摘 要:目的 探讨辅助生殖技术(assisted reproductive technology,ART)助孕后单胎妊娠发生早期自然流产的相关因素。方法 对2003年1月1日至2008年8月31日在本院生殖中心行常规体外受精/卵母细胞浆内单精子注射的新鲜胚胎移植周期治疗后的1636例单胎妊娠病例进行分析,除外失访、子宫畸形、赠卵、晚期流产及资料不齐全者后,分为早期流产组(n=196)和活产分娩组(n=1195),分析早期流产的相关因素。同时,比较新鲜胚胎移植周期和冷冻胚胎复苏移植周期(n=386)的流产率。结果 多因素Logistic回归分析早期自然流产的危险因素是孕妇年龄(OR=1.143,95%CI:1.096~1.196)、多囊卵巢综合征因素不孕(OR=4.309,95%CI:2.564~7.243),保护因素是移植胚胎的平均评分(OR=0.808,95%CI:0.717-0.912)、人绒毛膜促性腺激素(human chorionic gonadotropin,hCG)注射日子宫内膜三线型(OR=0.431,95%CI:0.243~0.764)。早期流产组和活产分娩组孕妇的年龄[(32.22±4.10)岁和(30.28±3.66)岁]、不孕年限[(5.90±4.26)年和(5.20±3.32)年]、基础卵泡刺激素水平[(6.35±2.30)mIU/ml和(5.95±2.12)mIU/ml]、移植胚胎数[(2.31±0.51)个和(2.18±0.49)个]、hCG注射日雌二醇水平[(2467.1±1588.8)pg/ml和(2934.5±1785.2)pg/m1]、胚胎平均评分(7.03±1.35和7.74±1.25)比较,差异均有统计学意义(P〈0.05),冷冻胚胎复苏移植周期流产率高于新鲜周期[17.36%(67/386)和13.02%(213/1636),X2=4.296,P=0.023]。结论 年龄大、不孕年限长、基础卵泡刺激素高、多囊卵巢综合征因素不孕、移植胚胎的平均评分低、hCG注射日子宫内膜非三线型的妇女ART妊娠后易发生早期流产。冷冻胚胎复苏移植周期的早期自然流产率高于新鲜胚胎移植周期。Objective To investigate the relative risk tactors tot early abortion among singleton pregnancies after assisted reproductive technology (ART) treatment. Methods A retrospective analysis was performed on 1636 singleton pregnancies, including 196 early abortion cases and 1195 pregnancies with live birth after exclusion of those lost cases during follow-up, or complicated with uterine deformity, or oocyte receptor, or late abortion, or incomplete medical record, following in vitro fertilization(IVF)/ intracytoplasmic sperm injection (ICSI) treatment and the risk factors of early abortion were investigated. The early abortion rate was also compared between fresh IVF/ICSI group and frozen embryo transfer (FET) group (n=386). Results Multivariate Logistic regression analysis indicated that elder women (OR=1. 143,95%CI: 1. 096-1.196) and patients with polycystic ovarian syndrome (OR=4.309,95%CI:2. 564-7.243) were risk factors of spontaneous early abortion, and high mean score of transferred embryos (MSTE) (OR=0.808, 95%CI: 0.717- 0.912) and endometrial triple-lined pattern on the day of human chorionic gonadotropin (hCG) administration (OR=0.431, 95% CI: 0.243-0.764)were protective factors. Significant difference were found in the maternal age [(32.22±4.10) yrs vs (30.28±3.66) yrs], the duration of infertility [(5.90±4.26) yrs vs (5.20±3.32) yrs], basal serum follicle-stimulating hormone (FSH) level [(6.35±2.30) mIU/ml vs (5.95±2.12) mIU/ml], number of transferred embryos (2.31±0.51) vs (2. 18±0.49), serum estradiol level on the day of hCG administration [(2467.1±1588.8) pg/ml vs (2934.5±1785.2) pg/ml] and MSTE (7.03±1.35 vs 7.74±1.25) between the abortion group and livebirth group (all P〈0.05). The spontaneous abortion rate was higher in the FET group than in the fresh embryo transfer group [17.36±(67/386) vs 13.02±(213/1636), X2=4.296, P=0.023].
