Abnormal spermatozoa frequently display typical features of oxidative stress, ie excessive
level of reactive oxygen species (ROS) and depleted antioxidant capacity. Moreover, it has …

The expanding research interest in the last two decades on reactive oxygen species (ROS),
oxidative stress, and male infertility has led to the development of various techniques for …

Background: Sperm DNA damage is an important factor in the etiology of male infertility.
Objective: The aim of the study was to evaluate the association of oxidative stress induced …

Oxidative stress is a common condition suffered by biological systems in aerobic conditions.
Human semen also has its own molecular guard against the free radicals created by normal …

Recently, there is increasing evidence suggesting that oxidative sperm DNA damage is
closely associated with impaired sperm function and male infertility. 8 …

Objective: To investigate whether a high level of oxidative DNA damage in spermatozoa
occurs in infertile male patients and to examine the influence of antioxidant treatments on …

Excess reactive oxygen species (ROS) beyond the scavenging capacity of antioxidants
leads to DNA damage and oxidation of lipoprotein components at the cellular and …

Evidence suggests that disturbing the balance between reactive oxygen species levels and
antioxidant contents in seminal plasma leads to oxidative stress resulting in male infertility …

Oxidative stress (OS) is a significant cause of DNA fragmentation and is associated with
poor embryo development and recurrent miscarriage. The aim of this study was to compare …

OBJECTIVE: To investigate the causal role of oxidative-stress status on human sperm
motility. DESIGN: To demonstrate that sperm with higher oxidative damage have a lower …
