摘要:

目的: 探讨氯米芬微刺激方案体外受精/卵细胞质内单精子注射(IVF/ICSI)周期中获得成熟卵母细胞及可移植胚胎的预测因子。方法: 收集2014年1月—2015年12月在南京大学医学院附属鼓楼医院生殖医学中心采用氯米芬微刺激方案促排卵且成功获卵的IVF/ICSI患者的1 029个周期的临床资料,分析患者基本情况、促排卵参数与获得成熟卵母细胞及可移植胚胎的相关性。结果: 人绒毛膜促性腺激素(hCG)日最大优势卵泡直径(P=0.024)、优势卵泡数(P<0.001)、优势卵泡雌二醇(E2)水平(P=0.003)是获得成熟卵母细胞的独立预测因子。hCG日最大优势卵泡直径(P=0.031)和优势卵泡数(P<0.001)是获得可移植胚胎的独立预测因子。hCG日E2水平是单个卵泡发育周期获得可移植胚胎的独立预测因子(P=0.018)。受试者工作特征(ROC)曲线分析提示,单个卵泡发育周期中hCG日E2水平预测有可移植胚胎的最佳临界值为1 931.25 pmol/L,ROC曲线下面积(AUC)为0.605,预测获可移植胚胎的敏感度为74.4%,特异度为46.3%,高于最佳临界值组可移植胚胎率(52.08%)显著高于低于最佳临界值组(30.28%),差异有统计学意义(P<0.001)。结论: 氯米芬微刺激方案中hCG日最大优势卵泡直径越大、优势卵泡数越多、优势卵泡E2水平越高获得成熟卵母细胞的概率越大,hCG日最大优势卵泡直径越大和优势卵泡数越多获得可移植胚胎的概率越大;单个卵泡发育周期hCG日E2水平越高获得可移植胚胎的概率越大。

Abstract:

Objective: To study the predictors of obtaining MⅡ oocytes or transferable embryos in the mild ovarian stimulation IVF/ICSI cycles with clomiphene citrate (CC). Methods: Clinical data of 1 029 cycles using CC mild ovarian stimulation protocol with the number of retrieved oocytes≥1 were collected in the Reproductive Medicine Center of Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2014 to December 2015. The baseline characteristics, ovarian stimulation parameters and obtaining MⅡ oocytes or transferable embryos, as well as their relations, were analyzed. Results: The dominant follicle size on trigger day (P=0.024), the number of dominant follicles on trigger day (P<0.001), and the average E2 level of dominant follicles on trigger day (P=0.003) were independent predictors of obtaining MⅡ oocytes, while the dominant follicle size on trigger day (P=0.031) and the number of dominant follicles on trigger day (P<0.001) were independent predictors of obtaining transferable embryos. In single dominant follicle cycles, the E2 level on trigger day was an independent predictor of obtaining transferable embryos (P=0.018). ROC curve analysis showed that the optimal cut-off value of E2 level on trigger day for predicting transferable embryos in single dominant follicle cycles was 1 931.25 pmol/L and AUC was 0.605. The sensitivity was 74.4%, and the specificity was 46.3%. The transferable embryo rate was higher in the group of E2 level on trigger day above the optimal threshold (52.08% vs. 30.28%, P<0.001). Conclusions: In the mild ovarian stimulation with CC, the larger the diameter of the dominant follicle size on trigger day, the greater the number of dominant follicles on trigger day and the higher E2 level of dominant follicles on trigger day, the larger the probability of obtaining MⅡ oocytes. The larger the diameter of the largest dominant follicle and the greater the number of dominant follicles on trigger day, the larger the probability of obtaining transferable embryos. In single dominant follicle cycles, the higher E2 level on trigger day, the greater the probability of obtaining a transferable embryo.
