Why is it that one of my child's testicles is larger than the other?

We all know that the important function of testicles is closely related to male fertility, but many children have testicular abnormalities, such as one testicle is large and the other is relatively small. Once this happens, parents are bound to be very worried, fearing that it will have an immeasurable impact on their children. So, why does one child have one testicle, larger than the other? Let’s take a closer look at it.

Some people's testicles are different in size from childhood, and the difference is sometimes very obvious. This is mostly caused by congenital diseases. For example, congenital unilateral testicular hypoplasia may manifest as a very small and soft testicle on one side, like a juvenile testicle, while the contralateral testicle may have compensatory enlargement and be larger than that of a normal person. Therefore, the testicles on both sides are different in size, but this situation is generally rare. In addition, trauma can also cause a difference in the size of the testicles on both sides. For example, trauma can cause intratesticular bleeding and hematoma, which results in testicular blood supply obstruction and testicular atrophy, so the affected side is smaller than the contralateral testicle.

The mumps virus can damage the epithelial cells of the seminiferous tubules of the testicles, causing atrophy of one side of the testicle. Of course, there are many reasons for the unequal testicle sizes on both sides, but care should be taken not to consider other diseases in the scrotum such as hydrocele, hernia, etc. as the cause of testicle size. The causes should be distinguished to avoid misdiagnosis. In short, if one side of the scrotum is significantly larger than the other due to any reason, it should be checked promptly. It is recommended to go to the urology department of a regular hospital for examination and treatment.

If there is a difference in testicular size, it is usually caused by testicular hydrocele or hernia and other factors. Guidance: Testicular hydrocele in newborn babies often disappears on its own before the age of two, so there is no need to rush for treatment. If it does not disappear after two years of age. Then perform puncture and fluid extraction. Most cases do not recur after aspiration.

The above is an introduction to what happens when a child has one testicle, one larger than the other. I hope it will be helpful to parents. There are many factors that lead to different sizes of testicles in children. When this situation is discovered, it is best to conduct a comprehensive observation. If it persists, you should go to a regular hospital for diagnosis and treatment in time to avoid more serious effects on the child.
