Does prospective embryo selection using the results from the Eava Test (Early Embryo Viability Assessment) in combination with standard morphology increase the pregnancy rate of IVF and ICSI patients compared to embryo selection based on morphology only? Embryo selection using the Eeva Test plus standard morphology on Day 3 results in comparable pregnancy rates as conventional morphological embryo selection. Time-lapse monitoring of embryo development may represent a superior way to culture and select embryos in vitro. The Eeva Test records the development of each embryo with a cell-tracking system and predicts the likelihood (High, Medium or Low) that an embryo will form a blastocyst based on an automated analysis of early cell division timings. This trial was designed as a prospective, observational, two-center pilot study with a propensity matched control group. The analysis involved 280 of 302 enrolled patients who were included in the Eeva Test group in 2013 and 560 control patients who were treated in the years 2011-2013. The majority of transfers (98%) were single embryo transfers. Two academic hospitals (VUmc Amsterdam and UZ Gent) enrolled patients
