New DNA test for embryos could boost IVF success rates

Data from several clinics in the US suggests that test boosts pregnancy rates by 10 percentage points, although it has not yet been approved for use in the UK

A test that checks for abnormal amounts of DNA in IVF embryos has raised pregnancy rates at US fertility clinics that have started to offer the procedure.

Scientists in Oxford who helped develop the test claim it can boost the chances of an IVF pregnancy by 10 percentage points, leading to success rates of about 75% in 35-year-old women.
