Producing high-competent oocytes during the in vitro maturation (IVM) is considered a key
step for the success of the in vitro production (IVP) of embryos. One of the known disruptors …

Seasonal breeding in buffalo is influenced by exogenous (photoperiod, climate, nutrition,
management) and endogenous (hormones, genotype) factors. Buffalo are negatively …

The present study assessed the effects of supplementation of different antioxidants on
oocyte maturation, embryo production, reactive oxygen species (ROS) production and …

Contents Melatonin enhances in vitro embryo development in several species by improving
the oocyte developmental competence during in vitro maturation (IVM). Melatonin has a …

Melatonin may have beneficial effects when used in oocyte maturation and embryo
development culture. The effect of melatonin during IVM on meiosis resumption 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 …

Gamete co‐incubation generates high free radical levels surrounding growing zygotes
which may impair subsequent embryo viability. Melatonin eliminates a wide variety of free …

Objective: Nutrients and antioxidants in the medium of immature oocyte have a profound
effect on maturation, fertilization and development of resulting embryos. In this study the …

Melatonin is a hormone mainly secreted by the pineal gland during the circadian cycle, with
low levels during the daytime and prominent levels during the night. It is involved in …

Background Vitrification as the most efficient method of cryopreservation, enables successful
storage of oocytes for couples who undergo specific procedures including surgery and …
