If a large testicle is within the physiological range, and both testicles are above 12ml with a difference of no more than 20%, it usually does not need any treatment and can be treated as a normal condition. If it is caused by syringomyelia, surgical treatment can be chosen to excise and flip the syringomyelia and suture it; for it is caused by epididymitis or testicular inflammation, it needs to be treated symptomatically with antibacterial or antiviral drugs, and at the same time strengthen the rest; if it belongs to the growth of testicular mass, it needs to be examined in the regular hospital by the professional doctor as soon as possible to determine whether the mass is a tumor or not, so as to carry out the surgical treatment further.
