Background: One of the causes of male fertility disorders is the exposure of oxidative stress
on the human sperm. Understanding the mechanism of disturbance is important to develop …

OBJECTIVE: To investigate sperm viability, incidence of apoptosis, and intracellular basal
and induced reactive oxygen species (ROS) in sperm fractions. DESIGN: Prospective …

Objective: To evaluate the effects of oxidative stress on DNA and plasma membrane integrity
of human spermatozoa. Design: Prospective cohort study. Setting: University-based, tertiary …

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 …

Our study aimed to assess the impact of sperm oxidative stress on embryo development by
means of a dose-dependent model. In experiment 1, straws from five bulls were subjected to …

The aim of this study was to explore the effect of zinc on hydrogen peroxide-induced sperm
damage in assisted reproduction techniques. First, sperms were selected from semen …

Infertility is among the most serious medical problems worldwide. Male factors contribute to
40%–50% of all infertility cases, and approximately 7% of men worldwide are affected by …

The production of reactive oxygen species (ROS) is a normal physiological event in the male
germ line. ROS are a double-edged sword, despite its role as key signaling molecules in …

Human sperm susceptibility to oxidative stress is vital as it affects various characteristics of
sperm function. In the present study, we report a simple, sensitive and quick method of …

The reactive oxygen species (ROS) that is most damaging to human spermatozoa is
hydrogen peroxide. Using an artificial medium Ham's F-10, we have evaluated the effect of …
