Development of a Screening Tool for Difficult Embryo Transfers

The screening questionnaire will be filled by the Physician doing the OPU. The screening questionnaire will be informed by the participant's history. Cervix will be visualized during routine vaginal cleansing for OPU, and its appearance (size, and deviation) will be recorded in the screening questionnaire after the OPU procedure. Finally, a screenshot of the ultrasound used for OPU, showing the cervix and cervical canal in the sagittal plane will be taken during routine procedure and saved in electronic chart.

When the participants comes back for ET during her routine treatment, ET will be done in exactly the same way in routine treatment. Participant will not undergo any additional manipulation, intervention, nor the procedure will take longer. The Embryologist assisting the procedure will record the duration of the procedure, from the moment the Physician takes the outer ET catheter to his/her hand until he/she passes the cervix and calls for the inner catheter loaded with the embryo. Up on completion of the ET procedure as routine practice, the Physician will fill a questionnaire about the procedure.
