A disease (donors with Ashkenazi Jewish ancestry)
- Tay-Sachs disease (donors with Ashkenazi Jewish or French Canadian ancestry)
Extended Genetic Testing:
Seattle Sperm Bank is proud to offer Counsyl’s Universal Carrier Screening (102 conditions tested) on all donors who entered our program since August 2016!
Over the years, we have expanded our genetic testing of donors as genetic knowledge and technology continue to advance. As a result, not all donors have been tested for the same conditions or with the same methods. However, all donors have undergone screening and testing for the conditions listed here, if not more.
