Chemotherapy, the cornerstone of cancer treatment, often leads to unintended consequences, including significant changes in ovarian morphology. The ovaries, crucial female reproductive organs, undergo profound structural alterations after chemotherapy, impacting fertility, hormonal balance, and overall reproductive health. This dissertation comprehensively analyzes the morphological changes induced by chemotherapy in the ovary, elucidates their underlying mechanisms, and explores implications for fertility preservation strategies. Through a systematic review of existing literature, combined with clinical observations and experimental data, this study aims to provide an in-depth understanding of the effects of chemotherapy on ovarian morphology and its broader implications for women's health. By shedding light on the complex interaction between cancer treatment and fertility, this dissertation aims to inform clinical practice, guide patient counseling, and stimulate further research in the field of oncofertility.
