66 nonobstructive azoospermic men with normal genetic analysis composed of 32 (48%) patients with and 34 (52%) patients without varicocele were evaluated for the rate of sperm extraction five months after the varicocelectomy. Sperm retrieval was successful in 22 of 32 patients (68%) who had been, operated because of varicocele and in 13 of 34 patients (38.2%) who had no varicocele (OR = 3.55) (CI: 1.15-11.27) (p = 0.025). Overall, sperm extraction was successful in 35 of 66 patients (53%). Repair of varicocele in non-obstructive azoospermic patients may return spermatogenesis to normal in spermatogenetic focuses. So, the presence of varicocele and its treatment might be considered as a prognostic factor for sperm retrieval in these patients.
