<qa>  What is the value of time lapse monitoring systems?Most recently, time-lapse incubators TLI have been introduced as a novel embryo culture system attempting to limit culture disturbances. These incubators have been integrated with digital imaging, allowing for a substantial limitation in embryo handling and environmental disturbances. They have also introduced new morphokinetic parameters to embryo assessment and to optimizing selection of embryos. Thus far, a limited number of studies have examined the clinical outcomes and value of time lapse monitoring systems versus the more ubiquitous incubators e.g. multichamber for reproductive outcomes. In particular, the isolated value of morphokinetics in embryo assessment and of this new stable culture environment in TLI are still in question.
