Testicular hydrocele is a condition that alters the size of the testicles, making them larger. In some cases, it can affect self-esteem and sexual quality of life. Learn more below.
In most cases, the condition does not pose a serious health risk but can cause physical and aesthetic discomfort, affecting sexual relationships, daily life, and the patient’s self-esteem, while raising questions about fertility impacts.
Continue reading this guide to learn more about testicular hydrocele, including symptoms, treatment options, and how to handle this condition calmly.
What Is Testicular Hydrocele?
Testicular hydrocele is characterized by the accumulation of serous fluid in the membrane surrounding the testicle. This condition can occur in one or both testicles, known as unilateral or bilateral hydrocele, respectively.
Although it’s more common in newborns, it can also affect men over 45. Around 1% of adults worldwide are affected.
While generally painless, hydrocele causes testicular swelling, altering their appearance and worrying men.

Causes of Testicular Hydrocele in Children and Adults
The causes of this condition differ between children and adults.
In newborns, testicular hydrocele is usually caused by a failure in closing the channel connecting the abdomen to the scrotum during fetal development.
In adults, it often results from trauma, infections, or inflammations, such as those caused by sexually transmitted diseases or orchiepididymitis. Aging is also a risk factor, as the lymphatic system’s efficiency may decrease, leading to fluid accumulation.
Is Testicular Hydrocele Dangerous?
In most cases, testicular hydrocele does not pose severe health risks. However, medical evaluation is still necessary!
It’s crucial to investigate the condition since other diseases, like inguinal hernias or even testicular tumors, can have similar symptoms. Contrary to myths, hydrocele does not turn into cancer.
Even though it is not dangerous, the condition may cause discomfort that affects a man’s life. Treatment can help manage the symptoms.
Symptoms
The main symptoms of testicular hydrocele are:
- Increased testicle size
- Testicular swelling (usually painless)
- Heaviness in the scrotal area
In children, parents may notice changes in testicle size, while in adults, symptoms are more evident after long periods of standing or engaging in physical activities.
When to Seek Medical Help?
Although not a medical emergency in most cases, it’s essential to see a urologist if you notice testicular swelling or any changes in testicle size, as advanced cases may become bothersome.
If pain, redness, or sudden onset occurs, visit a doctor immediately, as it may indicate other associated conditions.
Diagnosis
Testicular hydrocele diagnosis is done through a physical examination and a test called transillumination. This test uses light to check for fluid in the scrotum. If the scrotum appears translucent, the diagnosis is confirmed.
Additional exams, like ultrasound, may be recommended to rule out other conditions, such as hernias or tumors.

Recommended Treatments
Treatment for testicular hydrocele varies based on age, severity, and associated discomfort.
In children, the condition often resolves on its own by age 2.
For adults or persistent cases, surgical intervention might be required. The procedure, called hydrocelectomy, removes excess fluid. Sclerotherapy, a minimally invasive procedure involving the injection of a sclerosing agent, may also be an alternative in some cases.
Does Hydrocele Affect Fertility or Erectile Function?
Although it involves the testicles, testicular hydrocele rarely affects fertility or causes erectile dysfunction.
However, in severe cases, significant scrotal swelling can cause discomfort during sexual activity. This may lead to psychological issues such as erectile dysfunction or low libido.
While benign, testicular hydrocele requires medical attention to ensure proper diagnosis and treatment, promoting a healthier approach to managing the condition.
If you notice any changes in testicle size or signs of swelling, schedule a consultation with your urologist to stay on top of your male health.
