摘 要:目的:探讨在体外受精-胚胎移植(IVF-ET)周期中促性腺激素释放激素拮抗剂(GnRH-ant)方案的自发排卵率,并分析自发排卵的高危因素。方法回顾性分析2012年1月至2015年12月中山大学附属第一医院在LVF-ET中使用GnRH-ant方案和促性腺激素释放激素激动剂(GnRH-a)长方案共10612个周期,计算GnRH-ant方案(2098个周期)的自发排卵总体情况,并与GnRH-a长方案(8514个周期)比较;进一步将GnRH-ant方案中发生自发排卵(自发排卵组)的周期(34个)与未发生自发排卵(未自发排卵组)的周期(136个)进行1∶4匹配的对照研究及二元logistic多因素回归分析,分析在GnRH-ant方案中发生自发排卵的高危因素。结果在总体人群中,GnRH-ant方案的自发排卵率为1.62%(34/2098),高于GnRH-a长方案的0.15%(13/8514),两者比较,差异有统计学意义(P〈0.01)。在进一步的对照研究中,自发排卵组患者的基础FSH水平显著高于未自发排卵组,中位基础FSH水平分别为10.7、7.2 U/L,两组比较,差异有统计学意义(P〈0.01)。二元logistic多因素回归分析提示,仅基础FSH水平是GnRH-ant方案中自发排卵的独立危险因素(OR=1.20,P=0.009)。结论在IVF-ET的促排卵方案中,GnRH-ant方案的自发排卵率约为GnRH-a长方案的10倍;较高的基础FSH水平是GnRH-ant方案使用过程中发生自发排卵的独立危险因素。Objective To investigate the premature spontaneous ovulation rates in in vitro fertilization-embryo transfer (IVF-ET) cycles using gonadotropin-releasing hormone antagonist (GnRH-ant) and gonadotropin-releasing hormone agonist (GnRH-a), as well as the risk factors for premature spontaneous ovulation. Methods The rates of premature spontaneous ovulation in a total of 10 612 cycles using GnRH-ant or GnRH-a were compared. Matched case-controlled study and binary logistic regression model were conducted to analyze the risk factors for premature spontaneous ovulation. Results The spontaneous ovulation rate in the whole for GnRH-a cycles was 0.15%(13/8 514), compared with a 1.62%(34/2 098) in GnRH-ant cycles (P〈0.01). Further matched controlled study and regression analyze found out that higher basal FSH level was a predominant risk and prediction factor for spontaneous ovulation (OR=1.20, P=0.009). Conclusions In GnRH-ant cycles, spontaneous ovulation rate is about 10 times than which in GnRH-a cycles. Diminished ovarian function is a predominate risk factor for premature spontaneous ovulation.
