Kneading the testicles is harmful and will not have any benefits, as follows: 1, the testicles themselves like a cool environment, because the testicles are in the scrotum, through the scrotum of the skin contraction changes and regulate the body temperature, lower than the body temperature of about 1-2 ℃, if repeatedly kneading the testicles can cause local temperature abnormalities and cause abnormal changes in the sperm function, the quality of semen decline, so often knead the testicles, especially Therefore, frequent kneading of the testicles, especially in young unmarried men, may cause a decrease in semen quality; 2, the testicular envelope is rich in nerves, which can produce a special pain when kneading, and sometimes the kneading can even produce transient spasmodic pain, and serious patients may even experience neurogenic shock and other reactions; 3, repeated kneading of the testicles may cause a higher chance of testicular torsion, as the testicles themselves are fixed by the spermatic cord in the scrotum and are in a relatively large range of activity. The testicle is fixed in the scrotum by the spermatic cord and is in a relatively large range of motion, so kneading may cause ischemia or even necrosis of the testicle when the testicle is rotated by the spermatic cord during the kneading process, so it is contraindicated to knead the testicle.
