Varicocele occurs when the veins of the scrotum become enlarged, similar to a varicose vein.
A varicocele is an enlargement of the veins of the scrotum (pouch of skin that contains the testicles). It has no known cause. A varicocele is similar to a varicose vein that can develop in the leg. This condition can cause low sperm count and decreased sperm quality.
In most cases, a varicocele causes no symptoms. When it does cause pain, the pain may:
- Improve when you lie on your back
- Increase when standing or exercising
- Vary from sharp to dull discomfort
- Worsen throughout the day
