摘要
目的分析体外受精(IVF)或卵母细胞胞质内单精子注射(ICSI)后进行新鲜或冻融胚胎移植(ET)妇女异位妊娠的发生情况及其影响因素。方法选择2005年1月至2010年12月在郑州大学第一附属医院生殖医学中心接受IVF—ET或ICSI—ET助孕治疗患者的9037个新鲜ET周期(新鲜周期组)、4034个冻融ET周期(冻融周期组),比较两组异位妊娠发生率、新鲜周期组内IVF周期(5998个)和ICSI周期(3039个)异位妊娠发生率及冻融周期组内自然周期(2198个)和激素替代(E—P)周期(1836个)异位妊娠发生率。结果冻融周期组4034个周期中,临床妊娠1090个周期,发生异位妊娠26个周期,异位妊娠发生率为2.38%(26/1090),新鲜周期组9037个周期中,临床妊娠3602个周期,发生异位妊娠133个周期,异位妊娠发生率为3.69%(133/3602),两组异位妊娠发生率比较,差异有统计学意义(P〈0.05)。新鲜周期组内3039个ICSI—ET周期中,临床妊娠1298个周期,异位妊娠发生率为2.62%(34/1298),5998个IVF—ET周期中,临床妊娠2304个周期,异位妊娠发生率为4.30%(99/2304),不同助孕方式的异位妊娠发生率比较,差异也有统计学意义(P〈0.01);冻融周期组内2198个自然周期中,临床妊娠547个周期,异位妊娠发生率为1.46%(8/547),1836个E—P周期中,临床妊娠543个周期,异位妊娠发生率为3.31%(18/543),两者比较,差异也有统计学意义(P〈0.05)。结论冻融周期ET后异位妊娠发生率明显低于新鲜周期ET;助孕治疗中外源性激素的应用,可能是引发异位妊娠的重要影响因素之一。
Objective To investigate ectopic pregnancy from embryo transfer (ET)of in-vitro fertilization (IVF) cycle and intracytoplasmic sperm injection (ICSI) cycle and frozen-thawed (FET) cycle. Methods From Jan. 2005 to Dec. 2010, a total of 9037 IVF-ET or ICSI-ET cycles and 4034 FET cycles were performed in our reproductive medicine center, Affiliated First Hospital of Zhengzhon University. The incidence of ectopic pregnancy rate was studied in fresh cycles IVF-ET (5998) and ICSI-ET (3039) cycles, and natural FET (2198) and hormone replacement (E-P) FET (1836) cycles. Results Of 4034 FET cycles, 1090 clinical pregnancies and 26 ectopic pregnancies were observed, the incidence of ectopic pregnancy was 2. 38% (26/1090). Of 9037 fresh cycles, 3602 cycles were clinical pregnancy, and 133 cycles were ectopic pregnancy, and the incidence of ectopic pregnancy was 3.69% (133/3602). The ectopic pregnancy rate in FET cycles was lower than in fresh cycles significantly ( P 〈 0. 05 ). Of 3039 fresh ICSI-ET cycles, the incidence of ectopic pregnancy was 2. 62% ( 34/1298 ) in 1298 clinical pregnancies. Of 5998 IVF-ET cycles, 2304 clinical pregnancies were observed, the incidence of ectopic pregnancy was 4. 30% (99/2304). Ectopic pregnancy rate in the fresh ICSI-ET cycles was lower than that of IVF-ET group significantly (P 〈0. 01 ). The ectopic pregnancy rate in the natural FET cycles was 1.46% (8/547), which was significantly lower than 3.31% ( 18/543 ) in E-P group ( P 〈 0. 05 ). Conclusions The incidence of ectopic pregnancy of FET cycles was significantly lower than that of fresh embryo transfer cycles. The application of exogenous sex hormones in assisted reproductive cycles might increase occurrence of ectopic pregnancy.
