Abstract
Objectives: To compare reproductive outcomes using two different soft catheters ie Set TDT® and Cook® Sydney IVF. The primary outcome was defined as a positive beta-human chorionic gonadotropin (beta-hCG) test.
Methods: Our prospective study recruited 68 patients undergoing in vitro fertilization cycles in a private fertility clinic in Porto Alegre, Brazil, between January 2014 and April 2016. They were divided into two groups according to the catheter that would be used for the embryo transfer and groups were matched for age. The total of patients in each group was: 34 for TDT and 34 for Cook Sydney. All the patients were submitted to a beta-hCG test 12 days after the embryo transfer for pregnancy outcome evaluation.
Results: 10 out of 34 patients of TDT group had a positive outcome for pregnancy, corresponding to 29.4%. The Cook Sydney group had 9 patients out of 34 with positive outcome, corresponding to 26.5%. Comparing the efficacy of both catheters for the primary outcome, there was no significant difference (P>0.05) between TDT and Cook Sydney catheters.
Conclusion: The efficacy of TDT and Cook Sydney catheters are similar for embryo transfer during assisted reproductive technology cycles.
