Australian scientists make IVF discovery

The Telegraph has reported that a study of more than 50,000 births in Australia and New Zealand found the death rate of babies conceived using in-vitro fertilisation is significantly reduced when only one embryo is implanted.

The study found the difference was more pronounced in births involving fresh rather than frozen embryos. Births involving two fresh embryos had a 74 per cent higher risk of perinatal mortality than births following fresh single transfers.

The study leader, Elizabeth Sullivan, said the findings showed that Australia’s policy of promoting single embryo implants had helped to reduce infant mortality rates.   Countries such as the United States and the United Kingdom have rates of single embryo transfers of between 12 and 15 per cent, compared with 70 per cent in Australia.
