A varicocele is a term used to describe abnormal enlargement of the veins within the scrotum. The veins carry blood from the various body organs back to the heart. Typically, veins have valves that prevent blood backflow. When the valves in the veins within the scrotum don’t work as they should, blood tends to collect in the scrotum, leading to varicoceles.
While varicocele is very common, it is not life-threatening. In fact, research shows that about 15 percent of all adult men have varicocele. For most men, the condition will go unnoticed throughout their life or does not cause any complications. Although the condition is not dangerous, varicocele is a common cause of low sperm production and reduced sperm quality, leading to infertility. Varicoceles can also lead to reduced testosterone production and scrotal discomfort. The condition often does not need treatment until there is a reason for concern about the associated problems. Fortunately, varicocele is easy to diagnose and treat.
