Abstract
PURPOSE Andrological pathologies in the adulthood are often the results of conditions that originate during childhood and adolescence and sometimes even during gestation and neonatal period. Unfortunately, the reports in the literature concerning pediatric andrological diseases are scares and mainly concerning single issues. Furthermore, no shared position statement are so far available. METHODS The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving the Italian Society of Pediatric Endocrinology and Diabetology (SIEDP) to provide an updated guideline on the diagnosis and management of andrological disorders from childhood and adolescence to transition age. Derived recommendations were based on the grading of recommendations, assessment, development, and evaluation (GRADE) system. RESULTS A literature search of articles in English for the term "varicoceles", "gynecomastia", "fertility preservation", "macroorchidism", "precocious puberty" and "pubertal delay" has been performed. Three major aspects for each considered disorder were assessed including diagnosis, clinical management, and treatment. Recommendations and suggestions have been provided for each of the mentioned andrological disorders. CONCLUSIONS These are the first guidelines based on a multidisciplinary approach that involves important societies related to the field of andrological medicine from pediatric to transition and adult ages. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving andrological and general health of the transitional age.

Size matters: Total testicular volume predicts sperm count in Tanner V varicocele patients. J Pediatr Urol 2024:S1477-5131(24)00270-5. [PMID: 38876892 DOI: 10.1016/j.jpurol.2024.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 04/25/2024] [Accepted: 05/18/2024] [Indexed: 06/16/2024]
Abstract
INTRODUCTION It is known the prevalence of varicoceles in adolescent men is 14-29% but there is debate surrounding implications on fertility. As obtaining a semen analysis (SA) may be challenging, there is need for objective tests as measures of fecundity. Our aim was to investigate the relationship between testicular volume differential (TVD), varicocele grade, and total testicular volume (TTV) on seminal parameters including total motile sperm count (TMSC). MATERIALS AND METHODS We conducted a retrospective single-center chart review over 14 years of 486 Tanner V adolescent males. Three hundred and four met inclusion of palpable, non-operated left-sided varicocele who underwent at least one SA and ultrasound. Abnormal TMSC was defined by World Health Organization 2010 criteria for minimal reference ranges. Multivariate logistic regression, receiver operating characteristic analysis with Youden J-statistic and descriptive statistics were performed. RESULTS Three hundred and four Tanner V adolescents with median age of 18.0 years (18.0-19.0), median TTV of 34.5 cc (28.9, 40.2) and median TMSC of 62.5 million/ejaculate (25.4, 123.4) were evaluated. TTV cutoff of 29.5 cc was found to predict TMSC of <9 million/ejaculate with negative predictive value of 96.2% and odds ratio of 6.08 ([2.13-17.42], p < 0.001). TVD greater than 20% did not reach statistical significance with an odds ratio of 1.66 ([0.41-6.62], p = 0.50). DISCUSSION In clinical practice, each patient will need to have an individualized plan. Based on our data, for older adolescents (17 or 18 years) with varicocele and an abnormal TTV, clinicians may have a lower threshold for advising SA, and if unable to obtain, surgical intervention and/or closer surveillance should be stressed. Patients should be informed of their six-fold increase in abnormal SA. Patients with normal TTV should be advised they are at lower risk of having abnormal SA. Younger patients with varicocele and an initial TVD>20%, should be followed closely but intervention delayed until 17 or 18 to better assess TTV. The importance of trending patient data should be emphasized as a single measurement has low predictive value for developing adolescents. Limitations of our study include a retrospective design and the lack of uniform correlation between adolescent SA and paternity. CONCLUSIONS Total testicular volume less than 29.5 cc increased odds of abnormal semen analysis by over six times and had a negative predictive value of 96.2%. Ultrasound results may be useful for risk stratification and counselling on appropriateness of surgical intervention.

Abstract
OBJECTIVES To assess the evolution of the Testicular Atrophy Index (TAI) in adolescent boys with and without a left varicocele with special attention for the currently postulated cut-off value of 20%. SUBJECTS AND METHODS During 2015-2019, 364 adolescent boys aged 11-16 years were recruited. Genital examination and scrotal ultrasonography were repeatedly performed (≥4 month intervals). Testicular volume (TV) was calculated using the Lambert formula (length × width × height × 0.71). TAI was calculated using the formula: [(TVright - TVleft)/TVlargest (right, left)] × 100. RESULTS The final study population comprised 239 participants, 161 (67.36%) controls and 78 (32.64%) adolescent boys with left varicocele. The mean (sd) number of measurements per participant was 3.82 (1.08). A TAI of ≥20% at first measurement occurred in 9.94% and 35.90%, respectively. Of these, only 31.25% and 46.43% had a TAI of ≥20% at the last measurement, respectively. Nevertheless, the risk of ending up with a TAI of ≥20% was significantly higher if a TAI of ≥20% was recorded at first measurement (P = 0.041 and P = 0.002, respectively). The normalisation rate did not differ significantly between the groups (P = 0.182). Normalisation occurred most frequently in Tanner Stages III and IV. Normalisation was mostly (≥74%) due to catch-up growth of the left testis, in contrast to growth retardation of the right testis, in both groups. The TAI seems to be a fluctuating parameter. CONCLUSION A TAI of ≥20% is a phenomenon seen in boys with and without varicocele but is more common in boys with varicocele. Although normalisation of a high TAI is frequently seen, both adolescent boys with and without a left varicocele who have an initial TAI of ≥20% have a higher risk of a TAI of ≥20% in the future. As the TAI is a fluctuating parameter during pubertal development, it's use as indicator for varicocelectomy based on a single measurement during pubertal development is questioned.

Does Varicocele Treatment in Adolescence Improve Fertility Outcomes in Adulthood? Eur Urol Focus 2023; 9:42-45. [PMID: 36428211 DOI: 10.1016/j.euf.2022.11.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 10/11/2022] [Accepted: 11/11/2022] [Indexed: 11/24/2022]
Abstract
Many questions on diagnosis of varicocele in adolescent patients have yet to be adequately answered, particularly regarding paternity outcomes after treated in comparison to conservative monitoring. There have been some promising outcomes after surgical treatment, particularly microsurgical varicocelectomy, but the results are mixed and may not be comparable because of differing variables. Future studies with robust methodologies are needed to identify which adolescents require treatment and when treatment should be initiated to avoid any detrimental effects on future fertility.

