For couples hoping for a baby, In Vitro Fertilization (IVF) is currently one of the popular methods of conceiving. But this method may not always result in successful pregnancies. Now researchers from Stanford University School of Medicine have devised a two part approach of embryo analysis that identifies the best developing embryo that might lead to a pregnancy.
The researchers said that it is a common occurrence for cells in an embryo to sometimes breakdown into fragments. During this process there is either loss or gain in genetic material in the embryo. This fragmentation occurs in very early stages of human development.
By analyzing each embryo for this particular trait, the study authors found that they could select the embryo that had the correct number of chromosomes, therefor increasing the chances of a successful pregnancy than the other embryos.
”It is amazing to me that 70 to 80 percent of all human embryos have the wrong number of chromosomes,” said Renee Reijo Pera, PhD, professor of obstetrics and gynecology. “But less than 1 percent of all mouse embryos are similarly affected. We’re trying to figure out what causes all these abnormalities.”
