基础血清抗苗勒管激素与新鲜/冷冻胚胎移植周期活产率的相关性分析

摘要

[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po⁃tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro⁃zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.%【目的】探讨基础血清抗苗勒管激素（AMH）水平与新鲜周期和冷冻周期活产率的关系及血清AMH水平对胚胎移植的活产率的预测价值。【方法】选取2010年6月-2015年5月在我生殖中心进行第一次新鲜或冷冻胚胎移植周期的不孕患者共2942例进行回顾性分析。排除多囊卵巢综合征的患者。根据不孕患者的血清AMH水平分为低AMH水平组（<1.1 ng/mL，485例），中AMH水平组（1.1~7.0 ng/mL，1989例）及高AMH水平组（>7.0 ng/mL，468例）。再根据年龄将患者分成不同的年龄亚组：A组：≤29岁，B组：30~34岁，C组：35~39岁及D组：40岁以上。比较同一年龄组内不同血清AMH水平的种植率、临床妊娠率、流产率及活产率的差异。进一步采用多元回归分析方法分析基础血清AMH对活产率的影响。利用受试者工作特征曲线分析（ROC），评估血清AMH对活产率的预测价值。【结果】（1）在新鲜胚胎和冷冻胚胎移植周期，基础血清AMH水平均与临床妊娠结局相关，血清AMH水平越低，种植率越低，同样临床妊娠率越低，活产率越低，而流产率则越高，差异均有统计学意义。（2）年龄亚组分析显示，在新鲜及冷冻周期，A、B及C组的患者的基础血清AMH与活产率相关，AMH越低，活产率越低，差异均有统计学意义。D组患者的基础血清AMH与冷冻周期的活产率相关（P<0.05），与新鲜周期的活产率无关（P=0.092）。多元回归分析显示，在纳入了年龄、不孕年限、不孕原因、移植胚胎数、内膜准备方案等影响结局的因素后，血清AMH对活产率的影响仍保持有统计学意义。（3）基础血清AMH预测新鲜周期及冷冻周期胚胎移植活产率的受试者工作特征曲线（ROC）下面积分别为0.647、0.633。【结论】基础血清AMH是反映卵巢储备的良好指标之一，与胚胎移植周期的妊娠结局有相关性，基础血清AMH水平越低，活产率越低。基础血清AMH是影响胚胎移植周期活产率的独立影响因素，但对活产率的预测价值有限。
