A varicocele occurs in the scrotum. The scrotum is a loose sac of skin that holds your testicles. It also has the arteries and veins (pampiniform plexus) that carry blood to the reproductive glands. A swelling and enlargement of the veins within the scrotum may result in a varicocele. It might feel like a bag of worms and is quite similar to a varicose vein that occurs in the leg. More common in males aged 15 to 25, varicoceles can be found in 20 percent of adolescent male population and around 15 percent of the adult males.
Varicoceles form during puberty, and are more commonly found on the left side of your scrotum. At the same time, varicoceles can exist on both sides, but this case is extremely rare. The anatomy of both the sides of your scrotum isn’t the same; varicoceles can grow larger and easier to notice over time. The pampiniform plexus cools blood in the testicular artery before it gets into the testicles. It assists it in keeping it at the temperature needed to make sperm. A varicocele is a common cause of decreased sperm production and low sperm quality, which in some cases can lead to infertility. Not all varicoceles affect sperm production but it can shrink the testicles. It can be painful or uncomfortable.
Usually, varicoceles are easy to diagnose and may not need treatment. If symptoms occur, you need to see a Urologist.
