Is it normal to have one testicle that is obviously larger than the other?

The testicle is the male reproductive organ, located below the male penis. Generally, there is a left and right testicle. One testicle is larger than the other. It is very common. Whether the left testicle hurts or the right testicle is swollen, you need to pay attention to it. The normality of the testicle will directly affect personal fertility, especially when one testicle is significantly larger than the other, which is usually a manifestation of testicular abnormality.

Is it normal to have one testicle larger than the other?

Some people's testicles are small, one side is large and the other side is small, the difference is very obvious, this is mostly caused by congenital diseases. For example, congenital unilateral testicular hypoplasia is manifested as one side of the testicle is very small and thick, while the other side is compensatory hyperplasia, which is larger than that of ordinary people, resulting in one side of the testicle being large and the other side being small, but this situation is relatively rare.

Traumatic injury to one side of the testicle can also cause one side of the testicle to be larger than the other side. Traumatic injury causes bleeding and hematoma in the testicle, which results in insufficient blood supply to the testicle, causing it to gradually atrophy and become significantly smaller than the other side.

Mumps virus can damage the epithelial cells of the seminiferous tubules in the testicles, which is one of the important reasons why one side of the testicle is larger than the other, and eventually causes testicular atrophy.

What is the normal size of testicles?

Generally speaking, the size of the testicles on both sides of normal men is not exactly the same. According to statistics, the right testicle is slightly larger than the left. If the length, width and thickness of the testicle are used for calculation, the right side is 3.38×2.37×. 78 (cm) on average, and the left side is 3.30×2.27×. 71 (cm) on average. Even people of the same age group have very different testicle sizes.

Normal testicles are not equal in size, but the difference is not too big. If the testicles on both sides have always been symmetrical in the past, and one of them suddenly becomes significantly larger, you should pay attention. If the testicles are enlarged and accompanied by fever and local pain, it may be epidemiitis or orchitis. If the testicles are enlarged without any symptoms, the possibility of testicular tumor is greater. You should see a male specialist for further examination as soon as possible and do not take it lightly.

Testicular abnormalities

Abnormal testicular position: Syndrome is when the two testicles merge into one, or are mistaken for cryptic testis or monotestis, often accompanied by other serious congenital malformations. Very few patients develop into adults. Cryptorchidism is relatively common. Cryptorchidism refers to the testicles staying in any abnormal position during the descent process, such as the waist, abdomen, inguinal canal or other places, collectively known as cryptic testis. Cryptorchidism can only be effectively treated through surgery.

Abnormal testicular size: Abnormal testicular size includes congenital testicular dysplasia, testicular atrophy, etc. Testicular dysplasia may occur due to blood supply disorders during the embryonic period or spermatic cord torsion during testicular descent. Testicular dysplasia may also occur during sexual immaturity and hypopituitarism.
