Contaminating leukocytes in the ejaculate are an important source of reactive oxygen
species (ROS) in human semen. When present in sufficient numbers, they can have a …

Objective—To characterize generation of reactive oxygen species (ROS) by equine
spermatozoa. Sample Population—Multiple semen samples collected from 9 stallions …

Objectives To determine whether reactive oxygen species (ROS) produced by abnormal or
deficient spermatozoa and polymorphonuclear leukocytes (PMN, activated or not) can affect …

Jenny shows a large endometrial reaction after semen influx to the uterus with a large
amount of polymorphonuclear neutrophils (PMN) migrating into the uterine lumen. PMN act …

Peroxidative damage induced by reactive oxygen species (ROS) has been proposed as one
of the major causes of defective sperm function. In previous studies of the production of ROS …

Objective To investigate whether activated poly-morphonuclear neutrophils (PMN) can affect
sperm motility and to assess the capacity of seminal plasma and of scavengers of reactive …

There are anecdotal reports that equine fertility may decline towards the end of the breeding
season. Previous studies have examined differences in sperm quality between the breeding …

The relationship between the presence of white blood cells (WBCs) and the fertilizing
potential of human semen is still an open question. It is well known that the presence of …

The decrease in foaling rates after artificial insemination with cooled semen warrants the
search for new predictors of fertility. The objectives were to investigate levels of naturally …

Reactive oxygen species (ROS) have beneficial or detrimental effects on sperm functions
depending on the nature and the concentration of the ROS involved, as well as the moment …
