Freezing technologies are very important to preserve gametes and embryos of animals with a good pedigree or those having high genetic value. The aim of this work was to compare immature andin vitromatured porcine oocytes regarding their morphology an

The present study examined the effect of nerve growth factor (NGF) on in vitro maturation (IVM), in vitro fertilisation (IVF) and subsequent embryonic development of porcine oocytes. Cumulus-oocyte complexes were cultured with or without 1.0 ng/ml NG

Several studies in cows have shown that plasma levels of chloride are positively correlated with the diameter of the preovulatory follicle (FD), establishing at the same time a significant positive association between plasma levels and intraoviducal

High levels of reactive oxygen species (ROS: superoxide, hydroxyl, hydrogen peroxide, nitric oxide, peroxynitrile) endanger sperm motility, viability, and function by interaction with membrane lipids, proteins, and nuclear and mitochondrial DNA (Sikk

The motion ability of mammalian spermatozoa is acquired during their epididymal transit but observed only upon dilution with seminal plasma (SP) at the time of ejaculation (Yanahimachi 1994 in The Physiology of Reproduction, New York: Raven Press). T

The process of cooling to 5°C prior to freezing produces physical and chemical stress on the sperm membrane associated with oxidative stress and reactive oxygen species (ROS) generation that reduces sperm viability and fertilizing ability. The addit
