Abstract

Background: In in vitro fertilization (IVF), transferring frozen-thawed blastocysts is a widely adopted practice. This meta-analysis aims to evaluate the reproductive outcomes of transferring blastocysts derived from frozen-thawed cleavage embryos (FT-CDB group) compared to direct frozen-thawed blastocyst (DFB group) transfers.

Methods: We searched the following electronic databases for relevant studies: PubMed/MEDLINE, EMBASE, Scopus, and Web of Science. Studies were included if they compared the clinical and neonatal outcomes of IVF patients receiving either FT-CDB or DFB transfer with vitrification method. The protocol for this review has been registered in PROSPERO.

Results: A total of seven studies (2057 patients) were included in the analysis. Participants in the FT-CDB group demonstrated significantly higher odds of achieving clinical pregnancy (OR 1.24, 95% CI 1.03-1.49, p = 0.022, I ² = 27%), and live birth (OR 1.31, 95% CI 1.08-1.60, p = 0.007, I ² = 0%) compared to the DFB group. No significant differences were observed in the birth weights of infants between the groups (MD -87.05 g, 95% CI -293.77 to 119.67, p = 0.41, I ² = 83%).

Conclusion: Transferring blastocysts derived from frozen-thawed cleavage embryos is associated with higher odds of clinical pregnancy and live birth compared to frozen-thawed blastocyst transfers.

冷冻解冻卵裂胚胎移植囊胚的生殖结果：系统综述和荟萃分析。

背景：在体外受精（IVF）中，转移冻融囊胚是一种广泛采用的做法。本荟萃分析旨在评估冷冻解冻卵裂胚胎（FT-CDB组）与直接冷冻解冻囊胚（DFB组）移植的生殖结果。方法：检索PubMed/MEDLINE、EMBASE、Scopus、Web of Science等相关电子数据库。如果比较接受FT-CDB或DFB移植与玻璃化方法的IVF患者的临床和新生儿结局，则纳入研究。本次审查的方案已在普洛斯彼罗登记。结果：共纳入7项研究（2057例患者）。与DFB组相比，FT-CDB组的参与者实现临床妊娠（OR 1.24, 95% CI 1.03-1.49, p = 0.022, i2 = 27%）和活产（OR 1.31, 95% CI 1.08-1.60, p = 0.007, i2 = 0%）的几率显著更高。两组婴儿出生体重差异无统计学意义（MD -87.05 g, 95% CI -293.77 ~ 119.67, p = 0.41, i2 = 83%）。结论：冻融卵裂胚移植与冻融胚移植相比，临床妊娠和活产的几率更高。试验注册：PROSPERO号：CRD42024591620。