Abstract
INTRODUCTION Determining which patients are negatively affected by varicocele would enable clinicians to better select those men who would benefit most from surgery. Since conventional semen parameters, have been limited in their ability to evaluate the negative effects of varicocele on fertility, specialized laboratory tests have emerged. OBJECTIVE To identify clinical and ultrasound parameters (including PRF) which would negatively influence standard and functional semen variables in young adults with a varicocele. DESIGN Prospective, cross-sectional observational study. SETTING Antwerp University Hospital, Belgium. PATIENT(S) Young volunteers between 16 and 26 years, Tanner 5, were recruited. INTERVENTION(S) Every participant had a scrotal ultrasound to calculate testicular volumes. If a varicocele was present, the grade, vein diameter, peak retrograde flow (PRF) in supine position and spontaneous reflux in standing position were measured. All participants provided a semen sample. Standard semen parameters were analyzed and sperm DNA fragmentation. MAIN OUTCOME MEASURE(S) Of all clinical and ultrasound parameters tested, PRF was an objective tool identifying young adults with a varicocele. PRF was highlighted by the prevalence of SDF, both in the total and vital fractions of the spermatozoa, providing opportunities to manage such 'at-risk' adolescents/young adults. RESULT(S) Total SDF was significantly increased in grade 3 varicocele compared to grade 1 and 2 but no significant difference with vital SDF or standard descriptive semen parameters was seen. Total and vital SDF on the other hand were significantly increased when PRF was above 38.4 cm/s. Standard semen analysis showed no difference with PRF as an independent predictor. Testicular atrophy index, varicocele vein diameter and spontaneous reflux revealed no significant differences in both the descriptive and functional semen variables. DISCUSSION Descriptive semen parameters showed no significant difference between the non-varicocele controls and the varicocele group with low and high PRF. Increased PRF negatively influenced sperm quality via increased DNA fragmentation both in the total as in the vital fractions of the semen. CONCLUSION(S) Of all clinical and ultrasound parameters tested, PRF was an objective non-invasive tool to identify varicocele patients at risk for a high SDF.

Abstract
Varicocele is defined as an abnormal dilation and tortuosity of the internal spermatic veins found within the pampiniform plexus. It is a common finding in adolescents and adult men alike, however its diagnosis in the adolescent population poses different dilemmas in regard to indications for treatment than in adults. Failed Paternity is a clear-cut indication for repair in adult men attempting to father children. In adolescents, the physicians, family and patients must consider potential for future fertility problems which may or may not actually become of concern. Assessing the degree of negative effect of the varicocele on an adolescent's testicular health can also be difficult as teenagers typically are not asked to provide semen for analysis and thus surrogate markers for testicular health such as testicular size differentials must be used. Treatment options for the adolescent varicocele are similar to options in adult populations. While risks and benefits of various techniques can be considered, the gold standard for varicocele repair in adolescents has not been clearly defined. We aim to discuss diagnosis of varicocele, considerations for initiating treatment of varicocele in the adolescent, and techniques for management.

Abstract
INTRODUCTION Varicocele is one of the most frequent disease affecting the fertility potential; OBJECTIVE: the aim of this study is to assess the correlation between clinical and radiological grade of varicocele and hormonal values. STUDY DESIGN The data about adolescents with left unilateral varicocele aged between 13 and 16 years, with Tanner stage V, followed at the Authors' Institution between September 2016 and September 2019 were investigated; inclusion and exclusion criteria were created. Patients underwent standard visit, Ultrasound, Doppler velocimetry and hormonal tests (at T0 and T1). Those patients with testicular hypotrophy underwent surgery. RESULTS During the study period, 75 subjects with left unilateral varicocele were enrolled; 8 patients were excluded.A total of 67 patients were then studied. Among these patients, 37 had testicular hypotrophy, while the others had normal testicular volume. There was no correlation between grade of varicocele and testicular hypotrophy (p = 0.12); among those patients with testicular hypotrophy, there was a statistical correlation with the grade of spermatic vein reflux (grade 4 vs grades 1-2-3) (p = 0.03). Focusing on hormonal values, there was a statistical significant difference between FSH levels, clinical grades of varicocele and grade of spermatic vein reflux: FSH levels were higher in patients with clinical grade 3 varicocele respect to patients with grade 1-2 varicocele and, in particular, patients with grade 3 varicocele, testicular hypotrophy and grade 4 spermatic vein reflux (14 patients) had higher FSH level respect to others (p = 0.02). After surgery there was a significant FSH reduction. CONCLUSIONS Our results demonstrate that higher grade of spermatic vein reflux is associated with testicular hypotrophy and higher FSH levels.

Abstract
The purpose of this pictorial essay is to describe the ultrasonographic and clinical findings of patients with small testes due to a wide range of causes. We retrospectively reviewed the ultrasonographic and clinical findings of various causes of small testes. We present various causes of small testes on ultrasonography including Klinefelter syndrome, testicular torsion, mumps orchitis, inguinal hernia, cryptorchidism, varicocele, and trauma. On ultrasonography, small testes in patients with testicular torsion, mumps orchitis, and trauma usually showed heterogeneous echogenicity. Atrophic testes were homogeneously hypoechoic in patients with cryptorchidism and inguinal hernia and were isoechoic to the normal testis in patients with varicocele. Klinefelter syndrome patients had small hyperechoic or hypoechoic nodules, but the echogenicity of the remnant portion of the testes was homogeneous. Ultrasonography is helpful for detecting small testes and for the differential diagnosis of the various possible causes of small testes.

Abstract
Purpose: To investigate the effect of primary varicocele and related surgery in male infertility through meta-analysis. Methods: A systematic search of the literature was conducted using the Medline, Embase, Cochrane, and CNKI databases. The search was up to September 2019. Article selection proceeded according to the search strategy based on Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. Data were analyzed using RevMan 5.2. A random-effects model was used to calculate the overall combined risk estimates. Results: After screening 687 articles, 4 randomized controlled trials with 349 patients were included. One hundred seventy two patients were addressed in embolization/ligation, with 177 patient's observation treatment. The number of spontaneous pregnancies in the two groups was 41 and 40, respectively. There was no significant difference in pregnancy rate between the operation group and the control group. RR = 1.05 [0.72, 1.54]. Conclusion: There is not enough evidence to explain the surgical treatment of varicocele can improve the natural fertility of the infertile couples, and there is still a need for most of prospective randomized controlled trials to verify the efficacy of varicocele surgery for treating of male infertility. We do not deny the importance of this operation, we just want to call on everyone to strictly grasp the indications of the operation, avoid ineffective medical expenses, and avoid unnecessary pain to patients.

