These embryos were examined by transvaginal ultrasonography and a comparison of their echogenicity was made with respect to those of the placenta and the myometrium. Grade II embryos were less echogenic than the placenta or had similar echogenicity with the myometrium, whereas grade I embryos shared the same echogenicity as the placenta. In contrast, grade III embryos were less echogenic than the myometrium.<\/jats:p><\/jats:sec>Results:<\/jats:title>Most of the embryos with cardiac activity were detected to have grade II echogenicity (78\/130, 60.0%), whereas the remaining embryos had grade I echogenicity (52\/130, 40.0%).
