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...

AIM Despite many studies published in recent years concerning the relationship between demographic factors and varicocele, this issue remains controversial. The aim of this study was to identify a possible influence of body mass index (BMI) and height on occurrence varicocele in men. METHODS In a case-control study 153 patients aged 18-40 years from 2004 to 20014, with moderate and sever vari...

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 RECENT FINDINGS Since the advent of technologies bypassing boundaries of natural selection, this question may seem outdated.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...

Varicocele is characterized by an abnormal dilatation and retrograde blood flow in the spermatic veins. Varicocele is the leading correctable cause of male infertility. Although it is highly prevalent in infertile men, it is also observed in individuals with normal fertility. Determining which men are negatively affected by varicocele would enable clinicians to better select those men who will ...

Varicocele is one of the most common causes of primary male infertility. Pilea microphylla (PM) is being used as folk medicine. This study was aimed to investigate the effects of PM in a rat model of varicocele. A total of 30 male Wistar rats were divided into control, sham, varicocele, accessory varicocele and PM-treated groups. After 10 weeks of varicocele induction, sperm parameters and chro...

OBJECTIVES Varicocele, a dilatation of the pampiniform venous plexus, is considered to cause male infertility. The exact mechanism of varicocele development is not clarified yet. This study focused on the structure of varicocele veins, compared with normal spermatic veins, and its potential role in varicocele development. METHODS Morphologic and immunohistochemical studies using antibodies ag...

The possible interrelation between male reproductive disorders and iris pigmentation is poorly understood. We have found a link between eye colour and the existence of adolescent varicocele. Therefore, we aimed to extend our investigation on the relationship between the eye colour and varicocele in adult men. 231 andrology outpatients from Caucasian origin were included in the study. The presen...

PURPOSE Because varicocele is seen often in infertile men and oxidative stress has been implicated in sperm dysfunction, we assessed spermatozoal reactive oxygen species and seminal total antioxidant capacity in men with and without varicocele. MATERIALS AND METHODS Levels of reactive oxygen species and total antioxidant capacity were measured in the semen of 21 infertile men with varicocele,...

OBJECTIVES Varicocele is associated with impaired testicular function and male infertility, but the molecular mechanisms by which fertility is affected have not been satisfactorily explained. The aim of our study was to investigate whether or not the polymerase gamma (POLG) polymorphism is associated with Iranian varicocele patients. MATERIALS AND METHODS We determined the POLG CAG repeat len...

OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...
