In semen, granulocytes are major producers of reactive oxygen species (ROS), which can
damage sperm. The diagnosis of leukocytospermia is usually based on the World Health …

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 …

The purpose of this study was to determine whether normospermic infertile men have high
seminal oxidative stress, using 3 measures of oxidative stress: reactive oxygen species …

Purpose Although the significance of leukocytospermia in semen remains controversial,
evidence exists that white blood cells (WBCs) may adversely affect sperm function and act …

Background Leukocytes contribute directly and indirectly to reactive oxygen species (ROS)
production. Although leukocytospermia is defined as the presence of≥ 1× 10 6 white blood …

Although reactive oxygen species (ROSs) are clearly implicated in the pathogenesis of male
infertility, few studies have attempted to define the basal levels of ROSs in fertile men. Levels …

Objective: To determine whether particular semen characteristics in various clinical
diagnoses of infertility are associated with high oxidative stress and whether any group of …

Spermatozoa are constantly exposed to the interphase between oxidation through high
amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of …

Purpose A physiological balance exists between seminal reactive oxygen species (ROS)
and antioxidant capacity. An overproduction of ROS which exceeds the seminal plasma …

OBJECTIVE: To investigate the role of increased seminal leukocytes in enhancing reactive
oxygen species (ROS) production by human spermatozoa. DESIGN: A prospective study …
