The effect of localization and histological verification of endometrial polyps on infertility

Our purpose is to investigate if transcervical resection of endometrial polyps improves the fertility in ovulatory infertile women, and whether polyp histology, intrauterine location, and the technique of polypectomy have any influence on the pregnancy rates.

In this retrospective study, clinical data of 87 ovulatory infertile women who underwent hysteroscopy and polypectomy, and their 12-month follow-up have been analyzed. Subgroups according to the method of polyp removal (resectoscope or curettage), the polyp localization (utero-tubal, anterior, posterior, lateral, multiple) and the histological result were interpreted.

Mean age of patients was 33.99 ± 4.24 years. There were no differences in the BMI and basal FSH levels between the subgroups. Pregnancy was recorded in 30 (34.5%) within the next 12 months without any difference between the subgroups of polypectomy method applied. Posterior wall polyp resection increased the pregnancy chance (OR 5.02), but no other differences were observed in 1-year pregnancy rates to other localizations. Removal of polyps which had normal endometrial histology had lower pregnancy rates as compared to that of polyps with hyperplasia or endometrial polyp histology results (OR 0.25).

Polypectomy improved the conception rate in the subsequent year regardless of the intrauterine localization and the method of its surgical removal. Therefore, we can conclude that polypectomy should be considered in infertile women.
