Overview

abstract

  • Varicocele is an extremely common entity, present in 15% of the male population. Varicoceles are found in approximately 35% of men with primary infertility but 75%-81% of men with secondary infertility. Mounting evidence clearly demonstrates that varicocele causes progressive duration-dependent injury to the testis. Larger varicoceles appear to cause more damage than small varicoceles and, conversely, repair of large varicoceles results in greater improvement of semen quality. Varicocelectomy can halt the progressive duration-dependent decline in semen quality found in men with varicoceles. The earlier the age at which varicocele is repaired, the more likely is recovery of spermatogenic function. Varicocelectomy can also improve Leydig cell function resulting in increased testosterone levels. The most common complications after varicocelectomy are hydrocele formation, testicular artery injury and varicocele persistence or recurrence. The incidence of these complications can be reduced by employing microsurgical techniques, with inguinal or subinguinal operations, and exposure of the external spermatic and scrotal veins. Employment of these advanced techniques of varicocelectomy provide a safe, effective approach to elimination of varicocele, preservation of testicular function and, in a substantial number of men, an increase in semen quality and likelihood of pregnancy.
