Varicocele Repair in Patients With Nonobstructive Azoospermia: A Meta-Analysis

Infertile men with nonobstructive azoospermia can have improvement in semen analysis and achieve spontaneous pregnancy after repair of clinical varicoceles. This meta-analysis demonstrates that men with late maturation arrest and hypospermatogenesis have a higher probability of success and, therefore, histopathology should be considered before varicocele repair in men with nonobstructive azoospermia.
