摘要: 目的:探讨体外受精-胚胎移植(IVF-ET)中各因素与单卵双胎(monozygotic twins,MZT)妊娠的相关性。方法:对本中心3 966个妊娠周期(含MZT 35例)和另30例(含MZT 1例)胚胎植入前遗传学诊断(PGD)妊娠周期的临床资料行非条件Logistic回归分析,筛选单卵双胎发生的相关因素。回顾分析11 423个新鲜胚胎移植周期的临床资料,将其分为激光辅助孵化(AH)组和未行辅助孵化(非AH)组,比较2组中IVF周期和胞浆内单精子注射(ICSI)周期的单卵双胎发生率。结果:Logistic回归分析结果表明ICSI-AH(OR=1.039,95%CI:1.013~1.065)可能是IVF中单卵双胎妊娠发生的危险因素。非AH组行IVF 4 624个周期,ICSI 1 571个周期;AH组行IVF 3 807个周期,ICSI 1 421个周期,2组组内患者基本情况差异无统计学意义(P>0.05)。非AH组IVF与ICSI周期临床妊娠率(40.72% vs. 42.76%)和单卵双胎率(0.69% vs. 0.75%)差异均无统计学意义(P>0.05);AH组IVF与ICSI周期临床妊娠率(27.97% vs. 29.77%)差异无统计学意义(P>0.05),但ICSI周期的单卵双胎率高于IVF周期(2.31% vs. 0.66%,P<0.05)。结论:行激光辅助孵化的ICSI周期可能增加单卵双胎发生率。

Abstract: Objective: To investigate the correlation between those risk-factors of in vitro fertilization-embryo transfer (IVF-ET) and monozygotic twins (MZT) gestation. Methods:3 966 clinical pregnancy cycles,including 36 MZT cycles,were analyzed by Logistic regression. According to fertilization methods and with or without laser-assisted hatching (LAH),total of 11 423 IVF/intracytoplasmic sperm injection (ICSI) cycles were divided into nonAH-IVF group (4 624 cases),nonAH-ICSI group (1 571 cases),LAH-IVF group (3 807 cases) and LAH-ICSI group (1 421 cases). The incidences of MZT were compared. Results:LAH-ISCI (OR=1.039,95%CI:1.013~1.065) may be a risk factor of MZT pregnancy in IVF-ET. There were no significant differences in general condition between nonAH groups and LAH groups,and no significant differences in clinical pregnancy rate (40.72% vs. 42.76%) and MZT rate (0.69% vs. 0.75%) between nonAH-IVF group and nonAH-ICSI group (P>0.05). MZT rate was significantly higher in LAH-ICSI group than that in LAH-IVF group (2.31% vs. 0.66%,P<0.05),while there was no significant difference in the pregnancy rate between the two groups (27.97% vs. 29.77%,P>0.05). Conclusions:LAH-ICSI might increase the occurrence of MZT.
