RESUMO

Varicoceles are a common cause of male infertility, affecting up to 35% of men undergoing fertility evaluations. This study aims to investigate the potential influence of altitude and residence time on the occurrence of varicoceles, as well as on sperm quality and sterility in plateau areas. A total of 168 patients with varicocele were enrolled in the study, and the study population was divided into groups based on their direct exposure to different high altitudes due to their living locations. The internal diameter in Quiet breath (Dr), internal diameter in Valsalva maneuver (Dv), reflux peak value, and reflux time are gradually increased accompanied with altitude elevation and residence time extension. The number of cases above 4,500 m also increased with the severity of varicocele, and the altitude of clinical types was higher than that of subclinical types of varicocele. Especially above 4,500 m, the Dv, Dr, reflux peak value, and reflux time all increased with the severity of varicocele. The severity of varicocele was positively correlated with the residence time in plateau area. Patients with residence time of more than 1 year had higher values of Dr, Dv, differentiation time, reflux peak value, and reflux time than those with residence time of less than 1 year. Compared to 3,650 m, patients with varicocele in 4,500 m also have worse semen quality. Both altitude and residence time are strongly positively related to the severity and incidence rate of varicocele in plateau areas.

RESUMO

INTRODUCTION AND OBJECTIVES: Varicocele is the most common treatable cause of male infertility. The study aimed to compare varicocelectomy efficacy in men with primary (PI) and secondary infertility (SI). PATIENTS AND METHODS: Medical records of 100 men suffering from PI and SI and having varicocelectomy at the Republican Specialized Scientific-Practical Medical Center of Urology were retrospectively selected and analyzed. Patients were divided into 2 groups. Group I included 58 men with PI and Group II 42 men with SI. Preoperative clinical characteristics and semen parameters before and after varicocelectomy were analyzed and compared between groups. RESULTS: Analysis revealed that the mean age of patients of group I was significantly lower (p<0.001) and the duration of infertility was accurately shorter (p<0.01) than those of group II. Main semen parameters increased significantly in group I (e.g., sperm concentration increased by 50%, from 62.2 ± 8.7 to 93.5 ± 10.0 M/ml, and total motile sperm count increased by 113%, from 76.7±17.1 to 163.4±27.8 M p<0.05), while in group II only rate of progressive motile sperm increased significantly (by 107%, from 13.5± .6 to 28.0±5.2% p<0.05). We identified a significant difference in varicocelectomy efficacy between group I and group II in change of total motile sperm count (by 113% vs 74% respectively, p<0.01). We also revealed a discrepancy between groups in correlation ratio (r) between initial and post-surgical percent of progressive motile sperm. CONCLUSIONS: Patients with SI were older and had longer infertility period. Varicocelectomy resulted in significant semen parameters improvement in patients with PI. In patients with SI, only a percent of progressively motile sperm improved significantly. It indicates that advanced male age and long infertility duration may have a negative impact on varicocelectomy success.

RESUMO

BACKGROUND: Varicocele is an abnormal expansion of the pampininias venous plexus in the scrotum, resulting in impaired sperm production and reduced sperm quality. The exact pathophysiological mechanism leading to varicocele-related infertility has not been fully elucidated. Although treatable, varicocele may lead to male infertility. OBJECTIVE: To investigate the relationship between semen parameters, serum InhB and INSL-3 levels, and the degree of varicocele in male patients. METHODS: Serum InhB and INSL-3 were detected. To evaluate the relationship between semen parameters and serum InhB and INSL-3 levels. To evaluate the value of semen parameters and serum InhB and INSL-3 levels in distinguishing disease severity in patients with varicocele. RESULTS: Serum INSL-3 in patients with varicocele decreased with the severity of the disease. Serum INSL-3 was positively correlated with total sperm count and frequency of normal sperm morphology. There was a weak correlation between serum InhB and semen volume, concentration, and total sperm. Patients with different disease severity were similar within the groups, with partial overlap or similarity between varicocele Grade I and Grade II, and significant differences between Grade III and Grade I and II. Semen volume, concentration, total sperm, normal sperm morphology, and serum InhB and INSL-3 levels could distinguish the degree of varicocele. CONCLUSION: Semen parameters and the combination of serum InhB and INSL-3 levels in patients with varicocele are closely related to the severity of the disease. Serum INSL-3 is expected to be a potential biomarker for early clinical intervention.

