The Glasgow Centre For Reproductive Medicine, Scotland's largest independent fertility clinic, became the second in Europe to offer the test which can tell in 48 hours whether an embryo is likely to survive.

Now they say they expect to deliver the first baby using Early Embryo Viability Assessment (EEVA) which was introduced in December.

About one in six couples have difficulty conceiving and approximately 3.5% of all first births are presently as a result of IVF treatment in Scotland.
