New technology improves likelihood of finding better embryos

While harvesting embryos for implantation, it is important but always challenging to find the healthiest ones, the ones most likely to make it full term and produce a healthy baby. A new non-invasive technology has been created which allows precise recognition of the healthiest embryos at an even earlier developmental stage than had been available before.

Eeva should reduce risks

A research team from has developed the Early Embryo Viability Assessment (Eeva). It may result in more favorable outcomes and reduce the recommendation to move more than one embryo into the uterus. Multiple births would drop reducing one of the risk factors for women using IVF.

And help identify healthiest embryos

Currently embryos are assessed after developing five or six days in an artificial environment. The ones that thrive are considered the healthiest and most workable. These are implanted in the woman’s womb. The Eeva test takes pictures of the embryo every five minutes so it can monitor every cell division. Any abnormalities can be identified with a software program and be eliminated from consideration.

Identifies better embryos at an earlier stage

“This non-invasive test represents a major step forward in our ability to assess the viability of embryos. It means we can identify which embryos are developing correctly at an earlier stage. With further development and testing, this technique has the potential to help us allow more women to have single embryo transfer, the most effective method of decreasing the multiple pregnancy rate,” according to Dr. Joe Conaghan, Laboratory Director at the Pacific Fertility Center.

Should revolutionize IVF

“New time-lapse imaging techniques are set to revolutionize the field of embryology. They allow us to study embryo development non-invasively, in detail and more quickly compared to earlier methods. This study is a great start as it confirms that the Eeva system is able to predict the viability of embryos with a high degree of reliability,” concluded embryologist Hannah Marsden, Hewitt Fertility Centre, Liverpool.
