Many studies with different results have been conducted regarding varicocelectomy in
patients with subclinical varicocele and its effect on semen parameters. This clinical trial was aimed at
assessing the effect of varicocelectomy on the spermiogram of patients with subclinical varicocele. A
total of 142 patients with varicocele (79 clinical and 63 subclinical) took part in the study. Two
spermiograms were taken from the patients, one before and the other 3 to 6 months after
varicocelectomy. Although the spermiogram results of the patients with subclinical varicocele did not
show a significant change after operation, the spermiogram of the patients with clinical varicocele
improved significantly (P < 0.05). In the patients with subclinical varicocele, bilateral and right
varicoceles were more prevalent compared to group with clinical varicocele (P < 0.05). In addition,
incidence of secondary infertility in the patients with subclinical varicoceles was higher in comparison
with the other group (P < 0.05). Consideration of the ineffectiveness of operation in patients with
subclinical varicoceles and considerable clinical differences between these patients and patients with
clinical varicocele, we recommend avoiding surgery in these patients unless no other causes of semen
abnormality, such as hormonal abnormality, internal urogenital abnormality or immunological disorders
can be found.
