The Science Behind the Eeva Test

Landmark Research in the Field of IVF

The Eeva Test was developed based on landmark research conducted at Stanford University, and recognized by Time magazine as one of the top ten medical breakthroughs in 2010

Researchers at Stanford University discovered that precise patterns and timing of early embryo cell-division events could predict the embryo’s developmental outcome and reflect its underlying genetic health. This discovery was key to developing a non-invasive method to predict on Day 3 which embryos were most likely to develop to the critical blastocyst stage on Day 5.


The Eeva Test uses time-lapse video monitoring of each embryo during incubation. A special camera-equipped microscope placed inside the incubator captures video of each of the developing embryos. These time-lapse videos are analyzed by intelligent computer software that assesses the patterns and timing of each cell division and identifies those embryos with a high probability of further development.
