Infertility is a global health problem involving about 15% of couples. Approximately half of
the infertility cases are related to male factors. The oxidative stress, which refers to an …

Oxidative stress (OS) is a result of the imbalance between reactive oxygen species (ROS)
and antioxidants in the body that can cause tissue damage. Oxidative stress has a …

The nonhormonal medical treatment can be divided into empirical, when the cause has not
been identified, and nonempirical, if the pathogenic mechanism causing male infertility can …

Oxidative stress and reactive oxygen species (ROS) are generated from both endogenous
and environmental resources, which in turn may cause defective spermatogenesis and male …

Purpose Although oxidative stress is thought to be an important cause of male infertility,
primarily due to DNA and cell membrane damage, little is known about the genetic causes …

Background Oxidative stress is caused by the imbalance occurring between the creation
and clearance of the reactive oxygen species (ROS), which is responsible for 30–40% of …

Inconsistent results of association studies investigated the role of glutathione S–transferase
genes in idiopathic male infertility may be explained by ethnical differences in gene–gene …

In a number of malignancies, oxidative stress plays a role. SOD is an endogenous
antioxidant enzyme that aids in the reduction of oxidative stress. The goal of this study was …

Enzymatic factors including superoxide dismutase (SOD), glutathione peroxidase (GPX),
and catalase (CAT) are among the most important protective antioxidant systems in human …

Catalase (CAT) plays a central role in the protection of different cell types against the
