The positions of the air bubble and the tip of catheter will be measured by transabdominal utrasonography among patients who have undergone high-quality frozen blastocyst transfer. The aim of this study is to compare pregnancy rates according to air bubble's final location in endometrial cavity. It is expected that the ET technique will be improved and live birth rates will increase by determining the optimal position of the embryo in the endometrial cavity during ET in patients who have achieved pregnancy.
