HLA-matched embryos selected for siblings requiring haematopoietic stem cell transplantation: a psychological...

Allogeneic haematopoietic stem cell transplantation (HSCT) is a treatment for a number of acquired and congenital diseases. An important factor in the outcome of the treatment is the degree of human leukocyte antigen (HLA) compatibility between patient and donor. HLA identical siblings therefore provide the best chance for the recipient. Preimplantation genetic diagnosis (PGD) can be used to select HLA identical embryos if there is no HLA compatible sibling in the family. The Centre for Reproductive Medicine considered it morally justified to give medical assistance to couples in need of an HLA matched sibling. Two considerations played an important role in this respect: (i) the use as a donor should not be the only parents' motive for having the child and (ii) IVF and HLA typing on the embryos would be less of a burden for the parents than other alternatives. Since the first request in 2000, 12 couples have been referred for psychological counselling. The motivation of four couples will be discussed in depth. The validity of the arguments will be checked against the experience of the actual cases. The consequences of the treatment on the welfare of the future donor child will be discussed.
