RESUMEN

La aplicación de la tecnología genómica inició una nueva era en el campo de la medicina reproductiva, con gran potencial de desarrollo en los próximos años. En la actualidad, durante un ciclo de fecundación in vitro (FIV) es posible obtener material genético de un ovocito o de un embrión en desarrollo y evaluar así los 23 pares de cromosomas. Esto se conoce como tamizaje genético preimplantacional, que permite identificar aneuploidías (alteración en el número de cromosomas) en ovocitos o embriones en desarrollo. Recientemente, el tamizaje genético preimplantacional se propuso para identificar embriones euploides potencialmente viables y elevar las tasas de implantación y de nacidos vivos. Sin embargo, a quiénes deberá ofrecerse el tamizaje genético preimplantacional es un tema de gran debate.
