Before selecting a sperm donor, predict your blood type and Rh compatibility

When selecting a sperm donor, your blood type compatibility is important to consider.

Please consult your physician about any ABO or Rh compatibility issues in a future pregnancy. Women that are Rh- who select a Rh+ donor may require treatment with Rhogam during pregnancy. It’s important to discuss this with your physician before you get started.
