Mammalian fertilization is a fascinating process that leads to the formation of a new
individual. Eggs and sperm are complex cells that must meet at the appropriate time and …

In vitro ovarian follicle culture is a reproduction technique used to obtain fertilizable oocytes,
for overcoming fertility issues due to premature ovarian failure. This requires the …

After mammalian ovulation, oocytes enter the oviduct, causing oocyte and oviduct changes.
Some studies have shown that follicular fluid exosomes (FEVs) play an important role in this …

In vitro embryo production (IVEP) is an extremely important tool for genetic improvement in
livestock and it is the biotechnology that has grown the most recently. However, multiple …

Domestic cat blastocysts cultured without the zona pellucida exhibit reduced implantation
capacity. However, the protein expression profile has not been evaluated in these embryos …

The oviduct consists of three parts: infundibulum (In), ampulla (Am) and isthmus (Is). They
have the same histological structure, but different physiological functions. In this study …

Assisted reproductive technologies are key to maintain genetic stocks of endangered wild
species, such as the Iberian ibex (Capra pyrenaica). Due to the low availability of ibex …

Oviductal (OF) and uterine (UF) fluids are a complex mixture of ions and macromolecules
dissolved in water, derived from the secretions of secretory cells and transudates of the …

The polyspermy occurrence is considerably lower under in vivo compared to in vitro embryo
culture conditions, suggesting that the presence of some factors in the maternal environment …
