Abstract

Ovarian tissue autografting is a valuable clinical option to help restore fertility in women with cancer. However, many follicles are lost due to ischemia-reperfusion (IR) injury, which depletes follicles after grafting. We aimed to investigate the effect of vitamin C, an antioxidant with anti-apoptotic and anti-inflammatory properties, on improving the structure and function of autografted ovaries in mice. Thirty-six female NMRI mice (4–5 weeks old) were divided into three groups of 12: control (no grafting), autograft + vitamin C (50 mg/kg/day intra- peritoneally), and autograft + saline (100 µl/day/animal, intraperitoneally). After the ovarian autografting and before the start of the experiment, each group was further divided into 7-day and 28-day subgroups. Seven days after ovary autografting, serum levels of malondialdehyde (MDA), total antioxidant capacity (TAC), and in- flammatory factors were measured. On day 28, ovarian histology, DNA fragmentation, and estradiol and pro- gesterone levels were assessed. Results were analyzed using one-way ANOVA and Tukey’s test, with significance set at p<0.05. In the autograft + vitamin C group, there were significant increases in the mean total volume of the ovary, cortex (p<0.05), medulla, number of follicles, and levels of IL-10, progesterone, estradiol, and TAC (p<0.001), compared to the autograft group. Conversely, the rate of apoptosis and serum levels of MDA, IL-6, and TNF- α were notably reduced in the autograft + vitamin C group (p<0.001). These results suggest that vitamin C can significantly enhance the recovery of autografted ovaries through its antioxidant, anti- inflammatory, and anti-apoptotic effects.
