Abstract
ABSTARCT Varicocele has a prevalence of 15% in the population and represents a primary cause of infertility in 40% of cases and a secondary cause in approximately 80% of cases. It is considered the major correctable cause of male infertility. Despite its high prevalence in the infertile population, a large number of patients with varicocele do not experience reproductive difficulties. For this reason, it is still highly debated which parameters could be used to predict which patients with varicocele will be most likely to benefit from its repair. The main international and European guidelines state that treatment should only be considered in infertile patients with abnormal sperm quality. However, these guidelines do not help physicians to identify which of these patients may benefit from the treatment. Therefore, this narrative review collects the evidence in the literature on the usefulness of some factors as predictors of improvement, highlighting how some of them may be effective in an initial selection of patients to be treated, while others are promising but further studies are needed. Finally, a brief consideration on the possible role of artificial intelligence is proposed.

Abstract
Objective The goal of this work was to evaluate if men who underwent microsurgical varicocelectomy would have improvement in serum testosterone (T) as well as serum 17-hydroxyprogesterone (17-OHP-An intratesticular T biomarker) in addition to semen parameters after operation. Materials and Methods We conducted a prospective analysis of 30 men who underwent microsurgical varicocelectomy from December 2018 to September 2019. We assessed varicocele grade and laterality, serum T, serum 17-OHP, serum follicle- stimulating hormone (FSH), serum LH, and semen parameters in baseline and follow-up. According to the data distribution, we reported the median and interquartile ranges and utilized the Mann-Whitney U, Student's t test and Wilcoxon rank test. Correlation analysis was performed with the Spearman test. Results In the baseline, 9 (30%) men had 17-OHP < 55 ng/dL and 21 (70%) men presented with 17-OHP > 55 ng/dL. Also, 19 men had TMSC < 9 million, including 6 men with azoospermia, 1 man with cryptozoospermia, and 11 men with TMSC > 9 million. We found an improvement in most SA parameters of most men, which include concentration (63.3%, 19/30), motility (46.6%, 14/30), and TMSC (60%, 18/30). About seven (36.8%) men had TMSC upgraded to > 9. There was a significant change in volume (2.1 [1.5-2.8] to 2.4 [1.7-3.6] cc, P = .018), concentration (6.8 [0.8-22.5] to 12.5 [1-31] million/cc, P = .047) and TMSC (4.4 [0.3-15.1] to 10.5 [0-41.8] million, P = .012) after surgery. We neither found a change in serum T nor a change in intratesticular T (serum 17-OHP) after varicocelectomy (P > .05). FSH, LH and T were similar both before and after varicocelectomy (P > .05). Conclusion Despite improvement in semen parameters following varicocelectomy, we did not see changes in either serum or intratesticular T. This suggests that improvement of semen parameters following varicocele repair could be from factors other than changes in androgen levels within the testis.

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
PURPOSE Varicocele is defined as a state of varicosity and tortuosity of the pampiniform plexus around the testis caused by retrograde blood flow through the internal spermatic vein. The prevalence of clinically relevant varicocele ranges from 5 to 20% in the male population and is often associated with infertility and reduction of sperm quality. In this review, the pathophysiology and clinical aspects of varicocele are reviewed along with therapeutic options and treatment effects on sperm parameters and fertility both in adult and in pediatric/adolescent subjects. METHODS We conducted a Medline and a PubMed search from 1965 to 2018 to identify publications related to varicocele clinical aspects, treatment procedures and treatment outcomes. Keywords used for the search were: "varicocele", "varicocelectomy", "sclerotherapy", "male infertility", "subfertility", and "semen abnormalities". RESULTS Data from a large number of studies in adolescent and adult males indicate that varicocele correction improves semen parameters in the majority of patients, reducing oxidative stress and improving sperm nuclear DNA integrity either with surgical or percutaneous approach. CONCLUSIONS Varicocele repair seems to represent a cost-effective therapeutic option for all males (both adolescent and adults) with a clinical varicocele in the presence of testicular hypotrophy, worsening sperm alterations or infertility. On the other hand, some investigators questioned the role of varicocelectomy in the era of assisted reproduction. Thus, a better understanding of the pathophysiology of varicocele-associated male subfertility is of paramount importance to elucidating the deleterious effects of varicocele on spermatogenesis and possibly formulating new treatment strategies.