Abstract
Varicocele is the primary cause of male infertility and the interests of research about varicocele have changed in the last years. The aim of the study was to analyse how topics of interests about varicocele have changed in the last two decades. Literature about paediatric varicocele between 2000 and 2018 was reviewed, and the subjects of the articles were analysed, selecting the main and secondary topics of each article. A study of their prevalence over the years was performed. In the research, 625 articles were found but only 169 provided data in the paediatric age. The total percentage of exclusively paediatric works was 27.04%, being above average in Europe, North and South America. The main subject both for Europe and North America was surgical technique, while for Asia it was videolaparoscopy. The main issue in South America was fertility; Africa and Oceania do not have enough publications to make statistics. Paediatric articles account for less than one-third of overall articles. The first interest of research is surgical technique. In Europe, the topics seem to exclude fertility potential.

Santana VP, James ER, Miranda-Furtado CL, Souza MFD, Pompeu CP, Esteves SC, Carrell DT, Aston KI, Jenkins TG, Reis RMD. Differential DNA methylation pattern and sperm quality in men with varicocele. Fertil Steril 2020; 114:770-778. [PMID: 32709382 DOI: 10.1016/j.fertnstert.2020.04.045] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 04/22/2020] [Accepted: 04/22/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To study the global DNA methylation pattern in spermatozoa of patients with varicocele as well as investigate their semen quality. DESIGN Prospective observational case-control study. SETTING University-affiliated hospital. PATIENT(S) A total of 26 men with varicocele and 26 fertile men without the disorder. INTERVENTIONS Analysis of semen quality and sperm DNA methylation patterns. MAIN OUTCOME MEASURE(S) Semen quality evaluated by semen analysis, and sperm DNA methylation patterns investigated using the Infinium MethylationEPIC BeadChip platform. RESULT(S) Men with varicocele displayed decreased semen quality. The sperm DNA methylation analysis showed that men with varicocele exhibit global hypomethylation in comparison with the control group. A total of 59 differentially methylated CpG sites were identified, most of them hypomethylated in the varicocele group. In regional analyses, 1,695 DNA regions were differentially methylated in men with varicocele. These regions show associations with gamete generation, meiotic and meiosis cell cycle, and semen quality based on gene ontology analysis. CONCLUSION(S) Gene ontology results suggest that changes in methylation may be associated with the low semen quality phenotype observed in some varicocele patients because the observed differentially methylated regions in varicocele patients are related to male reproductive pathways. Additionally, the varicocele grade may influence the magnitude of global sperm DNA methylation change. To our knowledge, this is the first report analyzing changes at a regional or CpG-specific level in men with varicocele.

Abstract
The prevalence of varicocele in children is less than 1% and in 11- to 19-year-old boys 8-14%. Up to 15% of patients with varicocele have impaired fertility. The indication for therapy of varicocele is still controversially discussed. In clinical trials testicular volume, volume difference, semen quality, fertility, hormones and pain have been investigated. The results are very heterogeneous for all parameters, so that the evidence level of recommendations for therapy of varicocele is very low. Nevertheless, the EAU guidelines recommend therapy of varicocele in children and young adults in case of small testis (volume difference >2 ml or 20%), additional cryptorchism, bilateral palpable varicoceles, symptomatic varicoceles and in case of pathological semen (in older boys). Microsurgical inguinal and laparoscopic procedures with preservation of lymph vessels have the best success and lowest complication rates.

Abstract
Pediatric varicocele has an overall prevalence of 15%, being more frequent as puberty begins. It can damage testicular function, interfering with Sertoli cell proliferation and hormone secretion, testicular growth and spermatogenesis. Proper management has a pivotal role for future fertility preservation. The aim of this review was to discuss the diagnosis, management and treatment of childhood and adolescent varicocele from an endocrinologic perspective, illustrating the current evidence of the European Society of Pediatric Urology (ESPU), the European Association of Urology (EAU), the American Urological Association (AUA) and the American Society for Reproductive Medicine (ASRM) scientific societies. According to the ASRM/ESPU/AUA practice committee, the treatment of adolescent varicocele is indicated in the case of decreased testicular volume or sperm abnormalities, while it is contraindicated in subclinical varicocele. The recent EAS/ESPU meta-analysis reports that moderate evidence exists on the benefits of varicocele treatment in children and adolescents in terms of testicular volume and sperm concentration increase. No specific phenotype in terms of testicular volume cut-off or peak retrograde flow (PRF) is indicated. Based on current evidence, we suggest that conservative management may be suggested in patients with PRF < 30 cm/s, testicular asymmetry < 10% and no evidence of sperm and hormonal abnormalities. In patients with 10-20% testicular volume asymmetry or 30 < PRF ≤ 38 cm/s or sperm abnormalities, careful follow-up may ensue. In the case of absent catch-up growth or sperm recovery, varicocele repair should be suggested. Finally, treatment can be proposed at the initial consultation in painful varicocele, testicular volume asymmetry ≥ 20%, PRF > 38 cm/s, infertility and failure of testicular development.

Abstract
Varicoceles exert deleterious effect on testicular function. The condition has been associated with male infertility, testicular hypotrophy and pain. These comprises the common indications for varicocele repair currently. Significant improvement in semen parameters and pregnancy outcomes had been suggested by reports decades ago. However, selection of the best candidates remains an issue since not all patients respond positively to treatment. Consensus has been reached in recent decade after the publication of a series of meta-analyses. Significant improvement in pregnancy outcomes were reported in patients with clinical varicocele and abnormal semen parameters. Varicocelectomy in adolescents with testicular hypotrophy was supported by the positive implication on catch-up growth and semen parameters. However, little is known about the treatment effect of adolescence varicocelectomy on long term fertility and paternity rate. Recent studies on outcome of varicocele repair for pain consistently demonstrated a resolution rate of approximately 90% and support varicocele-associated pain as an indication for surgery. Alternate indications for varicocele repair have been proposed in recent decade. Despite the encouraging preliminary data, most studies were uncontrolled retrospective series. Although varicocelectomy may not obviate the need for assisted reproductive techniques in patients with non-obstructive azoospermia, it potentially increases sperm retrieval rate. The significant increase in serum testosterone after varicocelectomy in patients with androgen deficiency may open an alternative treatment for hypogonadism. The adjunctive role of varicocelectomy before assisted reproduction and the significant decrease in sperm DNA fragmentation after varicocele repair deserve further well-designed controlled studies.

