 In this study, researchers examined the effectiveness of different fertilization conditions on reducing polyspermy rates in pig embryos. They found that modifying the co-incubation time between sperm and eggs, separating sperm using a pectoral treatment, and increasing the volume of culture medium, all improved fertilization success and blastocyst formation. These findings suggest that optimizing fertilization conditions can help reduce polyspermy rates and improve embryo development in pigs. This article was authored by Song He-li and Xiang Shun-chui.
