Varicocele is an abnormal dilatation, elongation and tortuosity of the trabecular plexus in the spermatic cord. The prevalence of this condition is about 20% in the general male population and about 40% in infertile men. It is most commonly seen in young and middle-aged men and is more often seen on the left side. Varicocele is usually asymptomatic and is found during a routine physical examination, or during a painless worm-like mass in the scrotum during a self-examination, or during a visit for infertility. Some patients may have symptoms such as cramping, vague pain and discomfort, which may be aggravated after prolonged standing or walking and may be relieved or disappear after lying down. It may be combined with varicose veins of the lower extremities, hemorrhoids and other diseases. Some patients are found at the consultation due to infertility.