Abstract
INTRODUCTION Testicular volume (TV) can be obtained by either scrotal ultrasound (SU) or orchidometer. Scrotal ultrasound allows for a more objective measurement; however, the interobserver and intra-observer variability of TV measurements has not been rigorously studied. OBJECTIVE The authors measured intra-observer and interobserver variability of SU TV measurements in pediatric patients to assess the reliability and reproducibility of SU. Special attention was paid to how often a 20% discrepancy in TV was noted as this has previously been utilized as an indication for varicocelectomy. DESIGN Patients with an indication for SU or undergoing an ultrasound for another reason were prospectively recruited. Two different urologic specific ultrasound technicians (A and B) performed SU to assess interobserver variability. A second measurement was taken by technician A within 90 days to assess intra-observer variability (A vs A1). The technicians were blinded to other ultrasound results. RESULTS Fourteen patients (28 testes, 56 volume measurements) were included in the intra-observer group and 17 patients (34 testes, 68 volume measurements) in the interobserver group. The mean time to repeat intra-observer ultrasound measurements (range) was 46 days (23-84). Mean age (range) in the intra-observer group was 14.3 years (11-19) and 14.1 years (11-19) in the interobserver group. Indication for ultrasound was varicocele (n = 6), scrotal pain (4), hydronephrosis (3), hydrocele (2), epididymal cyst (2), posterior urethral valves (1), and testis asymmetry (1). Utilizing Bland-Altman analysis and plots, variability was seen in both intra-observer and interobserver measurements. The mean values for testicular sizes for technician A and technician B were 13.0 ± 9.7 cm3 vs 13.8 ± 9.9 cm3, respectively. The mean values for TV measurement for technician A's first and second measurements (A, A1) were 14.3 ± 9.7 cm3 and 14.8 ± 8.9 cm3, respectively. An errant 20% difference in TV measurements for the same testis was seen in 25% (7 of 28) of intra-observer measurements and 35% (12 of 34) of interobserver measurements. These 20% differences were more common with a lower body mass index (odds ratio, OR = 0.74, p = 0.01) in the interobserver group, and lower TV was a predictor in the intra-observer group (OR: 0.82, p = 0.009). CONCLUSIONS Variability exists in both interobserver and intra-observer measurements of TV by dedicated urologic ultrasonographers, and greater than 20% of differences in measured TV in same testicles occurred in over 25% of cases. Caution should be exercised in basing operative decisions and scientific studies on limited measurements of TV.

Abstract
INTRODUCTION/OBJECTIVE Varicocele is a common condition seen in adolescence and associated with adult subfertility. Numerous types of intervention have been described with differences in success and complication rates. This study aims to review and compare the surgical outcomes of laparoscopic Palomo surgery and scrotal antegrade sclerotherapy at our center. STUDY DESIGN A retrospective analysis was done of all patients younger than 18 years old with idiopathic varicocele treated operatively between February 2001 and December 2016. Demographics such as age at operation, side, varicocele grade, operative date, and types of operation were collected. Primary outcomes were clinical recurrence, defined as any grading noted on follow-up within 1 year post-op and post-operative hydrocele. Secondary outcomes were operative time, length of stay, and other surgical complications. Mann-Whitney U test, independent t test and chi-square tests were used for analysis. All p-values were two-sided and considered statistically significant at p ≤ 0.05. RESULTS A total of 119 patients fit the criteria, of whom 117 patients were included in data analysis (Table). Sixty-two patients had laparoscopic Palomo surgery (LPS) and 55 had scrotal antegrade sclerotherapy (SAS). Clinical recurrence (grade 2-3) within 1 year was similar between the two groups, with four out of 48 patients in the SAS group and six out of 62 patients in the LPS group (8.4% in SAS vs. 9.7% in LPS, p = 1.00). Of the 11 patients who had recurrence in the SAS group, seven had grade 1 recurrence (14.5%), two (4.2%) had grade 2 recurrence, and two (4.2%) had grade 3 recurrence. For the LPS group, 17 out of 62 patients had clinical recurrence within 1 year, of whom 11 (17.7%) had grade 1 recurrence, one (1.6%) had grade 2, and five (8.1%) had grade 3 recurrence. Post-operative hydrocele was significantly higher in the LPS group; there was none in the SAS group but 11 patients in the LPS group (0% in SAS vs. 17.7%, p = 0.002). Three patients had clinically significant hydrocele requiring Jaboulays' procedure. Complications other than hydrocele were noted in three patients in the SAS group and one patient in the LPS group (5.5% in SAS vs. 1.6% in LPS, p = 0.158). None required operative intervention. No conversion to open procedure was seen in the LPS group and there were no perioperative complications. Mean operative time was 62.9 min in the SAS group and 60.7 min in the LPS group (p = 0.624). Mean length of stay was 17.5 h in the SAS group and 31.7 h in the LPS group (p < 0.001). CONCLUSION Both SAS and LPS are safe procedures for treatment of adolescent varicocele with similar clinical recurrence rate within 1 year. SAS has a significantly lower rate of post-operative hydrocele.

Abstract
A varicocele is an abnormal dilation of the pampiniform plexus of veins in the scrotum which begins at puberty in approximately 15% of males. Although common in the general population and often asymptomatic, varicoceles are associated with gonadal dysfunction including testicular atrophy, infertility, and hypogonadism in a subset of men diagnosed later in life. Because of the high prevalence and uncertain pathogenesis, definitive management guidelines for varicoceles diagnosed in the pediatric and adolescent population remain poorly defined. The varicocele is the most common etiology of male factor infertility, and treatment in the pediatric and adolescent population may improve semen quality and improve fecundity in adulthood. Evaluation of the pediatric and adolescent varicocele should include history, physical exam, and measurement of testicular volume with orchidometer or ultrasound. Testicular volume differentials and peak retrograde flow on Doppler ultrasonography are important factors in risk stratification of the pediatric varicocele population. Semen analysis and reproductive endocrine assessment should also be considered as part of the workup for adolescent patients. A variety of treatment approaches exist for varicocele, and while the microsurgical subinguinal approach is the gold standard for the adult population, it has yet to be confirmed as superior for the adolescent population. Referral to an andrologist for the adolescent patient with varicocele should be considered in equivocal cases. While active treatment of varicocele in the pediatric and adolescent population is controversial, it is clear that some untreated patients will suffer symptoms later in life, while overtreatment remains a concern for this large, vulnerable population. Therefore, surveillance strategies and improved accuracy in diagnosis of clinically important pediatric varicoceles prompting treatment are needed in the future.

Abstract
While varicocele is the most common cause of surgically correctable infertility in adult males, with repair resulting in improved semen parameters in 60% to 80% of men and a higher likelihood of conception in up to 60% of men, the rationale for varicocele repair in the pediatric population is less clear. Additionally, prepubertal varicoceles are much less common and their management is controversial. Adolescents with a varicocele are often in the midst of a progressive disease process. Despite the high prevalence of varicocele and its association with progressive disease processes, the indications for adolescent varicocele repair and the effects thereof on paternity have been persistently challenging to study. This review will briefly present some of the current issues regarding adolescent varicocele from a pediatric urological point of view, including the evaluation of adolescent varicocele, the optimal surgical indications, the optimal choice of surgical intervention to be performed, and outcomes.

