Reactive oxygen species (ROS) play a critical role in defining the functional competence of
human spermatozoa. When generated in moderate amounts, ROS promote sperm …

Oxidative stress plays a major role in the life and death of mammalian spermatozoa. These
gametes are professional generators of reactive oxygen species (ROS), which appear to …

Male and female germ lines are vulnerable to oxidative stress. In spermatozoa, such stress
triggers a lipid peroxidation cascade that culminates in the generation of electrophilic lipid …

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 …

A state of oxidative stress (OS) and the presence of reactive oxygen species (ROS) in the
male reproductive tract are strongly correlated with infertility. While physiological levels of …

During recent years, an increasing percentage of male infertility has to be attributed to an
array of environmental, health and lifestyle factors. Male infertility is likely to be affected by …

To date 15% of couples are suffering from infertility with 45–50% of males being
responsible. With an increase in paternal age as well as various environmental and lifestyle …

This article addresses the importance of oxidative processes in both the generation of
functional gametes and the aetiology of defective sperm function. Functionally, sperm …

Spermatozoa are highly vulnerable to oxidative attack because they lack significant
antioxidant protection due to the limited volume and restricted distribution of cytoplasmic …

Background Angiotensin-converting enzyme II (ACE2), a receptor for Severe Acute
