Varicocele is more common on left side because
|A||Left testicular vein drains into left renal vein|
|B||Left testicular vein drains into inferior vena cava|
|C||Left kidney is lower than right kidney|
|D||Left testis is heavy than right one|
a. Varicocele is a result of dilation of veins that drain into the internal spermatic veins. About 10% of young men have varicoceles, with the left side most commonly affected.
b. Typically, varicoceles arise secondary to incompetent internal spermatic vein valves. However, the presence of unilateral right-sided varicocele raises the suspicion of poor drainage at the junction of the right testicular vein and right renal vein, which could be secondary to a large right-sided renal mass.
c. In addition, the sudden onset of varicocele in an older man raises the suspicion of a retroperitoneal mass leading to inadequate drainage of the testicular veins.
d. Examination of a man with varicocele when he is upright reveals a mass of dilated, tortuous veins lying posterior to and above the testis.
f. Sperm concentration and motility is significantly decreased in 65% to 75% of subjects.
g. Infertility is observed in a higher percentage of individuals with varicoceles than the rest of the population.
h. Surgical ligation for the dilated internal spermatic veins may restore fertility; however, in the absence of infertility, poor testicular growth in the adolescent, or patient discomfort, surgical intervention is not indicated.
