Varicocele as a progressive lesion: positive effect of varicocele repair.
Varicoceles are the leading correctable cause of infertility in men who present to an infertility clinic for evaluation. Consequently, the surgical correction of a varicocele, known as a varicocelectomy, is the most commonly performed operation for the treatment of male infertility. The current data suggest that an individual with a varicocele, even with a previously normal semen analysis or documentation of previous fertility, is at risk for subsequent loss of testicular function and infertility. Many of these patients will need to be treated because there is convincing evidence that a varicocele may have a progressive toxic effect on the testes that may ultimately result in irreversible infertility if left untreated. Identifying those individuals with varicoceles that will ultimately cause fertility impairment is still beyond our current clinical capabilities. Current investigative modalities, e.g. semen analysis, testicular measurement, serum gonadotrophin determination, gonadotrophin-releasing hormone (GnRH) stimulation test, and testis biopsy analysis, may be employed to detect early changes in testicular physiology produced by a varicocele.
