When selecting a sperm donor, his blood type along with the blood type of the mother can be used to predict the possible blood types of their offspring. 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.