Abstract
Background The main purpose of this study is to evaluate the effects of varicocelectomy on serum testosterone levels and semen quality in infertile men who suffer from varicocele. MATERIALS AND METHODS This prospective study enrolled 115 subjects with clinical varicocele grades II and III and 240 fertile men as the control group. Total volume of testosterone serum level (ng/dl) and semen quality were compared before and after microscopic varicocelectomy. We normalized testosterone serum levels for age, grade, and testis size basis. SPSS 20 software was used to analyze the data. All results of continuous variables were reported as mean ± SD. Statistical significance was set at a P<0.05. RESULTS The mean ages of individuals who participated in the treatment (32.2 ± 5.23) and control (32.8 ± 5.27) groups were similar. There were similar mean values for adjusted testosterone levels between the varicocele (567 ± 222 ng/ml) and control (583 ± 263 ng/ml) groups. In the varicocele group, the adjusted testosterone levels insignificantly increased to 594 ± 243 ng/ml. Among semen parameters, only mean sperm concentration significantly increased after varicocelectomy. CONCLUSION Despite increases in sperm concentration, adjusted testosterone levels did not significantly improve after varicocelectomy.

Abstract
Current guidelines suggest that treatment of varicocele should be considered in patients with clinically palpable disease and abnormal semen parameters. However, the clinicians are often challenged with the decision whether to treat varicocele in patients with testicular pain or low testosterone levels. Moreover, varicocele is highly associated with DNA fragmentation due to the oxidative stress and it has been demonstrated that surgical repair of varicocele ameliorates oxidative stress markers and consequently the sperm DNA integrity. These new markers could have an adjunctive role to standard semen parameters especially when normal semen analysis is found in adult men with conventional methods. This review presents a contemporary overview of the rationale for varicocele treatment, as well as of the relationship between varicocele and other novel parameters such as DNA fragmentation index and reactive oxygen species. We will also discuss data from several recent series demonstrating that surgical treatment and especially microsurgical approach could resolve testicular pain, increase testosterone levels and fertility rate both in patients with non-obstructive azoospermia as well as in normozoospermia men. The correlation with progressive testicular failure will be also examined. We hope that this overview will provide clinicians with an evidence-based approach to managing these unanswered and conflicting topics.

Abstract
Varicocele is most often surgically repaired due to male infertility, however, has recently been linked to low serum testosterone. This paper serves to review the current literature regarding varicocele and its subsequent repair on serum testosterone. Twenty-eight human studies were identified with fifteen showing improved serum testosterone after repair. The majority of the studies that demonstrated improvement had preoperative testosterone levels that were low or below normal. Additionally, multiple well-designed studies with control groups not undergoing surgical repair demonstrated significant difference between groups. This improvement was less observed in studies with normal preoperative serum testosterone. A majority of these patients studied were presenting for infertility. It remains to be determined if these findings can be reproduced in men without infertility. The findings suggest that microsurgical varicocele repair can improve serum testosterone in men with low levels preoperatively in appropriately counseled men. It remains to be seen whether varicocele repair can help prevent the development of low testosterone in the future or which patients are at risk of developing low testosterone due to varicocele.

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
Testicular varicocele, which is defined as the dilation of the veins draining the testicle, has long been associated with a detrimental effect on testicular function. Despite a lack of high-quality, prospective data, recent evidence has shed light on potential links between varicocele and male infertility and serum testosterone levels. Similarly, varicocele repair has increasingly been shown to have a beneficial impact on pregnancy rates, semen parameters, and on improving serum testosterone in adult men. Numerous studies have assessed the optimal technique for varicocele repair and the bulk of the evidence has shown the microsurgical inguinal/subinguinal approach to have the highest success rates, the lowest overall complication rates, and the lowest recurrence rates. The management of varicocele in adolescents remains a clinical conundrum, but contemporary evidence suggests early deleterious effects of varicocele on testicular function in some patients. Well-designed prospective trials are critical to delineate the true impact and role of varicocele repair on male infertility and hypogonadism in adult and adolescent men.

