Zusammenfassung: | The emergence of the array comparative genomic hybridization technique (aCGH) is considered an advance in preimplantation genetic testing. Analysis of the recently published pilot study using polar body aCGH indicates that the test accuracy compares favourably with the fluorescence in situ hybridization technique although a substantial number of euploid zygotes are still likely to be excluded incorrectly. A sound argument against selection in principle has recently been published, based on accumulating evidence that potentially all embryos can now be cryopreserved and transferred in subsequent frozen replacement cycles without impairing pregnancy rates. We suggest that vitrification and serial transfer without testing are likely to give patients the best chance for a successful pregnancy, and avoid the use of an expensive technology. |
