Abstract
Time-lapse systems have quickly become a common feature of in vitro fertilization
laboratories all over the world. Since being introduced over a decade ago, the alleged
benefits of time-lapse technology have continued to grow, from undisturbed culture
conditions and round the clock, noninvasive observations to more recent computer-assisted
selection of embryos through the development of algorithms. Despite the global uptake
of time-lapse technology, its real impact on clinical outcomes is still controversial.
This review aims to explore the different features offered by time-lapse technology,
discussing incubation, algorithms, artificial intelligence and the regulation of nonessential
treatment interventions, while assessing evidence on whether any benefit is offered
over conventional technology.
