Abstract
Varicocele is present in almost 35-40% of men presenting with primary infertility. Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. To the best of our knowledge, only a few systematic reviews and meta-analyses (SRMA) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility using a before-after analytic approach for analyzing 22, 17, and 5 prospective uncontrolled trials, respectively. Indeed, the majority of SRMAs have focused on pregnancy rate as an outcome. This study aimed to evaluate the effect of VR on conventional semen parameters in infertile patients with clinical varicocele compared to untreated controls.
