Histological assessment for investigation of dose-dependent ovarian toxicity of cyclophosphamide in the rat

Differential follicle counts revealed that CPA-induced ovarian toxicity is exhibited in structural feature of the ovary, particularly in destruction of graaf and preantral follicles in a dose-dependent manner so that the highest decrease in all type of studied follicles caused by 50 mg/kg of CPA and is suggested as the best concentration for ovotoxicity induction. These findings give insight into ovarian response to structural disruption of folliculogenesis.
