Mitochondria, originally of bacterial origin, are highly dynamic organelles that have evolved
a symbiotic relationship within eukaryotic cells. Mitochondria undergo dynamic, stage …

Mammalian oocytes are long-lived cells in the human body. They initiate meiosis already in
the embryonic ovary, arrest meiotically for long periods in dictyate stage, and resume …

The decline of oocyte quality has profound impacts on fertilization, implantation, embryonic
development, and the genetic quality of future generations. One factor that is often ignored …

Melatonin (MT) is a potent antioxidant with useful applications in several fields. Due to the
capacity to scavenge free radicals and enhance cellular endogenous antioxidant defenses …

Protocols for the successful manipulation and preservation of semen in a given species
depend upon a fundamental knowledge of how spermatozoa respond to the …

The positive impact of melatonin on in vitro embryo production (IVEP) has been reported in
many domestic species; however, no studies have been carried out in camelids. We aimed …

In this review we compare situations under which the major cellular role of mitochondria,
oxidative phosphorylation (OXPHOS), is transiently suppressed. Two types of cellular …

OBJECTIVE: To clarify the relationship between oocyte maturation and mitochondria
distribution and assess the effects of in vitro maturation (IVM) on the distribution of …

The extensive replication of mitochondria during oogenesis and the wide variability in
mitochondrial DNA (mtDNA) copy numbers present in fully grown oocytes indicate that …

Embryologists working with livestock species were the pioneers in the field of
reprogramming by somatic cell nuclear transfer (SCNT). Without the “Dolly experiment,” the …
