objective(s): increased levels of nitric oxide (no) in the testicular veins of people suffering from varicocele have already been reported. however, the role of no-synthase (nos) isozymes and their inhibitors have not been extensively studied. we aimed to evaluate the inhibitory effects of aminoguanidine (ag), on sperm motility, vitality, and mitochondrial membrane potential (mmp) in varicoceli...

in this study we have described our varicocele cases in terms of associated symptoms/signs. in addition, we have tested the correlation between semen parameters and varicocele grades and compared the relative frequencies of associated symptoms/signs in different varicocele grades. 1 19 referred cases of varicocele were categorized based on clinical criteria into 3 grades by one examiner. the re...

Ann Saudi Med 2006;26(3):228-230 Intratesticular varicocele is a rare condition, with a reported incidence of less than 2%.1 Its clinical significance is not well established. The condition is characterized by dilatation of the intratesticular veins in and around the mediastinum testis. color Doppler ultrasound can confirm the diagnosis. We present a case of a young man with nephrotic syndrome ...

A 22-year-old man was admitted to our hospital with left testic...

There are several options for the treatment of varicocele, including surgical repair either by open or microsurgical approach, laparoscopy, or through percutaneous embolization of the internal spermatic vein. The ultimate goal of varicocele treatment relies on the occlusion of the dilated veins that drain the testis. Percutaneous embolization offers a rapid recovery and can be successfully acco...

conclusions our findings indicated that oxidative stress could play an essential role in male infertility caused by varicocele and may impair spermatogenesis leading to infertility. objectives in the current study, we aimed to assess the tac (total antioxidant capacity) and mda (malondialdehyde) as stress oxidative markers in infertile men with varicocele and fertile men, and moreover, their co...
