Abstract
Objective: To evaluate the use of maximal implantation potential (MIP) point in conjunction with a 3D/4D ultrasound in order to facilitate embryo transfers and potentially improve pregnancy rate.
Design: Retrospective, observational study.
Setting: IVF Center.
Patient(s): Between October 1, 2002, and August 27, 2004, 1,222 patients who underwent 3D/4D-ultrasound guided embryo transfers.
Intervention(s): Ultrasound-guided embryo transfer using a 3D/4D ultrasound machine and the MIP point.
Main outcome measure(s): Procedure feasibility with improved visibility.
Result(s): Embryo transfers were performed at the MIP point and the pregnancy rate was 36.66% (average patient age, 37.6 years). Physicians reported improved visualization and a greater accuracy in the placement of embryos within the uterine cavity.
Conclusion(s): The MIP point can be immediately identified and individualized for each patient. Embryo transfers at the MIP were associated with good implantation and pregnancy rates.
