Contents Bull fertility is influenced by numerous factors. Although 20–40% of bulls in an
unselected population may have reduced fertility, few are completely sterile. Breeding …

Developmental arrest is one of the mechanisms responsible for the elevated levels of
embryo demise during the first week of in vitro development. Approximately 10–15% of IVF …

The postimplantation developmental potential of embryos can be affected by various forms
of cell death, such as apoptosis, at preimplantation stages. However, correct assessment of …

Several recent studies have indicated that radiofrequency electromagnetic fields (RF‐EMF)
have an adverse effect on human sperm quality, which could translate into an effect on …

The sperm plasma membrane is known to be critical to fertilization and to be highly
regionalized into domains of head, mid-and principal pieces. However, the molecular …

The use of somatic cells for coculture with embryos has been amply investigated to study
embryo maternal interactions. The use of bovine oviduct epithelial cells (BOEC) has been …

Cryopreservation causes a significant proportion of bovine oocytes to undergo degeneration
during subsequent culture. We investigated the degeneration mechanism of cryopreserved …

Surface membrane proteins have a key role in the sequential interactions between
spermatozoa and oocytes. The aim of this study was to characterize protein changes …

Boar-sperm cryopreservation is not usually performed immediately after semen collection,
but rather a holding time (HT) of 4 h–30 h at 17° C is spent before starting this procedure …

Highly evolutionary conserved heat shock proteins (HSPs) act as molecular chaperones in
regulation of cellular homeostasis and promoting survival. Generally they are induced by a …
