New Delhi, Aug 25
Genetic testing of IVF-created embryos could help more women over 35 have a baby in less time, according to a study on Monday.
Researchers from King’s College London, UK, led the first randomised controlled trial worldwide to focus exclusively on women aged 35-42 -- a group at higher risk of producing embryos with chromosomal abnormalities.
The trial looked at the use of Preimplantation genetic testing for aneuploidy (PGT-A) to check embryos for chromosomal abnormalities before transfer.
Older women are more likely to produce embryos with the wrong number of chromosomes, which can lead to difficulties in conceiving and increase the risk of miscarriage.
The results, published in the Journal of Clinical Medicine, showed that the PGT-A test showed a higher cumulative live birth rate after up to three embryo transfers, with 72 per cent in the PGT-A group versus 52 per cent in the control group.
