Abstract :
The incidence of cancer in whole world is increase and shifted to younger age (productive), no exception incidence of ovarian cancer. Women who are diagnosed with cancer at the productive age do not only need to get attention on survival but also on the possibility of the loss of fertility.Vitrification method has become a growing and promising technology in assisted reproductive technology. Freezing embryos are more common, freezing oocytes are longer growing because the physical characteristics of oocyte. Vitrified oocytes can be performed on mature and imature oocytes to get for more back up, therefore it is necessary to develop systems for freezing and oocyte maturation This study aims to compare the number of matur oocyte between bovine oocyte vitrification pre and post in vitro maturation. Maturation is operated in medium TC 100 μl covered with mineral oil in a petri dish with diameters 36 mm. Vitrification begins with washing oocyte in PBS of 20% serum for 1-2 minutes, followed by PBS + 20% serum + 10% ethylene glycol for 10-14 minutes, then transferred in 20% serum + PBS + 0.5 M sucrose + 15% ethylene glycol + PROH 15% for 25-30 seconds. Thawing is processed by submerging the oocytes in the media: 1). PBS + 20% serum + 0.5 M sucrose, 2). PBS + 20% serum + 0.25 M sucrose, and 3). PBS + 20% serum + 0.1 M sucrose. This study conclude that no difference on matur oocyte number between bovine oocyte vitrification pre and post in vitro maturation.
