Acrylamide (ACR) is a chemical compound with severe neurotoxicity, genotoxicity, carcinogenicity and reproductive toxicity. Recent studies showed that ACR impairs the function of reproductive organs, e.g., epididymis and testes. In vitro maturation of mouse oocyte is a sensitive assay to identify potential chemical hazard to female fertility. The aim of this study was to evaluate the adverse ef...

The goals and rhetoric of The Oncofertility Consortium [1] are aimed toward preserving cancer patients’ reproductive choices and facilitating their reproductive autonomy after cancer. While the end goals of oncofertility research are oriented toward safeguarding the possibility of biological reproduction for women and girls facing cancer treatments that may affect their reproductive capacity, c...

to investigate the effects of different hormonal treatments on the oocyte maturation in wild- caught grey mullet ( mugil cephalus ), fish were subjected to 4 different hormonal treatments as follows: (a) a control group received 0.5 ml/kg b.w. physiological saline, (b) fish injected with 20 mg/kg carp pituitary extract (cpe) as a priming dose followed by 200 µg/kg sgnrha as resolving dose, (c) ...

The objective of the development of assisted reproduction techniques in dogs and cats is their application to non-domestic canine and feline species, most of which are considered threatened or endangered. Among these techniques, an entirely in vitro system for embryo production is effectively an important tool for conservation of wildlife. In the last decade, progress has been made in embryo pr...

In recent years, the uptake of assisted reproductive techniques such as in vitro fertilisation has risen exponentially. However, there is much that is still not fully understood about the biochemical modifications that take place during the development and maturation of the oocyte. As such, it is essential to further the understanding of how oocyte manipulation during these procedures ultimatel...

Quantum dots (QDs) are useful novel luminescent markers, but their embryonic toxicity is yet to be fully established, particularly in oocyte maturation and sperm fertilization. Earlier experiments by our group show that CdSe-core QDs have cytotoxic effects on mouse blastocysts and are associated with defects in subsequent development. Here, we further investigate the influence of CdSe-core QDs ...

Assisted reproductive technologies (ART) for equine, such as in vitro oocyte maturation (IVM) and fertilization (IVF), has been slow with low success rates compared to other domestic species [1]. This is partly because mares are long-lived animals that gelded at an early age management [2].

the development of culture media able to mimic the preovulatory stage of follicular environment and support nuclear and cytoplasmic maturation of oocyte is important for in-vitro fertilization (ivf) programs. it seems that the best culture media for embryonic development and cell cleavage is the natural composition which surrounds the oocyte which has been used occasionally in human ivf program...
