It is normal for the testicles to move on their own. As long as there is no pain or abnormal enlargement, clinical observation is sufficient and no medication is needed. The testicular stimulation may be caused by the contraction of the levator muscle, which pulls the testicle, often due to blunt stimulation, such as light touch stimulation of the groin, scrotal area, inner thigh area, etc., which can induce the contraction of the levator muscle and pull the testicle to cause activity, no treatment is needed, only avoid stimulation factors. Secondly, because the scrotum has a certain contraction and diastolic effect, it will pull the testicles and cause a certain degree of activity, which is also a normal phenomenon. The scrotum will undergo diastolic and contraction movements in response to the external temperature and environmental temperature, which can cause the testicles to contract and diastolic activity in the same direction, which is also a kind of self-physiological regulation and does not require any treatment.
