[摘要] 目的 探讨长效长方案促排卵周期中,冲洗卵泡对患者胚胎发育情况影响。 方法 回顾性分析2014年 7月~2016年6月在广东医科大学附属医院生殖中心接受长效长方案试管婴儿(IVF)助孕的343例女性的临床资料,其中采用卵泡冲洗99例(冲洗组),采用直接吸取卵泡液244例(对照组)。对两组患者获卵率、正常受精(2PN)卵率、2PN卵裂率、优胚率、囊胚率、胚胎可利用率、临床妊娠率、着床率和流产率进行分析。 结果 在长效长方案促排卵周期中,冲洗组的卵裂胚胎利用率、优胚率、囊胚冷冻率均显著高于对照组,差异有统计学意义(P < 0.05),其他实验室和临床各项指标间差异无统计学意义(P > 0.05)。 结论 在长效长方案促排卵周期中,冲洗卵泡并不能使获卵率增加,但能有效提高卵裂胚胎的利用率,优胚率和囊胚冷冻率,患者临床妊娠率和种植率均有增高趋势。

[Abstract] Objective To evaluate the effects of follicle flushing on embryonic development in patients of long protocol controlled ovarian hyperstimulation in vitro fertilization. Methods From July 2014 to June 2016, in Reproductive Medicine Center, Affiliated Hospital of Guangdong Medical University, the clinical data of 343 patients underwent in vitro fertilization (IVF) were analyzed retrospectively. Among them,99 patients treated with G-MOPs were set as follicle flushing group, and 244 patients sucked direethy folliculer fluid were as control group. The oocyte retrieval rate, fertilization rate, 2PN cleavage rate, good quality embryo rate, blastocyst rate, available embryo rate, clinical pregnancy rate, implantation rate, abortion rate of two groups were compared. Results The available embryo rate, good quality embryo rate and blastocyst rate in follicle flushing group were higher than those in control group, the differences were statistically significant (P < 0.05), and other clinical and lab indication also checking had no statistical difference between the two groups (P > 0.05). Conclusion Follicle flushing is not necessary to increase the oocyte retrieval rate, but can increase the available embryo rate, good quality embryo rate and blastocyst rate, it showes a increased tendency gradually of clinical pregnancy rate and implantation rate.

陰道B超引导下取卵术已成为辅助生殖技术(ART)中采集卵子的标准方法,卵泡冲洗技术在ART中也是一项基本技术。许多研究者认为卵泡冲洗可提高卵母细胞的采集率[1-2]。但也有研究者表示,卵泡冲洗通常会延长取卵手术时间,并未增加患者的获卵率和临床妊娠率[3]。在这种情况下,许多中心都面临这样的问题,取卵术中是否需要进行卵泡冲洗,卵泡冲洗获得的卵母细胞发育潜能是否受到影响。本研究回顾性分析在广东医科大学附属医院(以下简称“我院”)生殖中心接受长效长方案试管婴儿(IVF)助孕的女性的临床资料,比较卵泡冲洗对患者卵子回收、胚胎发育潜能和临床结局的影响。……
