"Cells move and change in very weird ways during the five days the embryo is in an incubator and it's completely beyond any human to work out what all that means," Dr Peter Illingworth, medical director at IVF Australia, who is leading the trial, said. "What the AI tool can do is analyse all the embryos. The embryo with the highest score can then be selected for transfer by the embryologist with the aim of accelerating the chance to a successful pregnancy." Dr Illingworth said the purpose of the study was to determine whether the technology can shorten the time it takes a woman to fall pregnant, ultimately saving aspiring parents thousands of dollars in fertility treatment. "It's a very promising tool, but does it really help women, that's the question," he said.
