A varicocele is an enlarged vein within the scrotum (the skin that holds the testicles). A varicocele is similar to a varicose vein that you might find in your leg. This can be a common cause of male fertility problems as it affects the health of the sperm.

Fortunately, a varicocele can be easy to diagnose and treat. In a lot of cases, a varicocele will not cause any symptoms. In more rare cases, you may experience symptoms such as:

  • Sharp or dull discomfort

  • Pain that gets worse when you stand for a long period of time

  • Pain that worsens over the course of the day

  • Pain that improves when laying down

  • Problems with fertility

Over time the varicocele may become bigger and more noticeable. This can be compared to a ‘bag of worms’ and often cause swelling to the testicle. Varicocele’s are almost always found in the left testicle and will often develop during puberty.

As stated before, a varicocele will often cause no symptoms and will therefore not need any treatment. Patients will often be unaware of a varicocele until it is picked up by a fertility specialist. If you notice a lump in your scrotum or abnormal swelling it is important that you go and see a doctor, as it could be caused by a varicocele or something more serious.

The exact cause of a varicocele is unknown; however, experts believe that it is linked to lack of blood flow to the testicle. This causes the veins to widen.

A varicocele can be diagnosed from a physical examination. Once it has been diagnosed it can be corrected with surgery to redirect the blood flow into normal veins.
