The BBC reports: Time-lapse imaging which takes thousands of pictures of developing embryos can boost the success rate of IVF, according to British research.
The method, reported in Reproductive BioMedicine Online, can be used to select embryos at low risk of defects.
Scientists at the CARE fertility group say such informed selection can improve birth rates by 56%.
Other experts say the result is exciting, but the study of 69 couples is too small to be definitive.
The research followed the couples at the CARE fertility clinic in Manchester last year, when 88 embryos were imaged and implanted.
