Therapeutic implications of left, right, and bilateral varicocelectomy.

It now appears that the incidence of bilateral varicoceles in infertile men with varicocele may be around 50 per cent to 60 per cent. Infertile men should be examined carefully for varicoceles on both sides, and bilateral varicocelectomy should be performed when indicated. Furthermore, we have demonstrated that selected infertile patients who have failed to improve after left varicocelectomy may yet improve after correction of the right varicocele.