Abstract
Male infertility affects up to 12% of the world's male population and is linked to various environmental and medical conditions. Manual microscope-based testing and computer-assisted semen analysis (CASA) are the current standard methods to diagnose male infertility; however, these methods are labor-intensive, expensive, and laboratory-based. Cultural and socially dominated stigma against male infertility testing hinders a large number of men from getting tested for infertility, especially in resource-limited African countries. We describe the development and clinical testing of an automated smartphone-based semen analyzer designed for quantitative measurement of sperm concentration and motility for point-of-care male infertility screening. Using a total of 350 clinical semen specimens at a fertility clinic, we have shown that our assay can analyze an unwashed, unprocessed liquefied semen sample with <5-s mean processing time and provide the user a semen quality evaluation based on the World Health Organization (WHO) guidelines with ~98% accuracy. The work suggests that the integration of microfluidics, optical sensing accessories, and advances in consumer electronics, particularly smartphone capabilities, can make remote semen quality testing accessible to people in both developed and developing countries who have access to smartphones.

Abstract
Varicocele is characterized by elongation, dilatation, and tortuosity of the veins draining the testis and its covers, causing circulatory reflux along the inner spermatic vein [ 1 ]. Varicocele results in progressive testicular lesions and, if untreated, can lead to testicular atrophy [ 2 ]. Varicocele is considered the most frequently identified cause of male infertility [ 3 ]. The mechanisms involved in varicocele formation are not well known and probably are multiple, differing from one patient to another.

Abstract
INTRODUCTION In the 1970s, Tauber described the antegrade sclerotherapy technique to treat varicoceles, and reported a 10% recurrence rate. The present study aimed to evaluate paediatric success rates and the effect of modifications to the surgical technique. METHODS A prospective study was performed of all adolescent patients undergoing antegrade sclerotherapy surgery. Each patient had an idiopathic varicocele with spontaneous venous reflux on Doppler examination, and underwent cannulation of a pampiniform plexus vein via a scrotal incision under general anaesthetic. Aethoxysklerol® 3% (2 ml/kg) maximum 3 ml was injected into the pampiniform plexus vein under fluoroscopic monitoring. Success was assessed by clinical examination and Doppler ultrasound 3, 6 and 9 months after surgery. Data were presented as median (interquartile range). Patients were split into three groups: Group A - liquid sclerotherapy with Y connector; Group B - liquid sclerotherapy direct to cannula; and Group C - foam sclerotherapy direct to cannula. Fisher's exact test was used to compare the success rates in each group. RESULTS A total of 91 patients underwent antegrade sclerotherapy. The median age was 14.8 years (range 13.7-15.5). Eleven persistent varicoceles occurred and were diagnosed by Doppler ultrasound. The success rate of surgery was 58% in Group A, 90% in Group B and 96% in Group C. Success was significantly higher in Group B and Group C compared with Group A. No testicular atrophy occurred; two wound infections, two haematomas and one hydrocele were recorded (Table). CONCLUSION Introduction of antegrade sclerotherapy in the adolescent population resulted in a safe and cost-effective method for the management of adolescent varicocele. Several modifications to the technique have been introduced to achieve a high success rate (96%) with minimal complications.

Abstract
The primary indication for varicocele repair in adults, that of failed paternity, must be substituted in the adolescent population with surrogate parameters of testicular size differential and semen analysis. Making recommendations based on these two parameters is incredibly difficult because studies often have contradictory findings, different patient populations, and lack of long-term follow up of the key endpoint, paternity. Therefore, it is not a surprise that recommendations for adolescent varicocele repair are general (with some exceptions) and necessarily so because of limitations in quality of evidence. Apart from pain, all indications for varicocele repair in adolescence remain controversial. This highlights the most important task for future studies: to prevent pediatric urologists from allowing a potentially damaging process to go untreated, while at the same time avoiding unnecessary intervention on a highly prevalent condition.

Abstract
Varicocele is commonly encountered in adolescents. There are still many controversies regarding pathophysiology, health effects, clinical significance, and optimum treatment of this condition. This article reviews the current evidence pertaining to children and adolescents with varicocele. This group present a unique and somehow challenging situation, since they are still going through pubertal changes that may confound the effects of the disease and its treatment on the developing testes.

Abstract
INTRODUCTION Adolescent males with varicoceles present a dilemma for surveillance and treatment. Testicular volumetrics have not been shown to predict SA outcomes. Serial SAs are thus recommended in asymptomatic adolescent males with varicoceles and normal testicular development, but the natural history of semen parameters is unknown. OBJECTIVE To explore the natural history of semen parameters in adolescent boys with a left varicocele under active surveillance. STUDY DESIGN Adolescents with an asymptomatic unilateral left varicocele, Tanner V development, normal testicular volumes, and an initial SA were retrospectively reviewed in a single-institution prospectively followed cohort. Total motile count (TMC) was calculated. A cutoff of TMC Z 20 million was used to dichotomize SA results into "normal" or "poor." Those with poor SA were offered repeat SA. Cumulative probabilities of normal TMC over successive rounds of SA were calculated. Bivariate models were used to explore associations of a second consecutive poor TMC with age and varicocele grade. RESULTS A total of 216 patients provided an initial SA between 1992 and 2015. We excluded 17 for a history of cryptorchidism or incomplete SA data for a final cohort of 199 patients with median follow-up of 3.3 years (interquartile range 1.5-5.6 years). The mean age at initial SA was 17.9 years (range 14.8-21.8 years). One hundred and nine out of 199 had an initial normal TMC. Of the 90 out of 199 with an initially poor TMC, 51 had repeat SA and 24 of the 51 patients improved to normal TMC. Of the 27 patients with two consecutive poor TMCs, 15 had a third SA and five out of 15 improved to normal TMC. Thus, cumulatively, 55%, 67%, and 69% of all patients had a normal TMC after an initial, second, and third SA, respectively. However, fewer patients in each round of SA normalized their TMC (Figure). Neither age nor varicocele grade was associated with a second consecutive poor TMC. DISCUSSION Two-thirds of Tanner V boys with an uncorrected varicocele and normal testicular volumes achieve a normal TMC regardless of varicocele grade or age. Despite Tanner V development, 47% with an initial "poor" SA will improve to normal status without surgery. However, a small subgroup of patients will have persistently poor TMC and thus should be targeted in future research for timely intervention. CONCLUSION Semen parameters improve over time. SA should be followed and repeated at least once in symptomatic Tanner V boys with varicoceles.

