“…Consequently, the surgical correction of this condition, known as varicocelectomy, is the most commonly performed operation in infertility. Although, there are numerous studies showing improvement in both semen quality and pregnancy rate after varicocele repair [11,13,20], some authors report that varicocele treatment brings neither improvement of sperm quality nor pregnancy rates [1,14]. It is not definite whether varicocelectomy in azoospermic patients with spermatogenic failure is related with the possibility of spermatogenesis.…”

“…There are many unresolved clinical questions related to varicoceles, for instance, as to whether subclinical varicoceles should be diagnosed and treated (6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Therefore, even though recent progress in diagnostic methods has revealed a higher incidence of subclinical varicoceles, the clinical significance of this is controversial as regards male infertility (1,2,16).…”

“…However, this point is debated by the scientific literature because even prospective randomized controlled trials of varicocele treatment in adults have given conflicting results. Studies on this topic are divided into those that conclude there is no influence on infertility by treatment of varicocele (6,7,14,15) and those that find a real benefit on semen parameters and pregnancy rate (8,9).…”
