Aim: This study focused on the anti-oxidant and anti-apoptotic effects of CoQ10 in ovaries exposed to pelvic radiation. Methods: Thirty-two female rats were randomly assigned into four groups. Group I (control group), Group II: Only 2 Gy pelvic x-ray irradiation (IR) was administered as a single fractioned dose. Group III: 30 mg/kg CoQ10 was administered by oral gavage +2 Gy pelvic IR. Group IV: 150 mg/kg CoQ10 was administered by oral gavage +2 Gy pelvic IR. CoQ10 treatment was started 7 days before pelvic IR and completed 7 days later. The rats in Group III and IV were treated with CoQ10 for a total of 14 days. Results: Histopathological analysis showed severe damage to the ovarian tissue in the radiation group, while both doses of CoQ10 showed normal histological structure. Likewise, while there was a high level of staining in the IR group for necrosis and apoptosis, the CoQ10 treated ones were like the control group. Tissue Malondialdehyde (MDA) levels were like the control group in the low-dose CoQ10 group, while the MDA levels of the high dose CoQ10 group were similar to the radiation group. Conclusion: Usage of low-dose CoQ10 has a radioprotective effect on radiation-induced ovarian damage. Although the use of high doses is morphologically radioprotective, no antioxidative effect was observed in the biochemical evaluation.
