Impacto del diagnóstico genético preimplantacional en embriones humanos

Abstract

Chromosome abnormalities are extremely common in human oocytes and embryos and are associated with a variety of negative outcomes for both natural cycles and those using assisted reproduction techniques. Aneuploidies embryos may fail to implant in the uterus, miscarry, or lead to children with serious medical problems (e.g., Down syndrome). Preimplantation genetic diagnosis (PGD) is a technique that allows the detection of aneuploidy in embryos and seeks to improve the clinical outcomes od assisted reproduction treatments, by ensuring that the embryos chosen for the transfer are chromosomally normal.