RESUMO

PURPOSE: The management of infertile patients with unilateral subclinical varicocele (SCV) and contralateral clinical varicocele (CV) remains controversial. We aimed to evaluate the effect of untreating SCV on the outcome of contralateral clinical varicocelectomy in infertile patients with oligoasthenozoospermia (OA). MATERIALS AND METHODS: Infertile patients with the diagnosis of OA who underwent left varicocelectomy were retrospectively evaluated. While all patients in the study had left clinical varicocele (LCV), some patients had concomitant right SCV. Patients were divided into two groups according to the presence or absence of a right SCV accompanying LCV as group 1; (LCV n = 104) or group 2; (LCV with right SCV, n = 74). Patients were evaluated with spermiogram parameters, pregnancy rates and serum levels of follicle stimulating hormone, luteinizing hormone, total testosterone at the first year of the follow-up. RESULTS: The mean sperm concentration increased significantly in both groups. However, group 1 showed significantly greater improvement than group 2. The ratio of progressive motile sperm in group 1 was increased significantly whereas no significant change was shown in group 2. Both the spontaneous pregnancy rate and the pregnancy rate with ART were statistically lower in the group of patients with right SCV. No statistically significant difference was detected in serum hormone levels in both groups after varicocelectomy operations. CONCLUSIONS: Untreated right SCV may have adverse impact on the outcomes of left clinical varicocelectomy. In this context, the right testis can be considered in terms of treatment in patients with right SCV accompanying left CV.

RESUMO

Approximately 1% of the general male population has azoospermia, and nonobstructive azoospermia accounts for the majority of cases. The causes vary widely, including chromosomal and genetic abnormalities, varicocele, drug-induced causes, and gonadotropin deficiency; however, the cause is often unknown. In azoospermia caused by hypogonadotropic hypogonadism, gonadotropin replacement therapy can be expected to produce sperm in the ejaculate. In some cases, upfront varicocelectomy for nonobstructive azoospermia with varicocele may result in the appearance of ejaculated spermatozoa; however, the appropriate indication should be selected. Each guideline recommends microdissection testicular sperm extraction for nonobstructive azoospermia in terms of successful sperm retrieval and avoidance of complications. Sperm retrieval rates generally ranged from 20% to 70% but vary depending on the causative disease. Various attempts have been made to predict sperm retrieval and improve sperm retrieval rates; however, the evidence is insufficient. Further evidence accumulation is needed for salvage treatment in cases of failed sperm retrieval. In Japan, there is inadequate provision on the right to know the origin of children born from artificial insemination of donated sperm and the rights of sperm donors, as well as information on unrelated family members, and the development of these systems is challenging. In the future, it is hoped that the pathogenesis of nonobstructive azoospermia with an unknown cause will be elucidated and that technology for omics technologies, human spermatogenesis using pluripotent cells, and organ culture methods will be developed.

RESUMO

BACKGROUND: Varicocele is the most common correctable cause of male infertility. It was the subject of recent Association française d'urologie (AFU) Comité d'andrologie et de médecine sexuelle (CAMS) recommendations. Since then, the literature has provided additional information. This review will comprehensively reassess current indications for the treatment of varicocele, and revisit contemporary issues in the light of current advances. METHODS: Update of the literature search carried out as part of the CAMS recommendations for the period between 2020 and 2023. RESULTS: Microsurgical sub-inguinal varicocelectomy remains the surgical treatment of choice for infertile men with clinical varicocele and abnormal sperm parameters. It offers recurrence rates of less than 4%. It significantly improves both natural and in vitro fertilization live birth and pregnancy rates, as well as sperm count, total and progressive motility, morphology and DNA fragmentation rates. All in all, it modifies the MPA strategy in around one in two cases. Varicocele grade and bilaterality are predictive of improved sperm parameters and pregnancy rate. Treatment of subclinical varicocele is not recommended. Complications are rare, notably hydroceles (0.5%), unilateral testicular atrophy due to arterial damage (1/1000), hematomas, delayed healing and postoperative pain. Retrograde embolization is an alternative to surgery. CONCLUSION: Whenever possible, the urologist should present and discuss treatment options for varicocele with the MPA team and the patient, taking a personalized approach.

