The test, called an endometrial receptivity analysis, takes a biopsy of the interior lining of the uterus and analyses the tissue for more than 200 genes to predict the best time to place the embryo in the uterus, according to the test's manufacturer, Igenomix

A study that compared live birthrates for first-time in vitro fertilization patients who underwent an expensive analysis that is supposed to predict the best time to place the embryo to patients who did not use the analysis found no difference in the chances of achieving an ongoing pregnancy.
