Sperm DNA integrity is crucial for fertilization and development of healthy offspring. The
spermatozoon undergoes extensive molecular remodeling of its nucleus during later phases …

Sperm cryopreservation represents a powerful tool for livestock breeding. Several efforts
have been made to improve the efficiency of sperm cryopreservation in different ruminant …

In up to 50% of cases, infertility issues stem solely from the male. According to some data,
the quality of human semen has deteriorated by 50%–60% over the last 40 years. A high-fat …

Infertility is defined as a couple's inability to conceive after at least one year of regular
unprotected intercourse. This condition has become a global health problem affecting …

The effects of reactive oxygen species on male fertility are governed by the oxidative
paradox, defined by a delicate balance between oxidative stress and antioxidant capacity …

Cooled preservation of semen is usually associated with artificial insemination and genetic
improvement programs in livestock species. Several studies have reported an increase in …

Oxidative stress generates a large amount of reactive oxygen species (ROS) and affects
sperm quality via damaging sperm DNA and compromising the intracellular homeostasis in …

It is widely accepted that oxidative stress plays an important role in the pathophysiology of
male infertility and that antioxidants could have a significant role in the treatment of male …

The evolutionary theory of aging supports a trade-off relationship between reproduction and
aging. Aging of the male reproductive system primarily affects the testes, leading to a …

Graphical abstract Abstract Infertility affects millions of couples worldwide. Oxidative stress
(OS) causes peroxidation of lipids and damage to spermatozoa, thus, reducing the quality of …