RESUMO

OBJECTIVES: Varicocele is the most common correctable cause of male infertility that always has been a debatable subject as regards how it affects fertility and the best way to treat it. Proper assessment of the disease bilaterality is crucial not to miss one side and not to jeopardize treatment outcome. This study aimed to objectively assess varicocele bilaterality in infertile men aiming to improve treatment outcome in this cohort of patients. METHODS: This prospective study was conducted between January 2019 and January 2022 including infertile males with varicoceles. Assessment of missed concomitant contralateral varicocele done pre-operatively by Color Doppler Ultrasound and intraoperatively by intraoperative Doppler device and measurement of maximal vein diameter of contralateral side. RESULTS: A total of 329 cases completed the study. A hundred cases (30.4%) were initially referred as unilateral varicoceles and 229 (69.6%) as bilateral varicoceles. After reassessment of the study population, bilaterality of varicocele was found to be as high as 98.5% (324/329). Repeat CDUS strongly correlated with the intraoperative measured varicocele diameter (r = 0.9, p < 0.001). Moreover, sperm parameters showed significant improvement 3 and 6 months post varicocelectomy. Normal pregnancy after 1 year of surgery occurred in 118 cases (35.9%). CONCLUSIONS: Varicocele bilaterality in infertile men is underreported. Thorough assessment by expert radiologists and andrologists is of paramount importance not to miss significant pathology or hazard treatment outcome.

RESUMO

Varicocele is a major cause of male infertility. However, few studies have discussed the potential associations between the pain caused by varicocele and preoperative and intraoperative factors. The aim of this study was to evaluate factors potentially associated with changes in pain score after microsurgical varicocelectomy. This retrospective study was conducted between August 2020 and August 2022 at China Medical University Hospital in Taichung, Taiwan. Patient characteristics including age, body mass index, semen analysis, testicular volume, and the number of veins ligated were collected. Preoperative and intraoperative factors were analyzed to determine if they were correlated with changes in numeric rating scale (NRS) after microsurgical varicocelectomy. A total of 44 patients with clinical varicocele underwent subinguinal microsurgical varicocelectomy and were analyzed. The overall pain resolution rate was 91%, and the average satisfaction score after surgery was 9.2 according to their subjective feelings. Multivariate analysis revealed that severe varicocele grade (odds ratio [OR] 16.5, 95% confidence interval [CI] 3.01-90.47; P = .018) and the number of veins ligated (OR 6, 95% CI 1.6-22.48; P = .013), were significantly associated with changes in NRS after surgery. In addition, the area under the receiver operating characteristic curve for changes in NRS and the total number of veins ligated was 0.869. Microsurgical varicocelectomy had a high success rate for scrotal pain and satisfaction. Severe varicocele grade and the number of veins ligated in microsurgical varicocelectomy were associated with postoperative pain improvement.

RESUMO

Introduction: Varicocele is a treatable aetiology of male infertility. Magnification with surgical loupe has been associated with improved outcome and reduced morbidity than the conventional technique without magnification. Objective: To compare the outcomes of two techniques of subinguinal varicocelectomy, with a surgical loupe and without. Patients and Methods: This was a prospective randomised hospital-based study. Forty-six patients were randomised to two arms - Group A: loupe-assisted subinguinal varicocelectomy (LASV) and Group B: open subinguinal varicocelectomy without Loupe (OSV). They all had their semen and hormonal parameters compared preoperatively and at 3 and 6 months postoperatively. Post-operative complications were also assessed. P < 0.05 was considered statistically significant. Results: The mean age was 38.28 ± 4.55 years with a range of 27-46 years. The mean age in Group A was 37.35 ± 4.68 and 39.22 ± 4.33 years in Group B. There was an improvement in motility, sperm count and concentration in both the groups at 3 and 6 months (P < 0.05). However, there was no difference in these parameters on comparison of the two groups at 3 and 6 months (P > 0.05). Follicle-stimulating hormone decline was significant in the OSV group at 3 and 6 months, P = 0.010 and 0.021, respectively. There was no difference in other hormonal parameters both at 3 and 6 months (P > 0.05). The pregnancy rate in each arm of study was 4.3%. All complications occurred in Group B. Conclusion: Both techniques resulted in improvement in seminal fluid parameters. All complications occurred in the arm that had subinguinal varicocelectomy without loupe. Loupe-assisted subinguinal varicocelectomy is safe and effective.

