What is varicocele in the testes?

Dr. Michael Roizen, MD
Internal Medicine
When you get too much blood flow through the vessels in the groin area, the spermatic veins can swell up so that they feel like a bag of worms; that’s called a varicocele. If you have a varicocele on both sides of the testes (or even one side), your sperm may overheat, which gets them swimming in the wrong directions; if that’s the case, there is a medical way to fix the problem, called varicocele repair. See your doctor.
