New Embryo Screening Technique for Better IVF Outcomes
Fertility doctors are continually studying methods of embryo selection to improve pregnancy rates with in vitro fertilization (IVF). One Canadian fertility clinic now uses a new technology to select embryos most likely to develop into blastocysts based on their behavior in early developmental stages. The Early Embryo Viability Assessment Test, otherwise known as Eeva, is a software that reliably and consistently monitors subtle differences in embryo cell division. It helps fertility doctors to transfer only the embryos likely to graduate to blastocyst stage and become a viable pregnancy.
The Eeva Assessment Test process involves placing fresh embryos in a special test dish. A microscope then takes video images of the embryos while developing in an incubator. The video images are then analyzed and interpreted. The embryos with the most promising developmental patterns are then selected for transfer.
