title: Introduction: nongenetic markers of oocyte and embryo competence.
abstract: The authors of this Views and Reviews have outlined the complexities of oocyte and embryo development and candidates for markers of embryo competence. Time-lapse monitoring of embryo development allows hierarchical selection of embryos for day 3 transfer. However, for normal-prognosis patients, extended embryo culture and comprehensive chromosome screening currently stand as the ultimate tools for the selection of embryos capable of a viable, normal delivery.
