| Summary: | Abstract Objective: In vitro, fertilization is the primary treatment method for infertility. Follicular fluid analysis is an approach used to optimize the results of assisted reproductive techniques. Oxidative stress represents the imbalance between the production of reactive oxygen species and their detoxification. Total Antioxidant and Oxidant Status, and Oxidative Stress Index levels are the main oxidative stress markers. This study investigated the effects of oxidative stress markers on infertility etiology, embryo quality, and success of In vitro fertilization. Methods: Before enrolling in the ICSI-ET cycle, participants had their FSH and LH levels assessed on the second day of the cycle. The ovarian degrees of the participants were evaluated by transvaginal ultrasonography. Participants underwent controlled ovarian stimulation using the GnRH antagonist protocol. TV-USG and serial E2 measurements were performed at appropriate intervals to follow follicular development. Follicle sizes, quantity, and endometrial thickness were recorded. Total Antioxidant and Oxidant Status, and Oxidative analyses were conducted using Rel Assay Diagnostics Assay Kits. Results: The average number of total oocytes in the participants was 10.25±6.66, and the average of mature M2 stage oocytes was 6.71±3.72. The average number of fertilized oocytes was 4.65±2.81. Fertilization rates were calculated as approximately 54.75±25.58%. A statistically significant positive correlation was found between embryo quality and serum Total Antioxidant Status levels (p=0.004). Similarly, a significant positive correlation was observed between embryo quality and follicular Total Antioxidant Status values (r = 0.42, p = 0.01). Conclusion: This study concluded that oxidative stress markers affect certain stages of the IVF treatment process. |