Abstract
Varicocele is a well-established cause of male subfertility, which is directly proportional to its clinical grade. Although newer ultrasonic grading systems have taken into account the existence of pampiniform venous plexi, little is known about the clinical significance of the number of veins ligated during surgery. Very few undersized studies reported an influence which triggered the need to evaluate such association. This is a retrospective study of 378 patients who underwent left microsurgical subinguinal varicocoelectomy. Semen analyses and blood hormone studies performed pre-operatively were compared to those executed 6 months after surgery. Patients were divided into abnormal semen and normal semen groups based on their initial semen results. They were also subdivided according to the number of veins ligated intraoperatively into three groups: <5, 5-10, and >10 veins. Sperm count, total motility, and progressive motility were significantly increased in 62, 60.3, and 53.3% of patients post-operatively (p = 0.001), respectively. No significant differences in hormone levels were detected overall. Of the 378 patients, 332 had an abnormal semen analysis, while the remaining 46 patients had a normal result. Sperm count, total motility, and progressive motility significantly increased after varicocoelectomy in patients with an abnormal initial semen analysis (p = 0.001). In 48.7% of patients, 5-10 veins were ligated during surgery, whereas 28.3% had >10 and 23% had <5 ligated veins. No statistically significant differences were noted in the initial or the follow-up results among the number of vein subgroups. Varicocele ligation improves patients' fertility potential. This improvement, however, is not influenced by the number of veins ligated intraoperatively. Clinical grading maintains its superiority in the evaluation of varicocele patients.

Abstract
Testicular varicocele, a dilation of the veins of the pampiniform plexus thought to increase testicular temperature via venous congestion, is commonly associated with male infertility. Significant study has clarified the negative impact of varicocele on semen parameters and more recent work has shed light on its detrimental effects on the molecular and ultrastructural features of sperm and the testicular microenvironment, as well as more clearly defined the positive impacts of treatment on couples’ fertility. The relationship between varicocele and testicular endocrine function, while known for some time based on histologic evaluation, has become more apparent in the clinical setting with a growing link between varicocele and hypogonadism. Finally, in the pediatric setting, while future study will clarify the impact of varicocele on fertility and testicular function, recent work supports a parallel effect of varicocele in adolescents and adults, suggesting a re-evaluation of current treatment approaches in light of the progressive nature of the condition and potential increased risk of future disease.

Abstract
INTRODUCTION We aim to predict results of varicocelectomy on sperm density and progressive motility using preoperative clinical, laboratory and radiological data and to propose cut-off values for significant parameters. METHODS This prospective study was carried out between July 2011 and June 2014. We included 123 patients in our study. They were diagnosed with primary infertility with varicocele, were scheduled for varicocelectomy, and completed their follow-up. We excluded patients with azoospermia, total necrospermia, recurrent varicocele, and pituitary hormonal abnormalities. Varicocele was diagnosed and graded by physical examination and colour Doppler ultrasound. Semen analyses were completed preoperatively and 6 months postoperatively. Microscopic subinguinal varicocelectomy was done in all cases. Patient demographics, pre- and postoperative clinical data (varicocele grade and semen parameters) were statistically analyzed. RESULTS The mean ± standard deviation of age, body mass index, and subfertility duration was 28.3 ± 7.4 years, 29.1 ± 2.7 kg/m(2), and 21.9 ± 7.1 months, respectively. About 53% of our patients (n = 66) had bilateral varicocele, and unilateral disease was found in the other 57 (46.3%) cases. Varicocele grade I was diagnosed in 42 (34.1%) patients, while the other 81 (65.9%) patients had grade II or III. Higher grades of varicocele, preoperative total testosterone level, sperm density, and progressive motility had a statistically significant impact on the outcome of varicocelectomy in univariate testing. Multivariate logistic analysis revealed that grade of preoperative varicocele (95% confidence interval [CI] 5.6-6.3, p = 0.007) and sperm density (95% CI 2.7-1.6, p = 0.0035), and progressive motility (95% CI 1.1-2.3, p = 0.0123) are independent predictors of semen parameters improvement after varicocelectomy. CONCLUSION The grade of the varicocele, sperm density, and progressive motility are major predictors of outcome in varicocelectomy. Cut-off values of >8 million/mL and >18% for sperm density and progressive motility, respectively, in men with varicocele grade II or III, indicate a successful outcome.

Abstract
OBJECTIVE To investigate the relationship between testicular volume and semen parameter sin patients with unilateral high grade left varicocele. MATERIAL AND METHODS One hundred eighty seven patients who had left high grade varicocele aged 19-to-25 years were included in this study. All patients underwent a standard evaluation, including medical history and physical examination. The percentage testicular volume difference between the right and left testicles was calculated. The patients were divided into the following three groups; Group 1 (n=72) testicular volume difference <10%, testicular volume difference 10%-20% Group 2 (n=74) and testicular volume difference >20% Group 3 (n=41). RESULTS The mean age and BMI of the patients were 21.5 years and 23.1kg/m(2), respectively (P=.596, P=.943). The semen parameters and testicular volumes of the three groups were compared. The total motile sperm count, percentage of motile sperm, percentage of normal morphology sperm were found to be lower in Group 3 (P=.011, P=.012, P=.029 respectively). The mean testicular volumes for the left and the right testis were found to be 15.2cm(3) and 17.7cm(3) (P<.001), respectively. No significant difference was found in the right testicular volumes between groups (17.4, 17.7 and 18.1cm(3), P=.573). CONCLUSIONS A high grade left testicular varicocele is associated with ipsilateral testicular hypotrophy and parallel to worsened sperm parameters.

