As explained by the American Red Cross, “in addition the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (-), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-).” Now, let’s review how blood types work and how the offspring's blood type is determined.Įvery person has a specific blood type.

Thank you for existing, because of you, we have her!” In fact, we are thinking about doing it again in the future, if possible. Ultimately, we respect that intended parents will make the decision that is right for their family. We understand that this is a personal decision that may be influenced by religious and cultural factors among others. This concern is due to the possibility of the child inheriting a specific blood type from the egg donor that is not a possible combination of the intended mother and intended fathers’ blood types. The egg donor’s blood type is important to intended parents who are not planning on telling their child that they were conceived with the help of an egg donor. Why does blood type matter to some intended parents? RhoGAM prevents the Rh-negative mother from making antibodies during her pregnancy. However, in the less common situations where the recipient mother’s blood type is Rh negative and the embryo’s blood type is Rh positive, the obstetrician will administer a RhoGAM shot to the recipient mother. Similar to donor egg blood type, the blood type of the donor embryo does not affect the outcome of the cycle. “The donor blood type does not impact the outcome of the IVF cycle or the health of the child.” What about when using donor embryos? One less decision for you to worry about! The donor blood type does not impact the outcome of the IVF cycle or the health of the child. Does the egg donor’s blood type matter? Interestingly, the answer is no. Then you realize there are many other aspects to consider, such as the donor’s blood type, and wonder if you need to factor that into your decision-making.
