Is it normal for a man's testicles to be big and small?

Normally, the male testicles are not the same size. The right testicle is slightly larger than the left testicle, but the difference between the two is not too big. If the male testicles are obviously larger and smaller, it is abnormal. One side of the testicle may be enlarged due to orchitis, testicular tuberculosis or testicular tumor; while the other side of the testicle may be small due to testicular atrophy due to varicocele. No matter what kind of reason will affect the normal testicular function of men, it will affect the normal fertility and sexual ability of men. Therefore, it is necessary to go to the hospital as soon as possible to check clearly what is caused by the cause, so as to determine what kind of treatment measures to take.
