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
