Abstract
OBJECTIVE
Comparison of two transfer catheters in an IVF program.
DESIGN
Prospective, randomized clinical study.
SETTING
A private tertiary care center for ART.
PATIENT(S)
66 patients < 38 years of age undergoing IVF and/or ICSI.
INTERVENTION(S)
Patients were randomly assigned to undergo ET using the Tomcat catheter (n = 32) or the TDT catheter (n = 34).
MAIN OUTCOME MEASURE(S)
Primary outcome measures were implantation and pregnancy rates. Secondary outcome measures were contamination with blood and/or mucus on the tip of the catheter, cramping or patient discomfort, and time required to complete ET.
RESULT(S)
Use of the Tomcat catheter resulted in significantly higher implantation (25.2% vs. 8.4%) and clinical pregnancy rates (47% vs. 14.7%) compared with the TDT catheter. All secondary outcome measures were similar for both catheters.
CONCLUSION(S)
The choice of ET catheter may affect the success of IVF-ET cycles. Use of the Tomcat catheter compared with the TDT catheter seems to result in significantly better efficiency of the ET procedure and is more cost effective.
