Bovine in vitro embryo production is an inefficient process; while maturation and fertilization
proceed apparently normally, the proportion of embryos reaching the transferable …

The aim of this study was to evaluate the distribution of inhibin/activin alpha, beta (A) and
beta (B) subunits and follistatin in immature oocytes and in matured oocytes before and after …

OBJECTIVE: To quantify the effect on reproductive outcome of culturing and selecting
embryos using a novel time-lapse monitoring system (TMS). DESIGN: Retrospective …

Elevated concentrations of serum non-esterified fatty acids (NEFA), associated with maternal
disorders such as obesity and type II diabetes, alter the ovarian follicular micro-environment …

BACKGROUND Assisted reproduction technology offers the opportunity to observe the very
early stages of human development. However, due to practical constraints, for decades …

Increased oxidative activity and REDOX changes at the time of fertilization have been …

Embryo viability assessment is one of the most important and challenging tasks in IVF.
Evaluation of embryo quality is critical when selecting the best embryo (s) to transfer or …

The long-term effects of in vitro embryo culture on animal health are presently unknown,
however, current knowledge directs investigations toward understanding the mechanisms …

Mitochondria provide the major source of ATP for mammalian oocyte maturation and early
embryo development. Oxygen Consumption Rate (OCR) is an established measure of …

Life is a nonequilibrium phenomenon: Metabolism provides a continuous supply of energy