Abstract
Infants, children, and adolescents with inguinoscrotal pathology comprise a significant proportion of emergency department and outpatient visits. Visits to the emergency department primarily comprise individuals presenting with scrotal pain due to testicular torsion or torsion of the testicular appendages. At such time, immediate urological consultation is sought. Outpatient visits comprise those individuals with undescended testes, hydroceles, and varicoceles. Rare, but important problems, such as pediatric testicular tumours, may also present in the office setting. Many of these outpatient visits are to primary care physicians, who should have an appreciation of the timing and need for referral. The purpose of this review is to familiarize the general urologist and primary care physician with these varied pathologies and give insight into their assessment and management. Some of these same conditions are seen in adult patients, but there are some significant differences in their management in the pediatric group. In addition, the utility of imaging studies, such as ultrasound, are discussed within each pathological entity. It is hoped that this overview will assist our general urology and primary care colleagues in patient management for diverse inguinoscrotal pathologies.

Abstract
A varicocele is described as pathologically enlarged, tortuous veins of the pampiniform plexus, leading to an increased testicular temperature and adrenal metabolite reflux into the testes. Varicocele can impair spermatogenesis and is considered to be the most common cause of male infertility. Patients may palpate a thickening in the scrotum or complain of dull scrotal or inguinal pain, which increases when standing or during erection. In the case of a sudden onset of varicocele in elderly men, it is necessary to exclude renal tumor and extend diagnostic ultrasound with the assessment of the abdominal cavity. The diagnosis of varicocele is based on medical history and physical examination, which involves palpation and observation of the scrotum at rest and during the Valsalva maneuver. Ultrasound is the imaging method of choice. The width and the number of vessels in the pampiniform plexus as well as the evaluation and measurement of regurgitation during the Valsalva maneuver are typical parameters analyzed during ultrasound assessment. However, diagnostic ultrasound is still a controversial method due to numerous and often divergent classification systems for varicocele assessment as well as its poor correlation with clinical manifestations. As a result of introduction of clear ultrasound criteria as well as the development of elastography and nuclear magnetic resonance, diagnostic imaging can play an important role in assessing the risk of damage to the testicular parenchyma, qualifying patients for surgical treatment and predicting the effects of therapy.

Abstract
In the past, the indications for varicocelectomy are primarily for infertility with abnormal semen parameters, testicular hypotrophy/atrophy in adolescents, and/or pain. The surgical treatment of varicocele for hypogonadism is controversial and debated. Recently, multiple reports in the literature have suggested that varicocele is associated with hypogonadism and varicocele repair can increase testosterone levels. Men with hypogonadal symptoms should have at least two serum testosterone levels. Microsurgical varicocelectomy may be beneficial for men with clinically palpable varicoceles with documented hypogonadism. In this review, we summarize the most recent literature linking varicocele to hypogonadism and sexual dysfunction and the impact of repair on serum testosterone levels. We performed a search of the published English literature. The key words used were “varicocele and hypogonadism” and “varicocele surgery and testosterone.” We included published studies after 1998. We, also, evaluated the effect of surgery on the changes in the serum testosterone level regardless of the indication for the varicocele repair.

Abstract
A varicocele is defined as the abnormal dilation of the internal testicular vein and pampiniform venus plexus within the spermatic cord. If a semen analysis is not obtained from the adolescent male, in the absence of other symptoms, the main clinical indication used by many urologists to recommend repair is testicular atrophy. The varicocele may result in testicular damage in some males causing testicular atrophy with impaired sperm production and decreased Leydig cell function, while in other males the varicocele may seemingly cause no ill effects. In adult men, varicoceles are frequently present and surgically correctable, yet the measurable benefits of surgical repair are slight according to a Cochrane review. While occurring more commonly in infertile men than fertile men, only 20% of men with a documented varicocele will suffer from fertility problems. Most varicoceles found in adolescents are detected during a routine medical examination, and it is difficult to predict which adolescent presenting with a varicocele will ultimately show diminished testicular function in adolescence or adulthood. As in adults, the mainstay of treatment for varicocele in adolescents is surgical correction. However, unlike an adult varicocelectomy (the microsurgical approach is the most common), treatment for an adolescent varicocele is more often laparoscopic. Nevertheless, the goals of treatment are the same in the adolescent and adult patients. Controversy remains as to which patients to treat, when to initiate the treatment, and what type of treatment is the best. This review will present the current understanding of the etiology, diagnosis and treatment of the adolescent varicocele.

Abstract
A varicocele is an abnormal dilatation and tortuosity of the veins of the spermatic cord. Although varicoceles are common in the general population and are frequently found on routine physical examinations, they represent the most common correctable cause of male factor infertility. Varicoceles are also often incidental findings on imaging studies, particularly scrotal ultrasound. Importantly, not all varicoceles should be treated equally (or at all), and basic guidelines on the evaluation and indications for treatment of adult varicoceles should be reviewed before counseling and treatment. A semen analysis should be obtained for any male patient of reproductive age considering intervention. The adolescent varicocele is managed much differently than the adult varicocele and remains a source of controversy. This review describes the clinical presentation and the evaluation of adult and pediatric varicoceles, and provides guidance on their diagnosis and workup. It also describes options for surgical repair and the success and complication rates associated with each surgical approach, ultimately supporting microsurgical subinguinal varicocele repair as the current surgical standard.

Abstract
In recent years, there has been increasing interest in transitional urology, or how to best prepare patients with major congenital urologic diseases, such as bladder exstrophy and neuropathic bladder, to manage their own health care with adult urologists. However, common pediatric urologic conditions may be encountered by the adult urologist with more regularity. This review focuses on three relatively common conditions which may be identified in childhood, the consequences from which a patient may seek help from an adult urologist: cryptorchidism, varicocele, and Klinefelter syndrome.

Abstract
Objective of this retrospective study was to assess the presence and clinical grade of varicocele among Qatari and non-Qatari men evaluated for infertility. Diagnosis of varicocele was performed clinically and confirmed via colour Doppler ultrasonography. A total of 455 infertile male patients (mean age 36.3 ± 7.6 years) were divided into either Qatari (n = 91, mean age 37.3 ± 9.1 years) or non-Qatari (n = 364, mean age 36.0 ± 7.1 years) groups. Among all patients, 43.1% (n = 196) were confirmed to have varicocele, of which 40 were Qatari and 156 non-Qatari. Among all patients, 171 (37.6%) presented with left-sided varicocele and 25 (5.5%) with bilateral varicocele. Of the 196 patients with varicocele, grade I was given to 40 (20.4%), grade II to 68 (34.7%) and grade III to 88 (44.9%). Grade II and III varicocele were seen significantly more frequently than grade I among all patients and non-Qatari patients (p < .05). Grade II varicocele was seen more frequently than grades I or III among Qatari patients, but difference was not significant. Grade III was seen significantly more frequently than grade I among patients with secondary infertility (p < .05). Varicocele is an important health issue in Qatar among both Qatari and non-Qatari men.

