... ке некрозе-α (TNF-α) у испирку материце и серуму код инфертилних жена SUMMARY Introduction/Objective The aim of this paper is to present changes of tumour necrosis factor-α (TNF-α) levels in uterine flushings and serum of infertile female patients before and after hysteroscopic polypectomy. Methods A total of 82 infertile female patients were included in the study. The patients were divided into two groups. The first group was the experimental group and comprised 56 infertile women with endometrial polyps, whereas the second group was the control group of 26 infertile women who were not diagnosed with endometrial polyps. Results The results of this research primarily suggest that TNF-α concentration obtained from uterine flushings and serum of infertile patients diagnosed with endometrial polyps differed before and after a surgical procedure. In the control group of patients, there was no significant difference observed regarding TNF-α concentrations in serum and uterine flushings of women without endometrial polyps. A comparison between these two groups revealed differences in TNF-α concentrations both in venous blood and uterine flushings. These differences were considered statistically significant. Conclusion Endometrial polyps are one of the causes of higher TNF-α levels both in uterine flushings and serum.
