Early Embryo Viability Assessment Test allows analysis of early embryo development and aids in the selection of the best embryo for transfer. It is a novel technique developed specifically to increase chances of pregnancy in IVF, by helping embryo selection.
Computer-automated time-lapse analysis has been shown to improve embryo selection by providing quantitative and objective information to supplement traditional morphology.
To assess the quality of embryos visually during development is termed Embryo grading. Embryo grading is performed using a microscope to observe the embryo stage and quality at set times (usually once or twice a day) only. This minimises the disturbance due to exposure outside of the controlled environment of an incubator. The assessment is based on visual appearance of the embryos such as the number of cells, symmetry of cells and degree of cell fragments.
EEVA is a sophisticated set-up which contains a microscope along with a camera that can easily fit inside an incubator. The camera records images taken at set times. This helps analyse embryo development during the critical first few days, without removing the embryos from from controlled environment. It takes images at certain set times of the embryos during the critical first days of development. This data helps evaluate which embryo(s) have the best potential for further development and will result in successful pregnancy.
There are many factors that contribute to a successful live birth, but identifying the best embryos in the first few days is one of the most critical.
The benefits of EEVA include:
