Using computer-automated, time‐lapse photography during IVF treatment may improve embryo selection, potentially improving the chances of conception, according to new research from the Perelman School of Medicine at the University of Pennsylvania
Scientists used the Early Embryo Viability Assessment (Eeva) imaging device to record and evaluate embryos transferred into the uterine cavity of 177 patients.
The images - taken at five minute intervals - were fed into a software program that assesses the developmental potential. The embryos were rated either as ‘high’, ‘medium’, or ‘low’ for their capacity to reach the blastocyst stage by the fifth or sixth day of culture.
According to the results, patients with a least one ‘high’ rated embryo had a 54 per cent viable pregnancy rate, compared to 34 per cent for those with a ‘low’ rated foetus.
Dr Matthew VerMilyea, lead author of study and director of Assisted Reproductive Technologies and Andrology Laboratories at Penn, said: "Our findings provide promising news for couples using or considering in-vitro fertilization because it shows that this technology offers the prospect of selecting embryos that have a greater likelihood of resulting in a pregnancy.”
He added that as the participants were all from different fertility clinics, each with distinctive protocols and patient populations, the results suggest the technology could be generalisable.
