Genetic testing of IVF-created embryos could help more women over 35 have a baby in less time, according to a study on Monday.

Researchers from King’s College London, UK, led the first randomised controlled trial worldwide to focus exclusively on women aged 35-42 -- a group at higher risk of producing embryos with chromosomal abnormalities.

The trial looked at the use of Preimplantation genetic testing for aneuploidy (PGT-A) to check embryos for chromosomal abnormalities before transfer.
