ET under transabdominal US guidance (UGET)
When UGET was used, a second physician performed trans-abdominal US, and the embryos were discharged when the tip of the catheter was visualized approximately at 1,5 cm from the fundal endometrial surface
ET after transvaginal US uterine measurement (mTVET)
When mTVET was scheduled, the physician performed a transvaginal US scan just before ET, measured the length of the cervix and of the uterine cavity, and calculated the distance between the internal uterine os and the fundal endometrial surface. Then, ET was performed inserting the inner cannula in order to discharge embryos at a point obtained subtracting 1.5 cm from the total length of the cavity.
