High testicles on one side and low testicles on the other side may be a normal physiological phenomenon, or it may be caused by varicocele, testicular torsion, testicular inflammation and other reasons. 1. Under normal circumstances, male testicles will not be at the same level, there will be high on one side and low on the other, but the difference between the two will not be particularly obvious, and there are no other abnormal symptoms. 2. Varicocele will cause the male scrotum to droop and the accompanying testicles will also drop, so the left and right testicles will not be equal, the left testicle may be higher and the right testicle lower. 3. When one side of the testicle is twisted, the position will be higher and the other side will be lower. 4. When the testicle is inflamed, it will be enlarged and the testicle will be positioned lower than the normal side, and it will also look like the testicle is high on one side and low on the other. There may be other reasons for the testicles to be high on one side and low on the other side. If the testicles appear to be high on one side and low on the other side, you can observe whether there is pain in the testicles and whether you can touch the varicose blood vessels with your hands, and if there is any abnormality, you have to consult the doctor in time.
