Abstract

Background/Aims: To investigate the effectiveness of controlled reperfusion (CR) on ovarian tissue malondialdehyde, total glutathione and 8-hydroxyguanine levels and infertility rates in a rat model of induced ischemia-reperfusion (I/R) injury with unilateral oophorectomy. Methods: A total of 135 adult female albino Wistar rats were divided into 9 groups (n = 15 for each group): unilateral ovariectomy + ovarian I/R (OIR), unilateral ovariectomy alone (OEG), a sham operation group (SG), and unilateral ovariectomy + CR performed at different intervals (the clips were released 10 times for 10, 8, 6, 4, 2 or 1 s and closed again 10 times for 10, 8, 6, 4, 2 or 1 s; OCR-1-6, respectively). Five rats from each group were sacrificed, and their ovaries were removed. Results: Higher ovarian tissue malondialdehyde and 8-hydroxyguanine levels and lower ovarian tissue total glutathione levels were found in the OIR group compared with the SG, OEG and OCR-4-6 groups. The number of rats giving birth during the study period was found to be similar among the SG (n = 8), OEG (n = 8) and OCR-6 (n = 7) groups. Conclusion: These results suggest that sterility and ovarian oxidative stress caused by I/R injury decreases in parallel to the shortening of CR duration. (C) 2015 S. Karger AG, Basel
