'IVF time-lapse study needs more evidence'

A group of British researchers in Manchester have come up with a technique which they believe could significantly improve the success rate for couples undergoing IVF treatment to have a baby.

It involves taking thousands of time-lapse photographs of the earliest stages of the developing embryos in their incubator to get a clearer idea of which ones are the best to implant in the mother's womb.

Dr Sue Avery, from the British Fertility Society, warned that much bigger and longer studies will have to be made.
