Improvement of pregnancy rate by modification of embryo transfer technique: a randomized clinical trial.
In this randomized trial study, two groups of infertile women (n=55) aged≤40 years underwent in vitro fertilization or intracytoplasmic sperm injection treatment cycles with or without 0.2 mL of air pushed into the catheter after embryo transfer. The implantation and clinical pregnancy rates were statistically significantly higher in the study group than in the controls. This improvement on standard ET technique may advance clinical pregnancy rates.
