简要总结
In view of insufficient evidence to routinely use Preimplantation Genetic Screening (PGS) to improve success rates after IVF, we test the hypothesis that patients with advanced maternal age (AMA) have a higher implantation rate (IR) after embryo transfer (ET) of chromosomally normal embryos following PGS compared to patients who had an ET without PGS.
In a randomized controlled trial (RCT) in patients with AMA (≥ 35 years), the clinical IR per embryo transferred will be compared after ET on day 5 or 6 between the PGS group (embryo biopsy and analysis of chromosomes 13, 16, 18, 21, 22, X and Y) and the control group without PGS.
