Embryo transfer is the most emotional part for patients during fertilization treatment. Over the last decade, the embryo transfer procedure has undergone numerous changes in the guidelines in order to increase pregnancy rates. One such procedure is the loading of the embryo into the catheter, a thin tube that helps us transfer embryo into the uterine cavity. Very few research studies looked closely at embryo-loading technique per se. Furthermore, different infertility laboratories use various techniques to load embryo. The aim of our study was to compare the two most popular embryo-loading techniques. In 249 women, we transferred embryo aspirated into the catheter with small droplets of air, and in the group of 244 patients, we filled catheter only with fluid. Our main outcome measured was the clinical pregnancy rate. Based on our results, we did not find that embryo-loading technique affected patient's chances of achieving pregnancy.
胚胎移植是患者在受精治疗过程中最情绪化的部分。在过去的十年中，胚胎移植程序在指南中发生了许多变化，以提高妊娠率。其中一种程序是将胚胎装入导管，这是一种帮助我们将胚胎转移到子宫腔的细管。很少有研究仔细研究胚胎装载技术本身。此外，不同的不孕不育实验室使用不同的技术来装载胚胎。我们的研究目的是比较两种最流行的胚胎装载技术。在 249 名女性中，我们将吸入导管中的胚胎与少量空气滴一起转移，在 244 名患者组中，我们仅用液体填充导管。我们测量的主要结果是临床妊娠率。根据我们的结果，我们没有发现胚胎装载技术会影响患者怀孕的机会。
