The association between endometrial polyps, chronic endometritis, and IVF outcomes.

OBJECTIVE

Endometrial polyps (EPs) are one of the most common pathologies detected during the examination of the uterine cavity of infertile women. We aimed to demonstrate the relationship between EPs, chronic endometritis (CE) and in vitro fertilization (IVF) outcomes.

PATIENTS AND

METHODS

This retrospective study was performed on 394 hysteroscopically examined infertility cases. We performed polyp resections (PR) and extensive biopsies of the endometrium to demonstrate the association with clinical pregnancy (CP) by IVF. We performed statistical analysis to compare these associations.

RESULTS

The incidence of CE was twice as high in the presence of EPs as in the absence of EPs. The associations between EPs and PR were found to be significant for positive CP outcomes. A significant difference in IVF outcome was found between the group with EPs and the group without EPs. All these associations were statistically significant (p < 0.05).

CONCLUSIONS

We found a frequent association between EPs and CE. The pregnancy rate obtained after IVF was negatively affected by the presence of EPs. Treatment of these pathologies improved IVF outcomes.
