Andrologia 2020; 52:e13583. [PMID: 32271466 DOI: 10.1111/and.13583] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 03/04/2020] [Accepted: 03/10/2020] [Indexed: 12/01/2022] Open
Abstract
This study aimed to search whether there is a link between reflux flow and hormonal profile. Data of 250 patients were retrospectively investigated. Pre-operative and 6th month semen analyses of these patients' results were compared with pre-operative and post-operative 6th month serum levels of testosterone. Based on the venous flow on pre-operative Doppler ultrasonography, patients were divided into two groups. Patients with a venous flow ≤4 s were assigned to Group 1 and those with a venous flow >4 s to Group 2. Venous reflux time cut-off was calculated as 4 s using ROC curve according to the increase in testosterone level. When venous reflux time was selected as approximately 4.0 s, ROC had 79.8% sensitivity and 72.8 specificity. The probability of a post-operative increase in testosterone is high in patients with a venous reflux time longer than 4 s.

Abstract
Objective: To study scrotal ultrasonographic characteristics in patients with subclinical varicocele (SV) and investigate their relationship with semen parameters. Patients and methods: In all, 56 men with SV were recruited and divided into two groups, according to their semen characteristics. Group A, comprised 34 men with normal semen analysis; and Group B, comprised 22 men who carried at least one abnormality, regarding sperm concentration, motility and morphology. Between the two groups we compared: age; body mass index (BMI); semen pH and semen volume; total testicular volume (TTV); maximal vein diameter (MVD) and degree of reflux; mean values of peak-systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) of the intratesticular arteries; whether bilateral SV; and serum testosterone and follicle-stimulating hormone (FSH) levels. Results: Asthenospermia was present in all patients in Group B; 10 patients had asthenospermia only, six patients were astheno-oligospermic and six patients had astheno-oligo-teratospermia. Age, BMI, semen pH and volume, TTV, MVD and degree of reflux did not differ significantly between the two groups (P > 0.05). However, EDV, PSV and RI were significantly different (P < 0.05). Bilateral SV was significantly more frequent in patients in Group B (P < 0.05). Finally, FSH was elevated in Group B (P < 0.05), whereas testosterone was normal in both groups, albeit significantly lower in men with abnormal semen analyses (P < 0.05). Conclusion: Classic ultrasonographic characteristics in men with SV, such as venous size or degree of reflux, were insufficient to distinguish patients with abnormal semen analysis. However, bilateral disease and intratesticular haemodynamics differed significantly in patients with SV and abnormal semen analysis. Abbreviations: BMI: body mass index; CDU: colour Doppler ultrasonography; EDV: end-diastolic velocity; MVD: maximal vein diameter; PSV: peak-systolic velocity; RI: resistive index; SV: subclinical varicocele; TTV: total testicular volume; US: ultrasonography

Abstract
OBJECTIVES To evaluate testes in patients with varicocele using real-time strain elastography and to correlate the results with the patients' clinical, seminal, and hormonal profiles. METHODS Fifty patients with left varicocele and 20 age-matched control participants were included in the study. All participants were evaluated via a historical interview, clinical examination, including testicular volume and varicocele grade, hormonal assay (total and free testosterone, luteinizing hormone, and follicle-stimulating hormone), computer-assisted semen analysis, and testicular assessment using real-time strain elastography to define the strain ratio and elasticity score. RESULTS Testicular volume and sperm parameters were significantly lower (P < .001), whereas the follicle-stimulating hormone level, strain ratio, and elasticity score were significantly higher (P < .01; P < .001; P < .001, respectively), in the varicocele group. Other hormone levels in the endocrine profile were not significantly different between the groups. Significant negative correlations were found between the elasticity score and testicular volume and the percentage of normal forms (P = .029; P = .005). The varicocele grade showed significant positive correlations with both the strain ratio and elasticity score (P < .001). CONCLUSIONS Strong correlations were found between real-time strain elastography and the testicular volume, varicocele grade, and sperm morphologic characteristics. Real-time strain elastography is a simple, noninvasive investigative modality that can potentially be used to study the structure and function of the testicular tissue in varicocele.

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.

