Abstract

PURPOSE

The aim of this study was to evaluate the role of interleukin 6 in embryo development in the in vitro fertilization cycles.

METHODS

This was a retrospective cohort study. One hundred and three women undergoing in vitro fertilization and embryo transfer due to a tubal factor were included in the study. The follicular fluid IL-6 levels on oocyte retrieval day from each patient were determined by ELISA. The relationships between follicular fluid IL-6 levels and IVF cycle parameters were investigated.

RESULTS

The levels of follicular fluid IL-6 were not affected by the use of drugs for superovulation or by estrogen. In addition, follicular fluid IL-6 levels did not affect the number of oocytes retrieved or the MII oocyte rate. High levels of follicular fluid IL-6 correlated with a significant increase in the rates of clinical pregnancy. Follicular fluid IL-6 levels did not affect the cell number or the blastomere symmetry of day 3 embryos, but it did significantly reduce the embryo fragmentation rate.

CONCLUSIONS

High levels of follicular fluid IL-6 improved the rates of clinical pregnancy and reduce embryo fragmentation.

摘要

目的

本研究旨在评估白细胞介素 6 在体外受精周期中胚胎发育中的作用。

方法

这是一项回顾性队列研究。本研究纳入了 103 名因输卵管因素接受体外受精和胚胎移植的女性。通过 ELISA 法测定每位患者取卵日卵泡液中白细胞介素 6 的水平。研究了卵泡液 IL-6 水平与 IVF 周期参数之间的关系。

结果

卵泡液 IL-6 水平不受超排卵药物和雌激素的影响。此外,卵泡液 IL-6 水平并不影响获卵数或 MII 卵率。高卵泡液 IL-6 水平与临床妊娠率显著增加相关。卵泡液 IL-6 水平并不影响第 3 天胚胎的细胞数或卵裂球对称性,但显著降低胚胎碎片率。

结论

高卵泡液 IL-6 水平可提高临床妊娠率,降低胚胎碎片率。
