Abstract

BACKGROUND

Today, the thickness of the endometrium as a key factor plays an important role in pregnancy outcomes of infertile patients. Based on this, it has been shown that endometrial compaction affects fertility success in patients. In this study, the impact of endometrial compaction on pregnancy outcomes (assisted reproductive technology) has been evaluated.

MATERIAL AND METHODS

This prospective cohort study included 253 patients undergoing embryo transfer, who referred to the infertility center of Shariati Hospital in Tehran during 2021-2022. They were examined from the point of relationship between endometrial thickness changes and fertility rate in frozen embryo transfer and fresh cycles. After preparing the endometrium, the thickness was evaluated using ultrasound.

RESULT

The results showed that the percentage of chemical and clinical pregnancy in the compact group was higher compared to the non-compact one, which was statistically significant ( < 0.05). The rate of pregnancy in four groups of 5, 10, 15, and %20 compaction was 77(30.4%), 49(19.4%), 28(11.1%), and 14(5.5%), respectively.

CONCLUSION

Finally, endometrial compaction can be associated with an increase in chemical and clinical pregnancy rate in infertile patients. In addition, secondary thickness has predictive value for clinical pregnancy.

摘要

背景

如今，子宫内膜厚度作为一个关键因素，在不孕患者的妊娠结局中起着重要作用。基于此，研究表明子宫内膜致密化会影响患者的生育成功率。在本研究中，评估了子宫内膜致密化对妊娠结局（辅助生殖技术）的影响。

材料与方法

这项前瞻性队列研究纳入了253例接受胚胎移植的患者，这些患者于2021年至2022年期间前往德黑兰沙里亚蒂医院不孕中心就诊。从冷冻胚胎移植和新鲜周期中子宫内膜厚度变化与生育率之间的关系角度对他们进行了检查。在准备好子宫内膜后，使用超声评估其厚度。

结果

结果显示，致密组的生化妊娠和临床妊娠百分比高于非致密组，具有统计学意义（<0.05）。5%、10%、15%和20%致密化的四组妊娠率分别为77（30.4%）、49（19.4%）、28（11.1%）和14（�.5%）。

结论

最后，子宫内膜致密化可能与不孕患者生化妊娠和临床妊娠率的增加有关。此外，二次厚度对临床妊娠具有预测价值。
