About the symptom

A varicocele is enlargement of the veins that run along the spermatic cord and are seen in the scrotal area. The size and severity can vary, as some become visible only when you hold your breathe while others may be present on their own. Generally they do not cause any issues, however may be surgically treated if they become painful or as part of an infertility assessment.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Scrotal pain

Possible causes

  • Varicocele

    A varicocele is a condition where the veins in your scrotum become enlarged. The exact cause is unknown, but experts believe that it may be due to defective valves in the veins within your scrotum. The valves regulate the flow of blood to and from the testicles. It may also occur from compression of a vein by nearby structures. Varicoceles may lead to decreased sperm production and quality.

  • Hydrocele

    A swelling of the scrotum caused by fluid collecting in the space around a testicle. It is common in newborns, older boys, and men and can be caused by inflammation or injury.
