The embryo transfer is a quick and simple procedure with no discomfort to the patient, but it is also one of the most important steps to ensure the expected outcome after all the hard work done (1).
Embryo transfer is routinely performed through the transcervical route. The quality and versatility of the ET catheters are essential to ensure a great user experience as Gynaecologists may encounter different patient conditions such as the presence of cervical mucus, acute uterine flexion, difficulty to pass through the internal os, or different lengths of the cervical canal and uterus.
Evaluation of the uterine cavity prior to embryo transfer allows to determine the length and angle of the cervical canal and the difficulty to access the uterine cavity, in order to choose the right ET catheter.
