Preimplantation genetic diagnosis can be used to establish a pregnancy with an embryo that is human leukocyte antigen (HLA)‐matched to a sibling having a hematological or immunological disease and needing a life‐saving bone marrow transplantation. The ethical aspects of this procedure have been discussed intensively. The procedure applies where no unrelated HLA‐matching donor is available or when transplantation from an HLA‐matching sibling is considered a better solution. It is only offered in a limited number of centers in Europe as this is a challenging procedure. Where both HLA matching and diagnosis of a dominant disease are necessary, only a small proportion of the embryos can be used, and the procedure is not always technically feasible. The clinical pregnancy rate per cycle started is much lower than following normal in vitro fertilization (IVF) due to a high cycle cancellation rate, but the success rate is only somewhat lower when measured per transfer.
