Three-dimensional ultrasound in embryo transfer.
OBJECTIVE
To examine the feasibility of using three-dimensional (3D) ultrasound (US) guidance in routine embryo transfer (ET) procedures.


METHODS
Seventy-five ETs were performed using a 3D US scanner to locate the catheter tip in the uterine cavity.


CONCLUSIONS
Three-dimensional ultrasound could show the exact position of the tip of the catheter in the uterine cavity quickly enough in most cases. It should be used in ET for seeking an optimal transfer area in the uterine cavity to assist in achieving high success rates and less complications.
