| Table 2. Embryo transfer tips |
| • Ultrasound guidance with optimal full bladder |
| • Minimize waiting time for the procedure |
| • Mock transfer, pre-cycled and just before ET |
| • Routine removal of cervical mucus with a moist gauze and 10 cc syringe with saline medium |
| • Use echogenic catheters |
| • Minimize time intervals to avoid the exposure of the embryos to ambient conditions |
| • Gentle manipulation. Advance the catheter as a unit to the inner cervical os. From there on, |
| advance only with the inner catheter. |
| • In difficult cases, try with wired inner catheter, stylet or obturators. Avoid to use a tenaculum! |
| • Distance from fundus should be 1,5 cm. Do not clinical touch! |
| • Minimum ejection speed |
| • Rotate the catheter 180° |
| • Pause to allows the embryos to settle away from the catheter tip |
| • Withdraw transfer catheter slowly |
| • Check catheter for retained embryos |
| • Retransfer immediately if it is needed |
| • Bed rest for 20 minutes |
