摘要
目的探讨亚临床甲状腺功能减退(subclinical hypothyroidism,SCH)对辅助生殖妊娠结局的影响。方法回顾性分析2010年2月至2011年2月在中南大学湘雅医院生殖医学中心接受体外受精-胚胎移植/卵胞浆内单精子显微注射(IVF-ET/ICSI)治疗患者的资料,其中82名亚临床甲减患者列入研究组,398名甲状腺功能正常者列入对照组,比较两组患者的各实验室及临床指标,分析亚临床甲减对辅助生殖妊娠结局的影响。结果(1)两组患者的一般情况比较无统计学差异。(2)两组患者的IVF-ET/ICSI正常受精率、卵裂率、优质胚胎率、种植率、临床妊娠率、流产率、卵巢过度刺激综合征(OHSS)发生率、平均单胎分娩总孕天数比较均无统计学差异(P>0.05);虽未达到统计学差异,但研究组的流产率、OHSS发生率高于对照组,分别为24.24%vs.15%、14.63%vs.10.1%;其中研究组的生化妊娠率显著高于对照组(11.8%vs.4.4%)(P<0.05),单胎新生儿平均出生体重明显低于对照组[(3,147.6±79.6)g vs.(3,224.9±56.5)g](P<0.05)。结论亚临床甲减患者行IVF-ET/ICSI治疗生化妊娠率、低出生体重儿发生率明显增高,流产率、OHSS发生率呈上升趋势。因此需对亚临床甲减患者IVF-ET/ICSI治疗过程及孕期进行严密监测,预防促排卵并发症及不良妊娠结局的发生。
Objective: To explore the effect of subclinical hypothyroidism(SCH)on pregnancy outcome in infertile patients undergone assisted reproductive technology. Methods: The data of 480 patients undergone in vitro fertilization-embryo transfer/intracytoplasmic sperm injection(IVF-ET/ICSI)from February 2010 to February 2011 in the reproductive medicine center of Xiangya Hospital were retrospectively analyzed. The IVF/ICSI outcomes were compared between the patients with subclinical hypothyroidism (study group, n = 82) and euthyroid patients (control group, n = 398). The influence of SCH on pregnancy outcome was analyzed. Results: (1)There was no significant difference in patient characteristics between the two groups; (2) The fertilization rate, cleavage rate, high quality embryo rate, implantation rate, clinical pregnancy rate, miscarriage rate, ovarian hyperstimulation syndrome(OHSS)rate, and gestational age of singleton births were not significantly different between the two groups. However,the miscarriage rate(24.24% vs. 15%) and OHSS rate(14.63% vs. 10. l%)in the study group were higher than those in the control group. In the study group, the biochemical pregnancy rate was significantly higher and the singleton birth weight was significantly lower compared with those in the control group(P〈0.05). Conclusions: The biochemical pregnancy rate and low birth weight rate are significantly higher in SCH patients undergone IVFET/ICSI. We should pay more attention to patients with SCH during controlledovarian hyperstimulation(COH)to prevent complication of COH and adverse outcome of IVF-ET/ICSI.
