Oxidative stress is a significant factor in male infertility, compromising sperm function and
overall reproductive health. As male infertility garners increasing attention, effective …

Background: Infertility, defined as the failure to conceive after one year of regular,
unprotected intercourse, affects 50–80 million people worldwide. A male factor is involved in …

Sperm quality assessment is the first step for evaluating male fertility and includes the
estimation of sperm concentration, motility, and morphology. Nevertheless, other parameters …

Oviductal extracellular vesicles (oEVs) have been proposed as key modulators of
gamete/embryo maternal interactions. The aim of this study was to examine the metabolite …

During cryopreservation, sperm undergoes structural and molecular changes such as ice
crystal formation, DNA fragmentation, and reactive oxygen species (ROS) production …

The endogenous amino acids serine and aspartate occur at high concentrations in free D-
form in mammalian organs, including the central nervous system and endocrine glands. D …

Overproduction of reactive oxygen species (ROS) during sperm cryopreservation has a
detrimental effect on sperm parameters. Therefore, the use of antioxidants in the sperm …

In the present study we tested whether regulation of the metabolome in bovine oviductal
fluid depended on the stage of the oestrous cycle, the side relative to ovulation and local …

This article reviews the animal models and experimental designs that have been used
during the past twenty years to demonstrate the prominent role played by D-aspartate (D …

Simple Summary A deeper knowledge of reproductive biology may be helpful in the donkey
to avoid the risk of extinction that some breeds are facing. The evaluation of metabolites in …
