Doctors typically use the woman's age as the main factor in predicting the likely outcome of IVF, but this can be unreliable. To improve on this method, Banerjee's team used clinical and embryo data from over 1600 IVF patients to identify the most influential factors determining whether a live birth will be achieved the second time around.
"While age is a major driving force towards decreased fertility, it does not have the highest importance once you have the embryo data," says Mylene Yao, who co-authored the paper. The team found the most influential factors included the number of cells that developed into early stage embryos, the thickness of the womb lining, and body mass index. When these factors were used together, the model was markedly better at predicting likely success of subsequent treatments than age-based predictions.
IVF is expensive and also carries physical and emotional costs, so many people struggle with the decision over a second attempt. "Understanding their probability of having a live birth, based on their very own clinical data, may serve to support that decision," says Yao
