A varicocele (VAR-ih-koe-seel) is an enlargement of the veins within the scrotum, the loose bag of skin that holds your testicles. A varicocele is similar to a varicose vein that can occur in your leg.
Varicoceles are a common cause of low sperm production and decreased sperm quality, although not all varicoceles affect sperm production. Varicoceles also can cause testicles to shrink.
Most varicoceles develop over time. Fortunately, most varicoceles are easy to diagnose and, if they cause symptoms, can be repaired surgically.
