Resumen

En la década de los noventa el desarrollo de la técnica para cultivar y transferir blastocistos luego de una fertilización in vitro ha reportado beneficios en ciertos aspectos cruciales de esta práctica. El mayor control sobre la incidencia de embarazos múltiples es una de sus principales bondades. El proceso de autoselección al que se someten los embriones ha permitido que se transfieran embriones mas viables y con una mayor capacidad de implantarse en el endometrio. También ha contribuido al desarrollo de una nueva ola en la evaluación y el diagnóstico preimplantación del embrión. Detallados análisis de los fenómenos metabólicos cambiantes en el embrión temprano han permitido la aparición de nuevos medios de cultivo que soportan el crecimiento embrionario in vitro hasta su estado de blastocisto. Estos medios están reemplazando al cocultivo como herramienta preferida para cultivar blastocistos. Sin embargo aun existen interrogantes sobre el mecanismo de acción de los cocultivos y sobre la forma en que algunos de sus efectos benéficos como la producción de factores embriotroficos específicos, puedan ser incorporados a los nuevos medios.
