“…15 Many studies have reported that surgical correction of a varicocele improves sperm parameters and increases the chances of pregnancy. 4,16,17 Surgical correction of a varicocele might not prevent further testicular atrophy, but can result in a catch-up growth period of several years, especially when the surgery is carried out during the late adolescent period. [18][19][20] Furthermore, studies comparing seminal parameters of adolescents and adults after varicocelectomy showed that seminal results improved more rapidly after surgery in the adolescent group than in the adult group.…”

Objective:We carried out a nationwide epidemiological study to evaluate the prevalence and effect of varicoceles on testicular volume in South Korean adolescents. We also investigated the correlation between varicoceles and body mass index (BMI). Methods: In this prospective study, physical examinations were carried out to assess the presence and severity of varicoceles in middle school boys from six regions of South Korea. Testicular volume, height and weight of all boys were measured. The prevalence of varicoceles was assessed. The associations between age, testicular volume, BMI, and the presence and severity of varicoceles were examined. Results: A total of 1938 boys with a mean age of 14.1 years (range 13-16 years) were screened. A varicocele was found on the left side in 295 (15.2%) boys and on the right side in 8 (0.4%) boys. Bilateral varicoceles were found in 17 (0.9%) individuals. Of the subjects with a left varicocele, 151 (51.2%), 80 (27.1%) and 64 (25.1%) boys had a grade 1, 2 or 3 varicocele, respectively. The prevalence of varicoceles did not increase with age. The proportion of boys with testicular size discrepancies increased with the severity of the varicocele. After adjusting for age, BMI had a negative correlation with the presence of varicoceles. Conclusions:The prevalence of varicoceles in South Korean middle school boys is 16.5%. The presence of varicoceles seems to have a negative effect on testicular growth. BMI has a significant inverse relationship with the occurrence of varicoceles.

“…Approximately 19% of subfertile men with a clinical varicocele will present with isolated abnormalities in sperm motility 74. In attempts to examine varicocele repair as an intervention for men with varicocele-associated asthenospermia, Boman et al reported a retrospective review of 118 infertile men who met these criteria including 69 who underwent microsurgical varicocelectomy and 49 who chose not to undergo repair.…”

“…Varicocele repair resulted in significant increases in total motile sperm count (30 million/ejaculate compared to 39 million, p <0.05) and spontaneous pregnancy (65% compared to 32%, p<0.01). Interestingly, those who did not undergo repair were more likely to utilize IVF/ICSI (32% compared to 11%, p<0.05) and no differences in pregnancy rates following assisted reproduction (IUI, IVF, and ICSI) were noted 74. Similarly, Schatte et al prospectively examined 61 subfertile men with clinical varicoceles who underwent microsurgical inguinal varicocelectomy and followed postoperatively for increases in sperm parameters.…”

Objective-To evaluate the current literature on the impact and potential mechanisms of varicocele repair on male fertility.Design-Pertinent articles were identified through computer PubMed search on varicocele repair and male infertility. References of selected articles were hand searched for additional citations.Conclusions-Varicocele repair has been shown to reverse a spectrum of effects contributing to men with impaired fertility. Clinical studies on the intervention have illustrated variable effects on postoperative sperm parameters and pregnancy rates. Studies with conflicting results suffer from a significant number of confounding variables, such variable repair technique or lack of controls. Further studies are warranted on the role of modern microsurgical varicocelectomy given the improvements in assisted reproductive technologies.

“…Postoperative improvements in sperm concentration, motility, and morphology have been studied in men with varicoceles. A retrospective study by Boman et al in 2008 examined the effect of varicocelectomy in 69 infertile men with isolated asthenospermia, and found signi fi cant improvement in total motile sperm count (39 million vs. 30 million) and also a doubling of the spontaneous pregnancy rate(65% vs. 32%) when compared to 49 similar men who declined varicocelectomy [ 30 ] . A great number of studies have been published demonstrating the improvement in sperm count/concentration after varicocelectomy.…”

Varicocele can be de fi ned as dilatation or tortuosity (varicosity) of the veins of the pampiniform plexus. Varicoceles are present in approximately 15% of unselected men, in 40% of men presenting with primary infertility, and a much higher percentage of couples with secondary infertility [ 1, 2 ] . Varicoceles are the most commonly seen and correctable cause of male-factor infertility [ 3 ] . Tulloch's report in 1955 [ 4 ] brought to the forefront the proactive treatment and study of varicoceles in the subfertile male. Previously, many investigators felt that varicocele repair was cosmetic or only halted testicular injury at best. Since this time, many studies have demonstrated that improvement in semen parameters and chance of pregnancy are very possible with surgical repair of varicoceles.
