The preimplantation genetic diagnosis (PGD) is a technique in which early human embryos, obtained in vitro for artificial fertilization techniques, are genetically screened for selection, through study of one or two blastomeres taken by biopsy. The embryos, that are healthy, are transferred to uterus. The PGD has been introduced in the early 1990s as an alternative to prenata1 diagnosis for couples at high risk of transmitting a genetic defect. It has been subsequently extended to other indications as the individualization of chromosomal abnormalities, the research of the aneuploidies, the "social selection of sex", the selection of the embryos according to the type of Human Leukocit Antigen (HLA) and the individualization of late-onset genetic diseases. But the reports concerning with the use of PGD in the world make clear that there are three critical points: the first deals with the diagnostic accuracy, with the presence of false positives and false negatives; the second, with the wide loss of embryos during the process; the third, with the outcomes of the PGD in terms of birth of healthy babies.
