For most intended parents, blood type is not a critical factor when they choose their sperm donor. 

While some believe that a matching blood type is necessary for a healthy pregnancy or that it impacts the child’s well-being, this is generally not the case.

If blood type is important to you, you can easily filter donors in our donor overview using the filter Donor Blood Type.

When blood type is NOT relevant

• No impact on fertility or pregnancy success
  Blood type does not affect sperm quality or conception chances.
• Not a genetic requirement
  The baby can have a different blood type than the parents without health concerns.
• Most parents don’t need to match blood type
  Unless a medical reason applies, blood type is usually not a selection factor – just as it isn't for natural conception.

When blood type MAY matter

• Rhesus (Rh) factor compatibility
  If the intended mother is Rh-negative and the donor is Rh-positive, the baby may be Rh-positive, which could lead to Rh incompatibility.
  Solution: Rh incompatibility is manageable with a simple Rh immunoglobulin (RhoGAM) shot during pregnancy.
• Personal preference
  Some parents may want a blood type match for personal reasons or future medical needs (e.g., organ donation compatibility).
• Cultural or family expectations
  Some families want their child to have a blood type that aligns with family members for cultural reasons or to align with family tradition.

If you're unsure whether blood type should play a role in your selection process for medical reasons, talk to your treating clinic for specific guidance.
