Table 1. Oocyte maturation rates of the control group and experimental groups (G1, G2, and G3) after hyperosmotic shock, induced by exposure to vitrification solutions. MII: number (n) of oocytes reaching the MII stages after 24h IVM. MI: number of oocytes (n) that reached the MI stage at some time point during IVM, this value includes both those, which remained at the MI stage after 24h, and those, which reached the MII stage. N: total number of cultivated oocytes in each group.
