IF THE BLOOD TYPE OF A SEMEN DONOR IS IMPORTANT TO YOU....

Many patients feel that the blood type of the donor is crucial when choosing a donor. By selecting a donor whose blood type matches the husband's/partner's blood type, patients may feel more secure about issues related to confidentiality.

The donor's blood type may be medically important to consider if the mother is Rh negative (Rh-). These women may develop antibodies to a fetus that is Rh positive.

It is important to remember that children do not always inherit the same exact blood type as their biological parents. For example, a couple with blood types of A and B could have an offspring with any of the four blood types: A, B, O, or AB.
