摘要:

目的:探讨玻璃化冷冻保存卵裂期胚胎的时间对冻融胚胎移植结局的影响。方法:回顾性分析2017年1月—2020年12月山西医科大学第一医院生殖医学中心进行卵裂期胚胎玻璃化冷冻复苏移植的3 847个周期,包括8 767枚冻融胚胎。根据胚胎冻存时间分为5组,≤1年组,(1~2]年组、(2~3]年组、(3~4]年组和>4年组,比较各组患者的一般情况、胚胎解冻复苏情况及临床结局的差异,并采用二分类Logistic回归分析取卵年龄、移植年龄、冻存时间、移植胚胎数和优质胚胎数对移植结局的影响。结果:各组患者取卵年龄、移植年龄、移植胚胎数、临床妊娠率及活产率比较,差异有统计学意义(P<0.05)。Logistic回归分析显示取卵年龄、移植年龄、冻存时间对临床妊娠、活产无影响(P>0.05),移植胚胎数及优质胚胎数对临床妊娠、活产有影响(P<0.05)。结论:玻璃化冷冻保存卵裂期胚胎的时间对胚胎复苏及妊娠结局没有显著影响。

Abstract:

Objective: To explore the effect of vitrification cryopreservation time on the outcome of cleavage embryo transfer. Methods: From January 2017 to December 2020, 3 847 cases of vitrification cryo-resuscitation transfer of cleavage embryos, including 8 767 freeze-thaw embryos, were performed in Reproductive Medicine Center, The First Hospital of Shanxi Medical University. According to the cryopreservation time of embryos, the embryos were divided into 5 groups: group 1 was ≤1 year, group 2 1-2 years, group 3 2-3 years, group 4 3-4 years and group 5 >4 years. The general situation of patients, embryo thawing and recovery and clinical outcomes were compared among the groups. Logistic regression analysis was used to analyze the effect of maternal age at oocyte retrieval and embryo transfer, embryo cryopreservation time, the number of transferred embryos or high-quality embryos on the pregnancy outcome. Results: There were significant differences in the maternal age at oocyte retrieval and embryo transfer, the number of transferred embryos, pregnancy rate and live birth rate (P<0.05). Logistic regression analysis showed that maternal age at oocyte retrieval or embryo transfer, and embryo cryopreservation time had no significant effect on the pregnancy rate and live birth rate (P>0.05), while there were significant differences in the number of transferred embryos and high-quality embryos (P<0.05). Conclusions: The duration of vitrification cryopreservation had no significant effect on the cleavage stage embryo resuscitation and pregnancy outcome.
