This study was aimed at investigating the effects of melatonin, oxytetracycline and N-acetylcysteine on the ovarian follicle reserves and surface epithelium in autologous intraperitoneal ovarian transplantation in rats. Thirty adult female Wistar Albino were selected and randomly divided into six groups (n = 5). Group 1, which was the control group, only had their abdomens opened and closed while Group 2 underwent ovarian transplantation. Group 3, 4, 5 and 6 received 20 mu g/kg/IM melatonin, 10 mg/kg/IM oxytetracycline, 150 mg/kg/IP N-Asetil sistein (NAC) and 1% ethanol respectively 15 min before the ovarian transplantation. Vaginal cytology was performed to monitor the estrus phase and the follicle reserve and changes in the surface epithelium were histopathologically evaluated during the preparations. Moreover, cellular apoptosis in tissues was evaluated with immunofluorescence staining of Bcl-2 and Bax. The Bax/Bcl-2 ratio was then calculated as the mean fluorescence intensity (MFI) of Bax and Bcl-2 MFI. Dysplastic change was found only significantly higher in the transplantation group (G2) (p < 0.01). Histopathologically, it was found that the follicle reserve was preserved significantly in the oxytetracycline and melatonin treated group (G3, G4) (p < 0.01). It was also observed that the oxytetracycline treated group (G4) were able to show better preventive effects against dysplastic changes of the surface epithelium. Moreover, the melatonin treated group depicted a low Bax/Bcl-2 ratio compared to the group that only underwent transplantation (G2) (p < 0.01). This study indicated that oxytetracycline and melatonin might be more effective than N-acetylcysteine in protecting against oxidative stress during ovarian transplantation. (C) 2022 Elsevier Inc.
