Why do some men have scrotum? It's tight and some are loose.

Normal people's testicles vary in size on both sides, but the difference is generally not too big. If the size of both testicles was basically similar in the past, and one testicle suddenly increased significantly in the near future, you should go to the hospital for examination in time. If one testicle is swollen, accompanied by fever and local pain, it may be epididymitis or orchitis. If testicular enlargement is not accompanied by any symptoms, it is necessary to consider whether there is a possibility of testicular tumor and check it in time. We must not be careless. In normal men, some people's testicles vary in size from small to large, and the difference is sometimes obvious, which is mostly caused by congenital diseases, such as congenital testicular dysplasia on one side, but this situation is generally rare. In addition, trauma causes testicular bleeding and hematoma, which leads to testicular blood supply disorder atrophy, which can cause the difference of testicular size between the two sides. Mumps virus can also cause testicular atrophy on one side. Of course, there are many reasons for the unequal testicular size on both sides, but we should be careful not to think that other diseases of scrotum are also the reasons for the unequal testicular size, and we should distinguish the reasons to avoid misdiagnosis. In short, if the scrotum changes for any reason, one side is obviously larger than the other side, you should go to the hospital in time ... thank you.
