Early Embryo Viability Assessment (Eeva)
Definition - What does Early Embryo Viability Assessment (Eeva) mean?
Early embryo viability assessment (EEVA) is a relatively recent technology (as of 2016) that allows laboratories conducting in vitro fertilization treatments (IVF) to analyze the embryos and select the most promising specimen for transfer. This non-invasive testing is believed to increase the chances of a successful IVF procedure. The analysis provided by the EEVA program allows for selection of the demonstrably strongest embryo with statistically high changes of normal development.
FertilitySmarts explains Early Embryo Viability Assessment (Eeva)
EEVA is completed through high-level monitoring technology that utilizes time-lapse video and analysis of the development of the embryo following fertilization. The program uses sophisticated software and a scientific equation to predict which embryo is likely to progress to the stage of blastocyst, the next stage of embryonic development critical to successful pregnancies.This information is gathered through precise tracking of the patterns and timing of the earliest divisions of the cells.
Extensive research has yet to be conducted on the long term outcomes of EEVA procedures. However, the test signifies the first non-invasive procedure that allows for predicting an embryo's developmental potential and providing insight to it's genetic foundation.
