A New Hysteroscopic Tubal Embryo Transfer Catheter : Development and Clinical Application

Objective: Development and clinical application of a new hysteroscopic tubal embryo transfer catheter. Method: Catheterization was performed in 60 patients at hysteroscopic insemination into tube, using 3 French catheters, in which the distal 3,4, and 5 cm tapered to 2 French. Hysteroscopic tubal embryo transfer and conventional IVE-ET were performed in 30 patients with normal tubes, who failed to achieve pregnancy after 2 IVF-ET trials. Result: The success rate of complete insertion with the catheter tapering at the distal 3 cm was significantly higher than that at the distal 5 cm. Since we obtained the highest success rate of insertion with the catheter tapering at the distal 3 cm, we selected this catheter for the h-TEST. The rate of pregnancy in h-TEST was significantly higher than that in conventional ET. Conclusion: The h-TEST using our catheter was useful for establishing pregnancy in assisted reproduction.
