Screening Test ‘Doubles the Chance of Pregnancy for Women on IVF’
A genetic-screening test could more than double the chances of pregnancy for women who undergo fertility treatment, a study suggests.
The first trial of its kind has found that two out of three women having in-vitro fertilisation (IVF) became pregnant if their embryos were checked for abnormalities before being implanted in the womb, compared with less than a third where the test was not used.
The technique, known as comparative genomic hybridisation (CGH), checks chromosomes in the developing embryo. Only those embryos with the best chance of becoming a healthy baby are used in fertility treatment. The £2,000 test is available in only a handful of private clinics in Britain. Researchers hope that it will become standard practice to help both NHS and paying patients to start a family.
Dagan Wells, a Senior Fellow in Reproductive Genetics at Oxford University who developed CGH, said that babies had now been born among a group of 115 American women whose embryos had been screened.Read more.
