This study was investigated to test in vitro-maturation rate of bovine follicular oocytes freezability of in vitro-matured bovine follicular oocytes with different stock solution in Glycerol and Propanediol, freezability of in vitro-rnatured bovine follicular oocytes on cryoprotectants, the viability of in vitro-rnatured bovine follicular oocytes by morphologically normal and FDA staining method. 1. The maturation rates of bovine follicular oocytes classified as grade A, B and C was 88, 63 and 21%, respectively. 2. Freezability of in vitro-matured bovine follicular oocytes on stock solution, TCM-199+5% FCS and m-PBS + 5% FCS was 61%(n=105), 48%(n=62) in $_1$M Glycerol and freeability of in vitro-matured bovine follicular oocytes on stock solution, TCM-199 +5% FCS and m-PBS + 5% FCS was 68%(n=112), 42%(n=57) in 1~2 Propanediol. The results indicate that freezability of in vitro-matured bovine follicular oocytes with different stock solution is important. 3. Freezability of in vitro-matured bovine follicular oocytes on cryoprotectants was Glycerol and PROH was 56%(n=167), 57%(n=169). The results indicate that PROH was superior to Glycerol. 4. The rates of morphologically normal IVM oocytes after thawing of cryopreserved oocytes with Glycerol and PROH were 39%(n=$_1$8), 65%(n=39), respectively. The results indicate that PROH was superior to Glycerol. 5. The fluorescent light intensity after thawing of cryopreserved oocytes classified with Positive, Partial-I, Partial-II, Negative with Glycerol and PROH. The results of FDA-positive 24%, 42%, Partial-I 17%, 10%, Partial- H 20%, 12%, FDA-negative 39%, 37%, and Partial-I, II, respectively.
