Overview
A varicocele is an enlargement of the veins within the scrotum, rather like varicose veins in the leg, usually on the left side. It is common and often causes no symptoms, but some men notice a dull ache or a soft, bag-of-worms feeling in the scrotum, worse on standing. It matters mainly because it is a recognised and treatable cause of reduced fertility. Many need no treatment; a painful varicocele or one affecting fertility can be corrected with a minor procedure.
Symptoms
- A soft, bag-of-worms feeling of veins in the scrotum
- A dull ache or heaviness, worse on standing or exertion
- Swelling usually on the left side of the scrotum
- Discomfort that eases on lying down
- In some, reduced fertility or a smaller testicle
When to see a doctor
See a doctor for scrotal aching or swelling, or if you are having difficulty conceiving — a varicocele is a treatable cause.
Causes
Faulty valves in the veins of the scrotum that let blood pool and the veins enlarge, similar to varicose veins.