RESUMO

Taohong Siwu Decoction (THSWD) was widely used for the treatment of varicocele-associated male infertility. However, the pharmacological mechanism of action is not completely clear. Therefore, network pharmacology and molecular docking were performed to explore potential mechanism of THSWD in the treatment of varicocele-associated male infertility. The Traditional Chinese Medicine Systems Pharmacology (TCMSP), Swiss Target Prediction, and GeneCards were used to retrieve candidate compounds, action targets, and disease-related targets. The construction of the protein-protein interaction (PPI) network and the screening of core genes were completed by the STRING and Cytoscape 3.9.1, respectively. The DAVID was used to obtain results of gene ontology function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The Mcule analysis platform was used to perform molecular docking. There were a total of 53 candidate compounds and 782 relevant targets in THSWD. There were 45 common targets between THSWD, varicocele, and male infertility, and 23 core genes were found in the PPI network. Biological processes involved response to hypoxia, regulation of blood pressure, cellular response to hypoxia, and regulation of the nitric oxide biosynthetic process. Furthermore, the KEGG pathway enrichment analysis showed that the common targets mainly regulated the disease of varicocele-associated male infertility through the HIF-1 signaling pathway, PI3K-Akt signaling pathway, Relaxin signaling pathway, and TNF signaling pathway. Finally, the molecular docking showed that luteolin, quercetin, and kaempferol had good intercalation with major targets. As predicted by network pharmacology, THSWD regulated varicocele-associated male infertility through multiple compounds and targets, and its mechanism was closely related to inflammatory response, reactive oxygen species damage, and function of blood vessels.

RESUMO

INTRODUCTION: The subinguinal microsurgical varicocelectomy is considered as the gold standard surgical technique for the treatment of varicocele. The objective of this study is to evaluate the results of this technique on the resolution of pain and the parameters of sperm analysis. METHODS: Single-center, retrospective study that includes 22 patients who have been operated over a period of six months for a clinically palpable varicocele via the microsurgical subinguinal technique. Nine patients were operated for pain and 13 patients for infertility with an abnormality of their sperm analysis. RESULTS: All the patients operated for pain had a complete resolution of pain at the postoperative follow-up (3 months). Concerning the patients operated for infertility, 76.92% of the patients had a normal sperm analysis, 7.69% of the patients presented a partial improvement, and 15.39% of the patients without any improvement. Analysis of sperm's parameters at 3 months showed a significant improvement in the morphology (4.3% vs 6.69% of typical forms according to Kruger ; P<0.05) and mobility (progressive mobility 15.6% vs 23% postoperatively; P<0.01). A non-significant improvement (low sample) in the concentration was noted (21.58 million/mL preoperative vs 34.9 million/mL postoperative, P=0.08). Pregnancies are noted in 38.5% of patients. A postoperative complication was noted with surgical site infection resolved with antibiotics. CONCLUSION: This single-center study confirms that the treatment of varicocele by subinguinal microsurgical route is an effective therapeutic strategy on symptomatic varicocele and in infertile men. This technique is associated with few complications.

RESUMO

BACKGROUND: Mechanisms to explain inflammation in male infertility of unknown cause are still being investigated. The inflammasome is a key regulator of innate immunity in the inflammatory response to infections. Our study aims to investigate the effects of varicocele on infertility, its relationship with antioxidant and inflammasome mechanisms, and how it could be guided in azoospermic or nonazoospermic patients. METHODS: A cross-sectional cohort study was conducted at the department of urology in our university hospital. Eightyeight randomly selected men aged 20-45 admitted to our hospital because of infertility between September 2019 and July 2020 were included in the study. Patients were divided into four equal groups according to their clinical status, those with/without azoospermia and with/without varicocele. Blood and semen samples were taken from the patients. NOD-like receptor pyrin domain-containing 3 (NLRP3) and interleukin-1 beta (IL1ß) and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) levels were measured in serum and semen, and the groups were compared statistically. RESULTS: Serum and semen NLRP3, IL1ß, TAS, TOS, and OSI values of the patients with varicocele or azoospermia were significantlyhigher than those without either varicocele or azoospermia (p < 0.05). The oxidative stress markers TAS, TOS, and OSI values were significantly higher in the other groups than those without azoospermia and varicocele (p < 0.05). DISCUSSION: Inflammasome mechanisms, such as NLRP3 and IL1-ß molecules, may provide additional benefit in evaluating the need and benefit of surgical or medical treatment in infertility with and without vascular pathology and with and without azoospermia.