Abstract
Varicocele is present in 15% to 20% of the general population, but in approximately 35% to 40% of males presenting for an evaluation of their infertility. Indeed it is well known that varicocele can cause testicular damage and infertility. No evidence indicates a varicocele treatment in infertile men who have normal semen analysis or in men with subclinical varicocele. In this situation, varicocelectomy cannot be recommended. Varicocele repair may be effective in men with subnormal semen analysis, a clinical varicocele and otherwise unexplained infertility, but we need further randomized studies to confirm that this subgroup of infertile couples will benefit from treatment. There is no doubt about the standard indications of varicocelectomy, but recent literature seems to go towards new indications of varicocele repair. The aim of this review is to give a look at the literature to analyze the proper indications to varicocelectomy for the proper patient.

Abstract
PURPOSE To determine whether it is necessary to analyze the semen of varicocele patients in their early 20s who are not complaining of infertility. MATERIALS AND METHODS Data was collected retrospectively from 128 men with varicocele with no complaint of infertility, but with complaints of pain/discomfort or a mass/swelling during a 4-year period beginning in January 2009. The varicocele cases were matched 4 : 1 by age to 32 hemospermia controls. RESULTS The median patient age was 22.0 years in the case group and 24.0 years in the control group. The median values of the percentage of normal motility, normal morphology, and density in the case group were 42.5%, 40.0%, and 51.0×10(6)/mL, respectively. The median serum testosterone level was 4.2 ng/mL and 7.0% of the total patients had low serum testosterone levels in the case group. The number of patients with asthenospermia (17.2%), oligospermia (10.9%), and teratospermia (5.5%), and those with at least one abnormal semen parameter (19.5%) was significantly higher in the case group than the control group. The median values of the motility, morphology, and density of the case group were significantly lower than those of the control group. The multivariate analysis showed that patient characteristics (age, presence of pain, duration of symptoms, and grade of varicocele) cannot help to predict abnormal semen parameters (asthenospermia, oligospermia, teratospermia, or cases of at least 1 abnormal semen parameter) or serum testosterone levels <3.0 ng/mL. CONCLUSIONS Semen analysis is required as a screening test for semen abnormalities regardless of the chief complaint in varicocele patients in their early 20s.

Abstract
Varicocele is a relatively common condition that can impact men’s health in various ways. Unfortunately, its prevalence and the availability of various different methods of repairing it might lead to unnecessary treatment. An understanding of the various ways that this condition can impact men’s health is necessary in order to manage it appropriately. At present, there is substantial evidence to support varicocele repair in men who present with infertility, abnormal semen parameters, clinical varicocele and a female partner with normal fertility (or one with a potentially correctable abnormality). Varicocele repair appears to improve seminal fluid quality and might improve pregnancy rates. It might also have a role in managing men with non-obstructive azoospermia. Varicocele can also be a cause of scrotal pain that is usually of a dull character. Varicocele repair is an effective method of managing this type of pain, especially once proper measures have been taken to exclude other possible causes of orchalgia. Conservative measures are generally not effective in managing varicocele-related scrotal pain. There is growing evidence to suggest that varicocele repair might have a role in improving the serum testosterone level in men with hypogonadism, especially in the subfertile population. Well-designed prospective studies are needed to support the utilization of varicocele repair in managing these patients, as well as in preventing testicular dysfunction on a prophylactic basis.

Abstract
Varicocele has been implicated as a cause in 35%-50% of patients with primary infertility and up to 81% of men with secondary infertility. Although a large number of reports have shown improvement in the semen parameters after correction of varicocele, other studies have suggested no benefit. We report the first case of azoospermia after surgery in a young infertile male patient with left-sided varicocele and severe oligozoospermia undergoing laparoscopic varicocelectomy. A pregnancy was only achieved with assisted reproductive technology because semen cryopreservation was performed before surgery. In the light of the above, the deterioration of sperm count after varicocele repair in patients with severe oligozoospermia could be due to irreversible impairment of spermatogenesis of such patients, together with the possible temporary damage of the surgical repair. This possible complication could therefore turn the severe oligozoospermia into an indication to perform cryopreservation before surgery, on both clinical and medico-legal grounds. Further research is needed before drawing definitive conclusions regarding the management of varicocele-related severe oligozoospermia.

