Ovarian cancer is the sixth most common malignancy among women in developed countries and the fifth leading cause of cancer-related death, representing a complex disease associated with poor survival rates.24 The combination chemotherapy of Paclitaxel (PTX) and Carboplatin (CARB) is considered the first-line treatment regimen for ovarian cancer.25 Both agents play distinct roles in inhibiting the growth of ovarian cancer through different mechanisms,26 and they are known to exert a synergistic anti-tumor effect by activating separate apoptotic signaling pathways, thereby potentially reducing drug resistance.25 The gonadotoxic effects of platinum-based chemotherapeutic agents have been demonstrated in numerous studies, both histopathologically and in terms of follicular development.27-29 In the present study, CARB administration led to significant histopathological damage in ovarian tissue, including follicular degeneration, prominent stromal edema, congestion, hemorrhage, inflammation, and fibrosis, particularly in the medullary region
