目的:分析玻璃化冷冻的卵母细胞在供卵周期中的临床结局,以期为卵母细胞捐献的临床应用提供参考。方法:回顾性分析2006年2月—2014年10月南京医科大学第一附属医院临床生殖医学中心216个供卵周期的玻璃化冷冻的卵母细胞,比较解冻后的复苏率、行体外受精-胚胎移植(in vitro fertilization-embryo transfer,IVF-ET)的正常受精率、累计临床妊娠率、种植率和累计活产率等临床结局。结果:解冻玻璃化冻存的卵母细胞的复苏率为82.0%(899/1 097),二原核(2PN)受精率76.9%(691/899)。在216个周期中,胚胎种植率为21.4%(84/393),累计临床妊娠率为33.3%(72/216),累计活产率达27.3%(59/216)。每解冻1枚卵母细胞获得活产儿的概率为6.5%(71/1 097)。结论:卵母细胞玻璃化冻融技术在卵母细胞捐赠的临床应用上可以获得较好的临床结局。

【Abstract】Objective:To analyse the clinical outcomes of the ovum donation cycles conducted with the vitrified oocytes,so as to provide the predictive information for the clinical application of this technique.M ethods: The clinical outcomes of 216 ovum donation cycles,which conducted with the vitrified-thawed oocytes undergoing IVF-ET in our reproductive center from February 2006 to October 2014,were retrospective analyzed.The main outcome parameterswere the survival rate of the freezen-thawed oocytes,the normal fertilization(2PN)rate of in vitro fertilization,the cumulative clinical pregnancy rate,the implantation rate and the cumulative live birth rate. Results:The survival rate of the freezen-thawed oocytes was 82.0%(899/1 097).The normal fertilization(2PN)rate was 76.9%(691/899).The rates of implantation,cumulative clinical pregnancy and live birth were 21.4%(84/393),33.3%(72/216)and 27.3%(59/216),respectively.The oocyte-to-baby rate was 6.5%(71/1 097).Conclusions: There is relatively good clinical outcomes of the freezen-thawed oocyteswhen applied in the ovum donation.

自1986年世界上第1例冻卵试管婴儿诞生以来[1],人卵母细胞冷冻保存技术取得了极大进步。截止2008年文献报道的全球出生的冻卵试管婴儿有900多例[2]。目前,玻璃化冷冻技术已成为冷冻保存卵母细胞的金标准[3]。卵母细胞的捐献为卵巢功能早衰、卵巢功能不全或遗传疾病妇女获得赠卵诞生新生命带来了希望[1]。南京医科大学第一附属医院生殖中心在国内率先开展了卵母细胞玻璃化冷冻-捐赠分享技术[4-5]。本研究回顾性分析了该技术开展之初的216个供卵周期的临床数据,以期为今后更好地改善供卵周期的临床结局提供参考依据。……
