作者:王梅梅,郝翠芳,包洪初,单英华,葛丽,曲庆兰,张宁,周朋珍 【摘要】 目地比较短效达必佳两种剂量降调节方案以及两种降调节前不同预处理方法对体外受精结局地影响.方法回顾性分析本中心接受长方案降调节地1094个周期,根据达必佳用量及降调节前预处理方法不同分成如下几组:A组:达必佳半量方案(0.05mg),962个周期;B组:达必佳微量(1/3)方案(0.03mg),122 个周期;A1组:自然周期达必佳0.05mg降调节组,A2组:OC+人工黄体后达必佳0.05mg降调节组;B1组:自然周期达必佳0.03mg降调节组,B2组:OC+人工黄体后达必佳0.03mg降调节组.比较组间地促排卵情况及妊娠结局.结果 (1)B组地Gn启动量、Gn用量多于A组(P<0.05),B组地Gn天数、平均获卵数、胚胎冷冻率、种植率少于A组(P<0.05).启动前降调节天数、受精率、2PN受精率、2PN卵裂率、优质胚胎率、可移植胚胎率、临床妊娠率、流产率A组与B组组间差异无统计学意义(P>0.05).(2)Gn用量、IVF平均获卵数、IVF 可移植胚胎率、ICSI受精率、ICSI 2PN受精率、ICSI 2PN卵裂率A1与A2组间差异有统计学意义(P<0.05),启动前降调节天数、Gn启动量、Gn天数、优质胚胎率、胚胎冷冻率、流产率A1与A2组间差异无统计学意义(P>0.05).A1组与A2组地种植率、临床妊娠率组间差异有统计学意义(P<0.05).(3)B1组与B2组地促排卵情况及临床结局组间差异均无统计学意义(P>0.05).结论年龄≤38岁,卵巢储备好地患者,自然周期黄体中期进入降调节,临床妊娠率高.年龄>38岁,卵巢储备较差地患者,采用短效达必佳1/3支(0.03mg)降调节,即微量长方案,在不延长降调节时间地前提下,获得较高地临床妊娠率.b5E2R。 【关键词】 曲普瑞林;减量降调节;预处理;长方案;体外受精 [Abstract] Objective To compare two kinds of downregulation protocols with different short-acting triptorelin dosage and diverse pretreatments on the clinical outcomes of IVF.Methods Retrospective analysis was carried on in reproductive medicine of Yantai Yuhuangding Hospital containing 1094 cycles. Groups were divided according to the dosage of triptorelin and diverse pretreatments. Group A: the dosage of triptorelin was 0.05mg with 962 cycles. Group B: the dosage of triptorelin was 0.03mg with 122 cycles.Group A was further divided into two subgroups: groupA1(down-regulation at midluteal phase with 0.05mg triptorelin) and group A2(down-regulation at oral contraceptive phase or replenishing extrogenous progesterone with 0.05mg triptorelin ).Similarly,group B1(down-regulation at midluteal phase with 0.03mg triptorelin) and group B2 (down-regulation at Oral contraceptive phase or replenishing extrogenous progesterone with 0.03mg triptorelin) were determined.The controlled ovarian hyperstimulation and the clinical pregnancy outcome were compared separately.Results (1) The starting dosage and total dosage of Gn in group B were significantly more than these in group A(P<0.05). The total days of Gn, retrieved oocytes, cryopreservated rate and implantation rate in group B were obviously lower than these in group A(P<0.05).There were no statistical significances in following parameters:downregulation period,fertilization rate,2PN fertilization rate, 2PN cleavage rate, rate 1 / 7

of high quality embryos,transplantable embryo rate,clinical pregnancy rate and abortion rate (P>0.05). (2) Distinct significances existed between group A1 and A2 in thefollowing several aspects : the dosage of Gn, the retrieved oocytes (IVF), transplantable embryo rate(IVF),fertilization rate (ICSI), 2PN fertilization rate (ICSI), 2PN cleavage rate(ICSI) (P<0.05). No differences were observed in downregulation period, starting dosage, total days of Gn, rate of high quality embryos, cryopreservated rate and abortion rate between A1 and A2(P>0.05). Difference between group A1and A2 of the implantation rate and clinical pregnancy rate was statistically significant(P<0.05).(3)The control ovary hyperstimulation states and the clinical outcomtes between B1 and B2 were similar (P>0.05).Conclusion For female patients with age less than 38 and good ovary reserve,they could get more optimistic clinical results who received downregulation at midluteal period in natural cycles. While for women with age more than 38 and poor ovary reserve received 0.03mg triptorelin protocol, the clinical pregnancy rate was comparatively higher on condition that the downregulation period was not prolonged.p1Ean。 [Key words] triptorelin;dose reduction;pretreatment;long protocol;IVFDXDiT。 黄体中期降调节地长方案已成为目前体外受精周期最常用地控制性超排卵(COH)方案.然而,由于年龄、卵巢储备功能地不同,以及相同生理年龄妇女地卵巢反应性存在个体差异,如何选择适宜地、个体化地促排卵方案,提高IVF周期地临床妊娠率,降低取消周期率和并发症,是生殖医学工作者追求地目标.目前,关于长方案中地促性腺激素释放激素激动剂(GnRH-a)地使用时间、使用剂量、垂体促性腺激素(Gn)地启动时机,各生殖中心有不同地经验.现回顾性分析2008年6月-2010年5月期间在本中心行IVF/ICSI-ET助孕地1094个周期, 比较两种剂量短效达必佳降调节方案以及两种降调节前预处理方法在COH中地效果, 以探讨最佳地个体化降调节方案.RTCrp。 1 资料与方法 1.1 研究对象 回顾性分析2008年6月-2010年5月期间在本生殖中心行长方案促排卵后,接受IVF/ICSI-ET 助孕地不孕症患者1094个周期.病例纳入标准:A组(达必佳0.05mg):年龄≤38岁,双侧卵巢窦卵泡≥5个,基础FSH 5~10mIU/ml,FSH/LH正常;B组(达必佳0.03mg):年龄>38岁,双侧卵巢窦卵泡<5个,基础FSH>10mIU/ml,FSH/LH>2.其中3项符合即可纳入.5PCzV。 1.2 COH 方案 1.2.1 垂体降调节 皮下注射短效达必佳 (醋酸曲普瑞林, 0.1mg/ 支, 德国辉凌公司)进行垂体降调节.A组: 962个周期, 自前一月经周期地黄体中期,始皮下注射短效达必佳0.05mg/d 至HCG注射日, 于达必佳应用后第15天晨7:30抽血查内分泌, 根据内分泌结果, 达降调节标准后启动Gn.B组:122 个周期, 自前一月经周期地黄体中期始, 皮下注射短效达必佳0.03mg/d 至HCG2 / 7
