How are donors screened?

Before donating, sperm donors begin by filling out an application that includes such information as their age, occupation, education, and ancestry.  After their initial application, donors provide a sperm sample for initial analysis, and then they provide a blood sample and an extensive medical history.  Finally, sperm donors take blood tests throughout the time of their donations for:

  • HIV
  • Human T-cell lymphotropic viruses
  • Syphilis
  • Chlamydia
  • Gonorrhea
  • Hepatitis B & C
  • Cytomegalovirus (CMV)
  • Karyotyping 46 XY
  • Transmissible spongiform encephalopathy or Creutzfeldt-Jakob disease

Sperm is frozen and stored for a minimum of 6 months before being released for use to ensure that the donor is healthy and disease-free. For a sperm bank with extensive testing, see the Seattle Sperm Bank:
