Causes and Symptoms
Varicocele is a medical condition that is characterized by the enlargement of veins within the scrotum or the loose bag of skin that holds the testicles. Varicoceles are similar to the varicose veins found in the leg, and they begin to form during puberty. They are usually found on the left side of the scrotum, but they can also be present on both sides. However, it is extremely rare for them to appear on both the right and left side.
While varicocele is a typical cause of infertility in men because it can lead to low production of sperm and decreased sperm quality, not all varicoceles can actually affect sperm production. Aside from fertility, varicoceles can also hamper the normal development of the testicles and even cause them to shrink.
Furthermore, they can easily be diagnosed and don’t require treatment in many cases. However, if the varicocele produces symptoms, it is usually repaired through varicocele surgery.
