Varicocele is a medical condition characterized by enlarged veins of the pampiniform plexus in the scrotum. It most commonly appears on the left side due to the vertical flow of the left spermatic vein, which enters the left renal vein at a right angle. Conversely, the right renal vein enters the inferior vena cava at an acute angle, reducing the chance of venous blood stasis on that side. The prevalence of varicocele in the average male population is 15%. Varicoceles are often discovered during routine physical examinations or infertility assessments. They appear as soft lumps above the testis, most commonly on the left side of the scrotum. According to the guidelines of the American Urological Association and the American Society for Reproductive Medicine, clinical varicoceles should be treated in men in couples who have been unsuccessfully trying to impregnate the partner for an extended period if the following conditions are met: the varicocele is palpable, the couple has documented infertility, the woman has normal or potentially correctable fertility, or the male partner has one or more abnormal semen parameters or results from sperm function tests. Treatment of varicocele is indicated in patients undergoing infertility evaluation who have symptoms, such as a painful scrotum. There is strong evidence that varicocele surgery can restore testicular volume and improve semen parameters. Varicocele treatment can be conducted in two ways: surgical and non-surgical. When deciding on the method of varicocele treatment, it is important to consider the advantages and disadvantages of the approach chosen by the physician.