Does varicocelectomy improve semen analysis outcomes in adolescents without testicular asymmetry? J Pediatr Urol 2017; 13:76.e1-76.e5. [PMID: 27818033 PMCID: PMC5329071 DOI: 10.1016/j.jpurol.2016.09.010] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Accepted: 09/16/2016] [Indexed: 11/24/2022]
Abstract
PURPOSE The main indications for adolescent varicocelectomy are testicular hypotrophy or pain. However, we have previously shown that both serial total testicular volume and volume differential are weakly associated with semen quality. The ultimate patient goal is paternity, but semen analysis is critical to appropriate management of varicocele. We hypothesize that varicocelectomy improves total motile count (TMC) among patients who only have abnormal semen analysis (SA) parameters, but not among those with potential hormonal dysfunction such as Klinefelter syndrome or cryptorchidism. METHODS We retrospectively reviewed our registry of adolescent males followed with a clinical left varicocele. For this study, subjects without sustained testicular asymmetry, who were Tanner V, and gave at least one preoperative SA were included. Subjects were excluded if they had embolization for their varicocele or no postoperative SA. Primary outcome was change in TMC before and after surgery, compared using the Wilcoxon signed rank test after stratifying by surgical indication. Secondary outcomes included rates of improved TMC and normalized TMC (>20 million) after surgery, compared across covariates using the Fisher exact test. RESULTS Seventeen patients met the eligibility criteria, 11 of whom underwent repair for only abnormal preoperative TMC. Overall, median age (interquartile range [IQR]) at first preoperative SA was 17.6 (15.9-17.9) years. The median preoperative TMC across all SA was 2.8 (0.7-7.4) million. The median age at surgery was 18.2 (16.8-18.9) years. Postoperatively, the median TMC across all SA increased to 18.2 (3.6-18.2) million (Wilcoxon signed rank test, p < 0.01; see Figure). The improvement in TMC occurred primarily in the group who only had abnormal preoperative TMC (82% improved, 55% normalized); lack of improvement was seen in patients who had a history of Klinefelter or orchiopexy for cryptorchidism. CONCLUSIONS Adolescent varicocele patients should undergo SA after development of Tanner V. Varicocelectomy has a high success rate for improving TMC in adolescent or young adult males who only have abnormal TMC and no history of cryptorchidism.

Abstract
Varicocele is the most common surgically treatable cause of male infertility, and often results in alterations in semen parameters, sperm DNA damage, and changes to the seminal milieu. Varicocele repair can result in improvement in these parameters in the majority of men with clinical varicocele; data supporting repair in men with subclinical varicocele are less definitive. In couples seeking fertility using assisted reproductive technologies (ARTs), varicocele repair may offer improvement in semen parameters and sperm health that can increase the likelihood of successful fertilization using techniques such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), or may decrease the level of ART needed to achieve successful pregnancy. Male infertility is an indicator of general male health, and evaluation of the infertile male with an eye toward future health can facilitate optimal screening and treatment of these men. Furthermore, varicocele may represent a progressive lesion, offering an argument for its repair, although this is currently unclear.

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
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
OBJECTIVE To investigate the outcome of varicocelectomy based on the duration of venous reflux (DVR) of the pampiniform plexus veins. MATERIALS AND METHODS In total, 138 patients with clinically palpable varicoceles were evaluated for DVR with color Doppler ultrasonography from May 2009 to August 2014. The DVR was defined as the DVR of a varicocele in the supine position during the Valsalva maneuver. Patients with bilateral, recurrent, or subclinical varicoceles; hormonal imbalances involving follicle-stimulating hormone, luteinizing hormone, or total testosterone; azoospermia; and intraoperative or postoperative complications were excluded. Of the 138 patients, 76 met the inclusion criteria. All patients were treated with subinguinal microscopic varicocelectomy. Restoration of all three semen parameters (concentration, motility, and morphology) to normal values 6 months postoperatively was considered to indicate treatment success. The patients were divided into those with a DVR of <4.5 seconds (Group 1) and ≥4.5 seconds (Group 2). RESULTS The mean age of the patients was 29.39 (±6.03) years. No statistically significant relationship was found between the success rate and varicocele grade. The cutoff DVR value was calculated as 4.5 seconds using a receiver operating characteristics curve according to patients who underwent successful treatment. The success rates of Groups 1 and 2 were 40.0% and 88.2%, respectively (P = .0001). CONCLUSION The results of this analysis indicate that a DVR of ≥4.5 seconds predicts better outcomes of varicocelectomy.

Abstract
Varicocele is frequent but correctable cause of male infertility. Varicocelectomy is the most commonly performed operative procedure for varicocele. Majority of varicocele patients do not have fertility problem, therefore surgical correction is not recommended in all prevalent cases. On the other hand, varicocele is a progressive condition in some cases and individual with varicocele is at risk for developing impairment which can ultimately lead to semen deterioration and consequent infertility. Selection of patients with varicocele that will progress and cause infertility is beyond our current diagnostic capabilities. Diagnostic assessment of varicocele depends on physical examination and scrotal ultrasound/doppler. Infrared digital thermography of scrotum is a non-invasive and objective diagnostic method for early varicocele detection by means of temperature measurement on the scrotal skin surface. The criteria for diagnostic use of scrotal thermography were recently presented. We hypothesize that the infrared digital thermography of scrotum could be the cornerstone in detection of varicoceles that tend to progress with impairment of semen quality and will require surgical correction, among all prevalent varicocele cases.