Abstract
The most common cause of male infertility is varicocele, and varicocele is the most common correctable cause of male factor infertility. In this article we reviewed the concept of varicocele in terms of its diagnosis, method of treatment, indications for treatment, treatment outcomes, and prognostic factors. Physical examination is an essential diagnostic tool in the evaluation of a patient with a varicocele. However, as it depends on subjective findings, standardization of the physical examination method is needed. Various methods for treatment of varicocele exist, including open surgical, laparoscopic, microscopic surgical, and radiologic treatment such as embolization. Among these treatment approaches, microscopic inguinal or subinguinal varicocelectomy has superior outcomes, with a low complication rate. The influence of the treatment of varicocele on fertility is still a controversial issue and a difficult question to address, because there are limitations to performing a randomized control study, and previous studies had a heterogeneity of subjects and high dropout rate. However, there is robust evidence that varicocelectomy improves semen parameters as a surrogate marker of the potential for fertility. To date, general indications for treatment of varicocele are limited in patients with proven infertility, clinical palpable varicocele, and abnormal semen characteristics. Recently, it was shown that some symptoms other than infertility could be an indication for varicocelectomy because these symptoms are frequently related to deterioration of semen parameters. Varicocele in the adolescent presents a more difficult decision regarding whether to treat. A testicular size discrepancy of more than 20% is helpful for treatment decisions. Various prognostic factors were noted in several studies without, however, a consistent consensus.

Abstract
Varicocele, the leading cause of male infertility, can impair spermatogenesis through several pathophysiological mechanisms. Of these, current evidence suggests that oxidative stress is the central element contributing to infertility in men with varicocele, to which the testis responds by way of heat stress, ischaemia or production of vasodilators, such as nitric oxide. Surgical varicocele repair (varicocelectomy) is beneficial not only for alleviating oxidative stress-associated infertility, but also for preventing and protecting against the progressive character of varicocele and its consequent upregulations of systemic oxidative stress. However, antioxidant therapy in infertile men with surgically treated and those with untreated varicocele is poorly studied, and well-designed trials are needed.

Abstract
OBJECTIVES To determine the effect of surgical varicocele repair in improving testicular Leydig cell function as shown by increased testosterone production. METHODS Eligible studies were searched in Medline and the Pubmed database, and cross-referenced as of 31 May 2011 using the terms "varicocele,""testosterone" and "surgery." The database search, quality assessment and data extraction were independently carried out by two reviewers. Only studies including patients with testosterone evaluation before and after surgery were considered for the analysis. A systematic review and meta-analysis was carried out for continues variables using random effect models. RESULTS Out of 125 studies, a total of nine were selected, including 814 patients. The combined analysis showed that mean serum testosterone levels after surgical treatment increased by 97.48 ng/dL (95% confidence interval 43.73-151.22, P=0.0004) compared with preoperative levels. CONCLUSIONS Surgical treatment of varicocele significantly increases testosterone production and improves testicular Leydig cell function.

Abstract
PURPOSE OF REVIEW To review the role of varicocele repair in the treatment of male infertility. RECENT FINDINGS Since the advent of technologies bypassing boundaries of natural selection, this question may seem outdated. Over the past 20 years, fertility has decreased, and testicular damage (cryptorchidism, tumors) has increased. Thus the exploration of the infertile male is still unavoidable. However, what should be done and assigned to the discovery of a varicocele?The issue raised is whether varicocele found during the review of the infertile couple should be treated or 'ignored'.This study will update significant findings with regards to the pathophysiology of varicocele-induced infertility, such as oxidative stress and role of varicocele in bilaterality of testicular damage. Benefits of varicocele repair in semen analysis and simplifications of assisted reproductive techniques are reported. But reviews of randomized clinical trials have raised doubts about the benefit of varicocele treatment in infertile men. SUMMARY We conclude that varicocele repair may be effective in men with subnormal semen analysis, a clinical varicocele and otherwise unexplained infertility. Deleterious cofactors, like obesity or smoking, could also be reduced for the benefit of general health and fertility.