RESUMO

BACKGROUND: Scrotal swelling from varicocele is a common complaint in adult men. Varicocele due to portosystemic collaterals is a rare presentation of portal hypertension. Imaging workup and intervention for varicocele in this case is more complex than varicocele due to absent or incompetent valves in the testicular veins and pampiniform plexus. CASE PRESENTATION: We present the case of a 53-year-old man with alcohol-related cirrhosis presented with persistent left scrotal heaviness, pain, and swelling found to have a large left varicocele. Given his history of cirrhosis, a contrast-enhanced CT of the abdomen and pelvis was obtained showing that the varices were supplied by a vessel arising from the splenic vein and draining into the left renal vein as well as gastric varices. Varicocele embolization alone is not sufficient in this case, and we treated with transjugular intrahepatic portosystemic shunt, variceal and varicocele embolization. CONCLUSION: In patients presenting with a varicocele with a history of cirrhosis/portal hypertension, cross sectional imaging of the abdomen and pelvis should be obtained prior to treatment to evaluate for the presence of varices which may be pressured by varicocele embolization. If present, consideration should be given to referral to an interventional radiologist for possible concurrent variceal embolization and TIPS placement.

RESUMO

Pelvic congestion syndrome (PCS) in females and varicoceles in males may be regarded as closely related conditions since the main pathophysiological cause for both processes is pelvic venous insufficiency. Varicoceles are more prevalent amongst sub-fertile males, with an approximate incidence of 15% in the general male population. PCS is commonly diagnosed amongst premenopausal multiparous women, representing one of the leading causes of chronic pelvic pain. Both conditions appear to be predominantly left-sided and are associated with oxidative stress and pro-inflammatory cascades with subsequent effects on fertility. Clinical examination and pelvic ultrasonography play an essential role in the assessment of varicoceles, PCS and chronic pelvic pain. Venography is generally considered as a gold-standard procedure for both conditions. There is still much debate on how these conditions should be managed. This review article provides a comparative analysis of the underlying pathophysiological mechanisms of both PCS and varicoceles, their impact on fertility, as well as their clinical management.

RESUMO

The present study compared seminal calbindin 2 (CALB 2) levels and semen parameters in men with and without varicocele. CALB 2 is also known as calretinin and 29 kDa calbindin. The study was a case-control study conducted from April (2021) to March (2022) in the andrology department at Beni-Suef University hospital. The study included four matched groups: group (I) were controls (fertile normozoospermic men without varicocele) (n=24). Group (II) were fertile normozoospermic men with varicocele (n=24). Group (III) were infertile oligoasthenoteratozoospermia (OAT) men without varicocele (n=24). Group (IV) were infertile OAT men with varicocele (n=24). The lowest levels of seminal CALB 2 were found in patients with severe oligozoospermia which showed a statistically significant difference when compared to seminal CALB 2 in patients with normal, mildly low, or moderately low sperm counts. There were significant negative correlations between sperm concentration, sperm motility and percentage of normal sperm forms and seminal CALB 2. Seminal plasma CALB 2 may play a role in the negative impact of varicocele on the semen parameters especially sperm concentration, sperm motility and percentage of sperm normal forms. Future studies are needed to verify these findings.

RESUMO

METHODS: We performed a non-randomized comparative trial that recruited infertile men with varicocele who were scheduled to undergo MSV. Eligible patients were allocated by the investigators in a 1:1 ratio to receive intraoperative Doppler (group I) or intraoperative Doppler plus hydrodissection (group II). RESULTS: Sixty men were included in each group. The two study groups showed a comparable number of ligated veins on the right (4.22 ±1.57 versus 4.42 ± 1.65; p = 0.49) and left side (6.77 ± 2.14 versus 6.98 ± 2.29; p = 0.59). On the contrary, group II showed a significantly higher number of preserved arteries on the right (2.42 ± 0.56 versus 1.47 ±0.5 in group I) and left side (2.6 ± 0.53 versus 1.63 ± 0.55 in group I), with p-value < 0.001. The sperm motility was significantly higher in group II than in group I (21.25 ± 13.73 versus 13.85 ± 12.25, respectively; p = 0.002). In both groups, the sperm motility increased significantly at the end of follow-up compared to the preoperative period. The postoperative sperm mortality remained significantly higher in group II than in group I (p = 0.008). CONCLUSIONS: Intraoperative Doppler plus hydrodissection (D+IH-MSV) has advantages in preserving more arteries and enhancing the motility of sperms. Based on these findings, we strongly recommend D+IH-MSV when treating infertile men with varicocele.

