Male infertility is one of the most common diseases in andrology. Studies show that male infertility is significantly correlated with the incidence and mortality of tumors, especially malignant tumors in the genitourinary system, such as testis cancer and prostate cancer. The relationship of male infertility with genitourinary system tumors involves various aspects, mainly including changes in chromosome mutations, epigenetic marks, hormonal imbalance, and congenital deformity. Besides, some chronic diseases are shown to be significantly associated with male infertility, and semen quality or fertility status may be biomarkers of the overall health of males. In-depth studies of the correlation between male infertility and these factors are very important for an insight into the pathogenesis and prevention of the related diseases.
