Varicocele, the leading cause of male infertility, can impair sperm quality and fertility via various oxidative stress mechanisms. An imbalance between excessive reactive oxygen species production and antioxidant protection causes alterations in nuclear and mitochondrial sperm DNA, thus rendering a subset of varicocele men less fertile. In particular, sperm DNA fragmentation is usually elevated in men with clinical varicocele in both abnormal and normal semen parameters by the current World Health Organization criteria...

PURPOSE: Varicocele may disrupt testicular microcirculation and induce hypoxia-ischemia related degenerative changes in testicular cells and spermatozoa. Superoxide production at low oxygen concentrations exacerbates oxidative stress in men with varicocele. Therefore, the present study was designed to study the role of mitochondrial redox regulation and its possible involvement in sperm dysfunction in varicocele-associated infertility. MATERIALS AND METHODS: Differentially expressed mitochondrial proteins were identified in 50 infertile men with varicocele and ten fertile controls by secondary LC-MS/MS data-driven in silico analysis...

Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis (n = 253), Grade III varicocele (n = 106), and both conditions (n = 125) were compared with a control group (n = 168) composed of men without these disorders or any other recognized causes of male infertility...

BACKGROUND: Varicocele is a common urologic anomaly in adolescent males; however, evidence-based treatment guidelines do not exist. Hydroceles are known to be a common complication after surgical therapy, with a wide variation in the reported incidence between 1 and 40%. AIM: This study aimed to introduce a standardized indication-to-treat protocol and prove its efficacy by analyzing the outcome of patients. Secondly, it aimed to better define postoperative hydroceles because the wide variation of reported incidence is attributed to a lack of definition...

BACKGROUND: Polidocanol is approved for its competence in treatment of varicose veins and spider veins; however, unfortunately, many of its off-label uses are still underappreciated. OBJECTIVE: Lack of an appropriate comprehensive review for off-label uses of this medication troubles physicians about making evidence-based decisions on prescribing it for its various outstanding off-label uses. This article attempts to provide physicians with the latest information concerning successful and unsuccessful use of polidocanol as an alternative treatment for esophageal and gastric varices, tendinopathy and epicondylitis, vascular malformations, varicocele, hydrocele and spermatocele, aneurysmal bone cysts, itching, management of gastrointestinal bleeding, simple renal cysts, reducing the incidence and severity of radio-induced dermatitis, and hemorrhoids...

Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele...

Introduction The Tauber procedure, i.e., antegrade sclerotherapy for varicocele, can lead to ischemic colitis. The pathogenesis can involve an atypical systemic-portal communication, which could represent an infrequently reported (rare) anatomical variant. The aim of this study is to review clinical cases from the literature to highlight the anatomical bases of such complications. Materials and methods A computer-aided and hand-checked review of the literature was used to identify relevant publications. Also, the computed tomography (CT) examination of a clinical case with medico-legal implications due to severe vascular complication following Tauber's procedure was reviewed...

Objectives: Varicocele is an abnormal dilation in the testicular vein, which can cause hypoxia, reactive oxygen species accumulation, elevation in testicular temperature, and promote apoptosis and increase proinflammatory cytokine production. According to the varicocele pathophysiology, it is possible that a group of cytosolic receptors called nucleotide oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes also involve in varicocele pathogenesis...

Venous aneurysms are rare entities, with mesenteric venous aneurysms among the rarest reported. We present a case of a 66-year-old man with abdominal pain secondary to an enormous 7.8-cm inferior mesenteric vein aneurysm. In addition, he had evidence of other venous abnormalities, including bilateral leg chronic venous insufficiency and a right varicocele. This appears to be the only reported case of an isolated inferior mesenteric vein aneurysm. Adding to its significance, this aneurysm is among the largest of any mesenteric vein aneurysm reported...

Varicocele-related sperm damages are usually caused by oxidative stresses. Growing evidence indicates that lncRNA growth arrested DNA-damage inducible gene 7 (gadd7) is involved in the regulation of the oxidative stress responses. In this study, we measured the expression level of gadd7 in the sperm and found that the expression of gadd7 was significantly up-regulated in patients with varicocele compared with the healthy control. The relative expression level of gadd7 was negatively correlated with the sperm count...
