Varicoceles are present in 15% of the normal male population and in approximately 40% of men presenting with infertility. The preponderance of experimental data from clinical and animal models demonstrates a deleterious effect of varicoceles on spermatogenesis. Testicular temperature elevation and oxidative stress appear to play an important role in varicocele-induced testicular dysfunction, al...

Purpose: To evaluate the current literature on the varicocele treatment and impact on fertility. Materials and Methods: Pertinent articles were identified through PubMed search on varicocele repair and male infertility. Discussion: The proposed mechanisms of how varicocele results in impaired spermatogenesis and infertility include an altered or impaired testicular blood flow, increased scrotal...

AIM Varicocele is characterized by abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord and is one of the causes related to male infertility. This study aimed to investigate the correlation between varicocele and somatometric parameters. We also aimed to determine prevalence and treatment ratio of this disorder among healthy young Turkish men. MA...

Background: Varicocele is associated with impaired spermatogenesis. It may also be associated with the patients' weight. We aimed to determine the relationship between body mass index (BMI) and the frequency and grade of varicocele among a sample of Iranian men in southeast Iran. Methods: This cross-sectional study was conducted during 2010 and 2011 among 167 men who referred to the University ...

Background: Varicocele is the most common cause of male infertility. About 20–30% men with varicocele are infertile. The clinically obvious varicocele is identifiable and correctable cause of male infertility, but less is known about the subclinical varicocele and its relationship to infertility. However, subclinical varicocele seems to be an important cause of infertility and hence scrotal ult...

INTRODUCTION Elevated nitric oxide (NO) levels have been shown to have toxic effects on sperm function and motility. This study was conducted to compare NO levels in the seminal fluid of infertile men with varicocele with those of infertile and fertile men without varicocele. MATERIALS AND METHODS Semen samples were obtained from 40 infertile men with varicocele (group 1), 40 infertile men wi...

Introduction: A varicocele is the abnormal dilation and tortuosity of venous plexus above the testicles. The pattern of abnormal heat distribution in the scrotum can be detected through thermal imaging, which is a distant, non-contact, and non-invasive method. The aim of the present study is to detect and grade varicocele. Materials and Methods: This study was conducted on 50 patients with high...

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 i...

Background: The nutcracker syndrome represents a clinical condition caused by compression of the left renal vein (LRV) between the superior mesenteric artery (SMA) and the aorta. One of its manifestations is left-sided varicocele. The aim of this study is to determine the prevalence of nutcracker syndrome in patients with primary and recurrent high grade left-sided varicocele. Methods: Fifty pa...
