How do I know that I have been matched with the most compatible donor?

Donation in Spain is an anonymous and altruistic process. Under this concept, the recipient (in this case of oocytes) will not be able to know anything about the donor except her age and blood group. However, for donor selection and donor assignment, a phenotypic match/similarity is made on the basis of the physical characteristics provided by the recipient and confirmed in consultation with the attending physician.

In the same way, assisted reproduction centers use facial recognition programs that perform a phenotypic matching between the recipient and the assigned donor. This matching is performed in the laboratory by those in charge of the oocyte donation department.

Therefore, the phenotypic matching will be done according to the donor's phenotype, being mandatory that the blood group is the same or compatible with that of the parents. An attempt is made to adapt as much as possible to the height, eye color, hair color and skin color.

Genetic matching (Genetic Compatibility Test - Recessive Disease Carrier Test) is also advised to all couples in order to make a proper matching prior to donor assignment. This is a study performed on all donors as part of the studies prior to the start of treatment.