Abstract
Background The effectiveness of varicocelectomy in restoration of fertility and improvement of semen parameters is still controversial. The purpose of this study was to determine the effect of age on semen parameters following varicocelectomy in a group of infertile men. Methods Improvements in sperm count, morphology, and motility were studied in 67 infertile patients 4–10 months after varicocelectomy. Results The mean age of the patients was 30.48 ± 7.49 years. Significant improvements in total sperm count, percentage normal morphology, and motility were noted in all age groups (P < 0.05). Patients aged <25 years demonstrated the greatest increase in sperm counts, normal morphology, and motility following varicocelectomy. There was a significant negative correlation between age and sperm count, sperm morphology, and sperm motility (P < 0.05). Conclusion The effect of age on improvement in sperm parameters after varicocelectomy is inconsistent with some reports in the literature, and could be attributable to the duration of infertility prior to surgery; in the long term, varicoceles are known to have deleterious effects on testis biology.

Abstract
This work aimed to assess seminal plasma reactive oxygen species (ROS)-antioxidants relationship with varicocele grade in infertile men with oligoasthenoteratozoospermia (OAT). The study included 89 infertile OAT men with varicocele divided into grade I (n = 22) and grade II (n = 43), grade III (n = 24) and compared with 20 healthy fertile controls. In their seminal plasma, two ROS parameters (malondialdehyde [MDA], hydrogen peroxide [H(2) O(2) ]) and four antioxidants (superoxide dismutase [SOD], catalase [Cat], glutathione peroxidase [GPx], vit.C) were estimated. There was significant increase in seminal MDA, H(2) O(2) and significant decrease in seminal SOD, Cat, GPx, vit.C in varicocele-associated OAT cases when compared with the controls. Compared with grade I cases, varicocele cases with grades II, III demonstrated significant increase in estimated seminal MDA, H(2) O(2) and significant decrease in seminal SOD, Cat, GPx, vit.C. It is concluded that seminal oxidative stress (OS) is related to increased varicocele grade in infertile OAT men associated with varicocele.

Abstract
We aimed to assess the effect of spermatic vein ligation on seminal total antioxidant capacity (TAC) in patients with varicocele. Twenty infertile male patients with varicocele and 20 normal fertile men (control group) were included in the study. All the male patients were diagnosed with primary infertility and varicocele. The patients with varicocele were divided into two groups as nonpalpable (GI) (eight patients) and palpable (GII-III) (12 patients) varicocele groups. All the patients underwent microsurgical spermatic vein ligation. Seminal TAC levels and sperm parameters were evaluated in all the patients. Preoperative sperm count, sperm motility, sperm morphology and seminal TAC levels with equivalent figures 3-6 months after spermatic vein ligation and the same values of the control group were compared. There was a statistically significant increase in the total seminal antioxidant capacity level after spermatic vein ligation, and there was a statistically significant increase in the sperm count, sperm motility and spermatozoa with normal morphology. However, evaluation of the patients for varicocele grade showed a statistically significant increase in the TAC level only in the GII-III varicocele group. Spermatic vein ligation can improve the total seminal antioxidant capacity levels especially in patients with middle and high grade varicocele.

Abstract
OBJECTIVES To evaluate whether clinical varicoceles are associated with abnormal semen parameters and whether varicocelectomy could improve the parameters in patients with causes other than infertility. METHODS A total of 268 adult men with clinical varicocele underwent microsurgical varicocelectomy resulting from causes other than infertility. A retrospective analysis of total sperm count, total motile sperm count, sperm concentration, motility, and morphology were performed. RESULTS Of 268 patients, at least 1 abnormal parameter (concentration, motility, or morphology) was found on preoperative semen analysis in 169 (63.1%) patients for whom 121 postoperative analyses were available. Abnormal sperm concentration was observed in 49 (40.5%) patients, motility in 112 (92.6%) patients, and morphology in 82 (67.8%) patients. Total sperm count, total motile sperm count, sperm concentration, and motility showed statistically significant improvement after microsurgical varicocelectomy, however, sperm morphology did not. Subgroup analysis of patients with oligospermia, asthenospermia, or teratospermia showed significant improvement in all semen parameters after varicocelectomy. The highest improvement rate was observed in sperm concentration of patients with oligospermia when a greater than 20% change in preoperative value was defined as improvement or deterioration in semen parameters. Overall, 92 (76.0%) patients showed improvement in at least 1 semen parameter. CONCLUSIONS The majority of varicocele patients with causes other than infertility had abnormal semen parameters, and most semen parameters showed significant improvement after microsurgical varicocelectomy. Therefore, regardless of the chief complaint, semen analysis should be performed in men with clinical varicocele.
