In vitro maturation and fertilization (IVM, IVF) programs in pigs have some problems, these are low rates of cytoplasmic maturation and high percentages of polyspermy. To the present time, it is not clear if these difficulties are related to culture conditions during maturation. It has been shown that porcine follicular...
La exposición a xenobióticos, como los plaguicidas, puede ser una causa importante de disfunción reproductiva en humanos y animales. La atrazina y el fenoxaprop-etil, dos herbicidas de amplio uso, y el malatión y el diazinón, dos insecticidas organofosforados, se consideran sólo como ligeramente tóxicos par los animales, pero existen evidencias...
Background: Parabens (PBs) are compounds widely used in food and personal care products industry as antimicrobials and preservatives. Their indiscriminate use has allowed them to be detected in different ecosystems so that humans and other organisms are highly exposed. Methylparaben (MePB), compared with other PBs, is mostly detected in food,...
Perfluorooctane sulfonate (PFOS) is a persistent and bio-accumulative pollutant ubiquitous in wildlife and humans, which receives many concerns on its fate, transport, distribution, and toxicity. There is a concern about its presence in human blood and internal organs which points toward associations with multiple human health endpoints including fertility. Researches...
Malathion is one of the most commonly used insecticides, recent findings have demonstrated that it induces oxidative stress in somatic cells, but there are not enough studies demonstrating this effect in germ cells. Malathion impairs porcine oocyte viability and maturation, but studies have not shown how oxidative stress affects maturation...
