Postoperative sexual dysfunction in male rectal cancer is a painful complication. In recent years, this complication has been further recognized. This article reports on the pathogenesis of the complication, incidence and type of operation. The relationship between age and prevention methods is summarized as follows. Mechanism of occurrence. Physiological male sexual function depends on the complete autonomic nervous system. The sympathetic nerve fibers that control the pelvic reproductive organs arise from T_(12)-T2 in the retroperitoneal flank aorta. Decreases, forming a sub-abdominal plexus near the bifurcation of the aorta, dividing it into two trunks at approximately the level of the fistula, and descending into the pelvic cavity along the side of the basin, known as the lower abdominal nerve.
