Results of the ECB method and the biopsy method were the same but were different from that of the remaining embryo. In this case, cell biopsy (TE) showed a clear chromosomal 7 aneuploidy but the remaining embryo (RE) had normal chromosomes while the embryo culture medium/blastocoel fluid (ECB) showed a half decrease at chromosome 7. Clearly, the result of cell biopsy did not represent that of the remaining embryo. It is likely that the aneuploidy only existed in the biopsied cells but not in the entire embryo. In this case, the culture medium/blastocoel fluid would be a better representation of the chromosomal dynamics of the entire embryo.
