Popis: Objective To apply preimplantation genetic diagnosis (PGD) for the treatment of patients with a history of failed IVF-ET or habitual aborters. Design Prospective clinical study. Setting Tertiary center for assisted reproduction. Patient(s) Ninety-four couples with failed IVF-ET after >2 IVF cycles and 64 couples with >2 spontaneous abortions. Intervention(s) Patients were prepared for oocyte retrieval using standard controlled ovarian hyperstimulation protocols after standard laboratory techniques. Blastomeres from 6- to 8-cell embryos were analysed using fluorescence in situ hybridization with commercial chromosomal probes, and normoploid embryos were transferred on day 3 after fertilization. Main outcome measure(s) Pregnancy and implantation rates and live births. Result(s) Both 3- and 5-probe PGD resulted in a significantly higher outcome than controls for failed IVF-ET. Five-probe PGD appeared to be more suitable for habitual aborters. Conclusion(s) This pilot study suggests that 3-probe PGD is a valid option for failed IVF-ET patients. The use of five or more probes is indicated for habitual aborters.
