Varicoceles can gradually worsen, and varicoceles are usually caused by anatomical variations of the blood vessels themselves, for example, varicoceles are more likely to occur if there are too few valves, or if the pressure in the left deep vein is too high, or if there is pressure from the sigmoid colon, or if there are chronic compression factors such as prolonged abdominal exertion, all of which can cause varicoceles, and the degree of varicoceles will increase if these factors are not removed. If mild varicocele becomes moderate or severe, it is recommended to visit the hospital early and give relevant interventions if necessary. Generally, if moderate or severe varicocele is found to be combined with abnormal semen quality, early surgery is recommended to avoid the risk of infertility. Also, prolonged varicocele is an important factor in testicular atrophy, so early treatment is needed. For secondary varicocele, treatment is needed for the primary lesion, such as retroperitoneal examination for retroperitoneal related lesions in order to recover early, otherwise the cause will gradually increase the degree of varicocele if the trigger is not removed.
