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

After being historically considered as noxious agents, nitric oxide (NO) and hydrogen sulfide
(H2S) are now listed as gasotransmitters, gaseous molecules that play a key role in a variety …

Chemotherapy is associated with male infertility. Cisplatin (cis-diamminedichloro-platinum
(II)(CDDP) as a chemotherapy medication used to treat a number of cancers has been …

Varicocele is a major cause of infertility and may impair spermatogenesis. This study
evaluated the molecular consequences of varicocele on the induction of heat‐shock …

Aminoguanidine is a selective inhibitor of the inducible nitric oxide synthase (iNOS) and a
scavenger of reactive oxygen species (ROS). Numerous studies have shown the antioxidant …

To investigate the effect of supplementation of L-arginine (AR) on sub-fertile buffalo-bulls'
ejaculates, 25 ejaculates of poor motility (40 to 55%) were collected by artificial vagina from …

Background and purpose: The sperm of infertile men with varicocele exhibit markedly high
DNA damage that appears to be related to high oxidative stress (OS). Aminoguanidine (AG) …

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 …

One of the proposed mechanism by which varicocele induces its damage is excessive
release of nitric oxide (NO). Several studies have shown the role of NO in poor sperm quality …

Nitric oxide (NO) is a major gasotransmitter involved in several physiological processes of
male reproduction. There is, nevertheless, little information concerning the role of NO during …
