UK-based researchers discovered a new screening technique to test embryos for chromosomal abnormalities, the most common type of early pregnancy loss.
The test, which enables doctors to detect abnormalities in the embryos before they are reimplanted into the womb, is expected to double or even triple current IVF success rates. Chromosomal abnormalities account for 70% of early pregnancy losses.
The new discovery brings tremendous hope for those struggling to overcome infertility.
The new technique is being spearheaded by CARE Fertility in Manchester, England, where trials are currently underway.
The test allows doctors to analyze the chromosomes that make the babies on the fifth day of IVF, before they are reimplanted.
"Before we would look down a microscope and see five, six, maybe 10 embryos knowing that half are chromosomally abnormal but there's no way of testing it. Now we have an objective test that is related to the health of the pregnancy," CARE director Simon Fishel stated.
"In other words, each embryo is much more efficient at implanting and maintaining that pregnancy."
Success by IVF currently depends on a woman's age. "So at the moment a woman of 40 who had a 10% chance of pregnancy will probably be as high as 30% so that's trebling that pregnancy rate."
Three women in Britain are due to give birth using the new screening technique late next month.
Dr. Fishel is tremendously confident about the positive effects of the new testing technique and the further results of pregnancy in the upcoming six to 12 months.
