目的:研究胚胎移植日子宫内膜蠕动波频率(UPF)对冻融胚胎移植妊娠结局的影响。方法:对166个行自然周期及替代周期冻融胚胎移植(FET)者于胚胎移植(ET)日阴道B超下监测子宫内膜蠕动波5 min,同时测定患者ET日的子宫内膜厚度、血清雌二醇(E2)及孕酮(P)水平。结果:所有FET周期中未妊娠组患者ET日UPF高于妊娠组;ET日UPF在1~2次/min时临床妊娠率最高;替代周期组ET日UPF高于自然周期组,但无统计学差异(P>0.05)。FET妊娠结局相关因素的Logistic回归证实ET日UPF是影响妊娠结局的危险因素。结论:FET周期ET日适度低频UPF预示良好的妊娠结局。
Objective: To study the effect of endometrial percussion wave frequency (UPF) on pregnancy outcome of embryo transfer frozen embryo transfer. Methods: 166 patients with natural cycles and frozen-thawed embryo transfer (FET) were monitored by vaginal ultrasonography for 5 min on embryo transfer (ET), and endometrial thickness was measured at ET. Serum estradiol (E2) and progesterone (P) levels. Results: In all FET cycles, the UPF of ET in pregnant women was higher than that of pregnant women. The highest pregnancy rate of UPF was at 1 ~ 2 times / min on ET day. The UPF of ET on alternate days was higher than that of natural cycles Difference (P> 0.05). Logistic regression of FET-related pregnancy outcomes confirmed that UPF-UP was a risk factor for pregnancy outcome. Conclusion: Moderate low frequency UPF of FET cycles ET indicates good pregnancy outcome.
