The study will evaluate embryos from four IVF clinics in the San Francisco Bay Area.

The goal of this study is to demonstrate that the Eeva System may be used to identify embryos at cleavage stage that are most likely to form blastocysts.

The predictions will be compared to the actual blastocyst outcome as observed at the clinical sites.

The Eeva System consists of an imaging component within the IVF incubator, a proprietary culture dish, image analysis software that measures specific parameters during embryonic development and a prediction algorithm.

The system is designed to be used by embryologists as an adjunct to traditional morphology to help identify, by day 3 of incubation, where embryos continue to develop into blastocysts, a critical time point in human development that happens on day 5.
