Background and Objective: Polymorphonuclear leukocytes (PMNLs) play an important role in the pathogenesis of oxidative ischemia-reperfusion (I/R) damage. There is information that sugammadex inhibits PMNL infiltration into organs and tissues undergoing I/R. Present study aimed to investigate the potential protective effect of sugammadex against I/R-induced ovarian damage in rats and to elucidate its mechanism of action. Materials and Methods: The 24 female albino Wistar-type rats were divided into four groups as follows: Sham operation (SG), ovarian I/R (IRG), sugammadex (4 mg/kg) +ovarian I/R (SIR-4) and sugammadex (8 mg/kg) +ovarian I/R (SIR-8). Sugammadex was administered intraperitoneally. The animals were subjected to 2 hrs of ischemia followed by 2 hrs of reperfusion. Results: Sugammadex significantly inhibited the increase in I/R-induced malondialdehyde and the decrease in total glutathione, superoxide dismutase and catalase levels in ovarian tissue at a dose of 8 mg/kg compared with the dose of 4 mg/kg. Moderate follicular degeneration, vascular congestion, necrosis, oedema and hemorrhage were observed in the sugammadex (4 mg/kg) group, which significantly reduced the increase in I/R-related PMNL infiltration in ovarian tissue. Only mild vascular congestion was observed in the ovarian tissue of the 8 mg/kg sugammadex group, which did not show PMNL infiltration. Conclusion: Histopathological findings show that sugammadex protects ovarian tissue from oxidative and inflammatory injury of the I/R by inhibiting PMNL infiltration. Results also suggest that an 8 mg/kg dose of sugammadex, which completely inhibits PMNL infiltration into ovarian tissue, may be more beneficial than the 4 mg/kg dose in the treatment of I/R-induced ovarian damage.
