Preimplantation Genetic Diagnosis: Better IVF Results?
August 11, 2017
(Medscape) – The need to transfer fewer embryos while maintaining or increasing PRs prompted research of various embryo evaluation methods. Most embryos created in vitro are aneuploid and, therefore, do not or only rarely implant. Preimplantation assessment of chromosome content could enable the provider to transfer euploid embryos only. Results of screening with preimplantation genetic diagnosis for aneuploidy (PGD-A) have been mixed. Newer technologies have been shown to improve outcomes in young patients with a good prognosis. Good data on patients with a less favorable prognosis are unavailable, however.
