In conclusion, there may be an imbalance in the thiol-redox system and increased levels of inflammatory cytokines in the intrafollicular microenvironment of infertile patients with endometriosis, which may affect the qualities of the oocyte and embryo. |

The study included 65 patients receiving IVF: 31 patients with endometriosis vs 34 patients without endometriosis. Follicular fluid (FF) was obtained from a single-dominant follicle during oocyte retrieval and stored at -70 degrees C. Malondialdehyde, superoxide dismutase, glutathione (GSH), glutathione peroxidase 3 (GPX3), thioredoxin (TRX), TRX-binding protein 2 (TBP2), and peroxiredoxin-4 levels were measured in the FF samples by ELISAs as biomarkers of oxidative stress. The inflammatory cytokines interleukin 1 beta (IL1beta), IL6, IL8, and tumor-necrosis factor alpha (TNFalpha) were also measured by ELISAs. GSH levels were significantly lower in the endometriosis group compared with the controls. TBP2 levels were significantly higher in the endometriosis group. IL6, IL8, and TNFalpha levels were significantly higher in the endometriosis group. The levels of all of the inflammatory cytokines positively correlated with the levels of TRX. GSH levels positively correlated with the number of high-quality embryos. GPX3 and TRX levels negatively correlated with the percentage of mature oocytes. TNFalpha levels negatively correlated with the cumulative embryo score per embryo. Logistic regression analysis revealed that the number of high-quality embryos was an independent factor predicting clinical pregnancy. In conclusion, there may be an imbalance in the thiol-redox system and increased levels of inflammatory cytokines in the intrafollicular microenvironment of infertile patients with endometriosis, which may affect the qualities of the oocyte and embryo.
