What causes one side of the testicle to swell?

In daily life, the testicle is the most important part of the male body, and enlargement of one side of the testicle is also a very common situation. This may be a manifestation of a disease. There are many reasons for the enlargement of one side of the testicle. Generally, it may be due to testicular cysts or symptoms caused by orchitis, which are very harmful to the body and need to be treated in time.

What are the causes of testicular enlargement?

Swelling on one side of the testicle may be caused by orchitis or a testicular cyst.

harm

Generally, there are three causes of orchitis in clinical practice: inflammation, cysts, and trauma. Most cases are caused by testicular or genital inflammation. The main hazards are:

1. Testicular inflammation may spread to the urinary tract, glans penis, and prostate gland, causing damage to the entire reproductive environment, abnormal urination, wet and itchy testicles, and other prostate symptoms.

2. Inflammation stimulates the penis, increasing its sensitivity, causing premature ejaculation and even affecting a person's erectile ability, leading to sexual dysfunction.

3. The testicles are directly related to sperm quality. Long-term testicular pain will lead to a sharp decline in sperm quality, leading to infertility.

Causes

Bacterial infection

Unilateral testicular swelling and congestion is mostly caused by descending infection from the prostate. Long-term placement of a urinary catheter, urethroscopy, or the spread of epididymitis can all lead to unilateral testicular swelling and congestion.

Varicose vein

Unilateral testicular swelling and congestion is caused by the dilation of the vascular valves in the spermatic vein. The lesions are more common on the left side. Sometimes it may be accompanied by male infertility. After high ligation of the vein, the semen quality of 70% of patients can be improved. Right varicocele is sometimes accompanied by retroperitoneal diseases such as tumors. Therefore, special attention should be paid to newly occurred right varicocele, and further detailed examination is necessary.

Parasitic infection

The most common parasitic infection that causes unilateral testicular swelling is filarial infection. It mainly causes lymphatic obstruction, but it is sometimes difficult to distinguish from vascular obstruction. Testicular inflammation caused by filarial infection is mostly unilateral, sometimes accompanied by hydrocele and thickening of the tunica vaginalis. The hydrocele can be chylous.

Testicular trauma

Unilateral testicular swelling and hyperemia Various injuries to the perineum can affect the testicles and cause unilateral testicular swelling.

Viral infections

Mumps-induced testicular hemorrhage accounts for about 20% of viral orchitis. It usually occurs on the 7th day after the onset of mumps. Occasionally, simple testicular hyperemia without mumps symptoms can be seen. Testicular atrophy will occur in dozens of patients, but due to the swelling and hyperemia of one side of the testicle, the chance of causing infertility is not high. Other viruses that may cause swelling and hyperemia of one side of the testicle include Coxsackie virus and FI3 virus. It may also be accompanied by mononucleosis.
