The role of free radicals in normal cellular functions and different pathological conditions has
been a focus of pharmacological studies in the recent past. Reactive oxygen species (ROS) …

Impairment of normal spermatogenesis and sperm function are the most common causes of
male factor infertility. Abnormal sperm function is difficult to evaluate and treat. There is a …

Defective sperm function is the most common cause of infertility, and until recently, it was
difficult to evaluate and treat. Part of this difficulty was due to our incomplete understanding …

Molecular studies of the causes of male infertility revealed a significant contribution of
oxidative stress. When excessive amounts of reactive oxygen species (ROS) are produced …

Infertility is one of the most stressful conditions amongst married couples. Male factor
infertility is implicated in almost half of these cases. Recent advances in the field of …

Oxidative stress is an important factor for development of male infertility because of very high
rate of cell division and mitochondrial oxygen consumption in testicular tissue as well as …

Reactive oxygen species (ROS) are produced under oxidative stress, such as high oxygen
concentration and during the metabolic consumption of oxygen molecules. Male …

In brief This review focuses on the enzymatic antioxidant mechanisms to fight oxidative
stress by spermatozoa, highlighting the differences among mammalian species. We discuss …

Oxidative stress is a state related to increased cellular damage caused by oxygen and
oxygen-derived free radicals known as reactive oxygen species (ROS). It is a serious …

Infertility affects approximately 15% of couples trying to conceive, and a male factor
contributes to roughly half of these cases. Oxidative stress (OS) has been identified as one …
