A sliding testicle is a testicle that is more retractable. When the scrotum is contracted, the testicle may move to the lower groin, and if the scrotum is loose, the testicle may be inside the scrotum. In this case, the specific problem should be analyzed. If you can usually wear relatively loose underwear and the testicles are inside the scrotum, you do not need to do special treatment. If the testicles are usually above the scrotum in the vast majority of cases, that is, in the area of the entrance to the scrotum, some people may shrink to the inguinal canal, in this case, it is recommended to perform testicular descent. The testicles are inside the scrotum, which is 1.5-2°C lower than the normal body temperature, so that the testicles can perform their normal spermatogenic function.