Prognostic Predictors of Fertility in Young Adult Patients With Varicocele: Peak Retrograde Flow Velocity and Reflux Grade. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2016; 35:1241-1250.

Abstract
OBJECTIVES The purpose of this study was to determine prognostic factors affecting semen parameters in patients with varicocele during the postadolescent period. METHODS This study was approved by the Institutional Review Board. Between May 2013 and May 2015, we prospectively obtained demographic and sonographic data from postadolescent patients with varicocele. Potential risk factors affecting semen parameters, including age at diagnosis, height, weight, body mass index, varicocele laterality, varicocele grade, left testicular volume, right testicular volume, total testicular volume, testicular atrophy index, testicular volume differential, right and left maximum vein diameters, peak retrograde flow velocity, reflux flow volume, and reflux grade in both supine and standing positions, were recorded. RESULTS The left peak retrograde flow velocity, reflux flow volume, and reflux grade in the supine and standing positions, left testicular volume, right testicular volume, total testicular volume, and follicle-stimulating hormone level were found to be associated with abnormal semen parameters (P < .05). By multivariate analysis, the follicle-stimulating hormone level was associated with the sperm concentration and morphologic characteristics, and the left peak retrograde flow velocity in the standing position was associated with deterioration of sperm motility and morphologic characteristics. Additionally, the left reflux grade in the standing position was associated with the sperm concentration, and the left testis volume was associated with motility. CONCLUSIONS The left peak retrograde flow velocity and reflux grade in the standing position were significantly associated with all semen analysis parameters. This finding supports the use of testicular duplex Doppler sonography as a noninvasive tool for evaluation of testicular function in patients with varicocele and helps clinicians determine patients' fertility status.

Abstract
A systematic review was conducted to identify and qualitatively analyze the methods as well as recommendations of Clinical Practice Guidelines (CPG) and Best Practice Statements (BPS) concerning varicocele in the pediatric and adolescent population. An electronic search was performed with the MEDLINE, EMBASE, Science Direct, and Scielo databases, as well as guidelines' Web sites until September 2015. Four guidelines were included in the qualitative synthesis. In general, the recommendations provided by the CPG/BPS were consistent despite the existence of some gaps across the studies. The guidelines issued by the American Urological Association (AUA) and American Society for Reproductive Medicine (ASRM) did not provide evidence-based levels for the recommendations given. Most of the recommendations given by the European Association of Urology (EAU) and European Society of Pediatric Urology (ESPU) were derived from nonrandomized clinical trials, retrospective studies, and expert opinion. Among all CPG/BPS, only one was specifically designed for the pediatric population. The studied guidelines did not undertake independent cost-effectiveness and risk-benefit analysis. The main objectives of these guidelines were to translate the best evidence into practice and provide a framework of standardized care while maintaining clinical autonomy and physician judgment. However, the limitations identified in the CPG/BPS for the diagnosis and management of varicocele in children and adolescents indicate ample opportunities for research and future incorporation of higher quality standards in patient care.

Abstract
BACKGROUND The American Society for Reproductive Medicine Practice Committee recommends obtaining a semen analysis (SA) in pediatric patients presenting with a varicocele in the absence of significant testicular atrophy. Among infertile adults with a varicocele, surgery is indicated in the presence of abnormal semen analysis regardless of testicular atrophy. Despite these two statements, semen analysis is not widely utilized by pediatric urologists in the USA managing a patient with a varicocele. OBJECTIVE We explored the attitudes of patients, parents, and practitioners toward SA to identify potential barriers to the use of SA in the evaluation of the adolescent varicocele. STUDY DESIGN We conducted a survey of Society for Pediatric Urology members regarding their management of adolescent varicoceles, with focus on the utilization of SA. The survey consisted of 14 multiple choice questions and two open-ended questions regarding use of SA in practice, barriers to its use, indications for varicocelectomy, and demographics. We also surveyed patients presenting for initial evaluation of a varicocele, as well as their parents, regarding their knowledge about SA and their attitude towards obtaining it. Statistical analysis was performed (p < 0.05 significant). RESULTS The practitioner survey response rate was 53% (168). Only 13.1% routinely incorporated SA in their practice, with 48% of all responders having some degree of discomfort asking for a SA. Of practitioners who cited discomfort, 90% never order a SA for patients with varicoceles. From the 46% of physicians who ordered a SA, we noted significant practice variability (see Figure). The patient/parent survey demonstrated that this population was uncomfortable with the notion of obtaining a SA, with most patients/parents citing lack of knowledge about SA as the main barrier. Patient and parent knowledge was found to correlate. DISCUSSION This study uniquely addresses an issue that has not been discussed in the adolescent varicocele literature to date. It can increase awareness of the option of incorporating SA data in management of the adolescent who presents with a varicocele. CONCLUSION Recognizing and then breaking through the barriers to obtaining a SA, would improve patient care, providing a direct assessment of the impact of a varicocele on fertility potential and thus best determining which patients require surveillance versus surgical intervention. This study suggested that the barriers to SA are surmountable.

Abstract
A varicocele is defined as an abnormal dilatation of the pampiniform plexus of veins of the testis. The vast majority of children and adolescents with varicoceles have no subjective symptoms. The complete work-up of patient diagnosed with a varicocele involves a physical exam in supine and prone position with and without Valsalva, and the use of ultrasound to measure testicular volume and blood flow. Because of growth issues occurring during puberty and adolescence, serial follow-ups may be done to determine any detrimental change in testicular size and symptomatology. The main difference of an adolescent varicocele is the fact that semen parameters are unavailable and do not count for treatment strategy. In this review, the focus is made on a recent study that has evaluated the ultimate endpoint: paternity. It appears that screening and treatment of a varicocele in the adolescent period does not influence the ultimate chance of paternity.

