Can Coenzyme Q10 supplementation protect the ovarian reserve against oxidative damage?

Abstract：

PURPOSE:We investigated antioxidant effects of CoQ10 supplementation on the prevention of OS-induced ovarian damage and to evaluate the protective effect of such supplementation against OS-related DNA damage. METHODS:Twenty-four adult female Sprague-Dawley rats were randomly divided into three groups (8 rats per group): group 1 (control): saline, ip, and orally; group 2 (cisplatin group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days; and group 3 (cisplatin + CoQ10 group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days, and 24 h before cisplatin, 150 mg/kg/day orally in 1 mL of saline daily for 14 days. Serum concentrations of anti-Mullerian hormone (AMH), number of AMH-positive follicles, the assessment of the intensity of 8'OHdG immunoreactivity, the primordial, antral and atretic follicle counts in the ovary were assessed. RESULT(S):The mean serum AMH concentrations were 1.3 ± 0.19, 0.16 ± 0.03, and 0.27 ± 0.20 ng/mL in groups 1, 2, and 3, respectively (p < 0.01). Serum AMH levels were significantly higher in group 1 compared to groups 2 and 3 (p < 0.01 and p = 0.01, respectively). There was a statistically significant difference in AMH-positive follicle count between the groups (p < 0.01). Group 1 showed higher numbers of AMH-positive granulosa cells compared to group 2 (p = 0.01). A significant difference was found in the primordial, the atretic, and antral follicle counts between the three groups (p < 0.01, p < 0.01, and p < 0.01, respectively). The atretic follicle count was significantly lower in the cisplatin plus CoQ10 group compared to the cisplatin group (p < 0.01). The antral follicle counts were significantly higher in the cisplatin plus CoQ10 group compared with the cisplatin group (p < 0.01). There was a statistically significant difference in the intensity of staining of the follicles that were positive for anti-8'OHdG between the groups (p = 0.02). Group 1 showed a significant lower intensity of staining of the follicles positive for anti-8'OHdG compared with group 2 (p = 0.03). CONCLUSION(S):CoQ10 supplementation may protect ovarian reserve by counteracting both mitochondrial ovarian ageing and physiological programmed ovarian ageing although the certain effect of OS in female infertility is not clearly known.
