TL;DR: This study indicates that surgery in adolescence can be useful, possibly because the testis is still developing at that age, and large-scale, double-blind controlled trials on early treatment of left varicocele are needed to identify possible markers of disease severity.

TL;DR: The prevalence and site ofvaricocele and varicocele‐related testicular atrophy in children and adolescents is determined and the cause and location of disease is investigated.
Abstract: Objective To determine the prevalence and site of varicocele and varicocele-related testicular atrophy in children and adolescents. Patients and methods The study included 4052 boys aged of 2–19 years, divided into four age groups; the findings of a physical examination, any testicular atrophy and testicular volume were recorded. Results Varicocele was detected in 293 (7.2%) of the 4052 boys; the prevalence was 0.79% in those aged 2–6 years, 0.96% at 7–10 years, 7.8% at 11–14 years and 14.1% at 15–19 years. The prevalence was 0.92% in 1232 children aged 2–10 years and 11.0% in 2531 adolescents aged 11–19 years (P < 0.001). The prevalence increased significantly at age 13 years (P < 0.005). The varicocele was unilateral in 263 of the 293 (89.7%) boys with varicocele; of these, one (0.38%) was on the right and the others on the left side. Varicoceles were bilateral in 30 of 279 boys (10.8%) aged 11–19 years but none were detected in those aged < 11 years. Varicocele-related testicular atrophy was not present in those aged < 11 years, but seven boys (7.3%) aged 11–14 years and 17 (9.3%) aged 15–19 years had testicular atrophy. The difference in prevalence between the last two age groups with atrophy was not significant. Conclusion These findings support the view that varicocele is a progressive disease and that the prevalence of varicocele and testicular atrophy increases with the puberty.

TL;DR: While there was catch-up growth in comparison to the contralateral testis, testicular consistency improved but testicular volumes may not increase significantly after varicocele repair at ages older than 14 years, in these adolescents postoperative semen parameters and serum hormone values may significantly improve regardless of testicular volume.

TL;DR: Adolescent varicocele repair improves semen parameters and is a safe method with low recurrence and low complication rates, suggests this study, which suggests that the postoperative complication rate significantly decreases with use of higher magnification, such as microscopy.

TL;DR: The correlation of varicocele to sperm parameters and to sperm function tests, such as binding capacity, hypo-osmotic swelling test, presence of reactive oxygen species, and in particular, the correlation to fertility potential is surveyed.
Abstract: Despite the numerous studies published over the past decade, the role of varicocele in male infertility is still controversial. Although more frequent in infertile men, its influence on sperm production or function has not, as yet, been determined. Moreover, the exact mechanism of varicocele action is not clear. We have surveyed the literature, the correlation of varicocele to sperm parameters and to sperm function tests, such as binding capacity, hypo-osmotic swelling test, presence of reactive oxygen species, and in particular, the correlation to fertility potential. Almost every subject examined had contradictory results. Larger control studies may possibly elucidate and clarify the cases in which varicocele is associated to sperm function, and where treatment may improve fertility.

TL;DR: The epidemiology, etiology, pathophysiology, and treatment of the adolescent with varicocele will provide the reader with tools to make appropriate decisions in dealing with this condition.
Abstract: The finding of varicocele in an adolescent male is common. Varicocele rarely causes symptoms and is often diagnosed on the routine physical examination. There is clear association between varicocele and male factor infertility; however, there is debate about whether, when, and whom to treat when present in adult or adolescent males. This review of the epidemiology, etiology, pathophysiology, and treatment of the adolescent with varicocele will provide the reader with tools to make appropriate decisions in dealing with this condition.