Abstract
What to do with the adolescent varicocele? With merging the information obtained from an extensive review of the literature with our own clinical research, I believe that we already have knowledge enough to say that the adolescent with a varicocele often is in the midst of a progressive disease process. Strong evidence already exists that well more than the majority of Tanner 5 boys with a varicocele and 20% asymmetry will already have abnormally low total motile sperm counts (TMCs) and likely abnormally low sperm concentration as well. There are now many studies in addition to common sense to support the value of % asymmetry as a marker of future abnormal sperm parameters. While we know that some boys at lower Tanner stages who present with asymmetry will have catch-up growth during adolescence, we also know that almost all boys with 15% asymmetry or greater in conjunction with a Doppler detected peak retrograde flow (PRF) of 38 cm/s or greater will end up with greater than 20% asymmetry on follow-up. There also are some boys of concern with less asymmetry but instead have small testes bilaterally, perhaps as a result of the left varicocele slowing the growth of the right testicle and/or an associated undetected or overlooked palpable right varicocele that is also negatively affecting the right testicle. Fortunately, we now have another marker available, i.e., total testicular volume (TTV), to assist in decision making for the adolescent falling into this scenario. Once markers are in place in an early Tanner stage boy with a varicocele that indicate that abnormal semen parameters will likely be present when a Tanner 5 stage of development is reached, there is no reason to wait until the child is older so that a semen analysis can be comfortably requested for the documentation. One argument in favor of waiting is that abnormal semen parameters in a Tanner 5 male usually are reversible. However, how do we know that once abnormal parameters are reversed they then will stay normal in a testicle that already has incurred damage. In other words, I feel it is best to operate once the indicators are in place. We do not want to be suddenly surprised when that individual when older has difficulty fathering a child at a time in life when surgery might be too late to resolve what has taken years to develop. Within this manuscript I will try to document my reasons for the aforementioned rationale.

Abstract
INTRODUCTION Orchidometric evaluation of the testis has been proposed as a cost-effective alternative to measurement of the testis with high-frequency linear ultrasound, which may be costly in terms of hospital resources and patient time. It is known from animal experiments, autopsy series, and small clinical studies that, under ideal conditions, orchidometry may approximate ultrasound measurement. However, little is known of the effectiveness of orchidometry in the clinical setting in a large sample of adolescents with varicocele. OBJECTIVE We sought to analyze the performance characteristics of Rochester orchidometry and its agreement with ultrasound testis volumes in boys with varicocele. STUDY DESIGN Our institutional varicocele database was analyzed from March 2000 to May 2013, including all boys with Rochester orchidometric measurement and ultrasound-based volume measurement performed on the same day. The Lambert formula (L*W*H*0.71) was used to calculate ultrasound volumes. Seven-hundred and twenty measurements were included: 360 of the left testis, and 360 of the right testis. Each subject was included once; in the event of serial measurements the earliest measurement was analyzed. Bland-Altman plots with 95% limits of agreement were used to compare orchidometry and ultrasound measurements. Analysis was performed with JMP, v11 Pro. RESULTS Age at exam ranged from 11.2 to 18.5 years (median 15.8). With respect to varicocele grade, 183 (50.8%) were grade III, 113 (31.4%) were grade II, 42 (11.7%) were grade I, 12 (0.3%) were bilateral, and 10 (0.3%) were ungraded. Mean ultrasound left testis volume was 13.6 cc (SD 6.6) and mean right testis volume was 15.1 cc (SD 6.9). Eleven surgeons performed the orchidometric measurements; one surgeon performed 71% of the exams. Mean overestimation on the right was 2.0 cc (SD 4.2) and on the left was 1.9 cc (SD 4.1); each was highly statistically significant (p < 0.0001, paired t test). Error was correlated with testis size, implying a greater degree of overestimation with increasing volume (p < 0.01, Pearson's correlation 0.09). Amount of volume overestimation and variability was not significantly different for right and left testis. Sensitivity and specificity of Rochester orchidometry to detect a testis volume differential (TVD) of 20% were 33% (95% CI 23-42%) and 96% (95% CI 92-97%), respectively. Testis size, varicocele grade, or examining surgeon had no effect on sensitivity or specificity. DISCUSSION We have shown in a large series of boys with adolescent varicocele that in clinical practice there is a modest degree of overestimation of testis volume on average (1.9-2.0 cc), although there is a large range of volume estimation, such that the 95% confidence interval ranges are quite wide, from approximately 6 cc lower than the true volume to 10 cc greater than the true volume. Furthermore, the low sensitivity (33%) of orchidometry for 20% testis volume differential renders this a suboptimal screening tool for this clinical parameter, which has been shown to be associated with semen analysis outcomes. Knowledge of the performance characteristics of orchidometry is similarly important for research, as factors such as the prevalence of testis volume differential are then dependent on the modality of measurement. Lastly, that this was conducted over a long time course with several surgeons involved suggests that these data reflect real-world application of orchidometry. CONCLUSIONS Appropriate caution should be exercised when relying solely on orchidometric evaluation of the testis. Rochester orchidometry in general appears to overestimate testis size, and there is wide variability in the estimation. In clinical practice, the sensitivity of Rochester orchidometry is modest in detecting a 20% testis volume differential; this difference would be missed in approximately two out of three of boys screened with orchidometry alone.

Abstract
Adolescent varicocele is associated with ipsilateral testicular hypotrophy and the concern for future infertility. A testicular size discrepancy greater than 15-20 % between left and right testicle is an indication for treatment to allow catch-up growth in the hope of preventing a future decline in fertility. Some authors advocate for a period of watchful waiting, as normal testicular growth may occur asymmetrically. We review the current literature to highlight some controversies and challenges in management.

Abstract
PURPOSE Varicocele is one of the most common genital conditions referred to pediatric urologists. Most adolescents with varicocele are asymptomatic and their fertility future (and surgery benefit) is largely unknown. This review assesses varicocele evaluation, management and indications for repair, as well as types and success of varicocelectomy. MATERIALS AND METHODS A systematic literature review was performed on Embase™, PubMed® and Google Scholar™ for adolescent varicocele. Original research articles and relevant reviews were examined, and a synopsis of these data was generated for a comprehensive review of clinical adolescent varicocele management. RESULTS The prevalence of adolescent varicocele is similar to the adult population. While ultrasound is the most sensitive method for determining testicular volumes, orchidometer measurement may be adequate to gauge significant discordance. Significant hypotrophy of the affected testis with poor total testicular volume may indicate a testis at risk and warrant surgical repair. Similar findings have been noted with an associated high peak retrograde venous flow. Testicular hypotrophy often resolves following surgery but may also improve spontaneously if followed through adolescence. Continued scrotal pain despite adequate support or serial abnormal semen analysis in Tanner stage V boys is an indication for varicocelectomy. Artery and lymphatic sparing techniques (microscopic subinguinal or laparoscopic) are associated with the lowest risk of recurrence and complications. CONCLUSIONS Overtreatment and under treatment are medically and financially costly. Abnormal serial semen analysis with or without testicular hypotrophy is an indication for varicocele repair. If observation remains the treatment, followup with an adult urologist should be encouraged until paternity is achieved.
