A 5-year-old boy has one testicle, one larger than the other?

Generally, the sizes of the testicles on both sides of a normal male are not exactly the same, one is larger and the other is smaller. Even people of the same age group have different testicle sizes. If the size difference between the two sides is not particularly large, it is actually a normal phenomenon. If you suddenly find that one side is obviously larger, you need to pay attention. Generally, if the testicles of a 5-year-old boy are of different sizes, it is likely that he has hydrocele and must be treated in time.

The size is within the normal range and will not affect fertility

If the testicles are too small, the spermatogenesis function of the testicles may be impaired, with low sperm count or no sperm, which may lead to loss of fertility. The testicles of normal people are not of equal size on both sides. According to statistics, the right side is slightly larger than the left side. As long as the size of both sides is within the normal range, it will not affect fertility.

Some people have one testicle larger than the other since childhood. One testicle is very small and soft, while the other side has a very obvious difference due to compensatory hyperplasia. This is congenital unilateral testicular dysplasia. Trauma to one testicle can also cause one testicle to be larger than the other. Trauma causes bleeding and hematoma in the testicle, which results in insufficient blood supply to the testicle, which gradually atrophies and becomes significantly smaller than the other side. Some people suffer from mumps and orchitis when they are young. The virus destroys the epithelial cells of the seminiferous tubules in the testicle, causing one testicle to atrophy, resulting in one testicle larger than the other.

If the two testicles have always been symmetrical in the past, and one side suddenly becomes significantly larger, accompanied by fever and local pain, it may be orchitis or epididymitis. Testicular eccentricity is mostly caused by diseases, such as testicular hydrocele, testicular tumor, epididymal tuberculosis, etc. If these diseases are not treated in time, they will also cause low sperm and semen quality and affect fertility.

In short, if the size of the two testicles is not much different and both are within the normal range, it will not affect fertility. If one side is small and the other side is normal, fertility may be low, but fertility is still possible. When one side is too large or too small, it is necessary to consider whether there is a disease and go to the hospital's urology department for examination and treatment in time.

Learn to do a self-examination of the testicles. If you feel pain when touching the testicles, you should seek medical attention immediately.

Men can do self-testicular examination to detect any disease in time.

When doing a self-examination of the testicles, the first thing to pay attention to is the size of the testicles. Testicle size is related to age. For children under the age of 12, the testicles are in a relatively quiescent period, and the general volume is 1 to 4 ml. After the age of 12, boys enter puberty and the testicle volume increases rapidly. The testicle volume of adult men is 16 to 25 ml, with an average of 19.8 ml. After the age of 60, they enter the aging stage, and the testicle volume gradually shrinks. After the age of 70, the testicle volume shrinks to less than 16 ml. If the testicle volume of both sides of an adult male is less than 10 ml, it is a small testicle, which may cause sexual dysfunction or male infertility.

Palpate and examine the testicles. The normal state of the testicles should be smooth, full, non-tender, and clearly separated from the epididymis. If the testicles are found to be enlarged in a short period of time and are not tender, it may be testicular cancer; if the testicles are painful when touched, it indicates that the testicles are inflamed; if the scrotum is enlarged and the testicles and epididymis cannot be felt, it may be hydrocele, that is, fluid accumulation in the scrotum; if the epididymis is painful and swollen, it indicates that the epididymis is diseased.

In addition, if the scrotum and testicles feel swollen or painful, and the pain worsens when standing for a long time or walking for a long distance; and the symptoms are relieved or disappear when lying flat, it may be varicocele. Typical varicocele can see twisted and dilated veins under the skin of the scrotum; or when you touch it with your hands, you can feel the dilated blood vessels in a vermiform mass. Primary varicocele can shrink or disappear after lying flat. If the symptoms still do not improve when lying flat, it may be compression caused by tumors or other lesions. Once the above symptoms appear, it is best to go to the hospital for diagnosis and treatment as soon as possible.
