La inyección intracitoplasmática del espermatozoide (ICSI) ha permitido resolver problemas masculinos severos con excelentes resultados. Sin embargo, la difusión de su técnica llevó a la aplicación en casos donde no existe una indicación clara, desplazando muchas veces a la fertilización in vitro (FIV) sin suficientes argumentos. Esta revisión pretende, partiendo de conceptos fisiológicos de fecundación, llamar la atención sobre los eventos involucrados en el ICSI que transgreden dicha fisiología y constituyen grandes enigmas en cuanto a sus implicaciones en el desarrollo futuro. Las diversas observaciones descritas por los grupos de investigación básica dedicados a estos análisis, si bien no establecen un efecto indeseable inherente a la técnica, dejan abierta la investigación y permiten concluir que el ICSI es una técnica con claras indicaciones que no debe utilizarse indiscriminadamente.Biografía del autor/a
