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.
在这项随机试验研究中，两组年龄≤40 岁的不孕妇女（n=55）接受了体外受精或卵胞浆内单精子注射治疗周期，在胚胎移植后，研究组有 0.2 毫升空气被推入导管，而对照组没有。研究组的着床率和临床妊娠率明显高于对照组。这项对标准胚胎移植技术的改进可能会提高临床妊娠率。
