The Impact of Noncavity-Distorting Intramural Fibroids on the Efficacy of In Vitro Fertilization-Embryo Transfer: An Updated Meta-Analysis

الملخص EN

Aim.

To address the impact of noncavity-distorting intramural fibroids on the efficacy of in vitro fertilization-embryo transfer (IVF-ET) outcomes.

Methods.

The PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure were searched systematically.

A meta-analysis was performed based on comparative or cohort studies that explored the impact of noncavity-distorting intramural fibroids on the efficacy of IVF-ET treatment.

The IVE-ET outcomes of study group (women with noncavity-distorting intramural fibroids) and control group (women without fibroids) were compared, including live birth rate (LBR), clinical pregnancy rate (cPR), implantation rate (IR) , miscarriage rate (MR), and ectopic pregnancy rate (ePR).

Results.

A total of 28 studies involving 9189 IVF cycles were included.

Our meta-analysis showed a significant reduction of LBR in the study group compared to control group (RR = 0.82, 95% CI: 0.73-0.92, and P = 0.005).

In addition, it indicated that study group had a significant reduction in cPR (RR = 0.86, 95% CI: 0.80-0.93, P = 0.0001) and IR (RR = 0.90, 95% CI: 0813-1.00, P = 0.04) and have a significantly increase in MR (RR = 1.27, 95% CI: 1.08-1.50, and P = 0.004) compared with control group.

Conclusions.

The present evidence suggests that noncavity-distorting intramural fibroids would significantly reduce the IR, cRP, and LBR and significantly increase the MR after IVF treatment, but it would not significantly increase the ePR.
