Exogenous ascorbic acid enhances vitrification survival of porcine in  vitro-developed blastocysts but fails to improve the in vitro embryo production outcomes

In this study, the effects of addition of the antioxidant ascorbic acid (AsA) were evaluated during porcine in  vitro embryo production (IVP) and vitrification. In experiment 1, the effects of AsA supplementation during IVM, IVF and IVC were evaluated, using a total of 2744 oocytes in six replicates. The IVM, IVF and embryo IVC media were supplemented or not (control) with 50 μg/mL AsA in all possible com binations. No significant effects of AsA were detected in any of the maturation, fertilization or embryo development parameters assessed.
