The role of varicocele repair in nonobstructive azoospermia must be evaluated with controlled trials rather than observational studies.

摘要

Certainly, varicoceles can have a substantive effect on sperm production in infertile males. In addition, varicocele repair may optimize sperm production. However, additional studies and evaluation of the role of varicocele repair in men with this condition (nonobstructive azoospermia) are warranted.
