Donor Screening Process

TSBC screens all sperm donors in accordance with parameters recommended by the FDA, the American Society for Reproductive Medicine, the American Association of Tissue Banks, and the Centers for Disease Control and Prevention. We use only cryopreserved (frozen) semen, and all sperm samples are quarantined for a minimum of six months before they are released, so that we may thoroughly screen donors for sexually transmitted diseases. For a listing of all the Screening Tests that we do please click on this PDF: Screening Tests 2011

Clinical Evaluation of Donors Before Approval
• One complete semen analysis; three to five sperm counts and post-thaw evaluations.

• A four-generation medical and genetic history self-reported during a personal interview (medical history of donor, his children, siblings, parents, and grandparents).

• HIV risk assessment interview, based on sexual activity and drug-use history.

• Blood and urine testing for infectious diseases: HIV-1/2, HTLV-1/2, hepatitis B, hepatitis C, syphilis, gonorrhea, chlamydia, CMV (cytomegalovirus).

• Blood and urine testing for blood typing and general health indicators: ABO/Rh typing, CBC (complete blood count), liver panel, chemistry panel, and urinalysis.

• All donors receive genetic testing for Cystic Fibrosis carrier trait. All donors are tested by Hemoglobin Electrophoresis to determine Sickle-cell and Thalassemia carrier status and identify other hemoglobin-related blood disorders. Donors of Jewish, French-Canadian, or Cajun descent also received genetic testing for Tay Sachs carrier trait.

• Complete physical examination.

Clinical Evaluation of Donors After Approval
• A sperm count and post-thaw evaluation is performed on every sample to ensure that it meets our post-thaw minimum of 20 million motile sperm per cc.

• Quarterly testing for HIV-1/2, HTLV-1/2, hepatitis B, hepatitis C, syphilis, chlamydia, gonorrhea, and CMV.

• Semi-annual update of medical history, genetic history, and HIV risk assessment.

• Annual physical exam, including urinalysis, CBC, liver panel, and chemistry panel.

• Six months after the donor has provided his final semen sample, we perform exit testing for HIV-1/2, HTLV-1/2, hepatitis B, hepatitis C, and syphilis and CMV.
