Why is the right testicle bigger than the left?

The right side of the testicle is larger than the left may be caused by physiological differences, varicocele, orchitis, epididymal cyst, testicular hydrocele, etc. Interventions can be made through physical examination, ultrasound examination, drug treatment, surgical treatment, etc.

1. Physiological differences

Slight differences in the size of the testicles on both sides are normal. Usually the right testicle is slightly larger than the left, which is related to local blood circulation, development process and other factors. If there is no pain, swelling or other discomfort, no special treatment is required, just regular observation. You should avoid sitting for long periods of time or wearing tight pants to reduce local compression.

2. Varicocele

Varicocele is more common on the left side, but when it occurs on the right side, it can cause testicular enlargement, which may be related to venous valve insufficiency or increased abdominal pressure, and is often accompanied by a feeling of scrotal swelling. Diagnosis requires scrotal ultrasound examination. Mild cases can be relieved by wearing special support pants. Severe cases require high spermatic vein ligation. Drugs such as Maizhiling tablets and diosmin tablets can be used to improve venous return.

3. Orchitis

Bacterial or viral infection may cause orchitis, which manifests as redness, swelling, heat and pain in one side of the testicle, which may be accompanied by fever. Common pathogens include Escherichia coli, mumps virus, etc. Treatment requires the use of anti-infective drugs such as ceftriaxone sodium for injection and acyclovir tablets based on the cause, combined with bed rest and scrotal elevation. Sexual life should be prohibited during the acute phase.

4. Epididymal cyst

Cystic masses formed in the head of the epididymis may cause local enlargement of the testicles, which may appear as smooth masses upon palpation. Ultrasound examination can confirm the diagnosis. Smaller cysts do not require treatment. If the size exceeds 3 cm or causes pain, epididymal cyst removal may be considered. It is necessary to avoid strenuous exercise on a daily basis that may cause the cyst to rupture.

5. Testicular hydrocele

When the sheath is not closed and fluid accumulates, it manifests as painless swelling of the scrotum and a positive light transmission test. Primary effusions in infants and young children may be absorbed by themselves, and if the effusion continues to increase in adults, testicular tunica inversion surgery is required. The wound should be kept dry after surgery and weight-bearing activities should be avoided for two weeks.

It is recommended to wear loose cotton underwear to reduce friction and avoid long-term riding or high temperature environments. If you find changes in testicular hardness, a significant increase in volume within a short period of time, or abnormal urination, you should seek medical attention promptly to check for possible tumors. Daily self-examination can be used to compare the morphological changes of both sides of the testicles on a daily basis. During the examination, pay attention to the difference between the standing position and the supine position.
