In cases referred for IVF (or IUI) where there is suggestion from the history or examination of cervical stenosis (as in Case Histories 1 and 2), a “mock” ET (also called “dummy” or “trial” ET) should be performed [10]. This is when an empty ET catheter is passed through the cervix, thus mimicking what would happen at the actual ET. This should be carried out as an interval procedure before the start of the IVF process, so as to identify women who have cervical stenosis and allow time to plan remedial action. Because most cases of cervical stenosis have no indicative history (as in Case History 3), some IVF units perform mock ET as a routine in all cases [10].
