The cellular mechanisms induced by elevated temperature on oocytes are not fully
understood. However, there is evidence that some of the deleterious effects of heat shock …

Astaxanthin, one of the most common carotenoids, elicits antioxidant effects on cellular
viability and embryonic development. This study was conducted to investigate the effects of …

Contents Early bovine embryos are vulnerable to heat stress during the first few days after
fertilization. The inhibitory effect of heat stress on embryonic development is known to be …

We investigated the effect of the antioxidant lycopene supplemented into the in vitro
maturation medium (TCM-199 with 20 ng/mL epidermal growth factor and 50 mg/mL …

As one of the most powerful natural antioxidants, astaxanthin (Ax) has begun to be applied
to the field of reproductive biology. Here we used porcine oocyte as a model to explore how …

Heat shock may disrupt oocyte function by increasing the generation of reactive oxygen
species (ROS). We evaluated the capacity of the antioxidant melatonin to protect oocytes …

Oxidative stress is partly responsible for the poor quality of IVM oocytes. The present study
investigated the effects of the antioxidant β-cryptoxanthin on the IVM of porcine oocytes and …

Heat stress is associated with increased production of reactive oxygen species (ROS) and
disruption of bovine oocyte function. Here, we examined whether the antioxidant melatonin …

Heat stress (HS) is especially harmful for bovine ovarian follicle development and oocyte
competence. Furthermore, HS causes premature aging in oocytes due to high levels of …

Purpose The effects of astaxanthin (Ax) on the in vitro development of bovine embryos
cultured under heat stress were investigated in combination with the assessment of its …
