If you're a male experiencing one of the following symptoms, it may be caused by a medical condition known as a varicocele:

  • Testicular pain
  • Noticeably smaller testicles
  • Infertility

You may even have more than one affected vein, and they may look enlarged or bunched together—like a “bag of worms." If so, you may be affected by varicoceles, a varicose vein of the testicle. Varicoceles affect about 15 percent of men in general and about 30-40 percent of infertile men. Over 90 percent of varicoceles occur on the left side, but they can affect the function of both testicles.The good news is, varicoceles are very treatable.
