Screening test 'ups chances of pregnancy for women on IVF'

London, October 18 (ANI): A genetic-screening test is likely to increase chances of pregnancy for women using in-vitro fertilisation (IVF), according to a study.

Dagan Wells, a Senior Fellow in Reproductive Genetics at Oxford University, came up with the technique called comparative genomic hybridisation (CGH) to examine chromosomes in the developing embryo.

The first trial of the 2,000-pound test discovered that that 66 per cent of women became pregnant if their embryos were checked for abnormalities before being implanted in the womb, more than double the proportion (28 per cent) of women who fell pregnant without the test.

"We were taken aback by the impact it had on the success rates," Times Online quoted Dr Wells as saying.

"I think it's at the point now that we can say with great confidence that we are seeing a positive effect of this," Dr Wells added. (ANI)
