A varicocele is bulging of the veins within the loose bag of skin that holds testicles. A varicocele is akin to a varicose vein that affects the legs. Varicocele is one of the causes of infertility in men leading to low sperm production and poor sperm quality, which could result in male infertility. It is unclear what triggers varicoceles. It is not necessary that all varicoceles impact sperm production. In majority of instances, varicoceles develop over a period.
Varicoceles can be classified as Grade 1, Grade 2 and Grade 3 varicoceles. Grade 1 and 2 varicoceles are not visible but can be detected during a physical examination by the doctor, while a Grade 3 varicocele easily identifiable. Depending on the grade of varicocele present, some individuals may not require treatment. As time progresses, there may be swelling of varicoceles and it becomes more visible. Further, if a varicocele results in symptoms, it can be treated surgically.
Varicoceles usually form during puberty and develop over time. They may cause some discomfort or pain, but they often result in no symptoms or complications.
