Artificial intelligence beats scientists in choosing embryos for IVF success

Scientists are using artificial intelligence (AI) to help predict which embryos will result in IVF success.

In a new study, AI was found to be more accurate than embryologists at pinpointing which embryos had the potential to result in the birth of a healthy baby.

Experts from Sao Paulo State University in Brazil have teamed up with Boston Place Clinic in London to develop the technology in collaboration with Dr Cristina Hickman, scientific adviser to the British Fertility Society.

They believe the inexpensive technique has the potential to transform care for patients and help women achieve pregnancy sooner.

AI is able to recognise and quantify 24 image characteristics of embryos that are invisible to the human eye.

These include the size of the embryo, texture of the image and biological characteristics such as the number and homogeneity of cells.

During the study, which used cattle embryos, 48 images were evaluated three times each by embryologists and by the AI system.

Stuart Lavery, director of the Boston Place Clinic, said the technology would not replace examining chromosomes in detail, which is thought to be a key factor in determining which embryos are “normal” or “abnormal”.

He said: “Looking at chromosomes does work, but it is expensive and it is invasive to the embryo.

“What we are looking for here is something that can be universal.

“As we get data about which embryos produce a baby, that data will be fed back into the computer and the computer will learn.”

He said work was under way to look back at images from parents who had genetic screening and became pregnant and that applying AI to those images will help the computer learn.

Lavery added: “Although further work is needed to optimise the technique, we hope that a system will be available shortly for use in a clinical setting.”