RESUMO

INTRODUCTION: Inguinal hernia and varicocele are common conditions in male population. Laparoscopy brings the opportunity to treat them simultaneously, through the same incision. However, there are different opinions about the risks for testicular perfusion of multiple procedures in the inguinal region. In this study, we assessed the feasibility of simultaneous laparoscopic procedures by studying clinical and surgical outcomes of patients undergoing bilateral inguinal hernioplasty using the transabdominal preperitoneal (TAPP) technique with and without concomitant bilateral laparoscopic varicocelectomy (VLB). METHODS: a sample of 20 patients from the University Hospital of USP-SP with indirect inguinal hernia and varicocele with indication for surgical correction was selected. Patients were randomized into two groups, 10 undergoing TAPP (Group I) and 10 undergoing simultaneous TAPP and VLB (Group II). Data regarding total operative time, complications and postoperative pain was gathered and analyzed. RESULTS: there was no statistical difference between groups regarding total operative time and postoperative pain. Only one complication (spermatic cord hematoma) was observed in Group I and no complications were observed in Group II. CONCLUSIONS: simultaneous TAPP and VLB in was shown to be effective and safe, which provides a basis for conducting studies on larger scales.

RESUMO

Background: This study evaluated whether microsurgical varico-celectomy performed in infertile men with severe oligozoospermia (SO) resulted in improved semen parameters or increased rates of spontaneous pregnancy (SP) and performed a cost-effectiveness analysis comparing intrauterine insemination (IUI), in vitro fertilization (IVF), and varicocelectomy. Methods: This study included 25 patients with SO who underwent microsurgical varicocelectomy between September 2019 and May 2022, which resulted in post-surgical SP in all cases. Men with azoospermia, abnormal karyotype, or Y-chromosome microdeletion were excluded from the study. Serum luteinizing, follicle-stimulating, and testosterone hormones were measured preoperatively. Semen was analyzed every 3 months postoperation. The incidence of SP was recorded at each visit. Cost-effectiveness for assisted reproductive technologies was calculated based on reported costs. Several parameters were evaluated as potential predictors of the response to microsurgical varicocelectomy using univariate and multivariate analyses. Results: After a mean postoperative observation period of 7 months, 25 couples with SP after microsurgical varicocelectomy were recruited. The mean sperm concentration increased from 3 million/mL (interquartile range [IQR]: 2-5 million/mL) to 12 million/mL (IQR: 5-17 million/mL; p<0.05), and mean sperm motility improved from 4% (IQR: 3%-6%) to 7.6% (p<0.05). Total motile sperm count (TMSC) increased to 3.08 million (IQR: 1.02-5.83 million) from a preoperative value of 0.34 million (IQR: 0.16-0.83 million). A cost-effectiveness analysis comparing IVF with varicocelectomy indicates that varicocelectomy may represent a better first-line option for infertile men with very low preoperative TMSC. However, further research remains necessary to confirm this result. Conclusion: Varicocelectomy should be discussed as a treatment option for men with SO and may improve sperm quality and fertility potential, resulting in SP.

RESUMO

Varicocele is abnormal tortuosity and dilatation of the pampiniform plexus veins within the spermatic cord. Varicocele is associated with testicular atrophy, hypogonadism, impaired semen analysis values, or decreased testosterone production. Varicocele is a progressive disease and should be treated because it may be a systemic disease that can be associated with cardiovascular abnormalities. We hypothesize in this study that cardiovascular and hemodynamic pathologies may occur in varicocele patients. In this prospective, multicentric, multidisciplinary study, patients diagnosed with high-grade left varicocele in the urology clinic underwent semen analysis, total testosterone determination, and scrotal Doppler ultrasonography. In addition, blood pressure measurement and echocardiographic evaluation were performed by blinded cardiologists in both the varicocele patients and the healthy control group. The study was carried out with 103 varicocele patients and 133 healthy individuals who formed the control group. Diastolic blood pressure (P = 0.016), left ventricular end diastolic (P < 0.001) and systolic diameter (P < 0.001), ejection fraction (P < 0.001), pulmonary arterial pressure (P < 0.001), and aortic distensibility (P < 0.001) values were significantly higher in varicocele patients compared with controls; interventricular septum wall thickness (P = 0.022), aortic systolic (P < 0.001) and diastolic diameter (P < 0.001), aortic systolic (P < 0.001) and diastolic diameter index (P < 0.001), and aortic stiffness index (P < 0.001) values were significantly lower in varicocele patients. The mean aortic distensibility of non-normozoospermic group was lower than that of normozoospermic group (P = 0.041). There was no statistically significant relationship between thickest vein diameter in spermatic cord and cardiological parameters. This study showed that symptomatic patients with high-grade varicocele had a higher risk of cardiovascular and hemodynamic disease. We recommend that men with high-grade symptomatic varicocele with impaired semen analysis undergo cardiovascular and hemodynamic evaluation regardless of their spermatic vein diameter.
