目的探讨体外受精-胚胎移植(IVF-ET)过程中子宫内膜厚度与临床妊娠率的相关性。方法回顾分析246周期患者的临床资料,根据HCG注射日子宫内膜厚度将患者分为三组:A组(<7mm),B组(7～14mm),C组(>14mm)。分别比较三组的临床妊娠率。结果 B组的临床妊娠率高于A组和C组,差异有统计学意义(P<0.05)。结论IVF-ET过程中,超声检查能准确地显示子宫内膜厚度,子宫内膜厚度7～14mm有利于胚胎着床。
Objective To investigate the correlation between endometrial thickness and clinical pregnancy rate during in vitro fertilization-embryo transfer (IVF-ET). Methods The clinical data of patients with 246 cycles were retrospectively analyzed. The patients were divided into three groups according to the thickness of endometrium on HCG injection day: group A (<7mm), group B (7 ~ 14mm) and group C (> 14mm). The clinical pregnancy rates of the three groups were compared. Results The clinical pregnancy rate in group B was higher than that in group A and C (P <0.05). Conclusions During the process of IVF-ET, ultrasonography can accurately display the thickness of endometrium, and the thickness of endometrium is 7-14mm, which is in favor of embryo implantation.
