This study aimed to evaluate oocyte vitrification efficiency using in-vivo matured (IVO) versus rescued in-vitro matured (IVM) oocytes. The results show that oocyte survival (85% versus 81%), fertilization (86% versus 76%) and cleavage rate (98% versus 89%) was not significantly different in IVO oocytes compared with rescued IVM sibling oocytes. The fertilized oocytes from IVO and IVM groups were cultured to blastocyst stage; however, embryo development was significantly reduced in the rescued IVM group (72% versus 15%). Embryo transfer was only performed with the embryos derived from IVO oocytes on day 5; 42 blastocysts were transferred to 18 recipients; 16 of 18 recipients had positive beta-human chorionic gonadotrophin and a total of 26 fetal cardiac activities were detected in 15 recipients (implantation: 26/42, 61.9%). Ten of the 15 recipients have delivered 19 healthy babies, and the other five pregnancies are still ongoing. These data indicate that the combination of oocyte vitrification and rescued IVM not only yield a new strategy to extend the pool of total fertilizable oocytes, but also demonstrate that the efficiency of vitrified/warmed oocytes can be comparable to fresh oocytes with regard to clinical outcomes.
