PG - 2849-58 AB - BACKGROUND: It is generally accepted that the age-related increased aneuploidy rate is correlated with reduced implantation and a higher abortion rate. Therefore, advanced maternal age (AMA) couples are a good target group to assess the possible benefit of preimplantation genetic diagnosis for aneuploidy screening (PGD-AS) on the outcome after assisted reproductive technology (ART). METHODS: A prospective randomized controlled clinical trial (RCT) was carried out comparing the outcome after blastocyst transfer combined with PGD-AS using fluorescence in situ hybridization (FISH) for the chromosomes X, Y, 13, 16, 18, 21 and 22 in AMA couples (aged > or =37 years) with a control group without PGD-AS. From the 400 (200 for PGD-AS and 200 controls) couples that were allocated to the trial, an oocyte pick-up was performed effectively in 289 cycles (148 PGD-AS cycles and 141 control cycles). RESULTS: Positive serum HCG rates per transfer and per cycle were the same for PGD-AS and controls: 35.8% (19.6%) [%/per embryo transfer (per cycle)] and 32.2% (27.7%), respectively (NS). Significantly fewer embryos were transferred in the PGD-AS group than in the control group (P<0.001). The implantation rate (with fetal heart beat) was 17.1% in the PGD-AS group versus 11.5% in the control group (not significant; P=0.09). We observed a normal diploid status in 36.8% of the embryos. CONCLUSIONS: This RCT provides no arguments in favour of PGD-AS for improving clinical outcome per initiated cycle in patients with AMA when there are no restrictions in the number of embryos to be transferred.
