Sperm is particularly susceptible to reactive oxygen species (ROS) during critical phases of
spermiogenesis. However, the level of seminal ROS is restricted by seminal antioxidants …

Varicocele is recognized as the leading cause of male infertility because it can impair
spermatogenesis through several distinct pathophysiological mechanisms. Current …

Varicocele is the most common and treatable cause of male infertility. Studies of a rat
experimental left varicocele model and human testicular biopsy samples have shown the …

Reactive nitrogen species (RNS) is a subset of free oxygen radicals called reactive oxygen
species (ROS). Physiological levels of ROS are necessary to maintain the reproductive …

Varicocele, the leading cause of male infertility, can impair spermatogenesis through several
pathophysiological mechanisms. Of these, current evidence suggests that oxidative stress is …

Reactive nitrogen species (RNS), like reactive oxygen species (ROS), are useful for
sustaining reproductive processes such as cell signaling, the regulation of hormonal …

BACKGROUND: Varicoceles are associated with venous flux that may cause increased heat
and interstitial pressure within the testes, but these effects are variable. Some men with …

The aim of this study was to explore the effects of varicocele on the morphology and function
of Leydig cells in the rat testis. Forty male Sprague–Dawley rats were divided into two …

OBJECTIVES. Varicocele results from the abnormal dilation of the veins of the pampiniform
plexus and is the most common identifiable cause of male infertility. It can develop during …

OBJECTIVES: The pathophysiology of the testicular damage in varicocele have not been
completely understood. There are several studies concerning the effects of increased …
