Embryo transfer technic – role of transfer catheter

Bapna Neelam, Swarankar Mohanlal, Kotia Namita, Soni RR

OBJECTIVE(S) :To analyze the performance of four different embryo transfer catheters viz. Wallace, Frydman, Labotect
and TDT in an IVF-ET Program.
METHOD(S) : The embryo transfer cycles were grouped into four according to the catheter used and the pregnancy rates
were compared in each group. Woman’s age, diagnosis, ovulation induction method and number of embryos transfered
were similar in all the four groups. The ease or difficulty in transfer was also noted and pregnancy rates compared.
RESULTS : The pregnancy rates were better (P<0.001) with soft catheters (Labotect 39.4%, Wallace 41.4%) as compared
to stiff ones (Frydman 24.2%, TDT 31.4%) but when the number of embryos transferred in each group was taken into
account and relationship between type of catheter and success rate was analyzed keeping the number of embryos fixed
in each group, there was no statistically significant difference in pregnancy rates between the four groups. The ease or
difficulty in transfer does not appears to influence the implantation rate.
CONCLUSION(S) : Catheter choice in an IVF-ET program does not influence success rate. Most important variable
affecting success rate is the number of embryos transferred.
