A new screening technique for embryos is likely to boost success of current IVF techniques quite considerably. This is a test that can detect chromosomal abnormalities in embryos before they are reimplanted into the uterus so that the chances of pregnancy loss is significantly lowered.
Chromosomal abnormalities are one of the chief causes of miscarriage early on in a pregnancy and so this test is expected to double or even triple the rate of success of IVF procedures.
This is a technique being pioneered by fertility specialists at CARE Fertility in Manchester, England. Three women in their late 30s who have used the technique will be giving birth in December this year.
This screening for embryos allows testing of the embryos without causing any damage; so it can be known which the viable embryos are and which are likely to end up in a miscarriage, prior to actually implanting them in the uterus.
Until now, researchers were able to see up to 10 embryos with the help of a microscope, know that half would be abnormal but had no way of knowing which ones. Now, however researchers are hopeful that this technique will allow for significant improvements in the methods of IVF currently in use and will also help more women achieve a successful, sustainable pregnancy.
