  • New embryo test to improve IVF success rate

    Researchers at Oxford University have developed a test that may help to improve IVF success rates by checking the health of embryos.

    The team, led by Dr Dagan Wells, has apparently developed a test which checks embryos during IVF for abnormal numbers of chromosomes. They tested a few cells taken from early human embryos, each of which should contain 23 pairs of chromosomes. With more or less than this, embryos can fail to develop normally.
