Objective: To evaluate the place of ultrasound-directed transvaginal transmyometrial ET in a protocol using both the transcervical and transmyometrial routes in a step-wise fashion.
Design: A prospective descriptive clinical study.
Setting: A university-based assisted conception unit.
Patients: Thirteen patients who had difficult or impossible mock transcervical ET immediately before the real transfer.
Intervention: Ultrasound-directed transvaginal transmyometrial ET.
Main Outcome Measures: Pregnancy and clinical pregnancy.
Results: Four patients became pregnant, including three with clinical pregnancies.
Conclusions: In cases in which transcervical ET isd difficult or impossible, transvaginal transmyometrial ET is a viable option. The use of mock transcervical ET immediately before the real transfer would identify patients needing transmyometrial ET.

Background: Embryo transfer is a crucial step in IVF-embryo transfer cycles. Several studies have explored transmyometrial embryo transfer, but although this procedure has several favourable characteristics, its role in assisted reproduction has not yet been established. Junctional zone (JZ) contractions during embryo transfer are associated with a negative outcome and factors which increase JZ contractions should be avoided.
