AIM The aim of this study was to evaluate the hemodynamics of varicocele using Doppler ultrasonography and scrotal scintigraphy, and to compare the value of these two methods in the prediction of seminal improvement after varicocelectomy. MATERIALS AND METHODS A total of 40 men with left sided varicocele presented for surgery because of infertility of at least one year in duration. Preoperati...

OBJECTIVE The incidence of varicocele is approximately 15% in adolecent men. Early treatment with varicocele is aimed to resolve testicular hypotrophy and ensure catch-up growth. The aim of this study was to evaluate ipsilateral catch-up growth rates relative to contralateral testicular growth in adolescents with varicocele undergoing microsurgical subinguinal varicocelectomy. MATERIAL AND ME...

Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-...

BACKGROUND Varicocele is associated with high levels of DNA damage in spermatozoa due to oxidative stress and elevated levels of sperm DNA fragmentation, which has been currently proposed to be an essential additional diagnostic test to be recommended for patients with clinical varicocele. The aim of this study was to evaluate the parameters of semen and the DNA fragmentation index (DFI) in pat...

BACKGROUND The most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress. OBJECTIVE Our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on sperm parameters and f...

PURPOSE Microsurgical varicocelectomy procedures are known to have high rates of success and minimal incidence of postoperative hydrocele occurrences in adults. Herein, we report our initial experience with microsurgical inguinal and subinguinal techniques for the treatment of varicoceles in adolescent patients. PATIENTS AND METHODS A total of 9 boys (averaged age 12.7 years each younger than...

BACKGROUND Since nitric oxide (NO) has an oxidant activity, lower levels following a varicocelectomy may result in better functioning sperm, improved semen quality and consequently higher fertility rates. However, this procedure should be examined in more detail. OBJECTIVES Accordingly, this study was performed to compare the before and after varicocelectomy levels of NO in the seminal fluid ...

There is evidence to show that varicocele repair can improve conventional sperm parameters but the effects on sperm chromatin integrity have not been fully elucidated. We sought to examine the effects of varicocelectomy on sperm maturation, nuclear chromatin integrity and nuclear sulfhydryl groups. We conducted a prospective study of consecutive infertile men (n=29) that underwent a microsurgic...

Varicocele is one of the most common causes of male infertility and spontaneous pregnancy rate after varicocelectomy is only about 30%. The most important seminal antioxidant is vitamin C but recent studies about the effects of vitamin C on spermatogenesis are controversial; therefore, we decided to evaluate its role after varicocelectomy. In a double blind randomized controlled clinical trial,...

Varicoceles are a major cause of impaired spermatogenesis and the most common correctable cause of male infertility. They are found in approximately 40% of men with primary infertility and 80% of men with secondary infertility, although they also occur in 12% of men with normal semen parameters. The presence of a varicocele does not always affect spermatogenesis, as it has been reported that on...
