Frozen embryos are just as likely to result in a successful pregnancy as fresh ones, a new landmark study suggests.

Researchers discovered the technique, considered ‘controversial’, was slightly more effective in terms of live birth rates.

The new results, set to be published in The New England Journal of Medicine, were drawn from a trial of nearly 800 infertile women.

Frozen embryos resulted in pregnancies for 36 per cent of women – compared to 35 per cent in the fresh group, the ‘reassuring’ study found.

They were also more likely to result in children being born alive, with 34 per cent in the frozen group compared to 32 per cent in the fresh.

The ‘important’ findings dispute Government figures from 2010 that revealed frozen embryos were 10 per cent less likely to result in pregnancy.

The latest findings, led by Australian and Vietnamese researchers, offer more hope of making it the main option for IVF treatment in future.

Professor Ben Mol, co-author, based at the University of Adelaide, described the study as ‘important news for infertile women worldwide’.
