Varicocele is a common disease in young adults due to obstruction of venous reflux or valve failure in the spermatic cord, blood regurgitation causing stagnation of blood flow, abnormal lengthening of the trabecular plexus, and tortuous expansion. Varicocele has a negative impact on reproductive function, manifested by poor sperm motility, low sperm density, and abnormal sperm morphology, which can cause male infertility. The typical symptoms of varicocele are distension of the scrotum when standing, a sensation of falling, and a vague dull pain in the testicles, which is aggravated by excessive walking or labor and radiates to the lower abdomen, groin, and lower back. Varicocele with infertility or semen abnormalities should be treated surgically regardless of the presence or absence of symptoms. Varicocele in adolescents should also be operated as early as possible to avoid affecting the reproductive function. The commonly used surgical procedure is high level ligation of the spermatic veins. In addition, laparoscopic ligation of the spermatic vein is simple, less invasive, and has a faster recovery, which is becoming more and more acceptable to more patients.
