Worldwide, malignant tumours have become one of the most common causes of death in men. With the continuous progress of comprehensive oncological treatment, the cure rate and the survival rate of malignant tumours have been increasing, and the survival cycle has been prolonged, so the issue of fertility preservation in male malignant tumour patients has received widespread attention. In this review, researchers will discuss the real-world research progress related to fertility preservation in male malignant tumour patients, with a view to provide some reference basis for clinical decision-making.
