Melbourne: With the launch of a new technique, scientists are set to revolutionise IVF treatment in Australia and offer fresh hope to childless couples.In a month`s time, patients will be able to access technology that screens every chromosome in their embryos for defects that could prevent pregnancy or result in miscarriage.Only eight to 10 chromosomes can currently be screened for genetic errors, which sees a high number of healthy-looking embryos turn out to be defective, wasting patients` time and causing significant distress.
The patients most likely to benefit are women aged over 38, those with hereditary chromosomal conditions, those who have a record of unsuccessful IVF cycles and women who are prone to miscarriage.The new technique, known as microarray comparative genomic hybridisation, compares DNA from the embryo with normal DNA to show up errors and turns around results in just 36 hours.The European Society of Human Reproduction announced last week that four women had given birth to healthy babies after having their eggs genetically screened using the same technology.But Wilton said it was far more comprehensive to test embryos."We firmly believe that it is much more valuable to screen the embryo because, although there are chromosome errors in eggs, there are many more chromosome errors that occur in the first few days of the embryo`s development," added Wilton.
