A varicocele is swelling in the scrotum associated with the backup of blood in the testicular vein.
A varicocele is caused by a problem in the main vein of the testicle. Blood normally leaves the testicle through the spermatic vein. When this vein is not working properly, the blood gets backed up and the veins bulge.
Varicoceles typically develop in men 15-25 years old. There are no specific factors that increase your risk of getting varicoceles.
Varicoceles may not always have symptoms. When they do appear, symptoms may include:
Varicoceles may cause the testicle to be smaller. It may also contribute to male infertility by reducing sperm quality and/or quantity.
You will be asked about your symptoms and medical history. A physical exam will be done. Varicoceles are usually easily diagnosed by exam. Your doctor may recommend tests to confirm varicoceles or rule out other conditions.
Tests may include:
Talk with your doctor about the best treatment plan for you. Treatment is not required for all varicoceles. Treatment is generally recommended if a varicocele is causing infertility, change in testicle size, or if it is causing pain.
Options may include one or more of the following:
To help ease discomfort, your doctor may recommend over-the-counter pain relievers. In some cases, you may need to wear supportive or athletic underwear.
Surgical treatment options include:
There are no current guidelines to prevent varicoceles.
